Nature of Business and Liquidity [Abstract]
Nature of Business and Liquidity1.
Nature of Business and Liquidity PolyMet Mining Corp. was incorporated in British Columbia, Canada on March 4, 1981 under the name Fleck Resources Ltd. and changed its
name to PolyMet Mining Corp. on June 10, 1998. Through its 100%-owned subsidiary, Poly Met Mining, Inc. (“PolyMet US” and, together with PolyMet Mining Corp., “PolyMet” or the “Company”), the Company is engaged in the exploration and development of
natural resource properties. The Company’s primary mineral property is the NorthMet Project (“NorthMet” or “Project”), a polymetallic project in northeastern Minnesota, United States of America, which comprises the NorthMet copper-nickel-precious
metals ore body and the Erie Plant, a processing facility located approximately six miles from the ore body. The realization of the Company’s investment in NorthMet and other assets is dependent upon various factors, including the existence of
economically recoverable mineral reserves, the ability to obtain and maintain permits necessary to construct and operate NorthMet, the ability to obtain financing necessary to complete the development of NorthMet, and generate future profitable
operations or alternatively, disposal of the investment on an advantageous basis. The corporate address and records office of the Company are located at 100 King Street West, Suite 5700, Toronto,
Ontario, Canada M5X 1C7, and 700 West Georgia, 25 th 444
Cedar Street, Suite 2060, St. Paul, Minnesota, United States of America, 55101 On December 7, 2017, the Board of Directors approved a resolution to change the year-end from January 31 to December 31. Accordingly, the
comparative period in these consolidated financial statements is at and for the eleven months ended December 31, 2017. The consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of
assets and the settlement of liabilities in the normal course of operations.
Liquidity risk is the risk the Company will not be able to meet its financial obligations as they become due and arises through the excess of financial obligations over financial assets due at any
point in time. As at December 31, 2018, the Company had cash of $13.857 million and a working capital deficiency of $225.359 million primarily due to $56.984 million secured convertible debt and $178.483 million
secured non-convertible debt owed to Glencore AG, a wholly owned subsidiary of Glencore plc (together “Glencore”) being classified as a current liability. Subsequent to year end, the Company entered into an agreement with Glencore to extend the
maturity date of the secured convertible and non-convertible debt to provide the Company time to prepare for and complete a rights offering by June 30, 2019, fully backstopped by Glencore, to raise sufficient funds to repay all outstanding debt
(see Note 16). Management believes, based upon the underlying value of the NorthMet Project, the receipt of all permits necessary to construct and
operate potential financiers to allow

Basis of Presentation [Abstract]
Basis of Presentation2.
Basis of Presentation a) Statement of Compliance The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued
by the International Accounting Standards Board (“IASB”). The financial statements were approved by the Board of Directors on March 28, 2019. b) Basis of Consolidation and Presentation The consolidated financial statements include the accounts of the Company and its wholly‑owned subsidiary. Intercompany balances and
transactions have been eliminated on consolidation. The consolidated financial statements have been prepared under the historical cost convention. All dollar amounts presented are in United
States (“U.S.”) dollars unless otherwise specified. c) Change in Accounting Policies On January 1, 2018, the Company adopted the following new accounting standards that were previously issued by the IASB. Certain other new
standards and interpretations have been issued and were effective as of January 1, 2018 but did not have a material impact on the Company’s financial statements and are therefore not discussed below. The accounting policies discussed below reflect the Company’s adoption of IFRS 9 - Financial Instruments, effective January 1, 2018, and
IFRS 16 - Leases, which had an effective date of January 1, 2019 but for which the company early adopted as of January 1, 2018. For the eleven months ended December 31, 2017, the Company applied policies based on IAS 39 and IAS 17 and the effects of
the transition from IAS 39 to IFRS 9 and from IAS 17 to IFRS 16 are described below. IFRS 9 – Financial Instruments IFRS 9 addresses the classification, measurement and recognition of financial assets and financial liabilities. This standard replaces
parts of IAS 39 - Financial Instruments: Recognition and Measurement. The Company adopted IFRS 9 effective January 1, 2018 on a retrospective basis without restating prior period comparatives. IFRS 9 requires financial assets to be classified into the following measurement categories: fair value through profit and loss, fair
value through other comprehensive income, and those measured at amortized cost. The determination is made at initial recognition. On transition, the EIP receivable (see Note 5) previously classified as available-for-sale and measured at fair value
through other comprehensive income was re-classified as fair value through profit or loss with changes in fair value recognized in the statement of loss instead of through other comprehensive loss. Adoption resulted in re-classification of $0.210
million to the opening deficit from accumulated other comprehensive loss for cumulative gains on the EIP receivable. The following table shows the original measurement categories under IAS 39 and the new measurement categories under IFRS 9 for the
Company’s financial assets as at January 1, 2018:

Fair value through profit or loss IFRS 16 – Leases IFRS 16 replaces IAS 17 – Leases. The new standard requires capitalization of certain leases by the leasee and results in accounting
treatment similar to finance leases under IAS 17 - Leases. Exemptions for leases of very low value or short duration leases are applicable. The new standard results in an increase in lease assets and liabilities for the lessee. Under the new standard
the treatment of all lease expenses is aligned in the statement of earnings with depreciation, and an interest expense component recognized for each lease, in line with finance lease accounting under IAS 17 - Leases. The Company early adopted IFRS 16 effective January 1, 2018 on a modified retrospective basis without restating prior period
comparatives. As a result, the Company recorded a $0.211 million lease asset and corresponding lease liability for the one qualifying office lease that has been recognized over the remaining term. The Company’s other leases (see Note 3) are leases
to explore mining rights, which are excluded from IFRS 16’s scope. The following table summarizes the impact of adopting IFRS 9 - Financial Instruments and IFRS 16 - Leases:

) d) Critical Accounting Estimates The preparation of consolidated financial statements in conformity with IFRS requires the use of certain critical accounting estimates.
These critical accounting estimates require management to make estimates that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as at the date of the financial statements. Critical accounting estimates used in the preparation of the consolidated financial statements are as follows: Determination of mineral reserves Reserves are estimates of the amount of product that can be economically and legally extracted from the Company’s property. In order to
estimate reserves, estimates are required about a range of geological, technical and economic factors, including quantities, production techniques, production costs, capital costs, transport costs, demand, prices and exchange rates. Estimating the
quantity of reserves requires the size, shape and depth of deposits to be determined by analyzing geological data. This process may require complex and difficult geological judgments to interpret the data. In addition, management will form a view of
forecast sales prices, based on current and long-term historical average price trends. Changes in the proven and probable reserves estimates may impact the carrying value of property, plant and equipment, rehabilitation provisions, recognition of
deferred tax amounts and depreciation, depletion and amortization. Provision for Environmental Rehabilitation Costs Provisions for environmental rehabilitation costs associated with mineral property, plant and equipment, are recognized when the Company
has a present legal or constructive obligation that can be estimated reliably, and it is probable an outflow of economic benefits will be required to settle the obligation. Provisions are determined by discounting the expected future cash flows at a
pre-tax risk-free rate that reflects current market assessments of the time value of money. The Company’s estimates of its ultimate environmental rehabilitation liabilities could be affected by changes in regulations, changes in
the extent of environmental rehabilitation required, changes in the means of rehabilitation, changes in the extent of responsibility for the financial liability, changes in operating plans, or changes in cost estimates. The operations of the Company
may in the future be affected from time to time in varying degrees by changes in environmental regulations, including those for future removal and site restoration costs. Both the likelihood of new regulations and their overall effect upon the
Company may vary greatly and are not predictable. The Company’s provision for environmental rehabilitation cost obligations represents management’s best estimate of the present value of
the future cash outflows required to settle the liability. See additional discussion in Note 6. e) Critical Accounting Judgments The preparation of consolidated financial statements in conformity with IFRS requires the use of certain critical accounting judgments.
These critical accounting judgments require management to make judgments that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as at the date of the financial statements. Critical accounting judgments used in the preparation of the consolidated financial statements are as follows: Impairment of non-financial assets The
carrying amounts of the Company’s non-financial assets, including mineral property, plant and equipment, and intangible
are reviewed at each reporting date or when events or changes in circumstances occur that indicate the asset may not be
recoverable to determine whether there is any indication of impairment. If any such indication exists, the
asset’s recoverable amount is estimated at the greater of its value in use and its fair value less costs of
disposal. In assessing value in use, the estimated future cash flows are discounted to their present value using a
pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the
asset. An impairment loss is recognized if the carrying amount of an asset exceeds its estimated recoverable
amount. An impairment loss previously recorded is reversed if there has been a change in the estimates used to
determine the recoverable amount resulting in an increase in the estimated service potential of an asset. The Company considers both external and internal sources of information in assessing whether there are any indications of impairment.
External sources of information the Company considers include changes in the market, economic, and legal environment in which the Company operates that are not within its control and affect the recoverable amount. Internal sources of information the
Company considers include indications of economic performance of the asset. The carrying value of mineral property, plant, and equipment, and intangible at the balance sheet date are described in Notes 4 and 5,
respectively. No impairment indicators were identified on the mineral property, plant and equipment or intangible for the twelve months ended December 31, 2018 or eleven months ended December 31, 2017. Going concern assumptions The Company must assess its ability to continue as a going concern and prepare financial statements on a going concern basis unless it
either intends to liquidate or cease trading or has no realistic alternative but to do so. In assessing whether the going concern assumption is appropriate, the Company takes into account all available information about the future, which is at
least, but is not limited to, twelve months from the end of the reporting period.
f)
Summary of Significant Accounting Policies Cash and Cash Equivalents and Restricted Cash Deposits The Company considers cash and cash equivalents to include amounts held in banks and highly liquid investments with original maturities of
three months or less. Restricted Cash Deposits are held in a trust account and invested in highly liquid investments with a major financial institution as security and collateral for reclamation activities. Financial Assets All financial assets are initially recorded at fair value and designated upon inception as one of the following categories: amortized cost
or fair value through profit or loss (“FVTPL”). Financial assets classified as FVTPL are measured at fair value with gains and losses recognized through profit and loss. Financial assets classified as amortized cost are measured at amortized cost
using the effective interest method less any allowance for impairment. The effective interest method is a method of calculating the amortized cost of a financial asset and of allocating interest income over the relevant period. The effective
interest rate is the rate that discounts estimated future cash receipts through the expected life of the financial asset, or, where appropriate, a shorter period. The Company recognizes loss allowances for Expected Credit Losses (“ECL”) for amounts
receivable not measured at FVTPL. Loss allowances for amounts receivable are measured at an amount equal to lifetime ECL. ECL is a probability-weighted estimate and measured as at the present value of all cash shortfalls including the impact of
forward looking information. The loss allowance is presented as a deduction to amounts receivable. Transaction costs associated with FVTPL financial assets are expensed as incurred, while transaction costs associated with amortized cost financial
assets are included in the initial carrying amount of the asset. See additional discussion in Note 15. Mineral Property Exploration and evaluation costs incurred prior to a Definitive Feasibility Study (“DFS”) are expensed as incurred. Development costs
incurred subsequent to a DFS and mineral property acquisition costs are capitalized until the property is placed into production, sold, allowed to lapse or abandoned. As a result of the DFS, NorthMet entered the development stage effective October 1,
2006. The Company has capitalized development expenditures related to NorthMet from that date. Upon commencement of production, related property acquisition and development costs are amortized on a unit of production basis over the
estimated proven and probable mineral reserves not to exceed the assets’ useful lives. Plant and Equipment Plant and equipment are recorded at historical cost less accumulated depreciation and if applicable, accumulated impairment losses.
Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, if it is probable that the future economic benefits of the expenditure will flow to the Company and its cost can be measured reliably.
The carrying amount of a replaced part is derecognized. All other repairs and maintenance are charged to the statement of loss and comprehensive loss during the period in which they are incurred. Depreciation of plant and equipment is calculated using the cost of the asset, less its residual value, over the estimated useful life of
the asset on a unit of production or straight-line basis, as appropriate. Leases The Company recognizes a right-of-use asset and a lease liability at the lease commencement date. The right-of-use asset is initially
measured at cost, which comprises the initial amount of the lease liability, plus any initial direct costs incurred and an estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset or the site on which it is
located, less any lease incentives received. The right-of-use asset is subsequently depreciated using the straight-line method from the commencement date to the earlier of the end of the useful life of the right-of-use asset or the end of the lease
term. The lease liability is initially measured at the present value of the lease payments, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Company’s incremental borrowing rate. Generally,
the Company uses its incremental borrowing rate as the discount rate. Intangible Intangible costs and related acquisition costs are capitalized until the wetland credits are used, sold, or abandoned. Wetland credits
are used to offset and mitigate wetlands disturbed during construction and operation of NorthMet. As such, costs will be transferred to Mineral Property, Plant and Equipment once placed into service and
amortized on a unit of production basis over the estimated proven and probable mineral reserves not to exceed the assets’ useful lives. See additional discussion in Note 5. Financial Liabilities All financial
liabilities are initially recorded at fair value and designated upon inception as FVTPL or other financial liabilities.
Financial liabilities classified as FVTPL are initially recognized at fair value with directly attributable transaction costs
expensed as incurred. At the end of each reporting period, financial liabilities at FVTPL are measured at fair value, with
changes in fair value recognized directly in profit or loss in the period in which they arise. Financial liabilities classified
as other financial liabilities are initially recognized at fair value less directly attributable transaction costs and subsequently
measured at amortized cost using the effective interest method which calculates the amortized cost of a financial liability and
allocates interest expense over the expected life of the financial liability. Exchanges of instruments and modifications to debt are assessed using quantitative and qualitative factors to consider whether the
exchange or modification constitutes an extinguishment of the original financial liability and establishment of a new financial liability. In the case of extinguishment, any fees or costs incurred are recognized in profit or loss in the period in
which they arise. Where the terms in an exchange or modification are not assessed to be substantially different, a modification gain or loss is recognized at an amount equal to the difference between the modified cash flows discounted at the
original effective interest rate and the carrying value of the debt. The carrying value of the debt is adjusted for this modification gain or loss, directly attributable transaction costs, and any cash paid to or received from the debt holder. See
additional discussion in Note 15. Borrowing costs Borrowing costs directly attributable to the acquisition, construction or production of a qualifying asset are capitalized as part of the
cost of that asset until such time as the asset is substantially complete and ready for its intended use or sale. Where funds have been borrowed specifically to finance an asset, the amount capitalized is the actual borrowing costs incurred. Where
the funds used to finance an asset form part of general borrowings, the amount capitalized is calculated using a weighted average of rates applicable to relevant borrowings of the Company during the period. Other borrowing costs not directly
attributable to a qualifying asset are expensed in the year incurred. Classification in the cash flow statement is in accordance with the classification of the underlying asset to which those payments were capitalized. Share‑Based Compensation All share-based compensation awards made to directors, employees and non-employees are measured and recognized using a fair value based
method. For directors and employees, or those providing services similar to employees, the fair value of options is determined using the Black-Scholes pricing model. The fair value of the bonus shares, restricted shares, and restricted share units
expected to be settled in shares are calculated using the intrinsic value of the shares at issuance and is amortised over the vesting period. For awards expected to be settled in cash, the change in market value and corresponding liability is
adjusted to fair value at each reporting period. The award is accrued and charged over the vesting period either to operations or mineral property plant and equipment, with the offsetting
credit to equity reserves for equity settled awards or liabilities for cash settled awards. If and when share options are ultimately exercised or bonus shares, restricted shares, and restricted share units vest, the applicable amounts are
transferred to share capital or removed from liabilities. Certain awards vest upon achievement of non-market performance conditions. On a quarterly basis, management assesses the probability of
achieving those performance conditions using the best available information and estimates the appropriate vesting period. When the Company amends the terms of share options, the incremental change in the fair value of the options due to the amendment, as
determined using the Black-Scholes pricing model, is recognized over the vesting period in the statement of loss or capitalized as appropriate. Share Purchase Warrants The Company issues share purchase warrants in connection with certain financing transactions. The fair value of the warrants, as
determined using the Black-Scholes pricing model or fair value of goods or services received, is credited to equity reserves. The recorded value of share purchase warrants is transferred to share capital upon exercise. Foreign Currency Translation The U.S. dollar is the functional currency of the Company and its wholly-owned subsidiary. Amounts in the consolidated financial
statements are expressed in U.S. dollars unless otherwise stated. Transactions in foreign currencies are translated into the functional currency at the exchange rates at the date of the transactions. Monetary assets and liabilities of the Company’s
operations denominated in a currency other than the U.S. dollar are translated using exchange rates prevailing at the balance sheet date. Revenue and expense items are translated at the exchange rates in effect at the date of the underlying
transaction. Exchange differences are recognized in net loss in the year in which they arise. Loss Per Share Loss per share is computed by dividing the loss for the year by the weighted average number of common shares outstanding during the year.
Basic and diluted loss per share for each year presented are the same due to the effect of potential issuances of shares under warrant or share option agreements being, in total, anti-dilutive. Income Taxes and Deferred Taxes The income tax expense or benefit for the year consists of two components: current and deferred. Current tax is the expected tax payable or receivable on the taxable profit or loss for the year. Current tax is calculated using tax
rates and laws that were enacted or substantively enacted at the balance sheet date in each of the jurisdictions and include any adjustments for taxes payable or recovery in respect of prior periods. Taxable profit or loss differs from profit or loss as reported in the Consolidated Statements of Loss and Comprehensive Loss because of
items of income or expense that are taxable or deductible in other years, and items that are never taxable or deductible. Deferred tax is recognized on temporary differences between the carrying amounts of assets and liabilities in the financial statements and
the corresponding tax basis used in the computation of taxable profit. Deferred tax liabilities are generally recognized for all taxable temporary differences not eligible for offset. Deferred tax assets are generally recognized for all deductible
temporary differences, loss carry forwards and tax credit carry forwards to the extent that it is probable that taxable profits will be available against which they can be utilized. To the extent that the Company does not consider it to be probable
that taxable profits will be available against which deductible temporary differences, loss carry forwards, and tax credit carry forwards can be utilized, a deferred tax asset is not recognized.

been paid to date with the next annual payment of $0.030 million due in November 2019. The lease payments are considered advance royalty payments and will be deducted from future production royalties payable to the lessor,
which range from 3% to 5% based on the net smelter return per ton received by the Company. The Company’s recovery of $3.000 million in advance royalty payments to RGGS Land & Minerals Ltd., L.P. is subject to the lessor receiving an amount not
less than the amount of the annual lease payment due for that year. The Company’s recovery of $0.219 million in advance royalty payments to LMC Minerals is subject to the lessor receiving an amount not less than the amount of the annual lease
payment due for that year.

395,115 Erie Plant, Minnesota, U.S.A. In November 2005, the Company acquired from Cliffs Erie LLC, a subsidiary of Cleveland Cliffs Inc. (together “Cliffs”) large parts of the
Erie Plant, a processing facility located approximately six miles from the ore body. In December 2006, the Company acquired from Cliffs additional property and associated rights sufficient to provide it with a railroad
connection linking the mine development site and the Erie Plant. The transaction also included a railcar fleet, locomotive fueling and maintenance facilities, water rights and pipelines, administrative offices on site and an additional 6,000 acres
of land to the east and west of the existing tailings storage facilities. The consideration paid for the Erie Plant and associated infrastructure was $18.9 million in cash and 9,200,547 shares at a fair market
value of $13.953 million. As part of the consideration, the Company indemnified Cliffs for reclamation and remediation obligations of the acquired property (see Note 6). During the twelve months ended December 31, 2018, the Company capitalized 100% of the borrowing costs on the convertible debt (see Note 8)
and non-convertible debt (see Note 9) in the amount of $20.560 million (eleven months ended December 31, 2017 - $18.512 million) as part of the cost of NorthMet assets. Costs to acquire the surface rights over the mineral rights were reclassed from
mine plan and development to mineral property acquisition following the land exchange closing in June 2018 which resulted in cash proceeds of $0.425 million and a non-cash loss of $0.553 million based on independent valuation appraisals of the lands
exchanged. As NorthMet assets are not in use or capable of operating in a manner intended by management, no depreciation or amortization of these assets has been recorded to December 31, 2018.

2,533 In April 2015, the Company entered into an agreement with EIP Minnesota, LLC (“EIP”) whereby EIP will seek to sell wetland credits the
Company is unable to use for the NorthMet Project to third parties and, over time, reimburse the Company for its costs. In February 2017, additional wetland credits the Company is unable to use were added to the receivable under the same terms as
the April 2015 agreement. The timing of EIP’s sale to third parties and reimbursement of the Company is uncertain and volatile. The Company initially recognized the February 2017 receivable at fair value calculated using a 9.75% discount rate and
15-year term resulting in a receivable of $0.564 million and a non-cash loss of $1.324 million. The EIP receivable is recorded at fair value at each reporting period, based on management’s best estimate of cash flows expected from future sales by
EIP. Fair value changes were accounted for through other comprehensive income or loss prior to adoption of IFRS 9 after which changes are accounted for through income or loss. In October 2017, the Company entered into an agreement with EIP Credit Co., LLC to reserve wetland bank credits the Company can use for
the NorthMet Project for a minimum of five years in exchange for an initial down payment applicable to the purchase price, contractual transfer of certain lands, and annual option payments not applicable to the purchase price. The initial
consideration paid was $0.810 million in cash and $2.320 million in lands valued using Level 3 measurements (see Note 15) and resulted in a non-cash charge of $0.469 million. Annual option payments of $0.250 million are expensed as incurred whereas
option exercise payments will be recorded to Intangible and transferred to Mineral Property, Plant and Equipment once placed into service. During the twelve months ended December 31, 2018, the Company exercised part of its rights and purchased
wetland bank credits, which resulted in a $21.055 million addition to Intangible.

64,136 Federal, state and local laws and regulations concerning environmental protection affect the Company’s assets. As part of the
consideration for the asset acquisitions from Cliffs (see Note 4), the Company indemnified Cliffs for reclamation and remediation obligations of the acquired property. The Company’s provisions are based upon existing laws and regulations. It is not
currently possible to estimate the impact on operating results, if any, of future legislative or regulatory developments. In April 2010, Cliffs entered into a consent decree with the Minnesota Pollution Control Agency (“MPCA”) relating to alleged violations on
the Cliffs Erie Property. This consent decree required both short-term and long-term mitigation. Field studies were completed in 2010 and 2011 and short-term mitigations approved by the MPCA were initiated in 2011. In April 2012, long-term
mitigation plans were submitted to the MPCA and, in October 2012, the MPCA approved plans for pilot tests of various treatment options to determine the best course of action. Although there is substantial uncertainty related to applicable water
quality standards and engineering scope, the October 2012 response from the MPCA, subsequent communications amongst the MPCA, Cliffs and the Company, and closure plans reflected in the Permit to Mine support the long-term mitigation plans included in
the Company’s environmental rehabilitation provision. The Company’s best estimate of the environmental rehabilitation provision as at December 31, 2018 was $61.107 million (December 31, 2017 -
$65.402 million) based on estimated cash flows required to settle this obligation in present day costs of $71.146 million (December 31, 2017 - $73.301 million), a projected inflation rate of 2.00% (December 31, 2017 – 2.00%), a market risk-free
interest rate of 3.13% (December 31, 2017 – 2.58%) and expenditures expected to occur over a period of approximately 30 years. The decrease during the twelve months ended December 31, 2018 was primarily due to revisions to estimated cash flows as a
result of changes in the market risk-free interest rate and liabilities discharged for rehabilitation work completed in the processing plant. The decrease during the eleven months ended December 31, 2017 was primarily due to revisions to estimated
cash flows as a result of closure plans reflected in the Permit to Mine application. On November 1, 2018, the Company received the Permit to Mine for NorthMet and certain other permits , including cash primarily Financial assurance obligations reviewed annually based on Company’s planned reclamation activities, with total assurance related financial instruments adjusted accordingly if the underlying estimated reclamation costs are revised. The Company terminate these financial instruments only upon meeting site reclamation requirements and securing approval from . cash the first year of mining operations until the eighth year after which annual contributions will be prorated based on the expected reclamation obligation at the end of mining

2010 in three tranches; a $20.0 million placement of PolyMet common shares in calendar 2011 in one tranche; a $20.960 million purchase of PolyMet common shares in the 2013 Rights Offering; and a $10.583 million purchase of PolyMet common
shares in the 2016 Private Placement;

Convertible debt (“Glencore Convertible Debt”) – agreement comprising $25.0 million initial principal secured convertible debentures drawn in
four tranches (see Notes 8 and 16); and

Non-convertible debt (“Glencore Non-Convertible Debt”) – five separate agreements
comprising $30.0 million initial principal secured debentures in calendar 2015 drawn in four tranches; an $11.0 million initial principal secured debenture in calendar 2016 drawn in one tranche; $14.0 million initial principal secured

with the fifth tranche in the amount of $15.0 million cancelled subsequent to year end (see Notes 9 and 16).
As a result of these financing transactions and the purchase by Glencore of PolyMet common shares previously owned by Cliffs, Glencore's
ownership and ownership rights of PolyMet as at December 31, 2018 comprises:

92,836,072 shares representing 28.9% of PolyMet's issued shares (December 31, 2017 - 92,836,072 shares);

Glencore Convertible Debt exchangeable through the exercise of an exchange warrant (“Exchange Warrant”) at $1.2696 per share into 44,303,743 common
shares of PolyMet (including capitalized and accrued interest as at December 31, 2018), and where the exercise price and the number of shares issuable are subject to conventional anti-dilution provisions (see Notes 8 and 16);

Warrants to purchase 6,458,001 common shares at $0.8231 per share at any time until March 31, 2019, subject to mandatory exercise if the 20-day
volume weighted average price (“VWAP”) of PolyMet common shares is equal to or greater than 150% of the exercise price and PolyMet has received permits and construction finance is available (“Exercise Triggering Event”), and where the
exercise price and the number of warrants are subject to conventional anti-dilution provisions. See 2018 Agreement below for additional details;

Warrants to purchase 7,055,626 common shares at $1.00 per share at any time

subject to conventional anti-dilution provisions; and

Warrants to purchase 625,000 common shares at $0.7797 per share at any time until October 28, 2021, and where the exercise price and the number of
warrants are subject to conventional anti-dilution provisions. If Glencore were to exercise all of its rights and obligations under these agreements, it would own 151,278,442 common
shares of PolyMet, representing 39.8% on a partially diluted basis, that is, if no other options or warrants were exercised or 36.1% on a fully diluted basis, if all other options and warrants were exercised as at December 31, 2018. 2017 Agreements In September 2017, the Company agreed to issue to Glencore secured debentures with a total principal amount of $20.0
million. The debentures bear interest at twelve month US dollar LIBOR plus 15.0% and are due on the earlier of (i) March 31, 2018 or (ii) the availability of at least $100 million of debt or equity financing or (iii) when it is prudent for PolyMet
to repay the debt, on which date all principal and interest accrued to such date will be due and payable. The Tranche N Debenture in the amount of $15.0 million was issued on September 18, 2017. The Tranche O Debenture in the amount of $5.0 million
was issued on January 18, 2018. Transaction costs for the financing were $0.083 million. The maturity date of these debentures was extended to March 31, 2019 as noted below. 2018 Agreement On March 23, 2018, the Company amended its financing arrangement with Glencore. The maturity date of the Convertible Debt and the
Non-Convertible Debt was extended to the earlier of (i) March 31, 2019 or (ii) the availability of at least $100 million of debt or equity financing or (iii) when the Company elects to repay the debt early and demonstrates that such repayment is
prudent. The interest rate was reduced from twelve month US dollar LIBOR plus 15.0% to twelve month US dollar LIBOR plus 10.0% effective April 1, 2018. The convertibility of the Convertible Debt was extended to March 31, 2019 and 6,458,001
purchase warrants were reissued with an expiration date of March 31, 2019 and an exercise price of $0.8231 per share, both of which were approved by the NYSE American and TSX. All other terms of both the debentures and the warrants described above
remain unchanged. In addition, the Company agreed to issue to Glencore secured debentures with a total principal amount of up to $80 million at the
Company’s option. The debentures bear interest at twelve month US dollar LIBOR plus 10.0% and if issued, are due on the earlier of (i) March 31, 2019 or (ii) the availability of at least $100 million of debt or equity financing or (iii) when the
Company elects to repay the debt early and demonstrates that such repayment is prudent, on which date all principal and interest accrued to such date will be due and payable. The Tranche P Debenture in the amount of $20.0 million was issued on May
7, 2018. The Tranche Q Debenture in the amount of $15.0 million and Tranche T Debenture in the amount of $10 million were issued on October 25, 2018. The Tranche S Debenture in the amount of $20.0 million was issued on December 18, 2018. Under the
extension agreement and repayment plan agreed to subsequent to December 31, 2018, the commitment to issue Tranche R in the amount of $15.0 million was cancelled. See
additional discussion in Note 16. The transaction has been accounted for as a modification of the existing debentures with a $4.109 million modification loss
recognized during the twelve month period ending December 31, 2018, consisting of the following:

$3.142 million to increase the convertible debt carrying value to the revised cash flows discounted using the original effective
interest rate of 6.7%;

$1.452 million to reduce the non-convertible debt carrying value to the revised cash flows discounted using the original effective
interest rate of 14.9%;

$2.331 million to recognize fair value of the purchase warrants issued; and

$0.088 million to recognize transaction costs which were allocated on a pro rata basis to the Glencore Non-Convertible Debt and
Glencore Convertible Debt.

Issuances for Cash and Land Acquisition During the twelve months ended December 31, 2018 the Company issued 815,500 shares (December 31, 2017 – nil) pursuant to
the exercise of share options and warrants for proceeds of $0.742 million (December 31, 2017 - $nil). During the twelve months ended December 31, 2018 the Company issued 128,750 shares (December 31, 2017 – 396,616 shares)
to maintain land purchase options with the shares valued at $0.123 million (December 31, 2017 - $0.256 million).
b)
Share-Based Compensation The Omnibus Share Compensation Plan (“Omnibus Plan”) was created to align the interests of the Company’s
employees, directors, officers and consultants with those of shareholders. Effective May 25, 2007, the Company adopted the Omnibus Plan, which was approved by the Company’s shareholders on June 27, 2007, modified and further ratified and reconfirmed
by the Company’s shareholders most recently on June 27, 2018. The Omnibus Plan restricts the award of share options, restricted shares, restricted share units, and other share-based awards to 10% of the common shares issued and outstanding on the
grant date, excluding 2,500,000 common shares underlying options pursuant to an exemption approved by the Toronto Stock Exchange. During the twelve months ended December 31, 2018, the Company recorded $2.202 million for
share-based compensation (December 31, 2017 - $1.550 million) with $1.742 million expensed to share-based compensation (December 31, 2017 - $1.318 million) and $0.460 million capitalized to mineral property, plant and equipment (December 31, 2017 -
$0.232 million). The offsetting entries were to equity reserves for $1.787 million (December 31, 2017 - $1.111 million), share capital for $0.105 million (December 31, 2017 - $nil) and payables for $0.310 million (December 31, 2017 - $0.439). Total
share-based compensation for the twelve months ended December 31, 2018 comprised $0.803 million for share options (December 31, 2017 - $0.368 million), $1.294 million for restricted shares and restricted share units (December 31, 2017 - $1.182
million), and $0.105 million for issuance of unrestricted shares (December 31, 2017 - $nil). Exercise of share options and warrants and vesting of restricted share units during the twelve months ended December 31, 2018 resulted in $0.783 million
being transferred from equity reserves to share capital (December 31, 2017 - $0.365 million).

million to be expensed and capitalized over the vesting periods. During the twelve months ended December 31, 2018, there were 316,714 restricted share units settled upon vesting with $0.377 million in
cash. As at December 31, 2018, outstanding restricted shares and restricted share units were scheduled to vest upon completion of specific
targets (Permits – 134,891; Construction Finance – 750,000; Production – 410,701) or dates (1,529,093 between January 2019 and June 2020). The remaining 523,222 outstanding restricted shares and restricted share units have vested but share delivery
is deferred until retirement, termination, or death. The Company expects 721,961 outstanding restricted share units will be settled in cash and the remainder will be settled in shares as allowed under the Omnibus Plan.
e)
Bonus Shares The bonus share incentive plan was established for the Company’s directors and key employees and was approved by the disinterested
shareholders at the Company’s shareholders’ meeting held in May 2004. The Company has authorized 3,640,000 bonus shares for the achievement of Milestone 4 representing commencement of commercial production at NorthMet at a time when the Company has
not less than 50% ownership interest in NorthMet. At the Company’s Annual General Meeting of shareholders held in June 2008, the disinterested shareholders approved issuance of these shares upon achievement of Milestone 4. Regulatory approval is
also required prior to issuance of these shares. Details of the bonus shares are as follows:

Share-based payment represents the amount capitalized or expensed during the period (see Note 10). There are agreements with key employees, including the President and Chief Executive Officer, containing severance provisions for
termination without cause or in the event of a change in control. No other PolyMet director has an agreement providing for benefits upon termination. As a result of Glencore’s ownership of 28.9% it is also a related party. In addition to the transactions described in Notes 7, 8, 9 and
16, the Company has entered into a Technical Services Agreement with Glencore whereby the Company reimburses Glencore for NorthMet technical support costs requested under an agreed scope of work, primarily in detailed project design and mineral
processing. During the twelve months ended December 31, 2018, the Company recorded $0.070 million (eleven months ended December 31, 2017 - $nil) for services under this agreement.

between 2019 and 2038, except for US state non-capital loss carry forwards which expire between 2019 and 2033. The Company is not recognizing these deferred tax assets because they relate to entities with a history of losses and
there is not convincing evidence that future taxable income will enable timely offset.

144,965 Fair Value Measurements The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest
priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described
below:
Level 1 –
Quoted prices (unadjusted) in active markets for identical assets or liabilities.
Level 2 –
Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly.
Level 3 –
Inputs for the asset or liability that are not based on observable market data.
The only financial instruments measured at fair value subsequent to recognition is the EIP receivable (see Note 5) which is measured at fair value through profit or loss using Level 3 inputs resulting
in a carrying value of $1.912 million (December 31, 2017 - $2.883 million) and an amount classified within accounts payable and accruals representing expected payments to settle restricted share units measured at fair value through profit or loss
using Level 2 inputs resulting in a carrying value of $0.371 million (December 31, 2017 - $0.439 million). The fair values of cash and restricted cash deposits, other current amounts receivable, and accounts payable and accruals Risks Arising from Financial Instruments and Risk Management The Company’s activities expose it to a variety of financial risks: market risk (including currency and interest rate), credit risk, and
liquidity risk. Reflecting the current stage of development of the Company’s NorthMet Project, the overall risk management program focuses on facilitating the Company’s ability to continue as a going concern and seeks to minimize potential adverse
effects on the Company’s ability to execute its business plan. Risk management is the responsibility of executive management. Material risks are identified and monitored and are discussed with the
Audit Committee and the Board of Directors. Currency Risk The Company incurs expenditures in Canada and the United States. The functional and reporting currency of the Company and its subsidiary
is the U.S. dollar. Foreign exchange risk arises because the amount of Canadian dollar cash, amounts receivable, or accounts payable and accruals will vary in U.S. dollar terms due to changes in exchange rates. As the majority of the Company’s expenditures are in U.S. dollars, the Company has kept a significant portion of its cash in U.S.
dollars. The Company has not hedged its exposure to currency fluctuations as the exposure to currency risk is currently insignificant. Interest Rate Risk Interest rate risk arises from interest paid on floating rate debt and interest received on cash and liquid short-term deposits. The
Company has not hedged any of its interest rate risk. The Company currently capitalizes to qualifying assets the majority of interest charges, and therefore the risk exposure is primarily on cash interest payable and net earnings in relation to the
subsequent depreciation of capitalized interest charges. The Company was exposed to interest rate risk through the following assets and liabilities:

24,143
$
6,931
Convertible debt
56,984
49,067
Non-convertible debt
$
178,483
$
92,268 Based on the above net exposures, as at December 31, 2018, a 1% change interest rates would have impacted the Company’s loss by
approximately $0.241 million and carrying value of convertible and non-convertible debt by approximately $2.355 million. Credit Risk Credit risk arises on cash and restricted cash deposits held with banks and financial institutions, as well as credit exposure on
outstanding amounts receivable. The maximum exposure to credit risk is equal to the carrying value of the financial assets of $26.735 million. The Company’s cash and restricted cash deposits are primarily held through large Canadian and United States financial institutions. Liquidity Risk Liquidity risk is the risk the Company will not be able to meet its financial obligations as they become due and arises through the excess
of financial obligations over available financial assets due at any point in time. The Company’s objective in managing liquidity risk is to maintain sufficient readily available reserves in order to meet its liquidity requirements at any point in
time and is achieved by maintaining sufficient cash and managing convertible and non-convertible debt. See additional discussion in Note 1. Capital Management The Company’s capital management objective is to safeguard the Company’s ability to continue as a going concern in order to pursue the
development of its mineral property. In the management of capital, the Company includes the components of shareholders’ equity, convertible debt and non-convertible debt. The Company manages the capital structure and makes adjustments to it
depending on economic conditions and the rate of anticipated expenditures. To maintain or adjust the capital structure, the Company may attempt to issue new shares, issue new debt, acquire or dispose of assets. The Company has no externally imposed
capital requirements. Although the Company expects to have the necessary resources to carry out its plans and operations through December 31, 2019, it does not
currently have sufficient capital to complete the development of NorthMet and generate future profitable operations and is in discussions to arrange sufficient capital to meet these requirements. During the upcoming fiscal year, the Company’s
objective is to identify the source or sources from which it will obtain the capital required to complete the Project. See additional discussion in Note 1.

States (“U.S.”) dollars unless otherwise specified.
Change in Accounting Policiesc) Change in Accounting Policies On January 1, 2018, the Company adopted the following new accounting standards that were previously issued by the IASB. Certain other new
standards and interpretations have been issued and were effective as of January 1, 2018 but did not have a material impact on the Company’s financial statements and are therefore not discussed below. The accounting policies discussed below reflect the Company’s adoption of IFRS 9 - Financial Instruments, effective January 1, 2018, and
IFRS 16 - Leases, which had an effective date of January 1, 2019 but for which the company early adopted as of January 1, 2018. For the eleven months ended December 31, 2017, the Company applied policies based on IAS 39 and IAS 17 and the effects of
the transition from IAS 39 to IFRS 9 and from IAS 17 to IFRS 16 are described below. IFRS 9 – Financial Instruments IFRS 9 addresses the classification, measurement and recognition of financial assets and financial liabilities. This standard replaces
parts of IAS 39 - Financial Instruments: Recognition and Measurement. The Company adopted IFRS 9 effective January 1, 2018 on a retrospective basis without restating prior period comparatives. IFRS 9 requires financial assets to be classified into the following measurement categories: fair value through profit and loss, fair
value through other comprehensive income, and those measured at amortized cost. The determination is made at initial recognition. On transition, the EIP receivable (see Note 5) previously classified as available-for-sale and measured at fair value
through other comprehensive income was re-classified as fair value through profit or loss with changes in fair value recognized in the statement of loss instead of through other comprehensive loss. Adoption resulted in re-classification of $0.210
million to the opening deficit from accumulated other comprehensive loss for cumulative gains on the EIP receivable. The following table shows the original measurement categories under IAS 39 and the new measurement categories under IFRS 9 for the
Company’s financial assets as at January 1, 2018:
Financial assets
2017 classification under IAS 39
2018 classification under IFRS 9
Cash
Loans and receivable
Amortized cost

Fair value through profit or loss IFRS 16 – Leases IFRS 16 replaces IAS 17 – Leases. The new standard requires capitalization of certain leases by the leasee and results in accounting
treatment similar to finance leases under IAS 17 - Leases. Exemptions for leases of very low value or short duration leases are applicable. The new standard results in an increase in lease assets and liabilities for the lessee. Under the new standard
the treatment of all lease expenses is aligned in the statement of earnings with depreciation, and an interest expense component recognized for each lease, in line with finance lease accounting under IAS 17 - Leases. The Company early adopted IFRS 16 effective January 1, 2018 on a modified retrospective basis without restating prior period
comparatives. As a result, the Company recorded a $0.211 million lease asset and corresponding lease liability for the one qualifying office lease that has been recognized over the remaining term. The Company’s other leases (see Note 3) are leases
to explore mining rights, which are excluded from IFRS 16’s scope. The following table summarizes the impact of adopting IFRS 9 - Financial Instruments and IFRS 16 - Leases:

Critical Accounting Estimatesd) Critical Accounting Estimates The preparation of consolidated financial statements in conformity with IFRS requires the use of certain critical accounting estimates.
These critical accounting estimates require management to make estimates that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as at the date of the financial statements. Critical accounting estimates used in the preparation of the consolidated financial statements are as follows: Determination of mineral reserves Reserves are estimates of the amount of product that can be economically and legally extracted from the Company’s property. In order to
estimate reserves, estimates are required about a range of geological, technical and economic factors, including quantities, production techniques, production costs, capital costs, transport costs, demand, prices and exchange rates. Estimating the
quantity of reserves requires the size, shape and depth of deposits to be determined by analyzing geological data. This process may require complex and difficult geological judgments to interpret the data. In addition, management will form a view of
forecast sales prices, based on current and long-term historical average price trends. Changes in the proven and probable reserves estimates may impact the carrying value of property, plant and equipment, rehabilitation provisions, recognition of
deferred tax amounts and depreciation, depletion and amortization. Provision for Environmental Rehabilitation Costs Provisions for environmental rehabilitation costs associated with mineral property, plant and equipment, are recognized when the Company
has a present legal or constructive obligation that can be estimated reliably, and it is probable an outflow of economic benefits will be required to settle the obligation. Provisions are determined by discounting the expected future cash flows at a
pre-tax risk-free rate that reflects current market assessments of the time value of money. The Company’s estimates of its ultimate environmental rehabilitation liabilities could be affected by changes in regulations, changes in
the extent of environmental rehabilitation required, changes in the means of rehabilitation, changes in the extent of responsibility for the financial liability, changes in operating plans, or changes in cost estimates. The operations of the Company
may in the future be affected from time to time in varying degrees by changes in environmental regulations, including those for future removal and site restoration costs. Both the likelihood of new regulations and their overall effect upon the
Company may vary greatly and are not predictable. The Company’s provision for environmental rehabilitation cost obligations represents management’s best estimate of the present value of
the future cash outflows required to settle the liability. See additional discussion in Note 6.
Critical Accounting Judgmentse) Critical Accounting Judgments The preparation of consolidated financial statements in conformity with IFRS requires the use of certain critical accounting judgments.
These critical accounting judgments require management to make judgments that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as at the date of the financial statements. Critical accounting judgments used in the preparation of the consolidated financial statements are as follows: Impairment of non-financial assets The carrying
amounts of the Company’s non-financial assets, including mineral property, plant and equipment, and intangible are reviewed
at each reporting date or when events or changes in circumstances occur that indicate the asset may not be recoverable to determine
whether there is any indication of impairment. If any such indication exists, the asset’s recoverable amount is estimated
at the greater of its value in use and its fair value less costs of disposal. In assessing value in use, the estimated future
cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the
time value of money and the risks specific to the asset. An impairment loss is recognized if the carrying amount of an asset
exceeds its estimated recoverable amount. An impairment loss previously recorded is reversed if there has been a change
in the estimates used to determine the recoverable amount resulting in an increase in the estimated service potential of an asset. The Company considers both external and internal sources of information in assessing whether there are any indications of impairment.
External sources of information the Company considers include changes in the market, economic, and legal environment in which the Company operates that are not within its control and affect the recoverable amount. Internal sources of information the
Company considers include indications of economic performance of the asset. The carrying value of mineral property, plant, and equipment, and intangible at the balance sheet date are described in Notes 4 and 5,
respectively. No impairment indicators were identified on the mineral property, plant and equipment or intangible for the twelve months ended December 31, 2018 or eleven months ended December 31, 2017. Going concern assumptions The Company must assess its ability to continue as a going concern and prepare financial statements on a going concern basis unless it
either intends to liquidate or cease trading or has no realistic alternative but to do so. In assessing whether the going concern assumption is appropriate, the Company takes into account all available information about the future, which is at
least, but is not limited to, twelve months from the end of the reporting period.
Cash and Cash Equivalents and Restricted Cash Depositsf) Summary of Significant Accounting Policies Cash and Cash Equivalents and Restricted Cash Deposits The Company considers cash and cash equivalents to include amounts held in banks and highly liquid investments with original maturities of
three months or less. Restricted Cash Deposits are held in a trust account and invested in highly liquid investments with a major financial institution as security and collateral for reclamation activities.
Financial AssetsFinancial Assets All financial assets are initially recorded at fair value and designated upon inception as one of the following categories: amortized cost
or fair value through profit or loss (“FVTPL”). Financial assets classified as FVTPL are measured at fair value with gains and losses recognized through profit and loss. Financial assets classified as amortized cost are measured at amortized cost
using the effective interest method less any allowance for impairment. The effective interest method is a method of calculating the amortized cost of a financial asset and of allocating interest income over the relevant period. The effective
interest rate is the rate that discounts estimated future cash receipts through the expected life of the financial asset, or, where appropriate, a shorter period. The Company recognizes loss allowances for Expected Credit Losses (“ECL”) for amounts
receivable not measured at FVTPL. Loss allowances for amounts receivable are measured at an amount equal to lifetime ECL. ECL is a probability-weighted estimate and measured as at the present value of all cash shortfalls including the impact of
forward looking information. The loss allowance is presented as a deduction to amounts receivable. Transaction costs associated with FVTPL financial assets are expensed as incurred, while transaction costs associated with amortized cost financial
assets are included in the initial carrying amount of the asset. See additional discussion in Note 15.
Mineral PropertyMineral Property Exploration and evaluation costs incurred prior to a Definitive Feasibility Study (“DFS”) are expensed as incurred. Development costs
incurred subsequent to a DFS and mineral property acquisition costs are capitalized until the property is placed into production, sold, allowed to lapse or abandoned. As a result of the DFS, NorthMet entered the development stage effective October 1,
2006. The Company has capitalized development expenditures related to NorthMet from that date. Upon commencement of production, related property acquisition and development costs are amortized on a unit of production basis over the
estimated proven and probable mineral reserves not to exceed the assets’ useful lives.
Plant and EquipmentPlant and Equipment Plant and equipment are recorded at historical cost less accumulated depreciation and if applicable, accumulated impairment losses.
Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, if it is probable that the future economic benefits of the expenditure will flow to the Company and its cost can be measured reliably.
The carrying amount of a replaced part is derecognized. All other repairs and maintenance are charged to the statement of loss and comprehensive loss during the period in which they are incurred. Depreciation of plant and equipment is calculated using the cost of the asset, less its residual value, over the estimated useful life of
the asset on a unit of production or straight-line basis, as appropriate.
LeasesLeases The Company recognizes a right-of-use asset and a lease liability at the lease commencement date. The right-of-use asset is initially
measured at cost, which comprises the initial amount of the lease liability, plus any initial direct costs incurred and an estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset or the site on which it is
located, less any lease incentives received. The right-of-use asset is subsequently depreciated using the straight-line method from the commencement date to the earlier of the end of the useful life of the right-of-use asset or the end of the lease
term. The lease liability is initially measured at the present value of the lease payments, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Company’s incremental borrowing rate. Generally,
the Company uses its incremental borrowing rate as the discount rate.
IntangibleIntangible Intangible costs and related acquisition costs are capitalized until the wetland credits are used, sold, or abandoned. Wetland credits
are used to offset and mitigate wetlands disturbed during construction and operation of NorthMet. As such, costs will be transferred to Mineral Property, Plant and Equipment once placed into service and
amortized on a unit of production basis over the estimated proven and probable mineral reserves not to exceed the assets’ useful lives. See additional discussion in Note 5.
Financial LiabilitiesFinancial Liabilities All financial
liabilities are initially recorded at fair value and designated upon inception as FVTPL or other financial liabilities.
Financial liabilities classified as FVTPL are initially recognized at fair value with directly attributable transaction costs
expensed as incurred. At the end of each reporting period, financial liabilities at FVTPL are measured at fair value, with
changes in fair value recognized directly in profit or loss in the period in which they arise. Financial liabilities classified
as other financial liabilities are initially recognized at fair value less directly attributable transaction costs and subsequently
measured at amortized cost using the effective interest method which calculates the amortized cost of a financial liability and
allocates interest expense over the expected life of the financial liability. Exchanges of instruments and modifications to debt are assessed using quantitative and qualitative factors to consider whether the
exchange or modification constitutes an extinguishment of the original financial liability and establishment of a new financial liability. In the case of extinguishment, any fees or costs incurred are recognized in profit or loss in the period in
which they arise. Where the terms in an exchange or modification are not assessed to be substantially different, a modification gain or loss is recognized at an amount equal to the difference between the modified cash flows discounted at the
original effective interest rate and the carrying value of the debt. The carrying value of the debt is adjusted for this modification gain or loss, directly attributable transaction costs, and any cash paid to or received from the debt holder. See
additional discussion in Note 15.
Borrowing costsBorrowing costs Borrowing costs directly attributable to the acquisition, construction or production of a qualifying asset are capitalized as part of the
cost of that asset until such time as the asset is substantially complete and ready for its intended use or sale. Where funds have been borrowed specifically to finance an asset, the amount capitalized is the actual borrowing costs incurred. Where
the funds used to finance an asset form part of general borrowings, the amount capitalized is calculated using a weighted average of rates applicable to relevant borrowings of the Company during the period. Other borrowing costs not directly
attributable to a qualifying asset are expensed in the year incurred. Classification in the cash flow statement is in accordance with the classification of the underlying asset to which those payments were capitalized.
Share-Based CompensationShare‑Based Compensation All share-based compensation awards made to directors, employees and non-employees are measured and recognized using a fair value based
method. For directors and employees, or those providing services similar to employees, the fair value of options is determined using the Black-Scholes pricing model. The fair value of the bonus shares, restricted shares, and restricted share units
expected to be settled in shares are calculated using the intrinsic value of the shares at issuance and is amortised over the vesting period. For awards expected to be settled in cash, the change in market value and corresponding liability is
adjusted to fair value at each reporting period. The award is accrued and charged over the vesting period either to operations or mineral property plant and equipment, with the offsetting
credit to equity reserves for equity settled awards or liabilities for cash settled awards. If and when share options are ultimately exercised or bonus shares, restricted shares, and restricted share units vest, the applicable amounts are
transferred to share capital or removed from liabilities. Certain awards vest upon achievement of non-market performance conditions. On a quarterly basis, management assesses the probability of
achieving those performance conditions using the best available information and estimates the appropriate vesting period. When the Company amends the terms of share options, the incremental change in the fair value of the options due to the amendment, as
determined using the Black-Scholes pricing model, is recognized over the vesting period in the statement of loss or capitalized as appropriate.
Share Purchase WarrantsShare Purchase Warrants The Company issues share purchase warrants in connection with certain financing transactions. The fair value of the warrants, as
determined using the Black-Scholes pricing model or fair value of goods or services received, is credited to equity reserves. The recorded value of share purchase warrants is transferred to share capital upon exercise.
Foreign Currency TranslationForeign Currency Translation The U.S. dollar is the functional currency of the Company and its wholly-owned subsidiary. Amounts in the consolidated financial
statements are expressed in U.S. dollars unless otherwise stated. Transactions in foreign currencies are translated into the functional currency at the exchange rates at the date of the transactions. Monetary assets and liabilities of the Company’s
operations denominated in a currency other than the U.S. dollar are translated using exchange rates prevailing at the balance sheet date. Revenue and expense items are translated at the exchange rates in effect at the date of the underlying
transaction. Exchange differences are recognized in net loss in the year in which they arise.
Loss Per ShareLoss Per Share Loss per share is computed by dividing the loss for the year by the weighted average number of common shares outstanding during the year.
Basic and diluted loss per share for each year presented are the same due to the effect of potential issuances of shares under warrant or share option agreements being, in total, anti-dilutive.
Income Taxes and Deferred TaxesIncome Taxes and Deferred Taxes The income tax expense or benefit for the year consists of two components: current and deferred. Current tax is the expected tax payable or receivable on the taxable profit or loss for the year. Current tax is calculated using tax
rates and laws that were enacted or substantively enacted at the balance sheet date in each of the jurisdictions and include any adjustments for taxes payable or recovery in respect of prior periods. Taxable profit or loss differs from profit or loss as reported in the Consolidated Statements of Loss and Comprehensive Loss because of
items of income or expense that are taxable or deductible in other years, and items that are never taxable or deductible. Deferred tax is recognized on temporary differences between the carrying amounts of assets and liabilities in the financial statements and
the corresponding tax basis used in the computation of taxable profit. Deferred tax liabilities are generally recognized for all taxable temporary differences not eligible for offset. Deferred tax assets are generally recognized for all deductible
temporary differences, loss carry forwards and tax credit carry forwards to the extent that it is probable that taxable profits will be available against which they can be utilized. To the extent that the Company does not consider it to be probable
that taxable profits will be available against which deductible temporary differences, loss carry forwards, and tax credit carry forwards can be utilized, a deferred tax asset is not recognized.
