NON-IFRS FINANCIAL MEASURES

The Company has included AISC per ounce of gold sold, a Non-IFRS financial ratio, in this press release, which is described below.

All-in Sustaining Costs per ounce of gold sold

The objective of AISC is to provide stakeholders with a key indicator that reflects as close as possible the full cost of producing and selling an ounce of gold. AISC per ounce of gold sold is a Non-IFRS ratio that is intended to provide investors with transparency regarding the total costs of producing one ounce of gold in the relevant period.

The Company reports AISC per ounce of gold sold on a by-product basis. The methodology for calculating AISC per ounce of gold sold is set out below and is consistent with the guidance methodology set out by the World Gold Council. The World Gold Council definition of AISC seeks to extend the definition of total Cash Cost by deducting administrative expenses, cost of sales of non-mining operations, sustaining exploration, sustaining leases and leaseback, and sustaining capital expenditures. Non-sustaining costs are primarily those related to new operations and major projects at existing operations that are expected to materially benefit the current operation. The determination of classification of sustaining versus non-sustaining requires judgment by management. AISC excludes current and deferred income tax payments, finance expenses and other expenses. Consequently, these measures are not representative of all of the Company's cash expenditures. In addition, the calculation of AISC does not include depreciation and amortization cost or expense as it does not reflect the impact of expenditures incurred in prior periods. Therefore, it is not indicative of the Company's overall profitability. Other companies may quantify these measures differently because of different underlying principles and policies applied. Differences may also occur due to different definitions of sustaining versus non-sustaining.

For a discussion of the use of Non-IFRS financial measures and a reconciliations thereof to the most directly comparable IFRS measures, please refer to the Company's most recent MD&A filed under the Company's profile and available on SEDAR+ at www.sedarplus.ca.

_______________________________

1 AISC per ounce of gold sold is a non-IFRS ratio, with no standardized meaning under IFRS, and therefore may not be comparable to similar measures presented by other issuers. For further information, see Non-IFRS Financial Measures in this news release.
