(1) NON-IFRS FINANCIAL MEASURES

Calibre has included certain non-IFRS measures as discussed below. The Company believes that these measures, in addition to conventional measures prepared in accordance with IFRS, provide investors with an improved ability to evaluate the underlying performance of the Company. These non-IFRS measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. These measures do not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to other issuers.

TCC per Ounce of Gold : TCC include production costs, royalties, production taxes, refinery charges, and transportation charges. Production costs consist of mine site operating costs such as mining, processing, local administrative costs (including stock-based compensation related to mine operations) and current inventory write-downs, if any. Production costs are exclusive of depreciation and depletion, reclamation, capital and exploration costs. TCC are net of by-product silver sales and are divided by gold ounces sold to arrive at a per ounce figure.

AISC per Ounce of Gold : AISC is a performance measure that reflects the total expenditures that are required to produce an ounce of gold from current operations. While there is no standardized meaning of the measure across the industry, the Company's definition is derived from the definition as set out by the World Gold Council in its guidance dated June 27, 2013, and November 16, 2018, respectively. The World Gold Council is a non-regulatory, non-profit organization established in 1987 whose members include global senior mining companies. The Company believes that this measure is useful to external users in assessing operating performance and the ability to generate free cash flow from operations.

Calibre defines AISC as the sum of TCC, corporate general and administrative expenses (excluding one-time charges), reclamation accretion related to current operations and amortization of asset retirement obligations (“ARO”), sustaining capital (capital required to maintain current operations at existing production levels), lease repayments, and exploration expenditures designed to increase resource confidence at producing mines. AISC excludes capital expenditures for significant improvements at existing operations deemed to be expansionary in nature, exploration and evaluation related to resource growth, rehabilitation accretion not related to current operations, financing costs, debt repayments, and taxes. Total AISC is divided by gold ounces sold to arrive at a per ounce figure

Average Realized Price per Ounce Sold: Average Realized Gold Price Per Ounce Sold is intended to enable management to understand the average realized price of gold sold in each reporting period after removing the impact of non-gold revenues and by-produce credits, which in the Company's case are not significant, and to enable investors to understand the Company's financial performance based on the average realized proceeds of selling gold production in the reporting period. Average Realized Gold Price Per Ounce Sold is a common performance measure that does not have any standardized meaning. The most directly comparable measure prepared in accordance with IFRS is revenue from gold sales.

Adjusted Net Earnings : Adjusted Net Earnings and Adjusted Net Earnings Per Share - Basic exclude a number of temporary or one-time items considered exceptional in nature and not related to the Company's core operation of mining assets or reflective of recurring operating performance. Management believes Adjusted Net Earnings may assist investors and analysts to better understand the current and future operating performance of the Company's core mining business. Adjusted Net Earnings and Adjusted Net Earnings Per Share do not have a standard meaning under IFRS. They should not be considered in isolation, or as a substitute for measures of performance prepared in accordance with IFRS and are not necessarily indicative of earnings from mine operations, earnings, or cash flow from operations as determined under IFRS.

Cash From Operating Activities Before Changes in Working Capital : Cash from Operating Activities before Changes in Working Capital is a non-IFRS measure with no standard meaning under IFRS, which is calculated by the Company as net cash from operating activities less working capital items. The Company believes that Net Cash from Operating Activities before Changes in Working Capital, which excludes these non-cash items, provides investors with the ability to better evaluate the operating cash flow performance of the Company.

Net Debt and Adjusted Net Debt : The Company believes that in addition to conventional measures prepared in accordance with IFRS, the Company and certain investors and analysts use net debt to evaluate the Company's performance. Net debt does not have any standardized meaning prescribed under IFRS, and therefore it may not be comparable to similar measures employed by other companies. This measure is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performances prepared in accordance with IFRS. Net debt is calculated as the sum of the current and non-current portions of loans and borrowings, net of the cash and cash equivalent balance as at the balance sheet date. Adjusted Net Debt is calculated as Net Debt less fair value and other non-cash adjustments that will not result in a cash outflow to the Company. The Company believes that Adjusted Net Debt provides a better understanding of the Company's liquidity.

EBITDA and Adjusted EBITDA : The Company believes that certain investors use the EBITDA and the adjusted EBITDA (“Adjusted EBITDA”) measures to evaluate the Company's performance and ability to generate operating cash flows to service debt and fund capital expenditures. EBITDA and Adjusted EBITDA do not have a standardized meaning as prescribed under IFRS and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. The Company calculates EBITDA as earnings or loss before taxes for the period excluding depreciation and depletion and finance costs. EBITDA excludes the impact of cash costs of financing activities and taxes and the effects of changes in working capital balances and therefore is not necessarily indicative of operating profit or cash flow from operations as determined under IFRS. Adjusted EBITDA is calculated by excluding one-off costs or credits relating to non-routine transactions from EBITDA that are not indicative of recurring operating performance. Management believes this additional information is useful to investors in understanding the Company's ability to generate operating cash flow by excluding from the calculation these non-cash and cash amounts that are not indicative of the recurring performance of the underlying operations for the reporting periods.

Adjusted Net Debt to Adjusted EBITDA : The Adjusted Net Debt to Adjusted EBITDA measures provide investors and analysts with additional transparency about the Company's liquidity position, specifically, the Company's ability to generate sufficient operating cash flows to meet its mandatory interest obligations and pay down its outstanding debt balance in full at maturity. This measure is a Non-IFRS measure and it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. The calculation of Adjusted Net Debt is shown above.
