The Company notes that a preliminary economic assessment is preliminary in nature, it includes inferred mineral resources that are considered too speculative geologically to have economic consideration applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized.

(1) Non-IFRS Financial Measures

The Company has included certain non-IFRS measures in this document as discussed below. The Company believes that these measures, in addition to conventional measures prepared in accordance with IFRS, provide investors an improved ability to evaluate the underlying performance of the Company. The 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.

Cash cost ("Cash cost") per ounce

Cash cost per ounce is a non-IFRS measure. In the gold mining industry, this metric is a common performance measure that does not have a standardized meaning under IFRS. Cash costs include direct costs (including smelting, refining, transportation and selling costs), royalties and production taxes, general and administration costs and changes in finished goods inventory.

All-in sustaining costs ("AISC") per ounce

AISC per ounce is a non-IFRS measures. This metric is intended to assist readers in evaluating the total cost of producing gold from operations. While there is no standardized meaning across the industry for AISC measures, the Company's definition conforms to the definition of AISC as set out by the World Gold Council. The Company defines AISC as the cash operating costs (as defined above), reclamation cost accretion, mine site expensed exploration, and sustaining capital expenditures. For the purpose of the PEA, AISC does not include corporate general and administration costs or mine site expensed exploration.

Free cash flow

In the mining industry, free cash flow is a common performance measure with no standardized meaning. The Company calculates free cash flow by deducting cash capital spending (capital expenditures, net of expenditures paid through finance leases) from net cash provided by operating activities. The Company discloses free cash flow as it believes the measure provides valuable assistance to investors and analysts in evaluating the Company's ability to generate cash flow after capital investments and build the cash resources of the Company.
