uncertainties and contingencies. Many factors, both known and unknown, could cause actual results,

performance, or achievements to be materially different from the results, performance or achievements

that are or may be expressed or implied by such forward –looking statements or forward -looking

information and the Company has made assumptions and estimates based on or related to many of these

conduct of the Company's mining activities in foreign jurisdictions; regulatory, consent or permitting

delays; risks relating to reliance on the Company's management team and outside contractors; risks

regarding exploration and mining activities; the Company's inability to obtain insurance to cover all risks,

on a commercially reasonable basis or at all; currency fluctuations; risks regarding the failure to generate

sufficient cash flow from operations; risks relating to project financing and equity issuances; risks and

unknowns inherent in all mining projects, including the inaccuracy of reserves and resources, metallurgical

recoveries and capital and operating costs of such projects; contests over title to properties, particularly

title to undeveloped properties; laws and regulations governing the environment, health and safety; the

ability of the communities in which the Company operates to manage and cope with the implications of

public health crises; the economic and financial implications of public health crises, ongoing military

conflicts and general economic factors to the Company; operating or technical difficulties in connection

with mining or development activities; employee relations, labour unrest or unavailability; the Company's

interactions with surro unding communities; the Company's ability to successfully integrate acquired

assets; the speculative nature of exploration and development, including the risks of diminishing

quantities or grades of reserves; stock market volatility; conflicts of interest among certain directors and

officers; lack of liquidity for shareholders of the Company; litigation risk; and the factors identified under

the caption “Risk Factors” in the Company’s public disclosure documents. Readers are cautioned against

attributing undue certainty to forward–looking statements or forward-looking information. Although the

Company has attempted to identify important factors that could cause actual results to differ materially,

there may be other factors that cause results not to be anticipated, estimated or intended. The Company

does not intend, and does not assume any obligation, to update these forward –looking statements or

forward-looking information to reflect changes in assumptions or changes in circumstances or any other

events affecting such statements or information, other than as required by applicable law.

This news release includes certain non-International Financial Reporting Standards (IFRS) measures. The

Company has included these measures, in addition to conventional measures conforming with IFRS, to

provide investors with an improved ability to evaluat e the project and provide comparability between

projects. The non -IFRS measures, which are generally considered standard measures within the mining

industry albeit with non-standard definitions, 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. Cash costs (Cash Costs) are a common financial performance measure in the gold mining industry

but with no standard meaning under IFRS. The Company believes that, in addition to conventional

measures prepared in accordance with IFRS, certain investors use this information to evaluate each

project’s economic results in the technical reports and each project’s potential to generate operating

earnings and cash flow. All -in Sustaining Costs (AISC) more fully defines the total costs associated with

producing precious metals. The AISC is calculated based on guidelines published by the World Gold Council

(WGC), which were first issued in 2013. In light of ne w accounting standards and to support further

consistency of application, the WGC published an updated Guidance Note in 2018. Other companies may

calculate this measure differently because of differences in underlying principles and policies applied.

Differences may also arise due to a different defin ition of sustaining versus growth capital. Note that in

respect of AISC metrics within the technical reports because such economics are disclosed at the project

level, corporate general and administrative expenses were not included in the AISC calculations.
