Forward-Looking Statements

FORWARD-LOOKING STATEMENTS

This presentation contains forward-looking information. Forward looking information contained in this presentation includes, but is not limited to, statements with respect to: (i) the

estimation of inferred and indicated mineral resources; (ii) the success of exploration activities; (iii) the results of the PEA including statements about future production, future

operating and capital costs, the projected IRR, NPV, payback period, and production timelines for the Tiger Deposit.

These statements are based on information currently available to ATAC Resources Ltd. (“ATAC”) and ATAC provides no assurance that actual results will meet management’s

expectations. In certain cases, forward-looking information may be identified by such terms as "anticipates", "believes", "could", "estimates", "expects", "may", "shall", "will", or

"would". Forward-looking information contained in this presentation is based on certain factors and assumptions regarding, among other things, the estimation of mineral

resources, the realization of resource estimate, gold metal prices, the timing and amount of future exploration and development expenditures, the estimation of initial and

sustaining capital requirements, the estimation of labour and operating costs, the availability of necessary financing and materials to continue to explore and develop the Tiger

Deposit in the short and long-term, the progress of exploration and development activities, the receipt of necessary regulatory approvals, the completion of the environmental

assessment process, and assumptions with respect to currency fluctuations, environmental risks, title disputes or claims, and other similar matters. While ATAC considers these

assumptions to be reasonable based on information currently available to it, they may prove to be incorrect.

Forward-looking information involves known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of ATAC to be

materially different from any future results, performance or achievements expressed or implied by the forward-looking information. Such factors include risks inherent in the

exploration and development of mineral deposits, including risks relating to changes in project parameters as plans continue to be redefined including the possibility that mining

operations may not commence at the Tiger Deposit, risks relating to variations in mineral resources, grade or recovery rates resulting from current exploration and development

activities, risks relating to changes in gold prices and the worldwide demand for and supply of gold, risks related to increased competition in the mining industry generally, risks

related to current global financial conditions, uncertainties inherent in the estimation of mineral resources, access and supply risks, reliance on key personnel, operational risks

inherent in the conduct of mining activities, including the risk of accidents, labour disputes, increases in capital and operating costs and the risk of delays or increased costs that

might be encountered during the development process, regulatory risks, including risks relating to the acquisition of the necessary licenses and permits, financing, capitalization

and liquidity risks, including the risk that the financing necessary to fund the exploration and development activities at the Tiger Deposit may not be available on satisfactory terms,

or at all, risks related to disputes concerning property titles and interest, and environmental risks. This list is not exhaustive of the factors that may affect any of ATAC's forward-

looking information. These and other factors should be considered carefully and readers should not place undue reliance on ATAC's forward-looking information. ATAC does not

undertake to update any forward-looking information that may be made from time to time by ATAC or on its behalf, except in accordance with applicable securities laws.

TECHNICAL DISCLOSURE

It should be noted that the Tiger Deposit PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the

economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the PEA forecast will be realized or that any of

the resources will ever be upgraded to reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. Additional information about the

Tiger Deposit PEA is summarized in ATAC’s February 27, 2020 technical report titled “Technical Report and Preliminary Economic Assessment for the Tiger Deposit, Rackla Gold

Project, Yukon, Canada”, which can be viewed at www.sedar.com under the ATAC profile or on the ATAC website at www.atacresources.com. Additional information about the

Osiris Resource Estimate is summarized in ATAC’s July 2, 2018 technical report titled “Technical Report and Estimate of Mineral Resources for the Osiris Project, Yukon,

Canada,” which can be viewed at www.sedar.com under the ATAC profile or on the ATAC website at www.atacresources.com. Historical information for East Goldfield and the Val

Target rely on disclosure from previous operators and have not been independently verified.

QUALIFIED PERSON

Adam Coulter, M.Sc., P.Geo., ATAC’s Vice President of Exploration, is a qualified person for the purposes of National Instrument 43-101. All technical information contained in this

presentation has been approved by Adam Coulter.

TRUE WIDTHS

True widths for diamond drill holes are estimated to be 30% - 100% of intersected widths. RAB drill hole intersections are drilled thicknesses and true widths are unknown.
