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 28, 2022 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 the PIL property relies on
disclosure from previous operators and has 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.
