Technical Reports and Qualified Persons This presentation includes disclosure of scientific and technical information concerning the Goldsky mineral projects from technical reports ("technical reports") prepared in accordance with Canadian NI 43- 101- Standards of Disclosure for Mineral Projects ("NI 43-101"). The technical reports, which are described below, are available on SEDAR+(www.sedarplus.ca) under Goldsky’s profile or that of its wholly-owned subsidiaries, Mawson and Gold Line Resources Ltd., as applicable. Readers are cautioned to review the following technical reports in full: • For further information regarding the Barsele project, reference should be made to the following NI 43 - 101technical report titled "Amended NI 43-101Technical Report and Mineral Resource Estimate for the Barsele Project” with an effective date of February 21, 2019 and a signature date of December 16, 2020 prepared. • For further information regarding the Kylmäkangas project, reference should be made to the following NI 43-101 technical report titled "NI 43-101 technical report and mineral resource estimate for the KylmäkangasGold Project" with an effective date of July 25, 2022 . • For further information regarding the Langtjärn project, reference should be made to the following NI 43-101 technical report titled "NI 43- 101 technical report and mineral resource estimate for the Längtjärn property" with an effective date of June 30, 2020 . • For further information regarding the Rajapalot Gold-Cobalt project, reference should be made to the following NI 43-101 technical report titled “NI 43-101 Technical Report on a Preliminary Economic Assessment of the Rajapalot Gold-Cobalt Project, Finland” with an effective date of December 19, 2023. The technical and scientific information in this presentation was reviewed, prepared, and approved by Benjamin Gelber, a practicing Professional Geologist (P.Geo) registered with Engineers & Geoscientists British Columbia (EGBC, Licence No. 33258), who is a “Qualified Person” as defined by National Instrument 43-101– Standards of Disclosure for Mineral Projects (“NI 43-101”). Mineral Resources This release contains references to estimates of Mineral Resources. The estimation of mineral resources is inherently uncertain and involves subjective judgments about many relevant factors. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The accuracy of any such estimates is a function of the quantity and quality of available data, and of the assumptions made and judgments used in engineering and geological interpretation, which may prove to be unreliable and depend, to a certain extent, upon the analysis of drilling results and statistical inferences that may ultimately prove to be inaccurate. Mineral resource estimates may require re-estimation based on, among other things: (i) fluctuations in the price of gold, silver and other metals; (ii) results of drilling; (iii) results of metallurgical testing, process and other studies; (iv)changes to proposed mine plans; (v)the evaluation of mine plans subsequent to the date of any estimates; and (vi) the possible failure to receive required permits, approvals and licenses. These mineral resource estimates include inferred mineral resources that are normally considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is also no certainty that these inferred mineral resources will be converted to measured and indicated categories through further drilling, or into mineral reserves, once economic considerations are applied. Forward-Looking Statements Certain statements in this presentation are "forward-looking statements", including within the meaning of applicable laws. All statements other than statements of historical fact included in this presentation, including, statements regarding the effect of the Transaction on Goldsky's resources, gold grades, metallurgies, business, prospects, operations and future plans and objectives of Goldsky are forward- looking statements based on forecasts of future operational or financial results, estimates of amounts not yet determinable and assumptions of management that involve various risks and uncertainties, as well as Goldsky’s corporate strategies, including additional acquisitions, and plans for future exploration. Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions or future events or performance (often, but not always, using words or phrases such as "expects" or "does not expect", "is expected", "anticipates" or "does not anticipate", "plans", "estimates" or "intends", or stating that certain actions, events or results "may", "could", "would", "might", or "will" be taken, occur or be achieved) are not statements of historical fact and may be "forward-looking statements." Goldsky cautions that forward-looking statements involves known and unknown risks, uncertainties and other factors that may cause actual results, performance or achievements to be materially different from those expressed or implied by such information, including, but not limited to, failure to obtain the necessary regulatory and other approvals; gold and silver price volatility; fluctuations in foreign exchange rates and interest rates; the impact of any hedging activities; discrepancies between actual and estimated production, between actual and estimated reserves and resources or between actual and estimated metallurgical recoveries; capital expenditure requirements; and the success of exploration and permitting activities. Although Goldsky has attempted to identify important factors that could cause actual results, performance or achievements to differ materially from those contained in forward-looking statements, there can be other factors that cause results, performance or achievements not to be as anticipated, estimated or intended. There can be no assurance that such information will prove to be accurate or that management's expectations or estimates of future developments, circumstances or results will materialize. Accordingly, readers should not place undue reliance on forward-looking statements. Subject to any continuing obligations under applicable law or any relevant stock exchange listing rules, in providing this information, Goldsky does not undertake any obligation to publicly update or revise any of the forward-looking statements or to advise of any change in events, conditions or circumstances. Market Data Market data and other statistical information used throughout this presentation are based on internal research by Goldsky, independent industry publications, government publications, reports by market research firms or their published independent sources. Industry publications, governmental publications, market research surveys and forecasts generally state that the information contained therein has been obtained from sources believed to be reliable. Although Goldsky believes such information is accurate and reliable, neither has independently verified any of the data from third party sources cited or used for industry estimates used in this presentation, nor has Goldsky ascertained the underlying economic assumptions relied upon therein. While Goldsky believe internal estimates are reliable, such estimates have not been verified by any independent sources, and Goldsky makes no representations as to the accuracy of such estimates.
