FORWARD-LOOKING STATEMENTS

Cautionary Note Regarding Forward Looking Information:

This website includes “forward-looking statements” and “forward-looking information” (collectively, “forward-looking statements”) within the meaning of Canadian securities legislation, which reflect the Apollo’s current expectations regarding the future results of operations, performance, and achievements. All statements included in this website, other than statements of historical fact, are forward-looking statements including, without limitation, statements with respect to the potential of the Calico Project and the Cinco de Mayo Project (the “Projects”); the potential for identification of gold and barite resources at the Calico Project; the potential to expand the Calico Project resource estimate and upgrade its confidence level, including prospective mineralization on strike and at depth; obtaining social license to operate at Cinco de Mayo Project; the potential to produce and update the resource estimate at the Cinco de Mayo Project; future silver recoveries; expected timing, commencement and results of future drilling or exploration activity at the Projects; the expected timing and completion of further economic studies; the estimation of mineral resources and reserves; the realization of mineral resource estimates; and the realization of mineral recovery estimates. Forward-looking statements include predictions, projections and forecasts and are often, but not always, identified by the use of words such as “anticipate”, “believe”, “plan”, “estimate”, “expect”, “potential”, “target”, “budget” and “intend” and statements that an event or result “may”, “will”, “should”, “could” or “might” occur or be achieved and other similar expressions and includes the negatives thereof. Forward-looking statements are based on the reasonable assumptions, estimates, analysis and opinions of the management of the Company made in light of its experience and its perception of trends, current conditions and expected developments, as well as other factors that management of the Company believes to be relevant and reasonable in the circumstances at the date that such statements are made. Forward-looking information is based on reasonable assumptions that have been made by the Company as at the date of such information and is subject to known and unknown risks, uncertainties and other factors that may have caused actual results, level of activity, performance or achievements of the Company to be materially different from those expressed or implied by such forward-looking information, including but not limited to: risks associated with mineral exploration and development; possible variations in mineral resources, grade or recover rates; fluctuations in metal and mineral prices; general economic conditions, including risks related to macro-economic and global financial conditions; inflation; availability of capital; accuracy of the Company’s projections and estimates; realization of mineral resource estimates, interest and exchange rates; competition; financing and share price fluctuations; fluctuations in market prices of mining consumables and availability of other goods or services required for the current or future work program; capital expenditures; ; actual results of current exploration activities; changes in national and local government regulation of mining operations, tax rules and regulations, and political and economic developments in the United States of America and Mexico; environmental risks; limitations on insurance; competition; limitations on the ability to acquire and integrate new properties or businesses; the ability to obtain governmental permits and/or approvals in a timely manner; regulatory risks; conflicts of interest; the ability to retain key personnel; foreign operations; community relations; litigation, climate change; operating or technical difficulties in connection with development activities; personnel relations; contests over title to properties; changes in project parameters as plans continue to be refined; fluctuations in foreign currency exchange rates; information technology; the unknown impact related to potential business disruptions stemming from the COVID-19 outbreak, or other infectious illnesses, current ongoing and future global conflicts and other risks of the mining industry. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues. The quantity and grade of reported inferred mineral resources in this estimation are uncertain in nature and there has been insufficient exploration to define these inferred mineral resources as an indicated or measured mineral resource and it is uncertain if further exploration will result in upgrading them to an indicated or measured mineral resource category. Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that any mineral resource will be converted into a mineral reserve. Forward-looking statements are based on assumptions management believes to be reasonable, including but not limited to the price of silver, gold and barite; the demand for silver, gold and barite; the ability to carry on exploration and development activities; the timely receipt of any required approvals; the ability to obtain qualified personnel, equipment and services in a timely and cost-efficient manner; the ability to operate in a safe, efficient and effective matter; the ability to access capital when required; and the regulatory framework regarding environmental matters, and such other assumptions and factors as set out herein. Although the Company has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking information, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that forward-looking statements will prove to be accurate and actual results, and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking information contained herein, except in accordance with applicable securities laws. The forward-looking information presented herein aims to assist investors in understanding the Company’s expected financial and operational performance, as well as its plans and objectives. It may not be suitable for other purposes. The Company does not undertake to update any forward-looking information, except in accordance with applicable securities laws.

Information Concerning Calico Resource Estimate:

Cautionary Note for Mineral Resource Estimates The Calico Silver Project 2023 Mineral Resource Estimate (“2023 MRE”) has been prepared by Derek Loveday, P. Geo., of Stantec Consulting Services Ltd. (“Stantec”), an independent Qualified person, in co-operation with Mariea Kartick, P.Geo., (also of Stantec, and an independent Qualified Person for drilling data QA/QC) and Eric Hill, P.E., PMP (previously of Samuel Engineering Inc., an independent Qualified Person for metallurgical test work) in conformance with the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) “Estimation of Mineral Resource and Mineral Reserves Best Practices” guidelines and are reported in accordance with the Canadian Securities Administrators National Instrument (“NI”) 43-101. Please see news release dated March 6, 2023, for more information on the 2023 MRE. Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that any mineral resource will be converted into a mineral reserve. For all references to the 2023 MRE included herein, Please note that: The MRE is represented by the base-case estimate. • Ounces are reported as troy ounces. CIM definitions are followed for classification of the mineral resource. For the Waterloo Property, cut-off grade was calculated using the following variables: surface mining operating costs (US$2.75/st), processing costs (US$20.00/st), general and administrative costs (US$3/st), silver price (US$23.50/oz), gold price (US$1,800/ oz), and metal recoveries (silver 65%, gold 80%). Resources reported are constrained to within a conceptual economic pit shell targeting mineralized blocks with a minimum of 50 ppm (50 g/t) silver and 0.3 ppm (0.30 g/t) gold. Specific gravity for the mineralized zone is fixed at 2.44 t/m3 (13.13 ft3/st). Silver grade was capped at 450 g/t and gold was capped at 2 g/t for the Waterloo estimate only. No drilling was completed on the Langtry Property since the declaration of the 2022 MRE and as such, the Inferred mineral resource announced February 9, 2022, for the Langtry Property remains unchanged and current. The 2022 MRE was prepared by Derek Loveday, P. Geo. of Stantec, an independent Qualified Person. Cut-off grade for the Langtry 2022 MRE was calculated using surface mining operating costs of US$2.50/st, processing costs of US$29.00/st, silver price of US$23.00/oz and silver recovery of 80%. The Langtry resource is constrained to within a conceptual economic pit shell targeting mineralized blocks with a minimum of 50 ppm (50 g/t) silver. Please refer to news release dated February 9, 2022 for more information on the 2022 MRE. Totals may not represent the sum of the parts due to rounding. 

Information Concerning Cinco de Mayo Historical Resource Estimates:

Source of the historical estimate: Upper Manto Deposit: In 2012, MAG Silver reported at an NSR cut-off of US$100/t, an Inferred Mineral Resource for total 12.45 million tonnes of 132 g/t Ag, 0.24 g/t Au, 2.86% Pb, and 6.47% Zn. The total contained metals in the historical resource were 52.7 million ounces of Ag, 785 million pounds of Pb, 1,777 million pounds of Zn, and 96,000 ounces of Au. The Upper Manto Deposit historical mineral resource estimate (2012) was prepared by David Ross, M.Sc., P.Geo., of RPA, an independent Qualified Person from MAG Silver. The 2012 Technical Report had an effective date of September 1, 2012. This Technical Report conformed to NI 43-101 Standards of Disclosure for Mineral Projects. Please see MAG Silver news release dated October 12, 2012, for more information on the 2012 MRE. In addition, the reader is directed to the NI-43-101 that was filed by MAG Silver on SEDAR+. Pozo Seco Deposit: In 2010, MAG Silver reported at a cut-off grade of 0.022% Mo, an Indicated Mineral Resource for a total of 29.1 million tonnes grading 0.147% Mo and 0.25 g/t Au and containing 94.0 million pounds Mo and 230,000 ounces of Au. In addition, the Inferred Mineral Resource was estimated at 23.4 million tonnes grading 0.103% Mo and 0.17 g/t Au, containing 53.2 million pounds Mo and 129,000 ounces Au. The Pozo Seco Mineral Resource Estimate (2010) was prepared by David Ross, M.Sc., P.Geo., of RPA, an independent Qualified Person from MAG Silver. The 2010 Technical Report had an effective date of July 12, 2010. This Technical Report conformed to the NI 43-101 Standards of Disclosure for Mineral Projects. Please see MAG Silver news release dated August 4, 2010, for more information on the 2010 MRE. In addition, the reader is directed to the NI-43-101 that was filed by MAG Silver on SEDAR+. Key assumptions and method used: Upper Manto Deposit: For the Cinco de Mayo, Upper Manto Deposit, the 2012 Historical Mineral Resource was estimated at an NSR cut-off value of US$100 per tonne. NSR values were calculated in US dollars using factors: Ag ( $0.60 per g/t), Au ( $12.32 per g/t), Pb ($18.63 per %) and Zn ($14.83 per %). These factors were based on metal prices of US$27.00/oz Ag, US$1,500/oz Au, $1.15/lb Pb, and $1.20/lb Zn and estimated recoveries and smelter terms. The values were capped to 1,000 g/t Ag, 4 g/t Au, 18% Pb, and 24% Zn. Grade interpolations for Ag, Au, Pb, Zn, and density were made using inverse distance cubed (ID3 ). The resource was reported in-situ. Pozo Seco Deposit: For the Pozo Seco Deposit, the 2010 Historical Mineral Resource estimate was estimated at a cut-off grade of 0.022% Mo. The cut-off grade was calculated using the following variables: surface mining operating cost (US$1.60/t), processing costs (US$5.00/t), general and administrative costs (US$1.50/t), Mo price of (US$17/lb), Au price (US$1,050/oz), and metal recoveries (Mo 90%, Au 70%). Grade interpolation of Mo and Au were made using ordinary kriging. The resource was reported within a preliminary open pit shell. Work needed to bring it to current: In order to bring Cinco de Mayo historical mineral resources current for both the Upper Manto and Pozo Seco Deposits, Apollo would need to conduct a review the historical database, update the metal prices, recovery and NSR factors, and update the geological and resource models
