Apollo Gold & Silver Signs Definitive Acquisition Agreement to Create Significant US Pure Silver Exploration and Development Company

Highlights:

• A US based pure silver opportunity with three advanced assets in mining friendly regions of Southeast California and Arizona;
• Over 100 million (M) ounces of silver in one of three historic resources⁽¹⁾. Significant exploration upside;
• US critical mineral status due to barite content and growing importance of silver in clean energy applications; and
• Appointment of Tom Peregoodoff as President and CEO of the Company with further additions to the board of directors.

The combination of Apollo and Stronghold creates a team with deep technical and operational experience, a strong profile in capital markets and a broad and supportive shareholder base. The Stronghold silver assets represent some of the largest, undeveloped, advanced silver projects in the US. In addition, the assets are silver-barite systems with 10-12% barite, a mineral deemed critical to the US economy and sourced primarily through importation, with China the major supplier.

Commenting on today's announcement, Apollo Chairman, Andrew Bowering said, "the signing of this agreement is a major achievement and a transformational moment for Apollo shareholders. We look forward to establishing the Company's presence in the US and the silver sector as a major player as we focus our efforts on unlocking value at Waterloo, Langtry and The Arizona Silver District with new exploration activities. I am also delighted to welcome Tom Peregoodoff to our team. His experience, knowledge and relationships will be instrumental as we drive forward these high-profile projects."

"With the definitive agreement signed we look forward to completing this transaction with our new partners at Apollo," said James Hynes, Stronghold CEO. "We are very excited about the future for these projects as silver continues to build momentum in new, as well as traditional, applications. We are confident in the Apollo team's ability to drive future value as we expand on the strong fundamentals of the combined assets."

Table 1 Historic Mineral Resources

The historical mineral resources discussed in this press release were calculated prior to the implementation of the standards set forth in NI 43-101 and current CIM standards for mineral resource estimation (as defined by the CIM Definition Standard on Mineral Resources and Ore Reserves dated May 10, 2014). The reader is cautioned not to treat them, or any part of them, as current mineral resources or reserves. The estimates do not classify the resource as either a measured, indicated or inferred resource and, accordingly, readers should not assume it satisfies the requirements of any of such classifications. There is insufficient information available to properly assess the data quality, estimation parameters and standards by which the estimates were categorized. An independent Qualified Person ('QP'), has not done sufficient work to classify the estimate discussed as current mineral resources or reserves and therefore the estimate should be treated as historical in nature and not current mineral resources or mineral reserves. The historical resources have been included simply to demonstrate the mineral potential of the projects. A thorough review of all historical data performed by a QP, along with additional exploration work to confirm results, would be required in order to produce a current mineral resource estimate for all projects.

Terms of the Transaction:

Under the terms of the Agreement, Apollo will issue a total of 40 M common shares to Stronghold shareholders on a share exchange ratio of one Apollo common share for one Stronghold common share (the "Exchange Ratio").

The Transaction is expected to constitute a "fundamental acquisition" of Stronghold by the Company pursuant to TSX Venture Exchange (the "Exchange") Policy 5.3 and will require approval of the Exchange and be subject to requirements the Exchange may impose. In addition, it is a condition of closing that Apollo must complete a financing of a minimum of C$35,000,000 (the "Concurrent Financing") the details of which will be released in due course. There are a number of other closing conditions as are customary for transactions of this nature.

Finally, in the event the Transaction is not completed on or before June 30, 2021, the Agreement will terminate unless mutually agreed.

Cautionary Statement Regarding Historic Estimates

Any reference to historical estimates and resources should not be relied upon. These are not current and a Q.P. has not done sufficient work to classify these historical estimate and Apollo is not treating the historical estimate as a current resource estimate. This document uses the terms " resources", "measured resources", "indicated resources" and "inferred resources". United States investors are advised that, while measured resources, indicated resources and inferred resources are recognized and required by Canadian securities laws, the United States Securities and Exchange Commission (the " SEC") does not recognize them Under United States standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. United States investors are cautioned not to assume that all or any part of measured or indicated resources will ever be converted into reserves. Further, inferred resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. It cannot be assumed that all or any part of the inferred resources will ever be upgraded to a higher category. Therefore, United States investors are also cautioned not to assume that all or any part of the inferred resources exist, or that they can be mined legally or economically. Disclosure of "contained ounces" is permitted disclosure under Canadian regulations, however, the SEC normally only permits issuers to report "resources" as in place tonnage and grade without reference to unit measures. Accordingly, information concerning descriptions of mineralization and resources contained in this release may not be comparable to information made public by United States companies subject to the reporting and disclosure requirements of the SEC. National Instrument 43 101 Standards of Disclosure for Mineral Projects ("NI 43 101") is a rule developed by the Canadian Securities Administrators, which established standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Historical resource estimates contained in this document have not been prepared in accordance with NI 43 101 and the Canadian Institute of Mining, Metallurgy and Petroleum Classification System.
