Sandstorm Gold Royalties Supports Royal Gold's Acquisition of Kansanshi Gold Stream

VANCOUVER, BC, Aug. 5, 2025 /PRNewswire/ - Sandstorm Gold Ltd. ("Sandstorm Gold Royalties", "Sandstorm" or the "Company") (NYSE:SAND) (TSX:SSL) today acknowledges and supports Royal Gold Inc.'s ("Royal Gold") acquisition of a gold stream on the Kansanshi copper-gold mine for US$1 billion. Royal Gold announced earlier today that the company has entered into a precious metals purchase agreement for gold deliveries referenced to copper production from the Kansanshi copper-gold mine in the North Western Province of Zambia, operated and 80% owned by a subsidiary of First Quantum Minerals Ltd. Royal Gold will fund the gold stream with available cash and the company's revolving credit facility without issuing new shares. For full details, refer to Royal Gold's press release dated August 5, 2025.

"Sandstorm is pleased to support Royal Gold's acquisition of the Kansanshi gold stream," commented Nolan Watson, President and CEO of Sandstorm. "Our acquisition agreement with Royal Gold specifically contemplated the potential for a large stream acquisition before closing the Royal Gold/Sandstorm transaction, and we are pleased with today's announcement. Being part of a larger and well-capitalized entity creates the opportunity for Sandstorm shareholders to benefit from exposure to larger acquisitions. The Kansanshi transaction is an excellent example of a cash-flowing stream on a large, long-life mine with current reserves supporting a 20-year mine life from a first-tier operator. The gold stream is expected to add approximately 35,000 to 40,000 ounces per year over the next 10 years, further enhancing the combined portfolio."

On July 6, 2025, Sandstorm entered into a definitive arrangement agreement with Royal Gold pursuant to which Royal Gold will acquire all of the issued and outstanding common shares of Sandstorm in an all-share transaction. For more information regarding the proposed acquisition, refer to the Company's press release dated July 7, 2025.

CAUTIONARY STATEMENTS TO U.S. SECURITYHOLDERS

The financial information included or incorporated by reference in this press release or the documents referenced herein has been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board, which differs from US generally accepted accounting principles ("US GAAP") in certain material respects, and thus are not directly comparable to financial statements prepared in accordance with US GAAP.

This press release and the documents incorporated by reference herein, as applicable, have been prepared in accordance with Canadian standards for the reporting of mineral resource and mineral reserve estimates, which differ from the previous and current standards of the United States securities laws. In particular, and without limiting the generality of the foregoing, the terms "mineral reserve", "proven mineral reserve", "probable mineral reserve", "inferred mineral resources,", "indicated mineral resources," "measured mineral resources" and "mineral resources" used or referenced herein and the documents incorporated by reference herein, as applicable, are Canadian mineral disclosure terms as defined in accordance with Canadian National Instrument 43-101 — Standards of Disclosure for Mineral Projects ("NI 43-101") and the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM") — CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the "CIM Definition Standards").

For United States reporting purposes, the United States Securities and Exchange Commission (the "SEC") has adopted amendments to its disclosure rules (the "SEC Modernization Rules") to modernize the mining property disclosure requirements for issuers whose securities are registered with the SEC under the Exchange Act, which became effective February 25, 2019. The SEC Modernization Rules more closely align the SEC's disclosure requirements and policies for mining properties with current industry and global regulatory practices and standards, including NI 43-101, and replace the historical property disclosure requirements for mining registrants that were included in SEC Industry Guide 7. Issuers were required to comply with the SEC Modernization Rules in their first fiscal year beginning on or after January 1, 2021. As a foreign private issuer that is eligible to file reports with the SEC pursuant to the multi-jurisdictional disclosure system, the Corporation is not required to provide disclosure on its mineral properties under the SEC Modernization Rules and will continue to provide disclosure under NI 43-101 and the CIM Definition Standards. Accordingly, mineral reserve and mineral resource information contained or incorporated by reference herein may not be comparable to similar information disclosed by United States companies subject to the United States federal securities laws and the rules and regulations thereunder.

As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes estimates of "measured mineral resources", "indicated mineral resources" and "inferred mineral resources." In addition, the SEC has amended its definitions of "proven mineral reserves" and "probable mineral reserves" to be "substantially similar" to the corresponding CIM Definition Standards that are required under NI 43-101. While the SEC will now recognize "measured mineral resources", "indicated mineral resources" and "inferred mineral resources", U.S. investors should not assume that all or any part of the mineralization in these categories will be converted into a higher category of mineral resources or into mineral reserves without further work and analysis. Mineralization described using these terms has a greater amount of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, U.S. investors are cautioned not to assume that all or any measured mineral resources, indicated mineral resources, or inferred mineral resources that the Company reports are or will be economically or legally mineable without further work and analysis. Further, "inferred mineral resources" have a greater amount of uncertainty and as to whether they can be mined legally or economically. Therefore, U.S. investors are also cautioned not to assume that all or any part of inferred mineral resources will be upgraded to a higher category without further work and analysis. Under Canadian securities laws, estimates of "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies, except in rare cases. While the above terms are "substantially similar" to CIM Definitions, there are differences in the definitions under the SEC Modernization Rules and the CIM Definition Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that the Company may report as "proven mineral reserves", "probable mineral reserves", "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" under NI 43-101 would be the same had the Company prepared the reserve or resource estimates under the standards adopted under the SEC Modernization Rules or under the prior standards of SEC Industry Guide 7.
