VANCOUVER, Sept. 12, 2024 /PRNewswire/ - Sandstorm Gold Ltd. ("Sandstorm Gold Royalties", "Sandstorm" or the "Company") (NYSE: SAND) (TSX: SSL) is pleased to provide various drilling and exploration updates from its diversified portfolio of streaming and royalty assets.

Lundin Gold Provides Bonza Sur Gold Discovery Updates; Expands Near-Mine Drill Program

Lundin Gold Inc. ("Lundin Gold") announced additional results from its 2024 near-mine drilling program, with recent intercepts continuing to delineate the new Bonza Sur gold deposit at the Fruta del Norte mine ("FDN"). The Bonza Sur gold deposit, discovered in 2023, is located 1 kilometre south of FDN. The deposit features a large mineralized envelope extending over 1.8 kilometres along strike, 100 metres wide, and at least 500 metres deep. More than 50 drill holes have been completed, revealing a higher-grade core with hydrothermal alteration and quartz veins. Lundin Gold's 2024 near-mine drilling program has been expanded by 10,000 metres to a total of 56,000 metres to further assess the deposit's full potential. As of August, the program had completed approximately 26,056 metres of drilling, the vast majority of which has been at Bonza Sur. The expanded program will increase costs by US$2 million, which combined with the regional program, results in an estimated program cost of US$44 million.

Lundin Gold is focused on expanding Bonza Sur's potential with a metallurgical study planned for 2024 and a maiden Mineral Resource Estimate is expected by mid-2025. As part of its recent Investor Day, the company highlighted the opportunity for Bonza Sur to be its second producing deposit within the La Zarza mining concession. A Preliminary Economic Assessment on Bonza Sur is expected prior to the end of 2025, which will outline the potential to develop a new 10,000–15,000 tonnes per day open pit mine at Bonza Sur.

Bonza Sur exploration highlights include (not true widths):

• BLP-2024-107: 2.01 grams per tonne ("g/t") gold over 113.3 metres from 6.5 metres, including:

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.
