Sandstorm Gold Royalties Portfolio Drilling and Exploration Highlights

VANCOUVER, BC, June 11, 2025 /PRNewswire/ - Sandstorm Gold Ltd. ("Sandstorm Gold Royalties", "Sandstorm" or the "Company") (NYSE: SAND) (TSX: SSL) is pleased to provide various developments and exploration highlights within its diversified stream and royalty portfolio (dollar figures in USD unless otherwise indicated).

First Majestic Confirms New Discovery at Santa Elena

First Majestic Silver Corp. ("First Majestic") has identified a significant gold-silver discovery on its Santa Elena property in Sonora, Mexico. The newly identified Santo Niño vein, located approximately 900 metres south of the Santa Elena processing plant, represents a significant addition to the district. The low-sulphidation, epithermal quartz-adularia vein has been traced over one kilometre along strike and 400 metres down-dip, with drilling to date confirming a mineralized core of approximately 600 metres by 220 metres. The discovery underscores the growing scale and potential of the Santa Elena district, which now hosts four major deposits, including Santa Elena and Santo Niño, which are both located within Sandstorm's stream area of interest.

Exploration results from 14 drill intercepts at Santo Niño have returned significant gold and silver grades. Notably, hole SE-25-15 intersected 1.91 metres grading 8.38 grams per tonne ("g/t") gold and 248 g/t silver, including 0.43 metres of 27.5 g/t gold and 641 g/t silver. The results highlight the high-grade nature of the mineralization and its continuity across the western portion of the vein system. The structure remains open in multiple directions, and follow-up drilling is planned throughout 2025 to further delineate its extent and potential.

The Santo Niño discovery complements the ongoing success at the Navidad deposit (not covered by Sandstorm's area of interest) where recent step-out drilling has expanded the mineralized footprint and returned some of the highest-grade intercepts ever recorded on the property. Together, Santo Niño and Navidad reinforce Santa Elena's status as a prolific, district-scale system with substantial upside. With nine rigs currently active, First Majestic is executing an aggressive exploration program aimed at unlocking further value and extending the mine life of this cornerstone asset.

For more information, refer to First Majestic's website at www.firstmajestic.com and refer to the press release dated May 28, 2025. Sandstorm holds a gold stream on the Santa Elena mine, which includes the Santo Niño discovery, whereby the Company has the right to purchase 20% of the gold produced at Santa Elena for ongoing cash payments of $487 per ounce of gold.

Fruta del Norte Expands 2025 Drilling Program to 108,000 Metres

Lundin Gold Ltd. ("Lundin Gold") has expanded its 2025 drilling program at the Fruta del Norte mine ("FDN") in Ecuador to at least 108,000 metres, following the program's success in the first quarter of 2025 and the growing pipeline of targets. The revised program represents the largest annual drill program ever completed on the land package that hosts the FDN deposit.

Additional drill results have been released from Lundin Gold's ongoing conversion and near-mine exploration program. High-grade intercepts from the conversion program at FDN South ("FDNS") have confirmed the deposit's continuity and identified additional mineralized zones. Studies are underway to integrate FDNS into FDN's 2026 long-term mine plan. Further high-grade results from FDN East continue to highlight the target's growth potential. At the recently discovered Trancaloma target, results confirm a copper-gold porphyry system at surface and highlight the potential for other porphyries near Trancaloma. At Bonza Sur, drilling confirms the mineral envelope and indicated the potential for further extension. Highlighted drill results include (not true widths):

Drill Results Reinforce District-Scale Potential of Odienné Project

Awalé Resources Ltd. ("Awalé") continues to report on its 2025 drilling campaign at the Odienné project in Côte d'Ivoire. Results from drilling across three key targets—BBM Zone, Charger, and Empire—have returned multiple high-grade gold and polymetallic intercepts, reinforcing the district-scale potential of the project. BBM Zone, Charger, and Empire are part of a broader pipeline of targets at Odienné, where Awalé is executing an 18,000-metre drill campaign. The project is being advanced as a potential mining camp with multiple feed sources for a central processing facility.

BBM Zone

Awalé has released the final results from a 22-hole, 6,380-metre drill program at the BBM Zone, confirming a broad gold-copper system extending over 1 kilometre of strike and to depths of 300 metres. Notably, hole OEDD-131 returned 45.0 metres of 1.4 g/t gold and 0.41% copper from 220 metres, including 4.0 metres of 2.6 g/t gold and 0.55% copper. The BBM Zone remains open down plunge, with a 300-metre-wide higher-grade core and multiple satellite targets identified within two to three kilometres, representing a key component of Awalé's broader exploration strategy at the Odienné project.

Charger Target

At the Charger target, Awalé reported high-grade gold and polymetallic intercepts from nine diamond drill holes, including:

• OEDD-120: 26.0 metres of 12.0 g/t gold from 146 metres;
• OEDD-118: 95.0 metres of 1.8 g/t gold from 170 metres; and
• OEDD-121: 4.0 metres of 18.5 g/t gold and 3.03% copper from 67 metres.

Additionally, a new parallel mineralized breccia zone was discovered 50 metres west of the main corridor, with 26.0 metres of 2.0 g/t gold in hole OEDD-137. These results support the presence of multiple mineralized structures and highlight the scalability of the Charger system.

Empire Target

Awalé has resumed drilling at the Empire target, which is the company's first high-grade gold discovery at Odienné, discovered in 2019. Empire sits within a 20 kilometre west-northwest trending structure corridor, and 2.5 kilometres south of the Charger discovery. Six diamond drill holes at Empire were completed, totalling 1,168 metres, and intersected significant mineralization, including:

• OEDD-127: 15.0 metres of 5.2 g/t gold from 215 metres, including 10.0 metres of 7.5 g/t gold;
• OEDD-114: 16.0 metres of 3.0 g/t gold from 44 metres; and
• OEDD-124: 19.0 metres of 2.3 g/t gold from 76 metres.

Exploration at Empire to date has covered only 5 kilometres of the Empire trend, with significant potential for further expansion. The results confirm the continuity of mineralization at depth and along strike, with Empire remaining open in multiple directions.

For more information, including complete drill results, visit Awalé's website at www.awaleresources.ca and refer to the press releases dated April 8, 17, and May 12, 2025. Sandstorm holds a 2.0% NSR royalty on the Odienné project.

Omai Gold Mines Drills 28.04 g/t Gold over 9.3 Metres at Wenot

Omai Gold Mines Corp. ("Omai") has released assay results from the 2025 drill program at the Omai gold mine in Guyana ("OGM"). A total of 15,639 metres of drilling has been completed in 2025, surpassing the planned 15,000 metres program as results continue to extend the known limits of the gold mineralization at Wenot. Additionally, several holes have been drilled in West Wenot—an area which lies outside of any previous mining and includes a significant part of the Wenot Mineral Resource Estimate ("MRE"). Omai believes West Wenot could be suitable for a starter pit in a production scenario. Highlighted drill results include:

Wenot Deposit

• 25ODD-103 & 103W: 3.56 g/t gold over 21.8 metres from 524.2 metres;
• 25ODD-103W: 3.93 g/t gold over 7.0 metres from 499.0 metres and 5.66 g/t gold over 4.3 metres from 560.0 metres; and
• 25ODD-102: 28.04 g/t gold over 9.3 metres from 361.2 metres, including 252.36 g/t gold over 1.0 metres.

West Wenot

• 25ODD-116: 2.63 g/t gold over 27.5 metres from 471.5 metres;
• 25ODD-111: 4.87 g/t gold over 9.5 metres from 317.0 metres, including 10.92 g/t gold over 4.0 metres; and
• 25ODD-109: 2.37 g/t gold over 15.0 metres from 79.0 metres.

Omai has also announced that drilling has begun on a deep hole that will initially drill across the Gilt Creek deposit, then continue a further 600–800 metres to explore the extension of the Wenot gold zones. The hole is expected to drill roughly 600 metres below the known Wenot deposit. 

Once South America's largest producing gold mine, the OGM produced over 3.7 million ounces ("Moz") of gold between 1993 and 2005. A Preliminary Economic Assessment ("PEA") released on the Wenot deposit in April 2024 envisioned an open pit operation producing 1.84 Moz of gold over a 13-year period. The 2024 PEA only incorporates 45% of the property's current MRE of 2.0 Moz of Indicated Mineral Resources and 2.3 Moz of Inferred Mineral Resources.

For more information and complete drill results, visit Omai's website at www.omaigoldmines.com and refer to the press releases dated May 12, 23, and 29, 2025. Sandstorm holds a 1.0% NSR royalty on the OGM.

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.
