White Sulphur Springs, Montana– February 26, 2024 – Sandfire Resources America Inc. (“Sandfire America” or the “Company”) announces the positive ruling by the Montana Supreme Court which reversed a 2021 district court decision and instructed the District Judge to have the Montana Department of Environmental Quality (MT DEQ) to completely reinstate Tintina Montana Inc.’s Mine Operating Permit, of the Black Butte Copper Project.

The Montana Supreme Court granted the Company’s request for summary judgement allowing Black Butte Copper to move forward with construction of its highly engineered, underground copper mine. The Company won on all counts in the Montana Supreme Court decision with a 5-2 decision upholding the 2020 decision of the MT DEQ to allow copper mining at the Black Butte Copper Project, overturning a District Court ruling that had invalidated the mining permit.

The original suit was filed jointly against the Montana Department of Environmental Quality and Tintina Montana Inc. (“Tintina,” Sandfire America’s wholly owned subsidiary) on June 4^th, 2020, and the Montana Supreme Court heard oral arguments on the case on June 21, 2023. Additional intervenors in the suit supporting the MT DEQ and Tintina, include Meagher County, Broadwater County, and the Montana Department of Justice.

Lincoln Greenidge, CEO of Sandfire America shared, “Today’s victory in the Montana Supreme Court is a validation of the thoughtful and deliberate efforts of the Sandfire America team to design a world-class, environmentally safe mining project from the beginning. The fact is, ours is the most reviewed and examined proposed project in the history of Montana mining. The Court record stands at over 90,000 pages of testimony, information, and analysis. We thank the justices for their ruling, and their ability to recognize the amount of effort and extensive work that has gone into this project. Now, we look forward to progressing the project in a safe, responsible, and sustainable manner.”

Senior VP, Jerry Zieg concluded stating, “Tintina’s permit has been diligently considered by the professional and hardworking staff at the MT DEQ. It is a fantastic, well-designed project with a plan centered around safety which is why we were successful today. Over a decade ago, we set out to design a state of the art, environmentally protective underground mining project, and this decision is proof we’ve been successful.”

Black Butte Copper now has all permits to proceed with the project. Stipulated agreements regarding water rights granted through the Montana Department of Natural Resources and

Conservation (MT DNRC) for the project have been finalized with all water rights being issued and available. There is a challenge to the Montana Constitution’s definition of the “beneficial use of water” using Black Butte Copper’s water use permit to challenge this definition. This case does not currently affect the Company’s water rights package. The challenge, naming both the MT DNRC and Tintina Montana Inc., was appealed by objectors after their loss at District Court and will be heard by Montana Supreme Court on Friday, March 29, 2024.

Sandfire Resources America Announces 
 Successful Completion of Water Rights Permitting

White Sulphur Springs, Montana– November 1, 2022 – Sandfire Resources America Inc. ("Sandfire America" or the "Company") is proud to announce the necessary permits to appropriate water for the Black Butte Copper Project have been issued by the State of Montana Department of Natural Resources and Conservation (DNRC).

The permits issued by the DNRC authorize the Company to divert groundwater for use in the mining of the Johnny Lee copper deposit and to store high-water flows for stream flow maintenance. The DNRC also approved the Company’s change applications to use six existing water rights to mitigate surface water flow reductions resulting from the groundwater diversion. Water right permits and change applications are issued by the DNRC in accordance with the Montana Water Use Act (Title 85, chapter 2, MCA).

The Company, as the applicant, was required to prove the following criteria for issuance of the new water right permits:

• There is water physically available at the proposed point of diversion in the amount that the applicant seeks to appropriate;
• Water can reasonably be considered legally available during the period in which the applicant seeks to appropriate, in the amount requested;
• The water rights of a prior appropriator will not be adversely affected by the proposed new use;
• The proposed means of diversion, construction, and operation of the appropriation works are adequate;
• The proposed use of water is a beneficial use; and
• The applicant has a possessory interest or the written consent of the person with the possessory interest in the property where the water is to be put to beneficial use.

While the Company received objections to the water use permits and the mitigation changes, the Company was able to resolve all but one of the objections through negotiated settlements, which may not be challenged as agreed upon by the parties. The one remaining objection to the groundwater permit, which is pending before the Meagher County district court, relates to the DNRC’s interpretation of whether mine dewatering constitutes “waste” under the Montana Water Use Act.

Senior Vice President Jerry Zieg shared. “We are extremely pleased with this positive progress. We have now obtained the water permits needed to begin Phase II Construction of the mining operations at the Johnny Lee Deposit. We are optimistic that the remaining objection to the groundwater permit will be resolved in our favor.”

One other regulatory hurdle to Phase II Construction will be resolving the narrow issues going in front of the Montana Supreme Court regarding the mine operating permit, with opening briefs due November 1, 2022. Regulatory finalization will be followed by the requirement of the Sandfire Resources America Inc’s Board approval and securing financing.

White Sulphur Springs, Montana– August 16, 2022 – Sandfire Resources America Inc. (“Sandfire America” or the “Company”) is pleased to report diamond drill results of the successful 2021-2022 Lowry Resource Definition core drilling program on its Black Butte Copper Project. Between September 2021 and March 2022, the company completed sixteen new core holes for 8,936 meters of core.

Drilling Highlights

Highlights of the Lowry Zone Resource Definition program include the following drill intersections:

• SC21-268 intercepted 36.3 meters of 2.86% copper and 16.5 g/t silver in the Lowry Middle Copper Zone (LMCZ)

• SC21-265 intercepted 30.58 meters of 2.7% copper and 10 g/t silver in the LMCZ

• SC22-277 intercepted 13.51 meters of 3.93% copper and 17.4 g/t silver in the Lowry Lower Copper Zone (LLCZ)

• SC22-274B intercepted of 8.36 meters of 4.30% copper and 9.2 grams silver in the LLCZ

Assay results are reported by mineralized zone in Table 1.

Drilling in the Lowry Middle Copper Zone largely confirmed grades and thicknesses of previous drilling, defined resource edges more clearly, and infilled gaps within the previous drill pattern. Drilling in the Lowry Lower Copper Zone delineated an area with somewhat higher copper grades which remains open for further expansion (see results for SC22-274B and SC22-277 below). Several holes intercepted copper mineralization above the LMCZ in the Lowry Upper Copper Zone  (see results for SC21-264, SC21-266 and SC21-268).

The results of this drilling will support a Lowry Pre-Feasibility Study planned for completion in 2023. Additional work for the prefeasibility study will include hydrologic, metallurgical, mining, and geotechnical studies.

Sandfire Resources America Inc. Senior VP Jerry Zieg commented: “The success of this drill program increases the scale and quality of the Lowry copper deposit and adds significant value to the Black Butte Copper Project. It represents a future opportunity for additional copper production with minimal impact to our  disturbance footprint. Protecting the environment while providing benefits to all our stake holders remains central to our strategy.”

Lowry Copper Deposit

The Lowry copper deposit is located approximately 2,500 meters east of the Johnny Lee deposit and has an Inferred Resource of 8.3 million tonnes of 2.4% copper (“Feasibility Study (Johnny Lee Deposit) and Mineral Resource Estimate Update (Lowry Deposit) – Technical Report NI 43-101” dated October 19, 2020, and the news release “Sandfire Resources America Achieves Major Milestones with Completion of Black Butte Copper Project Feasibility Study and Updated Mineral Resource for Lowry Deposit” October 27, 2020). Mine development of the Lowry copper deposit would require a thorough environmental review through the Montana Department of Environmental Quality (“MT DEQ”) permitting process, and completion of appropriate engineering and economic studies.

Johnny Lee Copper Deposit

The Johnny Lee deposit has a Measured and Indicated Mineral Resource of 10.9 million tonnes (Mt) at an average copper grade of 2.9% for 311 thousand tonnes (kt) of contained copper (Cu) at a 1.0% Cu cut-off grade, and an Inferred Mineral Resource of 2.7 Mt at an average copper grade of 3.0% for 80 kt of contained Cu at a 1.0% Cu cut-off grade (“Feasibility Study (Johnny Lee Deposit) and Mineral Resource Estimate Update (Lowry Deposit) – Technical Report NI 43-101” dated October 19, 2020, and the news release “Sandfire Resources America Achieves Major Milestones with Completion of Black Butte Copper Project Feasibility Study and Updated Mineral Resource for Lowry Deposit” October 27, 2020).  The Company has received a Mine Operating Permit from the Montana Department of Environmental Quality for mine development of this deposit and has completed a majority of Phase I construction on associated surface facilities.
