Sandfire Resources America Acquires Key Mine Property at the Black Butte Copper Project

WHITE SULPHUR SPRINGS, Aug. 11, 2021 - Sandfire Resources America Inc. ("Sandfire America" or the "Company") is pleased to advise that it has taken another important step in advancing its fully permitted Black Butte Copper Project in Central Montana with the acquisition of a key property covering the proposed surface infrastructure.

Tintina Montana Inc., a wholly owned subsidiary of Sandfire Resources America Inc., completed the purchase of the 534.9-acre Mine Property from Bar Z Ranch Inc. ("Bar Z") on July 22, 2021.

This property encompasses a majority of the area of surface disturbance and activity allowed in the Mine Operating Permit for the Johnny Lee Deposit, which was approved by the Montana Department of Environmental Quality ("MT DEQ") on August 17, 2020.

Facilities include the future underground mine entrance and portal pad, mill facility, contact water reservoir, cemented tailings facility, and other features. The purchase was conducted under the arrangement outlined in the Company's contract with the surface property owner, Bar Z. The land sale only encompasses surface rights and does not include the associated Mineral Rights, which will continue to be owned by their current owners.

The Black Butte Copper Project is located wholly on private land in Meagher County, Montana. The traditional use of the land is for grazing cattle and the project has been designed to return the land to ranchland at the end of the mine life.

Legal Update

On July 16, 2021, District Court Judge Bidegary heard oral arguments for summary judgement from plaintiffs and defendants regarding a legal complaint filed on June 4, 2020 by the plaintiffs claiming to represent the environmental community. The suit was filed jointly against the MT DEQ and Tintina Montana Inc.

Additional intervenors in the suit supporting the MT DEQ and Tintina Montana Inc, include Meagher County, Broadwater County, and the Montana Department of Justice. A decision on the case is pending and may take several months.

To date, the legal challenge has not resulted in any interference with development activities and construction continues. While the Company does not believe that the legal challenge has any merit, it does have the potential to delay the development timeline.

Commenting on the latest developments, Sandfire America's Senior Vice President Jerry Zieg said: "After years of developing strong community partnerships and often exceeding the standards set by one of the toughest regulatory processes in the world, the Company believes that the Black Butte Copper Project is cited as one of the most comprehensive mining plans Montana has ever seen - with state-of-the-art environmental safety features created expressly to protect the natural environment, including the Smith River Valley. The Company believes that the Black Butte Copper Project is a project Montana can be proud of and is very defensible in court. We look forward to moving forward, creating jobs, and getting back to investing in Montana."

The Company has secured sufficient water rights to operate the Black Butte Copper Project, however these water rights required a modification to allow them to be used for mitigation as well as agriculture. On March 13, 2020, the Montana Department of Natural Resources issued a positive preliminary determination to grant the modification to the water rights.

A Hearings Examiner has been assigned to consider objections and ultimately issue a final determination on the modification to the water rights. The Company continues working on a resolution of the objections directly with the objectors to address their concerns prior to the final determination.

Financing

The Company has identified a requirement for a further US$12 million in funding in 2021 to allow it to progress its value-adding and risk mitigation strategy for the Black Butte Copper Project through to mid-2022. The Non-Executive Independent Directors and Management are reviewing a number of financing options and expect to make an announcement before the end of August.

Sandfire America's CEO Rob Scargill said: "Purchasing the land where our mine will be located is a significant milestone in the development of Black Butte. We have a strong, productive relationship with the local landholders and owning the land provides greater clarity between mining and ranching activities and allows both industries to exist side-by-side. The recent legal proceedings are a frustration to all involved in the Black Butte Copper Project, but we are making strong headway as we continue to build momentum in the project."
