AURA COMPLETES THE ACQUISITION OF BLUESTONE

Aura Minerals Inc. has completed the previously announced acquisition of Bluestone Resources Inc. by way of a plan of arrangement under Part 5 of Division 9 of the Business Corporations Act (British Columbia).

Aura paid approximately $26,255,313 in cash, 28.7 cents for each Bluestone share held, and issued 1,007,186 Aura shares, 0.0183 common share of Aura for each Bluestone share held. Bluestone shareholders also received contingent consideration in the form of contingent value rights (CVRs) providing the holder thereof with the potential to receive a cash payment of up to an aggregate amount of 21.2 cents for each Bluestone share, payable in three equal annual instalments, contingent upon the Cerro Blanco gold project achieving commercial production. The shares of Bluestone are expected to be delisted from the TSX Venture Exchange on or around market close on Jan. 14, 2025. Aura will apply for Bluestone to cease to be a reporting issuer in each relevant jurisdiction under applicable Canadian securities laws. The listing of the Aura shares issued as consideration to certain former holders of Bluestone shares is subject to final approval by the Toronto Stock Exchange.

Rodrigo Barbosa, chief executive officer of Aura, stated: "Cerro Blanco is a world-class deposit with over three million ounces in measured and indicated (M&I) resources. Over the next few months, we will be reviewing the feasibility study and exploring alternatives to optimize the size, risk and return of the project while rolling out our Aura 360 concept with the highest environmental and social standards, preparing it to start construction. Moreover, the geothermal energy project, with a capacity to reach 50 megawatts, gives Cerro Blanco a unique angle to use renewable energy and potentially sell the surplus to Guatemala. This acquisition exemplifies our ability to execute a growth strategy. Finally, we welcome one of the most reputable mining investors, the Lundin family, as our shareholders."

Bluestone is the owner of the Cerro Blanco project, which is a near-surface gold deposit located in Jutiapa, Guatemala. A National Instrument 43-101 technical report and feasibility study on the project were prepared by G Mining Services and filed publicly in April, 2022, by Bluestone. The report contains the following mineral resource estimates: 63.5 million tonnes at an average grade of 1.5 grams per tonne of gold and 6.6 g/t of silver for 3.09 million ounces of gold and 13.4 million ounces of silver contained in the measured and indicated mineral resources, along with 1.67 million tonnes at an average grade of 0.6 g/t Au and 2.1 g/t of silver for 31,000 ounces of gold and 112,000 ounces of silver contained in the inferred mineral resources. Bluestone also owns the Mita geothermal project, which is an advanced-stage renewable-energy project licensed to produce up to 50 megawatts of power. As previously disclosed by Bluestone, on June 17, 2024, Bluestone received a notice from the Guatemalan Ministry of Environment (MARN) challenging the approval procedure that approved the surface mining method for Cerro Blanco. In its public disclosure, Bluestone has clarified its belief that the environmental permit amendment met and exceeded the terms of reference provided by the MARN, and that it has adhered to Guatemalan law in this respect. Aura intends to evaluate the alternatives for future potential development of Cerro Blanco.

The company is disclosing contained ounces based on mineral resource estimates contained in the report which are based on an open-pit scenario. All mineral resources in the report were estimated in accordance with Canadian Institute of Mining and Metallurgy and Petroleum (CIM) definitions, as required under NI 43-101, with an effective date of Dec. 31, 2020. Mineral resources reported in the report demonstrate reasonable prospect of eventual economic extraction, as required under NI 43-101, based on an open-pit scenario. Mineral resources are not mineral reserves and do not have demonstrated economic viability.
