Cerro Blanco is a near surface high grade gold deposit, in Jutiapa, Guatemala. An N.I. 43-101 technical report on the project was produced and filed in April 2022. The Mita Geothermal project 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 challenging the approval procedure that approved the surface mining method for Cerro Blanco. Bluestone has the view that the environmental permit amendment met and exceeded the terms of reference provided by the MARN, and it adhered to Guatemalan law. Aura intends, upon closing of the transaction, to evaluate the alternatives for a future potential development of Cerro Blanco.

Rodrigo Barbosa, CEO of Aura, added, “Cerro Blanco stands as a world-class deposit that has encountered both social and institutional hurdles. We are confident that, along the next few years, by integrating it with Aura’s 360 vision, we can refine our strategic approach to make Cerro Blanco another flagship project that exemplifies the utmost respect for social and environmental responsibilities while delivering value to all stakeholders.”

Peter Hemstead, President, CEO, and Board Chair of Bluestone Resources, stated, “After a fulsome Strategic Review Process, the acquisition by Aura provides the best outcome for Bluestone shareholders and to further advance the Cerro Blanco gold project and Mita geothermal project. The Transaction presents shareholders with a choice to maintain exposure to Cerro Blanco through a proven Latin America mine developer and producer with a strong balance sheet or elect cash. Aura is a well established Latin American producer with a track record of development and has the financial capacity to advance and unlock potential value from Cerro Blanco.”
