Aura Announces Receipt of the Construction License and Commencement of Early Works at the Era Dorada Project

ROAD TOWN, British Virgin Islands, Jan. 06, 2026 (GLOBE NEWSWIRE) -- Aura Minerals Inc. (NASDAQ: AUGO, B3: AURA33) (“Aura” or the “Company”) is pleased to announce that it has received the construction license and commenced early works for the development of the Era Dorada Project (“Era Dorada” or the “Project”), marking a significant milestone in the Project’s advancement. A copy of the Era Dorada Feasibility Study has been filed on EDGAR at  and CVM at and is also available on Aura’s website.

The early works activities include environmental programs, controlled vegetal suppression, main road detour, internal road access opening, mine dewatering and preparation of platforms to accommodate equipment and temporary facilities.

In January 2025, Aura completed the acquisition of Bluestone Resources Inc. (“Bluestone”), the 100% owner of the Era Dorada project (formerly known as Cerro Blanco), located in Jutiapa, Guatemala. The project was acquired with all preliminary licenses for the underground mine and today received the final construction license.

Rodrigo Barbosa, Aura’s President and CEO commented, “After extensive dialogue with local authorities and community representatives—during which we shared detailed information about Aura and our Era Dorada project, including our recent formal decision to proceed exclusively with underground operations—we obtained the construction license, which was a requirement to advance and commence early works on the project. At the Era Dorada project, we have spent so far more than 853 hours establishing ongoing dialogue roundtables with local communities—direct, continuous forums that exemplify our commitment to transparency and inclusion. At Aura, we are deeply committed to responsible mining, upholding human rights, and ensuring that the development of Era Dorada delivers distributed, positive impacts for both the environment and surrounding communities.”

Era Dorada Project

The Project is located in southeast Guatemala, in the Department of Jutiapa, approximately 160 km by road from the capital, Guatemala City and approximately 9 km west of the border with El Salvador. The nearest town to the Project is Asunción Mita, a community of about 18,500 people situated approximately 7 km west of the Project. The exploitation license covers 15.25 km² and lies entirely in the municipality of Asunción Mita.

The Era Dorada Project site is accessible year-round via the Pan-American Highway (CA1) through Asunción Mita, with flat to rolling hill topography. The climate is tropical dry forest, with elevations of 450–560 masl, a wet season from May to October, 1,350 mm annual rainfall, temperatures ranging from 10°C to 41°C, 2,530 mm annual pan evaporation, and 62% average humidity. The site is near communities, including Asunción Mita (18,500 population), and the La Baranca power substation (20 MW capacity) a few kilometers south. No prior mining exists in the area, but the closure of Goldcorp’s Marlin Mine in 2017 provides access to trained Guatemalan labor. The project plans to hire locally, with training costs included in the budget.
