Active Projects Across Chile, Peru & Colombia
Los Azules-Q'Inti
The Los Azules-Q'Inti project is located in the Copiapó area of Chile's Atacama region, one of the world's most prolific mining districts. The project encompasses claims that ASG is actively exploring and advancing toward development.
Drill core sampling has confirmed the presence of mineralization consistent with the geological models for the area. Exploration activities are ongoing.
Princesa Lara
Princesa Lara is a development-stage mining project located in the Altos de Lipangue area, less than 40 kilometers from Santiago, Chile. ASG is evaluating the property for its production potential as part of the company's broader strategy to advance mining assets across the region.
EGM Colombia — Mina San Ramón
EGM Colombia S.A.S. operates the San Ramón gold mine in the municipality of Santa Rosa de Osos, Antioquia — 72 kilometers from Medellín, in one of Colombia's most established gold-producing districts. ASG holds a 45% interest in EGM Colombia S.A.S. (acquired March 2026; see the News page for the official release).
The operation holds five mining titles covering approximately 2,824 hectares, with concessions extending out to 2044 for gold and polymetallic minerals (copper, molybdenum, silver, platinum, zinc).
Reactivation
EGM took over a mine that had been fully vandalized and stripped of operational infrastructure. Starting from zero, the team dewatered the flooded tunnel network, restored the camps, rebuilt the main substation receiving power from EPM, constructed a new 200-tonne-per-day processing plant, and restarted production — all within 2025.
Current Operations
21 active production fronts plus four development headings feed a plant processing ~230 tonnes per day (projected 260). The mine spans 210 vertical metres across three levels, connected by more than 4,500 m of main ramp and 1,800 m of attack ramps. Annual gold production is in the 10,000 to 18,000 oz range.
Geology
Mineralization at Santa Rosa is hosted in a homogeneous diorite and controlled by an E–W shear zone dipping 65–80° north, extending 2 km along strike, 700 m down-dip, and 10–40 m in thickness. High-grade zones form in anastomosing quartz–sulfide veins with average true widths of 0.6–0.7 m — up to 6 m where structures converge. Mineralogy is quartz + pyrite + sphalerite (± galena, chalcopyrite) with an Au:Ag ratio of approximately 1:1.6. Sulfide content correlates directly with gold grade.
Environmental & Community
EGM operates under an active environmental license (originally granted in 2015) and has assumed 100% of the site's socio-environmental obligations, reporting compliance semi-annually. The program covers surface and groundwater balance, air and noise monitoring, waste management (including tailings, waste rock, hazardous materials, and explosives), soil protection, and restoration of degraded areas.
The mine is a meaningful local employer: 45% of staff come from Santa Rosa de Osos, and the company supports municipal institutions through training, communications, and local project funding.
