The Córdoba Opportunity: A Dormant Giant Reawakens
Historic Provenance
Córdoba's Sierra Chica and Sierra Grande regions hosted prolific gold and silver production from the 1500s through the early 20th century. Industrial-scale operations ceased in the 1930s due to collapsing commodity prices during the Great Depression and subsequent wartime strategic shifts.
Since then, over 300,000 metric tons of processed tailings with verified gold and silver values have remained untouched representing a zero-exploration risk, immediate-revenue asset.
Modern Viability
Official Argentine government data confirms highgrade shallow deposits at less than 200 meters depth, proven historic clusters with documented reserves, and tailings grades supporting greater than 1.5 g/t gold equivalent.
Today, gold prices exceeding $4,300/oz and silver above $50/oz have dramatically shifted the economics. New mechanical processing technologies and closed-loop water systems now enable full compliance with modern environmental standards.

Three-Phase Development Plan
Phase 1: Tailings Processing
Ramps up to process the full 300,000 mt of tailings over 12 months. This fullscale operation achieves annual production in excess of 5,000 tOz of gold, generating significant cash flow.
Phase 2: Exploration & Verification
Expand exploration and resource verification during months 13-24. Verify 220,000 tOz gold and 2,200,000 tOz silver detailed in historic reports.
Phase 3: Mine Reactivation
If historic resources are verified, reactivation can create 20,000 tOz per annum gold production with a 10-year life of mine.
Production Forecast & Revenue
The four-year tailings processing program targets 300,000 metric tons with conservative recovery assumptions of 1.6 g/t gold, 16 g/t silver, and 90% recovery rates. Using a 10:1 silver-to-gold ratio for gold equivalent calculations, the project generates substantial cash flow with minimal capital requirements.
ESG Leadership: Beyond Compliance
Sierras Minco is designed as a blueprint for the future of mining, embedding environmental and social responsibility into every operational decision. The project doesn't fight restrictions it thrives within them, proving that small-scale, sustainable mining can deliver superior returns while protecting communities and ecosystems.
Zero Chemical Use
Gravity and mechanical separation only, no cyanide, no mercury, no toxic reagents. This eliminates environmental liability and regulatory risk while protecting worker safety.
Closed-Loop Water
100% water recycling with zero discharge ensures no watershed impact. Rainwater harvesting supplements the system, removing dependence on stressed aquifers.
Renewable Power
Solar, wind, and biodiesel triad delivers carbonneutral operations from day one, with energy costs 60% below grid rates.
Blockchain Transparency
IoT-tracked ESG metrics recorded on immutable ledger provide real-time verification for investors and stakeholders. This is currently a research element being explored for future implementation.
Community Partnership
100+ local jobs, comprehensive training programs, and profitsharing arrangements ensure shared prosperity with Córdoba communities.
