Regional Gold Potential
Piedra Negra is located in Argentina, South America. The surrounding region has historically demonstrated a high potential for gold endowment and is somewhat distal to other gold properties. Physical setting (low elevation, moderate relief, dry climate) shapes access, seasonality, and operating costs. Geologically, the area is dominated by Basic volcanic rocks, under thin lithosphere with moderately thick sedimentary cover in a Meso- and Cenozoic Extended Crust tectonic province—factors that inform both deposit style and development complexity.
Drill Intercepts
Reported results (Gold) average very low grade, very short, and very shallow. The most recent intercepts are benchmarked against a global gold database.

|---|---|---|---|---|
| 2019-03-19 | 0.24 g/t Gold over 2.1 m from 21.6 m | Moderate Grade | Thick | Shallow |
| 2019-03-19 | 0.14 g/t Gold over 4.0 m from 37.0 m | Low Grade | Thick | Shallow |
| 2019-03-19 | 0.11 g/t Gold over 2.0 m from 20.0 m | Low Grade | Moderate Thickness | Shallow |
| 2019-03-19 | 0.66 g/t Gold over 2.0 m from 14.0 m | Moderate Grade | Moderate Thickness | Very Shallow |
| 2019-03-19 | 0.18 g/t Gold over 1.0 m from 26.0 m | Low Grade | Thin | Shallow |
| 2019-03-19 | 0.10 g/t Gold over 1.0 m from 16.0 m | Low Grade | Thin | Very Shallow |
| 2019-03-19 | 0.14 g/t Gold over 1.0 m from 19.0 m | Low Grade | Thin | Shallow |
