Outlook
San Albino, Nicaragua’s newest high-grade gold mine, is a high-margin open pit operation. Based on a measured and indicated pit resource grade of 9.54 g/t Au, the project is one of the highest-grade surface mines in the world.
Our strategy is to consolidate a low-cost, cornerstone operation at San Albino– an area that only represents ~2% of our landholdings
Cash flow from San Albino is funding exploration on the district-scale Nicaraguan land package of ~188 sq. km

Geology and Mineralization
Mineralization at San Albino appears consistent with the orogenic gold deposit model: this deposit type is ultimately traced back to orogenesis (collisional plate tectonics). Orogenic deposits tend to occur on a district scale and are one of the largest deposit types in terms of gold endowment, tend to be high-grade and typically occur in clusters.
The gold-bearing veins at the project formed over a period of deformation, with alteration indicating a low degree of metamorphism. This metamorphism, together with thrust fault control suggests a high-level orogenic deposit at San Albino, analogous to Kinross’ (TSX: KGC; NYSE: K) Paracatu gold mine in Brazil.
Gold at San Albino is hosted in west-dipping quartz veins within shear (higher-strain) zones. The shear zones are typically stacked in a subparallel fashion, creating vein systems.
