Pastos Grandes is near ready to test for the Tectoniq proprietary HAMS (HyperAluminous Mineralised System), requiring only drone magnetics to aid drill campaign planning.
Located 30km southwest of San Antonio de los Cobres and ~125km NW of Salta city, this NE-SW trending valley is situated at the margin of the Agua Calientes caldera.
These highly prospective properties include exploitation licenses and exploration licenses.

Key geologic and geographic features:
Overlapping calderas of ~17 and ~10Ma
Fault control on caldera formation and subsequent juxtaposition
Two generations of epithermal mineralisation; La Poma Ag-Pb-Zn at ~17Ma driven by subvolcanic dome emplacement, and Incahule Sb-Au at ~10Ma driven by waning post-caldera heat flow.
Recent Shoshonitic magmatism
