Scout, Idaho

Scout is located 25 km NE of Bonners Ferry, ID. It is road accessible by paved highway from Bonners Ferry, and then from gravel and dirt roads into the project area. It was staked in 2020 and is 100% owned by EMX. The project is a 3 km-long Gold-Silver vin system within the Eastern Cordilleran Orogenic Gold belt with minimal outcrop. Quartz-pyrite-arsenopyrite (±galena-sphalerite) veins hosted in Proterozoic Belt-Purcell Basin quartzite and potentially Proterozoic mafic sills at depth. EMX rock chip samples up to 40.0 g/t Au (n=19, avg. 9.3 g/t Au, max=40.0 g/t Au) from two historic underground mines separated by 1.5 km of strike length. Veins are 0.5-2m thick and dip 55-85° SW, historic underground channel sample at the Buckhorn Mine of 0.9m @ 18.0 g/t Au + 216 g/t Ag.

The host rocks on the property are Proterozoic Belt-Purcell rift basin quartzite (Prichard Formation) and potentially Proterozoic Moyie mafic sill complex (ideal Fe source for sulfidation reactions and Au deposition).

Structures are regionally and locally folded units, veins hosted within regional shear zone with normal-oblique (right lateral?) kinematics. Alteration present is Quartz-pyrite-arsenopyrite (±galena-sphalerite) veins with localized silicification, sulfidation, and sericitization of wallrock. There is an Au:Ag ratio of 0.6:1 (n=19 rock samples), and strong Au-Ag-As-Bi geochemical association.

The targets on property are the high-grade, underground mineable quartz vein-hosted gold. There is opportunity to discover new veins and extensions of known veins covered by shallow soil and vegetation. Drill-ready targets near historic high-grade underground mines; generate additional targets with systematic field mapping, stream and soil geochemistry (strong Au-Ag-As geochemical association), and geophysics.
