In May, 2021 Crestview conducted a core drill program in the area of the historic resource to begin to validate the historic record and begin testing deeper zones for mineralization.
SA-01 and SA-03 each intercepted significant zones of gold mineralization. SA-01 and SA-03 were drilled approximately 200 m apart, which may represent a wide area of oxide, heap-leachable gold mineralization starting at or near the surface.
SA-02 and SA-04 each intercepted three short intervals of anomalous gold mineralization at similar depths, suggesting these zones may be continuous.
The mineralized zones occur in highly fractured/faulted volcanic rocks of pyroxene andesite, welded vitric tuff, and volcanic mudflow breccia.
The mineralized zones contained abundant iron oxides (jarosite> hematite> geothite), moderate to abundant argillic alteration, minor silicification, minor propylitic alteration, and late calcite.
