Eskay Mining controls several other gold and silver showings to the south and east of SIB, these include the TV and Jeff zones, Mitchel North, and a group of 14 prospects collectively grouped into the Corey property. Previous exploratory drilling at Corey suggests that the C-10, Cumberland, Red Lightning, and Tet prospects have the highest gold and/or silver grades; with several intercepts above 5 g/t gold. A surface sample collected from the Tet showing contained 37,366 g/t Ag, indicating a significant precious metal anomaly. The Mitchell North prospect has been proposed to have similar geology and hydrothermal alteration to the neighboring Brucejack, Kerr, Sulphurets, and Mitchell deposits.
The style of mineralization and alteration at these deposits is poorly understood, with genetic models as diverse as VMS, epithermal, porphyry, and ultramafic Ni-PGE type deposits having been proposed. Previous drilling at Corey went no deeper than 300 meters, and was confined to basaltic rocks. Preliminary analysis of existing bulk rock geochemistry has shown a distinct chlorite and carbonate alteration style compared to the SIB property. The 2020 exploration program proposes to relog and perform handheld XRF analysis on select historic drill core, perform focused surface mapping and sampling, and to drill a 1000 meter hole at C-10 to better characterize the mineralizing systems at Corey. This work will enable the development of a targeted exploration program for the 2021 season.
