Mar 27, 2013 (A Wilson) - The property is underlain by a sequence of mafic and felsic metavolcanic rocks, chloritic schists and mafic intrusive rocks. Conglomerates, siltstones and quartzites of the Coleman Formation overlie the metavolcanic rocks.

Aug 18, 2017 (A Wilson) - The best assay reportedly returned 1.8 oz/t Ag over 1 inch in a drill hole completed by Silver Tower Mines. Other typical assays ranged from 0.2 to 0.8 oz/t Ag over lengths ranging from 1 to 4 inches. Galena was observed within a chlorite schist in irregular streaks over a maximum width of 5 feet. Minor pyrite and carbonate also was observed. Traces of pink carbonate also carried galena and minor cobalt bloom. The mineralization appears to lie adjacent to the contact with the overlying metasedimentary rocks. In the south-central part of the property, galena is exposed in a prospect pit. The galena is in a chlorite schist in irregular streaks over a maximum width of 5 feet. Minor pyrite and carbonate are also present. The galena is in small grins and constitutes up to 10-15% of the rock. The galena is inconspicuous on the weathered surface. About 80 ft. west of the pit is a small fracture along which are traces of pink carbonate vein material containing galena and minor cobalt bloom. The assay results from the Silver Tower Mines core samples ranged from nil to 1.8 oz. per ton.
