Mineralization Comments

Jun 30, 2020 (Therese Pettigrew) - DDH T-10 returned 0.025 oz/t Au over 1 foot (0.86 g/t Au over 0.3 m) and 0.05 oz/t Au over 3 feet (1.71 g/t Au over 0.91 m) from siliceous basalt with 15% pyrite and 10-15% quartz (Assessment report 52F16NW0024). The Jacobus Creek Showing area is characterized by large volumes of felsic intrusives of estimated granodioritic composition; both equant and porphyritic quartz or quartz-feldspar porphyry sills were observed. In many locations, the felsic intrusives are altered and contain moderate pyrite. Alteration mineralogy is variable but most commonly quartz/sericite/ankerite, with occasional albite and chlorite alteration. Pyrite is commonly euhedral and disseminated in altered rocks, with pyrite contents of individual outcrops ranging from 1% to 5%. Quartz-ankerite veining was also observed in several outcrops. Eight grab samples were collected during the 2011 program, and the highest assay was 0.025 g/t gold from I589749 (Assessment report 20000008131).
