02/23/2021 (T Pettigrew) - The Goodman-Kodiak property is situated along a major tectonic break, known as the Empire Fault. The Empire Fault cuts through the property from the southwest, to the northeast comer within a belt of metavolcanics. These metavolcanics are bounded both north and south by metasedimentary units. Areas of interest are the areas of alteration, sulphide mineralization and quartz veining which have intruded the metavolcanic unit. Intruding the shear zone are two boudinaged quartz veins, one striking generally east-west and ranging in width from 5 to 25 cm. The second vein is further north and roughly 10 meters apart at the midpoint of the stripped area. This vein strikes roughly 80° Az and obtains a maximum width of 50 cm. These veins converge near the west end of stripping with the southern vein being lost in thick overburden just beyond the midpoint of stripping. Both the sheared, siliceous, fine grained pillowed metavolcanic host rock and the whitish to grey recrystallized quartz exhibit chlorite-sericite alteration. Mineralization consisting of fine to semi-coarse pyrite and pyrrhotite usually found in disseminations and narrow seams along fracture planes are found within the metavocanics. In addition to the pyrite-pyrrhotite, the quartz matter exhibits chalcopyrite and arsenopyrite mineralization found in varying concentrations upwards of 10%. Samples collected during Kodiak’s 2008 program returned up to 12.4 g/t Au from greyish quartz with 10% arsenopyrite and pyrite (Assessment report 20000003305). The best assay returned from the 1995 program was 0.33 oz/t Au (11.32 g/t Au) from a graphitic blue-grey quartz vein within sheared metavolcanic with 2-3% pyrite and lesser arsenopyrite (Assessment report 42E12SW0052). Goodman’s Site "B" revealed a series of continuous and discontinuous blue-grey waxy sugary recrystallized quartz veins, veinlets and lenses. The veins pinch and swell into lenses a meter wide at various locations in the exposed area. The quartz material is hosted in slightly sheared, siliceous, fine-grained metavolcanics with moderate chlorite-sericite alteration. Within the quartz matters arsenopyrite mineralization is more abundant in the blue-grey quartz (up to 5%) and minor to rare in the recrystallized white quartz. Mineralization is found in massive granular patches and along fractures with the host metavolcanics. In one location coarse chalcopyrite is found along with massive arsenopyrite in a blue-grey quartz lens. Mineralization of the host metavolcanics consist of fine disseminated pyrite and abundant fine, narrow seams of pyrrhotite, with sulphide content reaching roughly 3%. In one location at the extreme east end of the exposure abundant arsenopyrite crystals are found in the wallrock adjacent to a 2 meter wide quartz lens. The strike of the metasediments is 65 to 70 degrees with the veining system generally following the same strike, but in some cases striking more easterly. Samples collected in 1994 returned up to 0.047 oz/t Au (1.61 g/t Au) from a blue-grey quartz with patches of coarse chalcopyrite and 0.063 oz/t Au (2.16 g/t Au) from a blue-grey quartz and sheared metavolcanic with disseminated pyrrhotite and arsenopyrite (Assessment report 42E12SW0025). DDH GMO-08-01 returned 0.55 g/t Au over0.4 m from quartz-carbonate veining in lightly altered and moderately sheared basalt (Assessment report 20000004534).
