TDG Gold Corp. Defines Newberry Exploration Target Area Adjacent to Greater Shasta - Seite 3

As noted above, Marsden and Moore (1990) mapped a north-northwest trending down to the east fault across the area, which they named the West Fault, that is coincident with the soil anomaly, outcropping alteration and mineralization. It appears to trend towards the trace of the Shasta Fault, but glacial and alluvial cover in the intervening area makes accurate mapping from surficial exposures difficult and it may be a separate structure and the sense of displacement appears opposite than the main Shasta Fault. In the area of the Newberry prospect, rocks that are poorly exposed west of the fault include a complex sequence of quartz-free biotite-hornblende-feldspar-phyric volcanic breccia and spherulitic lapilli tuffs. Rocks exposed east of the fault consist of an interpreted younger package of grey dacite known as the Saunders Creek Dacite that consists of dark grey Iapilli tuffs containing quartz, biotite, hornblende and feldspar crystals, moderately flattened feldspar-phyric lapilli and intrusive fragments that are contained both within the lapilli and the matrix. The matrix consists of flattened and welded glass shards. Both these units are texturally and compositionally similar to those that occur in the hanging wall and footwall to the Shasta Deposit, 2 km to the south-southeast, but are interpreted to be higher and younger in the volcanic stratigraphic section by Marsden and later operators.

Mapped alteration around the prospect consists of calcite and quartz cemented breccias, quartz flooding and salmon-pink potassium feldspar replacement of the rock matrix, crystals and lithic fragments. Extensive iron oxides are present producing a small gossanous area near the top of the hill and the iron oxides appear to be the results of weathering of iron-rich lithologies and weathered sulfides minerals and the quartz-potassium feldspar flooding patterns mimic the trace of the soil anomalies and iron oxide occurrences. Sulfides reported from hand specimens include pyrite, sphalerite, galena minor chalcopyrite and their oxidized equivalents.
