Highest-grade zones of gold+copper mineralization (>1 g/t Au) exist in quartz+barite+sulfide veins localised near the intersections of lenses of quartz-altered facies and northwest trending faults in the central part of the system (Allibone 1998; Degeling et al. 1995). Sulfides in the veins are dominantly pyrite, with minor amounts of bornite ...

Unfortunately, no further work was undertaken on the property until 1960 when Tanar Gold Mines Ltd. of Vancouver stripped and test pitted the main vein to an extent of 4,100 feet on the surface. In 1961 Harvey H. Cohen, a mining engineer and Roger Verity of Tanar Gold Mines Ltd. inspected the property and wrote a favourable report but again ...

With high grade, native gold bearing quartz veins at surface, the project offers district scale potential. PowerOne was an early investor and acted as a finder in connection with a $4.32 million private placement in May 2016 and co-lead agent for a $16.36 million financing in July 2016.

The Mount Washington epithermal Au prospect is located near the city of Courtenay on Vancouver Island. Abiogeo-chemical study of the area, conducted by the Geological Survey of Canada in 1990, revealed strong geochemical signals of the commodity and pathfinder elements related to the underlying mineralization (Dunn, 1995, 2007). This

Three distinct styles of mineralization are known in the area, gold-cobalt skarns, gold-bearing quartz veins, and antimony-silver veins. The skarns are developed in carbonate layers within the metamorphic suite. Gold in the old Engineer Gold mine was in gold-bearing quartz-carbonate veins cutting Lower Jurassic Laberge strata.

Gold-bearing quartz veins have been found elsewhere in the granitic rocks. In addition, minor amounts of chalcopyrite, magnetite, molybdenite, and scheelite have been found but, generally speaking, developments to date have yielded little to encourage exploration of the granitic rocks, except along contacts with rocks that they intrude.

The gold occurs in thin, steep, vuggy quartz-sulphide veins cutting steeply across an epidote-chlorite, pyrite, sphalerite, chalcopyrite bearing vein with local development of bull quartz stringers, in a fault zone, cutting a gabbro sill, emplaced in the Paleozoic cherts. White vuggy veins carry sporadic gold values (up to 61 gpt Au)

The first core observation from hole Rim-20-06 identified the presence of visible gold. This hole is located approximately 100 metres south and along strike to the initial RIM vein showing. As at the RIM showing, the gold bearing quartz vein is located at a sandstone-siltstone contact.

deposits (Catface) and widespread, epithermal, gold bearing, quartz veins. These Tertiary stocks and limited, preserved volcanics are 40 to 55 million years old and represent continental arc magmatism above a paleo-subduction zone located west of the current coast of Vancouver Island.

The Bedwell River is situated near the western coast of Vancouver Island about 70 miles south of Zeballos. Placer gold was discovered in the river in the 1860s by Chinese miners who mined the river until 1880s. In 1898 veins bearing copper and gold quartz was discovered between the Big Interior Mountain and the river's mouth.

Placer deposits of gold are formed by the concentration of the gold from the debris of gold veins and other deposits of gold in rock. As the loose material is washed down hillsides into gullies and valleys, the gold, being six or seven times as heavy as quartz and other rock- minerals, quickly works its way to the bottom of the moving mass and ...

early as 1862. Attention later shifted to gold-bearing quartz veins with several vein occurrences developed by adits and pits (Figure 5). The Vancouver Island Gold Mine, one of five past gold producers in the area was first worked in 1895 when the original claims were staked. From 1896 to 1898 a relatively minor amount of tunneling was
