The Down The Hill vein occurrence is located on Grizzly Creek, a small eastward flowing tributary of the Apple River, at an elevation of approximately 1230 metres.
The area is underlain by the Jurassic-Cretaceous Coast Plutonic Complex, which comprises granodiorite, granitoid gneiss, amphibolite and schist. The metamorphic rocks generally occur as small, fault-bound pendants. Feldspar porphyry dikes are locally abundant.
The vein is described as a late and typically epithermal, vuggy, pyrite-bearing vein occurring adjacent to a late mafic dike. It is composed of white to clear vuggy quartz that commonly contains disseminations and ribbons of pyrite and minor sphalerite. The vein occurs singly or as stock works and is characterized by multiple stages of injection and brecciation. It is north- trending and steeply dipping.
In 1989, a sample (59017) yielded 4.5 grams per tonne gold and 0.13 gram per tonne silver (Assessment Report 20421).
The Apple occurrences were discovered as a follow up exploration program to the 1988 regional geochemical stream sediment sampling program in the Bute Inlet area. The Apple claims were subsequently staked by Placer Dome Inc. in 1989 and explored from 1989 to 1991. Exploration programs consisted of rock and soil sampling, prospecting and geological mapping. In 1997, Tiberon Mineral Ltd. prospected the Grizzly property as the Shannon claims. During 2010 through 2012, St. Elias Mines completed programs of rock, silt and soil sampling and 19 line-kilometres of combined ground electromagnetic and magnetic surveys.
