The Mt. Manville showing is on an upper mountain ridge above the Taku River, approximately 9 kilometres upstream from the confluence of Taku and Tulsequah Rivers and 97 kilometres south of Atlin, B.C.

The Mt. Manville showing area is underlain by Carboniferous volcaniclastic and clastic rocks of the Stikine Assemblage.

Minor amounts of disseminated chalcopyrite and sphalerite were found in the rhyolitic rocks along the western edge of the claim. The rhyolitic rocks also contained some sericite and carbonate and in places were described as schistose. The andesitic rocks to the east were calcareous and the argillaceous rocks contained graphitic material and minor pyrite.

In 1983, a sample taken from the disseminated mineralization in the rhyolite assayed 0.0166 per cent zinc, trace lead, and 0.006 per cent copper (Assessment Report 11786).

Work History

In 1982, Cominco Ltd collected 70 soil samples at 25 metre intervals. Cominco’s work targeted an area on its Goat property that contained minor amounts of disseminated chalcopyrite and sphalerite in rhyolitic rocks along the western edge of the survey area. In 1983, Cominco conducted a 2.8 kilometre ground magnetic and Max-Min II (HLEM) survey, collected 55 soil samples and completed a mapping survey. The HLEM survey defined 4 conductive zones of which 3 were explained by graphitic argillite.

In the early to mid-2000s, the Surveyor area was staked as part of the Taku property owned by Optima Minerals Inc. The showing was not visited by Optima Minerals.

In 2012, Optima Minerals Inc. had an interpretation done on the results of government-funded regional geochemistry sampling, specifically stream sediment type, that occur on and around the Yellow Bluff Property, as well as government-flown gravity surveys over the property (Assessment Report 34484).
