Capsule Geology

The Otto West (Hunt Vein West) occurrence is located on the north side of Blackbear Creek, approximately 2.2 kilometres east of its junction with Spanish Creek.

The area is within the Quesnel terrane of the Intermontane Belt near its eastern margin, adjacent to the Precambrian to Paleozoic rocks of the Omineca terrane. The dominant lithologies comprise red-brown weathering phyllite, grey siltstone and interbedded felsic tuffs, which form the lowermost part of the Upper Triassic to Lower Jurassic Nicola Group. Formerly referred to as "black phyllite", this unit has been thrust onto the older rocks of the Omineca terrane, with which it has been deformed and metamorphosed, probably during the Middle to Late Jurassic.

Locally, a south west-dipping unit of graphitic argillite hosts several quartz-carbonate veins and quartz-carbonate flooded zones with sparse, patchy galena and pyrite mineralization and sericite alteration.

In 2008, a rock chip sample (86068) assayed 97.9 grams per tonne silver and 9.83 per cent lead over 0.15 metre (Turna, R. (2009-10-05): Technical Report on the Black Bear Property).

In 2010, a grab sample (H-31) from trench TR-15 on the Hunt West vein assayed 1420 grams per tonne silver and 51.2 per cent lead (Assessment Report 32209). Another sample (H-22) from a trench (TR-08), located a short distance to the northwest, assayed 180 grams per tonne silver and 57.9 per cent lead over 3 metres (Assessment Report 32209).

Work History

The area has historically been explored in conjunction with the Providence (MINFILE 093A 003) past- producing mine. In 1967, a program of regional prospecting and sampling was completed by the Keweenaw Sydnicate. In 1972, Stokes Exploration completed a program of soil sampling on the area as the BG claims. During 1987 through 1989, the Otto, China and Boomer claims were located to cover these veins and others recently examined. In 1989, Priority Ventures Ltd. drilled six NQ-size holes totalling 294.4 metres.

During 1996 through 2000, Barker Minerals Ltd. completed programs of prospecting, reconnaissance rock and stream sediment sampling, geological mapping and ground geophysical surveys on the area. In 2008, Barker Minerals prospected and sampled the area. In 2010, Barker Minerals Ltd. completed a program of sampling and 2000 metres of trenching in 12 trenches on the area.
