Capsule Geology

aThe area is underlain by Lower Jurassic Hazelton Group, Telkwa Formation volcanics comprised mainly of variegated red to green breccia, tuff and flows of basaltic to rhyolitic composition. These volcanics are intruded by a Late Cretaceous to Tertiary felsic intrusion.

A copper-silver occurrence is shown on Map 69-1 near the contact between the intrusion and the Telkwa volcanics.

In 2004, Regis Plante discovered chalcopyrite and malachite in a brecciated fault zone in a greyish red felsic volcanic host, poorly exposed in a small creek. The main malachite zone is approximately 5 centimetres in width. Also present were iron oxides, dendritic manganese oxides, calcite and an iron carbonate mineral in fracture fillings and disseminations. The mineralized fault may be controlled by a bedding plane and may strike about 290 degrees and dip approximately 45 degrees south.

Work History

Local small fracture fillings of copper minerals were found in felsic volcanic rocks within the area of the claims during logging road construction in the 1990s. The showings were staked by Harold Thomas Hendrickson, under whose direction a flagged grid was prepared in the area of the showings. A VLF-EM survey was conducted over the grid and some short diamond drill holes were put down.

The claims lapsed and the area was staked by Regis Plante in 2001 (Willy 1-4) and 2002 (Regis 1-15). During the 2002 field season, Mr. Plante drilled two short diamond drill holes in felsic volcanic rocks to test a VLF-EM anomaly. A conductive fault was intersected in one of the holes, but the test would have benefited from a longer hole. Further ground VLF geophysics confirmed the previous VLF-EM anomaly and eleven reconnaissance silt and soil samples in the same general area, some of which carried anomalous amounts of lead (up to 124 parts per million) and zinc (up to 552 parts per million), or silver (up to 3.6 parts per million), copper (up to 97 parts per million) and molybdenum (up to 6 parts per million) (Assessment Report 27515).

In 2004, exploration on the Regis mineral claims occurred comprised prospecting, grid preparation and the collection of 34 silt and 138 soil samples. This work was mainly directed to further the exploration of areas in which reconnaissance geochemical sampling had returned anomalous amounts of precious and base metals in soils overlying felsic volcanic rocks.
