Capsule Geology

The Albino Lake Project lies to the north west of the Eskay Creek deposit. The Alpha claims, which holds the Pix and Ridge showings, are immediately north of Little Tom Mackay Lake. The claims were explored by Eurus Resource Corporation in 1989 and 1990.

Regionally, the property lies within the Intermontane Tectono-stratigraphic Belt. The claims cover the contact between the Stikine Terrane, which makes up most of the western half of the Intermontane Belt, and the unmetamorphosed sediments of the Bowser Basin.

Locally, the area is underlain by mostly volcanic and sedimentary rocks of the Lower Jurassic Hazleton and Middle Jurassic Spatzizi Groups. The oldest mapped unit on the property consists of andesitic tuffs, agglomerate, and argillite of the Betty Creek Formation. The argillite is usually tightly folded, sheared, and locally siliceous and limonitic on weathered surfaces. The andesitic rocks are generally undeformed and unaltered. An exposure of rhyolitic ash tuff and shale tentatively identified as Mt. Dilworth Formation outcrops in the southern portion of the Alpha claim. This unit, 400 by 75 metres in size, appears to stratigraphically overlie the Betty Creek Formation. A large body of fine-grained and feldspar porphyritic diorite intrudes the Salmon River rocks in the central area of the Alpha claim. This elongated body is approximately 1200 metres long by 400 metres wide and trends northerly. Alteration assemblages noted on the property include limonitic staining in the argillites, patchy silicification, and weak chloritic alteration of the volcanic rocks of the Betty Creek Formation.

The Pix and Ridge showings both occur on the Alpha mineral claim, at the western edge of the Albino Lake Project and in the Betty Creek Formation. Mineralization at these showings on the Alpha claim consists of disseminated pyrite in the host rocks, with pyrrhotite, chalcopyrite, galena, bornite, and traces of arsenopyrite in the quartz veins. Secondary minerals in these zones include limonite, malachite, azurite, and covellite.

The Pix showing is part of a weak quartz vein stockwork system; approximately 50 metres of strike length in andesitic tuffs and plagioclase porphyry. It occurs adjacent to a 5 metre wide pyritic and strongly silicified argillite unit near the northern boundary of the Alpha claim. Six main quartz-sulphide veins, ranging up to 0.50 metre wide and 20 metres long, trend north-northeast, dipping moderately to steeply east. These veins contain up to 30 per cent pyrite, 50 per cent chalcopyrite, 2 per cent galena, and traces of bornite and covellite. These veins are typically leached with most pyrite oxidized to limonite and with abundant malachite staining. In 1989, rock chip samples from the showing assayed as high as 25 parts per billion gold, 226.6 grams per tonne silver, and 10.61 per cent copper (Chapman, J., (1990/05/09): Geological, Geophysical and Geochemical Compilation on Eurus Resource Corps. Albino Lake Project).

The Ridge showing is located approximately 550 metres west of the Pix showing in a similar geological setting. Siliceous rhyolite dykes intrude the diorite and andesites directly to the north. The host rocks near the mineralized zone are pyritic, partly leached, chloritic, and limonitic. The majority of the zone occurs as felsenmeer with boulders of massive sulphide more than 0.50 metre in width, containing 90 per cent pyrrhotite and 10 per cent bornite-covellite. Rock chips from the Ridge showing assayed as high as 65 parts per billion gold, 3.2 parts per million silver, and 0.85 per cent copper (Chapman, J., (1990/05/09): Geological, Geophysical and Geochemical Compilation on Eurus Resource Corps. Albino Lake Project).

Work History

No previous work is reported to have occurred on the Albino Lake claim group. In 1989, the exploration program of Consolidated Powergem Resource Corporation focused on a property wide program of mapping (1:10,000 scale), prospecting, rock (88 samples), soil (363 samples) and silt (58 samples) sampling was also undertaken to determine the stratigraphy within the property boundaries (Assessment Report 19606). An airborne geophysical survey (magnetic and VLF) was flown over the property totaling 1467 line-kilometres (Assessment Report 19456).
