Capsule Geology

The Glean showing is located 30 kilometres west of Atlin, on the east side of Taku Arm near Gleaner Mountain, 6 kilometres south of Bee Peak. There are several other occurrences on the Golden Bee property (104M 076 to 080).

The area, bounded by faults, is underlain by sediments of the Lower Jurassic Laberge Group. These comprise greywacke, argillite, shale and conglomerate intruded by granite near Bee Peak. The Llewellyn fault is 2 kilometres to the west and separates these rocks from the Coast Plutonic Complex. To the east, the Nahlin fault separates the rocks from the Cache Creek Group. The area of the showing contains splays from these major faults. The bedding generally trends north to northwest.

At the Glean showing, mineralization is hosted in rhyolite, basalt, andesite and tuff of the Paleocene Tagish Volcanic Suite.

Mineralization occurs in several silicified shears, 1 to 8 metres wide, displaying parallel, stacked and en echelon zoning. Mineralization, as sparse disseminations and concentrations of up to 40 per cent, consists of pyrite, arsenopyrite, chalcopyrite, galena and pyrrhotite. Sulphides, 1 per cent or less, also occur within large altered units of andesite and rhyolite. A copper zone has been identified by malachite staining on the east face of the rhyolite talus. Alteration consisting of silicification +/-chlorite and sericite is associated with mineralized zones.

Samples were taken from the altered contact zone between andesite and banded brecciated rhyolite flows of uncertain age. The zone, 1 metre wide and exposed for 75 metres in length, trends north-south and dips 50 degrees east.

The highest sample (89-5R03) assayed 3.2 grams per tonne gold, 58.9 grams per tonne silver, 0.095 per cent copper, 0.986 per cent lead, 0.203 per cent zinc, 8 per cent arsenic and 0.06 per cent antimony (Assessment Report 19631). Samples in 1990 confirmed these values and further delineated the zone (Assessment Report 21327).

Work History

The claims were staked by Golden Bee Minerals in 1989. Golden Bee Minerals conducted a program of sampling, mapping, prospecting and geochemical surveys in 1989 and 1990.

The Glean area was prospected in 2012 by Momentum Minerals when it was determined that part of the showing appeared to be within its Llewellyn property (Assessment Report 33560): "The Glean prospect appears to be a mineralized volcanic vent consisting of argillically altered and brecciated rhyloite and hydrothermally altered andesite adjacent to mineralized bedded volcanic flows. The rhyolite breccia is the youngest of all the volcanics at the Glean prospect. The rhyolite is certainly altered but, other than pyrite, does not appear to be well mineralized. This observations was made by examining talus float downhill of the Glean Prospect. Better mineralized dark green/black volcanic flows in the vicinity of the vent showing blebs chalcopyrite and pyrrhotite along with chlorite altered, polymictic flows containing pyrite fragments, may be indicative of a copper porphyry system at depth."

Refer to Bee Lake S6 for details of the southeast portion of the Llewellyn property.
