Capsule Geology

The Lehto area is underlain by a sequence of marine sedimentary and volcanic rocks of the Upper Stuhini Group. The stratigraphy has been intruded by Early Jurassic granodiorite to syenite.

The Lehto showing is located on the east side of Lehto glacier consists of a mineralized quartz-carbonate stockwork in a felsic volcanic rock. Quartz vein stockwork at the Lehto showing contains 3 to 5 per cent sulphides (pyrite-chalcopyrite-galena) across a zone 2 to 3 metres wide, exposed for 50 metres with probable strike extension under ice.

The largest of these veins is 10 centimetres wide and is part of a stockwork veining zone 2 to 3 metres wide extending 50 metres to a point where it disappears beneath the ice. The zone strikes 160 to 170 degrees with a steep east dip. This gossan is located near the contact between intrusive granitoids and overlying volcanics. A 10-centimetre-wide unit of marble is interbedded with the volcanics at this locality but contains no visible sulphides. Gold values range from 50 to 980 parts per billion in samples that contain stringers and disseminations of pyrite-galena-chalcopyrite (1 to 5 per cent) (Assessment Report 20737).

In 1990, the MacGold 3 to 5 claims were owned by Ecstall Mining Corp. and Omega Gold Corp and under option to Golden Arrow Resources. The work consisted of reconnaissance mapping and extensive rock geochemical sampling (124 rocks) from several prominent gossans and mineral occurrences.

In 2006 and 2007, Hathor Exploration Ltd. completed a 7228.7 line-kilometre airborne geophysical survey on the area as the Snip claims of the Iskut project. In 2008, Max Minerals Ltd. examined the property.

In 2013, on their SK claim, Green Swan Capital collected 5 rock samples about 500 metres east of the Lehto showing and 2 rocks samples 2 kilometres east-northeast of the Lehto showing. Assays were not significant.

By 2020, claim ownership of the following showings, Lehto (104B 543), MacGold 4 (104B 544) and MacGold 3 (104B 545) was held by Garibaldi Resources.
