The NTI (M8) occurrence is located at an elevation of approximately 520 metres on a northeast facing slope, southwest of the Chemainus River and approximately 9 kilometres north-northwest of the community of Lake Cowichan.

Regionally, the area is underlain by chert, siliceous argillite and siliciclastic rocks of the Mississippian to Pennsylvanian Fourth Lake Formation (Buttle Lake Group), calc-alkaline volcanic rocks of the Middle to Upper Devonian Nitinat Formation (Sicker Group) and volcaniclastic rocks of the Middle to Upper Devonian Mclaughlin Ridge Formation (Sicker Group). These rocks are intruded by granodiorite and quartz diorite of the Early to Middle Jurassic Island Plutonic Suite and gabbroic to dioritic rocks of the Triassic Mount Hall Gabbro. The sediments and pyroclastics are silicified and hornfelsed near the intrusive contact. Undivided sedimentary rocks of the Upper Cretaceous Nanaimo Group locally overlay the previous units.

In the occurrence area the Sicker Group in the is comprised of cherty tuffs to agglomerates of the Upper Devonian McLaughlin Ridge Formation. The Buttle Lake Group comprises chert, argillite, siltstone, sandstone, conglomerate and minor limestone with pyroclastic flows of the Mississippian to Pennsylvanian Fourth Lake Formation, and limestone, marble with minor chert, argillite and sandstone of the Upper Pennsylvanian to Lower Permian Mount Mark Formation. The contacts between these formations appear to be fault related. The rocks are weakly regionally metamorphosed, probably to lower greenschist facies, and are folded along a northwest-trending fold axis.

Locally, a small vertical shear in a mixed area of siltstone, sandstone, argillite and greywacke hosts narrow quartz veins with pyrite and chalcopyrite mineralization.

In 1984, a rock sample (R-68126) from the shear assayed 3.05 grams per tonne gold, and a nearby undescribed sample (R-68127) yielded 0.44 gram per tonne gold and 0.23 per cent copper (Assessment Report 12606).

In 1986, a rock sample (14508) of mineralized quartz vein material assayed 0.30 gram per tonne gold (Assessment Report 15578).

Work History

In 1983 and 1984, Noranda Mining and Exploration Inc. conducted programs of geological mapping and geochemical (rock, silt and soil) sampling on the area as the NTI 1-4 claims.

In 1986 and 1987, International Cherokee Developments Ltd. conducted a program of geological mapping, trenching, geochemical (rock, silt and soil) sampling, a 4.3 line-kilometre ground magnetic and electromagnetic (VLF) survey and four diamond drill holes, totalling 353.0 metres, on the area as the Mike property.

In 2010, Rock-Con Resources Inc. completed a program of remote sensing analysis on the area.

In 2021, Crest Resources Inc. conducted a program of prospecting and geochemical (rock, silt and soil) sampling on the Sognidoro property. In 2022, Reverend Mining Corp. completed a further program of prospecting and geochemical (rock, silt and soil) sampling on the Sognidoro property.
