The Belvidere (L.301) and Tortilla (L.536) occurrences are located approximately 2 kilometres north of the mouth of a creek flowing into Snug Basin.
The area is underlain by a narrow north trending band of Upper Triassic Quatsino Formation (Vancouver Group) limestone. The band is in contact on the west with Karmutsen volcanics (Vancouver Group), and on the east with Lower Jurassic volcanics (Bonanza Group). The strata is intruded by diorite and granodiorite of the Early to Middle Jurassic Island Plutonic Suite.
At the Belvidere (L.301) occurrence a 0.05 metre thick, rusty and vuggy copper skarn vein, oriented at 305 degrees strike and dipping 70 degrees northwest, is exposed over 10 metres length. The skarn is hosted by a felsic intrusive and contains chalcopyrite and pyrite with garnet. In 2007, a select outcrop grab sample (362657) assayed 1.52 per cent copper and 5 grams per tonne silver (Assessment Report 29574).
At the Tortilla (L.536) occurrence, located approximately 200 metres north, a 1.5 metre thick, foliated, fractured and vuggy iron-copper skarn zone, oriented at 155 degrees strike and 60 degrees dip to the south west, is exposed over a 15 to 25 metre strike length. The skarn zone is hosted by a mafic intrusive and contains magnetite with sulphide fractures and in-fillings including pyrite, chalcopyrite with garnet and epidote. In 2007, a select outcrop grab sample (362658) assayed 3.42 per cent copper and 3.5 grams per tonne silver (Assessment Report 29574).
The area was originally explored in 1899 and 1916. An old adit occurs on the Tortilla (L. 536) crown grant from this time. In 1965, Alberni Mines completed a program of geological mapping, geochemical sampling and a ground magnetometer survey. In 1967, Mt. Agnes Mines completed a ground magnetometer survey on the area. In 1969 and 1970, Nootka Explorations completed a program of rock and soil sampling, geological mapping and a ground magnetometer survey on the area as the Henderson property.
In 2007 through 2013, Nahminto Resources completed a program of prospecting, geological mapping, geochemical sampling, a ground magnetometer survey and airborne geophysical surveys on the area as the TJM claims, part of the Nahmint property.
