Mineralization was discovered at the Santana occurrence in 1916. The owners conducted trenching and drove several adits. A shipment of hand-sorted ore was made from one of one of the adits. The shipment of 158.8 tonnes was made to the Granby smelter at Anyox in 1916, which produced 93 grams of gold, 14,370 grams of silver and 4779 kilograms of copper. High grade ore was stockpiled from an offshoot for shipment, however the company could not raise funding to open a mine.
The property lay inactive until 1964 when surface work and diamond drilling was conducted by R. Renshaw. Four holes were drilled totalling 762 metres. Between 1987 and 1989, Lonsdale Capital Corporation had an option to earn 100 per cent interest in the Santana property. All four holes drilled under the mineworkings were assayed, an analysis of the entire core assayed 0.25-0.3% copper according to historic documentation and old geologist reports.
The main mineralization occurs in a narrow zone of contact metamorphosed rocks along the limestone and quartz diorite contact, which is traceable along ground exposures for up to 600 metres length, along a northwest trend, and widths averaging 12 metres, but ranging from 10m - 25m wide and depths of over 260m. The granodiorite is faulted and fractured and has been described as having a "gneissic structure". The limestone is grey to bluish black in appearance. The metamorphosed limestone is dark brown,
rusty, quite often heavily mineralized, in places broken and quartz-filled, rarely coarsely crystalline, and has the general appearance of a skarn.
Mineralization, in the form of chalcopyrite, pyrrhotite and pyrite, occurs in masses or short lenses. Malachite and azurite are noted as alteration minerals. Many rock samples taken in 1988 yielded anomalous copper, zinc and silver values (Assessment Report 17256). Sample 9606-002, taken in 1988, yielded 5.65 per cent copper, 0.41 per cent zinc and 69.60 grams per tonne silver. The sample was taken from a 5-centimetre wide quartz
vein with chalcopyrite.
Sample 9609-016 yielded 12.00 per cent copper, 0.44 per cent zinc and 1213.79 grams per tonne silver. The sample was
taken from massive sulphides at the workings.
Recent property work has reported chalcopyrite as fine-grained disseminations to massive blebs to stockwork-type narrow veinlets with secondary silica within quartz diorite. The mineralization appeared to be structurally controlled along the intrusive-limestone contact. Three samples were taken near the No. 1 adit. Sample 01454 yielded 0.94 per cent copper, 12.75 grams per tonne silver and 0.17 gram per tonne gold. The sample was a 1.8-metre chip across the centre zone above the No. 1 portal. Grab sample 01455 yielded 2.74 per cent copper, 7.20 grams per tonne 01456, from a series of sloughed trenches, yielded 3.92 per cent copper, 290.33 grams per tonne silver and
0.21 gram per tonne gold (Assessment Report 19037).
In recent days 911 Exploration Corp has entered into an LOI with Kermode Resources Ltd and carried out several days of exploration work including taking 24 samples from various areas on the property, including a 5.15m chip sample of semi massive and massive sulphides near adit #2.
