The area is underlain by quartz monzonite and quartz feldspar porphyry, which are probably genetically related to the Sloko-Hyder Plutonic Suite Tertiary age. These rocks are cut by monzonite, diorite, and aplite dykes. Northwest trending structures control alteration, quartz veining and mineralization.
The quartz monzonite, consisting mainly of hornblende, biotite and feldspar, sometimes has zones of sericite-clay-chlorite-iron oxide alteration. An area of potassium feldspar-quartz veins within a strongly sheared, altered and leached zone, measuring 600 by 50 metres, striking 125 degrees and dipping 55 degrees southwest, contains bornite, chalcocite, malachite and minor molybdenite. Aplite dykes are often parallel to or occupy the same structure.
A selected sample from a 20 centimetre quartz vein assayed 35 per cent copper, 0.003 per cent molybdenum, 251 grams per tonne silver and 0.55 gram per tonne gold. A 9.1 metre chip sample assayed 1.18 per cent copper, 11.0 grams per tonne silver and 0.96 gram per tonne gold. Four hundred metres to the south, a 6.1 metre chip sample assayed 0.335 per cent copper. (Assessment Report 8962).
In 1980, an exploration program was carried out by Utah Mines Ltd. on the Val 1 and 2 claims to delineate the shear zone containing chalcocite, bornite, molybdenite and precious metal mineralization.
The ground was restaked in 1987, as the Sal property by Tahltan Holdings Ltd. On behalf of Tahltan, Stetson Resource Management Corp. carried out an exploration program. Geological mapping was carried out over the center portion of the property at a scale of 1:5,000 and at larger scales where mineralization was discovered. Rock chip sampling of quartz veins, and all pyritic rocks was carried out. Soil and talus sampling was carried out at 2 meter intervals on lines spaced 25 meters apart covering the shear zone on the Sal 2 claims.
