The Debenture (Lot 6310) and five other Crown grants (Lots 6311–6315) are located on the south side of Debenture Creek, on the northeast boundary of Babine Mt. Park.
The claims are underlain by Lower Jurassic Hazelton Group volcanics of the Telkwa Formation comprised mainly of andesite, rhyodacite flows, breccia and tuff. The volcanics are intruded by a Late Cretaceous quartz diorite sill about 6 metres thick that strikes northwest and dips between 40 to 45 degrees to the southwest. The intrusion cuts chlorite-epidote altered lapilli tuffs.
Mineralization consists of fracture fillings in the numerous fault/fracture systems in the volcanics. The No. 2 vein occurs in a fracture that crosscuts the bedding and dips 78°. The volcanics are sericitized and partly silicified and host mineralized seams and fairly massive bands of disseminated galena with minor sphalerite. The vein is mineralized with galena seams and stringers within brecciated vein quartz and wallrock.
The No. 1 vein is exposed in a steep inaccessible bluff and dips 75° south. It was traced intermittently for 61 metres.
The property was originally staked in 1913 and a single crosscut tunnel was driven in 1917. Exploration was continued by Wanda Mines and Explorations Limited in 1966 with a geological mapping program. A grab sample of the vein material, representative of about 0.45 metres of the crosscut tunnel, assayed 1530 grams per tonne Ag, 17.40 per cent Pb, 6.95 per cent Zn and 0.08 per cent Cu (Property File Cyprus Anvil Mitchell, J.A., 1966). ”
