Work History

Staked as Guano, etc. cl (YA00242) in Jul-Sep/76 by Ukon Joint Venture (Chevron and Kerr Addision), which explored with mapping, geochem and radiometric surveys in 1976 and a ground scintillometer survey in 1979. Restaked as PS cl (YB00978) in Aug/87 by Mountain Province Mining Inc.  In 2010, soil sampling was carried out near the occurrence and a helicopter radiometric survey was flown over the entire property.
 
Regional Geology
 
The occurrence is located on the Cassiar Platform, a curvilinear shelf that formed in the early Paleozoic, roughly parallel to the western margin of the North American craton but separated from it by the Selwyn Basin. Shallow marine miogeoclinal sediments were emplaced on the platform until Late Devonian time. Block faulting and local uplift during the Late Devonian and Mississippian resulted in deposition of carbonaceous shale and chert pebble conglomerate in the Selwyn Basin and across the platform. Local explosive volcanism produced volcaniclastic material and flows of the Pelly Mountains volcanic belt. The belt comprises localized submarine volcanic centres generated in an extensional environment that are separated by basins in-filled with sediments and volcaniclastic rocks. Several cogenetic syenite and trachyte domes and small stocks are the remains of vent areas. Subsequent deformation is a result of Mesozoic thrust faulting related to the Cordilleran orogeny, emplacement of Cretaceous intrusions and Tertiary strike-slip movement along the major northwest-trending Tintina Fault, 30 km to the northeast.
 
 
Property Geology
 
The occurrence was first identified as Trip in AR 095343. This showing consists of a number of small parallel dyke outcrops up to 4 m wide that trend 020 degrees. The dykes are fine-grained with disseminated magnetite or pyrite. Within the dykes there are some small quartz veins with accessory fluorite.
 
The Trip Showing is associated with a short strike length soil sampling anomaly. Several grab samples collected in 2010 returned anomalous values, e.g., sample 334007 assayed 1.78% TREO, 1.76% ZrO2, 0.50% Nb2O5 (AR 095343).
