The region of the Jesse showing is underlain by the Jurassic Hazelton Group, dominated by intermediate flows and volcanic rocks of the Lower Jurassic Telkwa Formation, which is overlain or in fault contact with volcaniclastics of the Smithers Formation. The strata are intruded by a quartz diorite stock of the Late Cretaceous Bulkley Plutonic Suite.

A subcrop of chalcedonic quartz vein and pyritic rhyolite and small pieces of proximal quartz with pyrite and chalcopyrite material yielded 0.74 gram per tonne gold and 57.2 grams per tonne silver; another sample (PS-130) assayed 0.028 per cent molybdenum (Assessment Report 21720).

Work History

Mineralization on the Tar and Jesse region was discovered in 1981 by Pat Suratt and the reader is pointed to the MINFILE Cummins Veins prospect (093E 100) for details of the earliest area work history. The Tar and Jesse claims were part of the Cummins claim group in the 1980s to early 1990s. In 1991 two prospectors collected 37 rock samples and 5 gold-pan concentrates in the Tar and Jesse areas which led to the recent documentation the two showings.
