The Baker occurs on the north side of Stuhini Creek, highlighted by a distinct yellowish alteration zone within rocks of the Early Eocene Sloko Group. The vertical exposures on the north side of the creek are limonitic stained and gossanous with pervasive sulphide mineralization and strongly silicified. Locally, felsic volcanics exhibit a tuffaceous texture and may be rhyolite tuffs. Quartz-eye rhyolite tuffs with pervasive sulphide mineralization (>5 per cent finely disseminated pyrite) occur on the west side of the tributary near the confluence with Stuhini Creek. Also occurring nearby are sulphide-rich rhyolite tuff breccias composed of large, angular, dark grey fragments hosted in a silica-sulphide matrix. Locally, the wallrock along the drainage is sheared and slickensided with extensive limonite and manganese oxide staining. A sample of the intermediate, silicified and pyritic pyroclastic from this alteration zone assayed trace gold, 1.37 grams per tonne silver, 0.01 per cent copper, 0.02 per cent lead, and 0.01 per cent zinc (Assessment Report 8932). Wesa (Assessment Report 20324) states that the zone of interest exhibits “advanced argillic alteration with local intense silicification and pervasive pyritization and gossanous limonitic surface weathering. The strong, pervasive silicification of the felsic volcanics...may represent the silica cap covering an epithermal system.”

In 1981, prospecting was carried out on the alteration zone by Comaplex Resources International Ltd. on the Hini claim which covered the occurrence (Assessment Report 8932) In 1990, a five man crew including geologist was prospected the Baker property for owner Erik Bergvinson. Analysis of 14 rock and 77 soil samples yielded low values but area alteration has an “epithermal character” (Assessment Report 20324). In the early to mid 2000s, the Baker area was staked as part of the Taku property owned by Optima Minerals Inc. The Baker showing was visited during 2006 at which time a felsic intrusive/rhyolite outcrop containing quartz eyes was sampled at UTM coordinates 6496000 North, 596000 East. The sample was weakly anomalous in silver.
