The Dave's Knoll showing area is underlain by andesitic rock of the Lower Jurassic Unuk River Formation of the Hazelton Group. The Texas Creek Plutonic Suite comprises a group of Early Jurassic granodioritic stocks, dikes, sills and a batholith in the area.
‘Dave’s Knoll’ refers to an area along the break in slope on the east side of the Bowser River, approximately 1 kilometre to the northeast of the old Eastgold mine (MINFILE 104B 033). In 2005 Rimfire Minerals Corporation and Serengeti Resources Incorporated collected samples that yielded interesting gold values associated with highly anomalous values of molybdenum (up to 172 parts per million). Several other samples that were gold-poor yielded very highly anomalous values of lead and zinc. Sample 275502 from a gossanous knoll in sedimentary rock assayed yielded 1.62 grams per tonne gold and 7.6 grams per tonne silver (Assessment Report 28012).
In 1990, Claimstaker Resources first sampled Dave's Knoll obtaining high gold and silver from the strongly gossanous zone along the western boundary of their Arc 30 claim. (Assessment Report 21170). The area was described as altered siltstones that were silicified and sericitized and accompanied by 1 to 10 per cent pyrite plus/minus arsenopyrite as disseminations and fracture fillings with quartz and weak carbonate.
