The Stubb Lake occurrence is located on the east shore of Stubb Bay on the north side of Knewstubb Lake. The occurrence is comprised of three showings named, from north to south, the 3 Cube, Stubb South and Point. All showings are adjacent to the edge of Knewstubb Lake. Access is by the Nechako Reservoir road, also called the "500" Forestry road and then spur roads. These showings are 75 kilometres southwest of Vanderhoof. The area is underlain by Early to Middle Jurassic rock of the Hazelton Group.
The Stubb South is an area of propylitization, accompanied by silicification and pyritization that was found in 1993 to carry up to 4.5 grams per tonne gold (Assessment Report 24051). Anomalous gold is associated with quartz veins, stringers, stockworks and quartz breccia structures up to 3 metres wide, hosted in strongly propylitized feldspar porphyry, granodiorite and sediments. The Stubb South area includes the Camp, Grizley, 3-Cube and Point zones. The 3Cube Zone, which outcrops along the lake shore, is a well-developed, mineralized quartz breccia structure that is hosted in a complex section of strongly propylitized andesitic tuffs. Trenching during 1994 yielded up to 2.87 grams per tonne gold over 2 metres in an argillized shear zone (Assessment Report 24051). A single drill hole into this target intersected 6.1 metres of 0.5 gram per tonne gold (Assessment Report 24051). At the Point Zone, an outcrop of propylitized andesite contains a dense stockwork of quartz veins, surrounded by numerous angular boulders of similar material and a pyritic, silicified breccia. Trenching uncovered strongly propylitized andesite and a large area of pyritic fault gouge in basal till, however, the depth of overburden encountered suggests that the Stubb Point showing is probably not outcrop.
WORK HISTORY
In 1993 and 1994, the area from Knewstubb Lake north to Trout property, Cogema Resources carried out prospecting and regional till geochemistry, a 377 line-km DIGHEM airborne magnetics and EM survey (Assessment Report23096) followed by core drilling on the Trout prospect. Their work resulted in the discovery of several new prospects, including the Stubb gold prospect in the south-central part of the Property.
From 1995 to 1997, Phelps Dodge Corporation of Canada acquired the property and collected 1025 soil samples, completed rock geochemical sampling and 10.2 kilometres of IP surveying, followed by 615.4 metres of core drilling in four holes, also on the Trout prospect.
In 1995, Phelps Dodge Corporation of Canada, Limited performed geological mapping, prospecting, grid extension and soil sampling. Encouraging concentrations of gold were obtained from soils and rock float (up to 1.7 grams per tonne) collected from the Little Quartz Lake area. A total of 47.6 kilometres of grid lines were established through the south-central part of the claim block with grid lines spaced 200 or 300 metres apart covering the Stubb Bay and Lalinear areas. A total of 913 soil samples were collected. Approximately 25 square kilometres was prospected and geologically mapped at a scale of 1:20,000. Within the area soil sampled are several well defined gold soil anomalies. The largest of which extends northeast and southwest some 1800 metres across the grid area centred in the Little Quartz Lake area. Within the Stubb Bay area is a weak to moderately anomalous area in gold and arsenic located along the eastern side of the bay. These soil anomalies remain open to the southwest. The northern part of the grid centred in the Lalinear area shows numerous spot high gold values in soils within a much broader arsenic and mercury soil anomaly. Anomalous arsenic and mercury values within this soil anomaly are up to 85.2 parts per million arsenic and 165 parts per billion mercury. The coincident arsenic-mercury soil anomaly in the Lalinear area remains open to the northeast.
In 2006, Nechako Minerals Corp. acquired the property and completed a compilation and analysis of available regional magnetic, gravity and geochemical data. They then carried out a 63 kilometre IP survey over the central part of the claim group (Assessment Report 29890 and 32366)). In 2010, Nechako Minerals collected 40 soil samples on their Fish property.
In 2010, Nechako Minerals collect 40 soil samples on their Fish property.
In 2010, Kootenay Gold collected 31 rock samples east of the Fish Lake property of Nechako, between Chief Grey Lake and Stubb Bay.
In August, 2013, John Chapman and Trevor Davidge completed a one day reconnaissance of the Yennick Property. In 2014, John Chapman and Gerald Carlson conducted a regional and property scale structural analysis on their Yennik property which covered much of the area just north of Knewstubb Lake (Assessment Report 34875).
