Airborne Magnetic Survey - (1^st vertical derivative) map.

Lineaments were identified using a combination of the TMI, 1^st vertical derivative, and the Analytic Signal products. Three sets of lineaments are identified, 1) structures parallel and subparallel to the Brett Main zone that trend NNW-SSE, 2) structures oriented ENE-WSW that dominate the northern part of the survey, and 3) structures oriented ESE-WNW that dominate in the southern part of the survey.

The lineaments in Set 1 are of interest as they are magnetic lows within higher magnetic areas that possibly reflect de-magnetized zones related to hydrothermal alteration. This pattern is similar to that around the Main zone. The NNW to N trending lineaments west of the Main zone are targets for further exploration work such as geochemical soil or biochemical bark surveys and IP geophysical surveys.

The Brett Gold Project

A total of 160 surface diamond drill holes (20,945 meters) and several reverse circulation holes have been completed since the initial discovery in 1983. This work has defined a total of 13 mineralized zones, including the TR-21, Bonanza Zone, RW vein, Tuff Zone and North Extension Zone along the Main Fault Zone, with parallel zones including the TR-1, Stockwork, 490 and Border zones. East of these are the New Discovery and East Zones, and bordering the vein zones on the east and west are large areas of altered rocks with gold geochemical anomalies named Gossan and West Zones.

In the 1990's a 291 tonne surface bulk sample was shipped to the smelter at Trail, BC that averaged 27.74 grams per tonne gold and 63.7 grams per tonne silver (Brett 2017 NI 43-101 report). In the mid-1990's, a Mine Adit and underground drift and raise development was done to access bonanza grades intersected in surface drill holes. High-grade vein mineralization within the Bonanza Zone was encountered, disrupted within the Main Fault Zone. In 1995, metallurgical test work was done on a 4 kg sample with a head grade of 20.3 grams per tonne gold and 50.3 grams per tonne silver. Flotation of gravity concentration tails resulted in overall gold and silver recoveries of 91.3% and 72.8%, respectively (BC Assessment Report 25351).
