While following up on anomalous stream sediment geochemistry in 1969, Colin Campbell located the areas now known as the A Zone and Campbell's Trench.

Falconbridge optioned the Col claims from Colin Campbell and conducted exploration programs in 1970 and 1971. This work consisted of soil geochemistry, geological mapping, a magnetometer survey, an Induced Polarization survey and diamond drilling. An access trail was also established that proceeded west along the north shore of Chuchi Lake, before proceeding north to the A Zone. Soil geochemistry outlined a signifcant copper anomaly over a broad area and a follow-up IP survey identifed a number of chargeability anomalies. The chargeability anomaly designated A had a coincident copper in soil anomaly and mineralization on surface. Diamond drilling outlined a historic (non 43-101compliant) resource estimate of 2-2.7 MT grading 0.6% copper at the A Zone.

Copper mineralization on the property was first discovered by Colin Campbell in 1969, while following up on anomalous steam sediment samples. The following year Falconbridge optioned the property and over the next two years completed IP and magnetic surveys, geological mapping, soil sampling and diamond drilling. This work identified the A Zone.

Additional exploration programs were completed by Kookaburra Gold Corp. from 1988 through 1991, Solomon Resources Ltd. From 2006 through 2008 and PEMC/Oz Minerals Ltd. From 2014 to 2015. All of these programs completed diamond drilling, geophysical surveys and geochemical sampling.

Mineralization on the property is most significant in three areas, 1) the A Zone, 2) Campbell Trench and 3) Slide Zone. 

At the A Zone, copper-gold mineralization occurs along a strike length of approximately 300 metres at an azimuth of 120o and where best developed it is approximately 30 meters wide over a length of approximately 175 metres. This zone was tested by a number of small diameter drill holes by Falconbridge in 1971 with the best intersections assaying 0.84% Cu over 45.7 meters and 0.70% Cu over 51.8 metres (DDH-1971-13 and DDH-1971-20, respectively). In 2007, Solomon Resources followed up with diamond drilling at the A Zone and demonstrated that mineralization extended at depth.

Until 2014, mineralization at the A Zone was believed to be associated with a shear zone, however while reviewing drill core from the A Zone, PEMC observed the presence of very well mineralized porphyry intrusions that are most likely responsible for the coper-gold mineralization due to their intimate relationship with quartz-sulphide veining and mineralization.

Campbell Trench Zone

Located approximately 1 km to the northwest and 150 m higher in elevation, the Campbell Trench Zone may be representative of a higher level within the porphyry-epithermal spectrum. This area is characterized by the presence of large quartz veins associated with copper-gold mineralization. Visible gold was observed in outcrop at this location in 2007.

One of the more intriguing examples of mineralization on the property can be found at the Slide Zone. Located approximately 1 km to the northeast of the A Zone, the Slide Zone occurs within Chuchi Lake Succession volcanic rocks and is characterized by a large area of boulders derived from a steeply dipping fault scarp. Select grab samples from the area in 2007 returned the following values:

17,700 ppm Cu, 948 ppb Au, 16.4 ppm Ag; Sample 96568
5,535 ppm Cu, 429 ppb Au; Sample 96571;
3,739 ppm Cu, 302 ppb Au; Sample 96570

In this area, mineralization is associated with strong epidote alteration and epidote magnetite/bornite nodules.
