The Copper Pendant property is adjacent to Granby Bay on Observatory Inlet, near the historical mining town of Anyox.

The region is underlain by a roof pendant, consisting of volcanic and sedimentary rocks, within the Eocene Coast Plutonic Complex. These pendant rocks have been correlated with Middle-Upper Jurassic Hazelton Group rocks and overlying upper Middle to Upper Jurassic Bowser Lake Group sedimentary rocks (Geological Survey of Canada Open File 3453). The Hazelton rocks consist of variably chloritized pillow and massive andesite and basalt with minor mafic tuffs. The overlying Bowser Lake sediments consist of argillite, siltstone and sandstone with minor chert and limestone. There are two observable phases of folding in the area, an initial north-northeast trending phase followed by a later east-northeast trending phase.

A 2007 drillhole (CP07-04) was designed to target a strong AeroTEM anomaly with a coincident magnetic high. The hole is collared in sediments and crosses the contact into basalt at about 165 metres. The drillhole intersected weak mineralization while in the sediments with pyrrhotite stringers amounting to 10 per cent of the rock volume and trace chalcopyrite. Small blebs of sphalerite were noted from 90 to 98 metres. Anomalous sample ranges include 6 metres of 1616 parts per million zinc and 104 parts per million copper at 61 metres; one sample containing 2433 parts per million zinc at 105 metres, and one sample containing greater than 10,000 parts per million (>1 per cent) zinc at 90 metres (Assessment Report 30606).

In 2006-07, SNL Enterprises Inc. conducted a multidisciplinary, reconnaissance, first phase exploration program comprising airborne geophysics, stream geochemistry and limited geological mapping. This initial work facilitated a follow-up second phase of work in 2007 that included more detailed geological mapping, continued stream sediment sampling, prospecting and a small amount of diamond drilling. During the exploration programs, the following work was conducted: 1154 line kilometres of airborne EM and magnetics (AeroTEM); four diamond-drill holes totalling 1143 metres; 546 stream silt samples; 28 heavy mineral samples; and 217 rock, lithogeochemical and core samples.
