The Bill occurrence is located at the head of Hubert Creek about 11 kilometres due south of Telkwa. The ZNT property (093L 372) covers this showing and the Hubert (093L 226).
The showing area is underlain by Lower Jurassic Hazelton Group volcanics (Telkwa Formation) comprised of red to purple and dark green andesite and andesitic flows with interbedded tuff and agglomerate. The volcanics appear to be gently folded along a northwest axis which dips moderately southwest.
A weak shear zone about 76 metres wide trends 020 degrees and dips vertical. Mineralization, as exposed in trench, consists of finely disseminated to massive chalcopyrite with quartz infilling along fractures and faults within the sheared area. The hostrock is a massive dark green to black andesite. A visual estimate of the average grade across the 76 metre width was 0.15 to 0.20 per cent copper (Assessment Report 5162).
Other mineralization in the volcanics consists of disseminated pyrite, minor chalcopyrite and malachite staining.
In 1969, Searchlight Exploration Corp. flew a 1165 square kilometre airborne magnetic survey; no significant magnetic signatures were shown over the ZNT property area (Assessment Report 2508). In 1973, Maharaja Minerals completed a preliminary ground magnetic survey and soil (119), rock (3) and silt (12) sampling on the Hubert claim group (093L 226) (Assessment Report 4808). In 1974, Anglo-Bomarc Mines Ltd. performed 62 kilometres of ground magnetic survey and took 961 soil samples over the Jo-Bill claims (093L 244) (Assessment Reports 5156, 5162).
In 2012, Amarc Resources Ltd. acquired up to a 50 per cent interest in the ZNT property from Quartz Mountain Resources Ltd., which is the operator. In 2012, Quartz Mountain Resources Ltd. conducted soil and rock sampling along with an induced polarization (IP) survey on the ZNT property. A successful reconnaissance 256-sample soil geochemical program at ZNT was followed by a detailed 2223-sample soil geochemistry grid and a 20 line kilometre IP geophysical survey. A high contrast 1.8 by 1.2 kilometre silver-zinc anomaly was defined within an open-ended anomalous trend. This significant silver anomaly is in part coincident with an extensive IP chargeability anomaly. In July 2013, a pitting and trenching program designed to further refine the target was completed; about 170 rock and 36 soil geochemical samples were collected from 62 pits and trenches. Integration of the data from these surface programs has defined a sizable silver deposit target hosted by volcanogenic sandstones that will be the focus of a drilling program.
