The ZNT occurrence is located south of the Bulkley River about 20 kilometres south-southeast of Smithers or 8.5 kilometres south of the community of Telkwa. The ZNT property also hosts two historical MINFILE occurrences, Hubert (093L 226) and Bill (093L 244).

The showing area is underlain by Lower Jurassic volcanic rocks of the Telkwa Formation and sedimentary rocks of the Nilkitkwa Formation, both of the Hazelton Group. A northwest trending fault contact placed coarse clastic sedimentary rocks of the Lower Cretaceous Red Rose Formation (Skeena Group) on the east. This fault contact bisects the grid area into two equal halves. Middle to Late Cretaceous Bulkley Plutonic Suite intrusive rocks occur at the western edge of the property. The Bulkley intrusions include granodiorite to quartz diorite, porphyritic granodiorite, and quartz monzonite.

A poorly sorted, polylithic conglomerate outcrop (sample 988128) yielded 0.44 per cent zinc and 6.6 grams per tonne silver (Assessment Report 34152). This coincides with anomalous silver, zinc and arsenic concentrations in soil and is situated peripheral to a high apparent chargeability anomaly. A sample (988129) of plagioclase-phyric clastic rock assayed 0.31 per cent zinc and 4.9 grams per tonne silver (Assessment Report 34152). A sample (988130) from plagioclase-phyric andesite assayed 0.058 per cent lead, 0.36 per cent zinc and 2.5 grams per tonne silver (Assessment Report 34152). The three samples are separated by distances of from 1.4 to 1.8 kilometres.

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.
