The Shar occurrence is located along the informally named Truce Creek in the Cassiar Mountains of northwest British Columbia near Iverson Creek, about 139 kilometres north of the community of Dease Lake.
The Shar property lies entirely within the Early Cretaceous Cassiar batholith, which comprises monotonously uniform, grey weathering, medium grained, massive to vaguely foliated, equigranular quartz monzonite with about 5 per cent biotite. Outcropping quartz monzonite is unaltered except by surface weathering, which is typified by chloritization of biotite and hematization of potassium feldspar. The quartz monzonite is cut by rare aplite dikes, which are all less than 20 centimetres wide and were only observed near Truce Creek. The quartz monzonite is well jointed on a series of widely spaced, easterly, southeasterly and northwesterly sets, which are observable in outcrop and on air photographs.
In 2009, three of four rock samples clustered at the centre of the Truce Creek showing contained visible galena within quartz vein(?) and/or strongly weathered quartz monzonite. Rock sample H885013 of weakly rusty weathering, weakly limonitic, highly weathered, dominantly quartz monzonite with trace galena assayed 943 grams per tonne silver, 1.59 per cent lead and 14.8 per cent zinc (Assessment Report 31557).
Between 1944 and 1967, the Geological Survey of Canada (GSC) completed geological mapping of the Jennings River (104O) map sheet. In 1978, the GSC conducted a low density stream sediment and water sampling survey on that map sheet as part of its Uranium Reconnaissance Program and the results of this survey were released in 1979 as Open File Report 561.
In 1979, Canadian Occidental Petroleum Ltd. staked the Shar 3-4 claims to cover a drainage from which the GSC obtained anomalous stream sediment results (3.5 parts per million (ppm) silver, 150 ppm lead and 380 ppm zinc). It added the Shar 9 claim to cover a nearby GSC stream sediment sample with high values for uranium and fluorine (82.8 ppm uranium and 270 parts per billion (ppb) fluorine). Semi-reconnaissance scale geological mapping, prospecting and stream sediment sampling was carried out by Canadian Occidental that same year. The 1979 stream sediment sampling surveys were unable to reproduce the GSC results; however, a sample collected from another creek on Shar 4 was somewhat more anomalous (4.2 ppm silver, 198 ppm lead and 390 ppm zinc). This anomalous creek is informally named Truce Creek. In 1980, Canadian Occidental carried out detailed stream sediment sampling on Truce Creek. Having received positive results from this work, the Shar 11 claim was staked to cover potentially mineralized ground in the Truce Creek area. Geological mapping, prospecting and stream sediment and soil sampling were then completed in the area. Stream sediment samples with elevated values for silver, lead and zinc were located near the headwaters of Truce Creek and persisted downstream. Prospecting in and around the creek revealed rare, small cobbles of hydrothermally altered, pyrite-bearing(?) granitic rocks. These rocks contained no visible economic sulphides, yet returned values of 3 to 34 ppm silver, 285 to 3000 ppm lead, 84 to 5700 ppm zinc, and up to 150 ppb gold. Soil geochemical sampling revealed two zinc anomalies. One anomaly covers a 200 by 400 metre area to the west of Truce Creek, while the other anomaly straddles Truce Creek and is defined by a 400 by 800 metre area of anomalous zinc with sporadic silver and lead values. Canadian Occidental subsequently allowed the Shar claims to lapse and Strategic Metals Ltd. staked the Shar 1 mineral tenure in 2005.
In 2009, a field program conducted on behalf of Strategic Metals Ltd. comprised prospecting and deep auger soil sampling. Six rock samples and an additional five stream sediment samples and 92 soil samples were collected.
In 2015, geochemical sampling (72 grid soil samples) and prospecting was completed on behalf of Strategic Metals Ltd.
