The Weber (Par) occurrence is located on the west bank of Wasi creek, 2 kilometres from its confluence with the Osilinka River, approximately 43 kilometres north-northwest of the community of Germansen Landing. The property was explored by Suzie Mining Exploration during the 1970s as part of the Wasi Lake project, this included the Wasi-Beveley (094C 023) and Carie (094C 130) occurrences, located 3 kilometres north-northwest and 2 kilometres south-southwest, respectively.

The area of the Par prospect is underlain by a north trending carbonate sequence comprising the Lower Cambrian Mount Kison Formation (Atan Group) and the Cambrian to Middle Devonian Razorback, Echo Lake and Otter Lakes groups. This sequence, interbedded with thin horizons of shale, argillite and coarse-grained clastics, overlies basal orthoquartzite, siltstone, sandstone and shale of the Mount Brown Formation (Atan Group) and is overlain by 400 to 500 metres of Upper Devonian to Permian Big Creek Group shales.

Four forms of mineralization have been reported as follows (Assessment Report 21809, page 5): (1) The Weber showing, comprising dolomite-hosted replacement-type pyrite, galena, sphalerite and barite is stratigraphically inferred to occur within the Mount Kison Formation. The minerals occur as disseminations and "seams" several centimetres wide. A sample taken across 5.18 metres from an opencut assayed 0.69 gram per tonne gold, 34.29 grams per tonne silver, 1.6 per cent lead and 3.6 per cent zinc (Minister of Mines Annual Report 1930, page 153). (2) Trenching on the property revealed thin lenses (less than 0.4 metre) of 60 to 80 per cent sulphide rock intercalated with shales, phyllites and dolomite boudins of the Cambrian to Ordovician Razorback Group. Three trenches, in line and up to 800 metres to the southeast of the Weber showing, yielded the following results: i) 6.7 per cent lead and 2.5 per cent zinc over 4 metres (Trench 1); ii) 1.1 per cent lead and 3.2 per cent zinc over 18 metres (Trench 3) and; iii) 6.1 per cent lead and 3.4 per cent zinc over 1 metre (Trench 5) (Assessment Report 21809). (3) Galena, sphalerite and barite associated with secondary dolospar veining is evident throughout the dolomite of the Middle Devonian Otter Lakes Group. (4) Ordovician to Lower Devonian Echo Lake Group carbonates were found to host galena and sphalerite as pods and small (less than 0.5 by less than 0.1 metre), thin, low-grade lenses of solution-etching and replacement-type deposits.

The earliest recorded work in the area was reported in the Minister of Mines Annual Report 1930 documenting the Weber prospect, located near the northern edge of the present Wasi Creek property. The Weber prospect was restaked and worked intermittently following the discovery and described in the 1954 Geological Survey of Canada Memoir 274.

In 1990, Cominco Ltd. completed a reconnaissance silt and soil geochemical survey on the stratigraphic extensions of the Lower Cambrian to Middle Devonian carbonates that host the known mineral occurrences. The area around the Weber prospect was highly anomalous so Cominco staked their first two claims covering this prospect and the anomalous areas. Cominco then completed contour and grid soil sampling and outlined a large, highly anomalous area 1.0 by 4.5 kilometres in size in lead, zinc, iron and silver and staked five additional claims. Cominco Ltd. completed an extensive exploration program during 1991. The exploration program consisted of geological mapping, soil sampling, airborne electromagnetic (EM) and magnetometer surveys, ground geophysical surveys including HLEM, magnetometer, induced polarization and VLF surveys. A trenching program was completed on the target area of the large soil geochemical anomaly and the coincident conductors. There were seven trenches excavated with the best mineralization discovered in trench #3 that assayed 8.4 per cent zinc, 3.5 per cent lead and 14.2 grams per tonne silver over a width of 17.2 metres (Assessment Report 29667). In 1992, Cominco Ltd. completed 16 diamond-drill holes totalling 1346 metres in the area of the trenching. The strike length explored is approximately 2.0 kilometres along a fault controlled, base metal mineralized structure on the east side of Wasi Creek. The work was not filed for assessment credit so there are no records of the results in the provincial database. In 1993, Cominco drilled four holes on the north side of the Osilinka River on a separate area and one hole in the Wasi Creek area in the vicinity of the 1992 drilling. In 1994, Cominco constructed more drill access roads and sites and completed four holes totalling 1164 metres, including two vertical holes drilled possibly to complete stratigraphic sections on either side of the fault controlled mineralization.

In 2000 and 2001, Cross Lake Minerals Ltd. acquired mineral claims over the property when the ground came open. The company carried out a program of geological mapping, stream sediment sampling and trenching. In 2002, anomalous stream sediment samples were followed up by soil geochemical sampling in areas upstream from the anomalies. In July 2002, Cross Lake Minerals Ltd. designed a soil sampling program to test both sides of an unnamed stream that was highly anomalous in base metal elements when sampled previously by the British Columbia Geological Survey. A total of 55 soil samples were collected and was successful in delineating two areas of anomalous base metal elements. Additional soil sampling programs were carried out on the property in two phases during the summer of 2004. The program was regional in scope and consisted mainly of a series of road traverses transecting the boundaries of the property. A total of 137 soil samples were collected from roadcuts at 100 metre intervals along roughly 13 kilometres of logging road.

In May 2005, Aeroquest Ltd. completed a helicopter-borne AeroTEM II electromagnetic and magnetometer survey over the Wasi Creek property for Cross Lake Minerals Ltd. The survey covered an area of 4 by 4 kilometres and a total of 186.8 line kilometres was flown. During June and July 2005, a seven-hole diamond drilling program totalling 1053.6 metres was completed targeting prospective EM conductors identified in the May 2005 airborne survey. No significant mineralization was detected in core from drillhole targets on the east side of Carrie Mountain and west of Wasi Creek. In June 2005, the Wasi Creek property was assigned to Selkirk Metals Holdings Corp. by Cross Lake Minerals Ltd. In August 2006, Selkirk Metals completed a trenching program at the Carrie prospect (094C 130) that comprised three trenches totalling approximately 203 metres. Additionally, two trenches totalling 60 metres were dug along the Par horizon but only encountered low grade mineralization. During November and December 2006, a program of NQ diamond drilling totalling 1094.0 metres in four holes was completed.

In 2012, a field program was designed by Selkirk Metals Corp. to test areas of the property that were either under explored or not explored all together; a total of 1382 soil samples were taken and analyzed. In 2018, Selkirk Metals Corp. carried out a geochemical sampling program and a total of 430 B-horizon soil samples (mobile metal ion (MMI) geochemical method) and 11 rock samples were taken and analyzed.
