The Easy Number 1 showing is situated 1.7 kilometres due west of the village of Skookumchuck and 29 kilometres northwest of the north end of Harrison Lake.

Mineralization on and near the Easy Number 1 prospect have been known since about 1897 when the Mayflower claims (092GNE010) were staked. In 1982, the area surrounding the Mayflower claims were staked by Hillside Energy Corp. as the Easy #1 and #2 claims. Anomalous silver and gold were discovered. A silver anomaly near the south-central part of the Easy Number 1 was tested with 4 drillholes by Hillside Energy Corp., Lacana Mining Corp. and Symes Resources. A strong gold and base metal soil anomaly was delineated by in the southeastern part of the Easy Number 1 claim. Symes Resources transferred its option to Kali Venture Corp. in 1989. Hillside Energy Corp. was also consolidated into Charter Minerals Inc. Lacana later amalgamated to form Corona Corp. In 1989, 5 drillholes, totalling 405.4 metres, were drilled on the Easy Number 1 claim by Kali Venture Corp. for owners Charter Minerals Inc. and Corona Corp.

Regionally, the prospect lies within a Mesozoic volcano- sedimentary sequence along the southeast flank of the Jurassic to Cretaceous Coast Plutonic Complex. The predominant lithological unit surrounding the Easy Number 1 prospect is the Lower Cretaceous Fire Lake Group. These rocks form a roof pendant northwest of Harrison Lake composed of three distinct stratigraphic units. The basal section consists of granulite, andesite, conglomerate, limestone and quartzite. The central unit consists of dark slates, shales, argillite and greywacke. The upper unit consists of clastic feldspathic greenstone, chlorite schist and minor conglomerate. The major structural features in the vicinity are the Harrison Lake shear zone and a set of younger northeast trending brittle faults.

A quartz vein stockwork is developed over a 500 by 500 metre area within the fourth (uppermost) member of the Lower Cretaceous Brokenback Hill Formation, Fire Lake Group. The stockwork is hosted in andesitic lapilli tuff (greenstone), argillite (mudstone), quartz feldspar porphyry and interbedded chlorite schist and quartz sericite schist. The quartz feldspar porphyry occurs as several small, elliptical bodies, up to 300 metres in length, intruding all other lithologies.

Mineralization consists of stringers and disseminations of pyrite with minor pyrrhotite, chalcopyrite and galena and traces of sphalerite associated with the quartz vein stockwork.

Silver values of up to 161 grams per tonne over widths of up to 0.5 metre are reported from surface exposures (Assessment Report 16789, page 4). A drillhole (Hole 84-2) intersected a 8.23-metre section grading 23.3 grams per tonne silver, 0.4 per cent lead and zinc values up to 2.5 per cent over 1.2 metres (Property File - Jenkins, D.M. (1987)).

In 1989, diamond drilling which tested a gold and base metal anomaly, yielded a significant intersection. The anomaly, discovered in 1988, trends northwest approximately along a contact between recessive dacite and/or dacitic lapilli tuff and latite/andesite tuff. Drillhole 89-1 yielded a maximum of 4.23 grams per tonne gold (sample 30950) over 46 centimetres between 4.42 and 4.88 metres depth and 5.39 grams per tonne gold (sample 14783) over 46 centimetres between 18.29 and 18.75 metres depth (Assessment Report 20305). Drillhole 89-3 yielded a maximum of 3.90 grams per tonne gold (sample 14825) over 91 centimetres between 7.31 and 8.22 metres (Assessment Report 20305).

Near the site of this anomaly, bulldozer trenching has exposed a 3-metre-wide zone of intense shearing and limonitic alteration over a width of 3 metres. The zone strikes about 320 degrees and dips 70 to 75 degrees to the east, approximately parallel to the regional foliation. The zone is also weakly silicified and contains manganese oxide staining. Pyrite, galena, sphalerite and native gold have been identified. A grab sample from this zone yielded 13.61 grams per tonne gold (Assessment Report 20305). The gold appears to be related to a late stage, fault controlled mineralizing event.
