The WAL occurrence is located 1 kilometre south of Brassy Gulch, 1.5 kilometres southwest of the community of Walhachin.
The area is primarily underlain by hydrothermally altered andesite flows and fragmental volcanic rocks of the Upper Triassic Nicola Group containing moderate to high concentrations of fine-grained, disseminated magnetite and variable amounts of pyrite. Several large limestone/marble bodies occur within the Nicola volcanics, commonly in fault contact. They strike north to northwest and are steeply dipping. A large body of hornblende diorite intrudes the Nicola Group. A smaller body of quartz porphyry intrudes both the Nicola rocks and the diorite.
In 1979, percussion drilling was completed on the Wal property to assess the mineral potential around the periphery of a gossan and to attempt to intersect a nearby mineralized intrusive breccia (Chief [MINFILE 092INW055] occurrence) that crops out on the west bank of a creek near the south part of the Wal claim. Hole W-79-1, the northernmost hole, was drilled in the bed of a creek north of the first gossan outcrop. It intersected dark-green Nicola volcanics and felsic intrusive quartz porphyry. Both units show strong pyrite mineralization with traces of chalcopyrite and malachite. Copper contents vary from 0.004 to 0.192 per cent with higher grades near the intrusive contact (Assessment Report 7736).
Work History
In 1978, Bethlehem Copper Corporation performed geological mapping, an electromagnetic survey over 5.6 kilometres and a geochemical survey. The following year, a six-hole, 597-metre percussion drilling program was carried out.
In 1999, Christopher James Gold Corp. completed a drilling and rock sampling program on the Brassie Creek property. Three drillholes, totalling 324.6 metres, were completed and 141 core samples were submitted for assay. A total of 82 rock samples were collected and submitted for assay.
In 2015, K. Ellerbeck collected 12 grab samples as part of a prospecting program on the Brassie claim group; three grab samples were assayed. In 2019 K. Ellerbeck collected 13 grab samples, four of which were submitted for assay.
