The Weaver property covers several significant showings of gold-quartz veins and shears located in the Weaver Creek drainage in the upper reaches of the Moyie River, a known placer gold area (82FSE102) where placer mining was carried on recently by Queenstake Resources. Other known gold mineralization in the area includes David (82FSE108, 6 kilometres southwest) and Perry Creek drainage, 10 kilometres to the northwest.
The claims are underlain by sedimentary rocks of the Aldridge and Creston formations of the Middle Proterozoic Purcell Supergroup. Lithologies include turbidite siltstone, quartzite, argillite and Moyie gabbro intrusions; there are rare felsic dikes of possible Cretaceous-early Tertiary age, likely associated with mineralization.
Gold-quartz veins of possible mesothermal to epithermal character occur in at least three locations on the property, and are called the Hill vein, the MC2 shear, and the Galena vein. The Hill vein is a north striking, shallow west-dipping quartz vein exposed by trenching along a strike length of more than 500 metres. Grab samples of the vein material, which contains visible gold, pyrite and limonite, yielded assays up to 31.8 grams per tonne gold (Assessment Report 20013). The vein is between 0.5 and 1 metre thick. Felsic dikes associated with the vein contain disseminated pyrite, specular hematite and chloritic fractures, as well as thin lens quartz veinlets; Middle Aldridge sediments adjacent to the dikes are altered and stained by manganese and limonite. A possible extension to the vein is 0.5 metre thick and bedding- parallel; altered quartzites on both sides of the vein are brecciated with quartz veining, limonite and minor pyrite, and assay up to 340 parts per billion gold.
The MC2 shear is a northeast-trending structure in the upper Weaver Creek area that contains gold values up to 2800 parts per billion; galena is rarely observed in quartz veinlets in this structure.
At the Galena vein, gold values up to 4800 parts per billion over 40 centimetres were found in the sheared margins of a diorite dike that probably is part of the Moyie intrusions of Middle Proterozoic age. Gold and minor galena occurs in quartz veins up to 1.2 metres thick and silicified Middle Aldridge siltstones and argillites at the margins of the diorite dike.
In 1995-1996, Excel Geophysics Inc. performed a series of geophysical surveys on the Weaver claims. In 1997, the claims were restaked as the Shadow claims and a program of regional prospecting was performed.
