Property Geology

There are several showings on the Lucky Mike Property:

Lucky Mike-Skarn; Copper, Tungsten
The Lucky Mike is a polymetallic skarn mineralization is associated with altered sections of the marker horizon unit of the Upper Triassic Nicola Group. Limy volcanics, tuffs and limestone of this marker unit have been in part, converted to garnet-epidote- calcite skarn with associated copper, tungsten, silver and minor gold and zinc mineralization.  Recent drilling has indicated that tungsten mineralization is widespread in the garnet skarn while copper-zinc- gold-silver values tend to be restricted to late crosscutting structures.

The main skarn unit is 110 metres long with a northeast strike. It occurs at the contact between epidotized andesitic breccias and intermediate to felsic crystal-lithic tuffs within a lens of limy volcanic rocks, lithic tuffs and limestone (skarn protoliths). The skarn is bimodal in mineralogy, consisting of interfingering garnet skarn (andradite garnet, magnetite, epidote, hornblende, chlorite and calcite) and carbonate skarn (coarse calcite, epidote, hornblende, chlorite, minor magnetite or hematite) possibly reflecting original compositional variation (protolith-coarse, highly carbonated lithic tuffs(?)). Numerous late, fairly wide, east dipping (30-50 degrees) fracture zones cut the skarn with local displacements. A major fault zone is evident in the hangingwall lithic tuffs.

Diamond drilling has tested the skarn for 110 metres strike length and at a variety of elevations 40 to 80 metres below the old surface workings. Based on present and past drilling, indicated reserves of skarn available for tungsten mineralization is less than 90,710 tonnes (Assessment Report 18583).

Sunshine-Stockwork; Vein; Zinc, Lead, Copper

The Sunshine contains 3 zones (1-3);

The Tolman Lake area is underlain by intermediate volcaniclastic and flow rocks of the Upper Triassic Nicola Group which are intruded by Lower Jurassic granitic intrusives.  A strongly brecciated shear zone strikes 045o and  dips steeply to the northwest and is continuous over a strike length of 2.9 km.

Zone 1 (MINFILE # 92ISE129) is on the west side of Tolman Lake.  Open cuts expose a shear that strikes  085o and dips 065o to the north within andesitic tuffs.  The shear varies in width from 3-8 metres with steeply dipping quartz veins that coalese downward inyo a 30 to 60 metre vein. The vein is fractured and brecciated.  The fractures are mineralized with sphalerite and galena.

Zone 2 is located approximately 2.9 km northeast of Zone 1. The zone strikes for a minimum of 50 m. Brecciated andesite tuffs are mineralized with quartz, sphalerite, pyrite, chalcopyrite and galena. 

Zone 3 is located 2.3 km northeast of Zone 1. Galena, sphalerite, chalcopyrite, pyrite and pyrrhotite occur in a brecciated zone with a quartz-calcite matrix.  The hanging wall consists of bleached and pyritic andesite which grades into numerous calcite veins containing sphalerite and galena. The footwall consists of highly silicified andesite containing un-mineralized quartz and calcite veins.

Sophia-Stockwork;  Breccia; Zinc, Lead, Copper
The Sophia Lake area is underlain by interbedded volcanic and sedimentary rocks belonging to the Upper Triassic Nicola Group. The volcanic rocks consist of andesitic flows, porphyries, breccias and tuffs intercalated with limestone, argillite, greywacke and conglomerate. Bedding indicates a regional asymmetric anticline has its axis plunging south-southeast near Swakum Mountain. The Nicola Group rocks are bounded to the east and west by Lower Jurassic granitic intrusives.

A 175 metre wide limestone bed which a north trending ridge over 600 metres in strike length. The grey, coarse-grained limestone contains numerous fracture-controlled randomly oriented calcite stringers generally less than 2 millimetres in width. Local brecciated zones are calcite-healed and oxidized (hematite, limonite). In the central portion of the property a feldspar porphyry intrusive with euhedral pyrite up to 10 millimetres in size contains quartz eyes throughout the matrix.

At the Sophia showing, mineralization occurs in a shear zone exposed in a trench. The zone is 8 metres wide, strikes 220 degrees and dips 30 to 60 degrees south.  Calcite and quartz occur as narrow stringers in andesitic porphyry and as a cement in brecciated volcanics. Pyrite, sphalerite, galena and chalcopyrite are associated with the quartz and calcite.”
