Capsule Geology

The Golden Cache occurrence is situated southeast of Spider Peak, approximately 1 kilometre north of the Carolin mine (MINFILE 092HNW007).

The area is underlain by grey to black, locally organic-rich, pyritic slaty argillite intercalated with well-bedded siltstone and minor bands of wacke, all assigned to the Early and Middle Jurassic Ladner Group.

The occurrence comprises six parallel quartz veins, striking 110 degrees and dipping steeply to the north and south, similar to those developed at the Gem occurrence (MINFILE 092HNW010) to the north. The veins are hosted by slate and are sparingly mineralized with pyrite and arsenopyrite. Gold values in the veins were generally low, although systematic testing had not been carried out (Geological Survey of Canada Memoir 139, page 145).

In 1973, Carolin Mines completed a program of soil sampling, a 37.0 line-kilometre ground magnetic survey and trenching on the area. In 2012, New Carolin Gold completed airborne magnetic and radiometric surveys, totalling 759 line-kilometres, on the area. The area has been historically explored in conjunction with the nearby Ladner Creek (MINFILE 092HNW007) mine and, more recently, the McMaster (MINFILE 092HNW018) occurrence.
