Summary:
The Boulder Mountain Property is located in the Similkameen region of South Western British Columbia. The Boulder Mountain is underlain by andesitic to locally dacitic flows and pyroclastic of the upper Triassic Nicola group. These rocks are uncomformably overlain by felsic to intermediate volcanics of the middle to upper cretaceous Spence’s bridge group. These volcanic rocks are highly prospective for epithermal style gold mineralization.
Location:
The Boulder Mountain mineral claims are located 7.5km’s north northwest of Tulameen B.C. in the Similkameen mining division. It is significant that the claim block lies within the mountain pine beetle area and has recently been logged. This has greatly improved access to all areas of the property which has previously had poor access.
Mineralization:
The horizon consists of a zone of pyritized, chloritized, silicified, bleached and sheared andesite (greenstone), containing 2 to 20-centimetre wide strata bound to crosscutting chalcopyrite- pyrite rich bands and quartz-carbonate-chalcopyrite-pyrite veins. The zone is 1.0 to 3.0 metres thick, and averages 1.5 metres in thickness. A halo of hematite and epidote alteration surrounds this pyritic horizon. Multiple showings across the property—including the South Copper, Mid Copper, North Copper, and James X zones—feature chalcopyrite-bearing veins, stockworks, and stratiform sulphide zones with grades up to 2.94% Cu and 88 g/t Ag in surface samples, and drill intercepts of up to 1.29% Cu over 2.1 metres. The boulder mountain property consists of multiple high grade mineral showings as well as silver zinc occurrences.
Work Completed:
This copper deposit was first explored in 1901. The prospect remained largely undeveloped until Gold River Mines Ltd. conducted trenching and drilled 9 holes totalling 894 metres during 1972 and 1973. Since then, the deposit has been trenched, mapped and sampled by various operators between 1980 and 2025.
Potential:
The Boulder Mountain property exhibits strong potential for hosting a porphyry copper system, supported by widespread copper-silver mineralization, extensive alteration, and a favorable geological setting within Upper Triassic Nicola Group volcanics. These zones are associated with strong structural controls, pervasive silicification, chlorite-epidote alteration, and localized quartz stockwork veining—hallmarks of a porphyry environment. Although most mineralized zones identified to date are relatively narrow, their distribution, alteration intensity, and metal content suggest they may represent the upper levels or flanks of a concealed porphyry system at depth. With limited historical drilling and no modern geophysical surveys, the Boulder Mountain property offers a compelling opportunity for discovery-focused exploration targeting bulk-tonnage porphyry copper mineralization.
