The Prince George map area contains 59 recorded mineral occurrences.
The Prince George map area contains 59 recorded mineral occurrences. The
area is located in the Intermontane and Omineca belts primarily comprising parts of the
Quesnellia and Cache Creek terranes but also including parts of the Barkerville, Slide
Mountain and Stikinia terranes. The region is underlain by rocks of the Upper
Mississippian Slide Mountain Group, the Mississippian to Triassic Cache Creek Group, and
the Jurassic to Triassic Nicola and/or Takla groups, intruded by the Cretaceous Naver
Intrusive suite and the Jurassic Mouse Mountain stock.Massive sulphides
occur at the G-South
(093G 007) prospect, hosted in Takla Group volcanic rocks. The Mouse
Mountain (093G 003) porphyry copper deposit, hosted in Nicola Group volcanics
and the Mouse Mountain stock, produced copper, silver and gold in 1956. The Pioneer
(093G 013) deposit, consisting of argentiferous galena and sphalerite in a quartz vein
within Takla Group shale, produced minor amounts of silver, lead of zinc in 1927. Similar
quartz veins have been noted throughout the area. The Quesnel
Quartz (093G 015) deposit, which consists of mineralized quartz veins within
a shear zone within Takla Group rocks, produced 6438 grams of gold and 8553 grams of
silver up to 1939. Minor tungsten, molybdenum, copper and bismuth occur in veinlets within
Nicola or Takla Group metasedimentary rocks and molybdenum has also been noted in
granodiorite of the Naver Intrusive suite. Placer gold occurs along the Fraser and Cottonwood
(093G 025) rivers.
Up to 1987, 532,821 tonnes of limestone were quarried from the Dahl
Lake (093G 032) quarry and a few tonnes were produced from the Beverly
(093G 042) deposit early this century. Minor quantities of clay have been produced from a
pit located near Prince George.
