Limestone of the Triassic Slocan Group outcrops on Lot 11329, 3 kilometres south of Pingston Creek, on the west side of Upper Arrow Lake. The bed continues northwest for 400 metres where it is truncated by a monzonite stock of the Jurassic Kuskanax batholith.

The deposit is comprised of fine to medium grained, white to bluish grey, banded limestone containing a considerable amount of pyrite along partings. Some pink banding is also evident.

The area was staked in 1914 by Mrs. Howieson
