The Pingston occurrence is located on a small knoll north of Kiln Creek, approximately 1.5 kilometres west of Upper Arrow Lake.

The area is located near the eastern margin of the Precambrian-Paleozoic Shuswap Metamorphic Complex in the south eastern portion of the Thor-Odin gneiss dome. Metamorphism is generally amphibolite to granulite grade, locally reaching the sillimanite facies. These have been intruded by Late Paleocene to Early Eocene granitic rocks to the south.

The showings are hosted in a 1.0 to 1.5- metre thick conformable bed of massive pyrrhotite-pyrite containing up to 30 per cent sphalerite and minor chalcopyrite and galena. The horizon has been traced for 240 metres and strikes east, dipping 40 degrees south. The sulphide-rich strata have been isoclinally folded and overturned to the south. The sulphide layer is hosted within the "Ledge Member", which is composed of biotite phyllite, quartz biotite schist with variable amounts of muscovite and graphite and quartz feldspar biotite schists. The "Ledge Member" contains up to 10 per cent disseminated sulphides (pyrite, pyrrhotite and sphalerite) and is commonly cut by stringers of quartz feldspar pegmatite.

In 1979, sampling from a pit near the former adit yielded up to 4.19 per cent zinc, 0.18 per cent lead and 5.1 grams per tonne silver, while sampling to the south west yielded up to 5.3 per cent zinc, 0.16 per cent lead and 6.8 grams per tonne silver (Assessment Report 08415).

In 1988, a grab sample (42598) assayed 6.4 per cent zinc, while another grab sample (42599) yielded 1.33 per cent zinc, 0.238 per cent lead and 4.7 grams per tonne silver (Assessment Report 17979).

In 1992, trench sampling yielded up to 4.5 per cent zinc, 0.45 per cent lead and 4.9 grams per tonne silver from Trench 9 and 1.74 per cent zinc, 0.15 per cent lead and 4.8 grams per tonne silver from Trench 11 (Assessment Report 22664).

An adit of unknown age and length is reported at the occurrence. The area was staked and explored by Cominco during 1947 through 1966 as part of the Big Ledge (MINFILE 082LSE012) property. In 1977, the area was reconnaissance mapped by Metallgesellschaft. During 1979 through 1981, Esperanza Explorations Limited completed programs of geochemical sampling, geophysical surveys and geological mapping. In 1988 and 1989, Noranda Exploration Company completed programs of soil and rock sampling, line-cutting and geological mapping on the area as the Ping Pong claims. In 1992, Teck completed a program of soil and rock sampling, geological mapping, trenching and a magnetometer survey on the area as the Arrow claims. During 2006 through 2010, Zinex Mining completed programs of prospecting, rock sampling and a ground magnetic survey on the area.
