The St. Keverne occurrence is situated on the upper northeast slope of a high ridge northwest of Mount Payne, between McGuigan and Carpenter creeks. New Denver, BC, lies 10 kilometres to the southwest. The claims covering the St. Keverne occurrence lie 1 kilometre northeast of the Payne occurrence (MINFILE 082KSW006).

The St. Keverne occurrence is hosted by limy argillite, quartzite, slate and limestone of the Triassic Slocan Group, intruded by various dikes and sills of quartz feldspar porphyry. The structure of the upper part of the nearby Payne mine is a recumbent fold open to the northeast. The fold has a near-horizontal axial plane and plunges a few degrees to the southeast. A second recumbent fold, open to the northeast, is believed to occur below the No. 15 level. Ore shoots lie within the zone of maximum curvature of these folds. For a more detailed description of the geology, refer to the Payne occurrence (MINFILE 082KSW006).

Information regarding the mode of occurrence and mineralogy at the St. Keverne occurrence are scant. Galena is reported (Minister of Mines Annual Report 1899, page 688). Sphalerite, galena, tetrahedrite and pyrite hosted in quartz are reported in samples taken from stockpiled ore at the portal to the former St. Keverne mine (Assessment Report 15472). It has been classified as a vein-type deposit (Geological Survey of Canada Open File 464). Several of the samples taken from the ore stockpile contained significant zinc and silver values. Sample 8611-3 yielded 225 grams per tonne silver, 49.8 per cent zinc, 1.4 per cent lead and 0.45 per cent copper (Assessment Report 15472).

The St. Keverne group of claims were first staked in 1894, with lessees beginning work on the property in the following year. The St. Keverne occurrence was operated by the St. Keverne Mining Company Limited in 1897. The property was transferred to a new St. Keverne Mining Company Limited in 1901. Known production for the St. Keverne consisted of small shipments in 1902 (6.35 tonnes) and 1905 (8.16 tonnes). Approximately 140 metres of tunnel and a 13-metre raise and winze were driven before operations closed in 1901. The property was then purchased in 1907 by Payne Mines Limited, owners of the neighbouring Payne occurrence. A new portal was collared below the old portal in 1951 under the direction of Kootenay Belle Gold Mines Limited. Production totalled 14 tonnes of ore with recovery of 71 538 grams silver and 11 384 kilograms lead (NMI 082K3 Ag8), grading 5015 grams per tonne silver and 78 per cent lead, respectively (Geological Survey of Canada Memoir 184, page 141).

In 1986, exploration was conducted by Boa Services Ltd. for Kobold Resources Ltd. on the old St. Keverne property, then referred to as the Merit South property. The program included soil and rock geochemistry sampling and electromagnetic-magnetic ground surveys

In 1992, Minotaur Explorations Limited conducted a 59-sample soil geochemistry survey on the Smoke and Trak claims to the northwest.

In 2008, Klondike Silver Corporation owned the claims covering the St. Keverne occurrence as part of their Payne property. That year, 1179 soil samples were collected from a 360-hectare sample grid to the immediate west of the St. Keverne showing. The following year, Klondike Silver Corporation completed a program of geological mapping, geophysical surveying and trenching over a smaller portion of the Payne property. In total, four trenches and 8.95 line kilometres of very low-frequency electromagnetic geophysical surveying were completed over a 4.12-hectare area to the west of the St. Keverne occurrence.

In 1987, samples 8611-3 and 8611-4, taken from the St. Keverne dump, returned 49.8 per cent zinc and 225 grams per tonne silver and 25.4 per cent zinc and 375 grams per tonne silver, respectively (Assessment Report 15472).
