The Tec Gold occurrence is situated on a logging road on the south side of Fortynine Creek, approximately 11 kilometres southwest of Nelson and immediately south of the past-producing Referendum (MINFILE 082FSW177) mine.
The area is underlain by basaltic volcanic rocks of the Lower Jurassic Elise Formation (Rossland Group) that have been intruded by dioritic rocks of the Early Jurassic Eagle Creek Plutonic Complex to the north and granitic to granodioritic rocks of the Middle Jurassic Bonnington Pluton to the south. Sedimentary rocks of the Triassic to Jurassic Ymir Group outcrop to the west.
Locally, a thin (up to 0.15 metre wide) discontinuous quartz-carbonate-chlorite vein contains visible gold, bornite, malachite staining and botryoidal turquoise mineralization (Hoy, 1987). The gold appears to be associated with bornite. The vein, a few metres in length, occurs parallel to the foliation in altered andesitic fragmental volcanics, strikes 125 degrees and dips 77 degrees south. On the same road farther to the west, a 5-metre wide band of chlorite schist hosts disseminated pyrite. Another similar zone of mineralization is exposed by an adit on the same road, approximately 1000 metres to the west, and consists of quartz vein in a sheared zone with chlorite-sericite schist.
In 1985, samples were reported have assayed up to 1.5 grams per tonne gold (Fieldwork 1985, page 333).
In 1986, a sample assayed 2.7 grams per tonne gold, whereas a 9.1-tonne shipment from the zone is reported to have averaged 1.7 grams per tonne gold (Property File - Snowater Resources Ltd. [1987-03-10]: Report on the Referendum Gold Prospect - 1987). Also at this time, a chip sample (no. 64680) from an exposure along the same road a few hundred metres to the northwest yielded up to 0.2 gram per tonne gold over 4 metres (Property File - I.M. Watson [1986-12-09]: Letter Re: Referendum Property Sampling/Drilling Programme 1986).
Intermittent production and exploration have taken place in the area since the late 1800s. Immediately north of the Tec Gold occurrence, operations began at the Referendum workings (MINFILE 082FSW177) in 1900. Minor gold production took place in the early 1900s and again in the mid-1980s.
To the east, the Gold Hill (MINFILE 082FSW092) occurrence has undergone intermittent production and development since 1890. Between 1890 and 1922, 115 tonnes of ore averaging 68.57 grams per tonne gold were extracted from the Gold Hill workings. The workings were re-examined in 1974 but then lay dormant until 1983. During 1983 through 1986, Golden Eye Resources conducted soil sampling, geophysical surveying and mapping and sampling of the underground workings. In 1986, Snow-Water Resources completed a program of geochemical sampling and three diamond drill holes, totalling 345.7 metres, on the area. No assays were reported from the drillholes. During 1988 through 1992, Formosa Resources Limited carried out extensive exploration work over the Gold Hill region, including the Tec Gold and Referendum claim areas.
In 2005, the Tec Gold claim was held by Acrex Ventures Limited as part of the Referendum property. Exploration consisted of rock and soil sampling and diamond drilling. The Tec Gold claim area was then acquired by Anglo Swiss. The claims were held as part of the Kenville property. In 2007 and 2008, Anglo Swiss Resources drilled 50 holes near the Kenville (MINFILE 082FSW086) mine. In 2009, on behalf of Anglo Swiss Resources, Equity Exploration Consultants Limited undertook an exploration program consisting of 680 line-kilometres of airborne electromagnetic geophysical surveying, surface diamond drilling, and underground rehabilitation and drilling. Ten diamond drill holes were completed on the south side of Eagle Creek, approximately 700 metres south of the Kenville mine.
By 2010, the Kenville property had been expanded to include separate claim groups to the north and south. In 2010, St. Pierre Geoconsulting Incorporated conducted airborne magnetic and electromagnetic geophysical surveys over the entire Nelson Mining Camp area on behalf of Anglo Swiss Resources. Soil sampling was conducted over the central Kenville claim block, though the majority of the sampling was conducted in the area of the Silver Lynx occurrence (MINFILE 082FSW378) to the southwest.
