The Nora (Davis vein) occurrence is located on the south side of small hill or knoll, approximately 450 metres southeast of the east end of McDame Lake and 92 kilometres north-northeast of the community of Dease Lake.

The area is underlain by grey-green aphanitic to sandy textured basalt flows and tuffs of the Upper Paleozoic Sylvester Allochthon (Slide Mountain Complex). Discontinuous rinds, possibly flattened or irregularly shaped pillows, occur north of the Davis vein. The volcanics, which locally exhibit a sub-brecciated or crackle texture, have been silicified and have undergone carbonate alteration.

The Davis vein follows a curved joint plane striking northeast and dipping steeply to the south. The vein has a width of 0.7 metre and a strike length of 200 metres. The vein consists of vuggy white quartz with native gold (in vugs near the vein/wallrock contacts) tetrahedrite and pyrite.

Production reported for the Norah claims in 1940 was 40.8 tonnes yielding 1371 grams of gold (Index 3, page 207).

In 1975, diamond drilling by New Coast Silver (drillhole 75-7) reported an assay of 34.97 grams per tonne gold across 0.6 metre, but assay values are generally erratic (Assessment Report 5704).

In 1981, drillhole MBC 81-2, located on the Davis vein area, intercepted a 4-centimetre wide tetrahedrite-bearing quartz vein which yielded 13.1 grams per tonne gold over 1.0 metre (Assessment Report 10249).

In 2008, a chip sample (5000014) assayed 4.14 grams per tonne gold over 1.0 metre (Assessment Report 30623).

Work History

In 1975, New Coast Silver completed seven diamond drill holes, totalling 458.0 metres, on the Nora claims. In 1977, Nu-Energy Development Corp. completed five diamond drill holes, totalling 324.0 metres, and a 29.0 line-kilometre ground electromagnetic (VLF) survey was completed on the BB, Up, Top 1-5, Nora, FG 1, Mill, Val, Ned and Jennie Ext. claims.

During 1979 through 1982, Esso Resources Canada Ltd. completed programs of geological mapping, geochemical (rock, silt and soil) sampling, 1261.3 metres of diamond drilling, trenching and ground electromagnetic (VLF) surveys on the area as the McDame property.

In 1986, Erickson Gold Mines completed a trenching and soil sampling program on the area immediately east as the Go claim.

More recent exploration programs, during the 1990s, 2000s and 2010s, were completed by Cusac Gold Mines Ltd., Hawthorne Gold Corp. and later China Minerals Mining Corporation, and a complete exploration history can be found in the Table Mountain (MINFILE 104P 070) and Taurus (MINFILE 104P 012) occurrences.

In 2020, Cassiar Gold Corp. completed a program of regional photogeological interpretation, prospecting and rock sampling on the Cassiar Gold property.
