The Mill-Caleb occurrence is located at an elevation of approximately 980 metres on a gentle northwest slope, south of McDame Lake and approximately 1.1 kilometres east of the north end of Callison Lake.

The area is underlain by basaltic volcanic rocks of the Mississippian Slide Mountain Complex.

Locally, carbonate-altered volcanics host quartz veins with minor pyrite, tetrahedrite, chalcopyrite and trace sphalerite.

In 1985, drilling yielded intercepts of 3.8 and 10.3 grams per tonne gold over 1.0 and 0.9 metre in holes 85-587 and 85-586, respectively, whereas a sample from a 0.5-metre quartz vein, striking 025 degrees and dipping 75 degrees to the northwest, and located approximately 150 metres north-northeast of the drillholes, yielded 2.1 grams per tonne gold (Assessment Report 14418).

Work History

The area has been explored in conjunction with the nearby Gold Hill-Lakeshore (MINFILE 104P 017) occurrence and a complete exploration history can be found there.

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, 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 1985, Erickson Gold Mining completed five diamond drill holes, totalling 345.3 metres, on the area. Previous to this the area had been prospected, geologically mapped, trenched and sampled.

In 1995, the area was held and examined by Cusac Gold Mines Ltd. as the Table Mountain Gold property.

During 2008 through 2010, Hawthorne Gold Corp., later China Minerals Mining Corp., completed regional programs of geological mapping, geochemical (rock and soil) sampling and 11,657 line-kilometres of airborne magnetic, radiometric and electromagnetic surveys on the area as the Cassiar Gold property.

In 2019, Margaux Resources completed a program of prospecting, geological mapping and rock sampling on the area as the Cassiar Gold property. In 2020, Cassiar Gold Corp. completed a program of regional photogeological interpretation, prospecting and rock sampling on the Cassiar Gold property.
