Capsule Geology

The Ram occurrence is located on a north- to northwest-facing slope near Mount Pendelton, approximately 2.8 kilometres south of McDame Creek and 97 kilometres north of the community of Dease Lake.

Regionally, the area is underlain by a northwest-trending and southwest-dipping series of sediments comprising limestone, slate, siltstone and argillite of the Cambrian to Ordovician Kechika Group; quartzite and quartz arenite sedimentary rocks of the Silurian to Lower Devonian Ramhorn Group; limestone, marble and calcareous sedimentary rocks of the Middle to Upper Devonian McDame Group and mudstone and fine clastic sedimentary rocks of the Upper Devonian to Lower Mississippian Earn Group and Mississippian Slide Mountain Complex.

Locally, argillites, schists and tuffs of the Mississippian Slide Mountain Complex are folded into an anticlinal structure that plunges southeast. The main (P.H.S. 1) zone comprises an area of intense fracturing with tetrahedrite-bearing quartz veins. The quartz carries inclusions of schist and tuff and is locally laced with veinlets, patches and disseminations of tetrahedrite. Malachite and azurite were also observed. Two other zones of similar mineralization, referred to as the R (Lower) and S zones are location approximately 60 metres northwest and 360 metres southeast, respectively.

In 1900, 16 samples taken from a tunnel are reported to have yielded from 0.28 to 33.02 per cent copper and 181 to 5250 grams per tonne silver (Assessment Report 2593).

In 1969, two character samples (1091 and 1092) of mineralized material from the main (P.H.S. 1) zone assayed 1587.4 and 171.4 grams per tonne silver and 5.38 and 0.5 per cent copper, whereas a series of representative grab samples collected over a 7.5-metre long crushed zone located at the collar of hole F1, near the main zone, assayed 0.44 per cent copper and 68.8 grams per tonne silver (Assessment Report 2593). Also at this time, samples from the R (Lower) and S zones yielded 0.29 and 1.26 per cent copper with 459 and 591 grams per tonne silver, respectively, whereas a drillhole (F3) on the R zone intercepted a zone of quartz veining yielding 0.10 per cent copper and 84.4 grams per tonne silver over 1.5 metres (Assessment Report 2593).

Work History

The Ram Group of claims were originally staked in 1899 by B. O’Neil and a short tunnel was driven. The tunnel no longer exists.

In 1969, Fawn Bay Development Co. Ltd. conducted geological mapping, soil sampling, road construction and limited bulldozer trenching. In addition to this work, five exploratory drillholes were completed totalling 240.8 metres.

In 1991, the area was prospected by C. Berube and Douglas Busat as the CL claims. In 1997, International KRL Resources Corp. completed a 315.0 line-kilometre airborne magnetic and electromagnetic survey on the area.

In 2008, Pacific Bay Minerals Ltd. completed a 917.0 line-kilometre airborne magnetic and electromagnetic survey on the area immediately east of the occurrence as the Haskin-Reed property. The following year, a program of geochemical (rock, silt and soil) sampling and trenching was completed on the property.

Also during 2008 through 2010, Hawthorne Gold Corp., later China Minerals Mining Corp., completed regional programs of geological mapping and geochemical (rock and soil) sampling, and 11657 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.
