The T.G.S. occurrence is located 1.2 kilometres north-northwest of the confluence of Forty-five Mile and Whipsaw creeks, 26 kilometres southwest of Princeton. The BZ prospect (MINFILE 092HSE207) is 550 metres to the south.
The region at the headwaters of Whipsaw Creek is underlain to the west by intrusive and metamorphic rocks of the Late Jurassic to Early Cretaceous Eagle Plutonic Complex and to the east by metamorphosed volcanics and sediments of the Upper Triassic Nicola Group. The contact between the two units trends north-northwest.
A zone of brecciation and mineralization occurs between two closely-spaced fault planes, striking north, in gneiss and schist of the Nicola Group. This deposit is one of several occurrences (Metestoffer, MINFILE 092HSE097; BZ, MINFILE 092HSE207) hosted in the same fault zone, which strikes north for at least 1.4 kilometres.
The breccia is mineralized with pyrite, sphalerite and chalcopyrite. Pyrite and chalcopyrite occur in the quartz matrix, while most of the sphalerite is in breccia fragments. One sample studied by thin section is estimated to contain 13 per cent pyrite, 6 per cent sphalerite and 0.5 per cent chalcopyrite (Assessment Report 2802, Appendix 2). The breccia fragments are silicified and sericitized. A chip sample taken across an adjacent feldspar porphyry dike assayed 0.19 per cent copper over 6.7 metres (Property File - D.K. Mustard, 1969, page 28, trench 1).
In 1991, a diamond drill hole (91-5) intercepted 0.09 per cent copper over 146 metres; including 16.4 metres yielding 0.162 per cent copper (Assessment Report 21186). Another drill hole (91-10), located approximately 400 metres to the north, yielded 0.102 per cent copper over 151.8 metres; including 0.162 per cent copper over 48.0 metres (Assessment Report 22147).
The area has been explored in conjunction with the nearby Whipsaw (MINFILE 092HSE102) and S&M (MINFILE 092HSE073) occurrences since the late 1950’s. Various operators, including Texas Gulf Sulfur Company Ltd. conducted geophysical, geological and soil surveys and trenching between 1959 and 1981. The area was more recently explored by World Wide Minerals Ltd., with the completion of geological mapping and soil surveys between 1987 and 1993. In 1991, Phelps Dodge Corporation of Canada Ltd. completed 22 drill holes, totalling 2066 metres. During 1995 through 1998, Martech Industries completed 10 diamond drill holes, totalling 1033.5 metres, on various targets over the Whipsaw property. In 2000, a pulp sampling program was completed to test for platinum group elements from former trenching and drilling programs but results were disappointing. In 2005, Canfleur Mining completed a program of sampling and seven diamond drill holes, totalling 1452.8 metres, on the area. During 2010 through 2015, Martech Industries completed programs of rock and soil sampling.
