The Broken Hill prospects, located near Avola, BC, were discovered by geologist J.E. Leo Lindinger in late 2000 while working on a grassroots exploration project funded in part through the Ministry of Energy and Mines Prospectors Assistance Grant Program. In October 2000, Cassidy Gold Corporation entered into an agreement with Lindinger to acquire the 1800-hectare property, which includes the Mike showing. The following deposit description is taken in large part from a report by Lindinger, provided to the Ministry of Energy and Mines in January 2001. Some additional information was also provided by BC Geological Survey geologist T. Hoy, who visited the showings after their discovery in 2000.
The Mike showing of the Broken Hill property occurs northwest of Frenchman Cap Dome within the Proterozoic Shuswap Metamorphic Complex. Paleoproterozoic (Aphebian) core gneisses of the dome are overlain by a cover sequence of metasedimentary rocks consisting of micaceous schist, calc-silicate schist and gneiss, with intercalated layers of marble. Pegmatite and associated medium-grained granitic rocks replace and intrude the metasediments.
The Mike float showing contains cobbles and boulders of dark brown massive, semi massive and disseminated fine to coarse-grained sphalerite and pyrrhotite associated with garnetiferous calc-silicate, pyrrhotitic silicate and coarse-grained pegmatitic rocks. These are exposed over 40 metres in a series of pits dug for material to upgrade the Shannon Creek logging road. The cobbles and boulders can be dug out of the bank and occur within discrete stratigraphic zones near to and overlying possibly disrupted pegmatitic bedrock. Northwest of the float occurrence is an area of calc-silicate float and bedrock extending for over 2 kilometres. To the southeast, deep glacial till extends to Shannon Lake.
One sample of a massive sphalerite boulder yielded 19.6 per cent zinc and 352 parts per million cadmium (Gruenwald, Personal Communication, 2000). This and other samples have consistently lower lead values than the Navan (082M 279) and Vista (082M 280) prospects of the Broken Hill property.
In 2000, Cassidy Gold Corp. optioned the Broken Hill property and conducted geological mapping, a gravity survey and soil and rock sampling.
In 2001, Cassidy Gold Corp. completed a 13-hole, 930-metre diamond drill program targeting the Vista (MINFILE 082M 280) and Navan (MINFILE 082M 279) showings. Cassidy Gold Corp. terminated their option in late 2001.
In 2002, Cross Gold Corp. optioned the Broken Hill property.
In 2003, B2B Solutions Inc. acquired the option from Cross Gold Corp. and conducted an exploration program of soil and rock sampling and geological mapping.
In 2004, B2B Solutions Inc. changed their name to Timer Exploration Inc. and completed soil, moss mat and rock sampling on the property.
In 2005, Timer Exploration Inc. completed an exploration program of geochemical sampling, prospecting, trenching and diamond drilling.
In 2006, Timer Exploration Inc. conducted soil sampling, ground magnetometer surveys and trenching around the Broken Hill property.
In 2008, Timer Exploration Inc. changed their name to Potash North Resources Corp. and completed a 7-hole drill program. Inlet Resources Ltd. acquired 50 per cent ownership of the property by funding the 2008 program.
In 2009, Potash North Resource Corp. sold their 50 per cent ownership of the property to Kevin Russel of Monster Uranium Corp.
In 2011, Inlet Resources Ltd. completed a gravity survey and a single diamond drillhole. The drillhole intersected 4 narrow mineralization horizons, the best assaying 5.98 per cent zinc, 1.21 per cent lead and 16 grams per tonne silver over 0.25 metres (Assessment Report 32834).
