The Broken Hill prospects, located near Avola, BC, were discovered by geologist J.E. Leo Lindinger on September 6, 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. 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 Navan showings of the Broken Hill property lie 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 Navan A showing is a poorly exposed, partially weathered band of dark brown, fine-grained massive sulphides (sphalerite and galena) hosted by disrupted (frost heaved?) calc-silicates and impure quartzites, probably correlative with the cover sequence of the dome. The grade and style of mineralization is very similar to the Vista A showing (082M 280); however, the highest grade exposures of Navan A are totally within calcsilicate host rocks. Massive sulphide mineralization up to 25 centimetres across and grading up to 23 per cent zinc, 4.05 per cent lead and 17 grams per tonne silver occurs as boulders that were dug out of subcrop exposures. Exposed hanging-wall rocks include thin, impure quartzite layers with minor disseminated pyrrhotite. The host succession appears to trend northward and dip at moderate angles to the east.
The Navan B showing is about 130 metres north of the Navan A exposure. Here, a 1.5-metre long and 5 to 10-centimetre thick band of massive sphalerite occurs in west-dipping, quartz-rich, schistose rocks. No real bedrock exposures can be seen and the rock hosting the sulphides may be a large, rotated subcrop boulder. A 0.3-metre thick sample which included the massive sulphide mineralization yielded 5.6 per cent zinc, 0.6 per cent lead and 8.4 grams per tonne silver.
An open-ended soil anomaly immediately north (up ice) and west (downhill) of the Navan B showing contains the highest zinc (2590 parts per million) and lead (412 parts per million) values found to date (600+ samples).
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 showings. The highlight at the Navan showing was drillhole BHDDH01-06, which returned 0.25 metres grading 1.19 per cent zinc and 0.12 per cent lead (Assessment Report 26692). 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.
