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 Vista 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, calcsilicate schist and gneiss, with intercalated layers of marble. Pegmatite and associated medium-grained granitic rocks replace and intrude the metasediments.

The Vista A showing is a partially exposed band of very dark brown fine to medium grained massive sphalerite with subordinate galena, pyrrhotite, chalcopyrite and pyrite(?). The band was exposed by blasting to establish a road surface for the Cornice Logging road at about kilometre 9.3. The band is at the contact of sulphidic siliceous gneisses in the structural footwall and an overlying 2 (plus) metre thick band of calcsilicate rocks that appear to be highly metamorphosed limestones. The showing appears to be part of a moderately (10-20 degrees) southeast plunging partially eroded antiform or northeast dipping monocline. Rocks to the northeast change dip to moderate to steep northeast dips. Exposures to the southwest are eroded off, and covered by glacial debris, or have not been mapped.

The observed mineralization is in the form of planar to swirled bands of nearly massive sulphides up to 35 centimetre thick that grade up into bands of semi-massive sulphides in a calcsilicate host. The contact with the underlying silicate rock appears very sharp. The band of Vista A type mineralization is exposed discontinuously over about 20 metres; it is assumed to be continuous although it is truncated at surface to the northwest by a northwest-striking, moderately northeast dipping fault that brings a pegmatite dyke into direct contact with the mineralization. To the southeast it plunges below the logging road. Selected grab samples from bedrock exposures assayed up to 24 per cent zinc, 4.9 per cent lead and 72 grams per tonne silver (Lindinger, personal communication, Jan.2001).

Vista B type mineralization occurs 2 to 3 meters structurally above the Vista A horizon in calcsilicate rocks. This zone also appears to be stratiform, exposed as a 5 to 10-centimetre thick band of dark brown, coarse grained massive to semi-massive sphalerite. No lead, silver or copper is reported. The band is exposed in its unweathered form for at least 5 meters, about 20 meters southeast of the Vista A discovery outcrop. To the northwest it is eroded off. To the southeast it also plunges below the road. To the northeast, if continuous it would dip to the northeast as part of the stratigraphic package.

Vista C type mineralization (discovered by Warner Gruenwald, P.Geo.) are fault-hosted(?) 4 to 6 centimetre thick silvery-grey, medium to fine grained massive to semi-massive sphalerite and galena bands that appear to both occupy the top of and crosscut the calcsilicate horizon hosting the Vista A and B mineralization. Weathered exposures are visible over an 8 by 2.5 metre exposure of the top of the calcsilicate horizon above the fresh exposures of the Vista B mineral band. A sample (0.8 metres long by 8 centimetres thick) taken by Gruenwald yielded 6.6 per cent zinc, 4.1 per cent lead and 6.2 grams per tonne silver (Lindinger, personal communication, Jan.2001).

The calc-silicate unit hosting various types of zinc-rich sulphide mineralization appears to contain erratically distributed, weakly disseminated sphalerite and possibly galena. Traces of other iron- and copper-bearing sulphides are also present. Uncertainty about the showing is due to the generally well-weathered nature of the surface exposures and lack of sample assay data.

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 and Navan (MINFILE 082M 279) showings. The highlights at the Vista showing were drillhole BH01-03, which returned 0.4 metres grading 4.76 per cent zinc, and drillhole BH01-13, which returned 3.9 metres grading 2.52 per cent zinc (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. Highlights from the drill program include drillhole BH05-15, which returned 0.33 metres grading 10.20 per cent zinc, 1.15 per cent lead and 9.6 grams per tonne silver (Assessment Report 28047).

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. Highlights from this program include drillhole BH08-19, which returned 0.1 metres grading 15.8 per cent zinc (Assessment Report 30610). 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.
