Silver Lake nickel mine was developed on the Lunnon Shoot, named after diamond driller Jack Lunnon who drilled the discovery hole, KD1, in 1966. The mine was operated by WMC continuously from 1966 until its closure in the 1985/86 financial year, producing 4.54 million tonnes of ore at 2.72% Ni for over 123,000 tonnes of nickel metal based on WMC’s production records. The Silver Lake mine and the nickel shoots it hosts are developed on the southeast flank of the Kambalda Dome, with the historical workings plunging for approximately 2.5km to the south-southeast and extending over a vertical distance of at least 350m (from lake surface to 50m below sea level).

Silver Lake Hanging Wall - Exploration Target
An Exploration Target for SLHW has been estimated by the Company in accordance with the guidelines of the JORC Code (2012). The work focussed on the extensive hanging wall surface known during the operational life of the mine as the ‘25H’. The combined tonnage and grade potential of the Exploration Target is estimated to be in the range of approximately 650,000t to 1,300,000t with an average grade of between 1.3% to 2.7% nickel. The Company highlights that the potential quantity and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.

Silver Lake - Long South "Gap"
To the north and east of the Silver Lake Hanging Wall Exploration Target area, the Company is working with external consultants to plan a 3D seismic survey to provide detailed geophysical data input into the targeting of the area directly south of Mincor Resources NL’s McLeay and Moran deposits (previoulys owned by ASX:IGO), hosted at the south end of their Long Operation. This target area will be referred to in future reporting to the market as the “Silver Lake-Long South Gap”. Once the survey is planned the Company will provide an update on the timing of its execution and next steps.
