TG Metals Limited announced the commencement of a Slingram Moving Loop Transient Electromagnetic (SMLTEM) geophysical survey as part of the recommended outcomes from the previously announced geophysics review (ASX announcement 14 September 2022, "Priority Nickel Sulphide targets defined at Lake Johnston") over approximately 30-kilometre strike of the Lake Johnston Greenstone Belt in Western Australia, south of the Maggie Hays-Emily Anne nickel sulphide mining centre. The aim of the survey is to detect conductive bodies at depth which are indicative of nickel sulphide mineralisation. Multiple targets have been defined by existing geophysics, surface geochemistry and drilling, conducted by past explorers.

The SMLTEM survey will be the first of its kind, modern high-powered ground EM, to test the prospective ultramafic host lithologies extending from the Maggie Hays ­ Emily Anne mining centre. The proposed survey consists of 322 stations as the initial test of eight priority areas. The survey is expected to take approximately 10 days to complete (weather permitting) and is being managed by Southern Geoscience Consultants, with field activities carried out by High Power EM Geophysical Services.

Heritage and environmental clearances for areas with defined drill targets have been scheduled for Fourth Quarter 2022. Applications for Program of Works Approval will be made on completing of these clearances, with updates provided to the market as progress is made. Flora and Fauna surveys are due to commence at the end of October.

Following the results of this SMLTEM program, any conductors identified will be assessed for follow-up geophysical work or drill testing. Any new drill targets will be included with other targets, already prioritised for drilling which is planned be conducted over the coming months following the necessary grant of approvals including heritage and environmental clearances.
