Dart Mining NL announce that diamond drilling of Lithium-Caesium-Tantalum bearing pegmatites at its Dorchap Lithium project, is scheduled to commence on Friday, 24th March 2023. The approved work program comprises 3,000m of HQ diamond drilling across six pegmatite targets, all of which have demonstrated lithium minerlaisation in previous surface chip sampling. DDH1 to undertake 3,000m of HQ diamond drilling to test six Lithium-mineralised drill targets across the Dorchap Lithium project in Northeast Victoria. Drill targets have all previously demonstrated lithium mineralisation with the key lithium ore minerals spodumene and/or petalite in previously reported surface chip sampling results. The Dorchap Lithium project is fully funded by Dart Mining's joint-venture partner, Sociedad Química y Minera. Dart Mining has granted SQM, the right to sole fund exploration expenditure totalling A$12m over the next 6 years. During the first earn-in period, SQM may earn an initial 30% interest in the Dorchap Lithium Project by sole funding exploration expenditure of A$3m. Drilling scheduled to begin on Friday 24th March 2023. Dart Mining geologists first identified the lithium prospectivity of pegmatite dykes in the Dorchap Range in 2016 and set about acquiring exploration leases across the region. These are the first recorded lithium pegmatites identified in Victoria, and are believed to have been sourced from the nearby Mount Wills Granite. A regional sampling program consisting of 826 samples has identified a strong fractionation trend across the Dorchap Range,
resolving a 20×12 km zone of strongly fractionated pegmatites bearing enriched Li, Cs, Ta, Be and Sn mineralisation. Dart Mining's chip sampling program has seen some rewarding results, including: 16m at >530 ppm Cs2O, 0.32% Li2O and 104 ppm Ta2O5, and grab samples at 1.57% Li2O and 0.1% Ta2O5 at the Bluejacket Dyke in Glen Wills, along with 10m at 0.95% Li2O from the Eagle Dyke and 10m at 1.38% Li2O from the Holloway Dyke (Dorchap Range), and 10m at 1.22% Li2O from Scrubby Dyke, 1m at 838 ppm Cs2O and 0.46% SnO2, and a grab sample at 9.98% SnO2 from elsewhere in the Dorchap Range. The initial, short drilling program in 2019 has been followed by an airborne LiDAR mapping program in early 2021, which has allowed additional, detailed mapping of pegmatite dykes that were previously overlooked in pockets of dense bush across the Dorchap Range.
