ASX Release

29 November 2023

Recommencement of Field Activities – Dorchap Lithium Project

Dart Mining NL (ASX:DTM) (“Dart Mining” or “the Company”) is pleased to announce that the success reported from Phase 1 diamond drilling has secured ongoing exploration support as part of the Sociedad Química y Minera de Chile S.A (NYSE: SQM ) $12 million SQM earn-in agreement with Dart Mining. Field activities have re-commenced across the project area with multiple field teams operating across high priority target areas. Works have commenced within the central Gosport region, with mapping and sampling of outcropping pegmatites.

Highlights Include:

• Ongoing support from SQM for Earn In JV exploration efforts

• Multiple field crews in operation across high priority targets

• 100’s of untested pegmatite targets to be mapped and sampled

Field activities are focusing on the accelerated testing of pegmatite targets identified by the Lidar survey completed in 2021 ( 27 October 2021: “LiDAR Points Towards Increase in Lithium Pegmatites” and 18 “ March 2021: LiDAR Data Acquisition over Strategic Projects”) . Over 220 previously unmapped outcrops bearing similar features to known pegmatite dykes were identified, with 100’s remaining untested.

Work is also progressing on the approvals process for the commencement of diamond drilling at the Gosport Prospect within the Dorchap Lithium Project. Permitting is currently going through the submission and approval of a standard work plan to allow for the establishment of access and drill pads for the drill testing of the Gosport Dyke Group. The Gosport region is a central zone with a high number of prospective pegmatite dykes in close proximity with demonstrated Lithium potential through initial high-grade rock chip sampling within exploration license EL5315.

Chairman, James Chirnside commented: “The Dorchap Lithium project remains a top priority of Dart Mining. The acceleration of permitting and field activities as well as continuing support from SQM on the project, are testament to our confidence in, and prospectivity of, the region. These field activities build on our existing understanding of the system as we seek to increase the number of prospective targets for future drill testing.”

Dorchap Lithium Project Summary

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 ( Dart Mining ASX May 2016 ; Dart Mining ASX August 2016 ). 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 km ×12 km zone of strongly fractionated pegmatites bearing enriched Li, Cs, Ta, Be and Sn mineralisation ( Dart Mining ASX July 2021 ).

Dart Mining’s chip sampling program has yielded 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 ( Dart Mining ASX July 2021 ). The initial short drilling program in 2019 has been followed by an airborne LiDAR mapping program in early 2021 ( Dart Mining ASX March 2021 ), which has allowed additional, detailed mapping of pegmatite dykes that were previously overlooked in pockets of dense bush across the Dorchap Range.

About Dart Mining

Dart Mining (ASX: DTM) has the aim of evaluating and developing several historic goldfields, as well as substantiating a new porphyry province in Northeast Victoria. The area is prospective for precious, base, and strategic metals. These include Lithium, Gold, Silver, Copper, Molybdenum, Zinc, Tungsten, Tin, Tantalum, and a host of other important minerals. Dart Mining has built a strategically placed gold exploration footprint in the Central and Northeast regions of Victoria, where historic surface and alluvial gold mining indicates the existence of potentially significant gold endowment.
