FIELD RECONNAISSANCE CONFIRMS ANTIMONY AT TALLANDOON

Dart Mining NL (ASX:DTM) (“Dart Mining” or “the Company”) is pleased to announce the initial observations from a field reconnaissance visit to the Tallandoon Antimony prospects within the Company’s 100% owned Exploration Licences EL006300 & EL007754 in the North East of Victoria.

ANNOUNCEMENT HIGHLIGHTS

• Antimony mineralisation observed in waste rock from the historic “Carry On” antimony Mine (Figure 1)

• Antimony mineralisation also observed within waste rock of the historic “The Antimony Mine” ( Figure 2)

• Visual inspections indicate significant Stibnite presence, with Initial pXRF results confirming elevated antimony levels.

• 20 samples have been submitted for multi-element analysis.

• Field observations support previous Dart grab sampling from the “Ellis Antimony” Mine which returned 6.48% Sb (ASX: DTM July 2020)

DTM’s Chairman, James Chirnside, commented : “Field activities conducted at the Tallandoon Historic Goldfield reconfirm the prospectivity of the Tallandoon area as a very prospective region for antimony mineralisation. The Company eagerly awaits the assay results to confirm the concentration of antimony, following positive Antimony identification from initial pXRF results.”

SAMPLING DETAILS

Mapping and sampling were conducted over 2 days, with 20 samples taken from waste dumps surrounding the historic mines. Material discarded as waste from the historic mining activities was dominated by Quartz with sporadic sulphide mineralisation observed. 2 key samples were collected, (217566 – Figure 1 and 217558 -Figure 4) which both showed significant stibnite mineralisation within the host quartz rock.

Sample 217566 included large, elongated crystals and massive sulphide occurrences of fine grained Stibnite, within the quartz host. Sample 217558 mineralisation was observed as a 2 parallel veinlets of stibnite mineralisation also within quartz.

The presence of antimony as massive sulphide and crystalised form within waste rock dumps of two historic mines separated by 3.4km confirms the prospectivity and supports the initial sampling completed by Dart in 2020 (ASX: DTM July 2020).

TALLANDOON PROJECT DETAILS.

The Tallandoon Antimony Prospect is an area of historic antimony mining conducted from 1914 through to 1945. The area of interest is dominated by biotite schists, with numerous granitic dykes intruding through the area. Mineralisation is dominantly associated with dyke boundaries (Carry On Mine) and quartz reefs (The Antimony Mine & Ellis Antimony Mine), with abundant arsenopyrite, sphalerite and Galena along with Stibnite (antimony bearing mineral).

Large scale secondary offset faults crosscut the region caused by the regional Lochart Gap Fault in the North East of the region. Local scale quartz reefs are formed in a North West – South Eastly orientation, likely as a series of large scale tension vein arrays to the north south prospect scale faulting corridor forming between the secondary offset structural set ( Figure 2). The Carry On Mine is located on a granitic dyke intrusive, with massive sulphide Stibnite mineralisation reported on both contacts up to 3 to 4 feet (0.9m – 1.2m wide (Mining & Geological Journal Vol3, No 1, March 1947).

About Dart Mining

In August 2024 Dart Mining (ASX:DTM) entered into a binding agreement to purchase the Triumph Gold Project, this is Dart’s first step into an advanced intrusion related gold system project in Queensland. Dart will look to develop a regional presence in Queensland through advanced stage intrusion related and epithermal gold projects. Dart Mining will continue to evaluate several historic goldfields in Central and Northeast Victoria including the Rushworth Goldfield and the new porphyry and lithium province in Northeast Victoria identified by Dart. The area is prospective for precious, base, and strategic metals including Lithium, Gold, Antimony, Silver, Copper, Molybdenum, Zinc and Tin. 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.
