Over 10,000 Metres Drilled with 27.48 g/t Gold Intercept at Jims

Exploration Momentum at Central Tanami

Tanami Gold NL (ASX – TAM) has maintained a robust exploration pace during the September 2025 quarter, drilling over 10,000 metres across key prospects within the Central Tanami Project (CTP). The company’s 50% joint venture with Northern Star Resources has focused efforts on the Jims Gold Mine, Groundrush Gold Mine, Western Dolerite, and Defa prospects, advancing the understanding of mineralisation in this prolific Northern Territory gold region.

At Jims, the highlight of the quarter, final assay results from an 18-hole Reverse Circulation Pre-collar/Diamond Core Tail drilling program revealed several significant gold intercepts. These include a standout 2 metres grading 27.48 grams per tonne (g/t) from 212 metres depth, alongside other substantial intercepts such as 7.3 metres at 6.74 g/t and 8 metres at 5.6 g/t. These results reinforce the potential for down-dip and northerly extensions of the Jims Main zone, a historically productive area with mining activity dating back to the mid-1990s.

Strategic JV Ownership Change

In a significant corporate development, Mount Gibson Iron Limited announced in July 2025 its agreement to acquire Northern Star’s 50% interest in the Central Tanami Project Joint Venture, along with adjacent exploration tenements, for a cash consideration of A$50 million. This transaction positions Mount Gibson as a key stakeholder in the project’s future, potentially reshaping operational dynamics and investment strategies. Tanami retains its 50% interest and continues to fund exploration activities alongside its JV partner.

Financial Position and Ongoing Work

Tanami Gold reported a solid cash position of A$16.013 million at the end of the quarter, providing a stable financial foundation to support ongoing exploration and development. The company’s cash flow reflected continued investment in exploration, with payments for drilling and evaluation activities consistent with its growth objectives.

Meanwhile, drilling programs at Groundrush and Western Dolerite have been completed, with assay results pending. These programs aim to enhance confidence in mineral resource estimates and explore extensions of known mineralisation. Similarly, drilling at the Defa Prospect resumed, targeting gold mineralisation hosted within quartz veins and sulphides, with results expected in due course.

Resource Updates and Compliance

Efforts to update the Central Tanami Project’s Mineral Resource estimates are underway, aligning with the 2012 Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC Code). These updates, managed by MoJoe Mining Pty Ltd, incorporate revised geological models and optimisation techniques to better define the economic potential of the deposits.

Importantly, the joint venture reported no lost time injuries during the quarter, reflecting a strong safety culture amid active field operations. Heritage and environmental clearances remain in place, supporting the continuity of exploration activities.
