Tambourah Faces Strategic Shift After SQM Exits Julimar North Earn-In

Tambourah King Gold Mineralisation Extended

Tambourah Metals Ltd (ASX – TMB) has reported encouraging assay results from reverse circulation (RC) drilling at its flagship Tambourah King gold prospect. The recent program extended significant gold mineralisation over a 200-metre strike length, with notable intercepts including 3 metres at 2.99 grams per tonne (g/t) gold from 36 metres and 2 metres at 3.68 g/t from 47 metres. These results reinforce the prospect’s potential and underpin ongoing exploration efforts to define a resource.

Geological mapping and soil sampling have identified potential extensions south of Tambourah King and the Federal prospects, with selective drilling already underway to test these anomalies. Additionally, drilling has commenced at nearby Alexandria and Young Australian prospects, with assay results awaited.

Beatty Park South and Tambina Projects Advance

At the Beatty Park South gold prospect, Tambourah completed a 26-hole aircore drilling program targeting historic high-grade gold intersections, some dating back to the 1990s. This marks the first drilling in the area since that period, aiming to confirm historic anomalies such as 5 metres at 22.9 g/t gold. Assay results from this program are pending, with further drilling planned based on outcomes.

Meanwhile, first-pass reconnaissance sampling at the Tambina Gold Project identified gold values up to 4.3 g/t from weathered ferruginous conglomerate layers within a sedimentary basin. This supports the prospectivity of the palaeo-placer gold target, with additional surface sampling planned to delineate supergene enrichment zones for future drill testing.

Critical Minerals Confirmed at Speewah North

Tambourah’s exploration at the Speewah North project in the Kimberley region has confirmed high-grade antimony (up to 4.54%), silver (517 ppm), and copper (3.62%) through rock sampling along the Chapman–Catto’s corridor. These results validate historic anomalies and highlight the potential for critical mineral deposits within the Speewah Dome, a geologically complex area with known fluorite and vanadium-titanium deposits nearby.

The company plans to extend outcrop mapping and sampling ahead of a maiden drilling campaign, also targeting historic antimony anomalies at Barton’s West and Joe Fisher prospects. This diversification into critical minerals aligns with growing market demand for these strategic elements.

Corporate Developments and Financial Position

Tambourah announced the appointment of Mt Terry Topping as CEO, bringing extensive experience in gold exploration and management, including leadership roles at Kairos Minerals and Rumble Resources. This leadership change aims to accelerate project development and corporate growth.

Financially, the company raised approximately $947,720 before costs through a private placement and entitlement offer during the quarter. Tambourah ended June 2025 with $1.898 million in cash, having spent $248,000 on exploration activities. The company continues to rationalise its tenement portfolio and engage potential joint venture partners to focus on core assets.

Strategic Outlook

Tambourah Metals is advancing multiple gold and critical mineral projects across Western Australia, with drilling and sampling programs ongoing or planned at Tambourah, Beatty Park South, Tambina, and Speewah North. The recent termination of the earn-in agreement with SQM at the Julimar North project refocuses the company’s efforts on its core holdings. Pending assay results from recent drilling will be critical in shaping the next phase of exploration and potential resource definition.
