Tusker Minerals Accelerates Exploration with New Tenements and High-Grade Discoveries

Exploration Breakthroughs in Cameroon

Tusker Minerals has made notable strides in its Cameroon portfolio during the December 2025 quarter, confirming the presence of Kasiya-style flake graphite alongside significant rutile mineralisation. The Central Rutile Project now boasts a dual-commodity system, with assay results revealing graphite grades up to 0.60% total graphitic carbon and rutile zones reaching 0.88% from surface samples.

These findings come as part of a comprehensive exploration campaign that included the collection of 608 soil samples and targeted hand-auger drilling at the Bounde and Nganda licences. The drilling program, utilising robust tungsten-carbide reinforced equipment, is systematically testing a historic 70 by 15-kilometre rutile corridor mapped by BRGM, marking the first modern evaluation of this highly prospective zone.

Strategic Expansion and Infrastructure Development

In a significant move to consolidate its position, Tusker completed the acquisition of the Yaoundé West Rutile tenements, expanding the Central Rutile Project’s footprint to approximately 8,782 square kilometres. This expansion covers geology with strong rutile potential and areas with a history of residual mining.

Complementing its exploration efforts, Tusker has established a corporate office in Cameroon and is on track to commission a purpose-built heavy-mineral sands laboratory in Yaoundé by early 2026. This facility is expected to reduce assay costs and turnaround times substantially, enabling more efficient and continuous exploration activities.

Malawi Portfolio Under Strategic Review Amid Strong Results

Meanwhile, Tusker has initiated a strategic review of its Malawi rare earth portfolio to explore value realisation options. This review is timely given the increasing geopolitical focus on securing diversified supply chains for critical minerals.

Surface sampling at the Tundulu Project has extended high-grade gallium mineralisation, with values up to 82 g/t Ga₂O₃, alongside encouraging rare earth elements, phosphate, and niobium. Similarly, the Machinga Project’s sampling confirmed gallium as a valuable addition to existing heavy rare earth and niobium mineralisation, with results reaching 75.28 g/t Ga₂O₃.

Corporate Transformation and Financial Position

Reflecting its evolving strategic focus, the company formally changed its name from DY6 Metals to Tusker Minerals, signalling its ambition as a leading African-focused critical minerals explorer. The recruitment and training of a local Cameroonian workforce further demonstrate Tusker’s commitment to sustainable in-country operations.

Financially, Tusker ended the quarter with approximately A$2.2 million in cash and reported direct exploration expenditure of A$0.96 million. The company also issued shares and performance rights as part of the Yaoundé West transaction, underpinning its growth strategy.
