Latest Developments

2 October 2026: A$6.0 Million Placement

On 2 October 2026, Mamba announced firm commitments to raise A$6.0 million before costs at an issue price of A$0.038 per share through a two-tranche placement, comprising approximately 157.9 million shares. Tranche 1 of 109,789,473 shares is to raise approximately A$4.2 million using the company's existing placement capacity. Tranche 2 of 48,105,264 shares is to raise approximately A$1.8 million and includes 4,342,105 shares to be subscribed for by directors, subject to Shareholder approval at the Annual General Meeting in November 2026.

The company said it will use the funds to grow its technical capability and step up activity across Meeka East, Copper Hills and Poison Hills.

New Murchison Gold Investment and Technical Services Talks

The announcement stated that New Murchison Gold Limited (ASX:NMG) committed to subscribe for A$500,000 of the placement on the same terms as other participants. Mamba and New Murchison also agreed to negotiate in good faith a technical services arrangement, with the scope under discussion including regional data sharing, camp, logistics and equipment support. The company said no specific terms have been agreed and there is no certainty that a binding agreement will be entered into.

Strategic Adviser Appointed

Mamba said it engaged Peter Cook as Strategic Adviser. The announcement described Mr Cook as a geologist and mineral economist with more than 35 years' experience, a founder of Metals X Limited and the founder and Chairman of Westgold Resources Limited. He joins Technical Adviser Peter Schwann, a former Westgold director.

Poison Hills Earn-In

On the same date, Mamba said it entered a binding earn-in agreement over the Poison Hills Project (E51/1957), located about 80 kilometres south-east of Meekatharra. Mamba can earn 51% by funding a minimum of A$250,000 of exploration within 18 months and paying A$50,000 cash and A$150,000 in shares, and may then elect to earn a further 29% (80% in total) by funding a further A$250,000. The company described the project as at an early stage of exploration.

About Mamba Exploration Ltd

Mamba Exploration Ltd is an ASX-listed mineral explorer headquartered in Subiaco, Western Australia. The company is focused on the Murchison region, where it is exploring the Meeka East Gold Project. In an announcement dated 21 September 2026, referenced in the 2 October release, the company reported the recovery of a historical drillhole database for Meeka East showing 165 copper intersections in 47 drill holes along a 3 kilometre corridor at Copper Hills and Lady Alma. The company noted these are historical exploration results and that the corridor remains open along strike and at depth.

Related Sector Context

Mamba operates in ASX-listed mineral exploration in the Murchison region of Western Australia, an area that also hosts gold producers. The company noted that references to nearby projects are for context only and that mineralisation on neighbouring tenements is not necessarily indicative of mineralisation at Poison Hills. The S&P/ASX 200 benchmark was down 0.37% at 1:16 pm AEDT on 23 October 2026.

Risks to Weigh In

Mamba is an early-stage explorer, and the Meeka East intersections are historical results that the company says were recovered from past exploration.
Tranche 2 of the placement and the director participation require shareholder approval at the November 2026 annual general meeting.
The technical services arrangement with New Murchison is not yet agreed, and the company said there is no certainty of a binding agreement.
The Poison Hills earn-in is subject to customary conditions precedent, including necessary approvals and the tenement remaining in good standing.
Rock chip samples at Poison Hills are selective and not necessarily representative of grade, according to the company.

Catalysts on Watch

The 6,000 metre RC program at Meeka East, which the company described as imminent.
Drill targeting at Copper Hills, which the company said is underway.
The annual general meeting in November 2026 to consider Tranche 2, director shares and corporate adviser options.
Progress on the proposed technical services agreement with New Murchison Gold.
Satisfaction of conditions precedent for the Poison Hills earn-in.

Where Things Stand

Mamba shares were trading at A$0.052, down 10.35%, during the 23 October 2026 session, against a 0.37% decline in the S&P/ASX 200 at 1:16 pm AEDT. The company's 2 October 2026 announcement covered a A$6.0 million placement at A$0.038 per share, an investment from New Murchison Gold, the appointment of Peter Cook and the Poison Hills earn-in.
