Mamba Identifies More Than 20km of Gold Strike at Meeka East

8 May 2026 | Western Australia - Mamba Exploration has reported new soil sampling results from its Meeka East Gold Project in Western Australia’s Murchison region, identifying multiple gold targets across more than 20km of prospective strike.

The company said extensional soil sampling has extended the gold occurrence south of the historical sample area at the 140’ Well prospect, while infill results have helped define an initial drilling target. The identified mineralised trend at 140’ Well is interpreted as a southern extension of Great Boulder Resources’ Mulga Bill trend into Mamba’s Meeka East Gold Project.

Mamba said the soil sampling program confirmed its “Gold in Sediments” geological concept, with anomalous gold assays located in stratigraphic trends on either side of cross-cutting dolerites in several locations. The work also identified three additional major stratigraphic anomalies: New Australian, Lady Maud and Bella.

The company completed more than 1,300 fine soil samples across nearly 25km² of prospective ground. Sampling was designed to test prospective stratigraphy and structures across the project, excluding the Mt Yagahong site.

Mamba Executive Director Matt Freedman said the results continued to support the company’s geological model and that the Lady Maud area was particularly encouraging, with consistent elevated gold-in-soil values across multiple sections. He said the results had created new priority drill targets further south and extended the project’s potential overall strike length to about 20km.

Why it matters: Soil sampling is an early-stage exploration tool, but these results are important because they appear to define coherent gold trends rather than isolated spot values. Mamba said the anomalous results form tight clusters, with the most significant results at Lady Maud tracing across multiple sections and defining a clear trend consistent with two or more target stratigraphic units.

The strongest soil values reported included 22.8ppb gold at Lady Maud, 14.1ppb gold and 12.3ppb gold at New Australian, and 11ppb gold at Bella. The company used a 2 standard deviation anomalous cut-off of 2.5ppb gold.

Mamba has also been awarded up to $90,000 through the Western Australian Government’s Exploration Incentive Scheme to support a planned $180,000 drilling program. The company said the process for heritage approvals and Programme of Work lodgement is now underway, with drilling to commence as soon as practicable once approvals are received.

The initial drilling focus is expected to be the northern 140’ Well area, with approximately 15 reverse circulation holes for 1,800m planned along the initial trend. Mamba is also submitting a Programme of Work for an expanded program of up to 50 holes to test broader anomalies across Meeka East, including Lady Maud, New Australian and Bella.

For Western Australia’s gold exploration sector, the results add another early-stage target in the Murchison, with Mamba now moving from geochemical targeting toward first-pass drilling.
