MB Gold reaches assay season with new Marble Bar targets in sight

Phase 2 drilling leaves MB Gold waiting for assays

MB Gold Limited (ASX:MBG) has reached the most consequential checkpoint of its first listed exploration campaign: the Phase 2 reverse-circulation program at the Marble Bar Gold Project is complete, but the assays are still to come. The program targeted extensions of known mineralisation at Twin Veins and included the first drilling at Razorback, with results expected during October.

The work followed the company’s 6,000m Phase 2 drilling launch, which targeted Twin Veins extensions and maiden holes at Razorback. MB Gold’s quarterly report says the campaign was designed to build on Phase 1 results and test new targets, but it does not yet provide any Phase 2 assay results or evidence of continuity beyond the earlier intercepts.

Twin Veins East adds a second exploration thread

The strongest completed results remain at Twin Veins East, where drilling returned 2 metres at 6.73 grams per tonne gold from 39 metres, including 1 metre at 13.12g/t, in hole 26MBRC031. A separate hole returned 3 metres at 2.31g/t from 82 metres, while 26MBRC034 delivered 1 metre at 6.8g/t from 76 metres.

Those results sit around 500 metres east of the central Twin Veins area along a 1.5-kilometre gold-in-soil anomaly. The company describes the area as a new gold zone, but also says more drilling is required to establish continuity and determine whether the mineralisation has a high-grade plunge control. That is why the Twin Veins East zone matters less as a standalone intercept than as a test of how far the system may extend.

DDIP survey points to deeper targets

Surface drilling is not the only part of the exploration story. MB Gold’s government co-funded dipole-dipole induced polarisation survey identified chargeability anomalies across the project, including at depth beneath Twin Veins East, beneath Douglas Find and along a magnetic trend west-northwest of Twin Veins.

The survey comprised seven lines of roughly three kilometres, using 200-metre-spaced dipoles. MB Gold says the anomalies may reflect hydrothermal alteration or disseminated sulphide mineralisation, but geophysical responses are targets rather than discoveries. At Murphy Well, the company’s interpretation is that two earlier deep diamond holes did not test the principal chargeable zone. The multiple DDIP anomalies now provide a basis for deeper targeting, with a 2,000-metre diamond program subsequently supported by up to $220,000 in government co-funding and scheduled for November.

Cash funds roughly four quarters of exploration

MB Gold reported $4.84 million in cash and cash equivalents at 30 September, down from $5.97 million at 30 June. It spent approximately $1.19 million on exploration during the quarter, primarily on more than 4,300 metres of RC drilling, and recorded net operating cash outflow of $1.13 million. On the quarterly figures, the company estimates funding of 4.29 quarters at the reported rate of expenditure.

That runway is a useful buffer, not a production forecast. MB Gold remains an exploration company with no mining or development activity, and its annual report recorded a $1.07 million loss for the period ended 30 June, including non-cash items. The next financial question is therefore inseparable from the geological one: whether upcoming assays justify accelerating deeper work before the cash balance becomes the more pressing target.
