Critical Resources (ASX:CRR) positions Halls Peak as a multi commodity discovery pipeline with gold antimony and silver leverage

Managing Director Tim Wither of Critical Resources (ASX:CRR) joins MarketOpen today to discuss the latest Halls Peak Project update, with a focus on petrographic confirmation at Amoco, high grade silver continuity at Gibsons, and access progress at the Mayview Antimony Prospect, and what these results mean for targeting, sequencing, and risk reduction across the district scale portfolio.

What exactly has the Amoco petrographic work confirmed and why does it matter for your targeting model?

The petrographic work on maiden drill samples confirms that Amoco hosts a late stage shallow orogenic gold antimony silver bearing system that overprints earlier VHMS mineralisation, and that gives us a clearer mineralisation style and structural context for follow up targeting.

The textures, mineral chemistry and alteration signatures are consistent with a lode style system and align with the model we outlined in the release.

This shifts Amoco from a conceptual target to one supported by detailed mineralogical evidence and recommended follow up drilling.

The important point for investors is that the petrography supports further drilling of the surface high grade gold, antimony and silver zones along strike and at depth using a refined structural model.

How should investors interpret the Amoco surface gold, antimony and silver sample results alongside the drilling and petrographic findings?

The outcrop and float samples reported at Amoco returned values up to 17.9 g per tonne gold, 0.7 percent antimony and 53.2 g per tonne silver, and those results sit alongside the petrographic confirmation of an orogenic gold antimony system.

We treat surface sampling as a targeting input rather than a resource statement, but when those values are consistent with the mineralisation style identified in drill chips, they become more useful for prioritising where to drill next.

What matters operationally is that these surface results are now being integrated into the structural and geological model to define priority zones for the next drilling stage rather than being viewed in isolation.

What is the practical significance of the stacked silver lode model at Gibsons for resource growth and drill planning?

Gibsons hosts an Inferred Mineral Resource of 840,000 tonnes at reported zinc, lead, copper, silver and gold grades, and the drilling database shows multiple stacked silver rich lodes with more than 130 samples above 100 g per tonne silver and ten samples above 940 g per tonne silver.

Up to nine mineralised horizons have been modelled, with three carrying consistently ultra high silver grades above 900 g per tonne, and some of the highest grade intervals sit outside or adjacent to current resource wireframes.

The current resource remains open along strike and at depth, and the stacked lode geometry provides defined targets for down dip extensions and step out drilling aimed at expanding both tonnage and grade.

The release notes two distinct silver mineralisation styles at Gibsons, how does that influence your exploration approach going forward?

The announcement sets out that Gibsons contains both massive sulphide hosted silver associated with zinc lead copper lodes and a separate black shale hosted silver style where silver occurs as tetrahedrite disseminated through altered shale.

The high grade PMR027 interval of 1.6 metres at 1,900 g per tonne silver with minimal base metals is specifically cited as evidence of that second structural system.

From an execution standpoint, this means future drilling is not limited to one host setting, because we are targeting both down dip extensions of the high grade sulphide lodes and untested shale horizons that represent a parallel silver system within the same project area.

How should investors assess the Mayview antimony prospect given the high grade samples and current land access status?

Mayview sits adjacent to the Hillgrove antimony gold operations and field mapping has confirmed antimony gold mineralisation in historic workings, supported by rock chip assays up to 52.3 percent antimony and gold values up to 2.71 g per tonne.

At present, the gating factor is land access, and the release is clear that engagement with landholders is ongoing and that a low impact soil geochemistry survey is planned once access is secured.

The key point is that Mayview is being advanced in parallel through permitting and access agreements so that low impact geochemical work can proceed in a defined corridor of mapped workings when approvals are in place.

District scale sequencing across three prospects

In practice, the Halls Peak strategy is being executed as a staged, multi prospect program where Amoco drilling targets are refined using petrography and structural modelling, Gibsons drilling is directed toward extending defined high grade silver lodes and adjacent horizons, and Mayview is progressed through land access and low impact geochemistry before drill decisions are made.

Critical Resources Managing Director Tim Wither is positioning the portfolio as a district scale, multi commodity pipeline where each prospect advances through targeted programs built on technical results already reported, rather than broad step out activity without supporting data.
