Tarrina finds more to explore beneath Christmas Gift and across Walparuta

Christmas Gift drilling extends gold system beyond historic mine

Tarrina Resources Limited (ASX:TR8) has turned a six-hole drilling program at Christmas Gift into a broader exploration story, with gold mineralisation now confirmed across more than 1,050 metres of strike compared with roughly 200 metres of historic mining. All six diamond holes intersected gold, including 4.6 metres at 5.42 grams per tonne gold and a narrower 0.5-metre interval at 42.26 grams per tonne.

The strongest results came beneath the historic mine, where the company says gold and zinc mineralisation remain open below the deepest workings. Intersections included 14.5 metres at 2.23 grams per tonne gold and 16.4 metres at 2.06 grams per tonne in one hole, alongside several shorter higher-grade zones. Multiple parallel gold-bearing structures were also identified, supporting the possibility of repeated mineralised shoots, although the release stresses that the results remain preliminary and do not establish a mineral resource.

The latest data builds on the Christmas Gift zinc-copper results, which previously pointed to VMS-style base-metal potential alongside the gold system. Tarrina’s assays indicate copper and zinc zones up to 30 metres wide, with grades reaching 1.65% zinc and 0.23% copper. The company plans further geological mapping and targeting to determine whether the base-metal mineralisation is stratabound and distinct from the structurally focused gold lodes.

Walparuta survey work defines 23 copper-gold drill targets

At Walparuta in South Australia, the company has assembled a large but untested IOCG target package. Soil sampling, magnetic and gravity data, and an extended induced-polarisation survey point to a coherent copper-gold system spanning roughly four to five kilometres, with anomalous geochemistry continuing from surface to depths of up to 700 metres in the broader geophysical corridors.

Eight of nine IP lines contained strong discrete chargeability anomalies, including ten anomalies above 42 mV/V and several above 70 mV/V. Eight of those anomalies coincide with copper and gold soil anomalies, while pathfinder elements including cobalt, uranium, iron, molybdenum and rare earth elements add support to the company’s interpretation of a potentially sulphide-rich IOCG system. The survey work follows the Walparuta soil sampling targets, which identified copper values of up to 2,891 parts per million and gold values of up to 466 parts per billion.

Tarrina has identified 23 high-priority drill targets across a four-kilometre section of the anomalous corridors. The next step is not yet drilling itself: the company must progress land access, government approvals, heritage clearances and a Native Title Mining Agreement with NAWNTAC. The release describes preliminary discussions as positive but gives no certainty on when an agreement will be completed.

Cash preservation becomes part of the exploration plan

The company spent $307,000 on exploration during the quarter and reported net operating cash usage of $505,000, leaving $1.722 million in cash. On the reported quarterly outgoings, Tarrina calculated approximately 3.41 quarters of funding. That is a run-rate measure rather than a guarantee of available funding, particularly as the timing and cost of the planned Walparuta campaign remain unsettled.

The board says it is reducing costs and expenditure while native title discussions progress. Tarrina has also applied for a South Australian PEPR approval and submitted an application for a grant that, if successful, could fund 50% of the planned Walparuta drilling up to $350,000. The announcement contains differing wording on the status and conditions of these approvals, so the eventual funding contribution and drilling timetable remain unresolved.

CEO transition arrives before maiden Walparuta drilling

CEO Dr Greg Partington is due to cease employment on 11 November and will remain available as a technical adviser when needed. The timing places a management transition alongside the company’s attempt to move Walparuta from geophysical targeting into maiden discovery drilling. Tarrina also reported $218,000 in related-party payments during the quarter, including approximately $115,000 for outsourced mineral exploration services connected with the CEO.

For now, the investment case rests on converting broad exploration signals into drill-tested mineralisation. Christmas Gift has delivered repeated gold intersections and a possible second zinc-copper system; Walparuta has delivered an extensive target map. Neither project has yet crossed the more consequential threshold of demonstrating scale, continuity and economic significance through further drilling.
