Taruga (ASX:TAR) lines up seven Kol Mountain targets in PNG

A 4.8km copper-gold soil anomaly that has never been drilled is suddenly the centre of the story

Taruga Minerals (ASX:TAR) has just put a proper structural framework around its Kol Mountain copper-gold project in East New Britain, PNG, and the picture that emerges is more interesting than the typical early-stage explorer update.

Southern Geoscience Consultants ran a tenement-wide lithostructural and magnetics study across EL 2513 and came back with 25 targets, seven of them ranked high priority. The standout is the Agadul (Bukuam) porphyry, a 4.8km copper-gold soil anomaly first defined in the 1980s and never once drill tested. Sitting next to it is the Agadul (Kapea) Shear Zone, where historical rock chips returned grades as high as 63.5g/t gold.

What makes this more than a paper exercise is that Taruga’s field team is already on the ground. With Makolkol community contractors working alongside the geologists under the May 2026 MoU, the company has converted a target generation study into an active campaign. For a micro-cap explorer in PNG, having the social licence and the field team in motion at the same time is the harder half of the equation.

Why an undrilled 4.8km soil anomaly matters more than the headline grades

The 63.5g/t rock chip is the eye-catching number, but the real prize here is the Bukuam porphyry footprint. BHP, CRA (Rio Tinto) and Frontier Resources all worked this ground in past decades and all of them mapped a coherent 4.8km copper-in-soil anomaly. None of them drilled it.

That is unusual. A 4.8km surface footprint in a district that hosts Ok Tedi, Wafi-Golpu and Frieda River is exactly the kind of target a major would normally test. The skeptical read is that PNG’s permitting and access challenges, not geology, kept the drill rigs away. Taruga’s MoU with the Makolkol Land Group is what unlocks that.

If the company can get a maiden drill program away in the second half of 2026, this is the first time anyone will actually know what sits beneath the anomaly. That is a binary outcome, which is both the opportunity and the risk.

The Kapea high-grade shear is the near-term sweetener

Sitting inside the broader Bukuam footprint is the Kapea Shear and Skarn Zone. Historical channel sampling returned 60m at 1.5g/t gold including 2m at 21.3g/t, and 55m at 3.2g/t including 5m at 13.1g/t. Three shallow CRA diamond holes from 1989 also hit mineralisation, including 6m at 2.2g/t from 36m.

Those are genuinely strong numbers for surface and shallow work. The system is structurally controlled, open along strike and at depth, and Taruga is currently extending the trench and rock chip sampling to validate it. We think Kapea is the near-term news flow generator. It gives investors something to watch while the harder porphyry drill targets are being defined.

Esis adds a second leg, but it is still a long way from a resource

The SGC study also flagged priority targets adjacent to the Esis intrusive complex in the south of the tenement, including the Pele and Nombung prospects. Historical sampling at Esis already shows coherent copper and gold anomalism along intrusive contact zones.

It is also worth noting that nothing at Kol Mountain has a JORC resource attached to it. This is exploration at the target generation stage, with the next 12 to 18 months focused on mapping, geochemistry, possible 3D magnetic inversion modelling, and ultimately a maiden drill program. Investors buying TAR today are buying the option, not the outcome.

The Investors Takeaway for Taruga Minerals

Taruga has done the hard groundwork. A structural framework, seven ranked targets, a community partnership, and a field team in place. The next catalyst that actually moves the share price is going to be drilling, and specifically the first holes into the Bukuam porphyry.

Until then, expect a steady drip of mapping and geochemistry results that will help refine the drill collars. Investors who want broader exposure to early-stage ASX-listed explorers can find more coverage at stocksdownunder. The Kol Mountain story is genuinely interesting, but it is also genuinely binary, and that needs to be priced in.
