Culpeo Secures Access to Vista Montana Clearing Way for 2,000m Maiden Drill Programme
Key Takeaways
- Culpeo Minerals has secured land access to Vista Montana and will commence a four-hole, 2,000m maiden diamond drilling programme within the next two weeks, targeting the first-ever subsurface test of the prospect.
- Vista Montana sits 1km north-east of the Lana Corina Cu-Au-Ag-Mo discovery and shares the same demagnetised geophysical signature that coincides with Lana Corina's significant copper and molybdenum intercepts.
- Historic Lana Corina drilling has returned intercepts including 454m at 0.96% CuEq from 90m and 169m at 1.23% CuEq from 239m, establishing the corridor's porphyry-style prospectivity that Vista Montana is now being tested against.
- The drilling rig will mobilise directly from El Quillay South to Vista Montana once the current 200m hole completes, ensuring a continuous newsflow pipeline of results through early September 2026.
- An induced polarisation (IP) geophysics survey at Lana Corina is expected to commence within days, designed to refine existing targets and identify additional mineralised zones along the 3km structural corridor.
Culpeo Minerals has secured access to the Lana Corina Project and Vista Montana Prospect in Chile, clearing the way for a maiden diamond drilling programme. The initial four-hole, 2,000m diamond drilling programme is expected to commence within the next two weeks. Vista Montana sits approximately 1km north-east of the Lana Corina Cu-Au-Ag-Mo discovery and is interpreted to form part of the same north-northeast trending mineralised corridor. This drilling has the potential to materially expand the Lana Corina discovery. Meanwhile, diamond drilling continues at El Quillay South — once the current 200m hole completes, the rig mobilises directly to Vista Montana.

The maiden Vista Montana drilling programme explained
The four-hole, 2,000m diamond drilling programme has been designed to test multiple high-priority targets and provide the first subsurface assessment of the prospect. This is genuinely maiden territory — Vista Montana is undrilled, and the programme represents the first attempt to understand what sits beneath the surface indicators.
Culpeo is maintaining operational momentum. Drilling continues at El Quillay South within the Fortuna Project. Once the current 200m diamond drillhole is complete, the drilling rig will mobilise directly to Vista Montana to commence the maiden programme. For investors, this means a continuous pipeline of newsflow over the coming months — results from El Quillay South, followed by drilling updates from Vista Montana, followed by assay results as they become available.
The programme may be extended subject to geological observations and initial results from the first four holes.
The targets at Vista Montana were defined through a combination of:
- Ground magnetic surveying
- Geological mapping
- Geochemical soil sampling
- Surface rock chip sampling
This work identified numerous copper and gold mineralised quartz veins and breccias within the target corridor. The corridor is also characterised by phyllic alteration — comprising quartz, sericite, and pyrite — observed at surface. This alteration assemblage can be associated with porphyry-style mineralisation and supports Vista Montana’s ranking as a priority drill target.
Why the Lana Corina track record matters
Vista Montana’s target areas coincide with large demagnetised zones — the same geophysical signature seen at Lana Corina, which has returned significant copper and molybdenum intersections. For an investor, this matters because geophysical signatures provide a way to extend exploration beyond a single drillhole. If Vista Montana shares the same structural and alteration characteristics as Lana Corina, and Lana Corina has delivered long intercepts of meaningful grades, Vista Montana becomes more than a speculative target. It becomes a logical extension.
The historic Lana Corina drilling results demonstrate the corridor’s prospectivity:
| Drillhole | Intersection | Grade (CuEq) | From (depth) |
|---|---|---|---|
| CMLCD014 | 454m | 0.96% CuEq | 90m |
| CMLCD002 | 257m | 1.03% CuEq | 170m |
| CMLCD003 | 173m | 1.11% CuEq | 313m |
| CMLCD010 | 169m | 1.23% CuEq | 239m |
| CMLCD001A | 104m | 0.83% CuEq | 155m |
| CMLCD005A | 81m | 1.14% CuEq | 302m |
These are historic results from Lana Corina, referenced to demonstrate the corridor’s prospectivity. Vista Montana remains undrilled — no intercepts have been reported from the prospect.
Geoff McNamara, Non-Executive Chairman
“The re-establishment of operations at the Lana Corina Project allows us to move directly to maiden diamond drilling at Vista Montana, which has the potential to materially expand the Lana Corina discovery. This drilling, coupled with an imminent geophysics survey, will further refine existing targets and potentially identify new targets along the highly prospective structural corridor.”
What the quote underscores is management’s view that Vista Montana is not a standalone target. It is part of a 3km mineralised corridor linking the two prospects — a label that appears in the project’s map figure annotations — and the drilling programme is designed to test multiple high-priority targets within the interpreted mineralised corridor.
Understanding porphyry copper systems and the corridor concept
A porphyry copper system is a type of large-tonnage, disseminated mineralisation formed by hydrothermal fluids circulating through fractured rock above a cooling magma body. These systems can host hundreds of millions to billions of tonnes of mineralisation, and they are the source of much of the world’s copper supply. The grades are typically lower than vein-hosted deposits, but the sheer volume compensates. That is why porphyry systems are economically significant.
A mineralised corridor refers to a structural zone — often along a fault or intrusive contact — where mineralisation is interpreted to extend over distance. In this case, Vista Montana sits 1km along strike from Lana Corina. Proximity along strike to a known discovery raises the prospectivity of an undrilled target because the same geological conditions that deposited copper and molybdenum at Lana Corina may have operated at Vista Montana.
Demagnetised zones are areas where the magnetic signature of the host rock has been weakened or destroyed. This can occur when hydrothermal fluids alter the rock during mineralisation. At Lana Corina, demagnetised zones coincide with the known copper and molybdenum intercepts. At Vista Montana, similar demagnetised zones have been identified — which is why the geophysics are being used to prioritise drill targets.
CuEq (copper equivalent) is a way of combining copper, gold, silver, and molybdenum into one comparable grade figure. It converts the value of all metals into an equivalent amount of copper, using assumed commodity prices and metallurgical recoveries. This allows investors to compare intercepts that contain multiple metals without having to calculate the relative contributions of each element manually.
For investors, the combination of porphyry-style alteration, a structural corridor linking two prospects, and geophysical signatures that match a known discovery makes Vista Montana a priority drill target. The question is not whether the system exists — the question is how far it extends.

What comes next for Culpeo investors
The near-term newsflow is structured around two active drilling programmes and an upcoming geophysics survey. Drilling at El Quillay South is expected to complete within the next two weeks. The rig will then mobilise directly to Vista Montana, with the maiden drilling programme expected to commence in early September 2026. Results from El Quillay South will arrive first, followed by drilling updates from Vista Montana, followed by assay results as they become available.
An induced polarisation (IP) survey at Lana Corina is expected to commence in the coming days. IP surveys measure the electrical chargeability of the subsurface, which can help identify zones of disseminated sulphide mineralisation — the hallmark of porphyry systems. The survey is designed to refine current targets and identify additional areas of interest along the corridor.
The upcoming catalysts for investors are:
- Completion of current 200m diamond drillhole at El Quillay South
- Rig mobilisation directly to Vista Montana
- Commencement of four-hole, 2,000m maiden programme (early September 2026)
- IP survey underway at Lana Corina to refine and generate targets
