RM Research Outlines Potential Rerating of Culpeo Minerals Driven by Chilean Copper Projects
ASX-listed Culpeo Minerals maintains two copper projects in Chile - Lana Corina and Fortuna - both located in Chile’s Coastal Cordillera, targeting district-scale, underexplored mineralised systems.
“RM Research maintains a speculative buy on the back of the potential to outline high-grade copper-molybdenum at Lana Corina which we believe has potential for mineral resources of +80Mt (million tons) @ >0.80 percent CuEq (copper equivalent,” RM Research stated in its analyst report dated April 16, 2024.
Culpeo recently increased its ownership of Lana Corina to 50 percent, earning 80 percent to 100 percent. Recent drilling at Lana Corina showed copper-molybdenum mineralization over a strike length of 2 to 3 kilometres.
“The return of a drill rig to Lana Corina is imminent with extensions of breccia/porphyry hosted mineralisation being targeted as well as deeper copper and molybdenum associated with the silica cupola. Further surface geochemical results are also due this quarter from the La Florida Prospect,” the analyst report cited as near-term catalysts.
The Fotuna property is 10 kilometres north of Lana Corina, comprising three prospects along a 3-kilometre strike length. Results of recent drilling at Fortuna include 26 metres @ 0.81 percent copper equivalent, with elevated surface channel and rock chip samples up to 1.3 percent copper and 2.4 grams per ton gold.
Report highlights:
- Culpeo has increased its ownership of Lana Corina, where recent drilling returned impressive results of copper and molybdenum, over a 2 to 3 kilometre strike length. Near-term drilling will likely target extensions of the wide high-grade copper mineralisation hosted within the outcropping breccia pipes and associated porphyry intrusion.
- Achieving success in either the Lana Corina or Fortuna projects may lead to a rerating of Culpeo Minerals to more than $100 million market capitalization.
- RM Research maintains a speculative buy for Culpeo, driven by the potential to define the high-grade copper-molybdenum at Lana Corina, with a possible mineral resource of more than 80 million tons @ more than 0.80 percent copper equivalent.

UltraFine+TM Soil Sampling Programme
The survey was completed on a minimum spacing of 400m x 100m, with a total of 1,893 soil samples collected.
Figures 1 through 4 show the soil anomalies delineated from the sampling results. The five gold soil anomalies in Figure 1, represent areas with >50ppb Au – considered highly anomalous using this soil sampling technique. The largest gold anomaly is extends over 2km of strike and is located in a highly favourable structural setting. The copper and nickel anomalies are spatially adjacent to each other along with the high sulphur with a peak value of 5.33% and 50 samples >0.05% which would indicate the presence of weathered sulphides. Exploration reconnaissance and further geochemical sampling is planned to investigate the potential for magmatic sulphides and the presence of gossanous outcrop or subcrop.

Miramar Secures EIS Funding for Bangemall Ni-Cu-Co-PGE Drilling
Miramar has been advised by the Department of Energy, Mines, Industry Regulation and Safety (DEMIRS) that it has been awarded up to $180,000 towards the drilling campaign, which will target Norilsk-style nickel, copper, cobalt and platinum group element (Ni-Cu-Co-PGE) mineralisation at the Mount Vernon and Trouble Bore Projects for the first time (Figure 1).
Miramar is exploring for mafic intrusion-hosted Ni-Cu-Co-PGE sulphide mineralisation related to 1070Ma aged Kulkatharra Dolerite sills, part of the Warakurna Large Igneous Province and the same age as the large Nebo-Babel deposits in the West Musgraves.
Miramar’s Executive Chairman, Mr Allan Kelly, said the funding validated the Company’s exploration model and the potential district-scale opportunity within the Bangemall Project, and looked forward to the maiden drilling campaign.
“Over the last 24 months, the Company has advanced the Bangemall Projects from an exploration concept to regional-scale area selection followed by collection of project-scale datasets and, more recently, to delineation of individual drill targets through ground EM surveys,” Mr Kelly said.
“We have the opportunity to make a discovery of a new style of mineralisation in an underexplored geological province where we are the dominant landholder,” he added.
Upcoming work programme
Miramar’s initial aim is to show “proof of concept” of the Norilsk-style deposit model by discovering Ni-Cu- Co-PGE sulphide mineralisation.
- Upcoming work includes:
- Completion of heritage surveys where required
- Systematic rock chip sampling
- RC drilling
- Working towards grant of various tenement applications
Miramar already has Programme of Work (POW) approval for drilling at Mount Vernon and is currently waiting on approval for Trouble Bore.

Figure 2. Schematic diagram showing relationship between dolerite sills (green) and sedimentary units of the Edmund and Collier Basins, and the relative position of Miramar’s Ni-Cu-Co-PGE targets (red).
About the Ni-Cu-Co-PGE Bangemall Project
Miramar’s 100%-owned Bangemall Project comprises granted Exploration Licences and Applications covering approximately 2,190 km2 within the Gascoyne region of Western Australia.
The Proterozoic Edmund and Collier Basins have been intruded by numerous 1070Ma aged Kulkatharra Dolerite sills, part of the Warakurna Large Igneous Province, and the same age as the Giles Complex which hosts the large Nebo and Babel Ni-Cu deposits in the West Musgraves.
The region has been identified by both the Geological Survey of Western Australia and Geoscience Australia as having high prospectivity for Ni-Cu-PGE mineralisation associated with the Kulkatharra Dolerite sills, similar to the giant Norilsk-Talnakh Ni-Cu-PGE deposits in Russia.

Figure 1: Plan view of the Fortuna and Lana Corina Project areas
La Florida Prospect
The La Florida Prospect is a newly defined north-south trending belt of copper-gold mineralisation located within the northern sector of the Fortuna Project, measuring approximately 1.7km long by 0.5km wide (Figure 2). Mineralisation is hosted within andesitic volcanic rocks that have been intruded by quartz- feldspar porphyry lithologies. During the Quarter, a litho-geochemical survey was undertaken to characterise the nature and extent of the mineralised system. Rock chip samples were collected in areas including historic small scale mine workings, outcrop and subcrop on hills where bedrock/fresh rock was visible. All 14 rock chip samples returned anomalous copper and gold results, as shown in Appendix C.
The best copper result of 3.96% Cu was returned from CPO0008688, located in the northern part of the interpreted porphyry system where strong surface mineralisation was identified in the form of malachite and chrysocolla. This sample also returned a gold result of 1.17g/t Au. Of significance was CPO0008692, which returned high-grade copper and gold at 3.18% Cu and 2.61g/t Au1. The sample was taken from historical workings in fresh, unoxidised mineralisation.
