Cobre Limited Confirms High-Grade Copper Continuity at Cosmos Target
Cobre Limited (ASX: CBE) has delivered promising early results from its ongoing drill programme at the Cosmos Target within the wholly-owned Ngami Copper Project in Botswana. Visual mineralisation estimates, supported by portable X-ray fluorescence (pXRF) analysis, have revealed significant chalcocite mineralisation in drill hole NCP68, located 400 metres along strike from the previously successful NCP55 intersection.
The results provide strong encouragement for a laterally extensive higher-grade copper-silver zone spanning more than 400 metres at Cosmos. Furthermore, this development shows potential for both In-Situ Copper Recovery (ISCR) and conventional underground mining operations within the Cobre Ltd copper project in Botswana.
Key Highlights Drive Expanded Programme
The early results have generated sufficient confidence for Cobre to expand the original drill programme. Based on the encouraging preliminary findings, two additional infill diamond drill holes have been added, strategically positioned on either side of the successful NCP55 to further test grade continuity and variability.
Moreover, the key performance indicators demonstrate significant progress:
- NCP68: Notable vein, fracture and cleavage hosted chalcocite mineralisation logged over 6 metres from 198-204m downhole (approximately 4m true width)
- Strike continuity: Evidence of higher-grade zones extending over 400+ metres
- Strategic positioning: Cosmos located 8km along strike from the established Comet Deposit
"This is a great start to the Cosmos drill programme with early results confirming the higher background copper grades at this extensive target. The next two drill holes will provide important indicators of grade continuity and variability which will guide our follow-up programme," commented Adam Wooldridge, CEO.
Understanding Chalcocite Mineralisation
Chalcocite is a copper sulfide mineral (Cuâ‚‚S) that typically contains around 80% copper by weight, making it one of the most valuable copper minerals. Unlike other copper minerals, chalcocite is particularly amenable to acid leaching processes, which makes it ideal for In-Situ Copper Recovery (ISCR) operations.
Consequently, this discovery holds significant value for investors. Chalcocite's high copper content and leaching characteristics mean it can be economically extracted using lower-cost ISCR methods, potentially delivering superior project economics compared to traditional mining approaches.
The mineral's occurrence along fracture zones and cleavage planes at Cosmos creates the ideal geological conditions for ISCR implementation. This technical advantage positions the Cobre Ltd copper project in Botswana as a potentially low-cost copper producer.
Strategic Context Within Ngami Copper Project
The Cosmos Target represents a significant component of the broader NCP Exploration Target, estimated at 205-308 million tonnes grading 0.31-0.46% copper and 5.5-8.3 g/t silver. This substantial resource base positions Cosmos within a world-class copper district.
In addition, the comparison with established ISCR projects demonstrates remarkable scale potential:
| Project | Company | Resource | Grade | Location |
|---|---|---|---|---|
| Florence Copper | Taseko Mines | 320Mt | 0.36% Cu | Arizona |
| Van Dyke | Copper Fox | 265.6Mt | 0.29% Cu | Arizona |
| Ngami (Target) | Cobre | 205-308Mt | 0.31-0.46% Cu | Botswana |
The comparison with established ISCR projects in Arizona demonstrates the scale potential of Ngami. These similar tonnage and grade characteristics have proven commercially viable using ISCR methodology.
Drilling Programme Details and Technical Results
The expanded Cosmos drill programme now includes four diamond holes totalling approximately 1,000 metres. These holes are designed to assess strike continuity on 400-metre step-outs, providing comprehensive coverage of the higher-grade zone identified in the breakthrough NCP55 intersection.
The current drilling status shows systematic progress:
| Hole ID | Status | Depth (m) | Location Relative to NCP55 | Key Results |
|---|---|---|---|---|
| NCP67 | Complete | 239.5 | Northeast | Average copper grades |
| NCP68 | Complete | 245.7 | 400m Southwest | Significant chalcocite zone |
| NCP69 | In progress | ~250 | Infill position | Pending |
| NCP70 | Planned | ~250 | Infill position | Planned |
NCP68 Mineralisation Results
The NCP68 results demonstrate exceptional mineralisation characteristics:
- Primary zone: 198.56-205.9m downhole
- Peak interval: 199.75-199.86m with 7% visual chalcocite abundance
- Mineralisation style: Vein, fracture, and foliation-hosted chalcocite
- pXRF validation: Spot measurements confirm visual estimates
ISCR Potential and Economic Advantages
The geological characteristics observed at Cosmos align perfectly with successful ISCR operations globally. The fine-grained chalcocite mineralisation occurs along well-developed fracture zones with competent hanging and footwall units.
These conditions represent exactly what's required for effective in-situ leaching. Additionally, ISCR offers numerous advantages for the Cobre Ltd copper project in Botswana:
- Lower capital requirements compared to conventional mining
- Reduced environmental footprint with minimal surface disturbance
- Faster development timeline to production
- Lower operating costs through elimination of mining and milling
- Extended mine life potential through enhanced recovery techniques
Furthermore, the chalcocite mineralisation's occurrence below the water table and its acid-leaching amenability enhance the ISCR potential at Cosmos. These technical advantages position Cobre as a potentially low-cost copper producer.
