Kamilombe Project High Grade Drill Intersections
Borders on KCC’s Mashamba deposit (40,000 tonnes of contained Cobalt)
- Cobalt mineralisation defined over 1km strike length, open at depth
- Significant Cobalt drilling results included 50.87m at 0.49% Co from 5.8m including 13.68m at 1.21% Co from 30.47m; 31.21m at 0.52% Co from 33.1m including 3.04m at 1.45% Co from 36.4m and 5.18m at 1.05% Co from 57.7m
- Best copper result included 24.5m at 1.22% Cu from 138.3m
- Mineralisation within typical Mines (R2) Series stratigraphic units
- Drilling intersected multiple mineralised zones which were duplicated through thrusting and folding
- Metallurgical samples submitted to test viability of early shallow production
The Company twinned 5 historic holes drilled by La Générale des Carrières et des Mines (Gécamines) and KCC on a 200m x 200m grid at Kamilombe as no information with respect to aggregation methods, methods of analysis, QA/QC and recoveries was made available. Samples collected from artisanal pits at depths ranging between 25m and 75m below surface reported grades of 0.98% Co to 6.49% Co further confirming the potential for Kamilombe.
Taruga’s drilling results support the potential for Kamilombe to host substantial Cobalt mineralisation from surface and Copper mineralisation at deeper levels.
Cobalt mineralisation was intersected in all diamond drill holes which reported best results of:
- 50.87m at 0.49% Co from 5.8m including 13.68m at 1.21% Co from 30.47m and 8.85m at 0.41% Co from 88.85m in KMDD005
- 31.21m at 0.52% Co from 33.1m including 3.04m at 1.45% Co from 36.4m and 5.18m at 1.05% Co from 57.7m in KMDD001
- 10.72m 0.38% Co from 40m in KMDD004
Significant Copper intersections included:
- 16.16m at 1.05% Cu from 72.3m and 24.5m at 1.22% Cu from 138.3m in KMDD001
- 8.85m at 1.32% Cu from 88.85m in KMDD005
Drilling has confirmed mineralisation over a minimum of 1km strike length. All mineralisation is confined to the Mines (R2) Series where thrusting and folding has duplicated a number of mineralised units at deeper levels. Thicknesses of the mineralised intersections are close to true thickness as shown in section in Figures 3 and 4 except when adjacent to thrust faults where they tend to steepen.
A series of representative metallurgical samples for the mineralised stratigraphic units at Kamilombe were submitted to ALS Global in Perth for metallurgical studies. The Company considers that simple treatment, such as HMS (Heavy Media Separation) and or gravity separation, will concentrate the shallow Cobalt mineralised material on strike to that identified in KMDD005. Drill samples indicate the ore is friable and may not need crushing or particle size reduction, simplifying the concentration plant requirements. Artisanal miners presently use simple hand operational methods, without chemicals, to produce a saleable concentrate, which suggests a commercial operation could be deployed to achieve more consistent results from controlled processing equipment.
Taruga plans to start early, shallow surface mining on completion of the metallurgical studies through simple concentration processes once confirmed.
The Company will drill the area with potential for near surface mineralisation as a priority on the successful completion of the ongoing Due Diligence at Kamilombe. This will give a better understanding of potential grade and nature of the material available for a small treatment plant. Taruga will also conduct an infill drilling programme over the most prospective area at Kamilombe for early resource definition.
1NOTE: All samples were prepped at ALS Global’s sample prep facility in Lubumbashi from where pulps were submitted to ALS Global’s accredited laboratory in Johannesburg for 4 acid digest and ICP-AES finish. Reported results used a cut-off grade of 0.5% Cu and 0.1% Co with a maximum dilution of 3m within each intercept.
2NOTE: A diamond drilling programme was carried out by KCC Katanga and Gecamines which ended in 2013 at the Kamilombe project. Diamond drilling was vertical and referred to down hole intersections, true width not known. Cautionary Statement: No detailed information regarding logging, core recoveries, surveys, QAQC was provided, and the Exploration Results were not reported in accordance with the JORC Code 2012 or made publicly available. The Company twinned 5 of these holes during the ongoing due diligence period to confirm the current model, grades and widths and true thickness of mineralisation reported by Gecamines/KCC Katanga. A poor correlation between prior reported exploration results and Taruga’s drilling results have confirmed that prior results may not be reported under the JORC Code 2012.
