Professor Gregor Borg, an expert on sediment-hosted copper systems, who has worked both in the Central African Copperbelt and the European Kupferschiefer, recently visited site to review the exploration programs and drill core from Tsenken and Tiria-Shimpia. Professor Borg commented, “I have not seen many mineralized systems that extend 45 kilometres along a fault system as we see in the central part of Aurania’s Lost Cities Project. The change from copper-centric in the Tsenken area to zinc-rich in the Tiria-Shimpia target is consistent metal zoning that is evident in the Kupferschiefer. I came away from my second review of Aurania’s sedimentary copper exploration program as convinced as I was on my first visit that the red-bed basin is highly fertile and has very good potential for sediment-hosted copper. We optimized some of the concepts on the basis of the features that we saw in the drill core, and I have encouraged the exploration team to keep drilling.”
Five drill holes have been completed at Tsenken N1 and hole 6 is underway – the objective being to explore the same sedimentary layer in the Tsenken area that contains zinc-silver in the Tiria-Shimpia area as illustrated in Figure 1.
Geological Detail of Tsenken N1 Drilling
Five drill holes, for a total of 2,184 metres (“m”), have been drilled in the Tsenken N1 target area and hole 6 is underway. The sedimentary layers targeted in hole 6 have been elevated to within a few hundred metres of surface, as illustrated in Figure 2, by faults that are known to have provided pathways for the metal-bearing fluids.
Drill results received to date are not economically significant but do show a clear trend with contained copper increasing towards the east: drill hole TSN1-002 – the westernmost – having no copper, hole TSN1-001 having 0.23% over 1m and hole TSN1-003 – the easternmost – having two mineralized zones; the upper sedimentary layer with 1m at 0.47% copper and the lower with 0.15% copper over 2.6m. Observations from the drill core show that the fault system was active at the time of accumulation of the red-beds in the Tsenken area and field mapping and satellite imagery show that this fault system extends into the Tiria-Shimpia area where it is linked with zinc-silver mineralization.
Holes TSN1-004 and TSN1-005 were collared further north, closer to Tiria-Shimpia and results will be reported when available.
Drilling at Tiria-Shimpia
A second drill rig has completed the first hole at Tiria-Shimpia and the second scout drilling hole is underway.
Sample Analysis & Quality Assurance / Quality Control (“QAQC”)
Laboratories: The samples were prepared for analysis at MS Analytical (“MSA”) in Cuenca, Ecuador, and the analyses were done in Vancouver, Canada.
Sample preparation: The rock samples were jaw-crushed to 10 mesh (crushed material passes through a mesh with apertures of 2 millimetres (“mm”)), from which a one-kilogram sub-sample was taken. The sub-sample was crushed to a grain size of 0.075mm and a 200 gram (“g”) split was set aside for analysis.
Analytical procedure: Approximately 0.25g of rock pulp underwent four-acid digestion and analysis for 48 elements by ICP-MS. For the over-limit samples, those that had a grade of greater than 1% copper, zinc and lead, and 100g/t silver, 0.4 grams of pulp underwent digestion in four acids and the resulting liquid was diluted and analyzed by ICP-MS.
QAQC: Aurania personnel inserted a certified standard pulp sample, alternating with a field blank, at approximate 20 sample intervals in all sample batches. Aurania’s analysis of results from its independent QAQC samples showed the batches reported on above, lie within acceptable limits. In addition, the labs reported that the analyses had passed their internal QAQC tests.
