Castillo Copper Ltd is set to launch a comprehensive induced polarisation (IP) survey across the key Luanshya and Mkushi projects in Zambia’s copper-belt.
Managing director Simon Paull made the announcement and said that the process will take 6-8 weeks to complete and fully analyse the results.
To accelerate identifying targets that can be drill tested, the company explorer has engaged Geophex Surveys (GS) to undertake the survey. Reconciling findings with known anomalous areas at surface should identify priority targets to drill.
“Having already completed soil sampling campaigns that have delineated anomalous areas across the Luanshya and Mkushi projects, undertaking comprehensive IP surveys will potentially facilitate identifying targets to test drill. Overall, the board looks forward to receiving the geophysicists interpretations, as the Luanshya and Mkushi projects deliver significant exploration potential,” said director Simon.
The Luanshya Project is 6-10 kilometres south of China Nonferrous Mining Corp’s (CNMC) three operating mines, with a combined JORC (2012) proven and probable reserves of 52.3 million tonnes at 1.26% copper. Further, across the region are four northwest-southeast trendlines, which are around 5-10 kilometres wide, that host numerous historic and current operating mines and deposits. At Mkushi, two parallel northweast-southwest shear zones originate in Shi Yan Group’s (SYG) contiguous mining lease.
The operating Mushiwemba Copper Mine is within the north shear zone and constrained within SYG’s ground. However, the south shear zone, which comprises similar geological structures, trends into the Mkushi Project and is a clear target area.
The soil sampling campaign highlighted five, well-defined, anomalous areas with respective strike lengths ranging from 2-7 kilometres. Given these anomalous zones are close to the shear zone, they are likely part of the same over-riding system.
