Castillo Copper Limited (ASX: CCZ) has identified a potentially 6km long target during recently completed infill soil geochemical sampling campaign at the Luanshya Project in Zambia.
Managing Director, Simon Paull, saidthe encouraging infill campaign was conducted to reduce the sample and line spacing in the anomalous area identified by the previous sampling program in April 2020.
Using a portable XRF device, the team collected 765 soil samples from across the Luanshya Project with copper in soil anomalies up to 2,600ppm Cu defined.
Mr Paull said that consequently, the geology team were able to clearly demarcate sharp boundaries that contains anomalous copper mineralisation over an extensive circa 6km strike even
Notably, the infill results from the Luanshya Project clearly underscore the potential exploration upside along the circa 6km strike,” Mr Paull said.
“The geology team’s objective is to systematically complete trenching and geophysical work then formulate priority targets to test-drill.”
To further test the identified copper mineralisation along strike, the geology team are shortly planning to dig five trenches with a total length of circa 1,500m to garner incremental insights.
Once the results of the trenching programme are reviewed, the next phase will be an induced polarisation survey to identify geophysical anomalies at depth.
Mr Paull said that post the IP survey, the Zambia geology team will be able to reconcile the results of the geochemical and geophysical data then commence formulating an inaugural drilling campaign to test key targets.
The Luanshya Project is located in Zambia’s traditional copper-belt which is well known for numerous large-scale copper mines and deposits.
Previous desktop work by CCZ’s in-country geology team highlighted four regional trendlines, circa 5-10km wide in places, running NW-SE that are known to host copper mineralisation.
Mr Paull said it is now confirmed the anomalous area and two of CNMC’s three operating copper mines are on the same trendline that intersects the Luanshya Project.
