Castillo Copper confirms copper target at Luanshya Project

Global Mining Review,

Castillo Copper Ltd, a base metal explorer primarily focused on copper across Australia and Zambia, has announced encouraging results from the recently completed infill soil geochemical sampling campaign at its 100% owned Luanshya Project in Zambia.

The Luanshya Project is located in Zambia’s traditional copper-belt, the second largest copper producer in Africa. It is intersected by a NW-SE trend-line, that is approximately 5 – 10 km wide in places and known to host copper mineralisation. This includes two of China Nonferrous Mining Corp.’s (CNMC) three operating copper mines that are approximately 7 km north-west of the anomaly and bear similar geological features to Luanshya. The infill campaign was conducted to reduce the sample and line spacing in the anomalous area identified by the previous sampling programme in April 2020.


  • Castillo’s Zambian geology team has completed a comprehensive infill surface sampling campaign at the highly prospective Luanshya Project which has delivered encouraging results:
    • Ratification that a high-priority target for copper mineralisation, along a circa 6 km strike event, is apparent.
    • Building on the first campaign, undertaken in April 2020, the geology team properly demarcated the anomalous area which highlighted portable X-ray fluorescence (XRF) results up to 2600 ppm Cu.

Next steps for Zambia

The next two phases of the exploration campaign – that will be progressed sequentially – are designed to narrow down key test-drill targets. They include:

  • Digging five trenches, with a total length of circa 1500 m, to test the copper mineralisation identified.
  • An induced polarisation (IP) survey to identify geophysical anomalies at depth which correlate with the surface geochemical results.

Concurrently, members of the geology team have been undertaking an infill soil campaign at the Mkushi Project – findings are expected to be released shortly.

Simon Paull, Managing Director of Castillo Copper, commented: “It is pleasing to be able confirm that Castillo now has geology teams undertaking excellent work in Zambia and north-west Queensland. Notably, the infill results from the Luanshya Project clearly underscore the potential exploration upside along the circa 6 km strike. The geology team’s objective is to systematically complete trenching and geophysical work, then formulate priority targets to test-drill.”

Ged Hall, UK Director of Castillo Copper, said: “The work undertaken by our geology team in Zambia has delivered a compelling initial outcome, with a circa 6 km copper strike to explore. This is the start of an exciting journey which is unfolding to the upside.”
