Castillo Copper Ltd (ASX:CCZ) is shifting into top gear with exploration on its Zambian copper projects, one of three pillars the company is advancing in its strategy to become a mid-tier copper producer.
An in-country team is being deployed to the Mkushi project site to begin a comprehensive soil sampling campaign.
This will focus on previously identified structural targets, especially the 4-kilometre strike zone and ground contiguous to Shi & Yang Group’s (SYG) mining lease.
Samples to be gathered
The 100 by 500-metre grid will comprise 1,280 data points, across the southern half of the Mkushi project and should capture the NE-SW trending shear zones that extend out of SYG’s tenure.
This program is expected to take around 25 days to complete at a comparatively favourable cost with the samples to be bagged for follow-up analysis.
Castillo Copper’s managing director Simon Paull said: “As our in-country geology team can be deployed to site relatively fast and at a comparatively modest cost, the Board is now speeding up the exploration program across our Zambia pillar.”
Report highlights zones
The area being investigated in this campaign comprises some of the ground that SRK Exploration Services’ Independent Technical Report recommended focusing on, especially the shear zones and by implication 4-kilometre strike zone.
This report stated that artisanal miners had been active on these zones within SYG’s tenure.
“Following the recent site visit by SRK, we are now focused on conducting a broad soil sampling campaign that captures all high priority structural targets which should deliver a comprehensive understanding of copper mineralisation apparent at surface.
“Of particular interest will be the assay results along the 4-kilometre strike zone, which is part of the untested shear zone that originates in SYG’s mining lease.”
Underpin next phase
On receipt of assays, the geology team will have comprehensive insights into the copper mineralisation apparent at surface.
This will underpin the next phase of the exploration campaign which includes identifying potential drill targets.
With comparatively low costs in Zambia, the CCZ Board has decided to expedite the exploration campaign across the other four copper projects.
Luanshya to follow
A team is slated to go to the Luanshya project next to focus on the Lower Roan Group and NW-SW trendlines that intersect the tenure.
CCZ’s London-based director Ged Hall said: “Over the past few months, our confidence in the three pillars copper potential has continued to improve as the geology teams have ramped up desk-top and live exploration efforts to deliver more insights.
“In short, with the Zambia and Mt Oxide pillars located in regions with prime ‘copperbelts’ and Cangai being one of Australia’s highest grading historic copper mines, CCZ has three premium assets to develop ahead of listing on the London Stock Exchange.”
