Castillo Copper has delved into historical data for its Mount Oxide project, revealing intercepts of up to 28.4 per cent copper from a supergene ore body.

The review of data for the Big One deposit and Boomerang Mine within the project verifies they are highly prospective priority targets, the company says.

It has described the results as a game-changing development that enhance Mount Oxide’s exploration upside at the same time as a resurgence of interest in the region by large blue-chip groups including Rio Tinto.

“Locating this historic drilling, assay and production data for the Big One Deposit and Boomerang Mine within the 961km2 Mount Oxide pillar, which is in the heart of the Mount Isa copper-belt is a tremendous windfall,” Castillo Copper managing director Simon Paull said.

“As a starting point, our geology team now have ample data points to start formulating a drilling campaign to re-test and potentially expand the known ore body at the Big One deposit, then focus on Boomerang Mine and Arya Prospect. “

The Mount Oxide project is located 150km north of Mount Isa near the old Mount Oxide copper mine.
