Coda Minerals Flotation Testing Delivers Pathway to Improved Recoveries

THE DRILL SERGEANT: Coda Minerals (ASX: COD) reported encouraging initial results from ongoing metallurgical test work it is conducting on material sourced from the company’s 100 per cent-owned Elizabeth Creek copper-cobalt project in South Australia.

Coda Minerals is conducting the test work on the back of a positive Scoping Study, delivered in March 2024.

The latest results relate to recently completed metallurgical test work on material from Windabout, one of the open pit deposits at Elizabeth Creek where a series of flotation tests assessed the impact of novel oxide collectors (Syensquo Aero® Ox 100 series and 3418A) on copper recovery.

Both sets of tests improved recoveries of both copper and cobalt.

“To deliver a transformational uplift at Elizabeth Creek we have two major levers to pull: the first is in exploring for additional Resources and the second is in seeking to increase copper recoveries,” Coda Minerals CEO Chris Stevens said in the company’s ASX announcement.

“This work is the first step in achieving improvements to recoveries by delivering a major uplift during the rougher float stages without incurring any significant additional costs.

“Pursuing an Increase in recovery numbers is extremely important as it essentially delivers more payable metal from the same number of mined tonnes without a material increase in costs.

“We have commenced test work with Windabout, which has the lowest overall recoveries across the project, but we anticipate that this change in flotation collectors will also deliver major improvements for the MG14 and Emmie Bluff deposits.

“These tests show that this work has been extremely worthwhile, demonstrating unequivocally that the right combination of reagents can concentrate the oxides within these deposits.

“With this successful application during the rougher stage, we will now progress to test work across the whole flotation process through to cleaner concentrate.

“Following that we will then undertake test work on MG14 and Emmie Bluff as well.

“Once complete, we anticipate that this work will give us updated recovery numbers for each deposit, flowing through ultimately to a potentially significant boost to overall project economics.”
