Marquee has completed five diamond drill holes - one from the Old Mine Zone and four from the West Cobalt target area in order to collect about 150 kilograms of material for metallurgical testing of the mineralisation at Werner Lake.
The drill cores have been logged and sampled. Core samples have been shipped for analysis and once results have been received, a composite sample will be created and shipped to SGS Canada’s Lakefield facility for study.
A head sample will be selected and submitted for cobalt, copper, iron and arsenic analysis.
Metallurgical work will include:
• Batch flotation testing to identify appropriate conditions for subsequent bulk flotation testing to produce cobalt concentrate;
• batch POX testing to establish conditions for the extraction of cobalt from bulk concentrates;
• bulk batch POX testing to produce cobalt PLS for downstream testing; and
• bench scale solution treatment to evaluate potential cobalt and copper products.
The testing program is expected to take three months to complete once the lab has received the sample and is a critical next step when assessing potential off take arrangements with end users.
Marquee’s phase two drill program is ongoing and the company has now completed 15 holes at the project.
Marquee expects to report the results from the rest of this phase 2 drilling campaign shortly.
