Develop Global Limited has issued an update on its Woodlawn Zinc-Copper Project in NSW.
Develop said drilling results indicate results of up to 10 per cent copper and 4.2 per cent zinc mineralisation outside the Underground Resource at the project.
According to the company, it is also making progress in relation to a potential production restart at Woodlawn, with a new life-of-mine plan to be released in mid-2023.
New progress on Woodlawn includes new updates on operational costs, the completion of the exploration drill drive, the creation of multiple-level accesses to the high-grade Kate lens and the completion of upgrades to critical underground infrastructures.
It added that additional metallurgical test work, including confirmation testing of a revised flowsheet, is underway to help determine performance targets as there is potential to increase recovery rates, which would, in turn, further boost the project’s economics.
In its update, Develop said approximately 40 per cent of the Woodlawn exploration and resource diamond drill program had been completed. It saw exceptionally high-grade copper and zinc mineralisation in the J lens area, significantly extending the known strike length and depth.
Additionally, mineralisation intersected in the C lens, significantly increasing the potential of the lens, which was previously thought to be closed off at depth.
“These results exceed even our expectations. The extremely high-grade nature of the intersections, particularly the copper, and the extent to which they extend the known mineralisation beyond the existing resource demonstrates the scope for significant growth in the inventory,” said Develop Managing Director Bill Beament.
He added that the company is also making progress in its preparations for a potential restart of production at the mine, saying underground development and upgrades to the site infrastructure and mine plan are proceeding well.
“With the metallurgical test work demonstrating potential for higher recovery rates and GR Engineering optimising the mill, we are meeting or exceeding every aspect of our plan to unlock the value of this outstanding asset,” Beament noted.
