Drill results from the Happy Jack and East Lode areas have added further evidence that Wiluna’s namesake mine is a very large and high-grade ore body.

Notable results include 8.2m grading 6.28 grams per tonne (g/t) gold and 23.16g/t gold (WURD0169), 5.7m at 5.98g/t gold, 3m at 5.12g/t gold and 13.2m at 7.41g/t gold (WUDD0075), and 7.75m at 13.27g/t gold (WURD0207).

The drill results from the resource development drilling at Happy Jack and East Lode, both initial mining areas in Wiluna Mining’s (ASX:WMC) two-staged development plan, continued the consistent delivery of thick, high-grade intercepts over the past 18 months at the mine.

At Happy Jack, ore drive development on sulphide mineralisation is underway ahead of stoping this quarter.

Infill drilling is ongoing with a focus on resource infill, resource extension and grade control programs at the Bulletin and Happy Jack ore bodies.

A mineral resource update to the current resource of 26.9 million tonnes grading 4.9g/t gold remains on track for release this month while feasibility study and ore reserves are expected in the March quarter 2022.

The company believes that with drill results like these, it is likely that that mined grade will increase when stoping commences.

Resource and ore reserve upgrades will also support the company’s goal of achieving gold production of 120,000oz per annum by the end of the 2022 financial year.


Drill results

Wiluna’s drill program was designed primarily to infill areas of inferred resource within preliminary stope designs, with the aim to upgrade geological confidence to the higher confidence indicated category and to grow the ore reserve.

Additionally, extensional drilling has aimed to extend potential stoping areas along strike, up-dip and down-dip.

This will provide the foundation for a sustained long-term mining operation.

In addition, drilling at Happy Jack also shows potential for resource growth where holes have intersected the mineralised shear zone outside of the current resource limits.

The company’s drilling to date has focussed on the upper 300m down to 500m below surface, and considerable potential for resource extensions exists where the lodes remain open at depth and along strike.

At East Lode, drilling has demonstrated that significant high-tenor mineralisation remains in situ over broad areas surrounding historically mined areas.
