Multiple Significant Intercepts In Ongoing Drilling Campaign
Wiluna Mining Corporation Limited (ASX: WMX) has achievedfurther high-grade results from an additional 32 holes and 8,127m of resource development and discovery drilling at the Wiluna Mining Centre in Western Australia
The company has reported multiple significant intercepts from 56 holes and 7,525m of previously un-sampled mineralisation identified in the large historical core library at the Wiluna mine site.
The ongoing drilling success is part of resource and reserve development programnes at the Wiluna Mining Centre which are designed to follow-up positive drilling results reported through the past 12 months.
The drilling programme focuses on highest-value deposits scheduled for mining in the next four years to further strengthen the sulphide mine plan, with results reported here from Essex, Bulletin and West Lode South zones. The company has currently deployed seven rigs at the Wiluna operation with drilling accelerating in January 2021.
Wiluna Mining’s drilling strategy in the past 12 months has successfully defined thick high-grade intervals at shallow levels, close to multiple previously mined zones with available access for rapid low-cost development. These results demonstrate that the Wiluna orebody is a very large scale and high-grade gold system.
Drilling has recently focused on the Bulletin zone in the Wiluna North Mine area. The ongoing programme at Bulletin is designed to infill areas of Inferred resource within preliminary stope designs, with the aim to upgrade geological confidence to Indicated resource category, and to extend potential stoping areas along strike, up-dip and down-dip. Excellent results were achieved from this programme.
- 6.73m @ 5.56g/t from 50.27m
- 10.44m @ 3.29g/t from 54.90m including 4.00m @ 5.74g/t from 54.90m
- 11.00m @ 4.04g/t from 46.00m including 6.00m @ 5.80g/t from 48.00m
- 13.37m @ 7.03g/t from 68.00m
- 3.64m @ 9.93g/t from 42.36m
- 5.45m @ 4.76g/t from 309.00m including 3.91m @ 5.48g/t from 310.54m
- 5.00m @ 3.99g/t from 357.00m
- 7.90m @ 6.21g/t from 349.10m, within broad mineralised halo of 16.70m @ 3.84g/t
An ongoing programme at Essex, which is a high-grade, high-priority mining zone in the Wiluna Central Mine area, continues to generate excellent results. Drilling is designed extend potential stoping areas both up-dip and down-dip.
Drillinng intersected visible gold mineralisation, which is reflected in the ultra-high-grade assay of 0.45m @ 57.30g/t, within a broader zone of 4.05m @ 9.20g/tlocated down-dip from the preliminary stope designs).
The results are considered highly significant because the occurrence of very high-grade sulphides with visible gold is 50m below Wiluna Mining’s previous deepest high-grade drillholes (8.00m @ 5.31g/t & 8.00m @ 15.20g/t.
Meanwhile, a programme at West Lode South, which is a high-priority target in the Wiluna South Mine Area, continues to generate excellent results. West Lode South is targeted owing to its location adjacent to the East Lode South resource area and existing decline access, with potential to add to mine life and improve the head grade based on the thick high-grade mineralisation intersected in the current program and Wiluna Mining’s previous holes.
West Lode was historically mined via underground between 1932 and 1946 and produced 691,000oz @ 8.6g/t, which demonstrates the scale and high-grade nature of this target zone. West Lode remains open and sparsely drilled to the south, with potential to delineate resource extensions and to make a new shoot discovery.
