Middle Island Resources Limited (ASX: MDI) has updated resource estimates for the Shillington (including Shillington North) and Wirraminna gold deposits within the company’s wholly-owned Sandstone gold project in the central goldfields of WA.
A 27,800oz (or 52%) increase in the gold resource to 80,700oz has been derived for the Shillington deposit, while a proportion of the Shillington deposit classified as an Indicated Mineral Resource also increased by 7,200oz (or 17%).
The updated estimates follow completion of limited infill and extension drilling undertaken as part of the +30,000m 2020 exploration and resource definition drilling campaign at Sandstone.
Managing Director, Rick Yeates, said the drilling, which is on-going, is exclusively focussed on the definition of additional open pit Mineral Resources prior to their inclusion for assessment as Ore Reserves in the project’s 2020 feasibility study (FS).
An increase of 27,800oz (or 52%) at the Shillington deposit is an extremely pleasing start in the Company’s plan to increase open pit Mineral Resources contributing to the FS,” Mr Yeates said.
“Limited additional RC and diamond drilling is planned at Shillington to address two small areas still classified as Inferred that are anticipated to fall within the optimum FS pit.
“The updated Shillington and Wirraminna open pit deposits will now be re-optimised to determine the Mineral Resource likely to contribute to the FS, the outcome of which is looking increasingly positive.
“The Two Mile Hill open pit Mineral Resource is in the process of being updated, and we look forward to providing that information in the very near future. Resource estimates for all remaining deposits (old and new) will be progressively provided as results from the Phase 2 drilling campaign are received and compiled.”
