Aeris Resources Ltd (ASX:AIS) has been working on an updated mineral resource estimate (MRE) for the Turbo lens at Bentley deposit within the 100%-owned Jaguar Operations in WA and the results are in.
Resource definition drilling continued throughout the first half of 2022, focused on expanding the mineralised footprint and upgrading the mineral resource classification to indicated status.
The updated MRE is based on the inclusion of an additional 37 additional drill holes used to update the geological interpretation and increase the confidence in the grade estimates.
Sizeable increase
The company’s updated MRE boasts 1.26 million tonnes at 1.82% copper, 8.5% zinc, 0.72 g/t gold and 47 g/t silver. This represents an increase on its December 2021 MRE as follows:
- 23% increase in tonnage;
- 39% increase in contained zinc metal;
- 17% increase in contained copper metal;
- 21% increase in contained gold metal; and
- 53% increase in contained silver metal.
Indicated status
The majority of the resource classification – 89% by tonnage – has been upgraded to the indicated status.
The Turbo lens remains open along strike and down plunge and highly prospective for further extensions.
What’s more, recent drilling has intersected massive sulphides outside the mineral resource footprint:
Aeris executive chairman Andre Labuschagne said “The updated mineral resource has materially increased the ore tonnes and metal content at the Turbo lens.
“This drilling campaign has also resulted in the majority of the mineral resource being upgraded to Indicated status.
Further resource increases likely
“We believe there is strong potential for further mineral resource increases at Turbo, as it remains open along strike and down plunge.
“This view is supported by recent drilling outside of the resource envelope, which has intersected massive sulphide mineralisation.”
