Middle Island Resources unearths more high-grade gold at Sandstone

At the Ridge target, Middle Island Resources has hit 4m at 99.5g/t gold, including 1m at 390g/t gold.

Middle Island Resources (ASX: MDI) has unearthed what it describes as a “very high-grade intercept” from initial drilling at the Ridge target within its wholly-owned Sandstone gold project in Western Australia’s central goldfields.

Phase two reverse circulation drilling at the project uncovered 4m at 99.5 grams per tonne gold, including 1m at 390g/t gold.

A duplicate assay of 1m at 502g/t gold was returned from this hole.

This result arises from the most northerly hole completed to date at the Ridge satellite prospect, which is north-east of Middle Island’s gold processing plant and on a permitted mining lease.

Ridge also adjoins the Shillington Gap target which will be drilled towards the end of the current campaign.

Middle Island noted the intersection is 40m from a hole drilled in the first campaign that produced 3m at 8.77g/t gold.

Assays from this latest drilling at Ridge are incomplete and Middle Island noted it wasn’t possible at this stage to establish the full significance of today’s announced intersection.

The phase two drilling program is designed to infill and extend on the first campaign with the objective of upgrading mineral resources to indicated status.

To-date, 9,000m of the program has been completed. All-up 13,800m of reverse circulation drilling has been planned, with a further 1,000m of diamond drilling to be undertaken which will advance the current feasibility study.

Advancing Sandstone

The phase one drilling program at Sandstone focused on open pit targets within 4km of the processing plant, with the majority of targets on existing mining leases.

This program comprised 172 holes for 13,400m.

In mid-April, Middle Island reported a five-fold increase to its Sandstone global resource which stands at 624,000 ounces of contained gold.

The upgrade included a 500,000oz inferred resource for the project’s Two Mile Hill deeps deposit.

Two Mill Hill comprises 480,000oz gold within the tonalite-hosted portion and 20,000oz within the banded iron formation.
