Drilling at Shaw River Manganese Ltd’s Baramine project in Western Australia’s Pilbara region has returned a host of highly promising results with grades of up to 46% manganese.

The latest intersections originate from Shaw River’s recently completed 10,000 metre RC drilling program at Baramine, which is 70km north of the producing Woodie Woodie manganese mine and 270km East of Port Hedland, one of the world’s largest bulk port facilities.

The results highlight Baramine’s strong potential and Shaw River intends to proceed with resource estimation, drilling and beneficiation test work. The drilling followed up earlier encouraging drilling results which identified a prominent corridor of manganese mineralisation known as the Area 3-Area 4 corridor.

The latest assay results include two intersections of 46%, the highest achieved at the project to date.

The identification of a coherent zone of manganese at Area 3 includes potentially economic material such as 10 metres @ 31% manganese and 28 metres @ 20%. One hole in Area 3, drilled to a depth of 152 metres, contained an average of 10% manganese over its entire length from surface. Area 4 intersections in the current program include 10 metres @ 19%, 6 metres @ 18% and individual 1 metre intersections with grades of up to 35%.

Earlier beneficiation test work using DMS (Dense Media Separation) indicated the ability of 20% feed material from Baramine being able to produce a concentrate grading of 43% manganese and 10% iron.

Exploration at Baramine has previously identified widespread manganese occurrences in a similar setting to elsewhere in the East Pilbara Manganese province. These occur at the interface between the Carawine Dolomite and the Pinjian Chert Breccia with more intense and larger scale mineralization occurring along fault structures. At Baramine, such a zone of intense manganese mineralization was identified through rock chip sampling, soil sampling, mapping and drilling. This zone extends over a distance of 4km from Area 3 in the north to Area 4 in the south with an average width of alteration across strike of 150 m.

Following the success of the current program, follow up drill programs including diamond drilling for beneficiation test work are being planned to infill and extend the discoveries at Area 3-Area 4.
