News: Thomson Resources starts drilling at New South Wales tin project

Thomson Resources (ASX:TMZ) has started second phase drilling at its Bygoo tin project near Ardlethan, New South Wales, to test a new model of the tin-bearing greisen zones.

Ardlethan is the biggest tin deposit in NSW and is recorded to have produced 25,000 tonnes of tin in concentrate from open cut and underground operations between 1964 and 1986.

Bygoo North has similar geology to Ardlethan and limited drilling has shown good potential for an economic tin deposit.   

Inaugural drilling in June 2015 returned results including 13 metres at 1% tin from 66 metres (BNRC010); 5 metres at 1.3% tin from 130 metres (BNRC004) and 18 metres at 0.8% tin from 118 metres (BNRC003).

This confirmed the wide tin-bearing greisen zone intersected in 1977 drilling and discovered a previously unknown south dipping limb of the main lode, as well as a new greisen position in the footwall of the main zone.

While most of the Phase 2 holes are designed to confirm the new model centred on zones intersected in drill hole BNRC010, two additional holes are planned to test the virtually untested northern limb.

Final assay results expected by mid-October.

Bygoo drilling is being undertaken by shareholder Australian Mineral & Waterwell Drilling Pty Ltd who agreed to accept part payment for drilling services in TMZ shares.
