Bygoo Tin - EL 8260
Thomson has had early success in discovering a new tin deposit in the Ardlethan tin field at Bygoo North.
Thomson acquired EL8260 which surrounds the Ardlethan mine leases in a share deal early in 2015. Ardlethan is the biggest tin occurrence 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.
Two drilling rounds by Thomson in 2015 at Bygoo North, 7km north of the Ardlethan mine, have seen outstanding drill results and a better understanding of the geometry of these steeply dipping greisens. Best intercepts to date include 35m at 2.1% Sn from 44m (BNRC11), 10m at 2.0% from 108m (BNRC 13), and 13m at 1.0% Sn from 66m (BNRC 10). Drilling for a JORC resource is planned. Several other similar targets on the EL are also in line for testing.
The Ardlethan Granite is thought to be responsible for the tin mineralisation and its contact with the overlying rocks is fractured and mineralised at several different prospects north and south of Ardlethan Mine. These prospects include Bygoo North, as well as Big Bygoo, Lone Hand and Taylors Hill. All have shallow historic workings and the latter three have yet to be significantly drill tested with only a handful of holes drilled to date.
Thomson’s EL 8260 also includes a small part of the hard rock resource below and adjacent to the Ardlethan Mine Open-Cuts. Overall, EL 8260 has the potential to host a stand-alone tin project. This could be developed either separately or in tandem with a restart of the neighbouring Ardlethan Mine operation.
