BINGARA

A soil sampling program within the Trevallyn prospect at Bingara was completed. This work involved surface and near surface sampling in the soils above the drainage of previously recovered indicator minerals and the 0.271 carat Trevallyn diamond (circa. 2002). Exploration conducted in the period was minimal, and involved sample prioritisation for future petrological micro probing to be conducted at a later stage. This will determine diamond indicator chemistry and set parameters for the next phase of work at Trevallyn, targeting additional “pipe like structures”. Depending on the results of the garnet chemistry at Trevalyn, an auger drill campaign to locate another potential pipe would follow at a later date.

Modest activities restricted to additional soil sampling, and petrological examination were conducted. The soil sampling programs have been successful in helping to isolate key diamond indicator mineral sources in the search for additional “pipe structures” within the diamond Project area at Bingara NSW.

The preliminary petrology report on rock chips and heavy minerals recovered from auger samples taken from Horton Valley No.2 Pipe at the Bingara project area confirmed earlier field observations made that a new discovery was made. The Trevallyn prospect was investigated through additional surface samples, mapping and limited auger drilling. An unusual rock type was discovered a likely xenocryst breccia up slope from the stream sediment diamond recovered in earlier exploration programs. Positive petrology results were received on Horton Valley No.2 Pipe auger drill samples and have confirmed earlier field observations. The petrology has indicated “very high garnet” yields (in excess of 100 grains per kg of raw auger cuttings) and the structure is a likely pipe. The geology does appear to be more complex at Horton Valley No.2, possibly reflecting a composite intrusion with local variation within the structure, or else several separate intrusions/breccia pipes/dykes. All 200 garnet grains that were micro-probed from the pipe were mantle derived.
