Menzies is one of Western Australia’s major historic gold fields. Located 130km north of the globally significant gold deposits of Kalgoorlie.

The Menzies Gold Project or MGP covers a contiguous land package over a strike length in excess of 15km. Within the MGP a series of structurally controlled high-grade gold deposits have been historically mined and display extensive exploration potential for high-grade extensions. Modern exploration since closure over 20 years ago has been limited. The MGP is hosted along the Menzies Shear Zone.

All deposits lie within granted Mining Leases and are 100% owned by BTR.

The MGP has recorded historical production of 643,200 oz @ 22.5g/t Au1 from underground (U/G) between 1895 and 1943 plus 145,000 oz @ 2.6g/t Au1 open cut between 1995 and 1999, for a total of 787,200 oz @ 18.9g/t1 Au.

Production from Selkirk Profit Sharing JV

Brightstar has a 50:50 profit sharing JV with BML Ventures Pty Ltd to exploit the Selkirk deposit at Menzies (MRE of 11,500oz at 2.15g/t Au). BML Ventures is responsible for all capital costs, mining and haulage and the JV has a toll treating agreement with St Barbara Ltd (ASX: SBM) to process ore from Selkirk at Leonora, ~100km north of Menzies.

Geological Setting

The Menzies Gold Project is located along the western margin of the Menzies greenstone belt and, apart from the Lady Irene prospect, within a broad (2km – 5km wide) zone of intense ductile deformation often referred to as the Menzies Shear Zone. This broad highly deformed shear zone is probably the northern continuation of the Bardoc Tectonic Zone and is a major crustal feature of the Eastern Goldfields. The gold deposits within the MGP and those further south (e.g. at Goongarrie and Bardoc) have many similar characteristics. The Lady Irene prospect is west of the Menzies Shear Zone and thus within the Ora Banda domain, in a similar geological setting to the Sand Queen Gold Mine at Comet Vale, south of Menzies.
