Snapshot	The Red October underground mine is a complex high-grade gold deposit, which hosts several world-class and emerging gold mines. The mine has been under care and maintenance since 2021. Production has been suspended while the company is evaluating a potential whole-of-mine approach to exploration, development, and production options. During FY2024, the Company realigned its focus concerning the Red October. As a result of this realignment, the Company has begun a mining review of the Red October and evaluating further exploration opportunities. Consequently, as of 30 June 2024, the Red October is no longer considered an asset held for sale.

Deposit type

• Vein / narrow vein
• Breccia pipe / Stockwork

Summary:

Red October gold mine is situated within an Archaean greenstone belt of the Laverton Tectonic Zone. The stratigraphic sequence consists of footwall tholeiitic basalts, mineralised shale (containing ductile textures defined by pyrite mineralisation) and a hangingwall dominated by ultramafic flows interbedded with high-Mg basalts. Prehnite pumpellyite facies are evident within both the tholeiitic basalts and komatiite flows. Sulphide mineralisation is hypothesised to have been caused from interaction with an auriferous quartz vein, which has caused the intense pyrite-defined ductile textures of the shale in the upper levels. The fluid is believed to have been sourced from the intruding granitoid to the south of the deposit.

Mineralization at Red October occurs over 900m along strike and to a depth of 700m. Mineralization is hosted in vertical quartz breccia zones as well as where they intersect the primary host of graphitic black shales sitting on a Mafic/ultramafic contact. Inside the primary ore zone ore is seen as nuggetty visible gold and moving away from these zones mineralization is patchy with continuity along strike of between 5-20m and sub mineralization outside zones of silica flooding/brecciation.
