Snapshot	The combination of the current Edna May underground resource and the Edna May Stage 3 open pit Scoping Study mining inventory represents a potentially significant life extension for the Edna May production center. But the Board determined that the economic case for the project was not strong enough to justify investment required. Heightened technical risk added to the reluctance to move ahead at this time. As of December 2023, Pre-Feasibility Study work was completed, but the project was deferred due to market volatility.

Deposit type

• Metamorphic hosted
• Breccia pipe / Stockwork
• Vein / narrow vein

Summary:

The deposit is well understood geologically. The Edna May Gneiss (EMG) is a metamorphosed tonalitic granitoid within a mafic-ultramafic stratigraphy. It hosts the gold mineralisation which occurs as sheeted quartz, minor sulphide veining, generally parallel to strike and less frequent larger quartz lodes/reefs which cross-cut the gneiss with a more northerly strike and westerly dip. The gneiss strikes east-west (100-120°) and dips at 50-60° to the north. It has a strike length of 1,000m, a width of 50–150m and depth extent of at least 700m. Significant background Au anomalism (0.1 - 0.5 g/t) is present, associated with alteration intensity, proximity to veining and micro-fracturing. Visible gold is frequently seen in drill core in close association with veining and gravity recovery is very high for a low-grade deposit at around 50%.

Hosted by the Edna May Gneiss, a metamorphosed granitoid with strike length of 1km, width of 140m and depth extent of 700m and bounded by a maficultramafic stratigraphy. Mineralisation relates to widespread quartz veining, which occurs as thin sheeted foliation parallel or larger cross-cutting reef veins with a polymetallic sulphide assemblage. Mineralisation forms a broad low-grade stockwork throughout the gneiss. Greenfinch deposit very similar.

Dimensions
Edna May gneiss unit is a lenticular body, typically 50-150m thick, 1000m long and defined down-dip to 700m. It strikes east-west and dips N at 50-60°. Internal high-grade quartz reefs occur and strike N-NE and dip 45-50 W. These are generally 100m in length and 2-4m wide.
