I'm hoping that, at depth, Four Eagles hosts similar ore bodies to the nearby Fosterville mine (highest grade gold mine in Aus).

Firstly, note Bruce Kay's observation at the end of yesterday's ann with regards to the six (as yet un-assayed) deeper DD cores: "Six diamond drill holes were completed on the Boyd’s dam trend as shown on Figure 4 and another 7 holes at Hayanmi. The Boyd’s Dam holes intersected broad zones of quartz with arsenopyrite and some visible gold."

I am a self-confessed geology ignoramus but I'm sure that Bruce Kay (former Head of Worldwide Exploration for Newmont) knows a thing or two about gold exploration. Compare Bruce Kay's observation above to the extract below which is from the Kirkland Lake website and is their own summary of the Fosterville geology (including the ultra-high-grade Swan zone). Note specifically the references to arsenopyrite and visible gold which are common to both texts.

"Fosterville Geology & Mineralization

The Fosterville Goldfield is located within the Bendigo Structural Zone in the Lachlan Fold Belt. The deposit is hosted by an interbedded turbidite sequence of sandstones, siltstones and shales. This sequence has been metamorphosed to sub-greenschist facies and folded into a set of upright, open to closed folds.

Mineralization at Fosterville is controlled by late brittle faulting. These late brittle faults are generally steeply west dipping reverse faults with a series of moderately west dipping reverse splay faults formed in the footwall of the main fault. There are also moderately east dipping faults which have become more significant footwall to the anticlinal offsets along the west dipping faults. Primary gold mineralization occurs as disseminated arsenopyrite and pyrite forming as a selvage to veins in a quartz–carbonate veinlet stockwork. The mineralization is structurally controlled with high-grade zones localized by the geometric relationship between bedding and faulting. Mineralized shoots are typically 4m to 15m thick, 50m to 150m up/down dip and 300m to 1,500m+ down plunge, and have average grades of 5 10 g/t Au, with individual assays up to 60 g/t Au.

Primary gold also occurs as visible gold at Fosterville, where it variably overprints sulphide mineralization, and is found as disseminated fine specks (>1 mm) of gold within host quartz veins. The visible gold is spatially associated with antimony mineralization, in the form of stibnite that occurs with quartz and varies from replacement and infill of earlier quartz-carbonate stockwork veins, to massive stibnite-only veins of up to 0.5m in width. The stibnite-quartz event occurs in favorable structural locations, such as the Phoenix, Eagle and Lower Phoenix structures.

The occurrence of visible gold is becoming increasingly significant at depth and is observed more frequently below an approximate 800m with depth, down-plunge within the Lower Phoenix and Harrier Gold Systems.

Examples of the visible high-grade gold zones include the Eagle and Swan Zones in the Lower Phoenix area. The Eagle Zone is 0.5 6m in width, 50 80m in dip length and has a down-plunge extent of 700m. The Swan Zone, currently the highest grade mineralized zone at Fosterville, is 2-5m in width, dips west and is presently defined over a 275m strike and a 200m vertical extent. The Eagle and Swan Zones remain open down-plunge for potential Mineral Resource expansion."
