E79 Gold Limited (ASX: E79) has sharpened the Mountain Home Copper–Gold (Figure 1) story in the NT with a simple but telling update (23 October 2025): fresh mapping plus 24 rock-chip samples have pushed high-grade copper outside the known gossan and onto parallel trends. With assays up to 35.9% Cu and Cu-Au-Bi mineralisation tracking along sinistral brittle faults, the footprint now looks more like a structural corridor than a single showing.
