Ventnor Resources (ASX: VRX) has discovered a new high grade zone of strong bornite mineralisation central to the Thaduna prospect, which is part of the Thaduna/Green Dragon Copper Project in Western Australia.
The latest diamond drilling highlights reinforce the substantial exploration potential at the project, which is strategically located in the Doolgunna district - just 40 kilometres east of Sandfire Resources' (ASX: SFR) massive DeGrussa project.
High grade intersections include:
- 5 metres at 7.00% copper, including 2.7 metres at 11.72% copper and 29.7 g/t silver at a 5% copper cutoff;
- 9.5 metres at 4.40% copper;
- 10 metres at 3.26% copper;
- 4.6 metres at 5.83% copper;
- 2.5 metres at 7.36% copper;
- 13 metres at 3.57% copper;
- 5 metres at 4.94% copper;
- 6 metres at 4.78% copper; and
- 10 metres at 3.28% copper.
Importantly with the new high-grade discovery, the strong bornite mineralisation as the primary sulphide has resulted in higher copper grades.
Bruce Maluish, managing director, commented: "The significance of the increasing presence of primary bornite, compared to primary chalcopyrite, lies in the increase in relative copper by weight %.
"Chalcopyrite, CuFe2+S2, is 34.6% Cu compared with Bornite, Cu5Fe2+S4, is 63.3% Cu, an increase of 183% in Cu for the same mass of sulphide."
