Avoca Resources Limited (AVO) –Bringing Trident Into Production
- After acquiring Higginsville from Gold Fields in 2004, Avoca has discovered a new orebody called Trident, comprised of two steeply dipping mineralised zones immediately north of the old Poseidon South open-cut and underground workings (which contained near vertical and shallow dipping mineralised gold lodes of ore).
- The two near vertical zones designated Eastern and Western appear to each contain at least 3 significant (5g/t to 20g/t) gold veins, which may be amenable to a combination of bulk and narrow vein mining with treatment through a gravity plant due to the extremely high gravity recoveries averaging 86% (total recovery ~97%).
- In its latest announcement on 27 April 2005, Avoca reported its latest assay results indicating the presence of a very high grade shallow dipping vein with 7m @ 72g/t below the Western Zone, and possibly another steeply dipping vein in the hangingwall of the Eastern Zone with 1m @ 162g/t, plus infill in the centre of the Western Zone with 60m @ 7.6g/t, and 31m at 8.2g/t in the Eastern Zone.
- Currently part of a scoping study, the pit (which is dry except for the portal access in the north corner being a relatively shallow ~15m under water) could be dewatered and the old underground workings (which averaged 7.5g/t over 26,000oz from a vein) extended northwards on strike towards the Eastern Zone.
- Higginsville appears to be a relatively new goldfield (it was discovered by Samantha Gold in 1988) that was apparently abandoned when Resolute was distracted by its new African gold mines, and consequently contains a number of targets that can be followed up both from an open-cut & underground perspective. There also appears to be a number of similarities between Higginsville and St Ives.
- Avoca has a number of other prospective exploration targets being those in its own right such as most of Lake Way (south of Wiluna) which is prospective for uranium, gold and nickel and joint ventures, such as with Barrick and Teck.
