Avoca Resources Limited (AVO) –Targeting Gold Production >200,000ozpa from Two Operating Mines by 2009

• The recent acquisition of Chalice and its tenement package has opened up a significant number of drill-ready targets for potential mineralisation that could become a second mine or additional ore source for Avoca’s developing Trident mine near Higginsville in WA, and take its production well beyond 200,000ozpa.
• The supergene discovery at Wills (~25km north of Trident), lends weight to our (ERA) expectations that the new Higginsville mill could treat ~1mtpa from the Trident underground, and ~0.2mtpa to 0.3mtpa from the numerous near surface open-cuts and low grade stockpile resources for many years to come.
• At AVO’s Higginsville operation, two drives intersected Trident’s Eastern Lode ore in July 2007, namely the steeper dipping Eastern Lodes (on 1170 Level), and the flatter dipping Eastern Lodes (on 1155 level), starting to build an ore stockpile.
• Exploration appears to be establishing that the gold veins at Poseidon extend from the old pit through the Poseidon South underground, and then directly link through Trident to the recent intersections 200m north of Trident (and still open north on strike), with the pyrrhotite and arsenopyrite (non-refractory, more crystalline) event providing the spice for the higher grades.
• At Chalice itself, there are a number of possibilities post dewatering the old open-cut, with unmined ore under the southern wall, a series of IP anomalies to be drilled that have similar signatures to Chalice, and the Cavalier Prospect which has surface mineralisation and intersections resembling that above Trident.
• The interim treatment of Trident ore before the 1mtpa (rated hard) plant is completed by mid (June/July) 2008 has become more complex with two solutions (Paddington and Norseman) having fallen into AIM listed (private equity backed) hands, and consequently toll treatment costs at all available plants have soared to unfriendly (ERA’s viewpoint) >A$30/t levels (which could delay planned stoping).
