A well-known New Zealand geologist made a case for new exploration in the Golden Blocks region of the Tasman district of the upper South Island.
Dunedin-based geologist Paul Angus, who has undertaken search work at Macraes, Reefton and Sams Creek to name three regions, gave a presentation at the AusIMM New Zealand Mining Conference in Tauranga last week.
The talk was on behalf of Strategic Elements Ltd (ASX: SOR) which indicated in an ASX announcement that exploration would be undertaken once land access is secured.
The Perth-based company has held Golden Blocks for years and, due to its diverse portfolio, often has not cited work in the area, which takes in the historic Aorangi mine that produced high-grade gold from relatively low tonnages mined by oldtimers.
Strategic said total gold output from Aorangi was reportedly 46,000 ounces at an average grade of 36 grams/tonne gold, between 1898-1914.
Paul Angus said Golden Blocks was an excellent regional development project for the Tasman region where past data and recent research has shown gold ore was free milling and there was scope to treat ore offsite at the currently dormant Reefton gold mill, owned by OceanaGold Corporation (TSX & ASX: OGC).
The Aorangi mine was still operating in high grade ore when work ceased due to the onset of the First World War.
Angus said that in contrast to the Reefton and Lyell gold fields the Golden Blocks area “has mappable gold units.”
He said parallel reefs lie on the contact between the Anthill Black Shale and Battery Member at Aorangi, and between the Battery Member and Jimmy Creek Quartzite.
