11:38:59OceanaGold report details a broader
exploration quest in NZ
Ross Louthean — 4 April 2011
A detailed report by OcenaGold Corporation (ASX, NZX & TSX:
OGC) shows that the company is broadening its exploration in the
Macraes region outside of its mining environment.
The Annual Mining Form released by the company late last week said
a focus was now being made on “best strike extension target”, the
Coronation deposit, about 8 kilometres north of the current
mining-milling infrastructure.
The report also iterated the point that exploration was continuing
on the downdip and plunge of the established open pits – taking in
Round Hill, Innes Mills, and Frasers.
A new programme of structural mapping at surface of the open cuts
and historical prospects was planned to advance understanding of
the controls on mineralisation.
In the Reefton goldfield, the project takes in four open pits, the
established Globe-Progress mine and the now well identified
along-strike General Gordon, Empress and Souvenir.
The four pits take in 2 kilometres of a mineralised shear zone.
Based on known reserves a further 380,000 ounces was expected to be
produced from these zones from the beginning of 2012.
The report said a deep drilling programme was underway to test for
downdip potential of the Birthday Reef at the historic Blackwater
mine at Waiuta within the goldfield.
The Blackwater project has been a stop-start exercise for the
company going back about a decade and, at one stage, a headframe
was placed over the main shaft but the shaft was found to be less
sound than originally perceived.
Blueprints for Blackwater’s development have included developing a
decline mine from near the Snowy River to access the mineralisation
below the workings that were eventually mothballed in the
1950s.
In 2010 the Globe Progress mine produced 85,342 oz, about 12% more
than the previous year. Concentrate from Reefton is sent to the
Macraes process facilities where it is campaign treated through the
pressure oxidation plant.
The operation crushed 1.278 million tonnes of ore and produced a
milling head grade of 2.6 grams/tonne, marginally better than
2009.
