The Reefton Goldfield, both historically and potentially,
represents a significant gold producing camp in the Westland province of New
Zealand. Some two million ounces of gold have been produced from the Greenland
Group host rocks between 1870 and 1951 with the most significant producers being
the Blackwater and Globe Progress mines.

Steep terrain, high rainfall, poor outcrop, widespread
fluvio-glacial deposits, tertiary cover and sometimes onerous environmental
access conditions have proved a challenge to conventional exploration
techniques. In addition classic exploration techniques have come up against a
desire to reduce exploration cycle time and exploration costs while increasing
both quality and quantity of geological information.

The trial, and subsequent
implementation, of Wacker sampling has proved a highly successful and effective
geochemical tool currently being utilised to target, discover, and define
potential economic gold mineralisation in the Reefton
Goldfield.
