The Greymouth Coal Project is a
proposal to mine by the application of proven hydraulic, and room and pillar
underground mining methods; and to process the equivalent of an average of 1.7
million tonnes per year over a forty-year period. The proposed mine site is
located ten kilometres north of Greymouth, on the west coast of the South Island
of New Zealand. Of the three separate mineable seam groups, the thick Main Seam
Group, which makes up 77% of the total resource, will be mined by hydraulic
mining technology.

It is proposed to market and produce a high
volatile bituminous type coal with low ash (6%) and sulphur (0.4%). Because the
inherent ash content is low, the requirement for coal treatment will only be the
use of a single cell jig circuit to control the effects of rock dilution and
partings. The resulting coal product is tentatively planned to be transported by
rail to the port at Lyttelton for loading on to Panamax or Post Panamax size
vessels.
