Gascoyne advances feasibility studies at Dalganranga
PERTH (miningweekly.com) – Gold hopeful Gascoyne Resources has selected a preferred process plant design for its proposed Dalgaranga project, in Western Australia, with the company revealing on Wednesday that the plant would require a capital investment of some A$60.5-million.
The process plant design formed part of a prefeasibility study currently being undertaken at the Dalgaranga project, which was scheduled for completion in March this year.
“Confirmation that the Dalgaranga gold project can be progressed with a relatively low capital cost is very welcome news. The deposits at Dalgaranga have a number of unique characteristics that Gascoyne and Mintrex have identified, which will result in lower than normal capital and operating costs, including the very soft nature of the ore, the excellent metallurgical recoveries, rapid leaching and very low reagent consumption,” said Gascoyne MD Mike Dunbar.
He noted that when combined, the characteristics of the Dalgaranga ore had a substantial impact on the cost of development.
The processing plant was envisioned as a 2.5-million-tonne-a-year single-stage crushing and semi-autogenous grinding mill, which would include gravity gold recovery and leaching tanks.
Ancillary infrastructure was expected to cost an additional A$14.5-million, and working capital requirements were still being prepared.
It was expected that the Dalgaranga project would produce some 100 000 oz/y of gold with a mine life of around six years, based on the current resource of 23.7-million tonnes, grading 1.4 g/t gold for 1.05-million ounces of contained gold.
