Sandfire extends life of DeGrussa mine
May 11th, 2018
Sandfire Resources has extended the mine life of the DeGrussa copper-gold operation in Western Australia.
The Perth-based company today updated the operation’s mine plan, mineral resource and ore reserve, including outcomes of a review of unconverted measured and indicated resources in technically and economically assessed zones, resulting in their conversion to ore reserves.
This, together with an upgrade to the mineral resource at the Conductor 5 deposit, has added around 1.3Mt of copper, at 3.5 per cent grading, for 46,000t of copper to the DeGrussa reserve.
DeGrussa’s mine life has been extended to early-2022, from the previous 2021 outlook, with the upgrades. The updated mine plan, incorporating the near-by Monty mine, now totals 6.6Mt, at grading 5 per cent copper and 1.6g/t gold, for 332,000t of contained copper and 354,000oz of contained gold.
Sandfire managing director Karl Simich said the updated mine plan and ore reserves reflected the success of diligent work programs completed over the past 6–12 months to re-evaluate key zones of mineralisation within the broader DeGrussa underground mineral resource inventory. Read more…
