The Proposal
The proposal is to increase
the footprint by 2.3ha of the existing Run of Mine (ROM) pad at the Henty Gold
Mine, 23km north of Queenstown. Henty Gold Mine is an underground mine that
produces Gold Doré bars, utilising a Carbon in Leach process to extract gold
from mined ore. Ore is extracted from within the mine then transported to the
ROM pad, where it is crushed and fed into the mill for processing. The purpose
of the ROM extension is to allow for more open area for stockpiling different
materials, which includes unprocessed ore, PAF waste rock and NAF waste rock.
The current ROM area is constraining the ability of the mine to effectively
separate, blend and store these materials, and manage traffic working on the
ROM. The area to be utilised for the ROM extension is currently vegetated with
a mix of native regrowth forest species, and Henty River is located 80 metres
from the proposed expansion.
