Deposits
Under the Mount Goldsworthy
Agreement Act 1964 and the
Goldsworthy–Nimingarra Agreement
Act 1972 between the State of
Western Australia and the
Goldsworthy Mining participants,
development has taken place over a
number of mining areas within the
Pilbara region, to date exclusively
from banded iron formations in
greenstone sequences in the north
Pilbara. Mount Goldsworthy, Sunrise
Hill, Shay Gap and Yarrie have
satisfied development of areas A and
B of the Mount Goldsworthy
Agreement areas. Area C, in the
Hamersley Basin, is the third grouping
for development under the Agreement
and was first promoted for
development in the early 1970s.
Mining Area C comprises a number of
Marra Mamba and high-phosphorus
Brockman deposits in the central
Hamersley Ranges. The initial
development is based at Deposit C, a
Marra Mamba deposit, 100 km westnorthwest
of Mount Newman.
Resources
A total of 204 Mt at 62.7% Fe of
Marra Mamba ore reserves are
delineated in Deposit C.
A further 760 Mt of Marra Mamba
and 40 Mt of detrital resources are
defined within the Mining Area C
lease.
Brockman ore deposits, exceeding
110 Mt of +58% Fe, high-phosphorus
resources, are estimated over a
number of deposits within the lease
area.
