Rio Tinto reveals maiden Resource at Winu and new discovery
28 Luglio 2020 - 12:45AM
Business Wire
Rio Tinto has disclosed the maiden Inferred Mineral Resource at
the 100% owned Winu copper-gold project and revealed the discovery
of a new zone of gold dominant mineralisation approximately 2 km
east of the Winu deposit in the Paterson Province of Western
Australia.
The Inferred Mineral Resource, reported at a 0.2% copper
equivalent cutoff, is 503Mt at 0.45% copper equivalent (CuEq). This
includes a higher grade component of 188Mt at 0.68% CuEq at a
cutoff grade of 0.45% CuEq.
Study work to date suggests the copper mineralisation supports
the development of a relatively shallow open-pit mine, combined
with industry-standard processing technology that is used at other
Rio Tinto sites. Drilling continues to refine the overall geometry
of the system and controls. The deposit remains open at depth as
well as to the north and southeast Figures 1 to 4. The Winu project
team continues to work with local Nyangumarta and Martu Traditional
Owners and regulators to progress the agreements and approvals
required for any future development. We are targeting first
production from Winu in 2023, subject to securing all necessary
approvals.
The discovery of a new zone of gold dominant mineralisation
approximately 2 km east of the Winu deposit, at a prospect called
Ngapakarra, as well as a number of other encouraging drilling
results in close proximity to the maiden Winu Resource, provides
further encouragement about the potential for the development of
multiple ore bodies within one system.
Rio Tinto group executive of Growth & Innovation and Health,
Safety & Environment (HSE) Stephen McIntosh, said “We’re taking
a more agile and innovative approach at Winu, and are working on
the studies for a small-scale, start-up operation focused on Winu’s
higher-grade core as we take another step towards commercialising
this deposit. We are also assessing options for future expansion in
the Paterson region given the extent of mineralisation identified
to date and our large land package.”
“The additional exploration results reported today support our
view that there is potential to develop the Paterson region into a
large-scale operation over time through both our 100% owned
tenements and joint ventures. We’ve so far carried out exploration
activity in just 2% of our tenements in the region and we’re
building on this discovery at Winu with further encouraging
results.”
Rio Tinto chief executive of Copper & Diamonds, Arnaud
Soirat, said “We are very pleased with the progress at Winu as it
adds a further option to our strong copper portfolio in a country
that is home to many of Rio Tinto’s world class operations.”
