**[Rio Tinto plc](https://www.directorstalkinterviews.com/ftse-company/rio-tinto-plc/rio.l)**(
[LON:RIO](https://www.directorstalkinterviews.com/ftse-company/rio-tinto-plc/rio.l))
has disclosed to the Australian Securities Exchange 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. 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.”
