Chair's statement
I begin this report by recognising, with great sadness, the death of a
colleague at the SimFer site in Guinea on 14 February. This tragedy
follows the death of Mohamed Camara in August at the same site, a
loss that was felt deeply across the business. We hold both
teammates’ families, friends and colleagues in our thoughts, along
with all those affected. We have taken immediate action to
understand the causes of both tragedies and we will continue to
strengthen our practices to ensure our people’s safety.
In a further 12 months characterised by geopolitical volatility and
rapid technological progress, one truth became increasingly clear:
now, more than ever, the world needs mining. The materials we
provide not only fuel modern life but also enable underlying
infrastructure for the technology revolution and energy transition.
And volatility and fragmentation has increased the imperative and
awareness of the need for critical minerals.
In the second half of last year, the Board appointed Simon Trott to
lead Rio Tinto as Chief Executive. He succeeds Jakob Stausholm,
who was instrumental in rebuilding trust with our key stakeholders
and prepared the ground for our future growth, both strategically and
culturally. The Board is deeply grateful to Jakob for his leadership
and service.
Mining at its best
In this next phase for Rio Tinto, the Board and leadership team have
focused on implementing a stronger, sharper and simpler way of
working across the business.
Our strong operating performance over the year shows that we are
building on a firm foundation. And over 2025, I saw first-hand the
strong progress being made at many of our sites as we deliver on
this work.
At Oyu Tolgoi in Mongolia, I witnessed how we are extending the
frontiers of mining technology. Here, we are ramping up copper
production from an orebody more than 1,300 metres underground
and comparable in size to Manhattan.
That same operational excellence was evident at our lithium sites in
Argentina. There, I saw our progress in supplying customers with
high-quality, battery-grade lithium carbonate.
In Canada, I met the teams operating our technologically advanced
aluminium smelters in Quebec. I also spent time with colleagues
who are driving efficiency-boosting innovations in our iron ore
business in Quebec and Labrador.
And across the year, I saw time and again, Rio Tinto’s ability to build
strong and meaningful partnerships.
In November, I joined the celebrations to mark first ore at Simandou
in Guinea. This massive achievement was made possible by a
unique partnership, consisting of the Government of Guinea,
Chinalco, Baowu and WCS. Beyond the mine, the project delivers a
major new source of high-grade iron ore to the world, a more than
620-kilometre multi-use railway and world-class port facilities.
Simandou also promises to bring vast potential economic benefits
and could grow Guinea’s GDP by up to 55% by 2030.
Responding to a changing world
I said in our 2024 Annual Report that we are living in uncertain times
and this has proved to be something of an understatement.
I am confident in our ability to navigate geopolitical challenges. Our
agile response to US trade tariff volatility exemplified this capability.
Equally, our diversified portfolio of world class assets, balance sheet
strength and focus on operational excellence and project building
enable us to respond to shifting demand in a more regionalised,
protectionist world.
Climate change is another factor shaping how we operate.
The massive cyclones in the Pilbara at the start of the year
reminded us that extreme weather conditions can materially
affect our operations. Against this backdrop, we believe our
commitment to our decarbonisation targets, which we reaffirmed in
our 2025 Climate Action Plan, is both environmentally responsible
and in our shareholders’ long-term interests.
Our operations’ benefits must be felt beyond the mine gate and within
the communities who host us. Over 2025, we strengthened our social
licence and relationships with Indigenous Peoples and communities.
In June, we opened the Western Range iron ore mine in Australia,
which we developed with our joint venture partner China Baowu
Group, in close collaboration with the Yinhawangka People.
It showed what can be achieved through meaningful engagement
with Traditional Owners in mine planning and development. We built
on this milestone by updating 3 agreements with Pilbara Traditional
Owners, reflecting modernised partnership expectations. While
these agreements mark significant progress, we know there is still
more to do.
Moving forward together
Our achievements in 2025 would not have been possible without
our people. Across Rio Tinto, we continue to build a positive, values-
driven performance culture, creating the right conditions for success.
Our aim is for our people to feel safe, respected and accountable for
their work, and confident that their voices and ideas are heard.
In turn, our colleagues’ dedication is creating a Rio Tinto that is
valued for how it performs, and the way it works with others. We
look to the year ahead with optimism, as we build on our already
strong momentum to deliver industry-leading shareholder returns
and lasting value for our stakeholders.
My thanks, and that of the Board, go to our people, partners,
customers, suppliers, investors, and governments, Indigenous
Peoples and communities for their support throughout 2025.
