New online platform gives a transparent view of our surface water use
In some places we operate, water can be scarce. In others, we have to remove water to operate safely. Everywhere we work, we share this important resource with local communities, whose health, safety and livelihoods also rely on them.
So it’s critical that we manage water at all of our operations carefully – and transparently.
Sharing our water usage
In 2019, we set ourselves a goal – by the end of 2023, we would disclose how much surface water we were allocated, and how much we were using.
Early in 2023, we launched a new, interactive platform that shows our surface water allocations and usage at our sites.
It’s kind of like Google Maps, but for water.1 No matter where we are in the world, anyone, anywhere can check how we’re using the surface water we’re allocated.
A tool of this kind is an industry first, both in the level of detail provided, and way it’s published on an intuitive geo-location platform. And surface water is just the beginning – we want to disclose more across our ESG performance, and will be working on plans to achieve that soon.
By making this information clearly and easily accessible to everyone, we’ll be able to have more meaningful conversations with governments, partners, and communities we work with about how we use water across our operations around the world.
We’re also publishing all our surface water allocation and usage data from the past five years. And we can provide additional historical data on request.
Managing different water risks across our operations
Water is a precious resource, so we know we need to balance our operational needs with those of local communities and ecosystems.
We manage a range of water risks across our business, so we’ve set targets – tailored to the specific challenges at each site – and publicly report on progress against each one.
In addition to a company-wide goal, we set six site-based targets based on their water risk profile, our International Council on Mining & Metals (ICMM) commitments, and local community and environmental interdependencies.

Rio Tinto is proud to support the Indigenous-led archaeological research project
The sites around Taticheck lake are unique and abound in historical significance. Thousands of artefacts, village sites and human remains can help us better understand our past. Supporting this Indigenous-led research project as a partner to the Cheslatta Carrier Nation was something we wanted to be a part of.
This weekend we had the honor to attend a Cheslatta Carrier Nation campout to announce the partnership and learn more about their heritage.
At Rio Tinto, we are humbled that we get to play a small role in discovering and learning more about Indigenous culture and traditions that could impact how we understand the history of human migrations in North America.
Rio Tinto BC Works’ Operations Director Andrew Czornohalan attended the campout and shared the importance of the partnership to him with his colleagues (see below).
Here’s a great news piece that talks more in-depth about the partnership https://lnkd.in/gwK_v7rA.

Rio Tinto’s Andrew Czornohalan’s message to the BC Works Team
Colleagues,
The Cheslatta Carrier Nation and Rio Tinto are embarking together on a significant archaeological project to excavate cultural and historical sites, some with an estimated 10,000-year-old history.
Rio Tinto will contribute CAD $2.8 million dollars to this remarkable Cheslatta led project that will help archeologists collect, preserve and study artifacts found around Tatichek Lake, which sits on the southeast side of the Nechako Reservoir. This will be the first archaeological project of this magnitude that Rio Tinto will be sponsoring in North America and it sits right in our backyard.
Over the weekend, I had the incrediblyunique opportunity to visit the Tatichek archaeological site. There is something so humbling to stand in a place that has such extraordinary history, where important conversations were held, and memories were made. The sense of humanity and connection, really a window to the past was overwhelming, thinking of those who lived, shared, loved, laughed, lost, struggled and triumphed in this location over countless generations will live with me for my lifetime.
As we explore and study these unique sites and artifacts, we will gain insights into past lives and establish timelines of occupation, trading networks, and resource gathering. Through archaeology, pieces history can be reconstructed, and we can understand so much more about the way of life, the culture and the traditions of people. It will also enhance our understanding of the Indigenous communities and human migration patterns in North America. It was believed that Tatichek Lake was located on one of three major migration routes that brought humans all the way from Alaska to the southwest of the United States.
This project aims to preserve and protect unique elements of Cheslatta heritage that we are grateful to be able to recover after the flooding and forest fires that this land has experienced. This project will have a tremendous impact on the reflection and rebuilding we continue to do to strengthen the relationship with the Cheslatta Carrier Nation and the learnings and lessons we take with us into the future.
We truly appreciate and it is quite humbling reflecting on the trust Cheslatta has in us to be part of this project. We will continue to build upon the New Day agreement and strengthen the relationship between the Cheslatta Carrier Nation and Rio Tinto. This project represents a significant step forward in building a more respectful and inclusive future and we are very proud to be a part of it.

Should you have any questions or concerns, or require additional information, please do not hesitate to reach out by reply email, or through one of the methods listed below.
Do you know about Rio Tinto’s partnership with UNBC?
The Tahtsa Ranges Atmospheric Rivers Experiment (TRARE) is part of the natural Sciences and Engineering Research Council of Canada (NSERC)/Rio Tinto Industrial Research Chair project. This is a five-year long project that has many different components dedicated to examining the hydrology of the Nechako River Watershed. This experiment is super exciting because it’s the first of its kind in Canada!
Dr. Stephen Dery is the lead on this project and has been researching Pineapple Express Storms. These storms are actually rivers in the sky that originate in the Pacific Ocean and bring LOTS of moisture to the north. Dr. Dery and his team are studying how much and what type of precipitation these storms produce to better understand how they affect the Watershed. With climate change, these storms will occur more frequently which can raise the water levels and cause landslides or washouts and harm the surrounding ecosystems. Knowing how Pineapple Express Storms affect the water, it can be easier to predict high water levels and plan accordingly.
Great work being done by Dr. Dery and his team!
