Mongolia, is one of the largest known <a href="/en/products/copper">copper</a> and gold deposits in the world. It is also one of the most modern, safe and sustainable operations in the world.</span></p> <p>The Oyu Tolgoi underground development consolidates our position as a leading global producer of copper, a material essential for decarbonisation and electrification. </p> <p>Open pit mining began at Oyu Tolgoi in 2011 and the copper concentrator, the largest industrial complex ever built in Mongolia, began processing mined ore into copper concentrate in 2013. Current infrastructure at Oyu Tolgoi will allow the mine to operate for decades to come.</p> <p>In March 2023, underground production began at Oyu Tolgoi, making it a high-performing surface and underground integrated copper business and one of the most important copper producers in the world. With the integration of the underground project, a refreshed long-term strategy for Oyu Tolgoi has been released. The strategy named “Creating Prosperity Together”, which was developed in consultation with the Oyu Tolgoi Board of Directors, unites our stakeholders under a shared purpose, ensuring we are prepared to achieve our full potential and deliver on our commitments. Oyu Tolgoi is jointly owned by the government of Mongolia, which has 34% ownership, and Rio Tinto, which owns 66%. Rio Tinto manages the operation on behalf of the owners.</p> <p>At peak production, Oyu Tolgoi is expected to produce 500,000 tonnes<sup>1</sup><span style="font-size: 16px;"> per annum of copper – equivalent to what’s needed to build:</span></p></div> </div> </div> <div class="component rt-component contour__area" style="background: rgb(204, 215, 228)"> <div class="component-content"> <div class="ch-statistics"> <div class="rt-container"> <h2 class="ch-statistics__title">Copper: Essential for a low-carbon future</h2> <div class="ch-statistics__card-list">  <div class="ch-statistics__card"><div class="ch-statistics__card-title-wrapper "> <span class="ch-statistics__card-prefix"></span> <h1 class="ch-statistics__card-title-small">16,400 </h1> <span class="ch-statistics__card-suffix"></span> </div> <h3 class="ch-statistics__card-description ">Electric battery vehicles per day</h3> </div>  <div class="ch-statistics__card"><div class="ch-statistics__card-title-wrapper "> <span class="ch-statistics__card-prefix"></span> <h1 class="ch-statistics__card-title-small">1,580 </h1> <span class="ch-statistics__card-suffix"></span> </div> <h3 class="ch-statistics__card-description ">Wind turbines per day</h3> </div> </div> <div class="ch-statistics__footer"> </div> </div> </div> </div> </div> <div class="component container rt-no-margin--bottom rt-no-margin--top rt-content-block uk-height-match scheme-purple"> <div class="component-content" > <div class="component rich-text component rich-text rt-rich-text--normal-width"> <div class="component-content"> <div class="field-text"><h2>Innovation at Oyu Tolgoi</h2> <p>Most of the value lies deep underground and to reach the ore body we are building a world-class underground mine. It includes a state-of-the-art control room to oversee the operation that will have approximately 200 kilometres of tunnels.</p> <p>We will use leading underground mining technology known as block caving to mine the ore body. Block caving is technically complex, but it is also one of the safest and most cost-effective methods of mining ore from deep below the ground as it uses the force of gravity.</p> <p>Put simply, a void is created under the ore body, which then collapses gradually under its own weight. The ore passes through ‘funnels’ in the rock, known as draw points. A series of lateral tunnels over several levels are used to extract the ore and to haul it for crushing before it is transported to the surface via shaft or conveyor belt.</p> <p>At Oyu Tolgoi, we are using technology to build a connected mine and keep our people safe. We are installing a wireless network to connect our people and equipment underground with the teams on the surface. All team members have a Personal Location Indicator, which allows us to track their whereabouts, providing critical information during an emergency. Similar sensors allow us to track the location and performance of all equipment and we have real time monitoring of atmospheric conditions. The team in Mongolia are supported by the Rio Tinto Underground Mining Centre, which connects our caving experts in the Brisbane hub with our operations team at Oyu Tolgoi. These groups work together to improve safety and productivity performance by using the vast amount of data being collected.</p></div> </div> </div> <div class="component rt-component contour__area" > <div class="component-content"> <div class="ch-statistics"> <div class="rt-container"> <h2 class="ch-statistics__title"></h2> <div class="ch-statistics__card-list">  <div class="ch-statistics__card"><div class="ch-statistics__card-title-wrapper "> <span class="ch-statistics__card-prefix"></span> <h1 class="ch-statistics__card-title-small">5.5m x 5m </h1> <span class="ch-statistics__card-suffix"></span> </div> <h3 class="ch-statistics__card-description ">Average tunnel height and width</h3> </div>  <div class="ch-statistics__card"><div class="ch-statistics__card-title-wrapper "> <span class="ch-statistics__card-prefix"></span> <h1 class="ch-statistics__card-title-small">5 shafts </h1> <span class="ch-statistics__card-suffix"></span> </div> <h3 class="ch-statistics__card-description ">Deepest reaching 1.3KM</h3> </div> </div> <div class="ch-statistics__footer"> </div> </div> </div> </div> </div> <div class="component video" data-properties="{"enableKeyboard":"true","pluginPath":"https://cdn-rio.dataweavers.io/-/media/base-themes/core-libraries/other/","name":"Movie","completedTime":"null"}"> <div class="component-content"> <div class="sxa-video-wrapper"> <video style="width: 100%; height: 100%;" preload="none" poster="https://cdn-rio.dataweavers.io/-/media/content/images/operations/oyu-tolgoi/rt-ot-3d-visualisation.jpg?rev=80dd51de9ea9434a811cf2bcd489ea3d"> <source type="video/youtube" src="//www.youtube.com/watch?v=0dKCUMRd7UE" /> <object type="application/x-shockwave-flash" data="https://cdn-rio.dataweavers.io/-/media/base-themes/core-libraries/other/flashmediaelement.swf?rev=848b6853dcb6449780ef701dd3626b58"> <param name="movie" value="https://cdn-rio.dataweavers.io/-/media/base-themes/core-libraries/other/flashmediaelement.swf?rev=848b6853dcb6449780ef701dd3626b58" /> <param name="flashvars" value="controls=true&poster=https://cdn-rio.dataweavers.io/-/media/content/images/operations/oyu-tolgoi/rt-ot-3d-visualisation.jpg?rev=80dd51de9ea9434a811cf2bcd489ea3d&file=" /> </object> </video> <div class="video-init"></div> </div> <div class="video-caption"> See how we use block caving to transport the ore body at Oyu Tolgoi </div> <div class="video-description"> </div> </div> </div> </div> </div> <div class="component rich-text component rich-text rt-rich-text--normal-width"> <div class="component-content"> <div class="field-text"><h2>Growth</h2> <p>Global demand for copper is set to grow, driven by urbanisation, industrialisation and increasing requirements for renewable energy: copper plays a key role in electrification and power production.
