Veolia wins two-year water management contract renewal at AngloGold Obuasi

Environmental, Mine operation news, Mining services, Precious metals, Water management, , , , ,

Veolia says it has renewed its contract with AngloGold Ashanti Ghana Limited, part of the South Africa headquartered gold mining company, AngloGold Ashanti, with Veolia Ghana Limited continuing to be responsible for operating and maintaining all the water treatment plants for the Obuasi open-pit and underground operations in Ghana.

These two-year extension confirms Veolia’s operational know-how in the preservation, depollution and renewal of water resources for the mining industry, it says.

Six facilities are required to guarantee the treated water and discharge quality for AngloGold Ashanti’s Obuasi mine: four wastewater treatment plants and two drinking water treatment plants.

This water is used in various activities associated with the exploration, extraction and transformation processes associated with mining, whether that is to process ore, remove dust, transport sludge, or supply employees needs. In a tropical climate subject to highly seasonal heavy rainfall, it is the Ghanaian gold mine’s responsibility to manage its wastewater and its process residue in order to comply with the local Environmental Protection Agency’s requirements in terms of discharges into the ecosystem.

Veolia, in 2019, was originally awarded a four-year contract to carry out these services at Obuasi. During these four years, it was awarded “Best Contractor Company in Quarter 3 2022” by AngloGold Ashanti Ghana, having worked more than 1 million hours without a single accident-related stoppage. Veolia also managed to comply with the environmental requirements in force by producing nearly 33.5 million cu.m of water, including about 7 million cu.m of drinking water for the needs of the site and surrounding communities.

Philippe Bourdeaux, Veolia’s Executive Vice President, Africa and Middle East, said: “Our group works side by side with industrial companies to respond to the major challenges they face, both in Africa and around the world. Veolia will continue to make its know-how
available to AngloGold Ashanti and to the mining industry to manage water as a finite and endangered resource.”

AngloGold eyes autonomous haulage advantages at Nevada project

Automation, Mineral project development, Mining events, Precious metals, , , , , , , , , , , , ,

AngloGold Ashanti says it is considering the use of autonomous haulage at its Expanded Silicon project, in Nevada, USA, as part of plans to leverage new technology at the in-development asset.

Speaking on a roundtable discussion titled ‘Beyond the hype: how technology can drive mining operations performance’ organised by global subsurface software company Seequent, Marcelo Godoy, Chief Technology Officer at AngloGold Ashanti, said the company was studying the application of autonomous haulage to optimise efficiency and reduce risks at its projects in Nevada.

Discussing automation and robotics as one of three transformational technologies the company is looking to leverage to achieve its net-zero emissions goals by 2050 – electric vehicles and renewable technologies being the other two – Godoy said he saw robots running key production activities at the company’s mines by the time they reach net-zero emission status.

AngloGold has been leveraging automation in its drilling operations, with Godoy noting on the roundtable that the company was seeing improvements in terms of efficiency, precision and safety.

“We also make extensive use of semi-autonomous LHDs in our underground mines, and we are studying the application of autonomous haulage vehicles to optimise efficiency and reduce risks in our projects in Nevada,” he said.

Asked to expand on this by IM after the roundtable, he said: “Our Nevada projects are conceptualised as open-pit mining operations and, at this point, we are only looking at autonomous haulage.

“As far as I know, there is no proven and off-the-shelf autonomous loading technology that could successfully work in the hard-rock environments where we operate. Autonomous loading is still an ongoing technological development and I expect that it will become prevalent in the mining industry before the end of this decade.”

He added that the option of autonomous haulage is being considered at the company’s Expanded Silicon project, which builds off AngloGold’s discovery of the Silicon gold deposit in the Beatty District of Nevada.

In 2022, the company outlined a maiden inferred resource estimate of 3.37 Moz of gold at a grade of 0.87 g/t Au and 14.17 Moz of silver at 3.66 g/t Ag contained within a base of 120.4 Mt. A prefeasibility study is being worked on currently.

Pacific Energy to integrate more ‘clean energy’ into Tropicana gold operation

Environmental, Mine operation news, Mining services, Power supply for mines, Sustainable mining, , , , , , , , , ,

Pacific Energy says it has been awarded the contract to integrate 62 MW of clean energy into its existing 54 MW gas fired power system at the Tropicana gold mine, 330 km northeast of Kalgoorlie in Western Australia.

Tropicana is owned by AngloGold Ashanti Australia Ltd (70% and manager) and Regis Resources Ltd (30%).

The renewable expansion of the existing power system will be delivered under a 10-year build-own-operate agreement. When completed, the 116 MW power station will be the largest off-grid hybrid investment in the power provider’s portfolio, and, at time of contract, the largest off-grid gas-wind-solar-battery storage facility in the Australian resources sector, according to Pacific Energy.

The expansion will incorporate four 6 MW wind turbines, a 24 MW solar farm and a 14 MW battery storage system (BESS). The integrated power facility’s intelligent control system, which has been developed in-house by Pacific Energy, will optimise input from the high penetration renewable energy and storage technologies and allow the system to run hydrocarbons-free for extended periods of time, the company says.

Pacific Energy has designed the new system to support AngloGold Ashanti’s strategy of reducing its global net carbon emissions from energy use by 30% by 2030, as part of its roadmap to net-zero carbon emissions by 2050.

Overall, the renewables integration is expected to reduce Tropicana’s diesel and gas consumption for power generation by 96% and 50% respectively, slashing carbon emissions by an average of 65,000 t/y over the life of the agreement, according to Pacific Energy.

Pacific Energy Chief Executive, Jamie Cullen, said: “This is an excellent outcome for our long-time client, AngloGold Ashanti. We’ve been on the journey with them since 2012 and we are incredibly pleased to apply proven global technologies and our in-house expertise to help decarbonise their operations without losing power reliability or efficiency.

“To date, we are the only operator to successfully supply hydrocarbons-free power to mine sites in Australia.

“We expect our new system to reduce the mine site’s overall power generation emissions by 50%. It’s a really exciting prospect for us and AngloGold Ashanti, and one we’ve worked hard to achieve on our client’s behalf.”

Delivery of the project, which is slated to be Australia’s most remote large-scale hybrid power system, will be coordinated by Pacific Energy’s Remote Energy and Integrated Renewables divisions. The company will capitalise on its fully-integrated capabilities by manufacturing the BESS, high-voltage switch room and PV ring main units in house at its Western Australia-based facilities, it says.

Pacific Energy is expected to begin site works in July this year, with the project due for completion in early 2025.

MacLean is set to showcase its SS5 battery-electric vehicle (BEV) Shotcrete Sprayer at the Underground Operators Conference 2023 (UGOPS), in Brisbane, Australia, next week, but it also has one eye on the unit’s first mine site trial at the AngloGold Ashanti-owned Sunrise Dam operation in Western Australia.

Attendees of UGOPS will get a first-hand look at the EV Series™ product on the company’s booth. This battery-electric shotcrete sprayer has been put through its paces at the Maclean Research & Training Facility in Sudbury, Ontario, and is equipped with the likes of Quickscan thickness imaging and Chemsave accelerant savings technologies.

Alongside celebrating its 50th year of existence as an Ontario-headquartered company, 2023 is a landmark year for MacLean Australia, with multiple MacLean BEVs starting to arrive in-country to be introduced to Australian mining companies and mining contractors. One such contractor is Barminco, which is set to receive the SS5 for testing at Sunrise Dam. Sandvik’s 65-t-payload battery-electric truck, the TH665B, is also set for field testing at the same operation.

MacLean has had a full-service parts and technical support branch in Perth, Western Australia, for over a decade and, in 2021, opened a second service and support branch in Orange, New South Wales, to support a growing fleet of MacLean mining vehicles in underground mining hubs in the eastern region of the country.

Jari Tuorila, MacLean GM for Australasia, said: “We are really looking forward to the UGOPS event and showing – not just telling – the Australian mining industry exactly what the value proposition of MacLean EV Series product line is. When we say, ‘EV-proven, EV-ready’, we mean it. It’s not just a slogan. Over 50 MacLean BEVs have been commissioned around the mining world since the MacLean Fleet Electrification program was launched in 2015, with a quarter million operating hours logged, and we’re only at the starting line for Australia.

“Our message to our industry colleagues is simple – we have a diesel-free production support fleet option for you, right now. We can’t wait to welcome visitors to our booth to see the BEV shotcrete sprayer in person and speak with our team of technical experts, which will include product management and engineering colleagues from Canada.”

Patrick Marshall, MacLean’s Brisbane-based Vice President of Technology, added: “The UGOPS showcase is just the kick-off to a multi-stage introduction of MacLean EV Series technology to Australia across 2023. The minute the show closes on March 29th, the MacLean Australia team will be turning their attention to shipping the BEV SS5 unit to Barminco at Sunrise Dam, where it will be trialled by the contractor throughout the summer. We are committed to seeing this real-world trial succeed and then build on that success to more broadly introduce MacLean fleet electrification to the Australian industry.”

Gold Fields and AngloGold Ashanti agree on deal to create Africa’s largest gold mine

Mine operation news, Precious metals, Sustainable mining, , , , , , ,

Gold Fields and AngloGold Ashanti have agreed the key terms of a proposed joint venture in Ghana between Gold Fields’ Tarkwa (pictured above) and AngloGold Ashanti’s neighbouring Iduapriem mines to create what they say will be the largest gold mine in Africa and one of the largest in the world.

The Tarkwa mine is held by Gold Fields Ghana, in which Gold Fields currently owns a 90% share and the Government of Ghana (GoG) holds 10%. The Iduapriem mine is currently 100% owned by AngloGold Ashanti. Both mines are located near the town of Tarkwa in the country’s Western Region.

The parties have agreed in principle on the key terms of the proposed jv and have commenced with preliminary, high-level and constructive engagements with senior government officials in Ghana and will continue engaging with the GoG, relevant regulators and other key stakeholders, with a view to implementing the proposed jv as soon as practically possible. They have also agreed to mutual exclusivity during this engagement.

It is intended that the jv will be an incorporated joint venture, constituted within Gold Fields Ghana and operated by Gold Fields. AngloGold Ashanti will contribute its 100% interest in Iduapriem to Gold Fields Ghana in return for a shareholding in that company.

The companies do not anticipate that any material, additional capital injection will be required by either company to establish the proposed jv, and is expected to materially improve its capital intensity once operational.

Excluding the interest to be held by the GoG, Gold Fields will have an interest of 66.7%, or two-thirds, and AngloGold Ashanti will have an interest of 33.3%, or one-third, in the jv.

The Iduapriem mine is currently 100% owned by AngloGold Ashanti

The companies said: “The proposed jv would create the largest gold mine in Africa and one of the largest in the world. It will be a high-quality operation, supported by a substantial mineral endowment and an initial life spanning almost two decades.”

Operational synergies will be achieved by optimising mining of the combined orebodies and consolidating the infrastructure of the immediately adjacent mines for the long-term benefit of all shareholders and stakeholders, the companies said.

Martin Preece, Interim CEO of Gold Fields, said: “The proposed jv is an exciting opportunity to combine mining operations that are essentially part of the same mineral deposit and is something that Gold Fields and AngloGold Ashanti have discussed many times before over the years. The ability to optimise mining and the use of shared infrastructure across the combined operation will result in significant flexibility in mine planning, materially enhancing the economics of the mine and ensuring quality and scale of operation that will be world class. That unlocked value will underpin the proposed jv’s continued contribution to our host communities and Ghana for decades to come. For Gold Fields, it will also significantly enhance the overall quality of our portfolio.”

Alberto Calderon, CEO AngloGold Ashanti: “This combination puts together two parts of the same world-class orebody, allowing us to share skills and infrastructure to significantly enhance every aspect of this mining operation, from exploration and planning, to mining and processing. By creating one of the world’s largest open-pit gold operations, in a pre-eminent mining jurisdiction, we will create longer-term value not only for AngloGold Ashanti and Gold Fields, but for the combined stakeholders in our local host communities and for all of Ghana.”

The combined operation comes with an estimated life of at least 18 years, which could increase through an extension and optimisation plan to be considered under the proposed jv over the next three years, and which could also enhance envisaged production and cost parameters.

It would come with estimated average annual production (100% basis) of almost 900,000 oz over the first five years and average annual production in excess of 600,000 oz over the estimated life of operation. All-in sustaining costs (in 2023 terms) were expected to be less than $1,000/oz over the first five years and less than $1,200/oz over the estimated life of operation.

AngloGold Ashanti says it is weighing up the potential introduction of battery-electric vehicles at its Cuiaba mine in Brazil as a small part of a wider initiative to achieve a 30% absolute reduction in its Scope 1 and 2 Greenhouse Gas (GHG) emissions by 2030.

The company says this carbon emission reduction target could be met through a combination of renewable energy projects, fleet electrification and lower-emission power sources. The company has already reduced its absolute GHG emissions by more than two thirds since 2007, and remains committed to achieving net zero emissions by 2050.

The targeted reduction announced today, from a 2021 baseline of 1.4 Mt of carbon dioxide equivalent (CO2e), aims to see emissions from the company’s activities diminish to about 1 Mt by the end of the decade. When growth projects are factored in, including those in Nevada and Colombia, AngloGold Ashanti is targeting a 46% reduction in emissions by the end of the decade.

The capital cost required to achieve these reductions over the coming eight years is anticipated to be about $1.1 billion, of which $350 million will be funded over that period by AngloGold Ashanti and the remaining $750 million through third-party funding, including from providers of renewable energy infrastructure. The company plans in the coming weeks to initiate a process to secure a green funding facility of $250-300 million to finance its portion of these decarbonisation initiatives across its business.

“We have a clear pathway to achieve our target by 2030, when we expect to have lowered our overall emissions by almost a third,” AngloGold Ashanti Chief Executive Officer, Alberto Calderon, said. “This ensures we continue to do our part in reducing our carbon footprint, while also improving the value of our business.”

The targeted reductions announced today incorporate initiatives at each business unit including the introduction of renewable energy, cleaner grid power and partial fleet electrification.

Approximately 60% of the planned emissions reductions will come from large renewable energy projects including wind and solar projects at the company’s Australian operations and solar-power plants at both Siguiri in Guinea and the Iduapriem and Obuasi operations in Ghana, AngloGold said. In addition, a prefeasibility study has commenced at the Cuiaba mine in Brazil to confirm the benefits of replacing some mobile fleet with battery-electric vehicles. AngloGold will also be working with Sandvik to trial underground mining’s largest-capacity BEV truck, the 65-t payload TH665B at Sunrise Dam.

The Cuiabá complex includes the Cuiabá and Lamego underground mines and the Cuiabá and Queiroz plants. Ore from the Cuiabá and Lamego mines is processed at the Cuiabá gold plant. The concentrate produced is transported by aerial ropeway to the Queiroz plant for processing and refining. Total annual capacity of the complete Cuiabá circuit is 1.75 Mt.

The viability of a wind farm at Cerro Vanguardia in Argentina is also being investigated. The vast majority of these projects are expected to be NPV-positive adding value to the business by reducing energy costs and improving energy security, the company said.

Two “clean grid” initiatives are already close to completion – a switch from diesel generation at the Geita mine site in Tanzania to the country’s national power grid, which has a high proportion of power sourced from gas and renewables, and the transition to full hydro-grid power in Brazil.

Our comprehensive mine control and fleet management solution enhances the productivity and profitability of a mine through real-time or near-real-time data.”

The open and scalable technology provides flexibility to incorporate equipment, systems, locations and network assets as needed. From an executive team analysing profit, operations managers optimising productivity, to operators tracking progress, Micromine Pitram provides stakeholders at every level with greater visibility, control, and understanding of operational activities, according to the company.

“Micromine Pitram is used and trusted by many of the world’s largest mining organisations, and this agreement is just another fantastic example,” Birch added.

As per the agreement, Micromine Pitram will be deployed at Sunrise Dam and Tropicana this month.

Sunrise Dam is predominantly an underground operation with average production of 2.7 Mt/y of ore. Tropicana, a joint venture between AngloGold (70%) and Regis Resources (30%), is an open-pit mine and underground mine.

Last week, AspenTech and the owners of Micromine entered into a definitive agreement for the former to take over the latter company in a cash deal worth $623 million.
