Rio Tinto has today completed the acquisition of Pan American Silver’s stake in Agua de la Falda and entered a joint venture with Corporación Nacional del Cobre de Chile (Codelco) to explore and potentially develop the company’s assets in Chile’s prospective Atacama region.

The acquisition, announced on August 1, 2023, comprises a 57.74% operating stake in Agua de la Falda for $45 million and the grant of net smelter returns royalties. It paves the way for Rio Tinto and Codelco to start its joint exploration project at the asset.

Jakob Stausholm (left), Rio Tinto Chief Executive, and Maximo Pacheco (right), Chairman, Codelco, today met in Tokyo to formalise the new joint venture, which will be known as Nuevo Cobre (New Copper).

Stausholm said: “Chile is one of the most important sources of the copper and other critical minerals the world needs to deliver the energy transition and achieve net zero. With this partnership, we are bringing together our complementary experience and capabilities. Codelco’s local knowledge and expertise is second to none and we have a global track record in exploration. I am very much looking forward to getting our work on the ground started.”

Pacheco said: “This is an unbeatable opportunity for Codelco and Rio Tinto to join our knowledge, experience, strengths and capabilities to accelerate exploration and development of these assets to contribute the copper that the world needs for its energy transition. We are very pleased to formalise this partnership with Rio Tinto and acknowledge our mutual commitment to following the best standards of health, safety, community relations and care for the environment.”

Agua de la Falda has previously been explored for precious metals with minimal modern exploration for copper. Analysis by Rio Tinto Exploration indicates it is prospective for new copper discoveries, which will now be the focus of the joint venture.

The partnership builds on a collaboration agreement between the two companies signed in October 2022, aimed at encouraging innovations and technology to improve safety, productivity and environmental, social and governance outcomes in underground mining.

Elebbre uses Krank auction tech to remarket Bechtel mining, construction equipment in Chile

Equipment maintenance, Mining equipment, Mining services, , , , , , ,

Global engineering, procurement and construction company Bechtel has chosen Latin American equipment remarketing experts Elebbre to manage an auction of its equipment from a major mines’ expansion and desalination plant construction – all underpinned by the latest auction technology from Krank.

The expansion of the world’s largest copper mine in northern Chile has prompted a renewal of a proportion of the mobile fleet based there, resulting in a surplus of used construction equipment for the mines’ expansion operators. The task of managing the sale of equipment such as dump trucks, boom trucks and cranes for one of the world’s top five construction companies – Bechtel – has fallen to Latin American equipment experts Elebbre.

The sale of the machines is to be by auction with Elebbre adopting the latest online marketplace platform from UK-based SaaS provider Krank. Using the Krank platform means Elebbre can manage the entire auction and sale process itself, rather than having to rely on the support of third-party auction houses.

The platform connects construction and mining industry peers by providing a solution for building networks and connections, via which new and used equipment can be remarketed. Its platform is being used by major equipment OEMs, rental companies and others with equipment fleets, and gives users access to a network of high-intent buyers, which helps to convert into sales faster, with reduced costs and improved revenues, according to Krank.

Elebbre’s co-Founder and General Manager, Moisés Nunez, said: “The Krank platform has been customised to our needs and provides a seamless trading experience for ourselves as sellers, and for our buyers. It will be a key component in achieving favourable market prices for these assets, maximising transparency in the negotiation process and accurately valuing assets, via certified inspection methodologies and reporting.”

Krank founder and CEO, Mark Turner, said: “Elebbre has a strong reputation for using the most innovative thinking for the commercialisation of equipment in Latin America; combining technology with extensive experience in the mining, agriculture and transport sectors. It’s therefore no surprise that such a globally respected mining support giant such as Bechtel has entrusted the sale of its equipment to Elebbre. Adding in our platform to this mix allows Elebbre to independently trade heavy equipment under its own brand, run its own timed and live video auctions and facilitate greater customer engagement.”

Multotec expands Brazilian presence with new manufacturing facility

Multotec has recently expanded its operation in Brazil with the opening of a manufacturing facility that, it says, enables the company to bring its manufacturing capabilities closer to its customers in the country, increasing its speed to market and enabling it to better serve the local mining sector.

Located in the city of Contagem, in the south-eastern state of Minas Gerais, the manufacturing facility is within close proximity of a multitude of iron ore mines that require an extensive range of mineral processing equipment for their plants.

Multotec Brazil Country Manager, Anthony Artin, explains that with Brazil being the world’s second-largest iron ore producer, Multotec had identified the country as a potential area of growth many years ago.

Artin says that, initially, Multotec Chile was overseeing the full South American region, with the company deciding to open a sales office in Brazil in 2019, giving focused service to Multotec’s customers here.

“The dynamics of Brazil are very unique as it is the fifth biggest country in the world, with the sixth largest population,” Artin says. “It has strict and complex import regulations.”

The feedback from clients emphasised the importance of localised sales and manufacturing in Brazil, according to Artin. Commercial and legislative requirements prompted a shift in Multotec’s approach, transitioning from a sales office to establishing a manufacturing facility in the country.

He said: “Our clients highlighted the significance of Brazil for Brazilians, emphasising the need for local manufacturing facilities to cater to the Brazilian market.”

The new facility focuses strongly on screening media, using compression moulding for the production of rubber screen panels and also hand-casting polyurethane (PU) panels. However, customers are increasingly requesting other products too, such as samplers and spirals that are used in mineral processing and separation.

“There are currently two bays in the manufacturing facility,” Artin says. “One is used for stockholding, assemblies and shipping, while the other is used for fabrication. Fabrication is done in two areas, with presses used for compression moulding of rubber and hand-casting moulding PU tables, alongside a PU preparation section and ovens.”

Artin notes that the facility has the capacity to produce 15-20 t/mth of elastomers and employs trained people in manufacturing and in stores, shipping and receiving. Plans are in place to increase the factory’s manufacturing capability in terms of injection moulding and more compression moulding, he said, adding that more machines will be incorporated into the operations – resulting in more people being employed in the future.

In addition, the premises also contain an office currently staffed by commercial, sales and administrative people. Having the office and manufacturing facility in one location is an added advantage, according to Artin. “It is beneficial having the people who sell the products located in the same space production,” he says. “They can thus understand the intricacies of the product and the processes that are involved in the manufacturing of the equipment.

“The ultimate goal is to have a fully localised branch. We want to have an all-Brazilian team, working for Multotec Brazil. Local partners and suppliers are key to us as we rely on local raw materials to deliver completely locally manufactured products.”

While the company’s focus has been on establishing the manufacturing facility, Artin says it has already applied for an extension of its environmental licence to ramp up its monthly production as it takes advantage of Brazil’s current lithium boom, which presents considerable opportunities in dense medium circuits.

Multotec Brazil will receive support from Multotec’s global industry knowledge and expertise, leading to enhanced operational efficiencies and providing customers with comprehensive solutions over and above a quality product offering, the company says. Furthermore, Brazil will collaborate closely with Chile on the Multotec range of customised samplers. With input from Chile and local manufacturing in Brazil, this collaboration will create a seamless workflow that maximises efficiency, ensuring the delivery of high-quality samplers tailored to the specific requirements of customers, it concluded.

TORSUS reinforces off-road bus offering for mining companies

Mining equipment, Mining safety, , , , , , , , , , , , , ,

Armed with a remit of building vehicles for the world’s toughest jobs, TORSUS is looking to bridge the gap between off-highway personnel carriers and on-highway buses in the mining industry.

Having only entered this territory in 2017 with the launch of its first-generation PRAETORIAN off-road bus for a maximum of 35 people (including the driver), TORSUS is a relative newcomer, but it is adapting quickly to the whims of modern-day mining companies.

TORSUS leverages off its parent company, Pulsar Expo s.r.o, a Czech Republic-based entity with production facilities in Slovakia, while having partnerships in place with MAN and Volkswagen on key chassis and powertrain technology.

Vakhtang Dzhukashvili, CEO of TORSUS, explains how this combination results in a unique offering.

“We have come up with a product to meet the needs of the market by offering a standard all-terrain MAN chassis on our vehicles and robust Volkswagen powertrains with all the customisation options you need to make it robust, as well as comfortable for transporting personnel,” he said.

In terms of suspension, the PRAETORIAN, which was updated in 2021, benefits from leaf-spring with differential lock suspension on the front axle and air suspended suspension on the rear axle. It also has Michelin XZL 365/80 R20 tyres, two “comfort options” for seats, ground clearance of up to 400 mm and military-grade elastomeric panels. These are accompanied by a drivetrain warranty of up to six years, or 900,000 km, and a whole vehicle warranty of two years without mile limitation.

The PRAETORIAN off-road bus can transport a maximum of 35 people (including the driver)

These 2.54-m-wide by 8.7-m-long vehicles have been proven in tourism transport applications taking people up Mount Etna in Italy – aided by a MAN six-cylinder diesel engine with 286 hp (213 kW) of power and 1,150 Nm of torque, as well as a heavy-duty 4×4 off-road transmission. This specification, in fact, means it can go up inclines as high as 65%.

Mining, defence and tourism are TORSUS’ major markets, each holding around 33% market share, according to Dzhukashvili.

“In mining, the PRAETORIAN presents a new option for companies looking to transport personnel on scale to site,” he says. “Instead of using multiple off-road personnel carriers to transport people to and from the off-grid mine site or – the other option – developing paved roads earlier in the development process, we can offer something to bridge the gap.”

One can imagine multi-mine operators in West Africa, for example, making the most of this by leveraging vehicles to transport personnel to site depending on the stage of development. The vehicle – which can also drive on-road – could then move to another site after paved roads are established.

Companies looking to transport fewer people to off-road operations may be interested in the TORSUS TERRASTORM. This vehicle has the same robust ideologies of the PRAETORIAN, but is equipped to transport up to 17 people (including the driver).

Both these vehicles have won admirers in the mining sector, with units already stationed at operations in Chile, Gabon, Ghana, Mali and Papua New Guinea.

Dzhukashvili expects more mining deployments in the future, as the wider industry acknowledges the niche the company is serving.

“With the backing of MAN and VW, and the ability to deliver customised options in-house, we have all the components needed to make these off-road buses robust, comfortable and long lasting,” he said. “Add to that worldwide support from the MAN and VW network, plus our own dealership base, and we’re convinced no-one can offer what we offer the mining business.”

Chile-focused copper miner Sociedad Punta del Cobre S.A (Pucobre) has selected Sandvik Mining and Rock Solutions to supply a fleet of six Toro™ LH621i autonomous loaders equipped with AutoMine® Multi-Lite for its mining operations in northern Chile’s Atacama region, the OEM says.

Pucobre is among Chile’s largest underground copper miners, producing approximately 38,000 t/y of fine copper from its three mines near the northern city of Copiapó.

“We’re consistently exploring and implementing technologies that can enhance safety and productivity in our mines,” Sebastian Rios, Chief Executive Officer at Pucobre, said. “We have an ambitious goal to automate 75% of our stope operations, and this is a major milestone in that journey.”

Sandvik will supply the order in two phases. During 2023, Pucobre will receive four Toro LH621i loaders and the remaining two in 2024.

“We are pleased to support Pucobre in improving the safety, productivity and reliability of its mine operations with the deployment of our autonomous loaders,” Ricardo Pachon, Vice President, Sales South Cone and Andean at Sandvik Mining and Rock Solutions, said. “We look forward to working with Pucobre as it continues on its automation journey.”

Toro LH621i loaders feature a 21-t payload capacity. The loaders’ reliability, robust structure and Sandvik Intelligent Control System enable the use of highly advanced digital solutions, such as AutoMine. The Toro LH621i offers superior hydraulic power for fast bucket filling and drivetrain power for high ramp speeds and can quickly clear tunnel headings for rapid advance rates, according to Sandvik. Long-life components, specifically developed for the rough underground environment, contribute to low cost per tonne.

The AutoMine Multi-Lite system is a highly advanced automation system that enables system operators to remotely and simultaneously supervise multiple automated Sandvik underground loaders and trucks. It provides a powerful way to take advantage of the full machine performance, and helps improve productivity, safety and cost efficiency in underground mining operations, according to the company.

Orexplore Technologies Limited, a mineral scanning technology company focused on the global mining and metals sector, says it has entered the South American market with a commercial field deployment for Gold Fields at its’ Salares Norte project in Chile.

Salares Norte is a high-grade, epithermal gold-silver, open-pit deposit in the High Andes, Atacama Region, of northern Chile , and will be Gold Field’s second mine in South America, joining Cerro Corona in Peru.

Under this agreement, valued at approximately A$430,000 ($285,369), Orexplore will deliver site-based scanning and analysis of around 3,000 m of drilled core for the exploration team.

Orexplore says it will roll-out its new “Smart Sampler” software solution to enable the exploration team to reduce the quantity of drill core that is sent for analysis through assay laboratories. The company will also work collaboratively with the Gold Fields’ site and corporate teams to integrate the broader suite of new Orexplore solutions offered through the technology platform to advance Gold Fields’ orebody knowledge.

Orexplore has designed and is manufacturing a containerised deployment solution tailored to site conditions through local suppliers in Santiago, suitable as a solution across similar South American sites.

Two GeoCore X10® units will be deployed in the container, and Orexplore’s engineering team will attend site to undertake the commissioning and initial start-up of the units. Geoscience and technical personnel will deliver training to Gold Field’s geologists and technicians enabling them to self-operate the GeoCore X10 units in a dry hire style arrangement. Orexplore will provide systems technicians, scanning trainers and a project geologist to ensure ongoing operational and value delivery assurance.

Orexplore’s new Santiago office is being established to meet the expected demand as a result of the sales and business development efforts in the region that continue to identify ongoing annual drill campaigns and large-scale core farms across multiple countries, that are suitable to the technology, it said. As demonstrated through the Perth and Stockholm laboratories, this enables an effective and efficient onboarding process as customers send initial quantities of core to establish trust in the technology and delivery team.

Orexplore’s technology platform comprises its field sensing GeoCore X10® hardware unit that rapidly scans drilled core in less than 15 minutes per metre, and presents the information as a 3D digital model through the company’s Orexplore Insight® software. This platform, the company says, enables remote mining and geology personnel located anywhere in the world to analyse and interpret these 3D core scans, and connect the information into their standard geological software packages to assess orebodies and rapidly study the optimal methods of extraction.

Orexplore says: “This technology is unique through its ability to see through the entire inside of the core using medical grade CT scanners, and to combine this with dual XRF sensors to build three-dimensional elemental and geochemical models that drive powerful automated data-science solutions.

“As one of the few true “deep tech” companies with capabilities spanning from sensor manufacture to data-science and geo-science, Orexplore can provide rapid “sense to decide” solutions that the myriad of geoscience-only companies utilising common third-party sensed data can’t.”

Orexplore’s Managing Director, Brett Giroud, commented: “We are very pleased to be working with Gold Field’s as our first step into the South American region, and to further demonstrate the broad application of our technology platform through our first deployment that targets full integration into an operating mine’s processes and workflows.

“South America is a very large base metals and gold market, with a proven appetite for technology adoption that we believe is well suited to our transformational technology platform. We are excited about the engagement we are seeing in the region and the excellent opportunity this represents for Orexplore going forward.”

He added: “As a business, we remain laser focused on the commercialisation of our technology platform by driving market adoption of our suite of solutions across the mining value chain. Coupled with the Exploration and Resource to Reserve (R2R) solution deployments over the last 12 months, this agreement further demonstrates the breadth and depth of the technology’s market potential and its accelerating global traction.

“In addition to this, and other recent commercial field deployments, Orexplore is rapidly developing additional solutions including ore sorting, and ESG products such as acid-rock drainage and site based environmental monitoring. Working with Tier 1 and other customers through our laboratories, these solutions are advancing rapidly to target customer demands and drive future potential global site deployments.” x

Gold Field’s Vice President of Exploration for the Americas region, Diego Huete, said: “We are very pleased to be commencing this journey with a company as committed to transforming the industry as Orexplore. Working closely with their team, we can see the value creation on offer through this technology from sample optimisation through to Orebody knowledge and ESG solutions, and we are excited by the opportunity that being a first-mover in the digital transformation of mining provides to our business.”

Jetti Resources to deploy catalytic leaching tech at Freeport-operated El Abra

Jetti Resources has reached an agreement with Sociedad Contractual Minera El Abra and Freeport-McMoRan to deploy Jetti’s leaching technology at the El Abra copper mine in Chile, majority-owned and operated by Freeport.

The use of Jetti’s technology will enable El Abra to produce more copper while taking advantage of existing infrastructure and will generate strong financial returns, according to Jetti.

This is not the first Freeport installation for Jetti, with a spokesperson for the mining company recently confirming to IM it was trialling the technology through “a commercial installation” at its Bagdad mine in Arizona, USA.

Jetti’s catalytic technology will be deployed on the existing leach stockpiles at El Abra and will target over 20 MIb/y (9,072 t/y) of incremental copper cathode production after an initial ramp-up period. The project will leverage existing El Abra infrastructure including excess tankhouse capacity sufficient to process all production from Jetti’s leaching technology. Engineering work for the establishment of Jetti’s on-site catalyst facility is already well advanced, with construction expected to commence in the first half of 2023 and commissioning expected in the second half of the year, Jetti said.

El Abra is an open-pit copper mining complex with a large sulphide resource as well as an established leaching operation. In 2022, El Abra produced approximately 200 MIb of copper.

Mike Outwin, CEO and Co-Founder of Jetti Resources, said: “El Abra is Jetti’s first deployment in Chile, and we are delighted to extend our partnership with Freeport to a second site. Real momentum is building behind the deployment of Jetti’s technology as its unique technological, commercial and environmental benefits become increasingly clear. We look forward to working with Freeport to successfully unlock profitable new pounds of copper with a low carbon footprint and with reduced water consumption.”

Krajete looks to test out NOx recovery tech in Chile’s copper space

Base metals, Environmental, Mining industry recognition, Sustainable mining, , , , ,

Krajete GmbH’s nitrogen oxide emission recovery technology is now being tested for use in copper extraction in Chile’s Atacama Desert, the Austria-based company says.

The technology, developed by Krajete and perfected in collaboration with Audi AG, was recently discovered by technology scouts from one of the world’s largest mining groups, it says. The group focuses on the recovery of nitrogen oxides (NOx) produced during copper mining and the further use for valuable materials.

Krajete’s zeolite-based process offers the optimal solution here and will now be tested in a first test plant, the company said.

The extraction of copper from mineral ores is accompanied by the emission of large quantities of NOx, but Krajete believes it can turn these gases into valuable raw materials.

The company, which specialises in the development of sustainable solutions for gas extraction and purification, optimises natural processes for use in industry. For example, it succeeded in developing a zeolite-based way to remove NOx from emission gases. Together with Germany-based Audi AG, this technology has been optimised for use on internal combustion engines in recent years.

Dr Alexander Krajete, CEO and Founder of Krajete GmbH, said: “In fact, our process is so flexible to use that we can adapt it to other – even large-scale industrial – requirements with little effort.”

Krajete continued: “Our process…not only allows NOx to be filtered out of gas emissions, but even the recovery and concentration of these raw materials, which can then serve as a starting point for other valuable materials such as nitric acid.”

The principle of the Krajete technology is the physical binding of NOx to a specially prepared zeolite matrix. From this, the gases filtered out can then be recovered cheaply and easily in concentrated form.

“And the best thing about it is that the zeolite survives this process completely undamaged and can be used again,” Krajete says. “It’s a sustainable principle that turns waste gases into valuable materials.”

The mining company’s technology scouts looked at a significant number of companies for solutions for sustainable recovery of the NOx emitted during copper extraction, according to Krajete, before settling on the solution the Austria-based company is pioneering.

If the process proves successful in this setting, large plants are already being discussed for NOx recovery in copper production. Structures measuring 14 sq.km could be erected that would serve solely to recover the NOx.
