“We are very excited to showcase this rig at this year’s MINExpo. The SmartROC D65 BE is a milestone for us and for surface drilling around the world. The fact that we are removing tail pipe emissions from the drilling process is an important step towards a better environment. This accomplishment also shows that Epiroc has a vital role to play in making our industry more sustainable,” says Martin Johansson, Acting Vice President Marketing, Epiroc Surface division.

The SmartROC D65 BE demonstrator is based on the well-proven SmartROC D65 surface drill rig. In combination with invaluable experience gained from the development of Epiroc underground battery rigs, this new rig is designed to enhance the environmental standards of mining and larger quarry sites. Besides the low emissions, this rig provides the same range of on-board smart features, and delivers high safety, reliability, and performance – in a quieter working environment.

“We have seen a demand in the mining business for greener solution – and with SmartROC D65 BE we meet those demands,” says Mattias Hjerpe, Global Product Manager, Epiroc Surface division.

The leading service provider Capital Ltd has been a close partner during the testing phase. The SmartROC D65 BE demonstrator on the stand will also go directly to Capital Ltd for field trial after the exhibition. Capital Ltd points out that SmartROC D65 BE will be an important asset in their future transition journey towards reducing emission and decarbonisation.

“We are excited to be partnering with Epiroc to field test this innovative electric drill rig technology that will help drive our industry towards more sustainable operations. To be at the forefront of the transformation towards emissions-free surface drilling supports our company’s overarching commitment to decarbonisation, as well as providing value for our customers,” says Peter Stokes, Chief Executive Officer Capital Ltd.

The SmartROC D65 BE demonstrator is equipped with a battery which drives the tramming motors and an electric cable to hook it up to provide power for drilling. “The SmartROC D65 BE surface drill rig is fitted with the same type of well-proven batteries and subcomponents as in other Epiroc battery solutions. This streamlines spare parts handling and service for customers with several different operations,” says Hjerpe.

Epiroc says its battery-electric solutions are attracting strong interest from the market. Customer benefits include emissions-free operations, lower noise pollution and vibration, and higher productivity. The rig plays a vital role in Epiroc’s ambitious sustainability goals for 2030, which include halving the CO2 emissions in operations and from sold products when compared to 2019 levels.

In 2021, the goals were validated by the Science Backed Targets initiative as being in line with keeping global warming at a maximum 1.5°C, consistent with the latest climate science and the goal of the Paris Climate Agreement. Epiroc says it is determined to offer its full range of underground equipment in an emission-free version by 2025, and for the surface equipment it aims to offer the same by 2030.

BEUMER Group to showcase digitalisation breakthroughs in mining at MINExpo 2024

BEUMER Group says it will outline the considerable advantages in efficiency, safety, and sustainability of digitalisation in mining at the MINExpo exhibition in Las Vegas, Nevada, from 24 to 26 September 2024.

Visitors to the event can find out how digitalisation can be a catalyst for change. Digitalisation in mining enables organisations to collect and analyse data and to test the machines under new operational conditions, ie using a digital twin model. These unique options enabled by digitalisation lead to a data-driven and more informed decision making process. Mining plants can also benefit from cost reductions and increased efficiencies as digitalisation supports the implementation of material tracking systems. Companies are able to automate and streamline mining processes and closely monitor resources through sensor data providing insights into bulk material handling and transport processes – therefore enabling more intelligent routing.  

Digitalisation can also underpin stockyard management systems, streamlining and automating scheduling, monitoring and documenting material handling and storage for more efficient operations. It can provide the foundation for smart mine connectivity, consolidating data from all machines and equipment into a single front-end dashboard for a wider scope of visibility and the enablement of predictive maintenance scheduling for minimal unexpected downtime. The same digitalisation principles can be applied to other essential mining tasks, such as train loading systems. 

As well as advanced anti-collision systems combining mapping technology, digital mining solutions can improve safety by protecting personnel and assets. It also enhances the remote operation of equipment.   

In addition to these benefits, the effective application of digital solutions can mitigate the workforce retention issues currently facing the mining industry. With an aging workforce leading to a widening skills gap, digitalisation could change how the mining industry approaches tasks that were once thought of as exclusively manual. 

BEUMER Group offers completely tailor-made solutions for digitalisation in mining and bulk material handling, acting as a digital integrator. Its experts will be available at the booth at MINExpo to discuss how digital technologies can blend with existing solutions and processes for commercial advantage.  

Visitors can also discover more about the full package of products and services from bulk materials specialist FAM Minerals & Mining, part of BEUMER Group since 2022. FAM offers machines along the complete transport chain for bulk materials, from the pit, to the plant, to the port, including extraction, conveying, processing, storage, loading and unloading of various raw materials. It provides end users with a comprehensive service, including development of customised technical solutions, detailed planning, delivery, installation, commissioning and maintenance of the machines. Experts will be on hand to discuss how implementing digitalisation can enhance FAM’s portfolio of products and services. 

“Digitalisation is a term most often associated with smart factories, but it can also have a transformative effect on heavy industries like mining,” says Bruno Castro, Global Head of Digital Technology, Minerals & Mining at BEUMER Group. “Our experts can help the mining industry realise the tangible benefits of digitalisation to improve efficiency, productivity and safety. We’re looking forward to welcoming visitors to our booth during MINExpo to discuss how best to unlock the power of digital technologies.”

Feasibility study on Lumwana Super Pit expansion expected by year-end

The feasibility study for the expansion of Barrick’s Lumwana mine in Zambia is expected to be completed by the end of the year, paving the way for construction to start in 2025, the company said today.

Speaking during a webinar focused on updating the market on the Lumwana Super Pit Expansion Project, Barrick President and Chief Executive Mark Bristow said the expansion unlocks the potential to transform the Lumwana mine into a long-life, high yielding, Top 25 copper producer and a Tier 1 copper mine, capable of contending with the volatility of the copper demand cycles.

The expansion involves first doubling throughput by twinning the existing process circuit and then by significantly increasing mining volumes. Plant throughput will grow from the current 27 Mt to 52 Mt, doubling the mine’s annual copper production from 120,000 t to a life-of-mine average of 240,000 t per annum. The process expansion is supported by a ramp up of total mining volumes, which are planned to increase incrementally year-on-year, from 150 Mt in 2024 to approximately 240 Mt in 2028 and then to an average rate of 290 Mt per annum from 2030 onwards.

Chief Operating Officer for Africa and Middle East Sebastiaan Bock said: “The phased ramp-up will enable a competitive cost profile over the life of the mine and annual operating cash flow and free cash flow are projected to improve by as much as 85% and 60%, respectively, based on the long-term copper price consensus. These production and cost improvements will contribute to an estimated incremental net present value (NPV8) of $1.7 billion.”

At a flat long term average copper price consensus of $4.13/lb, Barrick estimates that the project will deliver an incremental IRR (Internal Rate of Return) of 20% and a total mine IRR of more than 50%, paying back the initial expansion capital in approximately two years after completion of the expansion. Post-expansion, cost of sales and C1 cash costs are estimated at approximately $2.36/lb and $1.85/lb, respectively, placing Lumwana in the first quartile of the industry, excluding the benefit of any byproducts.

Barrick says the plant expansion design is modern, efficient and fit for purpose – building on the existing operational knowledge base with a design underpinned by geometallurgical test work and its advanced orebody knowledge. Thorough comminution and flotation testwork has been completed on the mined Lumwana deposits and new satellites.

It also has expanded footprint synergises with the existing process plant infrastructure, plus learnings from the feasibility study have been applied to upgrades on the existing process plant to increase use of technology to improve efficiency and delivery. The expansion will see improvements in process control and automation alongside the experience of world-class operators from the current plant.

According to Mineral Resource Management and Evaluation Executive Simon Bottoms, the process plant engineering has matured to a point that has allowed Barrick to select major equipment vendors and place orders for long lead equipment, including both mills and crushers. “We are starting detailed engineering works this quarter and expanding our onsite accommodation while building partnerships with key suppliers and contractors ahead of the pre-construction ground preparation works, which are scheduled to start next year,” said Bottoms.

Commissioning of the new process plant is planned to start in the second half of 2027. Once the new process circuit is commissioned, the existing circuit will undergo a series of planned shutdowns, allowing Barrick to install upgrades, while ensuring uninterrupted copper delivery throughout the expansion.

The permitting process for the expansion is well underway, with the Environmental and Social Impact Assessment already submitted to the Zambian authorities and approval expected by the end of this year.

Regarding the mining equipment, new Komatsu 930E-5 trucks along with Hitachi EH5000 trucks now make up the fleet teamed with Komatsu PC8000 and PC7000 shovels, with Barrick stating that it has optimised the fleet for the ramp-up based on past experience. A phased transition to cable electric-powered shovels is set to be complete in 2031; while in-pit crushing and conveying has been built into the mine design to reduce truck requirements.

Codelco’s Radomiro Tomic division adds 65 electric buses

In the presence of Rubén Alvarado, Executive President of Codelco; Gabriel Méndez, Vice President of Corporate Affairs and Sustainability; Julio Díaz, General Manager of the Radomiro Tomic Division (DRT), in addition to union leaders and a delegation of students from the Radomiro Tomic Romero B-34 High School in Calama, Codelco has inaugurated a fleet of 65 100% electric buses at DRT, which is the largest in northern Chile.

This initiative will benefit 800 workers daily, a number that will increase as collaborators from contracting companies join. These 65 new vehicles have been added to the existing electric buses at the Codelco El Teniente, Andina, Salvador and Chuquicamata divisions, with the company-wide fleet now totalling 250 units.

The electric fleet represents an important step towards sustainability and care for the environment, since it will reduce carbon dioxide (CO2) emissions into the atmosphere by around 40 tons per year per unit, which is a contribution to the corporate principles of ‘Deliver with excellence and innovation’ and ‘Build the future with sustainability,’ as reflected in Codelco’s Charter of Values.

“We have 250 electric buses in the company, which make up the largest fleet of this equipment in national mining and it is part of making our purpose a reality: we want to be a pillar of the sustainable development of Chile and the world,” emphasised Alvarado. He delved into the initiatives that constitute key elements in this regard. “The fact that the students of the Radomiro Tomic Romero High School are present, and that we are inaugurating these buses concerned about our own carbon footprint and how we integrate with the communities is, finally, sustainable development and what we are trying to promote in Codelco.”

For his part, Julio Díaz described overall progress at DRT in terms of sustainability. “We are fully entering the era of electromobility with these 65 buses. Also in 2026, contracts with 100% renewable energy will be incorporated and the first cubic metres of desalinated water will arrive. The way we are going to operate in the division has to live up to the best sustainability standards.”

The activity also included the participation of workers and the companies Buses JM, the bus operator; charging station and electrical infrastructure provider Enel X; and Cabal, representatives of the Chinese electric bus manufacturer Zhongtong in Chile.

Aya Gold & Silver updates on Zgounder expansion project progress

Aya Gold & Silver Inc recently provided an update on construction progress at its Zgounder Silver Mine in the Kingdom of Morocco. The expansion project was 98% complete as at August 30, fully funded, and on budget.

However, engineering, procurement, and construction partner, Duro Felguera (DF), encountered issues during commissioning of the hydraulic unit of the ball mill. As a result of these issues, DF recently advised Aya that a rework of the hydraulic unit piping is required. This does not impact the integrity of the ball mill, the hydraulic unit or other equipment. Commissioning of other subsystems is proceeding steadily, and the crushing circuit is now operational.

As a result of the necessary rework, DF has requested and obtained from Aya a two-month extension for hot commissioning and ramp-up of the Zgounder expanded plant. All other critical areas of the Zgounder expansion project are progressing to plan or are in commissioning:

Commissioning of other areas of the plant continues to progress: ore has been crushed throughout the entire crushing circuit and sent to the silo. Work has begun on the underground ramp from the 1,925 m to 1,900 m levels and will continue to lower levels. The entire mining site is now powered with renewable energy from the newly built 60 kV power line plus the new underground mobile workshop is in use and the primary underground ventilation is working on all levels. The on-surface cemented backfill mixing station and piping on all sublevels are mechanically complete and will shortly be commissioned.

All four underground electrical substations have been deployed and the water dams and other water storage infrastructures are operational. The new tailings dam is in use and water is being recovered from the tailing dam. The base camp is also complete and the new assay laboratory is near-complete with commissioning planned end of September 2024.

Given the delay in hot-commissioning and ramp-up of the Zgounder expanded plant, the company’s 2024 production guidance is under review. Aya expects to revisit its production guidance based on construction progress and operational results by latest November 14, 2024, when it will publish its third-quarter 2024 financial results.

“While there has been a slight delay in hot commissioning, all critical aspects of the Zgounder Mine expansion are advancing as planned, and the project remains on budget,” said Benoit La Salle, President & CEO. “We are on track for a strong finish to the year with additional operational milestones and exploration drill results expected to further enhance stakeholder value. We are confident that 2025 will be an exceptional year following completion of the plant ramp-up.”

Newmont selling Telfer and Haverion assets to Greatland Gold

Newmont Corporation has announced today, as part of its ongoing program to divest non-core assets, it has agreed to sell the Telfer operation, Newmont’s 70% interest in the Havieron gold-copper project, and other related interests in the Paterson region, all in Australia, to Greatland Gold PLC.
