Bis to haul bauxite for Rio Tinto at Gove operations

Bis says it has signed a multi-year bauxite haulage contract with Rio Tinto for its Gove operations in the Northern Territory of Australia.

Bis will deploy an efficient, high payload haulage solution to Gove, enabling a day shift only approach, which will also provide a strong foundation for managing employee attraction, it said.

Bis Chief Executive Officer, Brad Rogers, said the new contract is testament to the company’s focus on innovation and safety.

“I’m very proud we are able to offer a tailored and efficient haulage solution to Rio Tinto in a way that is conducive to a compelling employee value proposition.

“Given the remoteness of the operation – Gove is 1,000 km from Darwin – the ability to meet Rio Tinto’s production requirements in a cost efficient manner, with day shift only operations, will help to deliver a safe and reliable operation. We are excited to commence at Gove and look forward to supporting Rio Tinto at this important operation.”

The haulage and road maintenance contract will see Bis provide off-road haulage of bauxite, road grading, dust suppression and associated support services.

Assets include 230 t haulage combinations, loaders, graders, a water cart and other support equipment. Mobilisation of the new Gove contract begins immediately.

Bis has a long history of providing haulage, material handling and site services in the Northern Territory across a variety of commodities including manganese, iron ore and bauxite, it said.

This latest contract award comes only weeks after the company announced it had also secured a project with new customer, Stanmore Resources, at its Bowen Basin operation in Queensland.

Orica’s 4D bulk explosives tech gains traction in Australia

Having launched its 4D™ bulk explosives technology at MINExpo 2021 in Las Vegas, in September, Orica is now demonstrating the innovation to coal customers on Australia’s East Coast.

The 4D bulk system enables the real-time tailoring of explosives energy to geology across a blast, delivering improvements in fragmentation, on-bench productivity and an overall reduction in drill and blast costs, according to Orica. It is designed to enable customers to, the company says, seamlessly match a greater range of explosives energy across a mine’s geology and target specific blast outcomes in real time.

Back in September, the company said the first release of 4D would begin with Australia from the end of 2021, and it appears Orica has stuck with that schedule.

“We are happy to share that, in Australia, we are currently demonstrating 4D to customers in the East Coast’s coal mines, each with a unique focus to their needs,” the company told IM. “For example, with one customer, we are demonstrating how 4D technology can reduce their overall drill and blast cost through lower explosives consumption, as well as better manage vibration in specific areas of their operation.”

With another customer, Orica is applying the 4D technology to its Fortis™ Clear range of bulk explosive products – formulated for use in applications where the generation of post-blast fume could be experienced – to demonstrate the reduction of fume risk in soft and wet ground, it added.

The technology is also being developed across Orica’s Fortan™ and Aquacharge™ bulk systems but will eventually be applied across Orica’s full suite of bulk systems.

4D is being delivered to these customers through Mobile Manufacturing Units (MMU™) equipped with LOADPlus™, Orica’s proprietary in-cab smart explosives delivery control system that, it says, enables accurate and efficient delivery of formulated explosives products to plan.

By combining emulsion blended with ammonium nitrate porous prills, 4D supports both pumped and augered loading methods across dry, wet and dewatered hole conditions. An outcome of this capability is greater on-bench productivity by Orica’s fleet of 4D-enabled, without the need to change raw materials in the MMU, Orica says.

Delivering up to 23% more relative bulk strength for hard-rock applications and up to 43% reduction in soft-rock applications, 4D will enable a broader range of applications, according to Orica.

Orica said in its half-year results to the end of March 31, 2022 that it was expecting to roll out the 4D technology to more sites in the second half of its financial year.

Rajant and Acubis BreadCrumb solution solves Stanwell Meandu comms issues

Rajant Corporation, the pioneer of Kinetic Mesh® wireless networks, and Acubis Technologies, a Kinetic Mesh Premier Partner in Australia, have delivered what they say is the first FE1 series BreadCrumbs® – Rajant Peregrine and Hawk – at Stanwell’s Meandu mine in Queensland, Australia.

Stanwell was battling the ever-evolving data and application requirements of its operational technology (OT) network, which supports CCTV, access control, in-vehicle fleet management and autonomous haulage, and needed the additional throughput that Peregrine and Hawk provide, Rajant said.

Chris Acton, Acubis General Manager, said: “Stanwell owns Tarong power stations, one of Queensland’s largest electricity-generating sites, and the stations receive coal from the Stanwell-owned Meandu Mine via a conveyor. Dependency on sustained operations and critical infrastructure security are paramount.

“Industrial conditions are harsh and towering ridges surround the mine. Running multiple applications, video streams, real-time data transfer, and edge devices required Rajant for unfailing networking with high throughput and low latency. The Peregrine and Hawk are robust and secure. Moreover, these BreadCrumb radio nodes can grow with the capacity needs for future applications and deliver cost-saving efficiencies to Stanwell’s thermal power production.”

Stanwell’s Manager of Business Improvement and Technology, Julio Romani, said: “The Meandu Technology Roadmap highlighted that a prerequisite for Meandu to accelerate and realise the value provided by technology advances was the establishment of suitable networks and communications platforms. The Rajant Peregrine & Hawk are an integral OT infrastructure component. These BreadCrumb nodes maximise the use of the fleet management system, enable telemetry and high precision GPS technologies, and provide connectivity for CCTV, environmental and control systems that operate across our Rajant wireless network.”

Thiess to trial Plotlogic’s OreSense tech at Anthill copper project

Thiess says it is taking another step to be at the forefront of sustainable mining with a technology trial involving Plotlogic’s OreSense solution at the Anthill copper project in Central Queensland, Australia.

With the promise of reduced environmental impact, improved safety and increased productivity the OreSense technology scans rock to distinguish high-grade resources from waste, Thiess explains. The technology provides real-time information, eliminating the need for a week or more waiting for testing results.

The technology is also expected to create environmental benefits through lower fuel usage and machinery consumables and a more optimised heap leaching process, according to Thiess.

Group Executive Growth & Strategy, Abdul Jarrah, said the trial aligned with Thiess’ commitment to use technology to drive sustainable improvements for our clients.

“Investing in technology such as OreSense further enhances our inhouse capability and allows us to offer our clients greater value across the safety, cost, productivity and environmental spectrum,” Jarrah said. “Importantly, our focus on innovation will support our clients to achieve their environmental goals as Thiess continues to establish itself as a leader in sustainable mining practices.”

Group Manager, Geology and Geotechnical, Donna Sheehy, said applications for the technology were far-reaching.

“The machine takes around three minutes to scan a wall or mine face area of 15 m by 50 m – if the trial proves successful there is potential to scan dig faces and stockpiles to determine grade,” she said.

“From machine learning we can use OreSense to give us real time assay – saving lengthy lab processing wait times.

“This allows us to increase the average grade of material fed to the heap leaching process which means we haul less waste, reducing our use of fuel and machinery consumables.”

The trial, set to begin at the Anthill copper project, owned by Austral Resources, on April 27, will run for around four weeks.

Austral says CSA Global completed an updated mining study in April 2021 on Anthill resulting in a JORC 2012 compliant ore reserve of 5.1 Mt grading 0.94% Cu containing 47,700 t of copper. This study outlined that ore will be mined from two pits over a 40-month period. Total recovered copper from the heap leach process will be 40,400 t over a 44-month period.

Monadelphous Group banks work with Rio, Tronox and Newcrest

Monadelphous Group has announced several new contracts and contract extensions in the resources and energy sectors in Australia and Papua New Guinea, including work with Rio Tinto, Tronox Mining Australia and Newcrest Mining.

RME supplies Northern Star’s Thunderbox mine with 500th Mill Relining Machine

In what it says is a major milestone, Russell Mineral Equipment (RME) has designed and completed production of its 500th Mill Relining Machine (MRM) for Australia-based gold producer Northern Star Resources Ltd.

This custom-made RUSSELL MRM will be accepted by Northern Star at a ceremony at RME’s global headquarters in Toowoomba, Queensland, this month. This MRM will service Northern Star’s new SAG mill at its Thunderbox project in the Goldfields of Western Australia.

RME and Northern Star began their relationship at the Kanowna Belle Operations, some 30 years ago with the purchase of RUSSELL MRM number five (MRM005). Northern Star owns six RUSSELL MRMs, including the 400th RUSSELL MRM, commissioned in 2018 at Kanowna Belle. Thismachine replaced a RUSSELL MRM that had been in operation at Kanowna Belle for 25 years.

The 500th RUSSELL MRM is a RUSSELL 7-axis, 6,000-kg capacity machine. The RUSSELL 7 is RME’s signature model sold globally, and this unit also comes with advanced RME INSIDEOUT™ technologies. These proprietary new technologies, developed by RME, enable placement and removal of grinding mill liners without any crew working on the charge inside the mill, greatly reducing exposure of personnel to significant hazards, the company says.

Since the introduction of the very first RUSSELL 7-axis MRM in 1992, traditional mill relining times have been quartered and many health and safety hazards have been eliminated, RME says.
Chief Customer Officer, Cherylyn Russell, says RME is a proud supplier to the hard-rock mining and mineral processing industry, primarily those processing gold and copper.

“This milestone is a chance to acknowledge the technology and safety advances of the RME Mill Relining System that enable giant grinding mills to get back to work quicker after regular relining,” she said. “Mill relining is the most specialised maintenance task in the mineral concentrator process and often dictates the length of shutdowns. RME’s innovative, customised, robust equipment helps increase mine site profitability, all while improving the safety of the working environment.”

Anglo American commences first longwall shear at Aquila met coal mine

Anglo American’s new Aquila mine has achieved its first longwall shear of steelmaking metallurgical coal on schedule and on budget, marking the project’s final stages of construction and commissioning, it says.

The Aquila mine, located near Middlemount in Central Queensland in Australia, extends the life of Anglo American’s existing Capcoal underground operations by seven years, after the company’s nearby Grasstree mine reached its end of life in recent weeks.

Themba Mkhwanazi, CEO of Bulk Commodities, said: “We have delivered the Aquila project on time and within our budgeted attributable cost of $226 million. This new mine will have a total average annual saleable production of around five million tonnes of premium quality hard coking coal and benefits from low capital intensity as we are using the existing infrastructure and systems from our adjacent operations. Aquila offers us highly attractive returns and margins at conservative long term consensus prices.”

Tyler Mitchelson, CEO of Anglo American’s Metallurgical Coal business, said: “Safely starting up longwall mining at Aquila Mine on our original schedule, despite the effects of the pandemic, is an important milestone for our Metallurgical Coal business and will support our ongoing contribution to both the Middlemount community, and Queensland’s economy. The mine uses our existing infrastructure at our Capcoal complex and supports around 600 ongoing operational roles for our Queensland-based workforce, including providing continuity of employment for our Grasstree mining team.”

The Aquila Mine has been developed as one of Australia’s most technologically advanced underground mines, leveraging Anglo American’s advancements in underground automation technology, remote operations and data analytics, the company says. The mine features two longwalls, allowing operations to continue without the downtime usually required for longwall moves. Both longwalls are fully remote-capable and will be sequentially operated from a site-based remote operations centre on the surface of the mine.

Anglo American’s Capcoal complex comprises Capcoal Open Cut Mine, Grasstree Mine, Aquila Mine, the Coal Handling and Preparation Plant and associated infrastructure. Aquila is owned 70% by Anglo American and 30% by Mitsui & Co. Ltd.

Redpath to carry out raisebore, boxhole services at Kirkland Lake Gold’s Fosterville mine

Redpath Australia says it has commenced a new raisebore contract with Kirkland Lake Gold at the Fosterville gold mine in Bendigo, Victoria.

Under the new contract, Redpath will provide raisebore and boxhole services at the mine through to late 2023.

The contract extends Redpath’s continuous presence at Fosterville to over 10 years.

Fosterville is a high-grade, low-cost underground gold mine, which commenced operation in 2005 and, during its initial years, produced gold from near-surface, low-grade mineralisation. It is now an underground mine with decline access that, last year, produced 509,601 oz of gold.

Redpath’s raiseboring division also has a relationship with the Kirkland Lake team at Macassa. The team completed a 1,010-m-long hole at the mine in Ontario, Canada, in 2021, making it the longest raisebore hole ever accomplished in the Northern Hemisphere and all the Americas when it was carried out.
