E-Tech evaluating Novamera’s surgical mining technologies for Eureka project

E-Tech Resources Inc has signed a Memorandum of Understanding (MoU) with Novamera Inc to evaluate the use of surgical mining and Novamera’s technologies as the extraction method for its Eureka project in Namibia.

The MoU sets out a series of milestones that include a conceptual surgical mining economic desktop evaluation (commencing immediately), Guidance Tool calibration activities and a bulk sample. The parties are planning to initiate these activities over the next 12 months.

The solution could provide a more cost-effective and faster path to production, while also radically reducing environmental and social impact, E-Tech says. It aligns well with E-Tech’s values of being a sustainable and responsible company with the goal of supporting the green energy transition.

The Eureka project focuses on two rare earth elements (REEs), neodymium and praseodymium. The project’s mineralogy, processability and favourable logistics have the potential to make it one of the simplest and most accessible sources of REE supply to the global market, according to the company.

Todd Burlingame, E-Tech CEO, said: “E-Tech is advancing the development of the Eureka deposit by utilising innovative and leading-edge technology. The minerals of the future will require techniques and approaches that are in line with the ESG principles of their end use. We believe that Novamera’s technologies are revolutionary and E-Tech is thrilled to be at the forefront of exploring new mining methods.

“We are committed to finding sustainable and cost-efficient ways to mine the materials essential for building a low carbon economy, while also protecting and preserving the environment.”

Dustin Angelo, Novamera CEO, said: “We are excited to be working with E-Tech and demonstrating the capabilities of our surgical mining technologies. Mining companies like E-Tech are looking for solutions to bring deposits into production with a smaller environmental footprint than that of conventional mining methods. The willingness to look at a different business model will open more strategic options to generate value for their shareholders and realise positive cash flow sooner for a project.”

Novamera’s proprietary hardware and software seamlessly combine with conventional drilling equipment, allowing mining companies to surgically extract deposits while minimising dilution, according to the company. Real-time data, machine learning and production analytics drive the ‘surgical mining cycle’ to make extraction of complex, narrow-vein deposits not only viable but highly profitable.

A low capital expenditure solution requiring minimal mine development, surgical mining presents miners with a flexible, scalable mining method that can help get into ore quickly with small-scale deposits, it says.

Working together with conventional drilling equipment and operations, the solution generates circa-95% less waste and less than half the greenhouse gas emissions of selective mining methods, according to Novamera. In addition, a closed-loop system is employed to minimise water discharge and real-time backfilling reduces environmental impact and tailings storage needs.

A 2021 proof of concept was designed to test the entire surgical mining system and process, which is made up of three steps. This includes drilling a hole with a standard NQ-sized diamond core rig and sending Novamera’s proprietary guidance tool down through the core barrel on wireline to image the orebody in high resolution and with close spacing; bringing in a large-diameter drill, coupled with the company’s course correction device and positioning control system, to drill to depth following the trajectory provided by the guidance tool and transporting the cuttings using reverse circulation air-lift assist; and backfilling the holes thereafter.

The latest in-field demonstration, completed in late 2022, took place in Baie Verte, Newfoundland, at the same Signal Gold-owned site (the Romeo and Juliet deposit). The trial highlighted the technical capabilities of the guidance tool, the operational impact of real-time data in a production setting and the economic potential of surgical mining, according to Novamera.

Carried out under the auspices of the Canada Mining Innovation Council (CMIC), the demonstration highlighted to the sponsors – OZ Minerals, Vale and an unnamed global gold producer among them – that the guidance tool was integral to effective surgical mining.

In terms of the next steps for the technologies, Angelo told IM back in June that the company was keen to fabricate a “course correction device” able to compensate for the impacts of gravity on drilling such holes and the rock dynamics at play, equip the drill rig with a 2-m-diameter cutting head (as opposed to the 1-m-diameter head used in the proof of concept), prove out the guidance tool at a number of sites to build up a “geological database” and then get to a full production test at a chosen mine site.

Such a mine site test was confirmed around this time after the Government of Canada announced the 24 recipients of support selected through the Mining Innovation Commercialization Accelerator (MICA) Network’s second call for proposals. Novamera was named within this select pool, with the government granting it C$850,005 ($643,984) for a project to deploy its surgical mining technologies at the Hammerdown mine site, in Newfoundland, Canada, a site owned by Maritime Resources.

Appian Capital to take on Rosh Pinah zinc-lead mine in Namibia

Appian Capital Advisory LLP, the investment advisor to long-term value-focused private capital funds that invest in mining and mining-related companies, has acquired an 89.96% interest in the producing Rosh Pinah zinc mine, in the Kharas region in southern Namibia, from Trevali Mining Corporation.

Rosh Pinah is an operating underground zinc-lead mine with a 2,000 t/d milling operation, which has plans in place – via the Rosh Pinah 2.0 mine expansion project – to nearly double the mine’s annual ore throughput to 1.3 Mt and improve safety and environmental performance. The mine has been in continuous operation since 1969, producing zinc and lead sulphide concentrates, as well as smaller amounts of copper, silver and gold.

Appian says it will retain the existing site management team and workforce, who have substantive technical expertise and understanding of the asset.

Michael W Scherb, founder and CEO of Appian, said: “This acquisition marks a significant milestone for Appian as we continue to develop our world-class portfolio of highly attractive zinc assets, a critical metal that will help facilitate the upcoming energy transition. We look forward to welcoming the 450 employees at Rosh Pinah to Appian as we utilise our extensive operational and project development expertise to support the existing management team with delivering the Rosh Pinah 2.0 expansion project. We extend our gratitude to the Namibian government, our valued partners, and the local community for their trust and support.”

The Rosh Pinah 2.0 expansion project envisages the construction of new processing facilities, including the addition of a paste fill and water treatment plant, as well as a dedicated portal and decline to extended deposits. The project will increase mill throughput from 700,000 t/y to 1.3 Mt/y, increasing zinc equivalent production to 170 MIb/y (31,751 t/y), on average.

Trevali, the former 89.96% owner of Rosh Pinah, said previously that the expansion could also lead to the introduction of battery-electric vehicles at the mine.

Rosh Pinah is one of three recent investments by Appian in the zinc market, with the other two being Vedra Metals in Italy and Pine Point in Canada. It did not disclose the acquisition price for the stake in Rosh Pinah.

Sandvik Leopard DI650i drill rigs make first appearance in Namibia mining industry

Namibia-based KODO Drilling has taken delivery of the country’s first Sandvik Mining and Rock Solution’s Leopard™ DI650i surface drill rigs, which are set to go to work at an open-pit gold mine.

The rigs will be used as part of KODO Drilling’s down-the-hole (DTH) production drilling remit at the mine. The units arrived at the mine site in early November 2022.

According to Andries van Wyngaard, Territory Manager and Acting Managing Director at Sandvik Namibia, the contract is an important step in the company’s expansion strategy. Over the past year, its field service department has grown to seven trained full-service technicians in-country.

“As Sandvik Namibia gears up to support more equipment sales into the local market, we are grateful to KODO Drilling for their confidence in our innovative products and committed service,” van Wyngaard says. “With the values of KODO Drilling and Sandvik Mining and Rock Solutions so closely aligned – including safety and service excellence – this is a perfect fit.”

The DI650i, a diesel powered crawler mounted intelligent DTH rig, is designed for demanding production drilling applications in surface mining, according to van Wyngaard. The self-contained unit is equipped with an ergonomic iCAB operator’s cabin, fixed boom, dry dust collector and drill pipe changer – incorporating a modern design and layout.

“The rig comes with a range of new or redesigned components to boost its productivity,” he says. “It has the capacity to drill a wide variety of hole sizes from 90-165 mm. We have also run trials in Namibia with our RH560 hammer and we’ve seen exceptional performance – drilling holes from 115-203 mm.”

KODO Drilling Director, Vilho Hanghome, says his company’s progress is based on its constant drive to deliver innovative services and perform within a safe and environmentally sustainable manner.

“Having previously procured exploration rigs from Sandvik, we have valued the equipment quality and service we have received – as these have allowed us to deliver performance within budget to our clients,” Hanghome says. “We are therefore pleased to be investing in Sandvik’s state-of-the-art DTH technology and we will rely on their high level technical support going forward.”

Van Wyngaard says the contract shows KODO’s faith in Sandvik Namibia’s ability to support its DTH offering with aftermarket service. He points to the considerable interest the local market has shown in the delivery of the two rigs.

“After we signed off on the deal and sent the units off from our Khomanani headquarters in Kempton Park, many of our Namibian customers have noticed them on the road and posted excited comments online,” he says. “The mine where the rigs will operate is also looking forward to benefiting from the results of the new machines’ performance.”

Among the advantages the units offer is ground level access to all daily maintenance and service points. This makes for greater safety – as technicians do not have to climb around the machine. It also adds to productivity, as quicker maintenance means less downtime. Its silent and ergonomic cabin is a leader in the market, and boasts excellent visibility for safety and operability, according to the company.

Contributing to its low total cost of ownership are its intelligent hydraulic and compressor systems, which, it says, can deliver 38-42% improved fuel efficiency. Incorporating intelligent technology, the Sandvik DI650i rigs can accommodate scalable automation from on-board options to full automation systems.

Sandvik Namibia has made encouraging progress with recent equipment sales into Namibia, explains van Wyngaard, and he looks forward to a new era of engagement with both the surface and underground mining segments.

“Building on our long-standing relationship with KODO Drilling, we look forward to many more successful ventures with them and other customers,” he says.

Byrnecut progressing to ore production targets at B2Gold’s Wolfshag Underground mine

The on-boarding of Byrnecut Offshore at B2Gold’s Otjikoto Mine has resulted in development rates in the Wolfshag Underground mine recovering, the Canada-based company said in its recently-released June quarter results.

Otjikoto produced 31,417 oz of gold in this quarter of 2022, 2,027 oz below budget, with the lower-than-budgeted gold production due to a slower than planned ramp-up in development of Wolfshag.

The company recently appointed Byrnecut as its new underground mining contractor as part of a $112 million contract. The agreement consists of both development and production, including a total of 10 km of development and a total material movement of 3.2 Mt.

The underground fleet at Wolfshag is mainly from Sandvik Mining & Rock Solutions and currently consists of one DD422i DC jumbo, one DD422i jumbo, two LH517i loaders, three TH551 trucks and a DL432i production drill rig.

B2Gold said development rates in the Wolfshag Underground mine recovered in the recent three-month period, with development ore now expected in the September quarter and stope ore production commencing in the December quarter.

“As a result of this change in ore production timing, the 2022 annual production guidance range for Otjikoto has been revised to between 165,000 and 175,000 oz of gold (original guidance range was between 175,000 and 185,000 oz of gold),” the company said.

As expected, compared with the June quarter of 2021, gold production was 17% higher due to significant waste stripping operations at both the Wolfshag and Otjikoto pits in the first half of 2021.

The initial underground mineral reserve estimate for the down-plunge extension of the Wolfshag deposit includes 210,000 oz of gold in 1.2 Mt of ore at 5.57 g/t Au.

Trevali weighing battery-electric vehicle use in expanded Rosh Pinah plan

Trevali Mining has flagged the potential use of battery-electric vehicles at its Rosh Pinah underground zinc-lead-silver mine, in Namibia, as one route to further reduce the operation’s greenhouse gas emissions if an expansion of throughput goes ahead.

Writing in its just-released 2020 Sustainability Report, the company said the Rosh Pinah expansion, known as RP2.0, could lead to an increase in the underground mining fleet and, with that, the potential use of battery-electric vehicles.

In addition, the company said it was considering increasing the capacity of the underground mobile fleet from 30 t to 60 t trucks for more efficient transportation of material to surface, resulting in better fuel efficiency and reduced ventilation load. The company was also looking to use solar power for at least 30% of the annual energy consumption as a starting point – an aspect the company is close to achieving after signing a a 15-year renewable Power Purchase Agreement with Emerging Markets Energy Services Company (EMESCO) for the supply of solar power to Rosh Pinah in April.

In 2020, Trevali published a positive prefeasibility study on RP2.0, which is projected to increase the throughput of the mine from 700,000 t/y to 1.3 Mt/y, with an 11-year life of mine, post-expansion.

Trevali intended to achieve this through the modification of the processing plant, construction of a paste fill plant, and development of a dedicated portal and ramp to the WF3 deposit.

A feasibility study for the RP2.0 project is underway and is expected to be completed in the second half of this year, with an investment decision thereafter. If approved, construction could commence in the March quarter of 2022, with commercial production potential achieved by the June quarter of 2024, Trevali said.

Trevali taps EMESCO for solar power contract at Rosh Pinah mine

Trevali Mining has entered into a 15-year renewable Power Purchase Agreement with Emerging Markets Energy Services Company (EMESCO) for the supply of solar power to its Rosh Pinah zinc-lead-silver mine in Namibia.

Trevali has committed to achieving an overall greenhouse gas emission reduction target of 25% by 2025 from its 2018 baseline, with the PPA anticipated to deliver 30% of Rosh Pinah’s power requirements during the life of the agreement and reduce GHG emissions at the company level by 6%.

EMESCO will be responsible for the design, permitting, financing and implementation of a solar energy system on a neighbouring property at no cost to Trevali. EMESCO will then sell the power generated to Trevali at a fixed rate that is expected to reduce energy costs by 18% over the 15-year term of the agreement.

EMESCO was chosen based on a variety of factors, including expertise in the field of renewable energy, an understanding of the scope of work required, the ability to execute and deliver on Trevali’s requirements, and pricing, the miner said.

If Trevali makes a positive investment decision on the RP2.0 expansion project, which could see output rise to 3,600 t/d from 2,000 t/d, EMESCO will increase the delivery of power to Rosh Pinah to remain at 30% of the mine’s annual energy consumption as regulated by the Modified Single Buyer framework in Namibia, it added.

Ricus Grimbeek, President & CEO, said: “Our sustainability program commits to significant reductions in GHG emissions, and with the signing of this agreement with EMESCO we have taken a major step towards delivering on our commitment by securing renewable energy while also reducing our expected energy costs.

“The agreement with EMESCO has been designed to scale with the output of the mine so that when we are ready to make the decision to build the RP2.0 Expansion project, the delivery of power will increase to match our requirements.

“We are extremely excited by this partnership at Rosh Pinah and continue to study ways to reduce Trevali’s GHG emissions and deliver on this and our other sustainability targets.”

MacLean Engineering up to the Africa mining challenge

MacLean Engineering’s investment in Africa is paying off, with multiple production support vehicle sales recently secured on the back of an increased presence in South Africa.

Having last month bolstered its largest single fleet in Africa to 11 vehicles at the Kibali gold mine, in the Democratic Republic of Congo, the company is now busy assembling equipment for delivery at an underground mine in Namibia, while making manufacturing and delivery plans for a successful tender for five units that will head to a underground gold mine in Mali.

John-Paul Theunissen, MacLean’s General Manager for Africa, says recent sales could be put down to the company boosting its manufacturing and service capacity on the continent close to two years ago.

“We are now manufacturing for Africa out of South Africa,” he told IM. “Towards the end of 2018/beginning of 2019, we commissioned another 900 sq.m of manufacturing space at our South Africa facility. This means we now have 1,000 sq.m of workshop and assembly space.”

The Free State facility, the first international branch MacLean set up back in the 1990s, also offers maintenance and service support.

These attributes, plus the ability to access MacLean engineers across the globe for equipment troubleshooting, have allowed Africa-based mining companies to get comfortable with the Canada-based brand, according to Theunissen.

“We have really started to build momentum in Africa, increasing the level of service and support closer to home,” he said.

“It is this local aspect that really sells fleets, as opposed to individual machines.”

MacLean now has 1,000 sq.m of workshop and assembly space, Theunissen says

This increased local offering has arrived at just the right time.

While the stricter lockdown measures in South Africa have been lifted – the country has moved from Level 5 to Level 3, allowing mines to return to full capacity (with COVID-safe procedures in place) – companies procuring equipment for Africa are conscious intercontinental deliveries could face upheaval again if a ‘second wave’ of COVID-19 hits.

Some mining companies influenced by recent lockdowns are also making longer-term pledges to adjust their supply chains to take advantage of local expertise, at the same time reducing potential risks that come with buying machines and solutions from overseas suppliers.

This recently enlarged presence in Africa could see MacLean benefit from such moves.

Recent orders

The latest orders Theunissen mentioned could reflect this reality.

In securing a contract to supply three MacLean 3-Series Cassette Trucks (CS3) and four cassettes to the Murray & Roberts Cementation and Lewcor Mining joint venture set to establish the underground stoping horizon at the Wolfshag zone at B2Gold’s Otjikoto mine, in Namibia, the company achieved several ‘firsts’, he said.

“It’s a new customer, Murray & Roberts; a new country, Namibia; and a new miner, B2Gold,” he said.

These units will be assembled in South Africa – another MacLean first – and are due to be delivered to the mine by the end of the last quarter of the year, according to Theunissen.

And, as mentioned before, the company recently bolstered the fleet at the Barrick Gold/AngloGold Ashanti majority owned Kibali gold mine in the DRC.

The latest piece of equipment for the mine – which arrived at the end of July – was one of the company’s personnel carriers.

This adds to the three EC3 Emulsion Chargers, a WS3 Water Sprayer, a FL3 Fuel Lube Truck, and a BT3 Boom Truck – all from MacLean’s trusted Mine-Mate™ Series – that Byrnecut, the original mining contractor at Kibali, brought in from 2013 onwards.

When the Kibali mining model changed to ‘owner-operator’ under the management of Randgold (now Barrick), the fleet got bigger, with the miner adding four new rigs: another EC3, another BT3, an SL3 Scissor Lift with pipe handler attachment, and a TM2 Mobile Concrete Mixer.

MacLean says its expanding presence at Kibali, from the development phase all the way back in 2013 up to achieving record production numbers in 2019 and 2020, illustrates the “MacLean Advantage in action”.

It explained: “MacLean’s dedicated team in South Africa has worked closely with mine management and operators to provide the training, maintenance and support needed to keep Kibali running smoothly. With operations forecast to continue at Kibali through 2036, MacLean looks forward to providing dependable support for years to come.”

Tech take-up

Mines like Kibali – one of the most technologically advanced in Africa – are gradually becoming more and more automated in an effort to increase productivity and safety.

Already one of the world’s most highly automated underground gold mines, Kibali’s backbone is Sandvik’s AutoMine Multi Fleet system, supervised on surface by a single operator. This system, in a world first, allows a fleet of up to five LHDs to be operated autonomously, 750 m below the surface, within the same 6 m x 6 m production drive while using designated passing bays to maintain traffic flow, Barrick says. A similar system is used in the production levels to feed the ore passes, according to the company.

While MacLean’s production support vehicles often interact with these autonomous loaders, for the time being they are still manned by operators.

This is set to change into the future, according to Theunissen.

“The Advanced Vehicle Technology Team (AVT) in Canada is moving into the automation space,” he said. “We’re looking to integrate our own digitalised systems into those of OEMs such as Sandvik and Epiroc to ensure fully interoperable autonomous operation.”

Within the AVT, the Advanced Vehicle Technology group embedded at the MacLean Research and Demonstration Facility, in Sudbury, Ontario (pictured below), has over 20 engineering staff working on remotely controlled to fully autonomous vehicle operation, using radar, LiDAR, and vehicle monitoring technology, according to MacLean.

This team has already come up with vehicle telemetry hardware and software, and virtual reality training tools. It is also transitioning to a cloud-based platform for documentation, parts ordering, and training content called Documoto.

While these technology developments will, in the future, underwrite the company’s transition to offering machines capable of fully autonomous operation, MacLean is already at the front of the pack when it comes to facilitating the industry’s electrification movement.

In Canada, it has more than 30 battery electric mining vehicles (BEVs) working underground – at 10 mine sites, across four provinces, with more than 50,000 operating hours amassed.

While Africa as a whole might not yet have the energy infrastructure in place to fully leverage these ‘green’ BEVs – many mines remain off grid and reliant on diesel power – Theunissen has seen grid-connected miners in South Africa show interest in taking on these machines.

“In South Africa there is already appetite for BEVs,” he said. “We see it coming through in the RFIs (request for information) we get on projects.”

MacLean has an advantage over some of its competitors when it comes to converting these RFIs into sales.

Not only has it got thousands of operating hours under its belt, it also has engineers in place that can calculate the total cost of ownership savings a specific mine will achieve should they bring BEVs into their fleets. Due to the increase in upfront cost currently seen when comparing diesel- with battery-powered vehicles, this type of analysis is crucial to securing orders.

“We can show them how the machine will fit into the mining cycle and provide in-house calculations on ventilation and mine design savings,” Theunissen said. “This helps assist end users when it comes to long-term decision making for the mine.”

For countries in Africa to get on board the electrification train like those mines in Canada have, Theunissen thinks governments will need to introduce incentives for mines to change their energy inputs and adopt BEVs.

Should this happen, MacLean will be equipped both within the continent and internationally to take on that challenge.

BME keeps supply up amid lockdown as it prepares for COVID-19-related business changes

COVID-19 lockdown restrictions around Southern Africa have thrown the spotlight on mines’ supply security, with key inputs like explosives and blasting services among these.

According to Albie Visser, General Manager at blasting specialist BME, mines have relied heavily on the flexibility and ingenuity of service providers to keep the supply chain functioning.

“The first weeks of the lockdown were challenging, especially regarding the logistics of moving our emulsion product across national borders from South Africa into other southern African countries,” Visser said. “Different countries – and even different border posts – applied different rules, making it difficult to know what the exact compliance requirements were.”

Albie Visser, General Manager at BME

He noted the pandemic had caught most authorities unaware, leading to regulations being hurriedly developed and enforced.

“In some cases, the regulatory requirements were not practical,” he said. “At one border, for instance, drivers were required to have a COVID-19 test not older than three days – but in South Africa it took nine days to get results from a test through normal channels.”

This meant that innovative thinking was called for, and BME worked closely with its own suppliers and the mines themselves. While some deliveries were initially delayed by border issues, the company’s responsiveness and agility kept up its deliveries to site, it said.

National lockdowns in the region affected the mining sectors differently from country to country.

“South Africa’s lockdown saw demand for emulsion drop sharply at first, but this has almost returned to normal as mines ramped up to full production where possible,” he said. “While mining in Botswana has slowed, Namibia’s mining industry has been more resilient and our supplies to Zambia are almost unaffected.”

Site precautions

In South Africa, BME is working on many mine sites, with an average of three teams per site. By conducting risk assessments and adapting its existing safety systems, BME quickly developed its own COVID-19 protocols in line with national safety regulations – even before some of the mines finalised their own systems.

Among the measures BME has applied is to divide staff into small groups to keep closer control of movements and restrict infections. For example, each group will stay together for transport purposes, and will use only one specified bus.

“Each bus, which has a thermometer for daily testing, will collect staff from their homes,” Visser said. “We know exactly who they live with, for purposes of future contact tracing.”

It does mean more buses arriving at the work site, but any infection picked up can then be controlled and traced within that group. There is also another screening test at the mine site when staff arrive, and the necessary social distancing is observed.

“To date our measures have been very effective, with no COVID-19 infections at any of our operations,” he said.

Overcoming barriers

Outside of South Africa, there have been some notable achievements in the face of COVID-19 related lockdowns.

Joe Keenan, Managing Director of BME, relayed a few of these.

Joe Keenan, Managing Director of BME

“Among the logistical achievements, for instance, was the timeous shipping of resources to customers in Australia and West Africa – which was done in anticipation of the lockdown,” he said.

BME was also able to continue satisfying the requirements of one of Zambia’s largest copper producers, despite the difficulties of negotiating border regulations.

At the same time as this, the company is continuing to roll out large projects for major customers, while keeping most of its staff working remotely. This includes the recruitment of about 170 people for one key project, and the continuation of on-site testing.

Automation, remote optionality

From the manufacturing perspective, BME’s facilities are also well positioned to keep feeding the supply chain even under lockdown conditions, according to Ralf Hennecke, BME’s General Manager: Technology and Marketing.

“Most of our production plant processes are highly automated, so we can readily apply the necessary social distancing and minimise staff without affecting production,” Hennecke said. “This applies to our explosives facilities as well as our factories for non-electric and electronic detonators.”

Ralf Hennecke BME General Manager: Technology and Marketing

BME has put in considerable investment in the automation of its manufacturing plant at Delmas in Mpumalanga, South Africa, for instance. While the driver for this process was primarily the quality of its emulsion product, the effect has been to enhance security of supply while applying strict social distancing protocols, it said.

Keenan said: “At our facility in Losberg, Gauteng, where we manufacture our AXXIS™ equipment and non-electric detonation systems, there is also a high level of automation. We can therefore accommodate the COVID-19 regulations without affecting the value chain.”

Even the company’s remote bulk emulsion plants – often located on customer’s mine sites – can be operated with minimal staff.

Hennecke highlighted that BME’s technology, including planning and reporting platforms like BLASTMAP™ and XPLOLOG™, also assist mines to reduce opportunities for COVID-19 transmission.

“Our technological innovations allow data to be digitally captured, stored and transferred to the mine’s operational and administrative systems,” he said. “This can be done safely with only a few human touchpoints, and also in real time for greater efficiency.”

The future

While the current efforts are to keep mining operations running normally, the future will see considerable changes in how suppliers like BME support customers, according to Keenan.

“The leveraging of technological innovation to keep mine sites safe and efficient becomes an even more vital imperative for technology providers,” he said.

Operationally, there will be ongoing focus on social distancing and digital processes to reduce proximity between employees.

With strict requirements limiting face to face interaction, more communication with customers will also have to be conducted digitally.

These communication systems will also have to be adapted to streamline the sales process and keep contracts flowing, according to BME.

“Creative solutions will need to be found for how to manage tenders, for example, especially where site visits are required,” Kennan said. “There are still various practical issues to be resolved so that normal procurement can continue.”

In terms of further expediting the shift to non-contact interaction with customers, BME’s new enterprise resource planning system enhances its shared services capacity, allowing less paperwork and more electronic documentation and processing.

ABB to energise world’s largest advanced diamond recovery vessel

ABB has won a contract from Damen Shipyards Group to deliver an advanced power system for Debmarine Namibia’s custom-built diamond recovery vessel.

The Switzerland-based company will supply an integrated power system package that will ensure the world’s largest and most technologically advanced diamond recovery vessel meets exceptional safety, efficiency and availability requirements, it said. The vessel is being built by Damen at Damen Shipyards Mangalia on the Black Sea, in Romania.

With a total cost of $468 million, the vessel is the largest single investment ever made in the marine diamond industry, according to Debmarine. It deploys advanced subsea crawling – a technique for recovering diamonds from the seabed. The new build will be delivered to Debmarine Namibia, a joint venture between the Government of the Republic of Namibia and De Beers Group, in 2022.

Debmarine Namibia extracts some of the highest quality diamonds available anywhere from water of between 90-150 m deep off the south west coast of the country.

The new 177 m ship has been designed by Norway-based naval architects, Marin Teknikk. It will become the largest ship in the owner’s fleet, exceeding the size of Debmarine Namibia’s current largest vessel, the Mafuta, by 8,000 t displacement (vessel weight based on the amount of water displaced by the hull). It is expected to increase the shipowner’s annual production by 35%, contributing an additional 500,000 ct to today’s production levels.

The offshore mining specialist previously installed ABB’s power systems on board the SS Nujoma (SSN), Debmarine Namibia’s deep-water diamond exploration and sampling vessel.

Michael Curtis, who is heading the new build project for Debmarine Namibia, said: “The success of the SSN, with high reliability, efficient positioning and low fuel consumption coupled with safe operation, was instrumental in selecting the same systems for the new diamond recovery vessel, with ABB’s power systems being an integral part of the solution.”

The latest ABB technology will ensure the vessel achieves unsurpassed uptime, according to the company.

In addition to the advanced system for power generation, distribution and variable speed drive propulsion systems, the solution includes a large online double-conversion marine uninterruptible power supply (MUPS) to support the ship’s control processes, significantly reducing the risk of critical power loss and downtime.

“ABB’s MUPS is designed for undisrupted availability, ensuring power backup for the vessel’s on-board control systems of the subsea-crawler and processing plant that sorts through sediment lifted from the seabed to extract diamonds,” ABB said. “ABB’s advanced and tightly integrated power system will help optimise engine loading, as well as reduce running hours and fuel costs, and decrease maintenance needs.”

Juha Koskela, Managing Director, ABB Marine & Ports, said: “This is a truly special ship, packed with sophisticated technology, and a project demanding an especially close relationship with the customer to ensure that optimal solutions were delivered for exact specifications.

“We are thrilled to see that the team behind this advanced vessel recognises the benefits of efficiency, safety and uptime available through integration. This success is also consistent with growing traction for ABB’s electric, digital and connected solutions across an increasing number of vessel types and operational profiles.”

SKF and NLS collaborating in Namibia mining market

SKF has appointed a new authorised distributor in Namibia as it looks to grow its network to deliver “innovative bearing and rotation technology solutions to customers across the sub-continent”, Christian Murman, SKF South Africa’s Business Development Manager – Neighbouring Countries, says.

Namibian Lubrication Systems (NLS), which specialises in the supply of lubrication equipment and systems to the industrial and mining sectors across the entire Erongo, Khomas, Karas and Otjozondjupa regions of Namibia, has been an SKF authorised distributor since September 2019.

The company was established by André Bezuidenhout in Oranjemund in 2000 and, in the same year, it was appointed as the sole distributor for Lincoln Lubrication South Africa, part of the SKF global group. NLS also holds the title as the only company in Namibia qualified to service and repair all Lincoln Lubrication equipment.

Murman explains how SKF and NLS have been collaborating since being the Namibia-based company came on board as an authorised distributor: “While calling on customers together with our new authorised distributor, we received an enquiry from a gold mine for a replacement bearing for their stock for an upcoming project in Q1 (March quarter) 2020.”

The gold mine shared a long history with NLS and Lincoln products giving the company an in-depth knowledge of the operation, SKF said.

“But, as a newly appointed SKF authorised dealer, NLS was still on a learning curve regarding SKF products and thus decided to call upon the expertise of SKF’s Engineering Department. Cody Petersen, Junior Project Engineer at SKF, was considered as the best person to assist in making this project a bonafide success.”

After putting heads together, the SKF 4176 ECAK30/C3W33 replacement bearing was recommended. NLS submitted a quote and, after a follow-up call, the mine placed the order in November.

This successful project and collaboration between the companies affirms SKF’s decision to appoint NLS as an authorised distributor, SKF said.

“The company has an excellent footprint within the country, boasts a stellar reputation for on-site service and has technicians on contract at most of the mines in Namibia who look after Lincoln products,” Murman said.

Now, as a SKF authorised distributor, NLS is responsible for delivering the comprehensive SKF product and service portfolio in Namibia focusing on a condition monitoring service delivered by the company’s technicians who have been specifically trained in this field.

“NLS’ ultimate goal is to have multi-skilled technicians that are able to offer customers a complete maintenance package, thereby securing all the Lincoln Lubrication and SKF product offerings,” SKF said.

Murman concluded: “The success of this project solidifies our position as a powerhouse duo in the Namibian mining space. Furthermore, this agreement enables us to leverage off our Lincoln Distributor’s excellent reputation in the local market.

“When customers can see the real value that our authorised dealers add to their mine, plant or operation and realise that they are able to rely on their expertise, it becomes a win-win scenario.”
