Redpath continues mechanised sinking evolution with S20+ deployment at Odyssey

Redpath is continuing its focus on mechanised shaft sinking operations, with the latest example being the planned use of the hydraulic shaft mucker S20+ at the Canadian Malartic Partnership’s (CMP) Odyssey gold project in Quebec, Canada.

Redpath Canada was recently contracted by the CMP to sink a 6.5-m diameter, 1,800-m deep concrete lined shaft at Odyssey, a project that has the potential to become one of Canada’s largest and most technologically advanced underground gold mines.

CMP, which is 50:50 owned by Yamana Gold Inc and Agnico Eagle Ltd, previously laid out plans to extract 19,000 t of ore at an estimated grade of about 2.75 g/t gold and roughly 5,000 t/d of waste rock during peak operations at Odyssey. The ore will be processed at the operation’s existing plant, which will eventually be adapted to the future mine’s needs including shifting from 57,000 t/d to 20,000 t/d. The ore will be hauled to surface using Blair production hoists with use of both shaft bottom and mid-shaft ore handling systems.

The sinking concept at Odyssey includes the use of the S20+, which was built by Redpath Deilmann in Germany. A previous iteration of this machine, the S20, was used with success on four shaft projects in both soft rock – with an integrated tool package – and hard rock.

The S20+ offers similar capacity/productivity to a North American pneumatic telescopic boom mucker but with a much easier learning curve for operators, according to Kevin Melong, Vice President – Shafts and Technical Services, at Redpath Canada.

Unlike the RD S100, which can move independently of the galloway within the shaft via a telescopic boom, the S20+ is connected to the galloway, requiring the lowering of the galloway to move the mucker into position for mucking.

Melong added: “The S20+ does present some potential for concurrent mucking when in and around the shaft station construction/excavation, but, in general, does not act independent of the stage as in the S100 design.”

Fitted with a bucket as standard, the S20+ offers a maximum digging depth of 7.96 m and a bucket volume of 560 litres. It also offers good flexibility, with the bucket capable of six rotations per minute.

Alongside the S20+ and the aforementioned S100, Redpath has been mechanising the shaft sinking process in mining through the use of large-diameter raiseboring equipment and operation of Herrenknecht’s Shaft Boring Roadheader (in soft-to-medium rock). The company is also working with Herrenknecht on the development of the Shaft Boring Cutterhead, a machine developed for medium-to-hard rock applications up to 250 MPa UCS.

Rio Tinto funds initial underground development at Kennecott copper ops

Rio Tinto has approved a $55 million investment in development capital to start underground mining and expand production at its Kennecott copper operations in Utah, USA.

Underground mining will initially focus on an area known as the Lower Commercial Skarn (LCS), which will deliver a total of around 30,000 t of additional high-quality mined copper through the period to 2027 alongside open-pit operations, Rio says. The first ore is expected to be produced in early 2023, with full production in the second half of the year. It will be processed through the existing facilities at Kennecott, one of only two operating copper smelters in the US.

Kennecott holds the potential for significant and attractive underground development. The LCS is the first step towards this, with a mineral resource of 7.5 Mt at 1.9% Cu, 0.84 g/t Au, 11.26 g/t Ag and 0.015% Mo identified based on drilling and a probable reserve of 1.7 Mt at 1.9% Cu, 0.71 g/t Au, 10.07 g/t Ag and 0.044% Mo.

Underground battery-electric vehicles are currently being trialled at Kennecott to improve employee health and safety, increase productivity and reduce carbon emissions from future underground mining fleets. A battery-electric haul truck and loader supplied by Sandvik Mining and Rock Solutions – a Sandvik LH518B 18 t battery-electric LHD and a Sandvik Z50 50 t battery-electric haul truck – are being used to evaluate performance and suitability as part of underground development work.

Rio Tinto Copper Chief Executive, Bold Baatar, said: “This investment will allow us to quickly bring additional volumes of high-quality copper to the market and build our knowledge and capabilities as we evaluate larger scale underground mining at Kennecott. We are progressing a range of options for a significant resource that is yet to be developed at Kennecott, which could extend our supply of copper and other critical materials needed for electric vehicles and renewable power technologies.

“Trialling underground battery-electric vehicles is an exciting step in our work to create a safer workplace for our employees, increase the productivity of the mine and reduce emissions from our operations. We look forward to seeing their potential for deployment.”

Existing undergound infrastructure is currently being extended to enable early access to the next underground resource and undertake characterisation studies. A feasibility study to inform decisions on the next phase of underground production is expected to be completed in 2023. This will be one of several potential stages currently being investigated.

Feasibility studies are also being progressed to extend open-pit mining at Kennecott beyond 2032.

RUC Cementation Mining to carry out raiseboring at Bellevue gold project

RUC Cementation Mining has been awarded a raisebore contract at the Bellevue gold project, 40 km northwest of Leinster in Western Australia.

The project, which is valued at A$15.8 million ($10.6 million) over 28 months, provides for RUC’s Raiseboring division to establish vent rises, return air rises and underground escapeways at the underground mine.

RUC, a subsidiary of the Murray and Roberts Group, also completed several raisebores at the Bellevue gold project during the previous operations, project owner Bellevue Gold said in a separate announcement earlier this week.

RUC calls itself the industry leader for raiseboring, having proprietary techniques and equipment, cost saving initiatives and a localised offsite support centre based in Kalgoorlie, Western Australia. It says it is also focused on delivering services with good environmental, social and governance practices, which align with Bellevue’s strong commitments to be Australia’s first carbon-neutral gold producer.

Bellevue is forecasting production of 200,000 oz/y during years one to five at an all-in sustaining cost of A$922/oz ($618/oz) at its operation.

Sedgman formally awarded EPC contract for Artemis’ Blackwater gold project

CIMIC Group’s mineral processing company, Sedgman, has been awarded an engineering, procurement and construction (EPC) contract to deliver services for Artemis Gold at the Blackwater gold project in British Columbia, Canada.

The EPC contract, which supersedes the temporary interim service agreement announced on May 2, 2022, will generate revenue for Sedgman of C$318 million ($245 million).

Sedgman will design and construct the processing and non-processing infrastructure for a 6 Mt/y carbon-in-leach gold plant at the project.

Even before this announcement, Sedgman had made good headway on the project, executing an agreement with Metso Outotec to secure supply and delivery of crushing and grinding equipment for the processing plant.

The project schedule as laid out by Artemis supporting the EPC contract with Sedgman includes the following assumptions:

  • Receipt of the BC Mines Act and related permits in the Fall of 2022;
  • Construction mobilisation and major works preparations commence in the March quarter of 2023 with process plant bulk earthworks scheduled to be completed prior to the start of major works;
  • Commissioning activities of the process facility to commence in the firts half of 2024; and
  • First gold pour expected in the September quarter of 2024.

CIMIC Group Executive Chairman, Juan Santamaria, said: “Sedgman and Artemis have already commenced initial design and procurement work at the project, helping Artemis to unlock the value of this key gold project and work towards its first gold pour in 2024.”

Sedgman Managing Director, Grant Fraser, said: “We are pleased to be working with Artemis Gold on this exciting project and look forward to continuing our strong working relationship to ensure successful outcomes for both Sedgman and Artemis.”

Work is expected to be completed in the September quarter of 2024.

Artemis has said previously that Stage 1 development at Blackwater should lead to the building of a 6-9 Mt/y operation (6 Mt/y in years 1-4 and 9 Mt/y in year 5) able to produce around 312,000 oz/y of gold.

STRACON and RIPCONCIV look to collaborate on Curipamba-El Domo copper-gold mine build

Adventus Mining Corporation and Salazar Resources Limited have signed a Letter of Intent (LOI) for the award of a mining and construction contract to a joint venture between STRACON S.A., an established Peruvian mining contractor with operations throughout Latin America, and RIPCONCIV, a large and respected Ecuadorian infrastructure construction contractor, related to development of the Curipamba-El Domo copper-gold project in central Ecuador.

The LOI allows the parties to immediately commence activities relating to local community-targeted training and employment, constructability reviews, logistics studies and execution planning – all of which are value-add activities directly supporting Adventus and Salazar’s plan to formally commence construction of the project in the June quarter of 2023.

A definitive agreement is expected to be executed in the December quarter of 2022, which will be structured in an alliance-partnership model to ensure focus on the best solutions for the project while ensuring that risks are allocated to the parties best equipped to manage and mitigate. The STRACON-RIPCONCIV JV will be responsible for the successful construction of the open pit, tailings facilities, and associated mine infrastructure as well as the first two years of mine operation.

In 2021, Adventus and Salazar released an open-pit mine feasibility study and updated preliminary economic assessment on a separate underground mine option for the project. This outlined a 10-year open-pit operation producing, on average, 21,390 t/y of copper-equivalent over the 10-year life-of-mine, alongside 20,000 t/y of copper-equivalent payable output from years 11-14 from the underground.

On site, focus has been on drilling to support the detailed engineering program and the implementation of health, safety, security and environmental management plans in anticipation of formal construction commencement in the June quarter of 2023.

Work continues to advance on site with an ongoing pre-construction program involving activities such as geotechnical and hydrogeological drilling, camp installation, IT, infrastructure, logistics planning, community hiring, public and private security provisions, water management and electrical power systems.

A contract for the detailed engineering and design of the tailings storage facility (TSF), waste rock facilities (WRF) and associated infrastructure was recently awarded to engineering firm Klohn Crippen Berger (KCB). Design work has commenced and is expected to be completed in the March quarter of 2023, prior to the start of construction.

In June 2022, KCB completed a study to optimise the use of waste rock during the pre-strip period for use as construction material. This work resulted in an anticipated overall reduction of pre-strip volume of approximately 3 Mt of waste, which is expected to reduce construction costs and provide more schedule flexibility during the pre-production period of project development. An updated mine plan based on the reduced pre-strip quantities is expected to be completedthis month, which will then be used by the STRACON-RIPCONCIV JV to finalise fleet selection and manpower planning.

Engineering for the project process plant and surface infrastructure is now well underway by engineering firm DRA Global, the lead detailed engineering consultant for the project. Work is on schedule and currently focused on the negotiation and award of long lead equipment packages from mining equipment vendors, with a 30% progress milestone review planned for late September 2022.

Following the successful receipt of ESIA technical approval from the Government of Ecuador in May 2022, Adventus and Salazar are continuing to plan for the public consultation process. The Government of Ecuador is in the process of redefining the requirements for this consultation process and the President of Ecuador is expected to enact a corresponding decree in 2022.

The final control capital budget for the project is expected to be announced in the June quarter of 2023. To date, the companies have seen some reductions in projected capital costs such as from improvements in the TSF design, which are tending to offset cost pressures associated with inflation and global geopolitical instability.

At a project level, the Curipamba-El Domo copper-gold asset is owned 75% by Adventus and 25% by Salazar.

Green Gold to test cyanide reduction tech on Poseidon’s Windarra gold tailings project

Poseidon Nickel says it has signed a binding heads of agreement with Green Gold Projects Pte Ltd (GGP) for the processing of the Windarra Gold Tailings Project in Western Australia.

The agreement could see Green Gold deploy its patented technology at the project, which includes ReCYN, which, through the use of a resin-bead absorbent, can reduce cyanide consumption by 50%, capturing free cyanide from the plant tailings and recycling it back into the leach circuit while recovering metal complexes and making them available for sale.

In the process, ReCYN detoxifies the tailings stream and guarantees 100%-compliant clean water discharge, according to Green Gold.

Its technology is already being tested at PT Agincourt Resources’ Martabe gold-silver operation in Sumatra, Indonesia, to detoxify tailings and recover cyanide and copper.

The binding agreement outlines the proposed partnership with GGP for the processing of the tailings, with a final agreement subject to GGP being satisfied with the outcome of metallurgical test work and a bankable feasibility study being completed at GGP’s expense.

The Windarra Gold Tailings Project consists of the Windarra and Lancefield (pictured) tailings with combined mineral resources of 5.96 Mt at 0.84 g/t Au and 2.1 g/t Ag, containing 180,000 oz of gold. A definitive feasibility study (DFS) was completed by Poseidon and released in mid-2021, which investigated using two different mining methods on the Windarra tailings, amphibious dredging or hydraulic mining and the construction of a modular 1.5 Mt/y processing plant to recover up to 55,000 oz of gold over a 45-month period.

The economic analysis indicated a project with an net present of circa A$20 million ($13.5 million) and internal rate of return of 45-50% depending on the mining method, assuming a gold price of $1,750/oz and an exchange rate of A$1 to US$0.75.

“While the outcome of the DFS was positive, the company is focused on the restart of the Black Swan project and decided that finding a partner to develop and operate the Windarra Gold Tailings Project was the best outcome for shareholders,” Poseidon said. “This process commenced earlier in the year and significant interest was received from various parties.”

Poseidon Nickel Managing Director and CEO, Peter Harold, said: “This agreement (with GGP) is a significant milestone in the company’s strategy to monetise the Windarra Gold Tailings Project. Green Gold Projects is an experienced developer and operator and is currently active in 30 projects globally.”

Upon achieving the test work and feasibility study milestones, GGP will earn a farm-in interest in the project. In return, Poseidon will receive consideration in the form of cash payments – upfront and upon project financing and a free carried profit interest of 8%. The funding, development and operation of the project will be the responsibility of Green Gold.

“The proposed partnership with Green Gold is an ideal outcome for Poseidon given our focus on the development of our nickel projects,” Harold said.

GGP was selected as the preferred partner given its experience as a developer and operator of similar projects, Poseidon said. Its patented technology has the potential to improve the economics of the project, according to the company.

The binding agreement outlines certain conditions to be met to reach a final agreement to develop the project. These include:

  • Metallurgical test work performed by GGP on the Windarra and Lancefield tailings to determine if its patented technology can improve gold recovery;
  • The rights and obligations of the Lancefield tailings right-to-treat Agreement are assigned to GGP; and
  • GGP receiving Foreign Investment Review Board and any other anticipated approval if required.

Subject to the satisfaction of these pre-conditions, Poseidon will grant GGP the right to farm-in to the project subject to the completion of the following milestones:

  • Milestone 1: GGP making a non-refundable upfront payment of A$250,000 upon satisfying the pre-conditions mentioned above to earn an initial 13.8% interest in the project;
  • Milestone 2: GGP completing a positive bankable feasibility study on the project to earn a further 13.8% interest in the project; and
  • Milestone 3: GGP making a final investment decision, securing funding for the project, and making a non-refundable payment of A$1 million to Poseidon to earn a further 64.4% interest in the project.

Poseidon will then retain an 8% free carried profit interest in the project, which entitles the company to 8% of the profit while not contributing to any capital or any other payments. The binding agreement also specifies that the project must be in production within three years from the date that the last farm-in milestone is satisfied, and that GGP will be solely responsible for meeting any rehabilitation or other environmental liabilities arising from the project.

Westgold signs up MLG for transport, maintenance and management services

MLG Oz Limited says it has been awarded a material five-year contract by Westgold Resources Limited that will see the METS company service the gold miner’s operational hubs across the Murchison and Bryah Basin regions.

The contract, which leverages MLG’s integrated support model, is focused on enhancing Westgold’s operating efficiencies. It also consolidates MLG’s resources in the Mid-West region and represents a material win for the company, it said.

Westgold owns and operates the Tuckabianna, Bluebird and Fortnum processing hubs across the Murchison and Bryah Basin regions of Western Australia, with its objective to leverage MLG’s existing fleet capacity to enhance operational efficiencies and use MLG’s latest road haulage technical advancements, MLG said.

Westgold is to provide dedicated maintenance facilities at each of its sites to support MLG operations.

The scope of services includes the delivery of in-pit, off- and on-road haulage, road maintenance and run of mine management services activities across all of Westgold’s operations.

The initial ramp up and mobilisation activities are expected to commence in October 2022, with anticipated annual revenues of circa-A$40 million ($27 million) with revenue to build from December 2022.

MLG founder, Managing Director and majority shareholder, Murray Leahy, said: “We are delighted Westgold has selected us to enhance their operations in the Murchison and Bryah Basin regions. Westgold is focused on driving cost and operational efficiencies to enhance the profitability of its business and we are proud to have been chosen as a key and trusted business partner.

“This is a large opportunity for MLG to establish a long-term relationship with a growth-oriented gold miner and Westgold’s faith in MLG represents a significant endorsement of our capabilities.”

MLG Oz is a founder-led business that provides a range of services to mine sites, integrated around the needs of client’s ore processing facilities.

Metso Outotec aims for higher capacities as ore sorting offering develops

The entry of Metso Outotec into the bulk ore sorting space arguably heralds the beginning of a new stage of market adoption – one that is focused on significant throughputs across multiple commodities.

In May, the mining OEM announced a collaboration agreement with Malvern Panalytical, a company that has been using Pulsed Fast Thermal Neutron Activation (PFTNA) technology onboard its cross-belt analysers to analyse and help divert ore and waste streams with improved accuracy.

Up until that announcement, Metso Outotec had mooted the benefits of bulk ore sorting in several industry articles. On the smaller scale, it had also renewed its ongoing agreement with particle ore sorting major player, TOMRA.

The company said its agreement with Malvern Panalytical, which has previously worked on bulk sorting projects with Anglo American among others, brought together its expertise in crushing and bulk material handling solutions with Malvern Panalytical’s ore analysis nous to offer an industry-leading portfolio of solutions for bulk ore sorting.

Rashmi Kasat, Vice President, Digital technologies at Metso Outotec, said in the press release that the pact with Malvern Panalytical would allow the company to meet the industry’s increasing sustainability and resource efficiency needs in an enhanced way in the early comminution stage.

“Sensor-based bulk ore sorting and data-driven analysis upgrades low grade or waste stockpiles, making them economical and far less energy-intensive to treat,” she said.

There are obvious positive benefits up- and down-stream of sensor-based sorting too, with the ability to carry out a low-cost mining method (upstream), as well as reduced capital investments in downstream equipment already shown with early-adopter projects.

That is before considering the relative energy and water reduction requirements that come with applying the technology.

Kasat later told IM that the company’s existing portfolio of material handling modules, crushing stations or mobile crushing equipment, as well as bulk material handling solutions, already “complement” the concept of bulk sorting.

“The addition of the bulk sensor is easily achieved,” she clarified. “The diversion mechanism will be included as well to be able to offer the whole plant out of one hand.”

With crushing stations – at least in the in-pit crushing and conveying (IPCC) space – that can go up to 15,000 t/h (see the company’s Foresight™ semi-mobile primary gyratory station), the prospect of Metso Outotec making a concerted effort to get into the bulk ore sorting space bodes well for the rising throughputs of projects.

NextOre recently claimed it had commissioned the world’s largest bulk ore sorting system at First Quantum Minerals’ Kansanshi copper mine in Zambia. This installation, which uses the company’s magnetic resonance technology, comes in at a 2,800 t/h-rated capacity.

Scantech, meanwhile, recently confirmed it has a GEOSCAN GOLD installation using prompt gamma neutron activation analysis technology for bulk sensing/sorting up and running that uses a diversion system at conveyed flow rates of more than 6,000 t/h.

Kasat, without naming a range, confirmed Metso Outotec was targeting “higher capacities” in line with the sensors available on the market. She also clarified that the agreement with Malvern Panalytical was “non-exclusive”.

“We will choose all our sensor/analyser partners strategically,” she explained. “Malvern Panalytical has a leading position and history in this field with proven technology for ore sensing. We will leverage our and their Tier 1 position in the industry for our bulk ore sorting offering.”

Malvern Panalytical uses Pulsed Fast Thermal Neutron Activation technology onboard its cross-belt analysers to analyse and help divert ore and waste streams with improved accuracy

As the type of sensor to be employed varies based on several factors including mineralogy, plant capacity, application of bulk ore sorting, etc, Metso Outotec will identify the right partners for the right need, she explained.

The major constraints for these sensors are often measurement times and sensor penetration, according to Kasat.

“There are very few sensors out there that can do sensing of a 500-mm-deep bed of rock on a conveyor belt, moving at 5-6 m/s,” she said. “But our current and future prospective partners are working on developing the technologies to reduce measurement times without compromising the accuracy of measurement.”

The mining OEM is looking to, in most cases, provide ‘plug and play’ flowsheets for bulk ore sorting and then carry out the required customisation per sensor.

This plan reinforces Kasat’s assertion that there is no ‘one-size-fits-all’ concept in bulk ore sorting applications.

For new projects, the process could see the company start with metallurgical testing, progress to mobile/fixed pilot plants in the “backyard” to test the accuracy of the sensors for the given application, and then find the right solution for the customer’s use case.

Renato Verdejo, Business Development Lead for Bulk Ore Sorting at Metso Outotec, added: “For existing plants, we will install the sensor over the belt conveyor and analyse the results after selecting the right sensor for this sorting application.”

Metso Outotec intends to focus on major commodities like copper, iron, nickel and gold, among others, with applications such as waste/ore sorting, low grade re-crushing and beneficiation process optimisation.

Within this wide remit – and in line with its non-exclusive agreements with Malvern Panalytical and TOMRA – the company is also considering the combination of both bulk and particle sorting in flowsheet designs.

Metso Outotec, in 2021, renewed its ongoing agreement with particle ore sorting major player, TOMRA

“The combination of the superior throughput of a bulk application with the selectivity of particle sorting in a rougher-scavenger setup is something that can bring sorting to high volume mines in the future,” Kasat said.

“Plant concepts and flowsheets have already been conceptualised and we expect the first deliveries to be in pilot stations to test the sensors on site,” she added, saying that the tonnage requirements for bulk ore sorting sensor validation meant a bulk sensor would have to be piloted in the field to get statistically meaningful data about the properties of the deposit.

Metso Outotec’s crushing system offering will form the “base” for these solutions, with ore sorting optionality available to all customers, she said.

This sensor-based optionality also overlaps with another in-demand part of Metso Outotec’s business: IPCC.

The company’s dedicated team in Germany are responsible for this area, developing projects backed by comprehensive studies.

They – like most of the industry – are aware of the potential application for sensor-based ore sorting in IPCC projects.

Markus Dammers, Senior Engineer of Mine Planning for Metso Outotec and one of the team members in Germany, said there were applications for both bulk and particle sorting in IPCC applications, with the former likely integrated after primary crushing and the latter after secondary/tertiary crushing.

“Bulk ore sorting in an IPCC application should be integrated after primary crushing in order to recover marginal material determined as waste in the block model, or reject waste from the ore stream,” he said.

Bulk ore sorting in an IPCC application should be integrated after primary crushing in order to recover marginal material determined as waste in the block model, or reject waste from the ore stream, according to Markus Dammers

If integrated after secondary or tertiary crushing, it becomes less effective, with the ore’s heterogeneity decreasing every time the ore is rehandled, transferred, crushed, blended, etc.

“In this manner one can take advantage of the natural variability in the deposit, rather than blending it out, with bulk ore sorting,” he said.

After secondary and tertiary crushing, particle sorting may be applied as a “standalone or subsequent ‘cleaner’ process step”, he added.

With Metso Outotec open to the inclusion of ore sorting in fully-mobile, semi-mobile and stationary crushing stations within an IPCC context, the company has many potential customers – existing and new – out there.

And that is just in IPCC applications.

The company also has hundreds of crushing stations on fixed plant installations that could represent potential sorting opportunities.

Metso Outotec, on top of this massive install base, has a few advantages over traditional ore sorting vendors in that it understands the plant that goes around the analysis and diversion process associated with ore sorting; knows how important uptime is to its customers; and, through sophisticated modelling, realises what impact changes in the flowsheet will have up- and down-stream of such equipment.

“The key point here is to have all the equipment to handle and process the ore to feed the sorter and, later, having the technology to divert the material and retain the availability of the plant without changes,” Kasat said.

Energised by its Planet Positive aims of responding to the sustainability requirements of its customers in the fields of energy or water efficiency, emissions, circularity and safety, the company is now ready to flex its processing plant muscles to increase the industry’s adoption of bulk and particle sorting technology.

RCT to automate Komatsu WX07s for WestAuz Mining at Norseman project

RCT says it has been selected as the preferred automation partner of Kalgoorlie-based contract mining company WestAuz Mining.

Westauz Mining is an underground mining specialist planning to equip two of its Komatsu WX07 7-t-payload LHDs with RCT’s Digital Automation solution.

These loaders will be deployed at the Norseman Project, a gold mine site located in the Goldfields – Esperance region of Western Australia.

Norseman is 50%-owned by ASX-listed Pantoro Ltd (Tulla Resources owns the remaining 50%), which said earlier this month at the Diggers and Dealers conference, in Kalgoorlie, that mining – both open-pit and underground – had commenced ahead of first gold this quarter.

Pantoro has focused initial project planning on six initial mining areas containing multiple deposits amenable to both open-pit and underground mining. A Phase One definitive feasibility study was completed in October 2020 detailing an initial seven-year mine plan with a centralised processing facility and combination of open-pit and underground mining producing approximately 108,000 oz/y.

RCT said of the agreement: “RCT is thrilled to collaborate with Westauz Mining to maximise remote production with the deployment RCT’s latest innovative digital technology. Machine installations are currently in progress, and it won’t be long until they are operating on site.”

Barminco extends relationship with Evolution Mining at Cowal gold mine

Perenti Group’s underground mining business Barminco is to further strengthen its relationship with Evolution Mining, having been awarded a new A$60 million ($42 million) contract to carry out diamond drill work at Cowal Gold Mine operations in New South Wales, Australia.

The four-year contract will see Barminco use state-of-the-art drill rig technology to improve safety, performance and productivity, it says.

It’s the second contract to be secured by Barminco at the Cowal operations in two months, after recently winning a A$520 million underground and development contract.

This latter contract will see Barminco carry out all underground development and production works at the underground mine where it is currently developing an exploration decline.

Last year, the Evolution board and regulators approved the development of the Cowal Underground Mine, which is set to provide a higher-grade ore source that will be blended with the current E42 open pit and stockpile ore. The development is part of the group’s goal of Cowal producing 350,000 oz/y of low-cost gold and extending the operation’s mine life.
