Ausdrill says it has just commissioned the first of four new Caterpillar MD6250 drills at the Boggabri coal operations in New South Wales, Australia.

The machine has been successfully commissioned on site four weeks ahead of the contract start date, according to the Perenti company, with the help of the WesTrac team at Tomago, NSW.

These M6250 drills come with the next level of drill automation and driller assist, Ausdrill says, including one touch auto levelling and auto drilling functions combined with Cat MineStar Terrain for drilling to improve safety, productivity, reliability and accuracy.

Back in February, Perenti reported its Surface Mining Industry Sector Group had been awarded A$155.5 million ($113 million) in new and extended contracts. This included a three-year contract (with options to extend) for production drilling services with Boggabri Coal Operations (a part of Idemitsu Australia Resources Group) at Boggabri.

The MD6250 is designed for both down-the-hole drilling in hard rock and rotary drilling in softer rock. The blasthole drill carries out single-pass drilling and multi pass, as well as angle drilling, according to Cat.

MACA is currently running an MD6250 at the Bluff coal mine, in Queensland, while AngloGold Ashanti Australia, with support from Flanders and Tropicana Mining Alliance partner, Macmahon Holdings, now has five autonomous Cat MD6250 drill rigs as part of its drilling fleet at the Tropicana gold mine, in Western Australia. Thiess, Cat and WesTrac have also introduced an MD6250 drill rig with autonomous drilling capability at Mount Pleasant, in New South Wales, in a phased 12-month pilot project.

Barminco says it has mobilised to start the development of the new underground portal at Barrick Gold’s Hemlo gold mine in Ontario, Canada.

The installation of the portal ground support has been completed and a new Sandvik DD421 jumbo is being used to drill the first round of what will be the entrance to the new decline ramp, Barminco said.

It added: “Barminco is proud to be introducing high speed development capabilities at Hemlo, adding value to the already well-established mine.”

Earlier this year, Barminco was issued a letter of intent to provide underground contract mining services at Hemlo following Barrick’s decision to phase out open-pit mining and move to an underground contract mining model at the operation.

Perenti, Barminco’s parent company, said back then that its underground contract mining division would “bring industry-leading technology and productivity to Hemlo in support of Barrick’s goal to modernise and improve the performance of the mine and establish it as a Tier Two asset within its group”.

Having become the first company globally to have taken delivery of a mobile raiseboring machine with uphole, downhole, and back reaming capability, Barminco is transporting a Rhino 100 Raise Borer to another client site in Australia.

With the help of its Perenti surface mining partner, Ausdrill, the newest addition was recently transported to Regis Resources’ Rosemont gold mine in Western Australia.

Just last year, Barminco sealed a three-year underground mining services contract with Regis at Rosemont, which has been transitioning from open-pit to underground mining at the operation.

Barminco said: “Through safe and rapid mobilisation, we are able to meet our clients’ needs and transport our equipment across multiple sites to complete a range of drilling campaigns.”

Since April 2019, Barminco’s first Rhino has travelled a combined 15,000 km between four client sites in the Goldfields of Western Australia, drilling a total of 3,843 m.

The Rhino is manufactured by TRB-Raise Borers in Finland but is equipped with Sandvik tools and is distributed by Sandvik. It is a fully mechanised and self-contained electro-hydraulic mobile raiseborer designed for slot raising in underground mining. The latest models also have an optional back reaming module.

In addition to helping transport Barminco’s latest Rhino to Regis’ site, Ausdrill has recently added a new Boart Longyear LF™160 drill rig and FREEDOM™ Loader combination to its diamond drilling fleet.

This rig reduces the crew’s “Hands On Steel” interaction, while improving overall safety standards, Ausdrill said.

When paired with the FL262 FREEDOM Loader, the LF160 combination is ideal for contractors who want to target sophisticated surface drilling exploration contracts that stipulate some of the highest safety standards, without compromising on productivity, Boart Longyear says.

Perenti subsidiary, African Underground Mining Services (AUMS), has been awarded a contract extension at Roxgold’s Yaramoko mine in Burkina Faso.

The contract extension is valued at around A$200 million ($146 million) over two years, from December 2021 to December 2023. It follows on from the existing development and production scope currently being executed, taking the total contracted work-in-hand at Yaramoko to some A$350 million as at the end of August 2020, Perenti said.

AUMS is an operating business unit of Barminco and has been successfully operating at the mine since the development of the Zone 55 portal in 2015. The project, 200 km southwest of Ouagadougou, has now grown to include the Bagassi South mine.

In the June quarter, Yaramoko produced 32,812 oz of gold, according to Roxgold.

Barminco’s Chief Executive Officer, Paul Muller, said: “The high-grade Yaramoko complex is an important project for Roxgold, Barminco and the people of the Yaramoko community. We are very pleased to extend our contract with Roxgold to December 2023 and look forward to continuing to create enduring value and certainty for our client, employees, shareholders and the people of Yaramoko and Burkina Faso alike.”

Perenti Managing Director and Chief Executive Officer, Mark Norwell, said Barminco and AUMS, combined, are a global leader in hard rock underground mining, with this contract extension reinforcing this sector leading position.

Base metals, Mineral project development, Mining services, , , , , , , , ,

Perenti’s hard-rock underground miner Barminco has been awarded a development and production contract at Western Areas’ Odysseus mine, in Western Australia.

The contract at Odysseus, part of the Cosmos nickel operation, is valued at around A$200 million ($146 million) over five years and follows on from the earlier rehabilitation works completed by Barminco at the mine.

Western Areas acquired Cosmos in October 2015 and commenced the redevelopment of Odysseus in January 2019. Once in production, Odysseus is expected to produce 14,000-15,000 t/y of nickel concentrate, becoming Western Areas third nickel mine in Western Australia.

Western Areas Managing Director, Dan Lougher, said today (September 8) that excellent progress had been made on the underground and surface infrastructure works at Odysseus, with minimal COVID-19 impacts.

“We have reached a critical milestone with the firing of the full-face development of the Odysseus decline, which is now heading across to the orebody,” he said. “A significant amount of preparation and support work has been delivered across the site to reach this milestone.

“We now have our eye on the delivery of the first ore tonnes mined from underground in the first quarter of financial year 2022.”

Barminco’s Chief Executive Officer, Paul Muller, said the company was excited to continue its relationship with the Western Areas team, which began in 2005 at the Forrestania mine and has now grown to include the Cosmos nickel operation.

“Odysseus is a significant project to bring on-stream, and the five-year term demonstrates the trust and confidence Western Areas has in Barminco to continuously improve and deliver for them,” he said.

OEM-agnostic autonomous solutions specialist RCT says it has executed a project with Perenti-owned African Underground Mining Services (AUMS) at the Siou underground gold mine, in Burkina Faso.

Earlier this year, RCT commissioned its ControlMaster® Guidance Automation technology on two of Siou’s Caterpillar R2900G underground LHDs and supplied two associated Automation Centres.

Siou, owned by SEMAFO, is a gold deposit some 20 km from the Mana mine. Conversion of Siou open pit into underground mining operations began in the September quarter of 2018 with full underground production expected shortly, according to SEMAFO.

Guidance Automation enables the loaders to operate with minimal intervention by machine operators located in the Automation Centres, either on the surface of the mine or in a secure location in the underground mine, RCT said.

“The automation solution improves safety onsite by relocating mine personnel away from the mine face and reducing unplanned maintenance downtime by eliminating machine operator errors,” RCT said.

RCT says its Africa-based staff has provided comprehensive training to machine operators and will continue to provide ongoing after-sales support to AUMS.

West African Resources says it has processed the first ore at its Sanbrado gold project in Burkina Faso, putting it on course to produce its inaugural gold product within the next month.

Construction activities have now been completed on all areas of the process plant and tailings storage facility, according to the company.

All four heavy fuel oil generators have been commissioned in the power station and are now operational, while the desorption and gold room circuits are undergoing commissioning in preparation for a maiden gold pour within the next four weeks.

Open-pit mining contractor, African Mining Services, a subsidiary of the Perenti Group, has ramped up mining activities to include both the M5 and M1 South pits, with day and night shifts starting in the past week, West African said.

Currently, over 360,000 t of oxide ore is stockpiled on the run of mine pad at an average grade of 1.5 g/t Au.

Underground development continues to progress on-schedule with mining contractor Byrnecut Offshore, a subsidiary of the Byrnecut Group, having completed the primary ventilation raisebore. The ventilation fan is also currently being installed. First development ore remains on track for late March and first stoping ore is forecast for the September quarter, the company said.

West African Executive Chairman, Richard Hyde, said: “This is a major milestone for West African Resources and testament to the quality of our team and contractors. Commissioning activities will continue over the next four weeks with the first gold pour on track for early Q2 (June quarter) 2020.”

An updated feasibility study on Sanbrado from 2019 envisaged an initial 10-year mine life, including 6.5 years of underground mining, with probable reserves of 1.7 Moz (21.6 Mt at 2.4 g/t gold). The project was expected to have average annual production over the first five years of 217,000 oz gold with all-in sustaining costs of less than $600/oz.

In response to media speculation, Perenti has confirmed it is “currently giving consideration” to the potential purchase of Downer EDI’s mining services division.

“The process is ongoing and Perenti would only put forward an offer to acquire the business if it were to align with its strategy and deliver value for the company’s shareholders,” it said.

Downer confirmed in November that it would be undertaking a portfolio review “to determine whether there are opportunities to enhance the alignment” of its portfolio, noting that an important area of focus for the review was the mining business.

Perenti, a global mining services firm, has expanded substantially in the past few years, acquiring Barminco in late 2018 to become Australia’s second-largest mining services company.
