Komatsu is readying the unveiling of an all-new underground drilling and bolting product platform with a “bold, industry-disrupting design” that will debut at its first ever virtual livestream event.

On October 26, event attendees will be among the first to experience this new platform, designed after years of working in collaboration with customers to understand the challenges faced by mining operations, the company said.

The first four of 14 planned new drilling and bolting models using the platform will be featured during the event. Two LHDs, one brand new and one enhanced and improved over the current model, will also be unveiled.

In addition to showcasing the new machines, the “Explore beyond the surface: Innovations for hard rock mining” event will offer participants the chance to hear from and ask questions of product experts, Komatsu said. “We’ll share the design considerations that went into each of our new products and the benefits and opportunities that can be expected with their use,” the company added.

Josh Wagner, Vice President Hard Rock at Komatsu, said: “We’re thrilled to finally be able to reveal these new products, which were developed based on the insights we’ve gained by working side-by-side with our customers in the mining industry.

“Our new drilling and bolting platform and LHD machines are the latest examples of our commitment to delivering sustainable, innovative solutions that support our customers’ mining operations.”

Xtract Resources’ wholly-owned Mozambique subsidiary, Explorator Limitada, has concluded a mining contractor agreement with Longhau Tianci Mining Co Ltd for the exploitation of the Guy Fawkes hard-rock gold deposit at its Manica mining concession in Mozambique.

The pact will see Longhau mine the Guy Fawkes deposit for six years or until the orebody is depleted or no longer viable, Xtract says.

Guy Fawkes was mined historically since 1893 and was one of the largest of a series of hard-rock gold mines in the district, with total production of almost 16,000 oz Au reported, Xtract said. A previously reported SAMREC-compliant indicated and inferred resource at Guy Fawkes came out at 1.13 Mt at 1.91 g/t Au with potential for additional upside in several dimensions.

Subject to a number of pre-conditions including the contract miner obtaining a gold trading licence and Explorator securing a mining licence and environmental licence, the agreement includes performance targets whereby Longhau will be required to commission a plant with a minimum throughput of 60 t/d within two months from the date of signing. The throughput tonnage will be increased to 120 t/d within three months of commencing operations, Xtract said.

Explorator will be responsible for recording the gold concentrate produced from the permitted area on a daily basis, while the contract miner will be responsible for the smelting of the gold concentrate and delivery of gold doré bars.

Longhau, as the contract miner, will retain 74% in gold for services provided, and Explorator will retain 26% of all gold production, amounting to 20% after payment by Explorator of the applicable Mining Production Tax of 6%.

After deduction of applicable expenses and costs and tax incurred by Explorator, Xtract has agreed with Mutapa Mining and Processing LDA (MMP), Explorator’s existing hard-rock collaboration partner, to split the net cash flow 65% in Explorator’s favour (with 35% due to MMP).

Xtract Resources, back in 2019, signed up to a collaboration agreement with MMP that could see the building of a carbon in leach plant and the subsequent processing of hard-rock ore from Manica.

Longhau is to commence adit mining and initial underground development during the processing build phase, Xtract said.

Colin Bird, Xtract Executive Chairman, said: “We are pleased to report the signing of this agreement, which should provide the opportunity for incremental cash flow during MMP’s Fair Bride construction and building phase.

“The Guy Fawkes deposit shows considerable variation both in mining width and grade, demonstrating propensity for selective higher-grade mining. Longhau intends to work a portion of the deposit by open-cast methods where drilling indicates that suitable grades locally can run close to surface. Underground mining will be selective.

“We are currently in discussions in respect of the Boa Esperanza deposit and look forward to updating shareholders shortly.”
