Mastermyne lines up Crinum operator role

Mastermyne lines up  Crinum operator role Queensland Mines Rescue Service shared this photo of the re-entry on LinkedIn.

Mastermyne Group is continuing as mine operator at the Crinum underground site while owner Sojitz Blue finalises strategy and investment approval on a proposed restart of operations there.

An underground mining services contract with Mastermyne, including provision of equipment, is under negotiation as part of that process.

Sojitz Blue acquired the Gregory Crinum complex near Emerald from BMA in 2019 and is currently mining from the Gregory open-cut area, while investigating the viability of restarting mining in the previously sealed Crinum underground area.

Mastermyne was appointed to undertake a feasibility study focusing on the development of a high productivity bord and pillar mining operation.

In parallel, Mastermyne was also engaged as the mine operator to undertake the re-entry process, including commissioning of a ventilation system and water management for the inspection of the underground environment and conditions.

Mastermyne successfully re-entered the underground mining area in
late October, in conjunction with the Queensland Mines Rescue Service, with no major issues encountered. (See previous story HERE)

“The re-entry of the underground workings and appointment as the mine operator are very significant milestones for Mastermyne’s business growth strategy,” Mastermyne chief executive officer Tony Caruso said.

“We are very pleased to be working with Sojitz and we look forward to the mine moving into production.”

The Crinum deposit offers an initial resource of about 14 million tonnes to be mined via a bord and pillar operation, before transitioning to M Block – with an 80 million-tonne resource.

The underground restart remains subject to approval from Sojitz Blue parent company Sojitz Corporation.
