ASX announcement

Mastermyne Group Limited Recommencing Roadway Development at South32’s Illawarra Coal

Mastermyne Group Limited (ASX Code: MYE) (“Mastermyne” or “the Company”) is pleased to announce that it will restart roadway development services at South32’s Illawarra Coal Operation. This scope of work was previously deferred by South32.

The recommenced contract scope is for the provision of mine roadway development services, which is expected to deliver annual revenues of approx. $18 million. The contract term of two years will be delivered as a variation under the Group’s existing contract with South32.

The additional revenue generated through this contract secures the upper end of the recent FY19 guidance range. The Company looks forward to updating guidance over the course of the financial year as further opportunities are converted from Mastermyne’s record pipeline.

Mastermyne CEO, Tony Caruso, said “We are very pleased to have recommenced work on this project and further extend our working relationship with South32’s Illawarra Metallurgical Coal operations. We look forward to delivering safe and productive outcomes for South32 and providing long-term stable work for our employees.”
