Australian-based Enerji has signed a memorandum of understanding (MoU) to develop its accretive thermal energy node (ATEN) solutions for Resolute Mining’s Syama gold mine in Mali, West Africa.

Under the MOU, both companies will investigate the potential for the ATEN technology to deliver operational cost savings through capture and conversion of waste heat generated at the Syama mine.

Resolute Mining managing director and CEO John Welborn said: "We are pleased to be working with Enerji on this potential cost saving innovation as part of our ongoing focus on efficiency and environmental responsibility.

"The sulphide processing plant at Syama includes a roaster, which produces a significant thermal signature, creating an opportunity for Enerji to adapt its technology."

"We are pleased to be working with Enerji on this potential cost saving innovation as part of our ongoing focus on efficiency and environmental responsibility."

Enerji’s new technology uses the modular organic rankine cycle (ORC) system, which can be deployed easily.

Using the ORC, ATEN will be able to harvest low-grade heat to produce electricity by way of a capture and conversion process that produces zero emissions.

Enerji CEO Andrew Vlahov said: "The agreement with Resolute is another positive step towards Enerji’s transformation to provide innovative energy solutions for clients in domestic and overseas markets.

"Our preliminary analysis indicates that the ATEN system can be adapted to Syama to deliver strong commercial outcomes for Resolute and Enerji."

The Syama mine is located about 30km from the Côte d’Ivoire border and 300km southeast of the capital Bamako, and has two sulphide and oxide processing plants with site production capable of more than 250,000oz/pa.

Gold mining company Resolute currently operates the Syama gold mine in Africa and the Ravenswood gold mine in Australia.
