Those sales forecasts are based upon BBM's ramp-up of saleable production, which has been agreed with the mining contractor.

"Forecast sales are sales comprised of a combination of domestic and export sales, depending on the best price realisation for Cokal," it said.

Cokal's domestic offtake partner PT Sumber Global Energy is responsible for sending its barges to Batu Tuhup to collect Cokal's coal.

Under the terms of the offtake agreement with SGE, Cokal gets 50% of the payment for the coal upon their barges arriving at the Batu Tuhup Jetty, an additional 40% upon the coal being loaded onto their barges and the final 10% when documentation is finalised.

While SGE remains contracted to buy coal for the domestic market it has not provided any sales at this point due to its concentration on other thermal coal projects.

"This has not impacted Cokal's sales opportunities as there are a number of parties both domestic and international seeking BBM product," Cokal said.

"The underlying financial arrangement is based on SGE's coal sales only and, as such, does not affect Cokal's financial and coal sales profile."
