The company delivered 4200 tonnes of coal via barge to Cahaya Fajar power station in East Kalimantan on schedule.
Kangaroo sold the coal as part of a competitive tender process, enabling it to supply greater volumes in the coming months as the project ramps up.
GPK will produce 100,000t per month by early 2011, ramping up to 3-4Mtpa by 2012.
Development of site infrastructure will continue into the first half of this year.
Kangaroo is also boosting its coking coal prospects, beginning preliminary operations at its recently acquired Mamahak project.
Initial production targets of up to 30,000tpm are scheduled from the project while the company conducts further test work.
Production of up to 1Mtpa from Mamahak, together with the adjacent Jawana and Borami projects, are expected in the long term.
Kanagaroo is also negotiating the sale of a 30,000t coking coal stockpile at Mamahak that was acquired when the company bought the operation.
Kangaroo’s shares are up 4.7% this morning to 22.5c.
