Aim-listed Edenville Energy has increased the run-of-mine (RoM) coal production at its Rukwa coal project, in Tanzania, by 80% during November.
The company also reported a 10% increase in washed coal production from the October level and said it had had about 1 000 t of washed coal sales.
Orders of 3 600 t of coal for December were placed, and delivery has been confirmed from two large customers.
In November, the company mined 4 026 t of RoM coal versus 2 240 t in October, representing an 80% increase. About 1 125 t of washed coal was processed through the company's wash plant, representing an increase of 10% from the October figure of 1 024 t, which had benefited from historic stockpiles.
A further 18 690 t of waste was also moved, opening up greater access to the coal deposit for future mining.
However, Edenville on December 1 said November's production would have been significantly higher had it not been for extended mechanical issues with the main excavator, which it was unable to use for mining for 15 days while initial repairs were made.
It was subsequently used for the installation of culverts and the clearing of drainage channels to prepare the site for the wet season.
These operations have been completed and the excavator has restarted full mining operations.
Assuming the excavator is operational throughout December, the company believes it should be able to improve substantially on November's RoM coal production figures.
