Keras Resources said it had started trucking of processed ore from its bulk-sampling metallurgical testwork programme at the Nayega manganese project in northern Togo.
Steady-state production levels of 230 saleable tonnes per day had been achieved through a recently-commissioned scrubber plant.
Peak haulage of 12 trucks, or 420 tonnes per day, was expected by 31 January 2019.
'The continued success of the bulk sampling programme has underpinned the significant value that we attribute to Nayega,' chief executive Russell Lamming said.
'We believe the project will form the cornerstone of Keras' manganese business moving forward.'
