Australia-based Troy Resources has commissioned the processing plant at Karouni gold project in Guyana.
According to the company, construction activities at the plant began in February and all parts have been dry and wet commissioned over the past six weeks.
During the process, the mill underwent an extended performance test and is being fed with a limited amount of ore at present in order to enable pressure and flow-rate adjustment to all systems.
Troy Resources managing director Martin Purvis said: "Conclusion of commissioning activities represents a significant milestone in the fast-track development of Karouni and I congratulate all the employees and contractors who have worked together safely and tirelessly to achieve this outcome, within very challenging physical conditions.
"If the ramp-up in production continues as expected, the first gold pour is now expected to occur in the first half of November."
The last part of the elution circuit, which has been programmed, will be ready to operate soon.
Troy Resources stated that ore feed will steadily be increased towards the plant's design capacity of about 80,000t per month once the final adjustments are done to the mill and processing circuits. This is expected to be achieved by next year.
The mining operations are going ahead without incidents and the facility has been commissioned, the firm stated. As a result, the run of mine (ROM) stockpile already comprises 137,000t of ore at an average grade of 2.41g/t.
Previously known as the West Omai, the Karouni Project lies about 180km south-south-west of Georgetown and covers an aggregate area of 113,581ha.
