JOHANNESBURG (miningweekly.com) – Gold miner Troy Resources advised shareholders on Friday that gold production at its Karouni mine, in Guyana, would be at the lower end of its guidance for 2016, owing to ongoing disruptions in the milling circuit.
The company explained that contaminated lubrication oil was found to be the cause of frequent mill trips at Karouni.
“It appears the contamination of the oil is the result of the ingress of small amounts of very fine particles entering the trunnion bearing housing due to spills caused by transfer chute blockages at the mill feed end and the subsequent clean-up using high-pressure water sprays.”
Troy said that the issue had been addressed by installing a protective roof over the trunnion and better sealing of the inspection hatches.
“Every effort will be made to try and make up for this situation in the second half of the year,” the company added.
Karouni’s production guidance for the 2016 calendar year is between 100 000 oz and 120 000 oz.
