Troy Resources has produced the first gold bar weighing more than 4.7kg from the Karouni project in Guyana.
The gold processing plant completed commissioning in late-October and has been running in a stop start mode since then.
At present, the plant is operating between 40% and 50% of capacity, with nominal design capacity of 80,000t per month expected to be achieved in early 2016.
Troy Resources project development executive director Ken Nilsson said: "We are extremely excited to have poured our first gold bar at Karouni.
"The plant is fully functional and we are operating at a level slightly ahead of our anticipated ramp-up programme."
Going forward, the company plans to test the plant's gold processing section from electro-winning through to smelting.
In order to start producing gold from the leach as well as gravity circuits, Troy Resources is now building up carbon loadings.
The plant is currently running with a single furnace enabling a smelting cycle of about three to four days, and the company plans to operate a second furnace after the throughput reaches a steady state.
Formally known as the West Omai project, the Karouni project is located in the central-northern part of Guyana and lies 180km south-south-west of Georgetown.
The project covers an area of 113,581ha and is dominated by gently undulating terrain at elevations ranging from 50m to 100m above sea level.
