Roxgold Inc, listed on the TSX, has announced that the Bagassi South project at its Yaramoko property in Burkina Faso has been completed approximately 10 % or US$2,8 million under budget and on schedule with the successful practical completion of its process plant expansion. Production from Bagassi South will supplement the existing 55 Zone underground mine at Yaramoko, commissioned in 2016.

The Bagassi South mine, an underground operation, will continue to ramp up during the first quarter of 2019; commercial production is expected to be achieved in the second quarter of 2019.

“We have marked yet another significant milestone in providing growth and value to our shareholders with the successful completion of our internally funded Bagassi South project, which has been completed on schedule and under budget,” said John Dorward, President and CEO of Roxgold. “We are now looking forward to increasing production at Yaramoko and ramping up to full capacity at both the process plant and Bagassi South where we expect to deliver approximately 150 000 ounces of gold from our Yaramoko operations in 2019.”

The plant expansion increases capacity by nearly 50 % from 270 000 tonnes per annum (t/a) or 750 tonnes per day (t/d) to 400 000 t/a or 1 100 t/d. The expansion maintains the simple and robust design philosophy that was implemented originally at the Yaramoko plant which has generated recoveries in excess of 98 %.

The following upgrades were implemented to facilitate the additional throughput and gold recovery: a secondary crushing circuit with a throughput of 100 t/h; conversion of the SAG mill to a ball mill; expansion of the CIL circuit, consisting of two extra adsorption tanks and an additional thickener; and expansion of the gravity circuit via an additional Acacia leach reactor and two electrowinning cells. Additional raw water storage and power reticulation infrastructure has also been provided.

Mine development has commenced at Bagassi South with approximately 668 m of development completed as of the end of November 2018. As previously reported by Roxgold, first development ore was delivered to the ROM pad in October on schedule.
