According to Mining News Pro -  "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 oz of gold from our Yaramoko operations in 2019."

The plant expansion increases capacity by nearly 50% from 270 000 tpy or 750 tpd, to 400 000 tpy or 1100 tpd. 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 tph;
    Conversion of the SAG mill to a Ball mill;
    Expansion of the carbon-in-leach (CIL) circuit, consisting of two extra adsorption tanks and an additional thickener;
    Expansion of the gravity circuit designed to recover 70% of head grade consisting of an additional Acacia leach reactor and two electrowinning cells; and
    Additional raw water storage and power reticulation infrastructure.

Mine development has commenced at Bagassi South, the second high grade underground mine at Yaramoko, with approximately 668 m of development completed as of the end of November 2018. As previously reported, first development ore was delivered to the ROM pad in October on schedule. Ramp-up of the mine will continue during 1Q19, with commercial production expected to be achieved in the 2Q19.    
Regional exploration

Drilling recently commenced at Kaho, located at the southern end of the 55 Zone-Bagassi South Corridor. The RC drilling is testing a >1.5 km coincident geochemical and geophysical anomaly defined last season, and which is also located in an interpreted favourable structural position. Preparations are also underway for additional auger drilling in the first quarter of 2019 to extend the Kaho grid further south.

In addition, five drill rigs continue to drill at the 55 Zone focused on infill and extensional drilling of the deposit, with results continuing to support the model.
