Gem Resources PLC (LSE:GEMR) said it is optimising the operations of its Gravelotte emerald mine in South Africa as it moves towards phase two of the restart operation.
Phase one has been underway for approximately six months, Gem added, during which period approximately 5,500 tonnes of ore was processed, primarily sourced from tailings and stockpiled materials.
Several key items and opportunities to enhance operational efficiency were also highlighted.
To capitalise on these opportunities, Gem said two local engineering firms have been appointed to modify components within the processing plant to boost production capacity improve recovery rates, and minimise delays caused by equipment downtime.
Once these upgrades have been completed, GEM will initiate active mining in both the Cobra and Discovery open pits.
This is a critical step in the phase two production ramp-up, it added, both to improve the quality of the emeralds recovered and establish a steady supply of high-grade ore.
Chairman Ed Nealon added that phase one of Gravelotte's restart demonstrated the mine's potential to resume its historic position as a major source of emeralds.
“The upgrades and equipment additions will improve recovery rates and minimise production delays.
“As part of the start-up phase, we were hoping to conduct a small trial sale in late September, but due to circumstances beyond our control, we are unable to do so.
“We are currently looking at options to conduct a trial sale in the near future while we continue to stockpile material.”
