Gem Resources, formerly URA Holdings, has processed about 5,500 tonnes of ore, primarily sourced from tailings and stockpiled materials, as part of Phase 1 of the restart at the Gravelotte emerald mine in Limpopo, South Africa.
The company, which commenced Phase 1 of the Gravelotte restart in the first half of the year, said the progress made demonstrates 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,” said Gem Resources chairperson Ed Nealon. “We are currently looking at options to conduct a trial sale shortly while we continue to stockpile material.”
The material processed in Phase 1 has mainly been from stockpiles and tailings, while some material removed as part of the preparation for the start of mining activities in both the Cobra and Discovery open pits was also processed.
Gem Resources says preparations for the start of mining in the Cobra and Discovery open pits have been successful, with material cleared and access roads now completed in preparation for the start of mining activities at Level 8 in the Cobra pit and Levels 1 and 6 in the Discovery pit.
Gem Resources said it will initiate active mining in both the Cobra and Discovery open pits upon completing the planned processing plant upgrades.
This next phase will be a critical step in further ramping up production, improving the quality of the emeralds recovered, as well as establishing a steady supply of high-grade ore for processing, it said.
