New Liberty Gold Mine deploys BMT’s blast movement monitoring solution
West African gold producer, Avesoro Resources, has announced that it has deployed BMT’s blast monitoring technology to maximise ore recovery in its New Liberty gold mine, located in Liberia.
“BMT has been working with New Liberty’s geology team to help them understand the dynamics of ore movement and the benefits of properly accounting for movement in every blast,” said Bright Fianu, BMT’s Regional Sales Manager-Africa. “The results so far have been very positive, which we expect to translate into improvements in head grade for the operation.”
“Significant movement occurs within all blasts. Variation of ±50% in horizontal movement is common, and has a significant effect on ore loss and dilution. BMT’s blast monitoring technology enables a more accurate determination of ore/waste boundaries after blasting, and has the potential to significantly increase an operation’s profit. The decision by New Liberty demonstrates the real economic benefit from properly translating ore/waste contacts post-blast.”
Avesoro Resources Inc. Press Release * “Blast monitoring technology, which tracks the effects of blasting on ore movement and heave, was introduced to improve ore blast designs and limit movement during blasting. As a result, bench heights in ore blasts have been reduced to 5m in the Marvoe pit to reduce ore dilution.…Total gold production for the Quarter was 15,825 ounces, an increase of 6% on the prior quarter, and a 91% increase on Q2 2016.”
Serhan Umurhan, Chief Executive Officer of Avesoro Resources, commented: “I am pleased that the optimisations that we have worked hard to implement at New Liberty have resulted in a second consecutive positive quarter EBITDA for New Liberty.”
