Some of the highest grade copper intersections to date have been confirmed at Marengo Mining’s Yandera project during an infill drill program. Some of the intersections include 126 metres @ 0.92% copper and 700ppm molybdenum from 30 metres and 150 metres @ 0.68% copper and 198ppm molybdenum from 87 metres.
The results are significantly higher in grade than the average grade of the current measured and indicated resource of 0.43% copper. Marengo says the results provide further strong evidence of the presence of high-grade, near-surface zones which are expected to enhance mining revenues from the early years of the targeted 20 year Yandera operation.
The diamond drilling was completed at the Omora and Imbruminda zones where 145,000 metres of drilling has taken place as part of resource definition exploration.
Marengo’s managing director Les Emery says he’s excited by the new results. “The recent drilling has returned individual intersections of up to 186 metres and grades in some instances of close to 1% copper – double the average resource grade of the project and among our best ever drill results.
“These intersections provide further evidence of the potential of Yandera. The high-grade ‘starter’ zones we continue to delineate are of great strategic importance to the project, as they have the potential to enhance returns in the early years of operations and accelerate capital payback.”
Marengo’s flagship Yandera copper-molybdenum-gold project is in Madang province and hosts a measured and indicated 362 million tonnes @ 0.43% copper.
