Newfield makes ‘strong’ progress at Tongo diamond project

02 july 2018
Newfield Resources, which merged with Stellar Diamonds last April, said it has made “strong” progress at its flagship Tongo diamond project in Sierra Leone with the front end engineering (FEED) programme on track for completion in the fourth quarter.
The FEED, said Newfield, would more precisely define the technical requirements of the Tongo project and deliver an optimised underground mine design and treatment plant layout.
This work would also refine the final capital expenditure estimate and operating cost budgets for the project.
Company executive director Mike Lynn said a mine development drilling campaign, running alongside the FEED programme, would be concluded next month.
“This drilling campaign will also result in an updated Mineral Resource estimate for the project later in the year,” he said.
“…we remain firmly focussed on the rapid progression of the Tongo Diamond Project towards being the next diamond mining operation in Sierra Leone.”
The drilling campaign was aimed at delineating the geological nature and morphology of the Kundu, Lando and Tongo kimberlites within the first two levels of planned underground mining of each kimberlite.
About 95 drill holes had been completed to date for 8,206 metres and kimberlite was intersected in 87 holes.
