Newfield sees opportunity to develop Tongo D-1 kimberlite from 2023

08 october 2019

newfield_resources_logo.pngNewfield Resources has seen an opportunity to develop the Tongo D-1 kimberlite, in Sierra Leone from 2023 in parallel with planned mining of the Kundu and Lando kimberlites.
Company managing director Karl Smithson said they had decided to adopt a plant design, which will enable rapid modular expansion from 50 tph to a nameplate 100 tph capacity.  
“This provides the potential for significantly expanded production rates from 2023 and also delivers the flexibility to further increase production from existing and other kimberlites that are not yet in the broader mine plan,” he said.
Meanwhile, Smithson said drilling and assaying of the Panguma kimberlite, located in the west of the Tongo D mining licence area, is delivering positive results.  
The key initial objective at Panguma is to delineate a JORC-compliant resource and hence increase the overall resource inventory of the Tongo Mine Development from its current 7.4 million carats.
So far eight holes (for 574 metres) have been drilled, with all holes intersecting the Panguma kimberlite. 
It is envisaged that a further four holes will be drilled and then samples of kimberlite core will be consigned to the Saskatchewan Research Council (SRC) for further microdiamond analysis and grade estimation.
Newfield has also completed the blasting of the boxcut for the portal access to the underground declines at Tongo.
Work is now focused on providing the necessary support of the boxcut and shaping of the haul road to attain the right angle of entry into the decline.
