Perth, Australia, Mar 21, 2017 - (ABN Newswire) - Cardinal Resources Limited (ASX:CDV.AX - News) (OTCMKTS:CRDNF - News) ("Cardinal" or "the Company") is pleased to report a second interim metallurgical update for the Namdini Project ("Namdini").
- A number of conventional gold recovery improvement techniques are showing that overall gold recoveries of 84% are easily achievable.
- A conventional crush-float-fine grind-CIL flowsheet continues to be the preferred processing option, which allows for a low mass flotation concentrate with superior operating costs due to low volumes of high grade concentrate to be processed
Cardinal Resources Project Technical Manager Julian Barnes said:
"We have undertaken further optimisation testwork on the master composite sample reserves that remained from the 2016 metallurgical programme and these have shown a significant improvement in overall gold recovery to 84%. Further optimization testwork is ongoing.
"The objective of this recent optimisation test work was to investigate the possibility of improving overall gold recovery with the main focus on the following:
- Optimising the leach residence time; and
- Pre-leach aeration."
Cardinal's Project Manager, Bruce Lilford said:
"This baseline result is extremely encouraging for our next phase of testwork which will target a significantly higher improvement in overall recovery."
"Independent Metallurgical Operations (IMO) in conjunction with Oreway Mineral Consultants (OMC - a subsidiary of Lycopodium) from Perth, Australia have recently been contracted to develop a metallurgical programme which is representative of the entire Namdini deposit. The resulting report from this new programme is due during Q3 2017 and will be of a level sufficient to complete a feasibility study."
Cardinal's CEO / MD, Archie Koimtsidis said:
"This second round of interim results from the 2016 NMDD005 master composite has demonstrated further significant improvements as part of our ongoing metallurgical optimisation programme.
"We anticipate further improvements in overall recoveries as we continue with the testwork, in addition to growing the maiden resource of 4Moz in both size and confidence categories."
