Cardinal Resources provides positive metallurgical update on Namdini

Cardinal Resources Limited (ASX/TSX: CDV) is pleased to announce a positive development with respect to its metallurgical optimisation testwork activities. As a result of positive leach results, which are expected to enhance the project economics, further laboratory testwork has been initiated.

HIGHLIGHTS

·       Positive leach recovery results reported from Aachen TM pilot scale testwork

·       AachenTM is a relatively simple, proven process being used by a number of successful gold producers globally and specifically in Africa. These operations have consistently demonstrated an uplift in gold recoveries with AachenTM

·       AachenTM results on Namdini flotation concentrate indicates the following potential improvements:

·       increased gold recovery

·       coarser regrind size compared with the current flowsheet

·       reduced power consumption (ie lower installed power requirements and Opex)

·       improved mass transfer of oxygen and reactivity of reagents

·       reduced reagent consumption leading to reduced operating costs

·       expected reduction of both Capex and in particular, Opex

·       Cardinal has already tested 4,447 kg (>4 tonnes) comprising 7 pilot scale composites from 47 drill holes (Table 2) across the entire deposit. Cardinal is finalizing the testwork programme with a further 2,310 kg (>2 tonnes) of samples from an additional 24 drill holes

·       Final AachenTM testwork is in progress to further support the results received to date for potential inclusion into the Namdini Feasibility Study

Peter Lotz, Gold Process & Environment Manager, Maelgwyn Mineral Services Africa, stated: “Our AachenTM process is currently deployed at 9 different mine sites in 6 countries, with the longest service life of over 10 years on one of the largest bullion producers within the African continent.

“We’ve seen our process increase gold recoveries between 2% and 19% in gold producing operations. Former Randgold Resources (now Barrick), a major client of MMS, is using AachenTM equipment at its Loulo and Morila mines in Mali, at its Tongon operation in Côte d’Ivoire, and at the Kibali gold mine in the Democratic Republic of Congo.

“We look forward to our continuing work with Cardinal in this regard.”

Cardinal’s Chief Executive Officer / Managing Director, Archie Koimtsidis stated: “These highly encouraging results from the metallurgical optimisation programme are potentially an opportunity to further enhance the Namdini project financial outcomes and should be incorporated into the process flowsheet being designed by Lycopodium.

“The metallurgical optimisation test results recently received and evaluated show promising recovery, capital and operating cost improvements, which can be achieved over and above the current outcomes justifying incorporation into the Feasibility Study.”
