    Positive Metallurgical Update on Cardinal Resources Namdini Project

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

    • 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:

    o increased gold recovery (Table 1)

    o coarser regrind size compared with the current flowsheet

      • reduced power consumption (ie lower installed power requirements and Opex)
    • o improved mass transfer of oxygen and reactivity of reagents
      • reduced reagent consumption leading to reduce operating costs

    o 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
