Heron Resources Limited (Heron or Company) is pleased to advise that its wholly owned subsidiary, Ardea Resources Limited (Ardea), has completed an independent Resource Statement for the cobalt-rich portions of the Kalgoorlie Nickel Project (KNP).  The KNP Cobalt Zone is a key element of Ardea’s IPO and listing on ASX, planned for February 2017.

The new estimate for the KNP Cobalt Zone is 49.7Mt at 0.12% cobalt and 0.86% nickel, occurring within three separate KNP centres (Table 1).  The global cobalt resource for the full KNP remains unchanged at 805Mt at 0.05% cobalt and 0.7% nickel using a 0.5% Ni cut-off grade[1].

Ardea completed a review of the KNP in late 2016, concluding that the KNP as a whole comprises Australia’s and the developed world’s largest cobalt resource[2].

The KNP Cobalt Zone is located 50-150km north and northeast of Kalgoorlie in Western Australia (Figures 1 & 2), a favoured investment jurisdiction with excellent infrastructure that can facilitate ethical cobalt production for green energy.

Independent firm Ridley Mineral Resource Consulting Pty Limited (RMRC) has reported the following Mineral Resources within the five cobalt-rich prospect areas based on identified zones of continuous elevated cobalt mineralisation using a 0.08 % Co cut-off in these areas:

Vale Inco[3] completed a $34.5 million Pre-Feasibility Study (PFS) on the KNP in 2009 concluding that it is “one of the most prospective nickel laterite tenement packages in the world” and “the KNP tenements form one of the largest potential nickel laterite deposits in the world”. 

[3] Vale Inco has not consented to the use of the PFS in this announcement.

RMRC has prepared the 2017 updated Resource Statement using modified reporting criteria for cobalt abundances in existing resource models that were previously prepared by Snowden Mining Industry Consultants (Snowden) and Heron.

This update describes the current publicly reported Mineral Resources for five prospect areas within the KNP known to contain cobalt-rich mineralisation.  Two of the estimates, completed by Snowden in 2004, formed part of Heron’s early assessment of the Scotia Dam and Black Range prospect areas. 

Estimates for the Goongarrie South and Big Four prospects were completed by Heron in 2009 as part of a KNP PFS update following an initial PFS completed by Vale Inco in 2009.  The current estimate for Aubils was by Heron in 2008 as part of feasibility assessment of the Yerilla Nickel Project. 

The KNP Cobalt Zone is associated with a distinctive geo-metallurgical type defined as “Clay Upper Pyrolusitic”.  Mineralogy is goethite, gibbsite and cobaltian pyrolusite (strictly “asbolite” or “cobaltian wad”).  Each of the cobalt-rich zones typically occurs as a sub-horizontal body (Figure 4) at a palaeo-water table within the KNP (and developed as a late stage supergene enrichment).  This material is particularly well developed at Goongarrie South, which will be the focus area for Ardea’s cobalt development studies.

Figure 2 – Ardea Resources Limited, Project Locations showing KNP Cobalt Zones and regional infrastructure 

Based on the contained cobalt metal within the deposit, the KNP is Australia’s largest cobalt deposit (Table 2, Figure 3).  By this measure, it is more than three times larger than Australia’s second largest cobalt deposit.  The newly-defined cobalt resource from the high-grade KNP Cobalt Zone is a subset within the larger KNP resource, and the subset by itself is Australia’s fourth largest cobalt resource.  The KNP Cobalt Zone also is amongst the highest cobalt grades in Australia (Tables 2 & 3).  In terms of global cobalt resources, the KNP is the premier resource within stable western jurisdictions.

The updated resource reporting for cobalt-rich zones provides a basis for KNP remodelling work planned by Ardea that is focused on cobalt grade shells.  Quantifying the cobalt-rich mineralisation at the KNP marks the first part of a refocussing for the KNP onto the cobalt component of the deposit.  

Forthcoming drilling and metallurgical studies will move the KNP towards a PFS focussing on cobalt-nickel-manganese feedstocks for the lithium ion battery industry (Lithium Nickel Manganese Cobalt Oxide - LiNiMnCoO2 or NMC).

COMPLIANCE STATEMENT (JORC 2012 and NI 43-101)

A competent person’s statement for the purposes of Listing Rule 5.22 has previously been announced by the Company for:

1. Kalgoorlie Nickel Project on 21 October 2013 and 31 June 2014, 27 August 2015, 2015 Heron Annual Report, 27 October 2016, 2016 Heron Annual Report, Ardea Resources Limited Prospectus 9 November 2016; Ardea Resources Limited First Supplementary Prospectus 18 November 2016.
2. Big Four-Goongarrie on 13 March 2012, 26 June 2012 and 24 July 2012. 

The Company confirms that it is not aware of any new information or data that materially affects information included in previous announcements, and all material assumptions and technical parameters underpinning the estimates continue to apply and have not materially changed.  All projects will be subject to new work programs following the listing of Ardea, notably drilling, metallurgy and JORC Code 2012 resource estimation as applicable.

The information in this report that relates to Exploration Results is based on information originally compiled by previous and current full time employees of Heron Resources Limited.  The Exploration Results and data collection processes have been reviewed and verified by Mr Ian Buchhorn who is a Member of the Australasian Institute of Mining and Metallurgy and currently a full-time employee of Heron Resources Limited.  Mr Buchhorn has sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the exploration activities undertaken to qualify as a Competent Person as defined in the 2012 Edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’.  Mr Buchhorn consents to the inclusion in this report of the matters based on his information in the form and context that it appears.
