Grangesberg NI 43-101 Resource Estimate

Anglesey Mining plc 29 September 2014 LSE:AYM Grangesberg NI 43-101 Resource Estimate Anglesey Mining plc ("Anglesey") is pleased to report that Grangesberg Iron AB("GIAB") has received an NI 43-101 Technical Report from Roscoe PostleAssociates Inc ("RPA") showing a compliant resource estimate for theGrangesberg Mine. In May 2014 Anglesey announced that it had entered into agreements giving itthe right to acquire a controlling interest in the Grangesberg Iron project incentral Sweden including a direct 6% interest in GIAB and an option exercisableuntil 30th June 2015 to acquire an additional 51% in GIAB. Anglesey alsoentered into shareholder and cooperation agreements such that during the termof the option Anglesey holds management control and operatorship of GIAB andhas appointed three out of five directors to the board of GIAB including theChairman. The Technical Report which was prepared by RPA and was dated 26th Septembercontains the following summary table: Mineral Resource Estimate Summary - August 22, 2014 Grängesberg Iron AB - Grängesberg Iron Mine Category Tonnes %Fe %P Contained Fe (tonnes) Indicated 115,200,000 40.2 0.78 46,300,000 Inferred 33,100,000 45.2 0.91 15,000,000 Notes: CIM definitions were followed for Mineral Resources. The values for tonnages, grades and contained iron have been rounded. Mineral Resources are estimated at a cut-off grade of approximately 20% Fe. A minimum mining width of approximately 10 m was used. RPA concluded that the Grängesberg iron ore deposit hosts a significant ironresource that has excellent potential for expansion at depth. Geophysicalinterpretations from the 1960s suggest that the ore body continues to at least1,700 m below surface. Diamond drill holes confirm the mineralization continuesto at least 1,100 m to 1,200 m below surface. In RPA's opinion, moregeotechnical, metallurgical, and other engineering studies are warranted toadvance this Project. "We are very pleased with the compliant resource estimate contained within theRPA report", said Bill Hooley, Chief Executive of Anglesey, "This confirms ourbelief in the inherent fundamentals of Grangesberg and we look forward tomoving the project through the next development stages with a target ofrestarting production around 2018 when we believe that the global iron oresupply-demand will be in a more balanced position than currently. We remainencouraged by the support being shown for the project at all levels in Sweden." A programme is currently being developed to look closely at geo-mechanical andhydro-geological aspects of the site which will be critical components of thepermitting regime required for the dewatering and reopening of the mine. Theprincipal consultant who will oversee this work has commenced activities;drilling quotations have been obtained; and permit applications for thenecessary work have been submitted to the relevant authorities. Theseactivities will include drilling boreholes into the general mine area and thecapture and interpretation of key data on the physical aspects of the groundand hydrological conditions. It is expected that all the drilling and analysiswill be completed during the autumn and will allow the first stage of permitapplications for mine development to be prepared and submitted. The full RPA report can be found at https://app.box.com/GIABreportSep14 and will also be published shortly on the Anglesey website at www.angleseymining.co.uk The Annual General Meeting of Anglesey will be held at 11am on Tuesday 30thSeptember at the offices of DLA Piper, 1 London Wall EC2Y 5EA, London.Shareholders are invited to attend. About Anglesey Mining plc Anglesey is also carrying out exploration and development work at its 100%owned Parys Mountain zinc-copper-lead deposit in North Wales, UK where a JORCCode-compliant resource of 2.1mt at 6.9% combined base metals in the indicatedcategory and 4.1mt at 5.0% combined in the inferred category was published inNovember 2012. The Company has received a detailed review of the resource basefor the entire site which has recently been completed by Micon Internationaland is evaluating these results. The company continues to review the futuredemand predictions for base metal concentrates particularly zinc ahead of anydecision to move to development and production. In May 2014 Anglesey acquired the rights to earn a 57% interest in theGrangesberg iron ore mine. The Grangesberg iron ore mine is situated in themineral-rich Bergslagen district of central Sweden about 200 kilometresnorth-west of Stockholm. Until its closure in 1989 due to prevailing marketconditions, the Grangesberg mine was the third largest iron ore mine in Sweden,with in excess of 150 million tonnes of iron ore having been mined down toaround 500 metres deep. Anglesey holds 15.3% of the shares of Labrador Iron Mines Holdings Limitedwhich over the three years 2011 to 2013 produced about 3.5 million tonnes ofiron ore from its operations in Canada, all of which was sold in the China spotmarket.
