Perilya operates two underground lead/zinc/silver mines in Broken Hill (NSW Australia). Southern Operations is a remnant operation targeting 1.5Mt per annum of ore. Potosi Operation is a brownfield operation targeting 0.4Mt per annum of ore.
In the period from 2008 to 2012, AMC Consultants annually reviewed the estimation of the Mineral Resource and Ore Reserve for Perilya’s Broken Hill Operations.
AMC’s scope was to provide an independent technical review of the Mineral Resource an Ore Reserve in terms of data quality, process, methodology and with a view to identifying any significant concerns or risks. To meet the scope, AMC engaged with site personnel during the estimation process to ensure that there would be no unresolved issues at the time of public reporting and that the estimates would be reportable in accordance with the JORC Code. Issues identified during the reviews were addressed during the process and recommendations for improvements were implemented in subsequent years.
AMC provided constructive input to the estimation process and assisted site personnel in their roles as competent persons.
AMC’s role was acknowledged in the public reporting of Perilya’s Mineral Resource and Ore Reserve. Perilya found AMC to be professional, competent, and thorough in the provision of this service.
