dc.description.abstract | Groote Eylandt is Aboriginal-owned land, as granted under the Aboriginal Land Rights (NT) Act 1976 (ALRA). The Groote Eylandt Mining Company Pty Ltd (GEMCO) has its obligations defined in various lease documents including Mineral Leases, Exploration Licences in Retention (ELRs) and Special Purpose Leases (SPLs), a Letter of Understanding dated 13 May 1965 and an Agreement dated 16 September 2006. Groote Eylandt is predominantly composed of a stable basement of Proterozoic quartz sandstones and quartzites. The overlying manganese deposits are part of a blanket of Cretaceous sediments lapping onto the western margin of the Proterozoic basement sandstones and quartzites of the McArthur Basin. The manganese orebody is a sedimentary layer, consisting of manganese strata occurring between clay and sand beds and gently undulates beneath the western plains of the island. It extends over an area of about 50 square kilometres as an almost continuous horizon ranging in thickness up to 11 metres. The ore body is thus essentially stratabound and strataform in character. This report covers what is commonly referred to as the 'Eastern Leases', the two Exploration Licences in Retention (ELR 28161 and 28162) that are located east of the main mining leases. Granted in November 2010, these licences cover the areas previously held by GEMCO under Exploration Licence EL10115 and 10108 respectively. No drilling was conducted during the reporting period, however, work associated with the i) Pre-Feasibility Study and ii) Environmental Impact Statement and Supplement Report was completed with environmental approvals well progressed. Baseline environmental monitoring of groundwater and surface water sites continued, and is planned to be carried forward in future years. | |
