254 square km or ~34.2% of the originally granted area of a licence centred ~30 km east-northeast of the Prominent Hill mine has been relinquished due to its now perceived low prospectivity for buried basement-hosted IOCG mineralisation. During the 2012-2014 reporting period, Fortescue conducted an initial desktop review of the tenement area's prospectivity, based on available previous company data. This review included reviews done by senior Fortescue geologists as well as by external consultants. Across the tenement area in 2014, historic regional ground gravity survey data coverage was augmented via spot gravity readings taken by the company to achieve an average 1 km station spacing. In September 2017, across multiple Fortescue exploration tenements, contractor Atlas Geophysics conducted a regional gravity survey having a 500 m nominal station spacing which was designed to provide complete ground gravity coverage and to infill previous 1 km spaced gravity data. 1276 new gravity stations were read on the subject surrendered portion of EL 5023/6057. The relevant survey data subset is released herein. During 2018, an on-ground reconnaissance trip was conducted by Fortescue geologists to gauge the extent of access via existing gazetted roads onto various project tenements including EL 6057. No other work was done on the relinquished ground before or after the decision was made in 2020 to drop it.
