SRE Survey EXECUTIVE SUMMARY Brockman Resources Limited has submitted a Miscellaneous Licence (L 45/225) application under the Mining Act 1978 for a railway corridor to connect the Marillana mining lease (M47/1414) to the existing FMG railway infrastructure. Brockman commissioned ecologia Environment to undertake a comprehensive biological survey of the short range endemic (SRE) invertebrate
