Terra Gold Mining Pty Ltd, a wholly owned subsidiary of GBS Gold Australia Pty Ltd proposes to commence mining activities at the previously worked Maud Creek Mine site near Katherine, Northern Territory. The operation will involve construction of an underground decline, stockpile area, and associated infrastructure. Extracted ores will be transported to Union Reefs Gold Mine for processing (URS 2008). Mine sites have the potential to create or exacerbate mosquito breeding, from the creation of water dams, wetland filters, borrow pits, sediment traps, pit water discharge, waste water disposal, as well as the construction of roads and mine waste dumps. Mine sites also have the potential to introduce new mosquito species into the Northern Territory, such as the dengue mosquito Aedes aegypti from North Queensland, if equipment is sourced from this area. Therefore, all major development in the NT is required to consider mosquito breeding during the Environmental Assessment process, to ensure development does not create new mosquito breeding sites.
