We were engaged to conduct various Surface Water Assessments for MinRes’ lithium mines at Mount Marion and Wodgina.

To facilitate the assessment of surface water impacts from proposed expansions at the mines, our hydrology team reviewed previous investigations, defined catchments, completed flood modelling scenarios of existing and post-development scenarios, identified potential risks to environmental receptors and project operations, and provided recommendations for mitigation of impacts, ongoing monitoring and wet season readiness.

Our latest completed surface water assessment considered the most currently proposed mine plan for the Mount Marion site. Of particular interest was the definition of mitigation options required to prevent inundation of an underground exploration portal within a proposed boxcut, involving consideration of a range of design flood events, bunding heights and potential pumping options for this new artificial catchment area.

About the sites

MinRes is planning the expansion of its Mount Marion lithium operations within the Goldfields region of WA – located 40 km southwest and 50km southeast of Kalgoorlie respectively – along with its Wodgina lithium operation in the Pilbara region of WA, situated 90km south of Port Hedland.
