Kimberley Metals Pty Ltd engaged AGE to assist with a pre-feasibility study to develop the Sorby Hills lead, silver, zinc deposit in the East Kimberley region of Western Australia. The deposit was first investigated in the late 1970’s and early 1980’s when a decline encountered large groundwater inflows. AGE were engaged to design an investigation program to gain an understanding of pit dewatering issues and options. Fieldwork undertaken by AGE included test pumping trials and to determine dewatering requirements for the proposed mine development. The work was also used to support the submission to the Department of Water – Western Australia as part of the project approvals process.
