RPS has been assisting Perseus with various mine water management aspects at the Edikan Gold mine in Ghana since 2012. Our staff work closely with members of both the Perseus site teams (in Ghana) and Perseus Senior Management teams (in Australia). We have worked with members of the Mining, Environment, Sustainability, Geology, Geotechnical, Processing, Engineering & Exploration teams.
Some of the recent work packages completed by RPS include:
Site water management review of extensive mine site; including active open pits and historically mined (now flooded) open pits and a proposed new underground mine.
Assessment of current pit dewatering, future dewatering requirements (both open pit and underground) and dewatering requirements of flooded pits.
Design of river diversion drains around proposed pit expansions.
Training of client’s site staff on groundwater monitoring bore installation and on-going water monitoring.
Hydrological/hydrogeological aspects of Environment Approval Study for a proposed new underground mine; including the prediction of potential impact on local village wells/river and development of a dewatering design for the new underground mine.
Numerical groundwater modelling to assess option for in-pit tailings disposal.
Regular site inspections to support on-going operations.
RPS also provides support to Perseus on three of the their projects in Cote d’Ivoire (Yaoure, Sissingue and Bele) where we provide hydrogeological/hydrological impact on mine water supply, mine dewatering tailings seepage, borehole yield assessment and storm water management.
