TSF design and construction
Junior to mid-level gold producer in WA
The project is an operational mine site located in WA. The site comprises two tailings storage facilities, several satellite pits and an underground mining project.
Our involvement with the project extends back over mid-2017, at which point we were asked to provide guidance with regards to the construction of a tailings storage facility (TSF) designed and partly constructed by others. The initial design was fundamentally flawed and as a result, the client was struggling to meet compliance across the site.
“We intend to transition away from the traditional TSF to a co-deposition dry stacking system and IWL, in turn saving the client upwards of $2M per year on construction alone.“
We have since completed construction of the TSF (starter stage), designed the future stages of the facility, commenced construction of Stage 1, taken over operational control of the facility following poor management and continued to push the client to better understand their whole of site water balance and mine waste management.
We have also since moved to be involved with the design of open pits, site-wide hydrogeological assessments, site-wide water balance and water management plus a fine grind reprocessing project, which in turn has allowed us to oversee the proposed TSF reprocessing and future dry stacking and Integrated Waste Landform design and construction.
Our current involvement with the client sees us with a permanent presence on site to oversee the construction of the current TSF works, deposition of tails into the current operational cell, the plant site upgrade as part of the fine grind reprocessing project and numerous smaller projects (drilling, water recovery, etc.)
Our aim over the coming 12 months is to drastically increase efficiency across the site and bring the operational teams up to date with telemetry systems installed across the site (by MHA following the transition to REC) to better understand the site-wide water balance and use of raw water. We also intend to transition away from the traditional TSF to a co-deposition dry stacking system and IWL, in turn saving the client upwards of $2M per year on construction alone. The fine grind reprocessing will in turn generate a capital return that exceeds the operational cost of the system and waste management.
