Confidential Client - Bulgaria

Project Highlights:

  • Due Diligence

Confidential Client – Tierra Group performed a pre-investment Technical Due Diligence Review that included a detailed analysis and risk assessment for a 150-m high co-disposal (tailings and waste rock) storage facility. The facility included two 80-m high waste rock platforms upon which upstream storage cells were constructed using waste rock to retain filtered tailings. The design relied on a free-draining methodology that included an intricate internal drainage system utilizing geocomposite(s), wick and gravel drainage network.
