RE:RE:RE:RE:What good is a tailings design with no ore.Get over the tailings facility angle. It is just one of many costly and liability aspects of the project.
The bulk tailings facility will require a liner thus rendering the current engineered tailings facility design obsolete.
A lined facility with pump-back wells is the safest redundancy to assist in ensuring contaiminated groundwater does not recharge surface water impacting aquatic life.
Contaminated/regulated stormater will also require capture, treatment and discharge.
