The contract comes after on-site testing and preliminary assessment of SART integration into the metallurgical process at Parral, which was completed earlier by BQE Water.

Under the contract, BQE Water's scope of work will include plant engineering design, process automation, engineering support during procurement and construction, plant commissioning, and ongoing operations support after plant start-up.

The plant construction is expected to be completed by the end of the December 2019 quarter. Once the plant is commissioned, BQE Water will provide operations support services for a monthly fee for a period of three years.

Anis Nehme, COO of GoGold Resources, said: "We have been working with BQE Water for the past few years to evaluate SART integration into the Parral project and we are relying on their expertise to help us maximise the positive contribution SART can bring to the project's overall performance."

David Kratochvil, president and CEO of BQE Water, commented: "This contract is further proof of our leadership in the safe, cost-effective and rapid deployment of SART to help precious metals producers improve the metallurgical and environmental performance of their projects. We stand behind our proven process designs perfected over multiple large projects completed in the past decade and in our operations support capabilities to ensure SART benefits are maximised while operational risks are minimised."

Owned and operated by GoGold Resources, the Parral project involves the reprocessing of old tailings to recover silver and gold by conventional cyanidation. In addition to the precious metals, the tailings also contain significant quantities of cyanide soluble copper and zinc. These base metals compete for cyanide, causing high cyanide consumption and increasing operating costs.
