Pacific Booker Minerals Inc. (TSXV:BKM,NYSE:PBM) received a memorandum, prepared by Klohn Crippen Berger Ltd., on geomembrane lined tailings storage facilities. Lining the tailings storage facility with a geomembrane liner was one of the conditions of the Company’s application for an Environmental Assessment Certificate.
As quoted in the press release:
The memorandum provides a summary of geomembrane lined tailings storage facilities and lists a number of projects where liners are used and where liners are incorporated into the design phase. The memorandum suggests (at least) a thousand years as the potential life of a liner that is buried below tailings (maintains a near constant moderate temperature).
