Pacific Booker Minerals Inc. Responds to the Geomembrane Lined Tailings Storage Facility Plan
Vancouver BC, November 20, 2012: The Company would like to provide some
additional information on the plan to line the Tailings Storage Facility.
An Environmental Assessment is conducted at the conceptual design level prior to
detailed engineering and obtaining the various Licenses and Permits required for
the construction, operation, decommissioning and reclamation of a mine. The
Company’s Environmental Assessment Certificate Application for the proposed
Morrison Copper/Gold mine was based on a Feasibility level design, which was a
comprehensive technical and economic study.
The Company’s Environmental Assessment Certificate contained 32 conditions. They
are conditions that the Company would have to meet prior to obtaining the Mines
Act Permit and conditions that the Company would have to meet during
Construction, Operations and Closure, in order to comply with the Mines Act and
Environmental Management Act.
Condition #9, lining the Tailings Storage Facility with a geomembrane liner was
at the request of the BC Environmental Assessment Office and its reviewers who
requested water quality predictions for the Tailings Storage Facility receiving
streams and emergent groundwater in Morrison Lake lakebed for a geomembrane
lined Tailings Storage Facility. However, the extent of the geomembrane liner
would be determined during detailed engineering and prior to the issuance of the
Mines Act Permit. The geomembrane liner, if required, is proven technology that
has been used at several mines in BC and would be installed over the 21 year
life of the mine.
The BC Environmental Assessment Office’ User Guide states that it is common for
an environmental assessment certificate to have over 100 conditions. Therefore,
the Company’s 32 conditions is a relatively low number of conditions. Two
previously approved mines contained 197 and 96 conditions respectively.
