Kemess Underground Project Public Comment Period
AuRico Metals Inc., 1076 Main Street, Suite 2, Smithers, BC, V0J 2N0 is proposing to develop the Kemess Underground Project (the Project) located approximately 300 km northwest of Mackenzie, British Columbia. The Project is an underground gold-copper mine which is designed to process an average of approximately 25,000 tonnes per day of ore over a 13-year Operations phase. An Environmental Assessment Certificate (EAC #M17-01) was issued for the Project on March 15, 2017.
The land upon which the Kemess Underground Project is situated and the discharge occurs is provincial Crown land (legal description: Mining Lease 354991; District Lots 7198, 7199, 7201, 7204, 7207), located in the Cassiar District, Omineca Mining Division.
The Major Mines Permitting Office (MMPO) is leading a joint application review for the proposed Kemess Underground Project on behalf of the BC Ministry of Energy, Mines and Petroleum Resources, BC Ministry of Environment and Climate Change Strategy, and BC Ministry of Forests, Lands, Natural Resource Operations & Rural Development. The MMPO is currently inviting public comments about the proposed Kemess Underground Project related to the following authorizations:
Mines Act Permit Amendment
AuRico Metals Inc. has submitted, as part of a joint application, a proposed mine plan to amend Permit M-206 for the Kemess Underground Project. The Permit was issued on July 12, 1996, and last amended July 3, 2015 (approving of a name change).
Environmental Management Act Permit Amendments
AuRico Metals Inc. has submitted an amendment application to the Director to amend Permit 15335, issued December 8, 1998 and last amended April 5, 2017 which authorizes the discharge of effluent from the Kemess South Mine and Permit 14928, issued July 29, 1997 and last amended December 20, 2011 which authorizes the discharge of air contaminants and refuse to ground/active waste rock dump from a 225 person gold-copper mine complex camp.
The proposed amendment requests the addition of the following treated effluent discharges:
- Surface runoff collected by the Kemess Lake Valley (KLV) sediment pond with final discharge to El Condor Creek - Roadside surface runoff collection ditch along the Kemess Underground (KUG) access road south of the access tunnel with discharge to ground (at station 2+229) - KUG Tailings Storage Facility (TSF) Dewatering and Discharge into Attichika Creek (Construction to Year 1 Operations) - KUG TSF Dewatering and Discharge into Attichika Creek (Operations Phase, Years 2-13) - Sewage treatment plant discharge to the Mill Sedimentation Pond in the KUG Mine Site area
The discharge rate and characteristics of effluent emissions from listed sources are described below:
1) The maximum discharge rate to El Condor Creek will be 37,100 m3/day with the effluent characteristics as follows:
2) The maximum discharge rate from surface runoff collection ditch along the KUG access road will be 83,808 m3/day with the effluent characteristics as follows:
3) The maximum discharge rate KUG TSF to Attichika Creek (Construction to Year 1 Operations) will be 1,260 L/s with the effluent characteristics as follows:
4) The maximum discharge rate KUG TSF to Attichika Creek (Operations Phase, Years 2-13) will be 170 L/s with the effluent characteristics as follows:
5) The maximum discharge rate from the sewage treatment plant to the Mill Sedimentation Pond will be 59 m3/day with the effluent characteristics as follows:
The amendment application requests authorisation for the air discharges for the following sources:
- a refuse incinerator; - the Kemess Underground Tailings Storage Facility (KUG TSF) beach; and - a ventilation exhaust raise.
The discharge rate and characteristics of air emissions from listed sources are described below:
1) The existing refuse incinerator will be replaced with a new Eco Waste Solutions (EWS) ECO 1TN1P incinerator, which will
have a maximum discharge rate of 2.52 m3/s and emission characteristics as follows:
2) The KUG TSF beach that will be created during the Operations phase will have a maximum discharge rate of 0.59 g/s and emission characteristics as follows:
3) The KUG ventilation exhaust above the underground workings will have a maximum discharge rate of 400 m3/s and emission characteristics as follows:
A copy of the joint permit application, including supporting documentation, is available for public viewing at the Smithers Public Library (3817 Alfred Ave., Smithers, BC), Mackenzie Public Library (400 Skeena Dr., Mackenzie, BC), and Prince George Public Library (Bob Harkins Branch, 888 Canada Games Way, Prince George, BC).
Any person interested in, or who may be adversely affected by, the proposed Project and wishes to provide relevant information may, within 30 days, send written comments to Harold Bent, Director, Environment, AuRico Metals Inc. 1076 Main Street, Suite 2, Smithers, BC V0J 2N0, with a copy to Todd Goodsell, Senior Project Lead, Major Mine Permitting Office, B.C.
