Gold Canyon Resources Inc. Springpole Gold Access Corridor Project Final Environmental Study Report (1996). The bridges would be installed according to the DFO Operational Statement for Clear Span Bridges, the issued MNR permit(s) and any additional conditions required by MNR. o Birch River and Dead Dog Creeks are major crossings and will be designed as clear span structures (~35 m for Birch River bridge; ~12 m for Dead Dog Creek bridge, to be confirmed in applications that will follow the EA process), with site specific engineering drawings that comply with MNR and DFO standards. The bridges will be constructed in winter along with all of the other construction phase work. Bedrock that is excavated to construct the bridge abutments will be used as rip rap and to surface the approaches for water crossings. This material may be crushed if required. Blasting activities will be in accordance with Wright and Hopky (1998) and the portable crushing contractor will conduct work in accordance with provisions of the Environmental Protection Act. Utilize a rock truck (with a heated box) to import aggregate and use the excavator to place it over the installed culverts. Aggregate would be removed from the nearby FAPs for construction as needed for use on the FMP approved road (refer to Definition of Terms) only. Aggregate that is required for the road beyond the FMP approved road will be sourced from either existing excavations on GCU’s patents or from an existing aggregate pit that is licensed in accordance with the Aggregate Resources Act. The governing policy is provided at the following link: http://www.mnr.gov.on.ca/stdprodconsume/groups/lr/@mnr/@forests/documents/docume nt/275588.pdf One of the reasons GCU has included engineered square timber bridges as an option is because they require very little aggregate when installed. Aggregate that is used for rip rap or erosion protection will be screened to remove fines and ensure that it is cobble size material. Concurrent with the timber harvesting and road construction from the end of the Wenasaga Road, GCU would commence timber harvesting and road construction from GCU’s camp using heavy equipment that is currently in place at the camp. Utilize rig mats / swamp mats or an ice bridge to cross the Birch River with heavy equipment at the bridge location to begin the bridge installation. The DFO Operational Statement for clear span bridges would be followed. Alternatively, GCU would access the east abutment using the equipment that commences work at GCU’s camp. Approximately January 5 to March 15 Finish constructing the Birch River bridge in accordance with the engineering design drawings, DFO’s Clear Span Bridge Operational Statement and any additional conditions required by MNR. There would be no structures below the normal high water mark. Although the crossing is not regarded as navigable except during unusually high water conditions, the bridge would be high enough to allow passage of boats beneath it and in accordance with requirements from Transport Canada. Place black muck (sourced from within road corridor) on the embankments of the placed road fill near the bridges and spread a seed mix with no invasive species before covering the surface with straw mulch, all in accordance with proven best management practice on July 2013 Page 46
Gold Canyon Resources Inc. Springpole Gold Access Corridor Project Final Environmental Study Report forestry roads. The objective is to establish vegetation for erosion control and to minimize impacts to the local aesthetics, so this proven erosion control technique is preferred over the more costly placement of rip rap on fill embankments. Rip rap will still have to be used on and around cribbing to prevent scouring. As a construction objective that is still being evaluated, the height of the fill at the crossing will be minimized in order to minimize aggregate costs, to minimize impacts on the local viewscape and to facilitate the eventual rehabilitation of the road. Approximately March 15 to May 1 Install a modern, monitored gate at the end of the existing FMP road, pending issuance of a Land Use Permit to GCU (refer to location in Figure 2-1). The gate is intended to mitigate the concern over increased access to the area. GCU wishes to prevent any more access to the region than what is already approved in the FMPs. Once the FMP Approved Road is extended by the SFL holder in accordance with the 2014-2019 FMP, the gate would be relocated to the end of the extended FMP Approved Road (refer to location in Figure 2-1). De-mobilize road building contractor. Gravel placement over this winter operational road and upgrading it to an all-weather access road is not part of the currently proposed Project. Pending continued positive exploration results and ongoing consultation, the gravel placement that would be required to upgrade this winter operational road to an all-weather access road may be proposed at a later date. The proposal outlines that Crown dues will be paid based on FRI volumes generated from the SFL holder’s wood supply modelling. GCU has no choice but to use this method: 1. The SFL holder has confirmed they do not want this wood volume. 2. The Resolute Mill in Fort Frances has been on shutdown from the fall of 2012 to July 2013 and has only scheduled a temporary start-up of paper production in 2013 creating a surplus of wood in this part of northwestern Ontario. 3. Based on FRI, 59% of the wood is burnt wood from recent fires. There is no market for logs for use in pulp, paper or sawlogs for wood that has been burnt 18 months ago. The combination of charred wood, insect and fungal damage has destroyed these logs for use in forest products. If the Project is approved, GCU would discontinue the seasonal ice road over Birch Lake, which will reduce access to Birch Lake. Engineering details, construction methods, sediment control plans and contingency plans are provided in Appendix 7. These details are typically reserved for Work Permit applications, but have been included herein for completeness. July 2013 Page 47
