Feasibility Study and Technical Report - Pretivm

Air FreightScheduled and chartered cargo service is available to nearby communities such asTerrace, Smithers, and Dease Lake. Cargo could also be delivered to the Bowser Creekair strip.OVERSIZE AND HEAVY EQUIPMENTFor truck shipments within BC, the legal gross vehicle weight (GVW) limit is 63,500 kg(cargo and transport vehicle combined). Dimension limits of the combination of cargoand transport vehicle are 26 m length by 4.14 m height by 2.6 m width. Any shipmentsthat exceed these dimensions or weight are classified as “overloads” and requireapplications to the Province of BC to obtain permits for travel.TRANSPORT LIMITATIONSIn addition to any transport permits required, bridges along Highway 37 from Kitwanga tothe junction of the Brucejack Access Road will need to be evaluated to ensure that thestructures are capable of handling the legal vehicle weight and dimension requirements.One bridge in particular that may be a limiting factor is the Nass River Bridge. This bridgeis located approximately 141 km north of Kitwanga. It is a single-lane bridge with yieldsigns at either end. Built in 1972, it was constructed with wooden glue-laminated beamsand has a capacity of 90 tons (or 180,000 lb) GVW. The bridge is 323 ft in length andhas a horizontal restriction of 14 ft, 10 in.In an effort to bypass the Nass River Bridge, barging cargo to the Port of Stewart is aviable option. Cargo would travel via barge to Stewart, unloaded, and transferred to truckfor delivery to site along Highway 37A to Meziadin Junction, then north on Highway 37 tothe Knipple Transfer Station. Permits and bridge evaluations may also be required forthe truck haul portion of the trip.The Port of Stewart has the capability of handling equipment via barge on a roll-on/roll-offbasis. Currently, barge unloading takes place at SBT in the north eastern area of theterminal where the ground is sloped from the road level to the waters edge. Inboundmovements would require mobile equipment such as a Bulldozer to assist in pulling theequipment.Cargo that has been either received or loaded on barges includes:pipespaving equipmentcamp trailersgravelbags of concentrate.Pretium Resources Inc. 19-3 1291990200-REP-R0012-02Feasibility Study and Technical Report on the BrucejackProject, Stewart, BC
