Brian C. Traweek, P.E. – Associate Mining Engineer


Brian Traweek has mining engineering experience in industrial minerals, coal, and copper. He has completed mine plans for every stage of mining, from initial financial feasibility, to permitting, to mine operations planning, to reclamation and final post-mining land use. His mine planning experience has ranged from weekly production shift operations planning and individual blast pattern design, to life-of-mine plans. Brian’s previous experience in an operations environment provides him with a field practicality perspective in his problem solving approach.  Beyond mine planning, Brian has specific extensive experience in erosion & sedimentation control design and permitting, and in water treatment.
