Coordination of underground construction and mine development o Coordination of construction, involving multidisciplinary activities (horizontal and vertical mine development, constructions, electrification network, pumping, etc.) o Mine design on a Deep expansion (levels, ramps, ore handling infrastructures, ore pass, ventilation, electric network, pumping, escape way, maintenance bay, etc)o Mine development planning (3 months to 3 years, underground trucks capacity)o Rail-Veyor technology, mine design on this innovation

Supervision of blasting technical team (6 mining technicians)o Revise, adjust and approve all drill patterns and blast timing o Follow up on drill and shovel wear pieces (drill bit, rod, bucket tooth, lips, etc)

Supervision of medium term planning and mining project team o Lead medium term planning o Lead mining projects (Environmental control strategy; Mine water pumping; Mine electrification network; Mine infrastructure construction, road, stockpile, waste dump, dam, etc…)o Act as subject matter expert in operational excellence projects

Annual mining plan/Business plano Develop and optimize the Annual mine plan (9 pits) and the quarterly reviewo Define the required equipment efficiency of all fleets to meet Business plan production targets (14 drills, 13 shovels and 3 loaders, 56 trucks) o End of month reconciliationRolling 3 months mining plano Identify deviations from Business Plan and recalculate monthly production targets revised on Most Recent Forecast (MRF)o Monthly adjust the 3 months plan depending on advances / delays per sectoro Recalculate the required equipment efficiency of all fleets Others responsibilityo Pits design modificationo Drill blast pattern approval (planning part)o ISO 9001 involvement in internal and external audits

o Dispatch team tasks to ensure survey, drill pattern field indication, inventory estimations, geological sampling and interpretation, geotechnical data gathering, environmental sampling, etc. o Manage the work schedule, holidays, disciplinary records, hiring, etc.o Prepare and animate monthly safety meeting, investigate and analyze accidents, prepare written report.

Weekly mining plano Plan daily production for the next 7 days depending on the MRF objectives; Calculate daily ore blend and waste removal Coordinate maintenance schedule of production equipment Prioritize work zone and bench preparation Include operational constraint and identify potential risk to plan achievement Schedule mine projects works

Ground controlo Inspect pit walls, identify potential instabilities, follow up on corrective actionsMonitoring o Implement monitoring programs, supervise installation of instrumentation, process and interpret data, calibrate alarm level (Slope stability radars, prism, inclinometer, extensometer and piezometre)Wall scaling and water depressurisationo Plan and inspect scaling and diamond drilling work place
