• Design and oversee underground core drilling programs. • Work with Mine Planning department and production to produce short and long-term plans.• Work with Tech Services to prepare stopes for economical and safe pillar extraction.• Provide technical assistance in achieving the mine head grade required by the monthly and long- term plans.

• Mine rescue team. Provide ventilation control information to field team to ensure their safety during mine rescue operations. On tech team as a competent person with the use of multi-gas detectors. Certified in advanced fire brigade training.• Help mining operations with their compliance goals by conducting underground mine visits and providing technical assistance on how to economically and safely mine their ore bodies.• Direct and lead weekly, monthly, and end of month meetings with mine production, geology, technical services, superintendents and department managers, to develop and implement solutions for pressing issues, plan for short term and long term goals, and discuss safety topics.• Analyze ore reserves with AutoCAD and Promine programs to determine their economic and mining feasibility. Provide development plans for mining and capital development crews.• Produce project area maps for the technical services department in order to determine prospective pillar retrieval areas and to help production meet their ore metal goals. • Assist to produce LOM plans for the mining operations to assure that mining and pillar extraction is maximized to fullest potential.

• Help ensure that the mining operations were compliant with all applicable environmental regulations.• Conduct internal auditing to help the mines maintain a clean and safe working environment.• Updated all SWPPP and SPCC plans of each mine to be in compliance with EPA regulations.• Data management for regulatory and operational reporting.

•Member of the mine rescue team.•Provide technical assistance to Mine Superintendent, Mine General Foreman, and Mining Engineers regarding short and long-term planning and mining activities.•Produce daily grade report for operation crews and management with daily head grade, stope mining instructions, and safety information.•Produce month end and quarterly reports showing resource additions and depletions, exploration results, and mine/mill grade and tonnage correlations. •Provide geologic support to the Rock Mechanics Engineer in implementing a ground control policy to prevent injury to crews.•Helped to create standardized reports and forms and with their implementation within all of the mines. These forms helped to improve tracking of dilution, ore grade, and provide technical directions and suggestions for operations.•Set a daily example of safety by following company safety protocols.•Use of MineSight, Acquire, and AutoCAD software to: plan percussion and reverse circulation drilling programs to discover new ore bodies and prolong life of existing ore bodies; log drill samples and QA/QC samples; down-hole surveying; mapping of geology and ore grade of mining stopes; and data validation.•Supervise and support geology technicians with panning of drill samples, drill program preparations, and adherence to SOPs.•Supervise explorations drillers during drilling campaigns to assure QA/QC and safety protocols are being followed. •Train new geologists in face grading, mine safety, and dilution tracking.•Work daily with operations to provide technical assistance in achieving the mine head grade required by the 12-week and short-term production plans.•Core logging, preparation for assaying, and specific gravity tests of down-hole drill samples.

• Achieved client production goals on time, safely, and with minimal supervision.• Use of ArcGIS software to collect GPS coordinates and overhead electric line data for the Google Fiber Project• Trained in use of TruPulse 360 R laser rangefinder and Hastings measuring stick to accurately measure and collect field data.
