Geologist

About This Role

This role owns the geological knowledge of the Hellyer mine, covering the Fossey underground, the tailings resource, and the surrounding exploration ground, as well as the grade of the ore produced. The geologist will make ore calls, track grade from the face to the ship, and maintain geological data, interpretations, and models that underpin the mine plan and future beneficiation efforts.

Responsibilities

• Work in line with the Work Health and Safety Act 2012 (Tas), the Mines Work Health and Safety (Supplementary Requirements) Act 2012 (Tas), associated regulations, and the site Safety and Health Management System
• Report geological and geotechnical hazards seen at the face (structures, ground conditions, water, voids) to the Shift Supervisor and Underground Manager in the same shift, and record them
• Follow the site lead exposure controls and health monitoring for work with lead bearing ore and samples
• Take part in risk assessments, change management, and incident investigations, and close out assigned actions on time
• Be visible underground: mapping and sampling at the face is the core of the job, alongside planned field leadership interactions
• Map and, where required, sample every development cut, and issue ore and waste mark-ups before the heading is bogged
• Define ore boundaries for stope design with the Mining Engineer, and issue ore calls and bogging instructions during stope production
• Classify waste as it is mined so that it is placed or reused correctly, working with the Environmental Officer on acid forming potential
• Design and supervise grade control drilling and sampling programs, and turn results into updated ore outlines quickly enough to guide the operation
• Track dilution and ore loss for each stope with the Mining Engineer, and act on the causes
• Reconcile grade from the mine to the port each month and act on the variances
• Own the drillhole and sampling database, the sampling quality control program, and the site’s geological records
• Maintain the geological interpretation, wireframes, and grade model for Fossey, and the ore inventory the schedule is built on
• Own the tailings resource model: tonnes, grade, and depletion as the dredge progresses, so the flotation circuit is fed to plan
• Provide the geological and grade inputs (mineralogy, grade variability, sample material) to the studies on beneficiating the ore
• Identify and rank targets above and below ground: extensions to Fossey from underground, and surface targets on the tenements
• Prepare exploration proposals with costs and expected outcomes, then plan and run the approved programs, including drilling, logging, sampling, contractor management, and reporting

Requirements

• Degree in Geology, Earth Science, or an equivalent qualification
