Work history

Operation Mining Geologist

Maaden Phosphate Company
Arar, Northern Borders Region
11.2024 - Current
  • Supervised open-pit mining operations and coordinated structured handovers with pit supervisors and sizing plant teams.
  • Applied ore extraction methods (drill, blast, load, haul) with focus on safety and minimizing dilution.
  • Implemented ore grade control and QA/QC protocols, ensuring accurate separation of sub–cut-off material and reliable sampling.
  • Prepared and updated geological grade maps to support mine planning, feed blending, and evaluation.
  • Managed stockpiles and crusher feed optimization to maintain consistent plant performance.
  • Contributed to OBM closing, production reporting, and reconciliation of mine output with business targets.
  • Used Minex and MS Excel for cross-sections, grade control, and data validation.
  • Worked with teams to review and update SOPs for mining and sizing plant operations under MSHEM standards.

Student trainee

Eurasian Resources Group (ERG)
Riyadh, Saudi Arabia
07.2023 - 08.2023
  • Conducted chromite exploration in a serpentinite zone: identified chromite lenses, logged and sampled trenches, produced geological cross-sections, and compiled a geological map of the mineralised zone.
  • Contributed to a porphyry Cu–Au–Ag prospect: mapped lithologies and alteration zones (potassic, propylitic), and documented intrusive phases (granodiorite, porphyry granite with copper oxides).
  • Applied remote sensing and geological mapping to evaluate lithological and structural controls on mineralisation in a regional context.
  • Carried out systematic geological sampling (trenches, gossans, alteration halos) following QA/QC field protocols.
  • Prepared geological reports and maps integrating field, structural, and geochemical data for ore deposit assessment.
  • Gained hands-on experience in:
    Ore deposit exploration (chromite lenses, porphyry copper–gold systems)
    Field mapping & cross-section design
    Geological criteria for economic mineralisation
    Technical reporting & teamwork     in a professional mining environment
