PE Mining is a once-a-year NCEES exam with 85 questions, a 9.5-hour appointment, and a current first-time pass rate of 57%. The heaviest areas are mine equipment and systems, mining methods and layouts, plant equipment and systems, and the cluster of mine planning, ground control, and process flow-sheet topics. Strong preparation requires both mining-operations judgment and mineral-processing fundamentals, plus comfort switching between SI and USCS units.
About the PE Mining Exam
The NCEES PE Mining and Mineral Processing exam is an 85-question computer-based test administered once per year for engineers pursuing mining licensure. The current specifications, effective beginning October 2025 and still in use for the October 27, 2026 administration, cover 13 knowledge groups spanning exploration, resource evaluation, mine planning and operations, mineral processing, plant systems, environmental management, and reclamation. The 9.5-hour appointment includes 8.5 hours of exam time plus tutorial and a scheduled break, and the exam includes multiple-choice questions and alternative item types.

PE Mining Exam Content Outline
Exploration: Methods and Techniques
Physical and structural geology, mineralogy, geochemistry, exploration sampling and drilling, and mining-law fundamentals.
Exploration: Site Geologic and Geotechnical Conditions
Hydrology and hydrogeology, sample interpretation, rock-mass evaluation, and geologic or reserve block modeling.
Exploration: Resources and Reserves
Resource and reserve classification, economic geology, and estimation or interpretation of quantity and quality.
Mine Planning and Operations: Mining Methods and Layouts
Surface, underground, and in situ methods plus shafts, slopes, adits, haul roads, and site access planning.
Mine Planning and Operations: Mine Equipment, Facilities, and Systems
Production equipment, haulage, ventilation, power, drilling and blasting, pumping, and monitoring or control systems.
Mine Planning and Operations: Ground Control
Slope stability, strata control, pillar design, shaft stability, geomechanics, rock-mass systems, and strength testing.
Mine Planning and Operations: Mine Planning and Site Layout
Surveying, GPS, GIS, unmanned systems, logistics, maintenance systems, and facility layout decisions.
Mineral Processing: Laboratory and Pilot Testing
Assays, diagnostic leaching, extraction kinetics, Bond work index, coal washability, and linking ore characteristics to process choice.
Mineral Processing: Process Flow Sheets
Scale-up, hydrometallurgy and pyrometallurgy, comminution and beneficiation, solid-liquid separation, and plant balances.
Mineral Processing: Plant Equipment, Facilities, and Systems
Plant layout, P&IDs, equipment selection and sizing, process control, operating requirements, and process sampling.
Environment and Reclamation: Characterization and Baseline

Frequently Asked Questions
How is the PE Mining exam structured in 2026?
NCEES lists the PE Mining and Mineral Processing exam as an 85-question computer-based exam administered once per year. The total appointment is 9.5 hours and includes a short tutorial, 8.5 hours of exam time, and a 50-minute scheduled break. The exam includes both multiple-choice questions and alternative item types, so you should practice more than standard single-answer formats.
What passing score do I need for PE Mining?
NCEES does not publish a fixed passing percentage for the PE Mining exam. Exams are scored on the total number of correct answers and converted to a scaled standard that accounts for minor form-to-form difficulty differences. Your result is reported simply as pass or fail, with a diagnostic report if you do not pass.
How often is the PE Mining exam offered?
The PE Mining and Mineral Processing exam is offered once per year because it has a smaller examinee population than year-round PE disciplines. NCEES currently lists the next test date as October 27, 2026. Because there is only one annual sitting, seat availability and board-approval timing matter more than they do for year-round PE exams.
What changed in the latest PE Mining specifications?
The live blueprint is the version effective beginning October 2025, and that same specification is what NCEES is using for the 2026 administration. The current outline explicitly lists 13 knowledge groups, 85 total questions, alternative item types, and embedded universal considerations such as engineering economics, cost management, laws and regulations, and facility construction. There was no separate mining-specific blueprint revision posted after that October 2025 update as of March 12, 2026.
What references are provided during the PE Mining exam?
NCEES provides an electronic reference handbook and the specified design standards during the exam. Those electronic materials are the only references allowed in the exam room, and personal copies are not permitted. Successful candidates usually spend time learning the handbook structure and searchable-PDF workflow before exam day.
Which topics tend to drive the most points?
The largest official ranges are Plant Equipment, Facilities, and Systems (9-14 questions), Mine Equipment, Facilities, and Systems (8-12), and Mining Methods and Layouts (7-11). Ground Control, Mine Planning and Site Layout, and Process Flow Sheets each contribute another 6-9 questions, so operations-heavy and process-heavy preparation usually matters more than memorizing fringe exploration details. Environmental management and reclamation also remain material because the final three groups can combine for 13-21 questions.
