Distinguished Drafting Engineer

Skills at this level

Pit Optimization

— Runs and interprets open-pit optimization to define ultimate pit shells and phased pushbacks from block models, balancing strip ratio, cut-off grade and revenue against mining cost to maximize project value.

Ore Blending

— Plans the sequence and proportions in which ore of varying grades and characteristics is mined and combined to meet mill feed specifications and consistent product quality targets over the schedule.

Mine Scheduling

— Develops development and operations schedules that translate the long-range mine plan into achievable short-range production sequences, ensuring bench/level advance, equipment and grade targets are met.

Mine Technical Reporting

— Writes and compiles pre-feasibility and feasibility mine technical reports, documenting resource inputs, design assumptions, schedules and conclusions to a standard that supports investment and client decision-making.

Mine Economic Analysis

— Evaluates the economics of mine designs and sequencing — capital and operating cost, cut-off grade, NPV and cash-flow trade-offs — to justify plan selection and support decision-making.

Mine Planning Systems & Standards

— Develops and implements mine planning, engineering and related systems and standards, ensuring short-range plans align with and achieve long-range and business objectives.

Mine Modeling & Optimization Software

— Builds block models and runs optimization and scheduling scenarios in Whittle, Vulcan and Deswik to test design alternatives; proficiency deepens with seniority and larger, riskier ore bodies.

Mine Layout Drafting

— Produces and revises mine layouts, cross-sections and infrastructure drawings in AutoCAD to design standards, translating engineering intent into buildable, dimensioned representations.

Geological Data Analysis

— Interprets drillhole, assay and survey data to characterize the ore body and inform grade estimation, design boundaries and mining constraints.

Mine Safety & Environmental Compliance

— Checks that mine designs and active workings conform to safety and environmental regulations, identifying and mitigating hazards such as slope instability and ground-control risk.

Geotechnical & Ground-Control Judgment

— Predicts slope stability, ground behavior and factors of safety through calculation to ensure life-critical mine structures are designed right before construction, treating field tests as the ultimate authority under doubt.

Mine Failure Analysis

— Conducts forensic investigation of mine failures and chronic underperformance — slope failures, dilution, schedule collapse — to isolate the root cause behind the apparent cause and prevent recurrence across the operation.

Client Technical Advisory

— Advises mining clients and their management on mine strategy, design conclusions and project terms, presenting and defending technical findings in feasibility and stakeholder reviews.

Technical Mentorship & Standards Leadership

— Sets technical standards, reviews others' plans and designs, and develops junior and senior engineers' capability in mine planning, ventilation or production-optimization specializations.
