EGBC National Exam — Mining and Mineral Processing Engineering, 09-MMP-A4 Mine Valuation and Mineral Resource Estimation, undated sitting. 3 hours duration; one handwritten 8.5×11 in reference sheet permitted (not an open-book exam); only approved Sharp or Casio calculators allowed. Question 1 is compulsory (parts 1.1–1.5); candidates then select THREE of the five optional Questions 2–6 (20 marks each) to complete the paper.

Reference texts: Isaaks & Srivastava, An Introduction to Applied Geostatistics (variogram modelling, anisotropy, volume–variance relations); Hustrulid, Kuchta & Martin, Open Pit Mine Planning and Design (mine scheduling, NPV/valuation methods, stripping-ratio economics); Gentry & O'Neil, Mine Investment Analysis (Canadian mining taxation, CCA classes, smelter/refining contract terms, net smelter return); SME Mining Engineering Handbook, 3rd ed. (mineral exploration/evaluation stages, ore reserve classification); Guilbert & Park, The Geology of Ore Deposits (volcanogenic massive sulphide genesis); CIM Best Practice Guidelines and NI 43-101 (Canadian Securities Administrators).

Some question wording is assumed where the paper is unclear. Several tables in the paper do not reconcile arithmetically (the Q1.4.3 reserve table, the Q4 ore/waste schedule totals, the Q5.5 earnings-split percentages), and some sub-part mark values do not add to the question totals. This solution answers the conceptual and methodological content in full and works the self-consistent numeric sub-parts (NPV in 1.3, the nested variogram in 3.2, the depreciation schedule in 5.1, the NSV/NSR chain in 6.3–6.5), flagging every place an inconsistency is carried forward.
