Course Summary

Summary

The mineral inventory of a mining or exploration company is quantified as resource/reserve estimates with associated error levels that, in many cases, are unknown. Consequently, the estimation procedure should incorporate efforts to minimize errors at every level of decision.

This short course will consider the detailed methodology of various resource/reserve estimation methods that are in common use in the Mining Industry. Emphasis will be on general procedures, inherent assumptions, and advantages and limitations of each of the principal methods. Methods to be discussed include: polygonal estimation, nearest neighbour estimation triangular estimation, contour estimation, method of sections (plans) estimation, inverse distance estimation, and ordinary kriging estimation. All of these estimation methods have significant practical limitations for appropriate use.

For many of the estimation methods, decisions are required that have a bearing on classification of resources/reserves. Consequently, criteria for classification will be discussed from the perspective of the estimation procedure.

All methods require assumptions, either implicit or explicit, that impact significantly on quantity and quality of estimated resources/reserves, for example, block size, search radius, anisotropy, geological continuity, grade continuity, stationarity, etc. The nature of these assumptions will be discussed in detail.

Some of the procedures and concerns will be illustrated with software that will be provided. A laptop computer, while not essential during the course itself, would be useful.

Attendees may want to purchase a copy of the book, “Applied Mineral Inventory Estimation”, (pictured above, right) for further study at leisure. Note that it is not essential for course attendees to have the book while at the course.

Pre-Course e-Learning

Prior to the course, registered delegates have access to the online e-learning material consisting of an introductory course titled Conventional Methods of Resource / Reserve Estimation.

Certificate in Mining Studies

This course qualifies for two days of short course credit for the Certificate in Mining Studies (CMS), a continuing education program of accredited short courses, webcasts and online courses for lifelong learning in mining, supported by University of British Columbia, University of Arizona and University of Concepción. more details »

Continuing Professional Development (CPD)

Registered participants who attend the entire short course and complete an evaluation at the end of the course will receive a Certificate of Attendance, confirming the Professional Development Hours (PDH)/Continuing Education Units (CEU) earned. Please confirm with your employer and/or professional association that this course qualifies for CPD.

Who Should Attend?

The course is aimed at geologists, mining engineers, surveyors, geostatisticians, and any other professionals dealing with the estimation of resources/reserves in a mining context.

Dr. Alastair Sinclair

Alastair J. Sinclair obtained his B.A.Sc. and M.A.Sc. degrees in geological engineering from the University of Toronto (1957 and 1958) and a Ph.D. in Economic Geology from the University of British Columbia (1964). From 1962 to 1964 he taught in the Dept. of Geology, University of Washington, Seattle; and from 1964 to 1998 taught at the University of British Columbia.

In addition to teaching at UBC he was Head of the Department of Geological Sciences (1985-1990) and Director of Geological Engineering (1991-1998). He is presently Professor Emeritus in geological engineering at the University of British Columbia. For many years he taught courses in Economic Geology, Mineral Inventory Estimation and Mineralography and Ore Microscopy. His research activities have focused on Mineral Exploration Data Analysis, Resource Estimation of Mineral Deposits and Quality Control Aspects of Resource Evaluation.

He has presented a wide range of short courses for mining companies and professional organizations and has consulted widely for the international mining industry; he continues to be active in these fields.
