Probability graphs display a data set as a cumulative distribution. The most significant use of probability graphs applied to mineral exploration data is in the recognition of the number of populations in a data set, and the partial or complete partitioning of individual values into their respective groups or populations. The significance of the resulting groupings or populations of data must be interpreted. Interpreting probability graphs is largely a matter of understanding the implications of the patterns that result when data sets are plotted. These implications are not always fully appreciated, and in some cases, the conclusions drawn from the probability graphs are incorrect. In this course, you will learn how probability graphs can supplement analyses done using histograms, and how this can be beneficial when interpreting mineral exploration data. The course explains data distributions and populations. You will learn that probability graphs are an easy way to estimate the forms of distributions and their parameters. They are a useful tool to present and analyze many types of numeric data that are the product of mineral exploration programs. The course also highlights general advantages, but also limitations of using probability graphs, and provides useful procedure tips to draw up the graphs. Note that this course assumes a working knowledge of simple statistical concepts (e.g. arithmetic mean, variance, standard deviation, normal density distribution, etc.). The course content uses a clear-cut, idealized approach illustrated by real life practical examples used throughout the mining industry. The Appendix includes a variety of interpretations of published probability graphs with alternate interpretations and discussion on the analytical approaches used by the original publications.

A tenet of investment is that if the risks of an investment are high, then the investor should be compensated for assuming the risks by a high potential return from the investment. However, quite often the risks associated with an investment are not known or understood. The results vary but may include an investment evaluation that is not representative, a bad investment decision, and low returns or even losses. Inadequate technical or financial information is the main reason risks are not taken into account or are misunderstood. Unfortunately, lack of such information is a common situation in mining and other large industrial projects. No amount of investment evaluation or analysis can compensate for lack of information. If the risks are known and can be characterized in some way, methods of investment analysis can be used to provide a quantitative assessment of the risks. One goal of this course is to describe methods for risk quantification, their advantages and limitations, and to give realistic (if not real) examples of their application. Fortunately these methods are simple so that complete evaluation of an investment is (or at least should be) a simple process.

Summary Do you have the most up-to-date information in drilling and blasting to tackle common problems such as drill fleet optimization, explosive selection, and mine-to-mill optimization? Blasting has completely changed in the last five years, yet alone the last twenty to fifty years and there is relatively little information widely published. Today we understand shock breakage, velocity matching, and powder factor are outdated and should never be used in the blasting process. New methods have taken the place of these concepts that allow blasters and engineers to make significant improvements to the drilling and blasting process. This course will cover the new updates in the basics of drilling and blasting which you will use on a daily basis in your career of blast engineering. This course will cover critical topics such as an introduction to modern blasting, how rock actually breaks from explosives, the commercial explosives and initiation systems used today, and the drilling technology available in the industry. The course is divided into short video modules with questions following each lesson to reinforce key concepts.

If you are an exploration geologist, a mining engineer, a metallurgist, a mine accountant, or a practitioner of any of a number of other mining-related specialties, at some time you will be asked to do a cost estimate. Mining is an economic endeavor, and, after safety, the cost of mining and its related processes is one of the most important considerations in that endeavor. This course introduces you to the methodologies of mining cost estimating, and prepares you to complete a credible estimate. The course focuses on itemized cost estimating methods in the context of a mine plan. It covers the costs of excavating, loading, hauling, drilling and auxiliary equipment as well as the costs of supply, personnel, stripping and other requirements. This is a premium course which has been peer-reviewed by a committee appointed by the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) and the Society for Mining, Metallurgy and Exploration (SME).

The investment necessary to start a mine is of the order of 10's to 100's of millions of dollars. In order for the investment to be profitable, the potential product in the ground must be present in adequate quantities and quality to justify a decision to invest. Mining and processing systems used to extract the products must then operate so as to produce revenue to offset the planned investment and to provide an acceptable profit. Clearly, all technological and financial decisions regarding planned production are built on an understanding of the mineral assets available. Thus, the estimation of grade and location of material in the ground (in situ resources) must be known with an acceptable degree of confidence. This is especially true of certain large, low grade deposits for which grade is only slightly above minimum profitable levels, and for some precious metal deposits where only a small percentage of mineralized ground can be mined at a profit. Mining profits are strongly leveraged to product price and to realized grade of material mined. A small difference between planned (estimated) and realized production grade, or a small change in metal price, can have a large impact on mine profitability. The three undertakings, ore estimation, mine planning and grade control, are complementary in an efficient mining operation and are natural progressions one to another. The integration of these three endeavors is important because the grade control system must balance with the ore reserve as well as with the final products of the operating plant, and both estimation and grade control are influenced by planned operational procedures. If this balance is not achieved then the original investment may be in jeopardy. Reappraisals of mineral inventories can be necessary many times both prior to and during the life of a mine. Resource/reserve estimation procedures commonly are considered in two categories, empirical and geostatistical. This course is confined to the principal empirical methods of estimation.
