    Quality Control and Quality Assurance Methods in Geochemical Exploration & Resource Assessment

    Description: This short workshop presents both the theory behind geochemical data quality assessment methods for mineral exploration sampling and resource definition, and a clear and practical approach to the design, implementation, and assessment of such methods. Topics covered range from initial sampling, digestion, and analysis methods and how they impact QA/QC, through data quality assessment concepts, qualitative and quantitative data, types of errors, accuracy and precision assessment methods, to best practices, component errors, and strategies to reduce errors. Included are several practical exercises allowing participants to develop confidence in plotting and assessing quality control data using real-world data. Emphasis will be placed on the use of quality control data to reduce ambiguities that impede the interpretation of mineral exploration results, and to minimize uncertainties in resource estimation.

    This workshop is designed for those new to managing QA/QC programs, as well as those involved in implementing programs but who have not been utilizing the QA/QC results to improve sampling/analysis outcomes. It is normally directed toward an economic geology-oriented audience with interests in mineral exploration and mining. After taking the workshop, the audience can be expected to have the background and insight necessary to design and undertake an appropriate QA/QC regimen that will be acceptable for public disclosure by a company listed on one of the major mining-oriented stock exchanges. Attendees should bring a laptop computer loaded with an Excel® spreadsheet application (or equivalent) to allow them to undertake the practical exercises using spreadsheet templates provided to participants as part of the course.

    Program: This workshop is presented in a one-day format from 9:00 to 5:00, with a one-hour lunch break. Lectures are broken up by 20-minute coffee breaks in the morning and afternoon, and each are followed by computer exercises that allow participants to practice what they have learned. Consequently, participants are encouraged to bring a lap-top computer with spreadsheet program loaded with them to the workshop so they can participate in the exercises.
