Introduction to Mining Geostatistics: Intuitive Applications with Excel and R is a practical and accessible guide to geostatistical techniques in mineral exploration, with a strong focus on reserves estimation. Designed for students, researchers, and industry professionals, this book blends fundamental concepts of theory with hands-on applications, using Excel and R to simplify complex analyses.

Key topics include:

Essential Statistical Foundations - Master core data analysis techniques for ore reserves estimation.
Sampling Strategies & Error Analysis - Minimize uncertainty and improve data reliability.
Spatial Analysis & Kriging - Use variograms, covariance functions, and Kriging algorithms to estimate unknown values from borehole data.
Multivariate Geostatistics - Model interdependent variables to enhance accuracy and predictive power.
Stochastic Simulation - Explore alternative estimation methods for risk assessment and scenario analysis.
Reserve Classification & Reporting - Understand global classification systems and key reserve estimation parameters.

Filled with real-world case studies and practical examples, this book bridges theory and application, making geostatistics intuitive and approachable. Whether you're optimizing exploration projects, improving resource estimates, or conducting economic risk assessments, this guide equips you with the tools to make informed decisions.

Valakas, George
Dr George Valakas is a senior researcher at the School of Mining and Metallurgical Engineering in National Technical University of Athens, where he earned his Ph.D. specializing in geostatistics and optimization methods. Within this institution, he now serves as a dedicated lecturer and actively engages in various education projects supported by EU's EIT Raw Materials programme. His educational journey began with an undergraduate degree in Statistics from Athens University of Economics and Business, and he further expanded his knowledge by obtaining a M.Sc. degree in Environmental Analysis of Terrestrial Systems from the University of Sheffield in the UK. His primary areas of expertise encompass geostatistics, optimization methods, mineral exploration, and the innovative development of interactive educational tools that adeptly integrate complex concepts and theories within the overarching framework of sustainable development principles. He is the recipient of a prestigious postdoctoral fellowship, awarded by the State Scholarships Foundation of Greece. The primary objective of this fellowship was to develop an R package for applying Plurigaussian simulation and co-simulation between facies and continuous variables, further demonstrating his commitment to advancing this field.
