Geochemistry is a hard field to break into and even harder when mentors are hard to find. An initiative at LKI Consulting is to help young geochemists and those with an interest in the field to navigate geochemical principles and master the basics. 

This page is in memoriam of one of our mentors and is further dedicated to mentors everywhere.

Digests for Exploration Geochemistry

Lab schedules are informative for pricing and services, but it can be difficult to understand the differences between digests and which to choose.

Metal Mobility and Ligands

Using a high sulfidation epithermal system as an example, here we are looking at the fundamentals of how metals get from point A to point B in a hydrothermal system, exploring Pearson’s Rules and some basic concepts of the aqueous geochemistry of gold.

Metal Mobility and Ligands II

Building on the concepts presented in “Metal Mobility & Ligands,” we look at how gold travels in different ore deposit systems and under different physicochemical conditions.

Key QA/QC Terminology

QA/QC programs are littered with terminology that veteran geos take for granted. Let’s clarify the terms and get you on your way to building your program.

Mapping porphyry alteration more precisely: a hyperspectral imaging and geochemistry case study from the Caspiche Porphyry, Chile

A tour through the mineralogy and reaction fronts of the Caspiche Porphyry (Chile) with a focus on why it is important to reject dogma and bag terms with the technologies that we have available to us in the mining industry. As presented at the IAGS 2022 conference in Viña del Mar, Chile.

Geochemistry & Hyperspectral: Better Together

An introduction to both hyperspectral core imaging (HSI) and geochemistry basics. This talk concludes with a module of how these two disciplines are not one or the other, but work better when used together. This talk was presented for geohug, a global initiative to connect, laugh, share ideas, information and knowledge with the wider geoscience community.

Hyperspectral Core Imaging Applications in Skarn Deposits

Introduction to hyperspectral imaging technology with a focus on how this technology has been applied to skarn deposits in exploration and mining. This talk with given to the SEG student chapter at The Colorado School of Mines (USA).

Mapping porphyry alteration more precisely: a hyperspectral imaging and geochemistry case study from the Caspiche Porphyry, Chile

This talk given at Explore2020 is meant to empower Corescan clients to use their data in novel ways, as well as to continue to bring geoscientists towards integrating hyperspectral imaging technology into their projects, whether they are complex skarns or “simple” porphyries. This talk focuses on using both the CSV mineral data, as well as the hyperspectral image data to create robust domains from which to select geometallurgical testwork data from similar rock units.
