Fingerprinting Archean gold deposits using geochemistry, part 2: correlations
Introduction Last week, we explored the idea of different ways of using geochemistry of other elements while exploring for Au. Geochemistry helps to: The key to all of that is to understand what elements associate with Au, and what do their relative concentrations and behaviors mean. We came up with a starting list of elements…

Fingerprinting Archean gold deposits using geochemistry, part 1: introduction
Fingerprinting refers to the use of conventionally collected geochemistry data to enhance our ability to explore. We want to know the fingerprint of gold mineralization, so we can use other, better behaved elements as proxies for gold. We also want to understand the genesis of mineralization so we know how to vector in the deposit.…

Sorting out your deposit: ore sorting technology today and tomorrow
Introduction This week on Unicorn Exploration, Maura and I were talking about lower grade Archean gold deposits. One thing that came up was the application of ore sorting and how that helps to change the economics of some deposits. Today I will go over ore sorting, a technology that can effectively increase the grade of…

The fault valve model part 2: how to use it to find deposits
Last week, I wrote about the fault valve model and how useful it is for thinking about orogenic gold deposits. This time I want to try to put some of what we learned to good use and try to find some gold deposits. Reminder: 1) We are looking for zones of lithological and structural…
