Fingerprinting Archean part 4, doing things
Introduction: other chill things to do with clustered deposits Last time we went through the process of trying to identify clusters of deposits with similar geochemical anomalies. We were kind of successful, in that there appears to some correspondence between some “type deposits” and the clusters. Well, now we’ve got these clusters, so what are…

Fingerprinting Archean gold deposits using geochemistry, part 3: deposits
Introduction We’ve been talking about fingerprinting for the last two weeks (part 1 here, part 2 here), meaning taking some geochemistry data and using it to infer something about genetics of a deposit. Last time, we looked at what some of the correlations we can expect to find. In other words, the elements that might…

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…

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…

What kind of mineral deposits produce the most gold?
Recently I started working on a series of videos with Maura Kolb (Unicorn Exploration) about different kinds of gold deposits (check out the video on her channel). Right away we wanted to talk about, OK, what is the breakdown between deposit type and gold production? I thought that would be pretty easy to search for,…
