Geometallurgy: Deportment

November 6, 2023

More than anything when I first heard about deportment, I liked the word, but I knew nothing about it. Therefore, my natural next step was to ask questions, read some papers, and generally learn more about it. The first thing…

Geometallurgy: Penalties and Credits

October 24, 2023

Blog miniseries along common themes are the best! Through the end of 2023 we are going to dive into geometallurgy from a geochemistry-adjacent perspective (keeping it simple, keeping it relevant, and hoping every geoscientist learns one small thing per blog).…

Orientation Survey: pXRF

January 25, 2023

pXRF has many applications both within and outside of mining and mineral exploration. In no industry has a vendor ever told a client to take the pXRF, point, shoot, and voilà – you now have a robust dataset that is…

Orientation Surveys: Rocks

January 19, 2023

Perhaps a bit unconventional for these blog posts, but I want this to revolve front and center around this amazing resource I found from ALS Labs in the depths of my hard drive… a periodic table of the elements that…

Orientation Study: Residual Soil Geochemistry

January 11, 2023

As discussed in our first installment, orientation studies should enable the selection of optimum field, laboratory and interpretation procedures. Ideally, these procedures should allow for the clear resolution of significant anomalous patterns, with as little overlap as possible between anomalous…

January: A Month of Orientation Surveys

January 4, 2023

Orientation survey. Of course you *should* know what this term means… you think to yourself… Stop googling for half baked answers and stay tuned this January to our blog, where we are going to break down this term and show…

Spectralucation July: Using Spectral Composition Data

July 21, 2022

If you are unaware, hyperspectral data is renown for producing mineral data; biotite, white mica, tourmaline, sulfates, carbonates, Fe-oxides… the list is long and diverse. However, spectral datasets also yield “composition” data, namely crystallinity and wavelength data. In this post…

Electrochemistry & Invisible Gold in Pyrite

June 22, 2022

Although characteristic of Carlin-type deposits, invisible Au in pyrite is also observed in epithermal (low- and high-sulfidation) and porphyry deposits. Some famous examples include Yanacocha (Peru), Pueblo Viejo (Dominican Republic), Brucejack (Canada), Lihir (Papua New Guinea), and Dexing (China). Perhaps…

Hyperspectral, Geochemistry & Gangue Mineralogy

May 19, 2022

In comparison to their more shiny (and valuable) mineral counterparts, gangue mineralogy tends to be unloved by geologists. In our rush to define grade for market releases, we lose sight of the fact that gangue mineralogy impacts our final product…
