Find Out More About Geochemistry and Hyperspectral Data Analysis
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…

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…

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…

Haven’t conducted a pXRF program in awhile? No worries, this post has you covered… to remind you to never ever forget to calibrate your equipment. Like any geochemical program, you’re also going to need to setup a rigorous QA/QC program…

A common comment that we receive is that ‘spectral is great for porphyry and epithermal, but it cannot help with other deposits.’ At LKI Consulting, we wholeheartedly disagree with this statement so for our last Spectralucation July post we would…

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…

Fig. 1. Montmorillonite spectra celebrating Spectalucation July. The y-axis is reflectance (%) and the x-axis is wavelength (nm). Our blog posts thus far have concentrated more on geochemistry and general themes so we thought for July… let’s get into some…

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…

Accurate and consistent mineralogy is one of the fundamental building blocks of exploration. The explorationist talks and dreams about discovery – in order to do this, they must define vectors towards mineralization, while simultaneously de-risking and increasing the net present…

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…
