Spectralucation July Beyond Porphyry Epithermal

Spectralucation July: Beyond Porphyry-Epithermal

July 27, 2022

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…

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…

De-risking the Mining Value Chain Using Hyperspectral Technology

May 31, 2022

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…

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…

Where’s Your Champion At?

March 22, 2022

Geologists are busy – at site the number one priority is ensuring cohesion and completing the daily / weekly / monthly(?) task list. The introduction of new technologies and even the interpretation of relatively standard programs, such as 48-element geochemistry…

The Importance of Using Data to Log Core

January 4, 2022

Although the enargite is obvious, the white rock… less so. Using tools, such as hyperspectral can help resolve this for fundamentally better models. Over the course of a project hundreds of thousands to millions of meters are collected, representing a…
