My summer hide away

[Richard Flanders]

We have two of these drill rigs that extract a 2" cylinder/core of rock, sometimes for thousands of feet. Another senior geo and myself lay out and look at the core and figure out the lithologies, alteration and mineralization - Cu, Mo, Au here. We document this info in the computer in an excel like log sheet then get young geo techs - ours are all from the Colo school of mines in Golden - to scan the core with a spectrometer, a magnetic susceptibility instrument and an XRF gun then cut the core in half lengthwise for sampling - an awful job to put it mildly. We end up sending tons of rock in supersacks to a lab for processing and analysis.
