Drilling and Drill Results

If you really want to know what’s down there you have to drill. Read articles relating to mineral exploration drilling and interpretation.

  • Ivanhoe Mines Kamoa-Kakula Project

    When we write about great deposits they are most often well known mines with long established pedigrees and histories of daring exploration in isolated locations. But not all great deposits are located in the middle of nowhere. Nor are they all behemoths f...

    Down-hole Geophysics in Mineral Exporation

    Overview During early exploration, particularly in ‘greenfield’ areas away from mines or known mineralisation, very little information is known about the rocks.  If an exploration company has the budget to drill a few holes and conduct an airborne or groun...

    Lies, Damn Lies and Drill Highlights: A Critical Look at Interpreting Drill Results

    That’s the problem. Not every drill result is good.  As investors we must evaluate public results with a critical eye an approach every mining company news release as questionable. Our investment depends on it. For junior miners, especially those wit...

    Reverse Circulation (RC) Drilling

    Reverse circulation or RC drilling is a fast and inexpensive method of drilling, particularly compared to diamond drilling. A hundred metres or more of drilling is possible  a day. RC is a commonly used drilling method in the mineral exploration industry. ...

    Why Drilling Is Essential in Mines

    The phrase “exploration geology” calls to mind a lonely geologist and a drill rig in the middle of a windswept, rocky expanse miles away from civilization. While that is the case in some instances, exploration geology activities are not  restricted only to...
