Drilling on The Carlin Trend

I have once again been out in the field getting drill sites ready for drilling. Sometimes this will involve a rather quick trip out to a drill site, sometimes it can involve a few days or several half days spent locating sites on the ground using a GPS, staking the sites, and then getting a cat operator in for pad building. Sometimes sites have to be relocated due to inaccessibility. The weather has overall been good: not too hot, not too cold.

The place I work has had mining going on for a long time, as have many mines and districts along the Carlin Trend and Battle Mountain-Eureka Trend of mineral deposits. Although most mining at Carlin, itself, didn't begin until 1961, minor discoveries were made there in the 1870's and early 1900's, including discoveries of some small placer deposits. In general, gold was too fine-grained at Carlin for the old-timers to find it or do much with the minor amount they found.

Sometimes called "invisible gold" because it can usually only be seen with an SEM, the gold on the Carlin Trend is nothing like Geotripper's gold from The Mother Lode of California.
