Lode or Placer: What Difference Does It Make?
September 2014 by Keith BowenThis explains the large difference in particle sizes between placers and hydrothermal lode deposits, but also means that while the mining may be similar in some cases, the sampling and recovery techniques are usually quite different.
Improvements in mining equipment and techniques, along with a higher gold price, make many mining properties profitable today that may not have been in the past.
In processing gold, silver and other valuable ores, the minerals containing the values, such as metallic gold, silver-bearing sulfides or other minerals, must be freed from the surrounding host rock before those valuable minerals can be captured.
So far this year we have recovered over three pounds of gold and the hard rock veins seem to go on forever. We now have three claims that can produce good enough gold to set up a productive operation.
Not long after this, I was camped out with the geologist beside the Similkameen River where he showed me the evidence that an ancient channel existed on our claim.
His findings were not exaggerated—after running 82 buckets of gravels in two days we had a remarkable 27.8 grams of gold!
There were nice sections of vein material at the end of several drifts, like they just stopped work one day and walked away.
With the exception of well-established operators with proven reserves and years of field experience, the high price of gold brought a flood of speculators, con men, and real estate brokers into the mix who were not previously engaged in the gold mining market.
