Yup - exactly. I have to admit even though I thought I was visualizing rich ore pretty well in my head, it wasn't until I started doing examples for myself like this one that I started realizing how far off I could be.Joe Ribaudo wrote:Paul,
One other thing........The gold in that rock would not all be on the surface of the piece. Some of your quarter's worth would be hidden inside.
That's just a guess, so I could be wrong.
For me it goes to show 2 major things:
1) Most people would likely have a difficult time recognizing gold ore that assay's as high as $5K/ton because there would be so little visual gold to see unless you just happened to come across a section where the gold is completely exposed
2) More importantly, in order to properly assay a claim, one would have to crush a pretty large portion of ore and then take a representative sample to have assayed. Any "picking and choosing" rocks to crush based on visual interpretation could drastically over or under estimate the richness of the ore.
This is the main reason in my mind why I put absolutely no stock into assay reports of "dutchman ore" of any kind because it's highly likely those pieces were all hand picked (cobbed) and just the richest specimens taken. The most important aspects of the "dutchman ore" is everything BUT the concentration of gold. Tell me what the surrounding matrix consists of geologically and elementally and you have a much better image of the ore imho, which is just what Dr. Glover was trying to do for his book.
