good evening Hoov my very good friend: The reason that I asked that qestion was that in only a few samples did I see anything approaching Onces per ton. I thank you for an excellent presentation on it.
As you know, in my checkered carrer I was an assayer. I am acutely aware of the problem of getting a true representative sample of the ore being processed or being investigated. The basic secret is the sample.
Generally I took a few hundred lbs of mine run ore and gradually reduced that by having my help reduce it in quarterly sections until I had just a few lbs. this was ground, to a fine mesh, generally 200, quartered and samples taken for assay and future reference puposes.
Reslts were in ppm =grams per ton.
Now where the ore is spotty with free gold, it is easy to get one pin sized spec of gold in one part of the sample and not the other which will throw the assay off. You can end up a Bonanza mine or a worthless piece of ground, figuratively speaking. Obviously, thie is an extreme example, since most asays are extremely accurate.
BUT it can happen, just as a drill can core a section similar to the ham in a ham sandwich without touching the bread.
