RE: For what it is worth
Well Nelson, it ain't worth a H3ll of a lot, frankly. "...a wall fell in"...my hockey loving soul if a "wall fell in...".
"...a wall that caved in and this matrial got mixed in with the load and wassent with the shipments."...is called "dilution" and is what routinely happens when you mine a 1 meter wide vein with equipment that requires a working environment of at least 4 meters in width and 5 in height.
With that knowledge, it is not too great a stretch to arrive at the comprehension of what I posted so many months ago concerning dilution, mining widths and applying the grades from a one meter wide vein to a 4 meter wide working width with a shot length of up to 5 meters? (think 3-Boom Jumbo Drill here)
The grade of mineralization from the one meter wide vein must be carried out and averaged through the entire volume of muck required to be shot with the round that takes the one meter wide vein of gold mineralized rock.
80 cubic meters of Solid Granite @ 4536 lbs/cu yd*
20 cubic meters of solid Quartz @ 4455 lbs/cu yd + ~ 200 lbs sulfides/cu yd*

100 cubic meters = how many ton?
* For Moneymaker and Goldbuyer: 1 cubic yard = 0.764554858cubic meters
Do the math: 1 meter wide gold mineralized vein x 5 meters length by 4 meters in height = 20 cubic meters of vein material with a grade averaging about 25+/- gpt Au ~ 500 grams Au.
Then you calculate the volume of wallrock required to remove that 20 cubic meters of vein material: 4 meters x 5 meters x 4 meters - 20 cubic meters (for the vein material calculated above) and you get ~ 80 cubic meters of worthless muck.
You then add the value of the 20 cubic meters of gold mineralized vein material to get a total of approximately 100 cubic meters -combined 'gold mineralized material and worthless wallrock- with an overall, equivalent, gold content of...wait for it....drum roll please....well, gosh, as Goldbuyer points out, do your own darned math! 100 cubic meters of muck containing, in it's entirety, 500 grams of gold and you get...? 80 cubic meters of granite and 20 cubic meters of quartz vein with their respective "weights" listed below...figure it out folks! LOL!
And Voila!
Suddenly it is not too awfully difficult to see why SL-EZ might not be in too large a rush to let you in on how many ounces of gold were recovered at the Kinross Kettle River Cyanide/CIL/CIP LOW SULFIDE GOLD RECOVERY PLANT! Do a little Googling and see if you can determine just how efficient is the average cyanide/CIL/CIP plant at extracting gold from "heavily sulfide bearing gold mineralized vein material".
Now, of course, one has to assume that competent miners would be trying very assiduously to remove that distinctive, sulfide mineralized, white quartz vein material as completely as possible from the granitic wallrock blasted into the muck pile.
Let's (contraction of 'let us' for Moneymaker and Goldbuyer) assume the (now laid off?) professional and dedicated miners at Bonaparte Lake have managed to un-dilute the gold mineralized material by only 20%.
Well, again and especially for Goldbuyer, who is such a diligent DD'er, do the math and post here what you get for the possible head grade of the 'gold mineralized rock' being dumped off at the Kinross storage area. After all Goldbuyer, as you stated, I am sure all of this is information readily available to the other investors.
It sure ain't what McKay or whatever his name stated is the "grade very difficult to find throughout the mine" or something like that.
