RE: trivia questionThis is the conversion I use. ~0.76 cu meter = 1 cu yard. 35 cu meters = 45.8 cu yards. Let's stay in imperial units. THE MASS of one cubic yard of alluvium varies greatly with grain-size, moisture content, type of sand/pebbles etc. it is not an exact conversion. I have always maintained that placers are mined by volume, period. Evaluations should be carried out in volumes of material to be processed, not tons or tonnes. Read back in my posts, trying figure a mass for sand and gravel is not what I do. A volume of ground is a volume of ground, not dependent on moisture content, clast mineralogy, grain-size distribution, etc..... There is so much gold in each volume of ground, period. In the NI43-101 for Mkuvia the resource is stated in grams per "loose" cubic meter (as opposed to Bank Cubic Meter), a VOLUME. This is because the volume measured and tested was measured after it had been dug out of the pit.Anyway if one says sand is 2600 pounds per cubic yard then 35 cubic meters has a mass of about 60 tons... and it does not matter. I think in volumes because that is the correct, more realistic and accurate way to measure "ore" in a placer. Just my opinion, but a firm one. I fell into the trap of using mass and it just causes confusion, my bad.Not Investment Advice, DYODD, think in volumes.
