LMPA based on what the numbers I have been going over and what Phred6 and you have done. My estimate is about 201 ounces going by 9.6 hrs worked a day per person and 21 days available in December to work.
Phred6 broke down my numbers and came up with the following:
Using esitmated number of 30,240 yards for December, one gets the following:
@ .4 grams/yard, 376.23 ounces $526,718.72
@ .3grams/yard, 282.17 ounces $395,039.04
@ .2grams/yard, 188.11 ounces $263,359.36
@ .1 grams/yard, 94.06 ounces $131,679.68
So based on my calculations I am thinkg 201 ounces at around .24grams/yard average.
