man that is poor math 167 hours divided by 8 is 20 and 7/8 days of work. so that is about 3 ounces of Gold a day. had they ran 54 days the MSHA report showed for hours work per mill person at an 8 hour day that would have been 162 ounces of gold.
Black Rock Canyon mine was averaging .1202 grams of gold per cubic yard based on the numbers in the PR.
Also had PCFG been able to mined their goal of 75,000 cubic yards they would have mined 289.83 ounce of gold in that time frame. based on .1202 grams of gold per cubic yard.
So based on this news still some more fine tuning to go but my feeling on this is that they are headed in the right direction.
