I' thinking that would not be correct only because MSHA shows 2279 total, then you are using 6674 but they are stating 150 hours.. am I making sense? So to use a multiplier


2011 3 30 Mill Operation/Preparation Plant 2279 compared to


2011 4 30 Mill Operation/Preparation Plant 6674

so really.. 2279 divided by 50 ounces really took 45 hours per ounce if I was to really simplfy

6674 divided by 45 hours would be a guess of 150 ounces? for 4th quarter for a very broad prediction

Or am I just so confused that I can't do very simple math LMAO...Math was never my strong suit before anyone yells at me :)

So if we were to predict triple the hours again to 20,000 divided by say 40 hours to get an ounce we might be at 500 ounces for 1st quarter?

I'm going to need a drink this afternoon Trapper if you subject me to any further calculations!

I think you went to nobody's math class. The number of hours worked is not directly related to the output. The number of hours the mill runs is the important number. The plant output is 150 yards per hour. If they work a 10 hour day that's 1,500 yards per day. If they work a five day week that's 39,134 yards per month. They get approximately $1,400.00 an ounce from the refinery. So they get the following monthly numbers based on the recovery rate:

@.4 grams/yard, 486.88 ounces, $681,632.69

@.3 grams/yard, 365.16 ounces, $511,224.52

@.2 grams/yard, 243.44 ounces, $340,816.35

@.1 grams/yard, 121.72 ounces, $170,408.17

Let me head off all the other math whizzes and say these are rough numbers and don't take into account equipment failure, lack of tires, life belt drills, et al. The break even point is right around .15 grams per yard. What the MSHA numbers tell us is that they are working 50 hours per week which is good.
