I did a little more number crunching, and checked past posts. 143 cubic yards per hour is the maximum thru put @ 95% production. (Thanks Phred, I used your figures.)
In production situations such as this, you want to "push" material downstream in the process by at least 10%. So, that means PCFG's present excavation rate has exceeded the maximum required material input to keep the mill process running at peak capacity.
A second shift, or weekend work are the next logical steps to increase production. "Pam" (PCFG employee) innocently hinted at this when she was asked how many shifts they were running. She replied: "Just one for now."
I expect the expansion of the mill process will be expedited. It is now just a question of how fast they can get the precious metals separated from the aggregate, and how "rich" the aggregate is.
With the separation process being the limiting factor to the operation's profitability, it makes sense they have targeted the richer gravels for processing.
This all may seem a bit basic to some readers, but I believe it adds clarity and confidence regarding PCFG's reports. The only item that is somewhat open to question in this formula for earnings is the "richness" of the gravel they are presently processing. You can insert any predicted figure you feel comfortable with. (I know some of you have already run these figures for yourself.) Or, you can wait for the production reports to find out how "lucky" PCFG is.
Just my opinion, and a little real life expertise in material handling.

I just hang out here for the fun of it, that
doesn't mean I'm smart.
