I should add that a seventh revenue stream would be when the roaster gets closer to it's potentail optimum throughput. I understand this could be as high as 90-100 tpd but lets say be conservative and hope for a consistant 70 tonnes per day average over the long term. As demonstrated in the previous posts this would generate an additional possible $1,000,000 per month. To operate on a continual basis at this rate the company would have to increase the processing rate in the sulphide mill from 330 tpd to about 450 tpd, a very doable expansion and not that expensive, in fact this has been reviewed in the past prior to the lead/zinc market meltdown last year so plans exist. This expansion would also generate more reveneue from the sulphide mill which I haven't calculated.

I probably should take a crack at how much revenue is generated from the sulphide mill at 330 tpd plus at an expanded 450 tpd, the company does have historical records on recoveries and production and revenues for the lead and zinc concentrates. The amount will be significant and likely over $500,000 per month at the present lead and zinc and silver prices.
