I've always assumed there were some investors waiting to see proof of a real revenue stream- especially after the red herrings previously (GHDC paid with "proceeds from the historic tailings", or this from a year ago: "Silver Falcon Mining, Inc. (SFMI) Converts Inventory of Concentrates to Cash Revenue").
SFMI's waste ore is indeed higher grade than the main reserves of many companies. But that's why those other companies have mills that process 1000s of tons per day and up. SFMI's present mill can make a profit at 3 g/t and 33 tpd, but it can't fund the rest of the operation. Which is why they are expanding the mill. But then they run into another limitation- the amount of ore they can haul down the mountain per day. They can only do so many loads, and only Mon-Thurs., and for the ore from higher elevation, only during the part of the year when the roads are clear. All of which is why they are in a rush to get started mining from the Sinker- Higher grade ore (hopefully much higher) that can be trucked down year round. 100-150 tpd of 1 oz/t ore is $60-90M/yr, 2 oz/t is $120-180M/year. For a company that is presently valued at ~$20M.
