The Terneras East Vein has simply phenomenal grades for its good width of 2.05 meters. Per ECU's news release, they have already traced this vein for 200 meters by 600 meters. These dimensions put the tonnage for this vein at 738,000 tonnes. If our next step is a 1500 tonne per day mill, this ore will take approximately 16 months to process. At the veins Ag equiv grade of 59.32 oz/tonne, it is worth $1,043 per tonne at the current silver price of $17.59 per ounce. Using a 70% recovery rate and a 15% smelter cost, this rock should yield $620.85 per tonne. At a $50/tonne cost for extraction, processing and capital, this vein will yield a profit of $570.85 per tonne. At 1500 tonnes per day, that is $856,269 per day, and $312,538,220 per year profit. If ECU corporate and exploration costs are 40 million per year, this leaves 272 million dollars profit per year. This will provide most, if not all of the money needed to upgrade to the 5,000 tonne per day mill.

It is my opinion that ECU should perform a feasibility study on the Terneras East Vein only at this time as it relates to profit for a 1500 tonne per day operation. While they mine the Terneras, they could continue exploration and feasibility studies for the 5,000 tpd operation. They would then have generated the significant profits necessary to self pay for the 5,000 tpd mill without having to go to the predatory Canadian finacial firms for funds.
