Here are the equivalent grade numbers for ECU's news release today. Prices used are today's as follows: Au = $913, Ag = $17.18, Zn = $0.8559, Pb = $0.8071. The assays are for two sides of a ramp which cut the A4 vein at a depth of 550 meters.

Cut #1

Au = 4.04 g/tonne

Ag = 30 g/tonne

Zn = 0.13%

Pb = 0.13%

Width = 6.17m

Cut #2

Au = 4.84 g/tonne

Ag = 37 g/tonne

Zn = 0.05%

Pb = 0.16%

Width = 7.09m

Average Ag Equiv = 8.97oz/tonne

Average Width = 6.63 meters

Ag Equiv per 100m x 100m = 1,784,133 oz Ag

Metal Value = $154.10/tonne

Metal Value at 70% Recovery Rate = $107.87/tonne

This vein has excellent grades for its width and basiclly matches the Cantarranas Zone reported last week at 9 oz Ag Equiv per tonne and exceeds the grades of the other reported wide zones. Assuming this vein matches the Chicago in length and depth (400m x 600m) it would contain 42.8 million ounces Ag Equiv or 805 thousand ounces Au Equiv of which 685 thousand ounces are actual gold.

The NI43-101 reported that zones over 2.7 meters wide are in the bulk mining category, for which ECU's anticapated cost is $25/tonne. Again, if this discovery extends for 400m by 600m, it will contain 4,773,600 tonnes of ore (using 3 tonnes per cubic meter). If ECU's profit is $107.87 - $25 = $82.87/tonne, this vein alone will yield a profit of $395 million dollars. We also have blue sky potential as this vein and others are getting wider with higher gold content at depth.
