The average grade of the five veins that Dynasty will set into production is 15,29 g/t. Mining 300 ton per day from these veins assuming 20 % dilution and 90 % recovery would give 51 681 oz per year. With cost of 40 musd this will mean a annual cashflow of 30 musd. 

In this environment with falling goldprices, high grade is crucial. Not many gold mines come close to the grades of Zaruma.
