this is pretty new to me and i'm not sure how to read these gravity tests. does the Head Calc g/t represent total recovery for both gravity and cyanide or do you add the CN feed g/t to the head calc?? The head calc adds up to about 1.72 g/t average (pretty good)....if you add the cn feed it takes us over 2gr/t....if these are just random samplings and represent an average of our core samples this could be very good but i really dont know what the heck i'm looking at here. can someone help?

In addition, the minimum overall gold recovery from gravity and cyanidation as shown in Table 2 below ranges from 96.8 to 99.6%.
