I calculated the %Cu based off the visual estimate of 0.2% chalcopyrite which is ~34% Cu

Okay, I get ya. given the true width is 25%, roughly speaking, can we say copper grade for the true width is ~0.3%? (assume %Chalcopyrite is consistent in this mineralization trend)
Chalcopyrite intersection is from 423-438m, hence an interval of 15m. If true width is 25%, then it should be 15*25%=3.7m interval at ~0.8% Visible Chalcopyrite (0.2%*15/3.7); Assuming 35% copper content within Chalcopyrite, this intersection should give us 3.7m @ ~0.3% copper.
