nto chalcopyrite is a cobination or mixture if you will of copper (Chalco) and iron (pyrite)
And disseminated means spread or scattered so probably not too high of grade but spread through 30% of the core at say .40% with likely 1 or 2 grams of gold present throughout much of the core length near surface is very very good.
This will go up further I have no doubts providing the remaining cores are as I expect meaning similar to the first.
