Chalco is ~1/3 copper, pyrite is iron sulphide which is worthless in this context.
Table 2 is what's important in this release and its not the prettiest, bottom 3 rows show chalco of 5% = ~1.5-1.8% copper very deep and only 1 metre wide.
Good that they're getting some small hits of copper and similar host rocks, this hole would be called a 'technical success' but also an 'economic duster'.
