... ( Fig. 2 B). Within the Coleman Mine, the McCreedy East 153 ore body is connected to a contact-style mineral zone (Levack #4 ore body) via a zone of transitional mineralization that is both Cu- and PGE-rich (9 Scoop ore body) ( Fig. 3 ). The underlying footwall also contains a number of discrete...
