Geology, Methods & Mineral Systems
Reference articles on mineral exploration, deposit geology, field methods and British Columbia’s mineral systems—providing context for the terminology and technical concepts used throughout Eastfield’s public project information.
The Knowledge Centre provides general educational information about mineral exploration. For information concerning Eastfield's mineral projects, readers should refer to the Company's project disclosures, news releases and continuous-disclosure filings on SEDAR+.
Deposit Geology
Understanding Porphyry Copper Systems
Porphyry deposits are the world's primary source of copper — large, low-grade systems that form above cooling magma chambers in volcanic arcs.
Read articleMagmatic Nickel-Copper-PGE Deposits
How sulphide-rich magmas concentrate nickel, copper, cobalt, and platinum-group elements — and why these critical-mineral systems are increasingly sought after.
Read articleOrogenic and Epithermal Gold Deposits
Two of the most important gold deposit styles — structurally controlled orogenic veins and shallow epithermal systems — and how explorers find them.
