Here let’s understand the geology of porphyries and iron oxide copper gold deposits or IOCG as they are known. These are somewhat the giants of the ore deposits world. As a mining interested learner, the geology of porphyry copper deposits is vital to your education. Now in the first Exploration Geology Course I discussed how because … Read more
What are the Differences Between SEDEX and VMS Deposits and how the VMS and SEDEX deposits fit into the overall scheme of things. You remember that nature concentrates the metals by a process of partially melting crustal rocks at depth, letting the metal rise through the crust and cool, dumping the valueless material such as feldspar and … Read more
While venturing into a gold mine is fun and exciting, it can also be intimidating and dangerous as all mines are underneath the earth’s surface in some shape or form. Working in a gold mine is no easy job as it will take extensive amounts of time and effort to find any pieces of gold. … Read more

How to explore or “go prospecting” for a Orogenic-Mesothermal-Greenstone Gold Deposit is described herein starting with what exploration tool can be used? First is magnetic surveys can be very useful exploration tools, when looking for bends and structures that the potential host Greenstone/Orogenic shear hosted gold deposits and mineralization. Gravity surveys can be very … Read more
IOCG Iron Oxide Copper Gold Ore Deposits goes with porphyries as they are also loosely associated with a large felsic intrusions and form at moderate depths, unlike the dominantly tertiary porphyries IOCG’s tend to be much older and are generally protoizoic in age from 1.1 to 1.8 billion years ago. There are some younger ones … Read more
