“The devil is in the detail” – vein mineralogy and texture as an aid to explo...

Dr Tony Christie

Epithermal quartz veins can vary dramatically in terms of size, texture, mineralogy and metal endowment. Vein size does matter in epithermal gold exploration, but large vein size does not necessarily…

Toward a global Carlin-type gold exploration model

Dr. Michael Ressel

Nevada hails as the pre-eminent camp for sediment-hosted gold deposits, yet uncertainty in the age and regional processes responsible for its giant Au-only deposits have contributed to less effectual exploration…
