Orogenic gold deposits exhibit spatial association with crustal-scale faults and are the product of protracted deformation and hydrothermal mineralization. A common theme to large deposits is the superposition of vein systems within the same fault network. The introduction of quartz/carbonate Read more... about The Role of Pre-Existing Veining in the Localization of Auriferous Vein Systems: Examples from the Canadian Shield

The mining industry responded to the public’s concerns about the use of cyanide by developing the International Cyanide Code to allow companies to demonstrate their commitment to safe, responsible use of cyanide. The Code was created by a multi-stakeholder process that included the participation Read more... about An Introduction to the International Cyanide Code

The last two decades have seen a significant evolution in the approaches used to close gold heap leach pad facilities in an environmentally responsible manner. With the promulgation of new cyanide regulations in the State of Nevada, USA in 1989, the mining industry was faced with the need to Read more... about The Evolution of Cyanide Heap Leach Closure Methods

Ore deposits occur in a wide range of tectonic settings, and are highly variable in their local characteristics. In this paper, we focus on the distribution of copper and gold deposits in the Southeast Asia region, and investigate large-scale plate-tectonic controls on the distribution Read more... about Tectonic controls on the distribution of large copper and gold deposits in Southeast Asia to identify productive and non-productive structures

There are over 45 cave mining projects in various stages of studies and development around the world. Cave mining methods will be the underground method of choice in the future. It is only relatively recent that this mass mining method, despite 70 years of use, has begun proving its potential. Read more... about Caving Cu-Au Porphyry

SRK conducted a geological and geophysical modelling study of Darlot-Centenary Gold Mine, Western Australia. This study defined geological boundaries where drilling was limited, allowing for targeting of potential extensions.
