Gold Mining: Gold Mine Development World Gold Council
Gold mine development is the second stage of the gold mining process. It involves the planning and construction of the mine and associated infrastructure. Mining companies must obtain appropriate permits and licenses before they can begin construction. This will generally take several years, although this varies greatly depending on location.

How Gold Is Mined Gold Mining Process World Gold Council
The lifecycle of a gold mine. People in hard hats working underground is what often comes to mind when thinking about how gold is mined. Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well
