Continued advances in mining technology have the potential to reduce the extraction period of a mine nearly in half. A mine given a 30 year lifespan, with the adaption to new mining technologies, could see the mine's lifespan decreased to 15 to 20 years. This makes investing millions of dollars into permanent infrastructure not as ...
