My brief summary of the linked subject.
I'm not sure if someone has already posted about TF here, this process appears to work well for narrow vein mining. Milling and transportation costs are reduced, the same amount of gold is produced from 100 tons of ore versus 1000 tons from conventional methods, easier on the environment, would also reduce the cost of building a mine and the time required to bring it into production.
