Ann: Interim Scoping Study Report shows expansion potential, page-74

Just a few more comments on Pharvest's excellent treatise on narrow vein stoping for those with an inquisitive streak/obsession.
There is quite a good video (from 12m to 15m) explaining the basics

The more I look this interim scoping study report, the more I am warming to it. Some of the other factors in its favour to help offset the economics inferior to the open pits alternative are:

• It is nearly all out of site. No prying eyes, sabotage temptations or regular visits to the Courts for new permissions
• There is such a huge resource that a 15% Cg cut off is possible, but this can be adjusted up or down on the fly.
• Operations would be 12 months of the year which most skilled workers would demand
• Operations could be single shift all the way up to 24/7 such that mine output could be linked to customer demand without any buffer storage.
• Just-in-time operations are big savings.
• Expansions of the Lulea plant, a Talnode Si plant, a licenced anode operation in the UK, export to the US would not be a problem for the mine.
