gold economics, page-2

YTC say on their Projects web page;

[The Hera deposit is an advanced, high grade gold deposit with base-metal credits capable of generating high margin production revenues.]

Time will tell how true that statement is - it was probably made a good while ago.
Can I point out david25 - that not all the gold resource is as deep as these latest intersections you are ref to.
But the ASX has no shortage of examples where small companies run into problems developing gold orebodies.
