Ann: LLO Reports Additional High Grade Intercepts at Tuvatu, page-5

i'm new here,
don't get the low trade volumes and low SP, is it just that no one is bothering to trade and holds because it is a huge find?
the result are consistant and very high grade, don't recall seeing any higher.
I think it will be costly and hard to mine on location ?, are there environmental concerns to covert to a full mine
can anyone shed light on why all things seem be stangnating on SP,
