My only guess is that someone wants in, but few are selling. So the higher price. I've heard no new news.
Beware, however. Large price moves on low volume tells us nothing about investor sentiment. Until there's good news, the share price can fall just as quickly as it rises. 36 cents wasn't too long ago.
Warrick Smith indicated to me recently that news is forthcoming. Let's hope it provides a solid platform for moving ahead. Lots of gold came out of Mineral Gulch previously; and with $1200/oz gold in today's market, a lot more should be mined.
