Here's just one example of how a little good news can make a big difference for a junior mining company.

On Feb 27, Banro (BAA) announced the completion of signed definitive agreements for two gold forward sale transactions.

On Feb 26th, before the announcement, BAA traded between 14.6 cents and 15 cents a share (USD). On the afternoon of Feb 27th, after the news, BAA traded between 15 cents and 24 cents. Today it reached 25.9 cents.

From Thursday's low to today's high the stock moved over 75%.

One might argue that a completion of the Sutter RMB deal could be an even more significant announcement for Tyhee!

Time will tell.
