While the following old article no longer includes most of the graphs, it none-the-less supports that discovery can have a profound effect on a company's valuation.  I believe, however, that it is misleading in using share prices instead of the capitalized value of the company because share counts can change (as we well know).  Capitalization is the total value of all stock issued times the stock price.

BTW, where one chart might display for you, the starting line on the bottom left is far higher than where LBSR would fall on this chart at this time.  

My point is, I've seen numbers of cases where discovery has caused valuations to increase by 125 million dollars or more soon after the announcement.  Since the LBSR share price is practically zero, and if drilling leads to a massive discovery such as we are expecting, that means that under current circumstances the share price could rise to around 3 cents.  

At the share price as it was a few moments ago, that could mean at least a 100X multiplier on an investment made now.  

For my part, I've been doing more than just thinking about that, but use your own judgment.
