I found the excerpt of Nevsun Resources below, interesting.

Nevsun Resources Ltd. (TSX:NSU / NYSE Amex:NSU) is pleased to advise that its shareholders have ratified the Shareholders Rights Plan that was adopted by the Company's Board of Directors on June 8, 2011. The Rights Plan was not in response to any specific approach or anticipated approach by a bidder however is considered prudent in today's market so as to allow the Board of Directors more time to maximize value, should there be a bid for the Company.

The underlined portion is of interest to me. It shows that they know they may be prey by all the M&A activity going on and are trying to better protect theirselves.

How does this pertain to SLI,you might ask?

Well, it further verifies that the seas are full of circling sharks, and that many gold juniors are ripe for eating. The sharks have to catch the prey to eat, But with SLI, Lori should be able to put the property right in front of the sharks mouth, making us an easier target and hopefully one of the first eaten (in terms of Tesoro or Vilcoro). An adage comes to mind " you can,t rape the willing".
