If the drill/ trench results come in no good - I think she is forced to disclose that quickly to investors. She would not dump her shares while holding onto that information as that is illegal. Once the 'flood' of press releases start she (and all other insiders to the company) will probably be in a trading black out. And it could last several months. I think Lori is planning ahead for her own cash flow purposes. I assume she has a ton of stock options and other stocks and this sale is not a lot to her in the bigger picture.
