Your 4 points pretty well sum up why our household is involved with SLI (except we don't have an accountant living here).
Meeting fellow investors at the Edmonton Corporate Presentation upped my confidence level to buy more.
I have to give credit to the hub leaders and numerous others, in particular Primed, for keeping us in. The wait has been longer than we first anticipated and lack of news has made us somewhat uneasy at times, especially the excruciating wait for the drill permit. It is great to be able to rely on a very well informed board who have done excellent DD when the nay sayers speak up. Now there is a truce with our financial advisor. He won't take any credit if things go very well, and he won't take any blame if they don't. Any buy or sell decisions are ours! I can live with that.
The thought of making crazy amounts of money and being able to make life easier for numerous family members and local charity organizations makes the risk worthwhile.
