I don't think the level of "interest" you may have heard about quite rises to what you may be expecting that to mean, but that's just me.
"In general though, don't you think that these jr. explorer deals favor the party with the funding?"
I'm not sure I can agree with that. I think it depends on what the claims holder believes he is holding, and how strongly he feels about the likelyhood for getting a deal done.
"Even if HM seems to have some of the biggest deposits in the world, without the proof (drilling), LBSR's bargaining position is not that strong."
"...not that strong? Compared to what? I'm not sure I understand what you are saying/asking. Every prospective partner is in the same position. That is, the risk is the same, despite the potential size of the reward. While the potential reward may be larger than at some other property, the chance for losing it all is the same. In one respect, then, the higher risk/reward ratio could as well mean a better deal for LBSR, so I hope you understand my confusion in regards to your statement/question.
