I´m not up to speed on the total holdings of Mineral Fields in PRB.

But I´m happy to know that there is possibly an equally strong holding by another very strong investment company: Pinetree Capital !

NR Feb. 03, 2010:

TORONTO, ONTARIO--(Marketwire - Feb. 3, 2010) - The Directors of Probe Mines Limited (TSX VENTURE:PRB) ("Probe") are pleased to announce the closing of the recently announced private placement financing for gross proceeds of $250,000 consisting of the sale of 500,000 Units sold at $0.50 per Unit. Each Unit consists of one common share and one common share purchase warrant. Each whole common share purchase warrant entitles the holder to acquire one common share for $0.75 for a period of two years after closing. All securities will be subject to a hold period of four months.

Proceeds of the financing will be used to continue the Corporation's exploration efforts in the McFauld's Lake area, as well as for working capital and new project acquisitions. Probe is currently evaluating exploration programs for the 2010 season on all of its McFauld's assets, including the Probe-Noront Resources Joint Venture claims and the 100%-owned Tamarack, Victory and McFauld's West Projects.

The private placement was completed with Pinetree Resource Partnership ("Pinetree") which currently owns 4,500,000 common shares of Probe representing 13.4% of the 33,566,472 issued and outstanding common shares. Upon closing of the proposed financing, Pinetree owns 5,500,000 common shares of Probe on a fully diluted basis representing 14.1% of the issued and outstanding common shares. The private placement by Pinetree was unanimously approved by the directors of Probe who are all arm's length to Pinetree.

And these shares were transferred recently to one of the richest Canadians: Sheldon Inwentash, the founder of Pinetree Capital:

.

So, I assume, Mineral Fields might be a big shareholder of PRB, but they are certainly not the only ones and can do what they want !

But if they get Sheldon on their side for any decision, I´m pretty sure they would be able to steer this boat in any direction they want.
