Barker,
You say, "Come 4 months from now, Mineralfields has the option of selling out their investors..."
This is not true as FT must be held longer to get the tax deduction. Regardless, MineralFields FT funds are held in limited partnerships that have a life of 1 ½ to 2 years, and on dissolution, assets are rolled over into Tyhee's mutual fund. (This, paraphrased from Dave Webb in a private communication with me).
Check out MineralsFields' website.
Cheers,
Baires
