A Confederacy of Underachievers For what it's worth (well, about 2 cents I guess) it appears that five of Yale's six partners in its several Mexican ventures have negative EPS -- only Mammoth, which is working the Urique Project (at 71,000 acres, Yale's largest) seems to have positive EPS (tho' barely). It's all part of the exploration game, I know, and maybe one day Yale will hit pay dirt, but, hell's bells, it's a test of an investor's patience.
