Aubrey Eveleigh's Zenyatta Ventures Ltd. (ZEN) slumped another 40 cents to $2.39 on 794,000 shares after Mr. Eveleigh waffled about when the company's preliminary economic assessment of the Albany graphite deposit in Northern Ontario would be complete. The dream sheet, originally expected early this year, is apparently hung up on metallurgical work needed to set the processing method. Mr. Eveleigh says "an estimated completion date will be better understood in the next six to eight weeks," after which he will update investors. (In other words, his target date for setting a target date is now two months off.) Stephen Mackie, manager of SGS Canada Inc., Zenyatta's hired metallurgists, is as fluent in bafflegab as is Mr. Eveleigh. He says SGS expects to "develop a distinctive process" for the Albany graphite, adding that "tweaking of a process flow sheet is quite common." The delays have Zenyatta's shareholders feeling tweaked, especially those that bought this spring at $3.60, or last year at $5. Mr. Eveleigh goes on and on about the uniqueness and rarity of the Albany deposit, probably because his pitch and Zenyatta's long-awaited dream sheet depend heavily upon the company selling its graphite for much more -- perhaps five times more -- than most producers get.
