I'm no sure I understand your confusion about UC's expenditures.  You should read the release again.  It seems quite clear to me that the first million spent was to earn the first 10% interest by March of this year.  UC not only spent the money for that committment, but has already spent $500,000 of the 1 million commitment required by 2009 to obtain the 25% stake at that time.

"As  per the binding LOI between UC and Spider, UC is required to incur exploration expenditures of at least an additional $1 million on or before the second anniversary date of March 6, 2009, in order to earn an additional 15% vested interest in the Property, bringing UC's interest level to 25%. To date $500,000 of the $1 million second tranche has been spent. Should UC exercise its full commitment to the McFaulds Lake Project Property Joint Venture Agreement it will earn-in up to a 55% undivided interest in the property."
