The Re-Os analyses show<br \/>\nages of 91.0, ~94, 104.6, and 107.2 Ma, over an apparent 16 M.y. period of mineralization.<br \/>\nAges for three of the six samples are identical within error (\u00b10.5 Ma) at ~94 Ma.<br \/>\nAges of 91.0 and ~94Malikely represent distinct mineralizing events, whereas the oldest<br \/>\ntwo ages (104.6 and 107.2 Ma) from disseminated molybdenite in skarn may indicate<br \/>\ndisturbance of the Re-Os system.
