Medusa Mining Limited (ASX:MML) has revised its production guidance lower for its Philippine affiliate mines.

For the March 2017 quarter, gold production returned a higher grade than expected, with production falling short of estimates to 56,897 ounces.
Medusa Mining says the three month result was impacted by higher rainfall, shaft restrictions and absenteeism.
