  • Camimex (Cámara Minera de México) received the Responsible Industry award by CONCAMIN Foundation.


  • Radius Gold Inc. is preparing the phase 4 drilling program at its Amalia project in Chihuahua, operated by Pan American Silver Corp.. The program is to test down dip and lateral expansions of the high-grade mineralization in the San Pedro structure previously defined.
  • Brigadier Gold Ltd. informed the three first diamond holes of a 5,000 m program at its Picachos project in Durango have intersected the San Agustín vein up to 125 m below the Nuevo Carrito adit. The three holes test the same vein section at different levels, with the shallower first hole going through underground workings, and the other two intercepting 10 and 7 meters of quartz-carbonate veining respectively.
