On Exploration

  • Odyssey Marine Exploration Inc. announced that the environmental permit for dredging to proceed at its offshore San Diego phosphate project in Baja was denied. On the bright side, the permit was denied on grounds of only one issue: the potential impact of dredging operations on sea turtles. Oddissey will now work on the subject and engage with the authorities to keep the project on track.
  • Golden Tag Resources Ltd. announced its intention to acquire Golden Mineral’s 50% interest in the San Diego Silver Project in Durango, to hold a 100% interest in the project on completion of the agreement.
