  1. La Escondida Gold-Silver Project (Sonora, Mexico) Presented to Meus Exploracion S.A. de N.V by Michel Gauthier Gardin Inc. Gardin Inc.

  2. La Escondida, Cumeral and Cerro Blanco: Three gold-silver projects in different tectonic settings (From Groves, D.I., Goldfarb, R.J., Gebre-Mariam, H., Hagemann, S.G., and Robert, F., 1998. Orogenic gold deposits- A proposed classification in the context of their crustal distribution and relationship to other gold deposit type: Ore geology Reviews, v. 13, 7-27). Gardin Inc.

  3. La Escondida (Sonora, Mexico) An orogenic gold-silver deposit Gardin Inc.

  4. What is the difference between an orogenic (epizonal) gold-silver deposit and an epithermal deposit gold silver deposit? Does’it really matter? Yes, for planning an exploration strategy! (From Groves, D.I., Goldfarb, R.J., Gebre-Mariam, H., Hagemann, S.G., and Robert, F., 1998. Orogenic gold deposits- A proposed classification in the context of their crustal distribution and relationship to other gold deposit type: Ore geology Reviews, v. 13, 7-27). Gardin Inc.

  5. Escondida: an orogenic (epizonal) Au-Ag-Sb deposit Jamesonite (Pb4FeSb6S14 ): The lead mineral at Escondida which indicates a characteristic Au-Sb epizonal orogenic metallic association Gardin Inc.

  6. Escondida: typical orogenic epizonal ore texture Gardin Inc.

  7. Obviously a compressional tectonic setting

  8. Saddle reef Western end of La Abundancia vein

  9. Close up on reverse faultWestern end of La Abundancia vein

  10. Stratabound veiningWestern end of La Abundancia vein

  11. Stratabound veiningEastern end of La Generosa vein

  12. Another type of target:Gold-bearing quartz veinlets stockwork in competent gabbro hosted by incompetent mudslates

  13. Kalgoorlie(Australia):A world-class orogenic gold deposit in such competent gabbro
