Transcript

  • 1. CERRO SAMENTAPorphyry Copper Project
  • 2. CALAMA LINEAMENTThe Archibarca Lineament is a well known structural corridorSeveral large copper deposits occur along this structure such asLa Escondida and Zaldivar on the Chilean side and Rio Grandeand Lindero in the Argentinean side of the border ARCHIBARCA LINEAMENT
  • 3. Exploration History• 1995- Mansfield discovered copper oxide mineralization along a roadcut• Teck start exploration in late 1995 early 1996 doing soil and rock sampling, Induced Polarization and ground Magnetic surveys• 1996- Geologic mapping at 1:10,000 scale and drilling of three DDH’s holes 612 m total• Suspended by legal problems• 1998- Codelco estimates 40Mt at 0.5 %Cu.• 2000- 10 wide spaced DDH totalizing 1200 m
  • 4. Marifil Current Activities• Data Compilation• Mapping and Sampling of trenches• Delineation of drilling targets
  • 5. Cerro Samenta Main Features• Good Location on regional structure• Good endowment• Near surface porphyry (breccias )• Typical alteration and host rock• Amazing infrastructure, paved roads, rail road, water nearby.• 40 Mt resources of Cu oxides at surface
  • 6. Quartz Monzonite porphyry
  • 7. Old Trenches showing mineralization
  • 8. Quartz Monzonite porphyryWith potassic alteration
  • 9. Breccia with mineralized clasts
  • 10. Panoramic view of trenches looking West
