• Solitude TSF Spillway Options, BHP Copper Inc., Globe, AZ, USA
  • Several spillway alternatives have been proposed to BHP, including a dedicated solution for the Solitude Tailings Storage Facility (TSF). This option integrates a new primary spillway with the planned roller-compacted concrete (RCC) auxiliary spillway, providing a consolidated design approach.

• Independent Review of Hydrologic Study for Solitude TSF, BHP Copper Inc., Globe, AZ, USA
  • An independent third-party review of the proposed Tailings Storage Facility (TSF) spillway improvements identified several hydrologic deficiencies. The reviewers strongly recommend the adoption of an integrated hydrology–hydraulic two-dimensional (2-D) modeling package capable of simulating both processes within a single framework. In addition, they advise BHP to employ three-dimensional (3-D) modeling software in the design of the new spillway. This approach would optimize and validate energy dissipation within the stilling basin of the structure before flows transition into the natural downstream channel.

• Barrick, Pascua-Lama Project, Chile-Argentina
  • Wrote a proposal, managed job and did the water balance model for the tailings storage facility expansion, process ore plant and fresh water reservoir.

• Colorado University at Boulder, MTBE Concentration Project, California
  • Determined the future concentration of MTBE at 17 drinking water supply wells at City of Oceanside.

• Ausenco Minerals, Morocco OCP Project, Morocco
  • Determined the wet and dry years of precipitation and evaporation, and rainfall depths for 24-hour duration of various recurrence intervals (from 2-year to 500-year) and PMP extreme-event precipitation as well as the water balances for two tailings storage facilities.

• London Mining PLC, Wadi Sawawin Project, Saudi Arabia
  • Determined the wet and dry years of precipitation and evaporation, and rainfall depths for 24-hour duration of various recurrence intervals (from 2-year to 500-year) and PMP extreme-event precipitation.

• Greystar Resources LTD, Angostura Project, Colombia
  • Determined the wet and dry years of precipitation and evaporation, and rainfall depths for 24-hour duration of various recurrence intervals (from 2-year to 500-year) and PMP extreme-event precipitation as well as thickened slurry and return water transport system and water balance for tailings storage facility.

• Anglo Ferrous Brazil S.A., Minas Rio Project, Brazil
  • Designed thickened slurry transport system from the phase 1 plant (2,800 m3/hr of flow and 45 m of head) and phase 2 plant (7,750 m3/hr of flow and 45 m of head) to the tailings storage facility and Itapa pit (10,550 m3/hr of flow and 85 m of head) for 20 years long operation; and the raw water and return water transport system from the tailings impoundment and water reservoir to the phase 1 and 2 plants (10,615 m3/hr of flow and 118 m of head). Minas Rio mine will be the biggest mine operation in the world.

• Gustavson Associates, Contact Copper Project, Nevada
  • Estimated precipitation and evaporation frequencies.

• Central Sun Mining, Cerro Santa Rosa Expansion Project, Nicaragua
  • Determined water storage requirements behind proposed tailings dam for PMP, 100-year, and 10-year storm events in the case when discharge, as spillway, does not exist.

• Minera Hochschild Mexico S.A. de C.V., San Felipe Project, Mexico
  • Determined the wet and dry years of precipitation and evaporation, and rainfall depths for 24-hour duration of various recurrence intervals (from 2-year to 500-year) and PMP extreme-event precipitation.

• Romarco Minerals Inc., Haile project, South Carolina
  • Designed a diversion channel and sized the overdrain pipes for the dry filter tailings stack facility.

• El Mochito, Modified Conventional Tailings Project, Honduras
  • Modeled and designed pipe line for the slurry transport from the pressure reducer box to the tailings impoundment.

• El Mochito, El Dorado Tailings Project, El Salvador
  • Designed a spillway and stilling basin for the tailings storage facility dam.

• Bowman Flat, Anadarko Project, Wyoming
  • Designed, modeled and drafted a pumping system (150 gpm of flow and 300 ft of head) to pump filter washing water from the tank to ponds.

• Phelps Dodge Bagdad, Inc.'s (PDBI), Pit Dewatering System Project, Arizona
  • Designed a open pit dewatering system with a barge pump station on the bottom of the open pit and four booster stations (4,000 gpm of flow and 1,500 ft of head).

• Bellhaven Copper and Gold Inc., Cerro Quema Project, Panama
  • Designed, drafted and calculated quantities for temporary sediment control gabion structure.

• Xstrata Nickel Company, Falcondo 2008 Geotechnical Study, Honduras
  • Reviewed a long term geotechnical risk assessment for Falcondo 2005 Geotechnical Study and gave answer on question why design did not mach measurements during tropical depression Noel. Redesigned a proposed Hato Viejo emergency spillway width from 18 to 14 meters.

• Central Sun Mining S.A., Mina Orosi TSF Project, Nicaragua
  • Designed a corrugated metal pipe under road.

• El Mochito, El Bosque TSF Damand Project, Honduras
  • Designed a spillway control section for the tailings storage facility dam.

• El Mochito, Pozo Azul East Spillway Project, Honduras
  • Designed a spillway and stilling basin for the tailings storage facility dam.

• Phelps Dodge Bagdad, Inc., Master Plan for Leach Pumping System Project, Arizona
  • Designed consideration for upgrades of existing leach circuit pumping system. In the Master Plan study concluded that the existing raffinate distribution system (RAFF) cannot provide 14,000 gpm and they need new RAFF system which proposed in the study. Also the pregnant leach system (PLS) need to be modified to answer on desired flow capacity on way represented in the study.

• Anatolia Minerals Development LTD., Copler Tailings Dam Project, Turkey
  • Determined maximum and minimum pumping rates doing water balance study and size channels covered with Hydrotex fabric formed concrete linings. Designed and drafted ultimate leach pad drain pipe works, several temporary drainage ditches and permanent diversion channels, and calculated quantities for whole project.

• Western Mesquite Mines, Inc., Truck Shop Underground Utilities, Rainbow Pit Diversion and Leach Pad Expansion Diversion Projects, California
  • Designed, modeled, and drafted a fire protection system and consumptive use water system for Truck Shop.  Designed, modeled and drafted energy dissipaters for diversion channels.

  • Checked and drafted a drainage basins map for the project.

• Giant-Ciniza Refinery, Storm Drain System Extension Project, New Mexico
  • Designed and modeled a pump system for the storm drain system.

The projects listed above were undertaken and completed either by Anatekton or by its employees during prior employment with another company.
