Calgary, Alberta–(Newsfile Corp. – May 11, 2023)– Copper Fox Metals Co., Ltd. Coo CPFXF (“Copperfox” or “Company”), through a wholly owned subsidiary Desert Fox Copper Co., Ltd. is pleased to provide an update on the wholly owned Van Dyke Company’s In-Situ Copper Recovery (“ISCR”) project in the Grove-Miami Mining Area in Gila County, Arizona.
2020 Preliminary Economic Assessment (“PEA”) for the Van Dyke Island Project, prepared in accordance with National Instrument 43-101; (Click here for news release) showed an after-tax net present value of US$645 million and an internal rate of return of 43.4%, based on a 17-year mine life using a copper price of US$3.15/lb. The PEA recommended that the project proceed to the Preliminary Feasibility Study (“PFS”) stage. Based on this recommendation, we are pursuing a drill hole repair and testing program along with other activities listed below.
- Cascade Drilling and Technical Services (“Cascade”) has commenced surge, bail and pump testing at four boreholes.
- Projects for mineralogical, solubility, whole rock and trace element studies have been completed.
- Sampling of the Gila conglomerate for uniaxial compressive strength (“UCS”) testing for geotechnical purposes is planned.
Copperfox President and CEO Elmer B. Stewart said, “The results of the borehole remediation activities completed so far at Van Dyke have been encouraging. The objectives of the current work program are: It is to provide additional data on key technical parameters of the excavator.” Depending on the results of the current program of work, the next phase of work will involve planning a multi-purpose drilling program aimed at installing additional hydrogeological monitoring stations, upgrading or expanding minerals. Explore resource categories and obtain samples for additional pressure leach testing or geotechnical purposes. ”
Cascade has commenced work on four historic boreholes selected for surge, bail and pump testing. This work is expected to take approximately three weeks to complete, barring unforeseen delays. Liquids recovered from wells are stored in containers for disposal at regulated locations. Once the tests are complete, sampling is planned to investigate the chemistry of the groundwater. Successful completion of testing should lead to the installation of downhole hydrogeological monitoring equipment to collect hydrogeological data for future permit requirements.
Mineral solubility test
PEA focused on a 17-year mine life to extract soluble copper from the Van Dyke deposit. The deposit consists of an upper oxide zone (mainly malachite, azurite, chrysocolla) and an underlying transition zone (malachite, azurite, chrysocolla and chalcopyrite mixture), followed by a chalcopyrite zone (mainly chalcopyrite). copper ore) exists.
Five boreholes within Phase 1 (Leach Panels 1-5) of the PEA-mandated mine plan were selected for mineral composition, bottle roll testing, and both whole rock and trace element geochemical analyses. I was. A total of 65 sample locations covering a wide range of acid-soluble copper grades from oxide, transition and chalcopyrite zones within these five drill holes were selected for planned testing work. Upon receipt of the leaching test results, additional samples from the drill holes within leaching panels 1-5 and leaching panels 6-11 (Phase 2 of the Mine Plan) may be selected for study. Samples will be selected from our existing core facility in Miami, Arizona and are expected to begin in late May.
The Van Dyke Project development will access the subsurface by advancing an underground ramp into the Gila conglomerate that descends to a depth of approximately 250 meters below the surface and above the “leaching cap” that covers the Van Dyke deposit. is being considered. The program consists of collecting samples for UCS testing to evaluate the mechanical properties of Gila Conglomerate. Data from this study provide important information for determining the level, if any, of ground support required for underground works.
