VAN DYKE COPPER PROJECT
Van Dyke - Arizona, USA
- Copper Fox owns a 100% working interest in the Van Dyke copper project, consisting of 531.5 hectares of mineral rights and 5.75 hectares of surface rights, located in the Globe-Miami Mining District, approximately 145 kilometers east of Phoenix.
- Van Dyke is referred to as an In-Situ Copper Recovery (ISCR) project that utilizes in-situ leaching to recover soluable copper. The ISCR process is currently in use in several other copper projects in Arizona.
- The 2019 analytical program involved updating the geological model and completion of an updated resource estimate, which has established for the first time an Indicated Mineral Resource.
Van Dyke Project:
| Category | Tonnes (Mt) | TCu (%) | ASCu (%) | CNCu (%) | RecCu (%) | Recovery (%) | Soluble Cu (Mlb) | Total Cu (Mlb) |
|---|---|---|---|---|---|---|---|---|
| Indicated | 97.6 | 0.33 | 0.23 | 0.04 | 0.24 | 90 | 517 | 717 |
| Inferred | 168.0 | 0.27 | 0.17 | 0.04 | 0.19 | 90 | 699 | 1,007 |
Cu=copper, Au=gold, Mo=molybdenum, Ag=silver, %=percent, gt=grams per tonne, Mt=millions of tonnes, Blb=billions of pounds, Mlb=millions of pounds, Moz=millions of ounces. Sue Bird, P.Eng., an employee of Moose Mountain Technical Services, is the QP. The effective date is January 9, 2020. The “reasonable prospects for eventual economic extraction: shape has been creased based on a a copper price of US$2,80/lb, employment of in-situ leach extraction methods, processing costs of US$0.60/lb Cu and all in operating and sustaning costs of US$1.25/tonne, a recovery of 90% for total soluble copper and an average Specific Gravity of 2.6t/m3. Approximate drill-hole spacings is 80m for Indicated Mineral Resources. The average dip of the deposit within the Indicated and Inferred Mineral Resource outlines is 20 degrees. Vertical thickness of the mineralized enverlope ranges from 40m to over 200m. Rounding as required by Best Practices established by the CIM reporting guidelines may result in slight apparant differences between tonnes, grade and contained metal content.
Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
