- RPA Report estimates that Emerald Isle contains an indicated resource of 2.22 million tons grading 0.625% TCu (total copper) at a cut-off grade of 0.03% TCu and 10 ft. minimum vertical thickness (27.5 million pounds of copper)
- Pre-feasibility study by Behre Dolbear & Company (USA) Inc.
- SXEW plant, small open pit mine, leach pad containing mineralized material, 3 small low-grade stockpiles and mine infrastructure/buildings/equipment onsite
- Estimated 12 months to production of 5 million pounds of copper/year, possible

The Emerald Isle Mine property consisting of 37 unpatented lode mining claims and 12 millsite claims and located 24km northwest of Kingman, in the Wallapai District, Mohave County, Arizona. An open pit mine and the existing SXEW processing plant operated at the site from 1995 before being idled in 1996 due to low copper prices. The majority of the infrastructure including the SXEW processing facility remains as well as equipment which may need repair or replacement.
The Emerald Isle copper deposit is hosted by Late Tertiary conglomerates and, to a lesser extent, by Quaternary alluvium and Cretaceous granitic rocks. Copper mineralization at Emerald Isle is in the form of mineralized lenses contained within a paleochannel a few thousands of feet long and up to 750 feet wide. The source of copper at Emerald Isle is interpreted to be the low grade porphyry-type copper mineralization at Alum Wash, about 3.5 miles northeast of the Emerald Isle deposit. The mineralization is characterized by dark blue to black rock similar to the Exotica deposit, a satellite of the huge Chuquicamata copper deposit in Chile.
Past exploration (seismic survey by Arimetco) results suggest that a paleochannel similar to the one hosting the Emerald Isle deposit may be present south of the current open pit.
