Eagle Mountain Mining Limited (ASX:EM2) has obtained further high-grade copper assays along the Western Talon at its 100% owned Oracle Ridge Mine Project in Arizona, USA.
Assays have been received for four drill holes and the remainder of one hole, completed in the Western Talon area.
CEO, Tim Mason, said results occur outside the existing JORC Resource and within a strong geophysical anomaly stretching over 750m. Assays include: o 5.8m at 2.72% Cu, 29.59g/t Ag and 0.72g/t Au (WT-21-33); within 16.6m at 1.87% Cu, 18.53g/t Ag and 0.51g/t Au o 7.6m at 2.20% Cu, 20.70g/t Ag and 0.25g/t Au (WT-21-34); and o 3.3m at 2.06% Cu, 22.48g/t Ag and 0.56g/t Au (WT-21-34) “These latest drilling results are significant as they not only provide further support for expanding our JORC Resource, but they confirm the prospectivity of the ‘Wave’ structure which hosts some of the thickest intercepts at Oracle Ridge,” Mr Mason said.
“Furthermore, the Wave zone, which is a feature within the Talon, is now interpreted to connect recent high-grade intercepts to the historic Leatherwood mine where mineralisation outcrops at the surface at the southern end of the mine area.
“While the Leatherwood mine is relatively small, the reported mined grades are spectacular suggesting potential for very high-grade copper mineralisation to also occur along the Wave zone.
“We have assays pending for 11 drill holes from the northern part of the Wave zone and further holes will be drilled as roads are established in this area. Unfortunately, assays have recently been delayed due to a crusher outage at the laboratory. The crusher has since been fixed and our results from the Wave are being expedited through to the assay.
“Our own modern core saw has been delivered to our Tucson facility and is being commissioned this week. We look forward to receiving further assays from the Talon which has continued to show strong potential to build our JORC Resource.”
The Wave Zone and Leatherwood Mine
The Wave zone is a recently defined feature which the company has intersected in recent drill holes at the Western Talon. Some of the best intercepts at Oracle Ridge have been observed in sediments adjacent to, and within, the Wave zone.
Previously reported intercepts along the Wave include: 28.9m at 2.34% Cu, 21.95g/t Ag, 0.37g/t Au in WT-21-32; and 1.5m at 1.37% Cu, 10.64g/t Ag and 0.38 g/t Au in WT-21-31.
The Wave feature is defined by the Leatherwood intruding along a gently dipping fault structure (Wave Fault) which has created favourable conditions for the precipitation of minerals from hydrothermal fluids.
Thick zones of mineralisation are observed within the Wave feature and remain open to the east. A new interpretation extends the Wave zone for over 500 metres to the historical Leatherwood mine at the southern end of the Talon area, where copper, silver and gold mineralisation outcrops at the surface.
