Eagle Mountain Mining (ASX:EM2) has intersected multiple ‘high-grade’ zones following the return of assay from 15 drillholes completed at its Oracle Ridge Copper Mine Project in Arizona, US.
The company reports a single resource upgrade hole was drilled in the north-east mine area, which intercepted some of the ‘highest grades’ encountered at Oracle Ridge.
The following assays include hole WT-22-175 with 25.5% copper (Cu), 1,935g/t silver (Ag), and 15.2g/t gold (Au) over 0.6m.
Drilling around the historic Daily mine area consisted of 6 drillholes and returned ‘high-grade’ results including hole WT-22-172 with 3.20% Cu, 117.84g/t Ag, and 0.28g/t Au over 6.7m; hole WT-22-171 with 3.18% Cu, 27.85g/t Ag, and 0.08g/t Au over 5m; and hole WT-22-170 with 9.78% Cu, 66.40g/t Ag, and 0.22g/t Au over 0.9m.
Eagle Mountain reports 6 resource expansion holes were drilled in the north-east of the existing mineral resource, near the historic Geesaman mine working. The drilling intercepted some ‘high-grade’ narrow zones, indicating that mineralisation extends towards the north-east and Geesaman mine workings.
Eagle Mountain Mining Chief Executive Officer (CEO) Tim Mason says: “We are pleased to see more impressive high-grade assay results at our Oracle Ridge Project, including one of the highest copper and silver assays ever recorded. These very high-grade zones demonstrate that the mineralisation at Oracle Ridge is not uniform and there are areas of spectacular grade.
Could these zones be an indicator of a larger system or thicker areas in the vicinity? One key objective of the recently commenced underground sampling and mapping program is to assess the extent of these very high-grade zones which could have a considerable positive impact on the resource model and potential future mining operation.”

Eagle Mountain reports a mapping and sampling program has begun. The sampling program involves cutting a sawtooth pattern on the walls and taking continuous samples from the cut.
Additionally, underground drilling began in mid-January, with the aim of upgrading existing indicated resources to measured.
Slower than anticipated drill rates were achieved during January due to mechanical and water supply issues however progress has improved during February.
Eagle Mountain also reports additional drilling has been added to the existing program after assessment of ‘high-grade’ features observed in holes such as WT-22-175.
Eagle Mountain Mining is a copper-gold explorer focused on the strategic exploration and development of the Oracle Ridge Copper Mine and the highly prospective greenfields Silver Mountain Project, both located in Arizona, US.
