Eagle Mountain Mining Limited (ASX:EM2) has intersected further high-grade mineralization at its wholly-owned Oracle Ridge Copper Mine Project in Arizona, USA.
Assay results have been received for 15 drill holes, with highlights including
− 25.5% Cu, 1,935g/t Ag and 15.2g/t Au over 0.6m.
“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,” CEO Tim Mason, said.
“These very high-grade zones demonstrate that the mineralization 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 programme 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.”
North-East Mine Area
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 intercept was within a bornite-rich, structurally controlled zone in the Escabrosa formation with the following spectacular assays: o 25.5% Cu, 1,935g/t Ag and 15.2g/t Au over 0.6m (WT-22-175)
This hole unfortunately deviated off target and intercepted an unsurveyed existing development drive, thereby not reaching the desired final depth. This result demonstrates the potential for additional localized high-grade structures which have not yet been identified by existing drilling due to the wider drill hole spacing.
Historic Daily Mine Area
The Daily mine area is entirely outside the existing resource. Drilling in this area was targeted at potential extensions to previously mined mineralization.
An underground survey is warranted to model the previously extracted areas and enable further targeting of mineralized zones. The Daily mine area has been flooded to an unknown depth for many years, which prohibits entry to map and sample the remaining mineralization. Until this area is dewatered, the only way to test it is by further drilling.
Historic Geesaman Mine Area
Six resource expansion holes (WT-22-173, 174, 176-179) were successfully drilled in the north-east of the existing mineral resource, near the historic Geesaman mine workings. The drilling intercepted some high-grade narrow zones which indicates that mineralization extends towards the north-east and Geesaman mine workings.
