Eagle Mountain boss Tim Mason keeps bringing the boom over at the company’s Oracle Ridge Copper Project in Arizona, with twenty of the latest 22 drills delivering significant copper-gold intercepts.

Following an update to the ASX on Monday, Mason told Stockhead that with results from 22 new holes already in the can, the prolific Talon – and its nearby mid-mine areas – are all showing the right signals for a strong resource extension and upgrade potential.

“Our exploration focus remains on the Talon area which is underpinned by our new geologic model supporting target definition.

Mason’s Aussie-listed Eagle Mountain Mining (ASX:EM2) is a strategic copper-gold digger focusing on the exploration and development of its advanced greenfield projects in the US Tier 1 mining jurisdiction of Arizona.

Mason says of the 22 new results testing the northern mine area only two intercepted narrow or low-grade mineralisation.

“This latest drilling over a 1.5km strike continues to deliver strong results that supports our thesis that Oracle Ridge has the potential to be a copper project of significance in the US.”

The Resource Upgrade hits include:

– 60.7m at 1.56% Cu, 14.15 g/t Ag and 0.32 g/t Au, including: 14.6m at 2.83% Cu, 27.54 g/t Ag, 0.51 g/t Au (WT-22-99)

– 4.5m at 2.79% Cu, 32.85 g/t Ag and 0.36 g/t Au (WT-22-96)

– 4.5m at 2.92% Cu, 29.14 g/t Ag and 0.66 g/t Au (WT-22-97)

The Resource Infill hits:

  • 3.8m at 1.80% Cu, 27.63 g/t Ag and 10.92 g/t Au (WT-21-76)
  • 10.6m at 2.63% Cu, 17.97 g/t Ag and 0.39 g/t Au (WT-22-90)

Of further note is a gold intercept of 1.0m at 40.0g/t Au and 3.16% Cu (WT-21-76) received in the Talon showing potential for localised high-grade gold vein anomalies in the Leatherwood.

Mason says the company’s new geologic model, backed by over 100 new drill holes, is being used to refine the resource estimate and is driving new and successful high-value targets particularly in the southern Talon region.

Oracle Ridge already has a JORC Mineral Resource Estimate of 12.2mt at 1.51% Cu, 16/gt Ag and 0.19g/t Au.

The southern Talon jurisdiction is Mason’s pick for the focus area for the digger’s key exploration activities in the short-term.

Wave Zone extension drilling           

Two drill pads have recently been completed at the southern end of the Talon. Drilling is now in progress on the drill pads completed at the southern end of the Talon and targeting the prospective Wave zone towards the historic Leatherwood mine.

The Leatherwood mine includes two tunnels extending for approximately 50 metres connected by an internal shaft. A shipment of ore in 1969 consisted of about 45 tonnes of hand-sorted ore composed of approximately 12% copper, 200g/t silver and 1g/t gold

“We are also seeing some very high gold values, which could provide attractive sweeteners for a future operation.”

Further updates

Meanwhile Mason says EM2 is moving quickly through the planned refurbishment of the existing underground mine which will fast track drilling from underground along with access to obtain samples for metallurgical test work. A contract is expected to be awarded in the coming weeks with underground operations to commence shortly thereafter.

The underground drilling is scheduled for a September quarter kick off with the average hole length approximately half that from surface, offering significant improvements in drilling efficiency.
