THE DRILL SERGEANT: Eagle Mountain Mining (ASX: EM2) reported results of a field mapping program at the OREX prospect, part of the company’s 80 per cent-owned Oracle Ridge mine project in Arizona.
Eagle Mountain conducted the latest detailed mapping project based on encouraging results the company gained from an initial field mapping program carried out at OREX in 2020.
The recently completed field program confirmed the extensive occurrences of outcropping skarn hosted copper-silver-gold mineralisation along the lower contact of the Leatherwood intrusive and the skarn horizon.
Over 100 grab samples were collected with many returning high-grade mineralisation, including:
10.6 per cent copper, 29.5 grams per tonne silver
8.17 per cent copper, 71.3g/t silver, 0.48g/t gold
8.08 per cent copper, 30.9g/t silver, 0.23g/t gold
8.06 per cent copper, 39.1g/t silver
6.64 per cent copper
6.31 per cent copper, 0.45 g/t gold
6.21 per cent copper, 59.6 g/t silver
The company observed limestone formations and resulting skarn to be like those encountered at the Oracle Ridge mine.
“These results illustrate the prospectivity of the OREX prospect which covers an area greater than at the Oracle Ridge mine,” Eagle Mountain Mining CEO Tim Mason said in the company’s ASX announcement.
“Following an initial geological review in 2020, we staked a significant package of prospective land to the south-east of the Oracle Ridge mine now known as OREX.
“This latest field program on OREX concluded that the lower contact of the Leatherwood granitic intrusive has abundant outcropping copper skarn.
“Our interpretation is that the limestone units which host the mineralised skarn were intruded by the Leatherwood granite, therefore the bottom of the Leatherwood at OREX is highly prospective for further mineralisation.
“We have commenced a detailed drone aeromagnetic geophysical survey over OREX to assist us in defining priority drill targets.”
