Eagle Mountain Mining (ASX: EM2) has identified a large high-priority porphyry-style targets defined beneath tertiary cover at the company’s 100% owned Silver Mountain Project in Arizona, USA.
A recently completed 3D seismic survey with Fleet Space’s ExoSphere solution had identified the porphyry-style targets supported by previous aeromagnetic and gravity surveys
Silver Mountain is located northwest of Phoenix and is positioned on the Laramide Arc, a northwest- southeast trending geological feature containing world-class porphyry copper mines such as Bagdad, Miami and Resolution in Arizona.
“The recent 3D seismic survey at our Silver Mountain Project has been a resounding success, significantly enhancing our geological understanding and propelling the project to a top priority for exploration activities,” CEO, Tim Mason, said.
“While historical indicators suggested the potential for large mineralised systems at Silver Mountain, younger rock cover hampered our ability to pinpoint deeper targets. The new seismic data has effectively unlocked this geological potential.
“These new findings highlight an unexplored, western target zone, well beyond the past exploration efforts that were focussed on the eastern volcanogenic massive sulphide horizon.
“Extensive mapping has identified encouraging alteration zones along with structures that may have acted as pathways for mineralised fluids originating from a large, buried, heat source and showing themselves as the extensive copper, gold and silver surface occurrences.
“Propyllitic alteration, found on the outer edges of porphyry deposits, was found at the bottom of previously drilled diamond holes in the area. These holes were terminated about 100 metres above one of the porphyry-style targets.
“The Silver Mountain property is exceeding expectations and has solidified its place in our exploration strategy moving forward.”
