Deep drilling at the Copper Creek project in southern Arizona has returned significant grades for
The company has completed 12 holes, totalling 25,886 ft., on the target, which lies beneath the Mammoth Breccia.
Starting at a depth of 1,730 ft. below the surface, hole 1 encountered 630 ft. of mineralization grading 1% copper and 0.031% molybdenum, including 130 ft. of 1.8% copper.
Hole 2 intersected 800 ft. of porphyry-related sulphide mineralization grading 0.95% copper starting at 1,800 ft. below the surface.
Hole 8 hit 1,190 ft. averaging 0.77% copper starting at 1,790 ft. This long interval included a 160-ft. interval of 1.7% copper and a 100-ft. interval of 2.25% copper.
The high-grade mineralization at Mammoth-Keel is localized in brecciated hangingwall contacts between granodiorite and southeasterly plunging porphyry dykes. AMT believes the zone represents a feeder zone to mineralization in the Mammoth breccia above it.
Previous work by AMT has already delineated significant reserves in the Mammoth breccia.
As part of the drilling, the company also drilled the American Eagle breccia, half a mile southeast of the Mammoth breccia. While results from the three holes showed lower-grade mineralization, it was also much closer to the surface.
Hole AE-1 hit 50 ft. (from 670 to 720 ft.) grading 0.94% copper and 0.022% moly, as well as 90 ft. (880-970 ft.) of 0.84% copper. Hole AE-2 hit 80 ft. of 0.63% copper starting at 900 ft.
AMT expects to receive an aquifer protection permit from the Arizona Dept. of Environmental Quality before year-end. The permit is essential to the company’s plan to build a decline.
In the boardroom, Peter Crossgrove has been appointed chairman and chief executive officer of AMT, John Hick was named president, and Richard Neal was made a director.
