PolarX discloses 9.8% copper grade in 24.8m interval at Caribou Dome
Recent drilling at Caribou Dome yielded higher-grade copper than historical data, challenging the company's existing resource estimate.
PolarX reported two high-grade copper intervals during its latest campaign at Caribou Dome in Australia. Drill hole CD26-007 delivered 24.8 meters grading 9.8% copper and 14.5 grams per tonne silver over a depth of just 2.4 meters. A second interval in the same drill, covering 4.9 meters, returned 13.6% copper and 20.4 grams per tonne silver. Hole CD26-004 yielded another two intervals totaling 22.6 meters at an average grade of 8.1% copper over 3.7 meters. These results contrast sharply with historical drilling data from the 1960s and 1970s. The historic DH41 hole produced only 15.3 meters at 6.2% copper over an estimated true width of 4 meters. PolarX stated that the new grades suggest its existing mineral resource estimate may be conservative. Known mineralization currently extends approximately 500 meters below the surface. The company noted that further extensional drilling and an additional 1700 meters of core were planned to continue evaluation.
