Nickel North Exploration Corp. (TSXV:NNX) announced results from an airborne electromagnetic survey at the Hawk Ridge nickel-copper-platinum group elements in Canada.
As quoted in the press release:
Although massive pyrrhotite-rich nickel sulphide bodies are always highly conductive and usually magnetic, analysis of the VTEM responses over the known copper-rich mineralized zones and deposits at Hopes Advance Main, Gamma and Pio Lake has shown that they possess their own distinctive geophysical signatures. The new data shows them to be strikingly less conductive and magnetic than typical pyrrhotite-rich nickel deposits, even when good metal grades and thicknesses are present. This is encouraging because this geophysical contrast is likely due to the predominance of the non-magnetic and moderately conductive copper sulphide host mineral, chalcopyrite, which is common at Hawk Ridge. Additionally, the deposits in question are predominantly hosted within weakly magnetic to non-magnetic gabbro rather than magnetic ultramafic rocks.
