Multiple Large Nickel-Copper-Cobalt Targets Identified (ASX announcement 27/07/16)

  • Fraser Lake Complex (FLC) Induced Polarisation (IP) survey identifies:
    • 20 high-priority targets defined with very strong-IP anomalies
      • 12  targets interpreted to come close to surface (under shallow cover)
      • Most display good depth extents (+700m below surface)
      • More than 30 second-order targets with strong-IP anomalies
  • Walk up drill targets identified
  • Chargeability IP anomalies trend off survey area, towards interpreted feeder zone to the intrusive complex – an untested Voisey’s Bay style target
  • FLC is only 5km from Lynn Lake, historically one of Canada’s most prolific nickel producing mining centres:
    • FLC twice as large as the Lynn Lake host intrusion, and
    • Anomalous in nickel-copper sulphides (past sampling and drilling)
  • Targets predominantly under shallow cover.

 

Corazon recently announced the completion of detailed interpretation and analysis of Induced Polarisation (“IP”) and Resistivity ground geophysical surveys at the Fraser Lake Complex (FLC), located within the Company’s Lynn Lake Nickel-Copper-Cobalt Sulphide Project.

The results are highly encouraging, with this recent work identifying numerous anomalies with similar IP characteristics to known mineralisation within the Lynn Lake Mining Centre, situated just 5km to the north (Figure 1).  Corazon believes these anomalies are representative of nickel-copper-cobalt sulphide mineralisation and that the FLC has the potential to host a mineralised system similar to Lynn Lake, historically one of Canada’s most prolific nickel producing areas.  The FLC intrusion is twice the size of the Lynn Lake host intrusion, and the area containing priority IP targets within the FLC is larger than the mine area at Lynn Lake.

IP Survey Results

The priority geophysical targets have been selected on the basis of their chargeability strength, resistivity association and their characteristics, in terms of geometry, source depth and vertical/horizontal extent.

Twenty (20) high priority targets have been identified in the surveyed area, which are of significant strength and depth extents to warrant drill testing or further exploration follow-up.

As many as thirty-one (31) lower priority targets have also been selected, showing similar geophysical characteristics to the high priority targets. These targets are ranked lower because they generally lack detailed Pole-Dipole IP coverage or display poor or inconsistent line-to-line correlation.

The IP responses at FLC have been differentiated based on their strength and associated resistivity.  Expected response for disseminated style mineralisation is characterised by increased chargeability and associated high/contact resistivity.  Massive sulphide style mineralisation is typically characterised by increased chargeability and low resistivity.

 

The anomalies identified at the FLC are generally sub-vertical and extend from near surface (potentially outcropping) to significant depths (+700m).  Strong to very strong IP anomalies appear to be enveloped by moderate values, likely representing strongly sulphide zones within a halo of weaker mineralisation.  This signature is typical of the Lynn Lake style of mineralisation.

 

Though the main targets identified by Corazon’s recent work have not previously been tested by surface geochemistry or drilling, past exploration has shown the FLC to be fertile with nickel mineralisation.
