Special Report: Recently completed Mobile MT geophysical survey identifies conductive anomalies at the Lynn Lake nickel-copper-cobalt sulphide project in Canada.

The survey identified a number of previously untested priority targets, which will form the basis for the next phase of drilling at the historically significant mining site.

Corazon Mining Limited (ASX: CZN) recently completed the MobileMT geophysical survey, with the innovative new aerial process a potential ‘game-changer’ in exploration for nickel sulphide at the Lynn Lake project. Lynn Lake has been described as one of the best nickel sulphide exploration plays in North America and the implementation of the latest survey tool has enhanced opportunities for discovery.

Initial interpretations of the data focused on the highly prospective Fraser Lake Complex located within Lynn Lake, where drilling by the company has identified mineralisation indicative of a large magnetic nickel-copper-cobalt sulphide system.

Use of MobileMT geophysical survey

Utilisation of the MobileMT survey process showed improved effectiveness over standard ground and aerial electromagnetic (EM) surveys, in differentiating magmatic sulphide conductors from non-economic conductors.

Previous EM surveys conducted at Lynn Lake were impacted by surficial conductive lake deposits and barren sulphidic sediments which essentially masked the geophysical signature of any potential nickel sulphide conductors.

MobileMT surveying was able to decipher many of the false conductors detected by EM surveying which, in conjunction with other geophysical data, subsequently identified new areas of interest for Corazon.

Drill targets at Fraser Lake

Multiple new priority targets were identified within the large ‘eye-like’ Fraser Lake Complex (FLC). The definition of new conductors at FLC has highlighted the prospectivity of the western extremity of the intrusive complex and indicates a deep-seated plumbing system linking several intrusive bodies.

Corazon had focused its current exploration of the area within the FLC with the knowledge that mineralisation intersected in its prior drilling is indicative of a large, long-lived magmatic sulphide system.

The MobileMT findings have identified new targets, with multiple additional new geophysical conductors still to be analysed. Detailed planning has begun for the next drilling program which is anticipated to commence at the end of this year.
