Fraser Lake Complex
The Fraser Lake Complex
Corazon has systematically explored the Fraser Lake Complex (FLC) – an intrusive mafic body situated approximately five kilometres south of the Lynn Lake Mining Centre – since December 2016, and believes it has the potential to host significant nickel-copper-cobalt sulphide deposits.
Exploration by Corazon at the FLC (including drilling, ground geophysics, downhole geophysics and geochemistry) has resulted in the discovery of a large magmatic sulphide system that has the potential to host significant nickel-copper sulphide deposits.
The FLC has physical and chemical characteristics that suggest it is prospective for hosting Lynn Lake style magmatic nickel-copper-cobalt deposits. Corazon’s drilling has confirmed this potential, consistently intersecting Lynn Lake mine-grade nickel-copper-cobalt mineralisation.
Drilling – FLC and Lynn Lake
The Company’s past drilling at the FLC delivered positive results which strengthened Corazon’s geological model for the target, as well as the belief that the FLC has the potential to host significant nickel-copper-cobalt sulphide deposits. It is noted, though, that the feeder zone(s) for this mineralisation have not yet been identified. With this aim in mind, the results of the recent drilling will enable the Company to further refine its targeting and interpretation processes for on-going exploration.
The most recent drilling program was completed in March 2018; it comprised three holes at the FLC and two holes at targets closer to the Lynn Lake Mining Centre for a total of 1,415m metres. Drilling targeted high-magnetic features generated from the modelling (inversions) of ground magnetic data (ASX announcement 13 March 2019). The targets within the FLC were located on the margins of the Matrix Trend, a high-chargeability IP anomaly generated from extensive magmatic sulphide mineralisation.
Although this particular phase of drilling did not enhance the prospect, overall the Company’s drilling to date has intersected broad zones of low-grade nickel-copper-cobalt mineralisation and identified a large “channel” of disseminated magmatic sulphide. The higher-grade massive sulphide feeder zone to this system has yet to be identified and the Company continues to work on determining cost effective methods to define such targets.
The best result from the recent drilling was from the top of holes FLC2018-018 with 4.5m @ 0.25% Ni, 0.13% Cu and 0.02% Co – this was the only portion of the drill program that tested the Matrix IP Anomaly.
