DOWNHOLE EM IDENTIFIES MULTIPLE CONDUCTORS AT LYNN LAKE
PRIORITY NICKEL SULPHIDE TARGETS DEFINED
FOR NEXT PHASE OF DRILLING
-
The initial phase of the 2021 drilling campaign has been completed
-
Drilling intersected favourable host rocks and extensive indications of magmatic nickel-copper sulphide mineralisation
-
Downhole EM (DHEM) geophysical surveys in progress
-
Multiple “off-hole” EM conductors have been identified in the target area - potentially indicative of sulphide bodies
-
Conductors represent high priority targets for the next phase of drilling
-
DHEM program is ongoing - plans for the next phase of drilling will be formalised after the DHEM program is complete
Corazon Mining Limited (ASX: CZN) (Corazon or Company) is pleased to announce initial findings from the first phase of its 2021 drilling campaign at the Lynn Lake Nickel-CopperCobalt Sulphide Project (Lynn Lake or Project) in Manitoba Province, Canada.
Corazon completed three holes for a total of 1,482 metres in this phase of drilling at Lynn Lake (Table 2), resulting in a successful first-pass test of a new target area west of the Fraser Lake Complex (FLC – figures 3 and 4). Drilling also confirmed MobileMT’s effectiveness in identifying areas most favourable for magmatic nickel-copper-cobalt sulphides at Lynn Lake.
All holes drilled within the target area west of the FLC (figures 1, 2, 3) have intersected favourable host rocks and extensive indications of magmatic sulphide mineralisation. Details of the results of each hole drilled in this phase of drilling are provided in this announcement.
Downhole Electromagnetic Geophysical Survey (DHEM) Underway – Delivering Results
With drilling now complete, Corazon is conducting a DHEM program of holes on this phase and previous phases of drilling. DHEM will more accurately define conductive bodies close to drill holes, within larger areas of anomalism defined by the aerial surveys.
To date, DHEM has been completed on five holes and identified 10 new conductors of substantial size (Table 1, figures 1 and 2) which may represent sulphide bodies. These anomalies will be priority targets for the next phase of drilling and underpins the potential for the entire conductive trend, identified by MobileMT, to the west of the FLC.

Corazon’s Managing Director, Mr Brett Smith, said:
“ The aerial MobileMT geophysics identified a large area of conductance, previously not recognised as prospective for nickel-copper sulphides. Our first round of drilling in this area intersected the right rocks and some good magmatic sulfides that enhances the potential of the target area. Now, with the detailing of DHEM conductors of a good size, that support the MobileMT interpretations, we have expectations that this large conductive trend to the west of the Fraser Lake Complex has the makings of a nickel-copper sulphide target area similar in size to the Lynn Lake mining centre.”.
The definition of the DHEM conductors has confirmed the effectiveness of MobileMT as an exploration tool for Lynn Lake style mineralisation. Analysis of the DHEM data has focused on the identification of responses that could indicate larger bodies of magmatic sulphide. Plates of interest have been chosen on the basis of their longer wavelength response, in preference to shorter wavelength characteristics of smaller bodies.
The DHEM program is ongoing, targeting other holes drilled by Corazon in previous phases of drilling. The greater conductive area west of the FLC and the DHEM plates defined will provide priority targets for the next phase of drilling.
On completion of the DHEM program, Corazon will formalise plans for the next phase of drilling and will provide details in due course.
Results of Drilling and Down-Hole Geophysical Surveys
The current program included three core drill holes for a total of 1,482 metres (Table 2). This drilling is the first test of conductive trends identified by the aerial MobileMT geophysical survey system.
Subsequent to drilling, these drill holes were probed using down-hole electromagnetic geophysical tools (DHEM), with the intention of more accurately defining the location and size of conductors drilled (in-hole) or close by (off-hole).
The effectiveness of DHEM in testing hole #24 has initiated the testing of additional holes in the area. This work has resulted in the identification of conductors, some similar in size to the high-grade deposits within the Lynn Lake Mining Centre.
Holes #23 and #24 prove the large conductive trend west of the FLC holds the potential to host multiple conductors indicative of nickel sulphide deposits.
Hole #24 was the first pass test of the MobileMT conductive trend. It intersected good widths of favourable gabbroic rocks, with strong indications of magmatic sulphides. The area tested was strongly sheared, indicating long-lived tectonic activity. A small zone of strong sulphide mineralisation interested by the hole (ASX announcement 4 March 2021) was nickel poor, did not generate any in-hole conductance from DHEM and is believed to be the result of remobilization of sulphide along faulting/shearing. This sulphide mineralisation is potentially related to the pipe-like/fault-controlled conductive trend identified by the small conductors 24A, 24B and 24C (figures 1 and 2, Table 1). Conductor 24D is more representative of the size of a mineralised body being tested for at this site. At a size of 96 metres by 56 metres, it supports the MobileMT anomaly and provides a definitive drill target for the area.

Hole #26 trended off-target and went over the top of the interpreted conductor. This hole was terminated at a depth of 440 metres, due to it deviating significantly off target. The DHEM of this hole failed to identify any conductors of note and due to the holes deviation, this area has yet to be adequately tested and follow-up work is required.
Hole #29 tested the strong South Pipe conductor located approximately two kilometres south from holes #24 and #26 (Figure 3). Results from this drilling are generally inconclusive, however, the Company believes the South Pipe area remains very prospective and additional work is required to advance this target.
The hole was stopped at 557 metres (planned depth of 720 metres) so that DHEM could be completed. Drilling had intersected extensive tectonic and hydrothermal breccias within the country rock (volcaniclastics and sediments). Some of these breccias contained agglomerations or clasts of what are interpreted to be magmatic or remobilised sulphide. There were no undeformed mafic intrusive rocks and the DHEM failed to identify any offhole conductors.
A magnetic pipe-like intrusive body 200 metres to the north of the conducive pipe being targeted is interpreted to be a feeder to the mafic units targeted with this phase of drilling (to the north). As such, additional ground-based exploration is now being considered to better define the South Pipe Conductor drill target.
The target model for the South Pipe is the high-grade EL Deposit in the Mining Centre. It is important to note that the high-grade nickel-copper-cobalt sulphide breccia intersected at depth (the EL Deeps discovery - 2011) could not be detected using DHEM from drill holes close by, despite displaying in-hole DHEM conductance.
Hole #23 is one of the three holes that have tested the area west of the FLC within defined high-conductance trends identified by the MobileMT. This hole was drilled in 2020 prior to the MobileMT survey and targeted a magnetic high in an area that included strong gravity and IP anomalism. Drilling intersected prospective altered gabbro and strong indications of magmatic sulphides up to 10% content (ASX announcement 3 September 2020).
Two off-hole DHEM conductors have been defined (Table 1, figures 1 and 2). The largest of these conductors is 84 metres in strike and is traced to at least 287 metres in depth extents. These conductors are on the southern margin of the MoibleMT conductive trend, striking in line with a high priority MobileMT target, north of hole #23, that has yet to be drill tested.
Hole #18 drilled in 2018 targeted a magnetic anomaly west of the Matrix Trend (Figure 3) (ASX announcement 13 March 2018). New DHEM completed on this hole has identified three off-hole conductors and one in-hole conductor (Table 1).
The in-hole conductor (18B) is small and equates to only 3% to 5% sulphide content in core, which returned a grade of about 0.2% nickel and 0.13% copper. This is high-nickel tenor material and suggests a grade range of from 4% to 7% nickel and 2% to 4% copper for 100% sulphide content (ASX announcement 13 March 2018).
Conductors 18A and 18C represent good magmatic nickel-copper sulfide targets. The use and effectiveness of electromagnetics (including DHEM) in this area is negatively affected by the strong conductance of anomaly 18D. Conductor 18D is coincident with a volcanogenic massive sulphide (VMS) xenolith caught up in the gabbro intrusion, mapped

About Corazon
Corazon Mining Limited (ASX: CZN) is an Australian resource company with projects in Australia and Canada.
In Canada, Corazon has consolidated the entire historical Lynn Lake Nickel Copper Cobalt Mining Centre (Lynn Lake) in the province of Manitoba. It is the first time Lynn Lake has been under the control of one company since mine closure in 1976. Lynn Lake presents Corazon with a major development opportunity that is becoming increasingly prospective due to recent increases in the value of both nickel and cobalt metals, and their expected strong demand outlooks associated with their core use in the emerging global electric vehicle industry.
In Australia, Corazon is developing the Mt Gilmore Cobalt Copper Gold Sulphide Project (Mt Gilmore) located in New South Wales, which hosts the Cobalt Ridge Deposit - a unique high-grade cobalt-dominant sulphide deposit. Mt Gilmore is a regionally substantive hydrothermal system with extensive cobalt, copper and gold anomalism. The Company has completed definition drilling at the Cobalt Ridge Deposit and is currently identifying new areas prospective for additional Cobalt Ridge lookalike deposits.
Both Lynn Lake and Mt Gilmore place Corazon in a strong position to take advantage of the growing demand for commodities critically required for the booming rechargeable battery sector.

The Lynn Lake project has been explored for more than 75 years and was mined for more than 24 years. There exists an enormous amount of historical data available to the company. This announcement only contains results for the current exploration program at Lynn Lake. Historical exploration results and mining data are referenced if considered material to this announcement. DHEM Geophysical Surveys This work program was completed and managed by Nova Scotia based Canadian geophysical consultancy Eastern Geophysics Limited and overseen on the Company’s behalf by Dr Larry Hulbert and Martin St-Pierre (P. Geophysicist). All data is captured digitally. Procedures are in place to guarantee data quality, which is verified by field personnel and subsequently forwarded to Eastern Geophysics and Corazon Mining Limited’s consultant geophysicist Martin St-Pierre for additional QA/QC. Eastern Geophysics has completed DHEM on several holes in the Fraser Lake area of the Lynn Lake Project. The surveys utilised standard Crone Pulse EM equipment with two loops designed (one off-set from hole) and surveyed for each drill hole. Survey Parameters Drill hole surveys are observed in X, Y, and Z components, using B field (fluxgate) probe. Downhole reading intervals of 10m or 5m in anomalous areas. Tx. Loops and general grid control utilized hand-held GPS. TX. Loops and drill hole collar locations positioned with DGPS. Step response calculations may be used if required.
