CORAZON EXPANDS LYNN LAKE PROJECT AREA
NEW LARGE CONDUCTOR TARGET DEFINED
-
Corazon has strategically expanded the Lynn Lake Project in Manitoba, Canada
-
Expanded tenure covers a recently identified large geophysical conductor – securing a new priority target for upcoming drilling
-
The target is substantial, with two sub-vertical pipe-like bodies – open at depth – known as the South Pipe Target
-
The South Pipe target model is similar to Lynn Lake’s high-grade EL Mine (mined 1.9Mt @ 2.4% Ni and 1.15%Cu)
-
Detailed planning is underway for drilling works scheduled to commence by year-end, subject to Covid-19 movement restrictions in Canada
Corazon Mining Limited (ASX: CZN) (Corazon or Company) is pleased to announce the acquisition of new ground at the Lynn Lake Nickel-Copper-Cobalt Sulphide Project (Lynn Lake or Project) in Manitoba Province, Canada, within which is located a substantial new geophysical anomaly.
The Company recently completed an aerial MobileMT geophysical survey at Lynn Lake (ASX announcements 3 September, 12 October and 9 November 2020) that identified multiple new anomalies indicative of nickel-copper-cobalt sulphide mineralisation.
The most substantial and highest priority geophysical anomaly defined by the MobileMT survey was located on vacant tenure outside of Corazon’s Lynn Lake project area, south and immediately adjacent to the prospective Fraser Lake Complex (FLC) (Figure 1).
This new anomaly includes two large magnetic pipe-like bodies, one of which is conductive, possibly indicative of a deep-seated intrusive pathway that appears linked to known nickelcopper-cobalt sulphide mineralisation within the FLC. This conductive anomaly is now a priority drill target in Corazon’s exploration for massive sulphide mineralisation at Lynn Lake.
Chairman Mr Terry Streeter stated; “We identified this feature almost immediately in the new geophysical data, more than six or seven weeks ago. Since then, the main priority has been to secure tenure over the anomaly.
So far, these targets are the only pipe-like bodies defined in the Fraser Lake area, an area that exhibits widespread sulphide mineralisation. This is what we’ve been chasing. Importantly, they represent a critical ingredient to understanding the geological model at Fraser Lake and are potentially ‘up-stream’, closer to the source, from gabbros polluted with nickel-copper-cobalt mineralisation.”

Exploration Plans
Corazon is in the process of organising a northern winter drilling program over the recently defined priority targets at Lynn Lake. The Company is working towards drilling as soon as practicable, subject to Covid-19-imposed movement restrictions in Canada. The first stage of the drilling program will be the preparation of access tracks and drill sites. This work will be carried out as soon as possible (taking advantage of any freezing conditions), ahead of the commencement of drilling, which is currently anticipated early in the New Year.

The South Pipe Target
The newly defined South Pipe magnetic anomaly includes two parallel pipe-like bodies approximately 150 meters apart; they are a dominant geophysical feature in the area west of the FLC. The southern body is conductive from about 100 metres below surface, to at least 850 metres. The northern pipe has no conductivity but is a strongly magnetic body with a geophysical signature very similar to areas within the Motruiuk Ultramafic Complex (peridotite) further to the north (Figure 1).
These two features are the first pipe-like bodies identified at the FLC and importantly provide an exploration target similar to the high-grade EL Deposit (mined 1.9Mt @ 2.4% Ni and 1.15%Cu to a depth of ~250 metres below surface) within the Lynn Lake Mining Centre.
The shape of the southern conductive body is mirrored by the northern strongly magnetic, body (together being the South Pipe). The spatial association of ultramafic (magnetic) bodies with massive sulphide deposits is noted in the main Lynn Lake Mining Centre, approximately nine kilometers to the northeast (Figure 1).

Drill Targets and the New Architecture for the Fraser Lake Complex Area
The new conductors identified from the results of the MobileMT geophysical survey are variable in form and the ‘conductors of interest’ have been defined and ranked on the basis of their intensity and coincidental anomalism with other geophysical characteristics (such as magnetics, gravity and IP).
The detailed definition of proposed drilling and the priority of targets is ongoing.
The greater Fraser Lake Complex target area has been expanded to encompass a number of intrusive mafic/ultramafic bodies, including; the main body of the FLC, the Southeast Lobe, the Motruiuk Ultramafic Complex, the South Pipe and areas that interconnect these bodies (Figure 1). This intrusive complex is more than twice the size of the intrusive host for the historical Lynn Lake Mining Centre.

ASX ANNOUNCEMENT 23 NOVEMBER 2020
----- End of picture text -----
Exploration has identified extensive magmatic iron-nickel-copper-cobalt sulphide mineralisation within the main body of the FLC, and particularly within the Matrix Trend (IP chargeability anomaly). This mineralisation has been attributed to multiple pulses of sulphide contaminated magma, occurring late in the intrusive history, flowing into the FLC from the west, along the Matrix Trend (Figures 2 and 3).
Gravity geophysical data identifies deep-seated north-northwest – south-southeast trending structures immediately to the west of the FLC main body, which geophysically domains the predominantly resistive FLC from the conductive environment to the west (which hosts the Motruiuk and South Pipe intrusions). This western domain has experienced limited exploration, has never been drilled and is now (subsequent to the MobileMT survey) believed to be a much more prospective environment for magmatic sulphide deposits.
The area west of the FLC portrays a complex interconnection of mafic and ultramafic intrusive bodies, underlain by deep crustal-tapping structures. The magnetic South Pipe is traced to the full depth extents of the geophysical processes and thus is believed to be a major pathway for magma into this area.
The shallow depth extents of the Motruiuk Ultramafic Complex (~500 or 600 metres below surface) and the gravity highs (interpreted as mafic intrusive lithologies) to the west of the Matrix Trend supports a flow of magma from the south to the north into the Motruiuk Complex, and possibly northeast into the Matrix Trend (juxtaposing the older FLC).
Conductive geophysical anomalies located along this interpreted magma channel-way provide exploration targets for massive sulphide mineralisation. Several conductors are located to the west of the Matrix Trend (ASX announcement 9 November 2020) and to the south towards the South Pipe conductive body (Figures 2 and 3).
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 highgrade 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.

| airborne audio-frequency magnetics technology. The system provides a | ||
| range of three-dimensional products that appear to be beneficial in | ||
| distinguishing magmatic nickel-copper sulphides conductors from other | ||
| conductive bodies. The MobileMT survey was carried out by Toronto | ||
| based Canadian geophysical consultancy, Expert Geophysics Limited | ||
| (EGL). | ||
| EGL completed quality control of the data, as well as preliminary data | ||
| processing, in the field, producing selected preliminary maps on | ||
| completion of the flying operations. Final data processing and | ||
| presentation of digital data performed at EGL’s offices in Toronto, Canada. | ||
| This was approximately a six week process, post completion of the survey. | ||
| Subsequent manipulation and presentation of the data supplied by EGL | ||
| was undertaken using GeoSoft (software) by Canadian geologist Dr Larry | ||
| Hulbert, who has been engaged by Corazon as an expert in magmatic | ||
| nickel suphide deposits. | ||
| The survey area covered about 50 km2for approximately 430 line-km, | ||
| taking just under 2 days to complete data capture. | ||
| The survey was performed using an AStar 350 B2 helicopter, with EGL | ||
| providing all necessary instrumentation for installation on the helicopter, | ||
| as well as base stations and field workstations(dataprocessingsystem) |

| for quality control and processing of the airborne data in the field. The | ||
| nominal flight altitude of the helicopter was between 140 and 150 m above | ||
| the terrain, with nominal terrain clearance of the MobileMT bird of between | ||
| 50 and 60 m. | ||
| The primary tools of the survey were an airborne MobileMT (Mobile | ||
| MagnetoTellurics) system which includes as a separate sensor a high- | ||
| sensitivity optically-pumped airborne magnetometer. | ||
| Electromagnetic data was digitized and recorded at 73,728 Hz and | ||
| processed two (2) times every second in time, resulting in electromagnetic | ||
| data sampled at approximately every 11 meters along each flight line. | ||
| Airborne magnetics data was recorded at 10 Hz, resulting in magnetic data | ||
| sampled at approximately every 2.2 meters along each flight line. | ||
| Navigation was accomplished by GPS with an absolute positional | ||
| accuracy of 2.5 meters or better. GPS navigation data was recorded and | ||
| processed at 10 Hz, resulting in GPS data every 2.2 meters along each | ||
| flight line. | ||
| Airborne magnetics was collected simultaneously with the airborne | ||
| electromagnetic data. | ||
| AIRBORNE SURVEY INSTRUMENTATION | ||
| The airborne survey system comprised the following instrumentation: | ||
| MobileMT (Mobile MagnetoTellurics) towed-bird with the 97 m |
||
| long tow cable | ||
| Geometrics G822A or Scintrex CB-3 Cesium Magnetometer, |
||
| installed in a separate towedbird, sensitivity of 0.001nT/10 Hz | ||
