Extensive nickel and copper mineralisation in drilling at Lynn Lake Project
107m thick zone with visible nickel and copper sulphides intersected + adjacent downhole EM conductor identified
Corazon Mining Limited (ASX: CZN) (Corazon or Company) is pleased to provide an update on drilling at its 100%-owned Lynn Lake Nickel-Copper-Cobalt Sulphide Project (Lynn Lake or Project) in Manitoba, Canada.
Exploration underway at Lynn Lake is focused on the Fraser Lake Complex (FLC), a large metal rich mafic intrusive body, located approximately five kilometres from the historical Lynn Lake Mining Centre (Mining Centre) (Figure 1).
Corazon has drilled three holes to date in its current diamond core drilling program and is pleased to report it has intersected nickel and copper mineralisation.
Hole 045, drilled to a target depth of 618 metres, has intersected extensive magmatic mineralisation with visible nickel and copper sulphides (Figure 2) from surface - including a zone 107 metres thick, from 241 to 348 metres downhole. This intersection is typical of the low-grade mineralisation within the historical Lynn Lake Mining Centre.
This mineralisation has been geophysically linked to a dense-magnetic body approximately 200 metres to the south of hole 045. Corazon is currently drilling this target (at drill hole 046, Figures 3 and 4).
Downhole electromagnetics testing of hole 045 has identified a strong 'off-hole' conductor approximately 40 metres by 20 metres, starting from just 20 metres below surface. It is interpreted that this feature represents stronger concentration of the sulphide mineralisation intersected in hole 045 and is proposed for drill testing after the current hole 046.
Key Highlights
Drilling continuing at the Fraser Lake Complex, south of Lynn Lake Mining Centre
Targeting numerous untested pipe-like intrusive bodies (pipes) analogous to the massive sulphide deposits previously mined at Lynn Lake
Hole 045 has intersected a 107m-thick sequence of strong disseminated to net- textured and blebby sulphide mineralisation - possibly associated with a conductive body located nearby with downhole electromagnetics
Assays have been submitted and results will be released when available

Details of Drilling Completed
Corazon plans to test a minimum of four targets at the FLC, for a total of approximately 3,000 metres of core drilling in the current phase of drilling. About eight to ten priority targets were generated from recent geological surveys (ASX announcement 17 January 2022) and, pending drilling results, the current program may be extended to include these priority targets.
To date, an initial test of three targets has been completed for a total of 1,923 metres (Table 1, drillholes FLC-2022-041, 042 and 045).

Drill hole FLC-2022-045 has been completed, to a depth of 618 metres, targeting a large coincident gravity/magnetic anomaly within the Motriuk Complex (Figure 1). Motriuk forms part of the intrusive magmatic channel system, located west of the main FLC intrusion.
Hole 045 has intersected extensive magmatic sulphide mineralisation from surface, including visible nickel and copper sulphides (Figure 2). The best zone of mineralisation is 107 metres in thickness, from 241 to 348 metres downhole, and is similar to the low-grade mineralisation at the historical Lynn Lake Mining Centre. This includes disseminated, net- textured and aggregate blebby sulphides typically <5% of the rock mass and up to 20% over short intervals (Table 2).
The mineralisation intersected within hole 045 has been geophysically traced to a dense-magnetic body approximately 200 metres to the south (Figure 4). Drilling of the core of the anomaly has commenced with drill hole FLC-2022-046.

ASX Announcement | Lynn Lake Drilling Update - 7 June 2022
Downhole electromagnetics (DHEM) completed within hole 045 has identified an exciting nearby off-hole conductor (Figure 4), measuring approximately 40m by 20m, starting from only about 20 metres below surface. This conductor possibly represents a stronger concentration of the sulphides intersected by hole 045. Drilling of this anomaly (proposed
onlyhole FLC-2022-047) will be completed subsequent to drilling hole 046.
Drill holes FLC-2022-041and 042 (Figure 3) were paused approximately 200 metres from their proposed final depth. Variations in the lithologies intersected in drilling have not matched the interpretation of the aerial geophysics (gravity, magnetics and electromagnetics). As such, Corazon has taken a cautious approach, deciding to complete DHEM to assess the progress and positioning of the drill holes. DHEM is a geophysical method that is much more accurate for the definition of massive sulphides (compared to aerial methods) and is expected to refine the targeting methodology for these areas.
Wet weather and poor surface conditions are currently preventing access to these drill holes. DHEM will be completed useas a priority as soon as conditions improve.
The current drilling program is expected to extend past its planned completion date (the end of the current month). A ays will be progressively submitted, and results will be released when available.
Background to Drill Targets
The current drilling program has been designed to test discrete, geophysically-densepipe-like bodies (pipes) within the
FLC, which are analogous to the spatially related ultramafic intrusives and massive sulphide deposits within the Mining personalCentre, which were previously successfully mined over a period of 24 years.
Cor zon completed a detailed aerial gravity geophysical survey over the FLC in January 2022 that identified numerous de se, pipe-like bodies that have not been drill-tested (Figure 2) (ASX announcement 17 January 2022). These features are also present within the magnetic data and appear to come together to form a large body at depth within the centre of the FLC.
The geophysical characteristics of the FLC pipes are most similar to the EL Deposit within the Mining Centre. The EL Deposit is a vertical intrusive mafic pipe, about 300 metres in diameter, with an internal core of massive sulphide breccia and ultramafic rocks between 80 and 120 metres in diameter.
The EL Deposit was mined to only 200 metres below surface, producing approximately 1.9 million tonnes of ore at 2.4% nickel and 1.15% copper.
The potential for massive sulfide deposits to exist in close association with ultramafic lithologies within the extremely mineralised FLC forms the basis of the Company's current drilling program.
