Corazon Mining Limited (ASX: CZN) (Corazon or Company) is pleased to provide an update on activities at its flagship project, the 100%-owned Lynn Lake Nickel-CopperCobalt Sulphide Project (Lynn Lake or Project) in the province of Manitoba, Canada.
Corazon’s ongoing focus is the pursuit of the potential redevelopment of Lynn Lake’s historical nickel sulphide Mining Centre towards production, and the targeted exploration for new nickel-copper-cobalt sulphide deposits within the Project area.
At the Mining Centre, the Company is assessing the potential to benefit from the extensive low-grade sulphide mineralisation surrounding known deposits and identifying relatively untested extensions to the current resources (within the upper levels of the mine surrounds).
Metallurgical testwork on lower grade material is currently underway and new 3D models of structure, rock type and geophysical surveys for the A-Plug Mining Centre (Figure 1) are being utilised to define potential areas for exploration and resource definition drilling.
Exploration drilling is ongoing at the Fraser Lake Complex (FLC) (Figure 1), testing geophysical targets (ASX announcement 11 April 2022). Encouraging nickel and copper sulphide mineralisation has been intersected at the Motriuk intrusion (ASX announcement 7 June 2022). The existence of visible pentlandite (nickel sulphide) in blebs and the potential for these sulphides to accumulate at depth, provide a compelling target for the drilling currently in progress.

Fraser Lake Complex Exploration Drilling
Exploration drilling at the Fraser Lake Complex is continuing, following early encouraging results from drilling at the Motriuk Ultramafic (ASX announcement 7 June 2022).
Progress of the drilling has been slow, with the drilling contractor needing to revert to one shift per day, due to the limited availability of personnel. This is an industry-wide issue due to both the effects of the Covid-19 pandemic and the seasonal demands for exploration personnel.
Currently, there is a 10-day scheduled break in drilling, which is due to recommence on the 22[nd] of July 2022. With an all-inclusive per-metre rate for this drilling program, Corazon bears no additional cost for drilling down-time or slow meterage.
In mid-June 2022, senior Company personnel traveled to site to review the progress of the drilling, including the sulphides intersected at Motriuk (ASX announcement 7 June 2022). While the amount of sulphide mineralisation reported was low (typically 1-5% of volume) and as such the expectations for the nickel content is also low, the existence

ASX Announcement | Lynn Lake – Project Update – 13 July 2022
==> picture [384 x 9] intentionally omitted <==
==> picture [125 x 29] intentionally omitted <==
of visible pentlandite is very encouraging. The Motriuk Complex historically has been considered nickel-deficient compared to the average for such ultramafic rock (pyroxenites and peridotites). It is assumed the nickel was extracted from the melt as sulphide (pentlandite) during the magma’s transportation to Motriuk, or in-situ.
The Motriuk Ultramafic body is “keel-like” in shape, with a base that has been defined by geophysics. The current drilling is targeting the base of this intrusion, which has a dense and magnetic geophysical signature.
Updates regarding this drilling will be provided in due course.
Mining Centre Exploration and Mining Studies
Corazon’s geological personnel are working with international mining consultants, Palaris, on incorporating all relevant historical data into 3D digital models that will facilitate the identification of areas for potential resource upside within the Mining Centre. This study is progressing according to plan, with results expected next month.
These new 3D models are precursors to new mining studies for Lynn Lake. These studies are expected to determine the most appropriate development pathway to deliver a robust, long-lived, economically viable mining operation, utilising modern mining and processing techniques.
Palaris have been engaged to undertake mining studies, which are focused on four separate disciplines: Geology, Geotechnical, Mining Strategy and Processing. The study program seeks to assess and maximise the synergies and interactions across all four disciplines to ensure optimal whole-of-project outcomes. The final deliverable of the mining studies will be a revised mining strategy for the entire mineralised area, focused on optimal production rates and low mining costs.
Metallurgical Testwork
New metallurgical testwork has commenced on the Lynn Lake mineralisation. Approximately 1,200 kilograms of core sample acquired from drilling in December 2021 from the EL Mine (Figure 1) is being used to:
-
Finalise flotation testwork;
-
Investigate pre-flotation ore-upgrade of low-grade material; and for
-
Initial work on the amenability of Lynn Lake mineralisation in the production of battery grade products for rechargeable lithium-ion batteries.
Two third-party suppliers of ore-sorting (upgrade) technology have been engaged to complete initial bench-scale testwork on low-grade material from the EL Deposit. Intervals of interest within the two metallurgical drill holes include:
| From | To | Interval | Ni% | Cu% | Co% | |
|---|---|---|---|---|---|---|
| EL-2201-01 | 10 | 77.6 | 67.6 | 0.61 | 0.30 | 0.019 |
| EL-2201-02 | 10 | 76.8 | 66.8 | 0.54 | 0.30 | 0.017 |
| Table 1– EL Deposit drilling (December 2021) – Mineralised intervals |
Some of this material sits outside the current resource for the EL Deposit and indicates good potential for additional resource tonnages. Ore-sorting testwork samples have been determined based on geology and grade. Three low-grade samples have been created (Table 2), disregarding sample intervals of plus 1% Ni, as it is envisaged they would constitute direct ROM feed.
Additional metallurgical testwork will be considered subsequent to the results of the ore-sorting studies.

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 hosts a large JORC nickel-copper-cobalt resource and 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 exploring the Miriam Nickel-Copper Sulphide Project (Miriam) in Western Australia and the Mt Gilmore CobaltCopper-Gold Sulphide Project (Mt Gilmore) in New South Wales.
Miriam is a highly prospective nickel sulphide exploration project, representing a strategic addition to Corazon’s portfolio of nickel sulphide assets.
Mt Gilmore is centered on a regionally substantive hydrothermal system with extensive copper, cobalt, silver and gold anomalism, including high-grade rock chip samples over a strike of more than twenty (20) kilometres. Mt Gilmore also hosts the Cobalt Ridge Deposit - a unique high-grade cobalt-dominant sulphide deposit.
The commodity mix of Corazon’s projects place it in a strong position to take advantage of the growing demand for metals critically required for the booming rechargeable battery sector.

Material information not included in the table above includes the “down hole length and interception depth”. This information has been provided in table form in the body of the announcement. Downhole survey data is not reported within and is not considered material to this report. Reported mineralised intervals may not be defined as “true widths”. |

| Data aggregation methods In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. |
No data aggregation has been reported in this announcement and no adjustment to primary assaying has been undertaken. For reporting significant intersections, all averaging over intervals is calculated on an individual interval weighted average basis. This report tables results of the interpreted mineralised zone intersected by the drilling. Results are focussed on the broad lower-grade interval. |
||||||
| Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. |
All averaging over intervals is calculated on an individual interval weighted average basis from the primary (initial) assay data. No bottom-cuts or top-cuts have been applied. |
