Corazon Mining Limited (ASX: CZN) (Corazon or Company) is pleased to announce initial positive visual results from its current phase of drilling at the Lynn Lake Nickel-Copper-Cobalt Sulphide Project (Lynn Lake or Project) in Manitoba Province, Canada.
Drilling will test several high-priority targets including recently identified geophysical conductors. The targets are situated immediately west of the Fraser Lake Complex (FLC)/ Matrix Trend, within the Lynn Lake Project area (figures 3 and 4). The initial drilling program will test at least three targets and comprises approximately 1,600 metres of diamond core drilling, with follow-up work depending on results.
The first hole FLC2021-24 (#24) has now been completed, and the Company is pleased to report highly encouraging definitive visual evidence of significant sulphide mineralisation, including nickel and copper sulphides. The best sulphide mineralisation was intersected ontrend from the main geophysical conductor in the first target area (figures 1 and 3). This is a potentially significant discovery at Lynn Lake, opening up a new exploration front that includes multiple geophysical conductors for testing (ASX announcements 9 and 23 November 2020).
The magmatic sulphide appears of high quality (Figure 2). It is dominated by pyrrhotite, with chalcopyrite and pentlandite also observed. Assay results from the first hole are expected to be available next month and will provide confirmation of nickel-copper tenor and grade.
Drill hole #24 was completed to a depth of 485 metres. The hole started in (barren) sulphidic sediments and ended in sediments, drilling through approximately 320 metres of prospective gabbros and norites, typical of the host rocks within the Lynn Lake Mining Centre, eight kilometres to the north.

Hole #24 was planned to test a number of geophysical features. The intersection of strong sulphide mineralisation hosted by intrusive gabbro-norites and on-trend with a conductor body defined by the MobileMT geophysical survey, supports the effectiveness of the MobileMT method in the exploration for massive nickel sulphide at Lynn Lake.

Sulphide Mineralisation
The sulphide mineralisation intersected in hole #24 is consistent with the Lynn Lake style of mafic/ultramafic intrusive (igneous) magmatic sulphide systems, hosting sulphides varying in concentrations from massive to weakly disseminated, commonly decreasing in content away from the intrusive centre or structural control.
The Lynn Lake Mining Centre operated for 24 years, before closure in 1976, with an average grade of 1.02% nickel and 0.54% copper. Massive sulphide mineralisation (greater than 65% sulphide) typically graded at between 2% and 4% nickel.
The dominant sulphide is pyrrhotite (iron), with variable quantities of pentlandite (nickel) and chalcopyrite (copper). Although these minerals are visible, there is strong variability in the sulphide content throughout the hole and, as such, no estimation of the quantity of individual sulphide minerals are provided within.

In hole #24, sulphide mineralisation is widespread within the intrusive mafic units, predominantly disseminated in character, but also grading to localized blebby/globular and rare semi-massive to massive (typically less than 10 centimetres in width) concentrations.
The strongest sulphide mineralisation is described as 1.92 metres in length, averaging 15%-25% magmatic suphide, including 0.9 metres of semi-massive sulphide with up to 30% total sulphide content (Figure 2 and refer to Table 2 for description).
Current Work Program - Drilling is Ongoing
Drilling is currently underway on the second hole of the program, FLC2021-26 (#26), which is designed to test a strong conductor 250 metres west of the first hole #24. Hole #26 is the highest conductance target of the new targets situated to the west of the FLC/Matrix Trend (Figure 3).
Corazon plans to test the extensions of mineralisation in hole #24 with downhole EM. This is anticipated to define the in-hole conductance trend more accurately and refine planned follow-up drilling.
Site preparations for drilling at the high-priority South Pipe target (Figure 4) are expected to be completed this week, with drilling to be incorporated into the current program (proposed hole FLC2021-29).
The South Pipe conductive anomaly is the largest conductive target in the Fraser Lake area and the highest priority target.
Results from the drilling will be released as they become available. This will include, if appropriate, statements regarding definitive visual evidence of significant sulphide mineralisation.

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.
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.
