ADDITIONAL HIGH-GRADE NICKEL DRILLING RESULTS AT LYNN LAKE FURTHER ENHANCES RESOURCE EXPANSION POTENTIAL
-
Further excellent assay results have been returned from the recently completed drill program at the Lynn Lake Nickel-Copper-Cobalt Sulphide Project in Canada
-
Mineralised high-grade nickel intervals include:
-
“A Orebody”
-
37.8 m @ 1.68%Ni, 0.67%Cu, 0.050%Co from 10 metres; including
- 22.6m @ 2.30%Ni, 0.82%Cu, 0.068%Co from 24.4 metres
-
“E Orebody”
-
4.5 metres @ 1.17%Ni, 0.22%Cu, 0.029%Co from 25 metres
-
4.1 metres @ 2.09%Ni, 0.57%Cu, 0.073%Co from 26.9 metres
-
These near-surface high-grade intersections strengthen the potential to add to Lynn Lake’s significant nickel-sulphide resource base
-
Higher-grade intervals are typically supported by broad, anomalous zones of mineralisation
-
All priority assays have been returned – plans for further drilling at the A Orebody and E Orebody and other targets are underway, as are development/ metallurgical studies
Corazon Mining Limited (ASX: CZN) (Corazon or Company) is pleased to announce additional assay results from its latest phase of drilling at its 100% owned Lynn Lake Nickel-Copper-Cobalt Sulphide Project (Lynn Lake or Project) in Manitoba, Canada.
Assay results have now been returned for all priority samples from the Company’s drilling program completed in December 2019. Multiple zones of broad, near-surface high-grade mineralisation were intersected in areas surrounding previously mined deposits within the Lynn Lake Mining Centre (Mining Centre), significantly increasing the potential to expand the Project’s already substantial existing resource base.
Drilling targeted two historical deposits - the A Orebody and E Orebody (Figure 1) – with seven holes for approximately 1,122 metres of diamond core drilling completed (Tables 2 and 3). Both the A Orebody and E Orebody areas have potential extensions to known mineralisation that have not been historically tested with drilling. These areas provide significant resource expansion potential and will be the subject of ongoing targeted exploration and drilling.
Additionally, there are multiple other areas within the Mining Centre, also yet to be drill tested, that may also have the potential for near surface mineralisation surrounding historical underground mining operations.

Managing Director, Mr Brett Smith stated, “Historical mining at Lynn Lake focused largely on underground operations and the lack of near-surface exploration around the previously mined deposits has provided a substantial opportunity for Corazon to expand what is already a significant nickel sulphide resource base.
Our targeted drilling was designed to identify haloes of disseminated mineralisation around the mined deposits, and the results have been highly successful with the exceptional grades returned significantly exceeding expectations. In addition, the results have validated our targeting processes and paves the way for our ongoing, targeted exploration and drilling at Lynn Lake. “

DRILL PROGRAM SUMMARY
The Company’s recent exploration at Lynn Lake focused on defining additional areas of mineralisation with the potential to add to the Project’s significant existing resource base. Priority targets for the drilling program at Lynn Lake included:
-
near-surface mineralisation;
-
areas on-trend from historical mines; and
-
areas adjacent to existing resources.
Corazon’s recent mining studies at Lynn Lake predominantly centred on nickel deposits at depths of more than 400 metres below surface. This work has highlighted the potential to define additional resources closer to the surface and adjacent to Lynn Lake’s historically mined areas. The initial testing of these areas was the focus for the recent drilling program.

A total of seven holes were completed for approximately 1,122 metres of diamond core drilling (Table 2 and 3), mainly targeting the A Orebody and E Orebody areas (Figure 1 and 5). Several other near surface deposits within the large Mining Centre are yet to be considered for drill testing.
The Lynn Lake style of mineralisation is typical 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.
This latest phase of drilling tested near surface expressions of mined areas that operated continuously for 24 years at an average grade of 1.02% nickel and 0.54% copper.
Highlight Results

-
37.8 metres @ 1.68%Ni, 0.67%Cu, 0.050%Co from 10 metres; including
- 22.6 metres @ 2.30%Ni, 0.82%Cu, 0.068%Co from 24.4 metres

A Orebody
Holes LL2019-01, LL2019-02 and LL2019-03 tested areas around the A Orebody, historically covered with infrastructure from the “A-Shaft” and processing plant area within the Lynn Lake Mining Centre (Figures 1, 2 and 5)). The A Orebody was mined underground between 1953 and 1965, producing 4.8 million tonnes at 1.07% nickel and 0.55% copper (cobalt not reported). While the massive suphide crown-pillar was mined to surface, it was expected that good mineralisation existed where historical infrastructure restricted surface mining.
The A Orebody is described as sulphide lenses within a subcircular, subvertical, mafic to ultramafic igneous intrusive pipe. The area being targeted with drilling at the A Orebody is approximately 80 metres by 220 metres, surrounding previously mined high-grade massive sulphide (stoped to surface and backfilled). The mined massive sulphide mineralisation at the A Orebody is described as “pipelike” with dimensions of approximately 40 metres by 120 metres.
Hole LL2019-02 intersected a high-grade interval of 22.6 metres @ 2.30%Ni, 0.82%Cu, 0.07%Co. This interval was within a broader zone of mineralisation including 37.8 metres @ 1.68%Ni, 0.67%Cu, 0.05%Co, from just 10 metres down hole. The area being tested is open to the south towards where the A Shaft and the “Discovery Outcrop” (outcropping nickel and copper sulphide mineralisation) is situated (Figure 2).
Hole LL2019-01 returned good marginal-grade material with 7 metres @ 0.62%Ni, 0.37%Cu, 0.02%Co, west of the main zone being targeted by LL2019-02. This hole was terminated on hitting the backfilled crown-pillar stope at 34.1 metres.
Hole LL2019-03 intersected good zones of marginal-grade material to the north of the crown-pillar stope, including three zones with intervals of four to nine metres downhole and grades of between 0.50% and 0.65% nickel. Mineralisation is this area is expected to be patchy in character, with grades increasing closer to the stopped area.

E Orebody
Holes LL2019-04 and LL2019-05 tested areas around the E Orebody (Figure 3).
The E Orebody is described as structurally controlled late intrusive sulphide lenses within a gabbro host. The E Orebody was mined underground between 1957 and 1963, with production estimates of about 930,000 tonnes at 1.06% nickel and 0.48% copper (cobalt not reported). The footprint of the underground stope is interpreted to cover an area of approximately 15 metres by 100 metres. This stope does not come to surface.
This recent drilling has targeted the margins of the stope area, with the northern and southern extensions of the mineralisation previously mined, yet to be tested.

Hole LL2019-05 tested the footwall mineralisation west of the stope, returning 4.1m @ 2.09%Ni, 0.57%Cu, 0.07%Co. This hole was terminated when it intersected stope fill at 36 metres.
Drilling supports the drilling target area for the E Orebody of approximately 30 metres by 300 metres. When this mine was in operation, the northern extensions of the E Orebody trended beneath the mine camp, and as such, has not been drilled.

Farley East
Holes LL2019-06 and LL2019-06A targeted an atypical geophysical feature east of the Farley Shaft in the central area of the A Plug (Figure 5). The geophysical feature is located in a similar setting to the D, G and Golf deposits, east of the main mine trend.
Hole LL2019-06 was abandoned due to poor drilling conditions. Hole LL2019-06A was the re-drill of hole LL2019-06. Selected samples from these holes have been submitted for analysis.
The geophysical anomaly has been attributed to glacial sands occupying a fault zone within the gabbro intrusion. Drilling intersected sands at approximately 280m metres downhole (in LL2019-06). It is possible that hydrostatic pressure from pre-existing glaciers forced fluidised sand material down the fault zone.

NEXT STEPS FOR LYNN LAKE
Near Mine Exploration - Resource Definition
The recent drilling program established the potential for the areas surrounding previously mined deposits to deliver near-surface tonnages. The Project currently hosts a significant resource and the potential for additional “easy start-up” tonnages would be enormously beneficial for any new mining operation at Lynn Lake. Accordingly, defining such tonnages is a key priority for the Company as it moves towards feasibility work.
There are also several other areas in the Mining Centre with the potential for near surface mineralisation surrounding historical underground mining operations. The Company is currently working on new drilling programs to test these areas, in addition to further work at the A Orebody and E Orebody prospects. Considering the amount of historical cultural features in the old mine area, drilling of these targets is best suited to times when there is no snow cover.
Regional Exploration
The recent targeting work within the Mining Centre has refined targeting methodologies, particularly with respect to the processing and interpretation of geophysical datasets. These new processes can easily and quickly be applied regionally in the exploration for new deposits.
A priority target area is the Fraser Lake Complex (FLC) (Figure 5) where drilling by Corazon has discovered a large magmatic sulphide system that is an analogy to the Lynn Lake deposits. The recent drilling in the Mining Centre, adjacent to mined massive sulphide deposits, reinforces the belief that the style and intensity of mineralisation intersected is no different to what we have drilled at FLC. The best results returned to date from FLC drilling include:
-
22.6 metres @ 0.70% Ni & 0.35% Cu from 258m (hole #14)
-
27 metres @ 0.37% Ni & 0.16% Cu from 30m (hole #16)
Exploration work at FLC is well underway and is expected to identify priority drill targets for consideration in the near term.

Mining and Mineral Processing Studies
Studies currently in progress for Lynn Lake have identified areas where it is believed processes can be improved and costs reduced.
Historically, Lynn Lake was a large-tonnage low-cost mining operation. The current mining studies are looking to reduce mining and capital development costs for a potential underground operation via the implication of modern mining practices and new technology.
Recent metallurgical testwork has delivered exceptional results and there is a strong belief that further improvements can be made. Priority focus for this work will include the scoping and testwork for:

ABOUT CORAZON
Corazon Mining Limited 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 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 - one which is becoming increasingly prospective as a result of 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 (EV) industry.
In Australia, Corazon has recently increased its interest in the Mt Gilmore Cobalt Copper Gold Sulphide Project located in New South Wales, which hosts the Cobalt Ridge Deposit, a unique highgrade cobalt-dominant sulphide deposit.
Mt Gilmore is a recently recognised, regionally substantive hydrothermal system with extensive cobalt, copper and gold anomalism. The Company has recently 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.
