Corazon Mining Ltd (ASX:CZN) has intersected extensive nickel and copper mineralisation in diamond drilling at its 100%-owned Lynn Lake Nickel-Copper-Cobalt Sulphide Project in Manitoba, Canada.
Three holes have been drilled to date in the program with hole 045, which was drilled to a target depth of 618 metres, intersecting extensive magmatic mineralisation with visible nickel and copper sulphides from surface - including a zone 107 metres thick, from 241 metres downhole.
Typical of Lynn Lake mineralisation
This intersection provides particular encouragement to Corazon as it is typical of the low-grade mineralisation within the historical Lynn Lake Mining Centre.
Mineralisation in this hole has been geophysically linked to a dense-magnetic body approximately 200 metres to the south and the company is drilling this target with hole 046.
Strong off-hole conductor
Testing of hole 045 with downhole electromagnetics identified a strong off-hole conductor around 40 metres by 20 metres, starting from just 20 metres below surface.
Corazon interprets that this feature represents stronger concentration of the sulphide mineralisation intersected in hole 045 and proposes to drill test this after hole 046.

Drilling continues
Drilling is continuing at the Fraser Lake Complex (FLC), south of the Lynn Lake Mining Centre, targeting numerous untested pipe-like intrusive bodies analogous to the massive sulphide deposits previously mined at Lynn Lake.
The FLC is a large metal-rich mafic intrusive body about five kilometres from the historical Lynn Lake Mining Centre.
Corazon plans to test a minimum of four targets at the FLC, for a total of around 3,000 metres of core drilling in the current phase of drilling.
About eight to 10 priority targets were generated from recent geological surveys 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.
Hole 045 stands out
The 107-metre intersection in hole 045 is a 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.
Drill holes FLC-2022-041 and 042 were paused about 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.
Wet weather and poor surface conditions are preventing access to these drill holes and DHEM will be completed as a priority as soon as conditions improve.
As a result, the current drilling program is expected to extend past its planned completion date at the end of this month.
The potential for massive sulphide deposits to exist in close association with ultramafic lithologies within the extremely mineralised FLC forms the basis of the company’s current drilling program.
