DRILLING INTERSECTS WIDE ZONES OF DISSEMINATED MINERALISATION AT LYNN LAKE PROJECT
-
1,415m, five hole drilling program completed at the Lynn Lake Project ( Lynn Lake ) in Canada
-
Three holes completed at the Fraser Lake Complex (FLC) intersected widespread sulphide mineralisation
-
Samples have been submitted for laboratory analysis - results are pending
-
Visual observation indicates the disseminated mineralisation is consistent with the outcomes of prior successful drilling at Lynn Lake
-
FLC is a large mineralised system – Corazon’s ongoing exploration continues to deliver encouraging results and strengthen the geological model and targeting processes for economic nickel-copper-cobalt sulphide deposits
-
JORC Resource upgrade underway for the Lynn Lake Mining Centre – Resource to be used in mining studies for assessment of a potential future mining operation
-
Exploration program also underway at the Mt Gilmore Cobalt-Copper-Gold Project in NSW - details of upcoming field work at both projects to be provided in near future
Corazon Mining Limited (ASX: CZN) ( Corazon or the Company ) is pleased to announce it has completed its latest phase of drilling at the Fraser Lake Complex ( FLC ), located just five kilometers south of its 100% owned Lynn Lake Nickel-Copper-Cobalt Mining Centre ( Lynn Lake ) in Canada.
Corazon has active exploration programs underway at both its Lynn Lake Project in Canada and the Mt Gilmore Cobalt-Copper-Gold Project in New South Wales, Australia.
Drilling at Lynn Lake comprised three holes at the FLC and two holes at targets closer to the Lynn Lake Mining Centre for a total of 1,415 metres (refer to Table 1 for details). This phase of drilling targeted large, untested geophysical anomalies identified in Corazon’s successful 2017 Field Season at Lynn Lake,
Corazon’s 2017 drilling resulted in the discovery of a significant, new magmatic nickel-coppercobalt sulphide system at the FLC, exhibiting similar characteristics to the nearby high-grade NiCu-Co Sulphide EL Mine Deposit, within the Lynn Lake Mining Centre.
The Company advises that significant and widespread disseminated to heavy net-textured sulphide mineralisation was intersected in this recent drilling from surface and throughout all holes within the FLC. These initial results from this phase of drilling are consistent with mineralisation intersected in the 2017 drilling program.
Samples from this drilling have been submitted for laboratory analysis and the Company will release results as they become available.
Drilling at the FLC continues to deliver positive results which strengthen Corazon’s geological model for the target, and belief that the FLC has the potential to host significant nickel-copper-

cobalt sulphide deposits. It is noted, though, that the feeder zone(s) for this mineralisation have not yet been identified. With this aim in mind, the results of the recent drilling will enable the Company to further refine its targeting and interpretation processes for on-going exploration.
The Company also advises that work has commenced for the re-estimation and up-grade of Resources within the Lynn Lake Mining Centre. These Resources will be used to complete mining studies for the re-establishment of mining at Lynn Lake. The price of nickel has risen strongly in the past 12 months and the forecast demand outlook is similarly positive, factors which add weight to the potential economic viability of mining at Lynn Lake.
In addition to the ongoing work at Lynn Lake Project, Corazon has an active exploration program underway at the Mt Gilmore Cobalt-Copper-Gold project in New South Wales, Australia. Details of upcoming fieldwork at both projects will be provided in due course.

Competent Persons Statement
The information in this report that relates to Exploration Results and Targets is based on information compiled by Mr. Brett Smith, B.Sc Hons (Geol), Member AusIMM, Member AIG and an employee of Corazon Mining Limited. Mr. Smith has sufficient experience that is relevant to the style of mineralization and type of deposit under consideration and to the activity that he is undertaking to qualify as a Competent Person as defined in the 2012 Edition of the “Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves”. Mr. Smith consents to the inclusion in the report of the matters based on this information in the form and context in which it appears.
Canadian geologist Dr. Larry Hulbert has been engaged by Corazon to manage the collation of past exploration information and the definition of new targets at Lynn Lake. Dr Hulbert has extensive knowledge of the Lynn Lake district and over 40 years’ experience in Ni-Cu-PGM exploration and research. Dr Hulbert is one of North America's foremost experts on magmatic sulphide deposits and would qualify as a Competent Person as defined in the 2012 Edition of the “Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves”.
Dr. Hulbert has authored numerous professional papers, was the recipient of the Barlow Medal from CIM in 1993, a Robinson Distinguished Lecturer for the Geological and Mineralogical Association of Canada for 2001-2002, and in 2003 received the Earth Sciences Sector Merit Award from Natural Resources Canada.
Forward Looking Statements
This announcement contains certain statements that may constitute “forward looking statement”. Such statements are only predictions and are subject to inherent risks and uncertainties, which could cause actual values, results, performance achievements to differ materially from those expressed, implied or projected in any forward looking statements.
Forward-looking statements are statements that are not historical facts. Words such as “expect(s)”, “feel(s)”, “believe(s)”, “will”, “may”, “anticipate(s)” and similar expressions are intended to identify forward-looking statements. These statements include, but are not limited to statements regarding future production, resources or reserves and exploration results. All such statements are subject to certain risks and uncertainties, many of which are difficult to predict and generally beyond the control of the Company, that could cause actual results to differ materially from those expressed in, or implied or projected by, the forward-looking information and statements. These risks and uncertainties include, but are not limited to: (i) those relating to the interpretation of drill results, the geology, grade and continuity of mineral deposits and conclusions of economic evaluations, (ii) risks relating to possible variations in reserves, grade, planned mining dilution and ore loss, or recovery rates and changes in project parameters as plans continue to be refined, (iii) the potential for delays in exploration or development activities or the completion of feasibility studies, (iv) risks related to commodity price and foreign exchange rate fluctuations, (v) risks related to failure to obtain adequate financing on a timely basis and on acceptable terms or delays in obtaining governmental approvals or in the completion of development or construction activities, and (vi) other risks and uncertainties related to the Company’s prospects, properties and business strategy. Our audience is cautioned not to place undue reliance on these forward-looking statements that speak only as of the date hereof, and we do not undertake any obligation to revise and disseminate forward-looking statements to reflect events or circumstances after the date hereof, or to reflect the occurrence of or non-occurrence of any events.
The Company believes that it has a reasonable basis for making the forward-looking Statements in the announcement based on the information contained in this and previous ASX announcements.
The Company is not aware of any new information or data that materially affects the information included in this ASX release, and the Company confirms that, to the best of its knowledge, all material assumptions and technical parameters underpinning the exploration results in this release continue to apply and have not materially changed.
