Obvious Exploration Upside
-
Highest grade deposit at Lynn Lake
-
Relatively shallow - only mined to 210m in a district with mining depths up to +1,100 metres
Near Surface Mineralisation

Upcoming Milestones:
-
How big is it?
-
Drilling underway, multiple holes
-
Drilling to continue during 2012
-
Recent drilling results have reshaped the deposit’s prospectivity
-
Priority target – high-grade potential at depth
-
Already underway
-
Analysis of the prospective economics of the project
-
Ongoing drilling program to define the new resource.
-
Expected by mid 2012
Other key timing considerations:
Exercise of option for 100% equity in Lynn Lake Project to be conducted by October 2012
Corazon is well funded to delineate the resource
Despite the cold conditions at Lynn Lake, drilling is conducted all year round

Poly-Metallic Mineralisation – Nickel, Copper & Cobalt
The EL Deposit is predominantly a nickel deposit, with significant copper and cobalt metal credits Lynn Lake has a long history of mining and processing, with historical recoveries reported as 85% for nickel, 93% for copper and 80% for cobalt
Recent drill results are well above the historic “run of mine” grades for the district

Mineral Resource
The EL Mine was one of the highest grade nickel mines in the district, having operated between 1954 and 1962 and produced 1.9Mt @ 2.5% nickel and 1.15% copper to a mined depth of only 210 metres. Whilst the defined boundary of the mineralised host unit is well established, drilling in areas of the resource has not been of sufficient density to accurately define the distribution of high-grade sulphide mineralisation. For this reason, the influence of the high grade material within the resource has been restricted and consequently the resource is categorised as inferred. This resource provides a very good base from which to focus on-going exploration, and it is the Company’s opinion that it is conservative in terms of the full potential of the deposit and that additional drilling will provide a more accurate model particularly for the distribution of high-grade mineralisation.
Mineral Resources have been estimated using standard accepted industry practices. All Resources have been estimated via Block Ordinary Kriging using 2m composite samples. No top cuts have been applied which was considered appropriate for the nature and style of the mineralization. Directional Variography was modeled for all zones based on 2m composites. Geological and mineralization modeling has been achieved by 3D modeling of the inner and outer core of the intrusive mafic/ultramafic plug and the mined voids. A Block model was developed for the deposit incorporating a suitable parent and sub block dimension to allow adequate volume resolution of modeled geology and mineralization. Grade interpolation (via Block Ordinary Kriging) was then undertaken using a multiple estimation pass strategy.
Mineral Resources are classified on a basis of drill-hole spacing, geological continuity and predictability, sampling, analytical, spatial and density QAQC criteria. Where quoted, Mineral Resource and Ore Reserve tonnes, pounds or ounces are rounded to appropriate levels of precision.
Corazon have yet to complete mining studies or metallurgical/processing analysis on the EL Mine mineralisation. However, Lynn Lake is an historical nickel, copper and cobalt mining camp which operated for more than 20 years. Reported historical mine base cut-off grades were between 0.5% and 0.7% nickel. Metal recoveries reported were approximately 85% for nickel, 93% for copper and 80% for cobalt. Past mining utilized very simple open stope with sublevel mining methods. The historical EL Mine main stope is up to 100 metres in diameter, plus 200 metres in depth, and provides a large tonnage - low cost mining opportunity.

Mineral Resource (continued)
Assay results are obtained from ALS Mineral Services in Thunder Bay, Ontario, Canada. Samples are prepared using single stage pulverization of the entire sample. Base metal assays are obtained by 4 Acid digestion using ICP with either Atomic emission spectrometry (AES) or atomic absorption spectrometry (AAS) analysis techniques.
Full analytical quality assurance - quality control (QAQC) is achieved using a suite of certified standards, laboratory standards, laboratory duplicates, blanks and grind size analysis. Assays quoted in announcements may be of a preliminary nature.
Assays from Corazon drilling and re-assayed historic drill-holes used in the Mineral Resource have undergone full QA/QC whereas assays from the 2007-2008 drilling by Western Areas did not have field standards used. The spatial location of samples from surface holes is derived from a combination of 3D differential GPS collar survey pickups and Reflex Maxibore® II downhole surveys. Historic underground hole included in the resource have not been surveyed by modern methods collars were digitized and converted from historic level plans.
Exploration Target
This Exploration Target is conceptual in nature, there has been insufficient exploration (namely drilling of verifiable quality) to define a mineral resource and it is uncertain if further exploration will result in the determination of a mineral resource.
The Exploration Target has been estimated to a depth of 1,200 metres below surface. It follows the discovery of a high-grade nickel sulphide breccia at depth below the historic EL Mine, as well as the recognition in historical drilling of a substantial amount of near surface low-grade mineralisation.
The basis for this target for the EL Deposit includes:-
-
Historical mining at the deposit to a depth of 210 metres below surface
-
Historical mine development to at least 270 metres below surface
-
Underground exploration drilling, sampling and mapping to a depth of approximately 600 metres below surface
-
The regional mining and development depth for the Lynn Lake camp is approximately 1,200 metres
-
There has been approximately 72,300 metres of historical surface and underground drilling complete
-
At the date of definition of the Exploration Target, Corazon Mining Limited had completed in excess of 10,700 metres of surface drilling
-
Good continuity and predictability of geology down-plunge
-
Geological evidence for a deep-seated, explosive mineralising event.
Past exploration and mining records for the EL Mine are extensive and reflects high standards of work.
The zones defined in the Exploration Target include the Upper, Mid and Lower Zones. The Upper Zone includes lower grade material that has the potential to be exploited from lower cost mining methods such as open pit mining. This zone extends to 200 metres below surface. The Mid Zone is the area between 200 and 800 metres below surface, and covers an area defined predominantly by the current Inferred Resource (reported at a 0.6% Ni equivalent[2] bottom cut-off grade). The Lower Zone extends from 800 metres to 1,200 metres below surface, the latter being the maximum depth at which historical underground development was conducted.
