Cobalt Intercept calculation parameters: Greater than or equal to 0.3m down hole thickness, greater than or equal to 0.05% Co, greater than or equal to 0.05% Co cut-off and less than or equal to 3m internal dilution. Gold values at lower detection limit <0.01ppm are attributed a value of 0.005ppm for interval calculations.
Copper equivalents: The composited value of the cobalt-copper-gold mineralisation is presented as percentage copper equivalents (CuEq%). These metals have been historically extracted from small scale mining at Mt Gilmore and it is the Company’s belief that the cobalt, copper and gold is recoverable. Metallurgical test work currently underway is expected to underpin these assumptions. CuEq% = Cu%+(Co%5.89)+(Au_ppm0.679).

RC and core drilling assay results have validated the Company’s assessment of Cobalt Ridge as a unique, high-grade cobalt-dominant deposit with the potential to deliver valuable, discrete high-grade zones of cobalt, within broader moderate grade mineralisation.
The main cobalt lode has been drilled over a strike of about 200 metres, to a depth of 140 metres below surface (Figures 1 and 2). The mineralisation is open to the west, where it is coincident with soil geochemical anomalism and small-scale historical workings targeting copper mineralisation.
The main cobalt lode mineralisation is typically about 16 metres in down-hole width (~8 metres true width), with intersections up to 37 metres down-hole. Average cobalt grades for these intervals within the drilling completed by Corazon are between 0.23% and 0.65% cobalt. Multiple higher-grade zones of up to 1.48% cobalt exist, at between one and seven metres down hole widths. Best individual one metre assay from this drilling is 2.79% cobalt.
Full drill results are presented in Table 2, with additional details pertaining to drilling and assaying are available in Table 3.
Importance of Cobalt
Cobalt is a metal of growing strategic importance due to its requirement for use in lithium-ion batteries and the emerging rechargeable battery sector. At current cobalt metal prices of around US$30,000 per tonne, the grades intersected in the drilling at Cobalt Ridge represent potentially significant in-ground value for both the broad zones and discreet high grade zones of cobalt mineralisation. Historic mining for cobalt, copper, gold and silver within the project area supports the opportunity for the metallurgical extraction of these metals. Metallurgical performance test work on RC drill chips is currently underway, with results expected Q1, 2017.
Background to Mr Gilmore drill program
Corazon’s maiden drill program at Mt Gilmore has been designed to confirm the continuity, position and extent of the cobalt-copper-gold mineralisation within the Cobalt Ridge prospect area, which has been identified by previous drilling. Corazon’s drilling has validated historical mining and exploration results and has confirmed the presence of multiple zones of sulphide mineralisation over a strike length of at least 300 metres. The mineralisation remains open along strike and at depth.
Between October and December 2016 Corazon completed 18 RC holes at Cobalt Ridge, three of these holes were extended with core tails. In total 2,070 metres of RC and 261.10 metres of core was completed.
Full details of this program are presented in Table 3.

Cobalt Ridge – Potential Upside
Geological interpretation of the drill core and RC assay results has resulted in a fuller understanding of the mineralisation at Cobalt Ridge. As evidenced in the diamond core (Figure 3), the mineralised system displays intense pervasive alteration and sulphide filled tourmaline brecciation indicative of a larger cobalt-copper-gold system. This alteration is observed on surface at Cobalt Ridge and other prospects within the greater Mt Gilmore region.
Three priority target areas have been defined at Cobalt Ridge. None of these targets have been tested with modern exploration and it is proposed that surface geochemistry and geophysics will provide a good first-pass test.
Cobalt Ridge West – The best result from drilling by Corazon at Cobalt Ridge is the western-most hole, MGRC002. This mineralisation plunges to the west-northwest, coincident with the intersection of structures and lithologies. Additional (undrilled) structures have been identified at surface, which have the potential to generate high-grade mineralisation.
The target is supported by anomalous soil geochemistry (Figure 2) and abundant sub-cropping quartztourmaline-limonite breccia (Cobalt Ridge host rock).
Flintoff’s – This target sits immediately to the north of Cobalt Ridge and is centred on late 1800’s copper workings. These workings exhibit the same trend and host material as at Cobalt Ridge, but are substantially larger.
The edge of the Cobalt Ridge soil sampling survey just touches on this trend, returning strong anomalism (Figure 2).
Cobalt Ridge East – The target is situated at the intersection of the Cobalt Ridge and Flintoff’s trends, under the cover of thin sediments.

Mt Gilmore Project Overview
The Mt Gilmore Project (“Project”) is located 35 kilometres from the major centre of Grafton in northeastern New South Wales. Corazon owns a 51% interest in Mt Gilmore and has an exclusive right to earn up to an 80% interest in the Project.
The Project is located in the New England Orogen, a significant mineral province in Eastern Australia with a gold endowment of more the 35M ounces and the potential to host large copper-gold systems.
This region hosts deposits such as the Mount Morgan Cu-Au Mine (+50Mt @ 5.9 g/t Au and 0.7% Cu) and Mt Rawdon Gold Mine (50Mt @ 0.71 g/t Au).

ANNOUNCEMENT
16 January 2017
==> picture [197 x 84] intentionally omitted <==
Within the Project, a prospective 18 kilometre trend (the Mt Gilmore Trend) has been identified which includes:
-
More than 25 historic copper, gold, cobalt and iron workings, including significant shafts, adits and drives with high-grade copper and gold mineralisation (rock chips up to grades of 26.8%Cu and 9.2 g/t Au); and
-
Five large scale Cu-Au targets defined to date.
Although mapping indicates extensive hydrothermal alteration and copper-gold mineralisation at surface, very little modern exploration has been undertaken. Aside from small-scale historic coppergold and iron mines, previous exploration has predominantly been restricted to general prospecting/ mapping, rock-chip/ grab sampling, with drilling completed at only one of the targets (the Pulganbar – Cobalt Ridge area).
The Cobalt Ridge Prospect
The Cobalt Ridge Prospect is a small part of the greater Mt Gilmore Copper-Cobalt-Gold Project. It represents an advanced cobalt play with shallow drilled defined Co-Cu-Au lodes that remain open along strike and at depth.
The high-grade nature of this cobalt mineralisation is published in historical records from shallow mining (maximum shaft depth 36.5 metres), reporting a maximum of 14.7% cobalt (Co), 14.9% copper (Cu) and up to 1.7 oz/ ton gold (Au). The richer mineralisation seemingly occurs in small lenses or pods within a broader zone of lower-grade mineralisation.
Modern exploration within the Mt Gilmore Project commenced in the 1980’s; PanContinental completed ground IP and magnetic geophysical surveys, gridded soil geochemistry for Cu, Au and Co, 25 trenches (1518.5 metres) and 17 RC drill holes (for 1020.82 metres).
Between 2006 and 2008, Central West Gold N.L. drilled 25 holes for 2880 metres, including 21 holes for 2604 metres at Cobalt Ridge. This work defined multiple parallel sub-vertical Co-Cu-Au sulphide lodes over a strike of 300 metres and width of between 50 metres and 120 metres. Maximum individual one (1) metre drill results include 3.38% Co, 3.18% Cu and 4.92 g/t Au.

Company Overview – Corazon Mining Limited
Corazon Mining Limited (ASX:CZN) (“Corazon” or “the Company”) is a Perth-based Australian mineral exploration company with projects in Canada and Australia.
The Company’s flagship project is the Lynn Lake Nickel-Copper-Cobalt Project in the Canadian province of Manitoba. The recent acquisition of the Mt Gilmore Cobalt-Copper-Gold Project (ASX announcement, 16 June 2016) in New South Wales (Australia) has provided Corazon with an exciting duel focus and opportunity.
Lynn Lake is a significant historic nickel-copper-cobalt mining area that ceased operation in 1976, after 24 years of continuous production. Corazon has been active in the Lynn Lake area since 2010 and has, for the first time since mine closure in 1976, consolidated the Lynn Lake Mining Centre under the ownership of one company.
The Lynn Lake Project is a development opportunity and boasts large remnant nickel-copper-cobalt resources within the historical mining centre, as well as significant drill defined resource potential from historical drilling and modern discoveries proximal to the mines. In addition to the near-mine opportunities, the exploration upside of this project is potentially enormous.
Recent work by Corazon has highlighted a very large and compelling exploration target at the nearby Fraser Lake Complex (refer to Corazon’s previous ASX announcements). The Fraser Lake Complex is predominantly under cover, twice as large as Lynn Lake, and has all the geophysical and geochemical characteristics of the Lynn Lake mineralisation.
The Australian Mt Gilmore Project provides the Company with an early-stage exploration play with indicators of large scale copper-gold systems such as porphyry and skarn intrusive related deposits. The most advanced exploration project within Mt Gilmore is the Cobalt Ridge prospect, a high-grade cobalt deposit with accompanying copper and gold mineralisation. The cobalt mineralisation within the Mt Gilmore Project provides an early focus for exploration activities for the Company.

| Modern exploration within the Project commenced in the 1980’s when PanContinental completed ground IP and magnetic geophysical surveys, gridded soil geochemistry for Cu, As, Au and Co, 25 trenches (1518.5m) and 17 RC drill holes (for 1,020.82m). Between 2006 and 2008 Central West Gold NL completed 25 RC holes and 2 core tails for 2,880m of RC and 163m of core. 21 of these holes were targeting Cobalt Ridge and 4 were completed at Gold Hill. The current Project holders have been focussed on developing data that supports a regional scale Cu-Au system along the Mt Gilmore trend. |
|
| Geology Deposit type, geological setting and style of mineralisation. |
The Project is located on the western edge of the Mesozoic Clarence- Morton Basin, where it abuts the Siluro-Devonian Silverwood Group. The Silverwood group is intruded by the Later Permian Towgon Grange Granodiorite and, at the contact, tourmaline rich bodies occur that range from veinlets to breccia-fill to dyke-like bodies up to 10m wide. The tourmaline enrichment appears to correlate with copper, cobalt and gold soil anomalies. Zoning of mineralisation has been identified, with cinnabar concentrated within the granodiorite and copper and gold concentrated within the hornfels. The Project is considered prospective for tourmaline breccia hosted Co- Cu-Au deposits, Cu-Au-Fe skarns and Quartz-sulphide vein systems, including porphyry Cu-Au deposits. |
