OUTSTANDING COBALT METALLURGICAL RESULTS Mt Gilmore Project
-
First pass flotation testwork recovers 92.2% of the cobalt, 89.0% of the copper and 75.5% of the gold in 11.1% of mass
-
Concentrate graded at 7.38% cobalt, 1.29% copper and 4.1 g/t gold
-
Testwork completed on reverse circulation drill chips – improvements expected
-
Cobalt and copper present as sulphide minerals, gold associated with sulphide
-
Viable production of a bulk concentrate for processing and separation
Corazon Mining Limited (ASX: CZN) (“Corazon” or “the Company”) is pleased to announce that preliminary metallurgical testwork completed on samples from the Mount Gilmore Project (“Project”) in New South Wales has delivered excellent results.
Simple flotation testing has yielded a recovery of 92.2% for cobalt, 89% for copper and 75.5% for gold, in a total concentrate with 11.1% mass recovery.
Testwork was conducted on a representative sample composited from reverse circulation (RC) chips from the Company’s Q4 2016 drilling program, which intersected mineralisation from near surface to depths of up to 151 metres. The composite sample contained 0.84% cobalt, 0.21% copper and 0.47 g/t gold.
These are first pass results and the Company expects that even better results will be achieved with optimisation. Due to the fine nature of the material, samples from RC chips are typically difficult to control during flotation and it can be expected that the results would improve for testwork carried out on core or rock samples.
Initial sighter-gravity concentration testwork indicated that a high-grade cobalt concentrate can be obtained from a small fraction of the feed mass. The results suggest that a 12.2% cobalt grade concentrate can be produced from only 1.31% of the initial mass. This has the potential to significantly reduce downstream equipment size and reagent consumption, improving both the Project’s CAPEX and OPEX.
Mineralogy has confirmed the Company’s expectations - cobalt is present as cobaltite, copper is present as chalcopyrite and the gold is predominantly associated with the sulphide minerals. The similar nature of the sulphide minerals, together with the gold association, has the potential to simplify the beneficiation process by the production of a bulk concentrate.
The testwork was managed by internationally recognised metallurgical consultants, METS Engineering (see competent person statement below) and independently carried out at ALS laboratories in Perth, Western Australia.

A micrograph of the initial flotation concentrate is shown in Figure 1, below. Cobaltite is abundant, exhibiting a highly reflective, violet-steely grey colour, and other sulphides including chalcopyrite and pyrite are also abundant, exhibiting their yellow/dark gold colour.

These results suggest excellent potential for the production of a concentrate for hydrometallurgical processing. The metallurgical testwork was conducted on RC chip samples obtained during Corazon’s Q4 2016 Drilling Program, and was carried out by ALS metallurgy in Perth, under the supervision of METS Engineering (METS).

| Criteria JORC Code explanation |
Commentary |
|---|---|
| Sampling techniques Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |
Pulverised rock chip samples from drilling were collected in large PVC bag on a one metre basis. Reverse Circulation drilling utilizing a face sampling hammer provided a clean, predominantly dry sample, from which subsamples were taken for laboratory analysis and geological logging. Sub-sampling provided a nominal 2kg to 3kg sample for lab analysis. Sub-sampling was completed on a 1 metre basis, or composited on a 2 metre or 4 metre basis according to geology. Core drilling included both HQ and NQ core sizes. Sampling was completed on half-core, for intervals of a minimum of 300mm and maximum of 1 metre, determined based on geological boundaries. Industry standard sample Blanks and Standards were submitted for analysis with drill samples on a 1 in 50 basis. Field duplicate samples for analysis were taken every 50 samples. All samples were submitted to an independent certified Australian laboratory for analysis. Metallurgical testworkwas completed on composited fresh (sulphide) RC drill chips. Samples provided were the complete bulk RC reject site samples. These were then composited by METS Engineering in Perth for analysis and testwork. |

| Whether sample sizes are appropriate to the grain size of the material being sampled. |
For some of the drilling, the bulk RC reject sample has been used for metallurgical testwork. Core drilling included both HQ and NQ core sizes. Sampling was completed on half-core, for intervals of a minimum of 300mm and maximum of 1 metre, determined based on geological boundaries. Drill core was halved by using an industry standard core saw. These sub-sampling techniques are industry standard and if correctly applied provide quality, representative samples for laboratory analysis.

| 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. |

| Drill hole Information A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drill hole collar o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o hole length. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
