DRILLING CONTINUES TO EXPAND
MINERALISED SYSTEM AT COBALT RIDGE
-
Majority of results returned from drilling at the Mt Gilmore Cobalt-Copper-Gold Sulphide Project in New South Wales
-
This phase of drilling focused on the Cobalt Ridge Main Lode – one of multiple parallel zones of mineralisation within the Project area
-
The east-west trending Main Lode is up to 35 metres in width and has been tested over an approximate 300 metre strike; drilling has focused on depths predominantly less than 170 metres below surface
-
The broad Main Lode includes multiple narrow, higher-grade sulphide rich lodes - numerous assays returned of +1% cobalt
-
Best result from this program was a high-grade intersection of 5 metres @ 2.14% cobalt

ASX ANNOUNCEMENT and new target areas at Cobalt Ridge
Corazon Mining Limited (ASX: CZN) ( Corazon or Company ) is pleased to announce assay results from its recently completed drilling program at the Mt Gilmore Cobalt-Copper-Gold Project ( Project ) in New South Wales, which was focused on the Main Lode at the Cobalt Ridge Deposit ( Cobalt Ridge ), a cobalt dominant sulphide deposit.
The majority of assay results have been returned from the drilling program that included 21 holes, with 2,233 metres of reverse circulation (RC) and 734.65 metres of core drilling, for a total of 2,967.65 metres.
Commenting on the results, Corazon’s Managing Director Brett Smith said; “this drilling has returned exceptional results and has enabled us to gain a much higher-level geological understanding of the deposit. Our ongoing work should enable us to more accurately express the potential of the Cobalt Ridge Deposit, which is our core aim, and we expect to be able to announce more about this in the coming weeks.”
Cobalt Ridge remains substantially under-drilled and there is demonstrated potential to define additional areas of mineralisation. The Cobalt Ridge Main Lode remains open in all directions and is only one of numerous parallel mineralised trends, defined by historical workings and broadspaced drilling, that have yet to be targeted with resource definition drilling.
The results from this current drilling program have provided Corazon with a very good understanding of the controls on the mineralisation - knowledge that is being used to identify additional drilling targets within Cobalt Ridge, as well as regionally with the greater Mt Gilmore Project.

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 are recoverable. Metallurgical test work completed by the Company support these assumptions. CuEq% = Cu% + (Co% * 8.35) + (ppm Au * 0.63). Metal prices used are Cu US$6,319/t, Co US$52,750/t and Au US$1,233/oz.

Cobalt Ridge Main Lode Drilling Program Overview
The recent drilling program focused on priority targets within and around the Cobalt Ridge Main Lode, one of numerous sulphide lodes defined within Cobalt Ridge. Drilling also tested some of the shallower features generated by the Company’s recently completed 3D Induced Polarisation (“IP ” ) geophysical survey, proximal to the Main Lode.
In total, 21 holes were drilled, including 2,233 metres of RC and 734.65 metres of core drilling, for a total of 2,967.65 metres. The majority of the assay results have been returned, with significant intercepts presented in Table 1 (within) and additional information regarding the drilling provided in Table 2 (attached). Results from holes MGRC057, 058, 059 and 060 are pending.
The east-west trending Cobalt Ridge Main Lode (Figure 1) has been tested over approximately 300 metres along strike, with drilling focusing on depths predominantly less than 170 metres below surface. The core of the mineralisation is approximately 150 metres in length, 15 to 35 metres in true width, with extensions continuing to the west and east. The broader zone includes multiple narrow higher-grade sulphide rich lodes. Numerous +1% cobalt assays have been returned from drilling, with the best result from this recent program of 5 metres @ 2.14% cobalt (Table 1 and Figure 2).

The recent drilling program has identified dominant trends for the cobalt-coppergold sulphides, as well as structures (faults and shears) that may control the location of the mineralisation. This data is being worked back into geological models for the Cobalt Ridge Main Lode and are also being used to identify priority target areas within parallel zones of mineralisation (Cobalt Ridge lookalike trends) to the north and south of Cobalt Ridge. As can be seen in Figure 2, the geochemical anomaly within the Cobalt Ridge area is much more substantial than just the Cobalt Ridge Main Lode.
On-going Work at Mt Gilmore
The modelling of the drilling results is underway. While the drilling to date has not exhaustively tested the Cobalt Ridge Main Lode, it is expected that the Company will still now be able to more accurately express the tonnage potential of the Cobalt Ridge area.
The regional geochemical soil sampling of the Mt Gilmore Trend remains in progress ( refer to Corazon’s September 2018 Quarterly Activities Report, ASX Announcement 31 October 2018 ). This work continues to define a substantial hydrothermal alteration footprint over several kilometers, with extensive basement anomalism in cobalt, copper and other metals. An update on this work is expected in the coming weeks.

| Location of data points Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. Drill hole locations were initially surveyed using a Garmin handheld GPSmap 64s (approximately ± 3m accuracy). Drill hole collar locations were surveyed at the end of the drilling program using a Trimble R2 Sub- Foot Rover DGPS (signal receiver) with a Trimble Juno 5D Handheld (data collector) utilising the GDA94 (Zone 56) datum. Horizontal precision is approximately 10 – 46 cm and vertical precision is about 10 – 66 cm. Down hole surveying of holes was undertaken nominally every 25-30 metres per single-shot to monitor the in-time deviation and 10 meters interval multi-shot of the whole hole as the end of hole survey using a Axis True-North Seeking Solid State Champ GYRO (accuracy: azimuth ± 0.75º,inclination ± 0.15º). |

| Data spacing and distribution Data spacing for reporting of Exploration Results. Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. Whether sample compositing has been applied. Data spacing is variable. No determination has yet been made regarding data spacing and whether sample distribution is sufficient for resource estimation. |
