NEWLY DISCOVERED COBALT ANOMALIES
SIGNIFICANTLY EXTEND COBALT RIDGE FOOTPRINT
-
Surface sampling at the Cobalt Ridge prospect within the Mt Gilmore Project identifies four new cobalt-copper-gold geochemical anomalies
-
New anomalies significantly increase the cobalt target at Cobalt Ridge to ~3km x 1km – mineralisation is open in all directions
-
Results strengthen Corazon’s exploration model for the Mt Gilmore Project to host significant cobalt dominant sulphide deposits
-
Surface geochemistry, mapping and geophysics currently underway to further test anomalies and define additional drill targets at Cobalt Ridge for Resource definition and new discovery drilling
Corazon Mining Limited (ASX: CZN) ( Corazon or Company ) is pleased to announce the discovery of four new cobalt-copper-gold anomalies at the Cobalt Ridge prospect ( Cobalt Ridge ), located within the Company’s Mt Gilmore Project ( Project ) in New South Wales.
The definition of these new geochemical anomalies extends the known cobalt-mineralised system at Cobalt Ridge to an area of approximately three (3) kilometres in strike and one (1) kilometre in width, which remains open in all directions. These cobalt-copper-gold anomalies strengthen Corazon’s exploration model for the entire Project area to potentially host significant cobalt dominant sulphide deposits, in addition to the known mineralisation at the Cobalt Ridge prospect.
The Cobalt Ridge prospect is focused on a small area of outcrop where past exploration and smallscale mining identified cobalt dominant cobalt-copper-gold sulphide mineralisation. The new anomalies were identified from a recently completed geochemical soil-sampling program testing for extensions to defined mineralisation (Figure 1).
Exploration at the Project is ongoing and includes additional sampling, mapping and geophysics, which will be used to define specific targets for the next phase of drilling.
Geochemical Anomalies
To date, the results of Corazon’s exploration work at Cobalt Ridge suggests the geochemical dispersion of metals within the soil profile is restricted due to the carbonate rich nature of the host rocks. As such soil sampling has proven to be a good indicator of mineralised basement.
Four new areas of interest have been identified from this latest soil-sampling program. The generated anomalies are of lower tenor than that discovered over the Cobalt Ridge outcrop areas, where mineralisation outcrops. However, they are not closed off and may represent the margins of much larger soil anomalies. Field validation, infill and extension soil sampling is currently underway to further test these features.

In total 310 samples were submitted along with six duplicate samples, blanks and standards (refer to Table 1, attached). Peak assay results included 133ppm cobalt, 1360ppm copper and 1500 ppb gold. By comparison, past results for the outcropping Cobalt Ridge areas peaked at 271 ppm cobalt, 4320 ppm copper and 900 ppb gold.
Corazon’s plans for a larger systematic regional soil program are well advanced. This work will enable the development of a high-quality cobalt target pipeline for drill testing and discovery. Targets of priority include historic copper workings and identified areas of hydrothermal alteration.

Mt Gilmore Project Overview
The Mt Gilmore Project is located 35 kilometres from the major regional centre of Grafton in northeastern New South Wales. Corazon owns a 51% interest in the Project, and the exclusive right to earn up to an 80% interest in the Project.
Recent drilling by Corazon at Cobalt Ridge has validated historical mining and exploration results and confirmed the presence of multiple zones of cobalt-copper-gold sulphide mineralisation over a strike length of at least 300 metres. The mineralisation remains open along strike and at depth. The Main Cobalt Lode has been the primary target of the Company’s recent drilling (and much of the historical drilling). This lode is up to 25 metres in true width and contains multiple narrow zones of higher-grade mineralisation.

Corazon has defined the prospective 18 kilometre “Mt Gilmore trend”, within the Project area; it includes more than 25 historic working, 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) in addition to the cobalt mineralisation.
Although mapping indicates extensive hydrothermal alteration and copper-gold mineralisation at surface, very little modern exploration has been undertaken at the Project. Aside from small-scale historic 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).
