Historical

The majority of COY tenements fall within a 50km radius of the world class Ernest Henry mine discovery zone.

Situated in north-west Queensland, 36km north-east of Cloncurry, The Ernest Henry discovery is a testament to the region's rich mineral wealth. Since its inception, Ernest Henry has emerged as one of the largest copper reserves in Australia and globally, boasting an estimated 167 million tonnes of ore grading 1.1% copper and 2.67 million oz of gold, with silver also being produced.

(ref: https://evolutionmining.com.au/storage/2024/10/Fact-sheet-Ernest-Henry.pdf )

This mine not only highlights the extensive copper and gold resources found in the area but also underscores the immense potential for future exploration and discoveries. The continued success of the Ernest Henry mine serves as an inspiration for miners and investors, demonstrating the region's capacity to yield significant mineral discoveries.

Projects Overview

Shuffleton Prospect – EPM 27835, 27836, 29102

Following the test drilling program in Q1 2024 at the Shuffleton Prospect, there has now been remodeling of the IP Sounding profiles and reassessment of drilling data. COY is planning to complete additional drilling previously proposed and budgeted for, as soon as the soil and Geochem analysis from Q1 2025 has been analysed and a drill rig can be mobilized to the site (Fig 6). Results from Q4 2024 Mag Surveys are due to be announce in march 2025.

Malakoff Prospect – EPM 28853

The Mt Malakoff Prospect is approx 23 km WWN of the Ernest Henry Mine. Both magnetic IOCG (iron- oxide copper gold) models and ISCG (iron-sulphide copper-gold) models will be utilised over the project area.

Drill hole geological and downhole geophysical logs provide some basement information for geophysical typing, geological interpretation. Recent high resolution aeromagnetic data can be used to scan large scale IOCG targets similar to Ernest Henry Cu-Au system (Fig. 6).

Mt Malakoff Prospect covers several magnetic anomalies under a very thin 10-50m Tertiary sediments. One of those anomalies is particularly interesting, which is a roughly 5 km x 3 km Southeast-Northwest cluster of several irregularly shaped, very high amplitude (> top 1% of data range) magnetic anomalies located northeast of the Naraku Granite. The style of possible alteration and precursor rock types evident in the basement drill hole data at the magnetic complex is very similar to that which occurs at Ernest Henry located roughly 30 km to the ESE (Fig 9).

Windy Hill Prospect – EPM 27851

Significant results from the costean are shown below * . Tl 75m at 316 ppm Cu

Windy Hill Prospect is located approximately 80 kilometres southwest of Cloncurry.

T2 160m at 0.15% Cu (including 48m at 0.3% Cu and 24m at 0.33 g/t Au)

The Windy Hill prospect, initially located by CRAE, is a mineralized breccia within Argylla Formation rhyodacite volcanics. Gossanous zones associated with quartz veining occur in the immediate vicinity of the Windy Hill breccia.

T3 184m at 0.35% Cu (including 40m at 1.2% Cu and 36m at 0.62 g/t Au)

T4 154m at 0.3% Cu (including 30m at 0.9% Cu and 40m at 0.28 g/t Au)

The area selected was thought to have good potential for copper-gold and gold mineralisations associated and magnetite concentrations, as observed at the Ernest Henry and Osborne deposits. Contacts with the 1500 Ma Wimberu Granite are thought to be prospective for this type of mineralisations system.

T5 176m at 0.17% Cu (including 18m at 0.29% Cu)

T6 150m at 0.13% Cu (including 38m at 0.28% Cu)

Late airborne magnetic survey, covering part of the tenement, reveals that the Windy Hill magnetic high complex extends over 2 km to the NNE, and CRAE and MIME ‘s works covered a small section of the Windy Hill magnetic complex (Fig. 3). The company will reprocess geophysical data and propose new survey covering the whole breccia zone as soon as practical.

T7 122m at 0.12% Cu (including 8m at 0.28% Cu)

Projects Overview

Max Hit Prospect – EPM 29102

This new application is adjacent to existing tenements along the Cloncurry Fault Zone (Figure 4 – shown in red) .

The tenement covers about 63 sqkm of Staveley/Doherty/Corella formation with greatly brecceias and alterations reported.

Some small historical copper works are recorded, iron/quartz breccias zones extend over several kilometers. This tenement is considered to be a natural extension of the south Cloncurry tenements group.

Projects Overview

Dynamite Prospect – EPM 28981

The Dynamite Project sits about 130 km north of Mount Isa and 25 km east of the Mount Oxide Copper Deposit. There are two historical copperworks in Fearnot and Dynamite. Previous reports describe that copper mineralisation can be traced discontinuously for several kilometres north and south of Dynamite Creek along the major Quilalar Fault corridor. The Quilalar Fault strikes northsouth, forming the east boundary of the Bull Creek Syncline which extends for over 90km from the Crystal Creek Block in the far south to the far north where sediments of the Mesozoic Carpentaria Basin cover the Proterozoic geology. Several significant northeast faults including the Investigator and Mammoth extended faults continue into the Bull Creek Syncline area.
