September 2025 Quarterly Activities Report

Coppermoly Limited (ASX: COY) (“COY” or the “Company”) is pleased to provide a summary of activities undertaken during the September 2025 quarter at their Mt Isa prospects in Cloncurry, Northwest Queensland.

QLD Tenements

No exploration activities are being carried out for EPMs 28981, 28751, EPM and 28853. However, only geological review and exploration target generation from historical data was undertaken by in-house geologists and conceptual targets being generated for the first quarter

In EPM 27835, and in EPM 27836, I.P survey and soil geochemical sampling were carried out during the quarter.

EPM 27835 and EPM27836 – Copper Valley

Exploration activities during the reporting period comprised geological evaluation, ground magnetics, I.P Survey and RC drilling were implemented during the quarter.

Drilling of 3 RC holes of 8 planned holes for 843m at Fox Tail EPM 27835 from 18 July to 31[st] July 2025. The purpose of the drilling was to text the IP resistivity and chargeability anomalies identified from the geophysical survey (asx report 21[st] July 2025)

5 holes were not drilled because no significant results were returned and only minor presence of Copper Sulphides were observed from geological logging in the 3 holes drilled although all targeted structures as revealed by geophysical survey were intersected.

859 samples including duplicates were collected and stored except for 119 samples that were sent to Townsville Australian Laboratory Services to analyse for, Au, Cu, Pb, Zn, Pb and pathfinder elements. The samples were selectively collected that represented main structures intersected during drilling.

I.P sounding and ground magnetics in EPM 27835, and I.P sounding and soil geochemical sampling in EPM 27836 has being completed and currently processing data.

Proposed Exploration Program

Since the detailed historical exploration data has been collected, it allows us to select a few well defined targets for detailed geophysical investigation, which will provide us with the drilling targets immediately. Based on the previous exploration results, six targets can be generated for conducting the further I.P. sounding surveys.

Figure 3: Targets for EPM 27835 and EPM 27836

Target One

As shown in Figure 3, an elongate EM anomaly was identified by previous exploration company. It overlaps with the stream sediment Cu geochemical anomalies and surrounded by aeromagnetic anomalies which are interoperated to be the felsic granitic intrusives. Medium level soil Cu geochemical anomalies are associated with the EM anomaly. Based on the available geological, geophysical and geochemical information, this target can be interpreted to be the intrusive-related Cu basement sulphide mineralisation at the depth, located mainly below the 200m depth.

About 0.5km[2] ground magnetic survey and six I.P. sounding lines are applied to cover the total EM anomaly area. The ground magnetic survey lines will be 100m apart with 20m a station and the I.P. sounding lines will be 100m apart with 40m a station. The I.P. sounding lines are 1200m long with 31 stations on each line. It is recommended that the measuring depth of the each I.P. sounding profile is 800m. There are total 186 I.P. sounding station within the Target One area. However, the measuring depth can be modified anytime to meet the requirement after the first set of field data has been reviewed.

It is estimated that the total field work on the Target One will be completed within three weeks. Hopefully, first drilling target can be generated out immediately after that time.

Figure 4 : Details of planned geophysical survey in Target one area

Target Two

The Target Two is also associated with Cu stream sediment regional geochemical anomalies as well as the aeromagnetic anomalies. As shown in Figure 5 the EM anomies occur on the both sides of the tongue-shaped Soxby Granite. These two EM anomalies were named as William West and William East anomalies respectively. It is interpreted that these anomalies are likely related to the Ernest Henry type of Cu-Au mineralisation. Since these two EM anomalies are highly prospective, three I.P. sounding lines are reconmended to test both EM anomalies. Each line is 1000m long with 40m per station. Totalling 156 stations are planned within the Target Two area. However, if the indentified I.P. anomalies are very promising, more I.P. sounding lines shall be applied to close the I.P. anomalies.

As the ground mag. information is very important to the discovery of this type deposit, the ground mag. survey has also applied to over the EM anomalies. The coordinates of the ground mag. survey areas area as below:

It is also hoped that the direct drilling targets shall be generated immedietly after the field work has been completed at Target Two area.

Target Six

Target Six, being the historical mining sites, is also associated with Cu stream sediment regional geochemical anomalies as well as the aeromagnetic anomalies. There is no EM data available within this area.

Three line of I.P. sounding will be applied to test the historical mining district at depth. The I.P. sounding lines are 1200m long with 31 stations on each line. With 40 metres per station there are 31 stations for each line, giving a total of 93 stations.

Ground magnetic survey will also be applied when required

EPM 28981 – Dynamite

All reported base metals is associated with fault zones. Faulted Withworth quartzite hosts the historic Fearnot mine and related Cu occurrences

Several documented copper occurrences are reported in Fearnot prospect and one unnamed occurrence, on the Eastern, faulted out limb of the Bull Creek Syncline which are associated with fault splays.

A small shaft and numerous artisanal workings are reported on surficial oxide copper occurrences over several kilometers within Fearnot.

The Bull Creek Syncline is cored with Surprise Creek “d” unit with a small window of overlying Mount Isa Group sediments in the South. The Southern end of the syncline is truncated by the Eastern extension of the Investigator Fault, a large D1 fault that is regionally copper anomalous and a structural analogue to the Mammoth Fault that hosts the Capricorn Mine deposits.

EPM 28853 – Malakoff

The magnetic anomaly targets generated by Coppermoly exploration team has been tested and the results failed to keep interest in the project. From drilling in April 2025, it revealed only rootless magnetite, pyrrhotite and pyrite with trace chalcopyrite. It is believed the anomalies are sourced from cohesive unaltered volcanics. The tenement will be surrendered.

Corporate

During the Quarter, the Company announced that it has entered into a binding sale agreement with Aldoro Resources Limited (ASX:ARN) to acquire 100% of the Wyemandoo Project in Western Australia. Under the terms of the agreement, Coppermoly will acquire Aldoro’s direct interest in the Project and 100% of the issued capital in Altilium Metals Pty Ltd—the holder of the remaining interest in Wyemandoo—for total cash consideration of $100,000. Completion of the transaction is subject to customary conditions precedent, including due diligence, regulatory approvals, and assignment documentation. The Wyemandoo Project is located in a highly prospective region of Western Australia and is considered prospective for critical minerals including rubidium, lithium, and tungsten—key elements supporting advanced electronics, clean energy technologies, and strategic industrial applications.
