ASX Announcement

Drilling commences at Copper Blow Project, Broken Hill NSW

Kingfisher Mining (ASX: KFM) is pleased to announce the commencement of drilling at its Copper Blow Project in the highly prospective Broken Hill region of New South Wales. This marks a significant milestone in the company's exploration strategy for the area.

Copper Blow Drilling Program

The initial drilling program at Copper Blow is designed to provide infill drilling to the main mineralised lodes and improve the geological understanding of the deposit. This is a crucial first step towards establishing geological confidence, with the ultimate objective to generate a maiden Mineral Resource Estimate for the Copper Blow Project. The first round of drilling is expected to be completed during the month of December.

Copper Blow IOCG prospect (KFM 75%) hosts high grade copper gold mineralisation which has been defined by historical drilling over 600 metres of strike, historical drill results previously announced (KFM:ASX Announcement dated 25 July 2025), include:

• 16m @ 2.67% Cu, 0.62 g/t Au and 4.04 g/t Ag from 133m in 84DDHCB06

• 4m @ 6.13% Cu, 4.23 g/t Au and 12.93 g/t Ag from 188m in 17CB041

• 7m @ 3.7% Cu, 1.07 g/t Au and 5.5 g/t Ag from 126m in 17CB045

• 4m @ 3.48% Cu, 2.39 g/t Au and 5.9 g/t Ag from 177m in 84DDHCB06

• 8.22m @ 1.87% Cu, 0.53 g/t Au and 3.09 g/t Ag from 131.78m in 17CB043

• 41.2m @ 1.27% Cu, 0.4 g/t Au and 1.53 g/t Ag from 183.8m inc. 7m@ 2.23% Cu and 0.99 g/t Au from 189m in 18CB054

• 22m @ 1.08% Cu, 0.31 g/t Au and 1.63 g/t Ag from 278m inc. 15m @ 1.31 %Cu and 0.32 g/t Au from 285m in 18CB057

Kingfisher’s Managing Director Chris Bittar commented:

"We are very excited to get the first rig on the ground in more than 7 years at Copper Blow. This is the first of many prospects we plan to drill at our Broken Hill project. A successful program here will provide the foundation for an accelerated exploration strategy across the region, which is underpinned by the extremely positive long-term outlook for copper and highlights the importance of Kingfishers high-grade copper prospects.

Expanding the Broken Hill Exploration Pipeline: Allendale

Following the Copper Blow drill program, Kingfisher Mining is already focused on delivering a further phase of exploration scheduled for 2026, targeting the significant potential identified across all acquired Broken Hill tenure.

This forward planning is underpinned by historic drilling results from numerous high-priority targets. High-grade drill results from the Allendale project, including the most recent drilling in 2011 (as previously announced ASX:KFM 25 July 2025), including:

• 10m@ 16.1% Pb+Zn and 29 g/t Ag from 15m in RCAN002

• 2m@ 11.6% Pb+Zn and 39.2 g/t Ag from 47m in RCAN011

• 2m@ 13.8% Pb+Zn and 51.1 g/t Ag from 117m in RCAN016

• 2m @ 6.5% Cu and 17.6 g/t Ag from 71m in RCAN019

Regional Targeting and Geophysics Review at Copper Blow and Wellington.

Kingfisher has engaged specialist geophysical consultancy Terra Resources to assist with the in-depth review of historical exploration data across the entire NSW project portfolio, with the initial focus on Broken Hill Copper Blow project and the Macquarie arc Wellington project near Dubbo.

Copper Blow copper-gold Project (EL9840) Broken Hill, NSW (75% KFM): Mineralisation at Copper Blow is associated with a prominent 4km-long magnetic anomaly that remains largely untested outside the main Copper Blow prospect. The advanced geophysical review is specifically targeting the continuity of the IOCG system along this corridor.

Figure 4 Copper Blow magnetics with historic drilling.

Copper Blow is considered to be the largest IOCG prospect in the Broken Hill Block. Past recorded production totals 726 tonnes of copper-rich ore between 1887–1937. It has been classified as a Sisters-type deposit (Barnes 1988), who defines it as epigenetic syn- to late-tectonic strata bound Fe–Cu–Au mineralisation. Barnes 1988 describes the Sisters-type quartz–magnetite horizons as stratigraphically controlled and dominantly developed within the Thackaringa Group rocks. They comprise of quartz–magnetite zones with locally abundant apatite with accessory orthoamphibole, biotite, feldspar, epidote and retrograde chlorite–muscovite. Pyrite (commonly cobaltiferous) and/or pyrrhotite are abundant in many zones whilst chalcopyrite is minor but widespread.

Macquarie Arc, NSW, Wellington Copper-Gold Project (EL 8971) 100% KFM: Located in the Macquarie Arc within favourable volcanic stratigraphy, this project is strategically located 15km away from the significant Boda/Kaiser porphyry copper-gold deposits. The geophysical review here is focused on identifying key magnetic signatures characteristic of large-scale porphyry systems, often concealed beneath shallow cover. This work is essential for defining the first drill targets on this highly prospective ground.
