Kingfisher Mining Limited (ASX: KFM) — Wide High-Grade Copper-Gold Intersections Extend Mineralisation at Copper Blow IOCG Prospect, NSW

14 July 2026

Price Sensitive Announcement $

Highlights:

• RC drilling confirms the continuation of wide zones of shallow, high-grade copper mineralisation in the North Zone at the Copper Blow Iron Oxide Copper Gold (IOCG) prospect near Broken Hill, NSW (KFM 75%: BHM 25%)
• Standout results representing some of the highest grades returned from the project to date include:
  • 26m @ 2.57% Cu and 0.75g/t Au from 73m, including 13m @ 4.07% Cu and 1.20g/t Au from 75m and 4m @ 7.06% Cu and 2.38g/t Au from 76m (26CBRC_081)
  • 43m @ 1.32% Cu and 0.32g/t Au from 0m, including 17m @ 2.46% Cu and 0.60g/t Au from 16m (26CBRC_080)
  • 58m @ 0.67% Cu and 0.15g/t Au from 165m, including 11m @ 1.01% Cu and 0.27g/t Au from 167m (26CBRC_082A)
• Drilling has extended high-grade sulphide mineralisation a further 50m toward a major cross fault on the North Zone, with mineralisation remaining open at depth and along strike
• Results represent another significant step toward a maiden Mineral Resource Estimate at Copper Blow
• Kingfisher’s processing agreement with Broken Hill Mines, whose concentrator is located approximately 20km from Copper Blow, provides a clear, low-capital-cost pathway to any future development
• The broader Copper Blow project sits within a prominent 4km-long magnetic anomaly that remains largely untested outside the main prospect, providing significant exploration upside

Overview:

Kingfisher Mining has delivered another strong batch of RC drilling results from its Copper Blow IOCG prospect near Broken Hill, with high-grade copper-gold intersections extending the known mineralised footprint in the North Zone and confirming the system remains open at depth and along strike — bringing the Company another meaningful step closer to a maiden Mineral Resource Estimate.

The standout result of the program, hole 26CBRC_081, returned 26m @ 2.57% Cu and 0.75g/t Au from 73m — including a high-grade core of 13m @ 4.07% Cu and 1.20g/t Au and a spectacular 4m sub-interval at 7.06% Cu and 2.38g/t Au from 76m — among the strongest individual intercepts in the project’s history. Equally compelling is 26CBRC_080, which returned a broad near-surface interval of 43m @ 1.32% Cu and 0.32g/t Au from surface, including 17m @ 2.46% Cu from 16m, demonstrating the shallow, readily accessible nature of the North Zone mineralisation. Critically, several of the strongest intercepts occur in areas previously considered to have limited mineralisation potential — pointing to additional copper inventory outside currently recognised mineralised domains and materially enhancing the project’s growth potential.

Testing at depth added further confidence, with 26CBRC_082A returning 58m @ 0.67% Cu and 0.15g/t Au from 165m, confirming the mineralised Copper Blow Shear Zone maintains significant width and strength as it extends deeper. This vertical continuity is essential for supporting the case for a large-scale resource across the 600m strike length defined in December 2025.

In the South Zone, drilling continues to confirm robust grades including 3m @ 1.99% Cu and 0.45g/t Au from 146m, adding to a growing suite of high-grade historical South Zone intercepts such as 16m @ 2.67% Cu and 0.62g/t Au and 4m @ 6.13% Cu and 4.23g/t Au. The South Zone is characterised by more discrete, higher-grade copper-gold zones compared to the broader moderate-grade envelope of the North Zone — a system geometry that broadly resembles the coat-hanger shaped geometry of the world-class Broken Hill Pb-Zn orebodies located just 20km away.

With diamond drilling now being planned to support maiden resource estimation, metallurgical assessment activities underway, and a processing agreement with Broken Hill Mines already in place, Kingfisher is rapidly building the technical and commercial foundation for a potential low-capital-cost development pathway at Copper Blow.

Company Notes:

Kingfisher Managing Director, Chris Bittar, commented: “These latest drilling results continue to demonstrate the scale and quality of the Copper Blow mineralised system. Importantly, it confirms broad zones of shallow, sulphide hosted high-grade copper mineralisation, while deeper drilling continues to show that the system remains open at depth. The results represent another significant step forward towards delivering a maiden Mineral Resource Estimate at Copper Blow. Combined with the recently executed processing agreement with BHM, the Company is rapidly progressing the project along a potential pathway towards development.”

About Kingfisher Mining Limited (ASX: KFM):

Kingfisher Mining is an ASX-listed copper-gold explorer advancing its Copper Blow IOCG prospect located approximately 20km southeast of Broken Hill in New South Wales, held 75% by Kingfisher and 25% by Broken Hill Mines. Mineralisation at Copper Blow is interpreted as an Iron Oxide Copper Gold system hosted within the Copper Blow Shear Zone across two main mineralised zones — North and South — defined over approximately 600m of strike, both remaining open along strike and at depth. The project benefits from an existing processing agreement with Broken Hill Mines, whose concentrator operates approximately 20km from site, providing a clear low-capital-cost development pathway as Kingfisher advances toward a maiden Mineral Resource Estimate.
