Kingfisher Mining Finalizes Extensive Drilling at Broken Hill Project; Reports High-Grade Copper-Gold Assays at Copper Blow

Reverse Circulation Drilling Yields High-Grade Copper at Copper Blow

During the June 2026 quarter, Kingfisher Mining completed a second phase of reverse circulation drilling at its Copper Blow copper-gold project, comprising 10 RC holes totaling 1,576 metres. This program targeted infill and extension drilling within an approximately 600-metre mineralised system, marking a significant advance toward resource definition. The focus was on the North Zone, building on a successful maiden drilling campaign in late 2025 that identified shallow, high-grade copper-gold mineralisation.

On 14 July 2026, post-reporting period, Kingfisher announced high-grade copper assay results from this drilling. Highlights include 26 metres at 2.57% copper and 0.75 g/t gold from 73 metres depth, featuring an internal zone of 13 metres at 4.07% copper and 1.20 g/t gold from 75 metres. Additional intercepts include 43 metres at 1.32% copper and 0.32 g/t gold from surface, with 17 metres at 2.46% copper and 0.60 g/t gold from 16 metres, and 58 metres at 0.67% copper and 0.15 g/t gold from 165 metres, including an 11-metre zone at 1.01% copper and 0.27 g/t gold from 167 metres. These represent some of the highest-grade copper results recorded at Copper Blow, confirming continuity of shallow, wide mineralised zones in the North Zone.

Strategic Alliance with Broken Hill Mines Enables Accelerated Development

Kingfisher Mining’s exploration at Broken Hill is supported by a Mining and Processing Cooperation Agreement with Broken Hill Mines (ASX:BHM), announced on 4 March 2026. This partnership provides a structured approach to assess ore processing through existing Broken Hill mining and processing infrastructure, potentially reducing capital needs and expediting development timelines. Access to established regional facilities offers Kingfisher a competitive edge by minimizing or eliminating the necessity for new processing infrastructure.

This agreement underpins Kingfisher’s broader strategy across Copper Blow, Stephens Trig, and Allendale prospects, leveraging regional infrastructure to accelerate production timelines and enhance long-term development value. The partnership is central to Kingfisher’s regional presence and development strategy, strengthening its position for future commercialisation of exploration results.

Copper Blow Progresses Toward Maiden Mineral Resource Estimate

Following successful RC drilling campaigns, Kingfisher is advancing Copper Blow toward a maiden mineral resource estimate. Total drilling since acquisition includes 16 RC holes for 2,506 metres, combining the initial late 2025 campaign and the June 2026 phase. The consistent high-grade copper-gold intercepts across multiple holes provide a strong foundation for resource definition and estimation.

Located approximately 20 kilometres southeast of Broken Hill, Copper Blow is among the most advanced copper-gold exploration projects in the region. The shallow, extensive mineralised zones in the North and South Zones offer promising exploration potential. The continuity and lateral extent demonstrated by drilling position Copper Blow as a significant asset within Kingfisher’s portfolio. The upcoming maiden mineral resource estimate will mark a key milestone in project development.

Stephens Trig Silver-Lead-Zinc Prospect Completes Maiden Drilling; Assay Results Pending

Kingfisher completed its maiden RC drilling program at the Stephens Trig silver-lead-zinc prospect during the June 2026 quarter, comprising 5 RC holes totaling 584 metres. Situated about 15 kilometres north of Broken Hill beneath alluvial cover in a low-relief river valley, Stephens Trig is one of the largest poorly exposed Broken Hill-type mineralised zones outside the main Line of Lode. It is defined by a 1.5-kilometre strike lead-zinc geochemical anomaly with zinc-rich mineralised horizons identified previously.

This drilling aimed to validate historical results and enhance understanding of mineralisation. Samples have been submitted for laboratory analysis, with assay results expected in the September 2026 quarter. These results will provide critical insight into the prospect’s mineralisation potential, supporting Kingfisher’s regional exploration pipeline that leverages local processing infrastructure.

Allendale Project Targets Extensions to High-Grade Mineralisation

Following Copper Blow and Stephens Trig drilling, Kingfisher deployed an RC rig to the Allendale project, completing 9 RC holes totaling 802 metres in the June 2026 quarter. Located roughly 40 kilometres north of Broken Hill and accessible via gazetted roads and station tracks, Allendale features a prospective 2.5-kilometre strike length targeting extensions to historically defined high-grade lead-zinc-silver mineralisation.

Samples from Allendale have been submitted for assay, with results pending. While no specific timeline was provided for these results, Stephens Trig assays are expected in September 2026. Once available, Allendale data will assist Kingfisher in evaluating mineralisation extensions and guiding future exploration decisions.

Expanded Exploration Portfolio Enhances Kingfisher’s Broken Hill Presence

During the June 2026 quarter, Kingfisher expanded its regional footprint across Broken Hill with simultaneous drilling at three complementary prospects: Copper Blow (copper-gold), Stephens Trig (silver-lead-zinc), and Allendale (silver-lead-zinc). This multi-target approach reflects a strategic effort to build a diversified project pipeline and maximise value within the Broken Hill region. The combined assets and exploration activities position Kingfisher to capitalise on multiple development opportunities and leverage shared processing infrastructure through its partnership with Broken Hill Mines.

The quarter’s 24 RC holes totaling 2,962 metres demonstrate significant exploration commitment. Targeting diverse mineralisation styles—from copper-gold at Copper Blow to silver-lead-zinc at Stephens Trig and Allendale—provides varied pathways to shareholder value creation. High-grade Copper Blow results and forthcoming assays from Stephens Trig and Allendale will clarify the company’s development potential.

Wellington Airborne Geophysical Survey Delayed; Tenure Renewed for Six Years

Kingfisher reported technical difficulties with UAV survey equipment delayed the planned airborne geophysical survey at its Wellington project, intended to enhance exploration targeting. The survey will commence once equipment issues are resolved.

Positively, Kingfisher secured tenure renewal at Wellington for six years through 2032, reinforcing its commitment to the asset and providing a medium-term window for exploration. This renewal supports potential detailed programs following resolution of UAV equipment challenges and acquisition of survey data.

Investor Focus: Resource Estimates, Assay Updates, and Development Progress

Investors should watch for key upcoming milestones including the maiden mineral resource estimate at Copper Blow, a critical near-term catalyst that will formalise resource definition and support development planning. Assay results from Stephens Trig and Allendale drilling, expected in the September 2026 quarter, will offer further insight into regional mineralisation potential.

Additionally, progress on the Wellington airborne survey and updates on the Broken Hill Mines partnership and processing pathway will be important. Regular quarterly reports and exploration announcements will track advancement. The combination of a flagship copper-gold project nearing resource definition, regional silver-lead-zinc targets, and access to established processing infrastructure provides multiple potential value drivers for shareholders over the next one to two years.
