Haranga Extends Gold Strike to 800m in Senegal With System Open at Depth

Haranga extends gold mineralisation to over 800 metres at Ibel South

Haranga Resources has confirmed a potential >800m continuous mineralised gold trend at TMS Anomaly 3, Ibel South Gold Project, Senegal, following Phase 2 aircore drilling. The 65-hole programme, totalling 3,197 metres, tested shallow depths of 25m to 85m across only ~800m of a broader ~5km gold anomalous corridor. Mineralisation remains open at depth and along strike, with multiple holes ending in gold-bearing altered greywacke, indicating the system extends into bedrock. The programme was completed safely, on schedule and within budget.

Key intercepts confirm lateral extent of gold system

Phase 2 drilling has delivered multiple wide, continuous intercepts above the 0.3g/t Au reporting cut-off, confirming a laterally extensive gold system. Results are reported as 4m composite samples, distinct from Phase 1’s 1m sampling. Several holes ended in mineralisation, indicating the system extends into fresh bedrock beneath the supergene cover.

Wide, continuous intercepts support the thesis of a substantial gold system warranting deeper investigation. The lateral extent demonstrated across >800m of strike provides significant runway for resource growth, particularly given that only ~800m of the broader ~5km anomalous corridor has been tested, leaving large portions untested.

What is Birimian orogenic gold mineralisation?

Birimian-aged orogenic gold systems are the dominant deposit type across West Africa’s prolific gold belt, hosting world-class mines in Senegal, Mali and Burkina Faso. These deposits form within volcanic-sedimentary sequences during regional deformation, typically controlled by major shear zones and faults. Mineralisation at Ibel South is hosted in altered greywacke comparable to units of the Mako Supergroup, which hosts major deposits including Massawa and Douta.

Key geological features observed at Ibel South include albite-epidote alteration, quartz veining, silicification, and disseminated to vein-hosted pyrite. Large quartz veins up to 15-20m apparent thickness have been intersected in the supergene profile, though not yet in bedrock. Understanding the deposit type helps investors contextualise Ibel South within a proven gold-producing geological setting. Birimian gold systems have delivered multiple multi-million ounce deposits across the region.

Structural interpretation points to potential high-grade zones

Review of drill data reveals flexures in the mineralised trend, suggesting possible cross-faulting. Phase 1 high-grade zones exhibited increased fracturing and deeper oxidation compared to Phase 2 drill logs, consistent with greater structural activity. This interpretation will guide future drill targeting for potential higher-grade dilation zones.

Three structural indicators have emerged from the combined Phase 1 and Phase 2 datasets:

1. Flexures in mineralised trend indicating possible cross-faulting
2. Increased fracturing and deeper oxidation in Phase 1 high-grade zones
3. Large quartz veins (15-20m) in supergene profile, yet to be tested at depth

Structural complexity in orogenic gold systems often controls where high-grade shoots develop. Haranga’s interpretation creates a clear exploration model for targeting future drilling. The company notes that if the interpreted cross-faulting extends into untested TMS anomalies, it may represent a district-scale structural control on mineralisation.

Management’s view on the discovery potential

Managing Director Peter Batten has framed the Phase 2 results as confirmation of a laterally extensive, structurally controlled orogenic gold system. His commentary reinforces the technical significance and signals management confidence in the asset’s scale potential.

Peter Batten, Managing Director

“Phase 2 drilling has delivered an important outcome by confirming a laterally extensive, structurally controlled orogenic gold system with potential continuity of more than 800 metres of strike and which remains open at depth and along strike.”

Batten noted that Phase 2 mineralisation aligns with regional expectations for economic gold deposits in the West African Birimian Belt, and the quartz vein presence suggests structural components that could indicate dilation zones within the mineralised trend.

Next steps and Q1 CY2026 drilling plans

Haranga plans to commence further drilling in Q1 CY2026, subject to the completion of required administrative and regulatory approvals. The upcoming programme will pursue three objectives:

1. Test Priority 1 and Priority 2 TMS anomalies (currently untested)
2. Drill potential cross-fault sites within the northwest TMS anomalism
3. Additional drilling of the high-grade zone from Phase 1, targeting fresh bedrock and down-dip/along-strike extensions

Geological relogging is underway to refine the model ahead of deeper drilling. Current drilling has been limited to 25-85m depth, testing only the supergene profile and upper bedrock levels. Multiple untested targets provide optionality for further discovery across the 5km anomalous corridor.

Project context within Haranga’s portfolio

Ibel South sits in the Kéniéba Inlier, a highly prospective gold region in southeastern Senegal. The project benefits from proximity to major structures including the Mako Shear Zone and Main Transcurrent Zone, both associated with world-class gold deposits.

Haranga offers dual-jurisdiction gold exposure with an advanced permitted project in California (Lincoln Gold Project) and an early-stage discovery opportunity in West Africa. The Lincoln project benefits from significant existing infrastructure and is fully permitted for mining. The company has commenced an underground diamond drilling programme designed to support delivery of a maiden JORC Resource.
