Highlights

New high-grade veins at Wadi Jarir return rock chip grades of up to 16.6 g/t, 15.8 g/t, and 13.9 g/t gold, extending the mineralised corridor to 9 kilometres.
Matar Prospect extended 500 metres with rock chip results of up to 19.5 g/t, 15.1 g/t, and 14.2 g/t gold.
Copper-molybdenum anomalism at Karak is suggestive of a porphyry or intrusion-related gold system beneath the mapped vein corridor.
Approximately 400 new vein targets identified from high-resolution drone photogrammetry at Wadi Jarir and Karak.
Maiden KSA drilling program expected to commence December 2026, targeting Wadi Jarir, Matar, and Karak.

Peako Limited (ASX:PKO) has reported a series of high-grade gold rock chip results from its ongoing exploration programs across its Kingdom of Saudi Arabia (KSA) project portfolio, further extending the scale and complexity of the gold systems under investigation. The results come from three separate prospect areas — Wadi Jarir, Matar, and Karak — all located within the Central Arabian Gold Region, a Jurisdiction with a well-established record of multi-million-ounce gold discoveries.

Latest Development

At Wadi Jarir, phase-two mapping and sampling has identified multiple new high-grade gold-bearing veins, with rock chip assays returning up to 16.6 g/t, 15.8 g/t, and 13.9 g/t gold. These results extend the mineralised vein corridor to approximately 9 kilometres, up from the previously reported extent, and include significant silver grades at Wadi Jarir South of up to 74.5 g/t. At Matar, 500 metres of additional vein strike was identified through follow-up sampling, with new high-grade results of up to 19.5 g/t gold. The Matar prospect sits 2.5 kilometres from an operating gold mine and is interpreted to share similar geological controls to that deposit. At Karak, multi-element geochemical results reveal a copper-molybdenum anomalism characteristic of porphyry gold-copper or reduced intrusion-related gold systems, suggesting that a larger magmatic system may underlie the high-grade veins mapped at surface.

Company Background

Peako's KSA portfolio covers approximately 862 square kilometres across six projects within the Central Arabian Gold Region, all located within 65 kilometres of operating multi-million-ounce gold mines. The Company has identified that historical wide-spaced drilling at Wadi Jarir largely targeted zones between primary veins, missing the main structures and intersecting mineralisation interpreted as wallrock alteration halos. The upcoming drilling program is specifically designed to test the high-grade vein system directly, following up on historical intercepts that the Company believes ended in mineralisation.

Sector Context

Saudi Arabia hosts one of the most underexplored Tier-1 gold endowments globally, with the Arabian-Nubian Shield sharing comparable geology with leading gold provinces in Western Australia, West Africa, and Canada. The region has historically been dominated by a single state-affiliated operator, limiting access to modern systematic exploration. The liberalisation of the Saudi Mining sector in recent years has opened the region to international companies, creating early-mover discovery opportunities. The Central Arabian Gold Region in particular hosts multiple multi-million-ounce deposits, and Peako's project areas are located in direct structural proximity to these known mineralised systems.

Market Perception

The extension of the Wadi Jarir vein corridor to 9 kilometres, combined with high-grade vein results at Matar and systemic porphyry-style anomalism at Karak, adds breadth to the Company's KSA exploration story. The identification of approximately 400 new vein targets from drone photogrammetry at Wadi Jarir and Karak provides a substantial target pipeline ahead of the maiden drilling program. The pending magnetic survey interpretation, expected in coming weeks, is likely to further refine structural understanding of the main drill targets. Historical intercepts with high-grade downhole mineralisation at the bottom of holes reinforce the Company's confidence that follow-up drilling will penetrate the primary vein systems.

Growth Drivers

Several factors support continued exploration momentum in Peako's KSA program. The Arabian-Nubian Shield's established geological productivity for large orogenic and intrusion-related gold deposits provides a favourable regional framework. The identification of porphyry-style copper-molybdenum anomalism at Karak adds a potential district-scale discovery dimension beyond the vein-hosted targets. Drone photogrammetry has efficiently generated a large target inventory, extending exploration reach without proportionate field expenditure. The staged approach — surface sampling and Geophysical surveys preceding drilling — allows scientific targeting before committing significant capital.

Risks and Challenges

Rock chip sampling of quartz veins is by nature selective and typically highlights the highest-grade portions of a system. The conversion of surface results to drill-proven mineralisation is not guaranteed, and vein systems can be discontinuous at depth. Saudi Arabia is a relatively new international exploration jurisdiction, with operating environment risks including geopolitical complexity, particularly noted by the Company in relation to the broader Middle East security situation. Logistics for rig mobilisation into the country and the approval process for drilling are operational factors that the Company has acknowledged. The timeline for the maiden drilling program remains subject to rig arrival.

Recent Announcements

In addition to the results reported in this announcement, Peako has previously reported rock chip results of up to 41.5 g/t gold at Ad Dirabi and up to 11.41 g/t gold at Ad Dirabi and 5.05 g/t gold at Bulgah East from first-phase mapping activities. Magnetic surveys commenced across key drilling targets in August 2026. The Company continues to monitor the Middle East security situation and has stated that field activities are unaffected given the remote location of its project areas.

Key Insights

Peako has extended the geographical and geological scale of its KSA gold discovery opportunity, with a 9-kilometre vein corridor at Wadi Jarir, high-grade new discoveries at Matar, and porphyry-style anomalism suggesting deep magmatic system potential at Karak. The addition of approximately 400 new vein targets identified from drone imagery adds further depth to an already well-populated drill target inventory. With the maiden KSA drilling program anticipated in December 2026, the Company is approaching a catalyst-rich period of exploration that could materially advance understanding of the size and character of these gold systems.

FAQs

Q: Where are Peako's KSA projects located?

A: Peako's six projects cover approximately 862 square kilometres in the Central Arabian Gold Region, all within 65 kilometres of operating multi-million-ounce gold mines, including nearby deposits of significant scale.

Q: What are the main prospects reported in this announcement?

A: The announcement covers Wadi Jarir, where the gold vein corridor has been extended to 9 kilometres; Matar, where high-grade veins have been extended by 500 metres; and Karak, where multi-element geochemistry suggests porphyry or intrusion-related gold system potential.

Q: What is the significance of the copper-molybdenum anomalism at Karak?

A: Elevated copper and molybdenum associated with gold veins at surface is a geological signature characteristic of porphyry copper-gold or reduced intrusion-related gold systems. This suggests the potential for a larger magmatic system underlying the veins mapped at surface, adding a district-scale discovery dimension.

Q: When is the maiden KSA drilling program expected to commence?

A: The maiden drilling program is expected to commence in December 2026, subject to the arrival of the contractor rig in Saudi Arabia.

Q: Does Peako have 100% ownership of its KSA projects?

A: Yes. Peako holds 100% interest in its KSA licences through its subsidiary, Desert Ex LLC. A 1% Net Smelter Return royalty applies to all minerals extracted.
