RMI Targets 10,000m Saudi Drilling Campaign in September Quarter

Resource Minerals International (ASX: RMI) is preparing to commence a combined 10,000-metre drilling campaign across two Saudi Arabian exploration projects before the end of the September 2026 quarter. The program spans seven priority targets at the Wadi Salamah and Shaib Marqan licences, covering approximately 190.5 square kilometres of the Arabian Shield, and marks the company’s transition from surface-based geophysical work to direct drill testing. What follows is a breakdown of what RMI is drilling, the geological case behind each project, and the near-term catalyst timeline investors should monitor as results begin flowing later this quarter and beyond.

Two Saudi projects, one drilling quarter: how RMI is structuring its campaign

A 10,000-metre program split evenly across two licences is a significant commitment for any ASX-listed junior explorer. RMI has structured the campaign to deliver up to 5,000 metres at each project, with Shaib Marqan drilling set to commence during the September quarter and Wadi Salamah following late in the same period.

The timing is not coincidental. Both projects reached drill-readiness in parallel after quarters of systematic geophysical surveying, surface sampling, and target refinement. Seven priority zones, three at Wadi Salamah and four at Shaib Marqan, are now defined well enough to justify first-pass and maiden drill programs simultaneously.

Emerging jurisdiction exploration carries a distinct risk profile compared to projects in established mining districts: permitting timelines, in-country logistics, and regulatory familiarity all affect how efficiently a junior can move from geophysical anomaly to drill result and, ultimately, to resource definition.

What makes the Arabian Shield a legitimate exploration destination

The Arabian Shield is a Precambrian terrane, a large block of ancient crustal rock, whose mineral prospectivity has long been recognised but has seen limited application of the systematic modern exploration techniques routinely deployed across comparable regions in Australia, West Africa, and the Americas. That gap between known geological potential and actual exploration activity is central to RMI’s positioning.

Long-cycle mining supply dynamics are part of the structural backdrop that makes underexplored jurisdictions like the Arabian Shield attractive to capital: when major deposit discovery rates decline globally, regions with known geological prospectivity but limited modern exploration effort attract disproportionate early-mover interest.

The Shield’s geology hosts several deposit styles directly relevant to the company’s two projects:

• Porphyry copper-molybdenum systems
• Volcanogenic massive sulphide (VMS) copper-zinc deposits
• Orogenic and epithermal gold mineralisation
• Iron oxide copper-gold (IOCG) systems

Saudi Arabia’s broader push to expand its domestic mining sector as part of economic diversification has provided an additional policy tailwind, encouraging international junior explorers to advance projects from early-stage geophysics through to drilling. For an ASX-listed company committing to a 10,000-metre program, the combination of underexplored geology and a supportive regulatory environment provides the rationale for operating in a jurisdiction less familiar to Australian investors.

The Saudi Vision 2030 mining strategy has positioned mineral exploration as a cornerstone of the kingdom’s economic diversification agenda, underpinning regulatory modernisation efforts that have made foreign junior explorer entry more accessible through streamlined licensing and a competitive investment framework.

Wadi Salamah: from 1,010 line kilometres of magnetic data to three drill-ready priority targets

The geological case at Wadi Salamah was built methodically. During the June 2026 quarter, RMI completed a high-resolution ground magnetic survey comprising 1,010 line kilometres across 225 survey lines. Interpretation of that dataset revealed a project that divides into two distinct sectors, each hosting different mineralisation styles.

Northern sector: porphyry copper-molybdenum targets

Two substantial magnetic anomalies, designated H1 and H2, have been interpreted as deep-seated intrusive bodies collectively spanning approximately 16 square kilometres. Contact zones between these interpreted intrusives and surrounding sedimentary rocks are considered primary targets for copper and molybdenum mineralisation.

Six significant fault structures associated with the regionally important Najd Fault System corridor have been identified across the northern sector. These faults are interpreted as potential fluid conduits, pathways through which mineralising hydrothermal fluids may have moved along intrusive-sediment contacts.

Southern sector: structurally controlled gold-silver targets

Two gold-silver priority zones in the southern sector are defined by fault intersections, linear magnetic lows, and the presence of historic workings. Those old workings provide empirical evidence that elevated metal values were recognised in the area before modern exploration tools were applied.

Ahead of drilling, RMI is undertaking refinement work to further constrain these targets:

• Detailed geological mapping
• Surface rock chip sampling
• Induced polarisation (IP) and resistivity surveys

A combined reverse circulation (RC) and diamond drilling program of up to 5,000 metres is scheduled to commence late in the September 2026 quarter.

Shaib Marqan: how four maiden drill zones were built on high-grade surface gold results

Surface sampling at Shaib Marqan has returned gold assays of up to 40.35 g/t, with additional results of 9.62 g/t, 7.03 g/t, and 5.72 g/t gold.

Those numbers are the headline. Located within the southern section of the Ar Rayn Terrane, in proximity to the major Al Amar fault zone, Shaib Marqan’s 91.8 square kilometre licence area is being targeted for multiple deposit styles:

• Volcanogenic massive sulphide (VMS) copper-zinc
• Orogenic gold
• Epithermal gold
• Iron oxide copper-gold (IOCG)

A prior magnetic survey across the licence delineated seven major fault systems, which led to the definition of four priority exploration zones that will anchor the maiden drilling program. Follow-up geological mapping, rock chip sampling, and additional geophysical work are currently underway to refine these targets ahead of the drill bit.

The maiden program of up to 5,000 metres is scheduled to commence during the September 2026 quarter. High-grade surface gold results spatially linked to structurally defined targets provide a direct case for first-pass drilling, though outcomes remain subject to geological uncertainty and results may or may not confirm surface interpretations at depth.

Maiden drill intercepts at structurally controlled gold targets have a wide range of outcomes across the junior exploration sector, with some programs confirming surface grades at depth and others returning narrower or lower-grade intersections that require follow-up work before a resource picture emerges.

Drilling transitions from surface anomaly to newsflow catalyst

The shift from surface geophysics to drilling is one of the most significant inflection points in the junior exploration cycle. It is the stage at which geological hypotheses, however well-supported by magnetic data, surface sampling, and structural interpretation, face their first real test underground.

For Resource Minerals International (ASX: RMI), the near-term sequence is clear:

1. Shaib Marqan maiden drilling commences during the September 2026 quarter
2. Wadi Salamah drilling commences late in the September 2026 quarter
3. First drill results expected during and after the September 2026 quarter

The dual-project structure matters here. Rather than a single binary drill result at one project, RMI is positioned for a sustained period of exploration updates across seven priority zones and two distinct geological settings. That cadence of newsflow, spread across multiple targets and commodity types, gives investors several potential catalysts to monitor over the coming months.

RMI’s Saudi program marks a disciplined escalation from geophysics to drill bit

RMI’s combined 10,000-metre campaign across Wadi Salamah and Shaib Marqan represents the culmination of systematic surface-based work: magnetic surveys totalling over 1,000 line kilometres, surface sampling that returned gold assays of up to 40.35 g/t, and structural interpretation that defined seven priority zones across two licences. First-pass results at Shaib Marqan and maiden Wadi Salamah results are both expected before the end of 2026.

Drilling outcomes remain subject to geological uncertainty. Surface and geophysical anomalies do not guarantee subsurface mineralisation, and results may or may not confirm the interpretations that underpin each target.
