Resource Minerals International Ltd (ASX:RMI) strengthened its exploration pipeline during the June 2026 quarter, defining large-scale copper-molybdenum and gold targets in Saudi Arabia while advancing drilling at its Mpanda Copper-Gold Project in Tanzania.
The company completed interpretation of a high-resolution ground magnetic survey at the Wadi Salamah Project, where two deep-seated magnetic anomalies covering around 16 square kilometres were identified in the northern part of the licence.
RMI believes the anomalies may represent large intrusive bodies prospective for porphyry-style copper-molybdenum mineralisation.
Six major fault structures associated with the regionally significant Najd Fault System corridor were also identified, leading to the definition of three priority zones for follow-up exploration and drilling.
The company is now undertaking geological mapping and rock-chip sampling at Wadi Salamah and the nearby Shaib Marqan Project ahead of separate planned 5,000-metre drilling programs during the September quarter of 2026.
Wadi Salamah survey identifies large intrusive targets
The 98.7-square-kilometre Wadi Salamah licence is within Saudi Arabia’s Arabian Shield, a mineral-rich geological region that remains relatively underexplored using modern techniques.
RMI’s survey comprised 1,010 line kilometres of ground magnetics across 225 survey lines, designed to identify structural controls and concealed mineralised systems beneath surface cover.
Interpretation divided the project into northern and southern target areas.
In the northern sector, the H1 and H2 magnetic anomalies have been interpreted as potentially deep-seated intrusive bodies. Contact zones between the anomalies and surrounding sedimentary rocks are considered priority targets for copper and molybdenum mineralisation.
The company also identified fault structures that may have acted as conduits for mineralising fluids.
In the southern sector, exploration is focused on structurally controlled gold and silver mineralisation associated with fault intersections, linear magnetic lows and historic workings.
Three priority zones have been defined across the project, including a northern copper-molybdenum target and two southern gold-silver areas.
RMI is completing detailed geological mapping and surface sampling, supported by induced polarisation and resistivity surveys. The results will guide a combined reverse circulation and diamond drilling program expected to begin late in the September quarter.
Shaib Marqan targets supported by high-grade surface gold
At Shaib Marqan, a previous magnetic survey identified seven major fault systems and four priority exploration zones.
The targets show a strong spatial relationship with previously reported surface sampling results of up to 40.35 grams per tonne gold.
Shaib Marqan lies within the Ar Rayn Terrane near the major Al Amar fault zone, an area prospective for volcanogenic massive sulphide copper-zinc deposits, orogenic and epithermal gold, and iron oxide copper-gold systems.
Follow-up mapping, rock sampling and geophysical work are underway, with an initial drilling program of up to 5,000 metres scheduled to start during the September quarter.
Together, the Wadi Salamah and Shaib Marqan programs represent a planned 10,000 metres of drilling across RMI’s Saudi Arabian portfolio.
Replacement contractor resumes Mpanda drilling
In Tanzania, RMI continued a staged 2,500-metre reverse circulation drilling campaign at its Mpanda Copper-Gold Project.
The program is testing five priority areas — Stalike, Ibindi, Kabungu, Kabungu North and Kabatini West — selected using magnetic interpretation, historic workings, surface sampling and previous drilling.
Stalike includes an anomaly extending for about five kilometres along an east-west fault, where historical grab sampling returned copper grades of up to 13.58% and gold grades of up to 3.24 g/t.
At Kabungu North, earlier rock-chip sampling produced results including 36.7 g/t gold and 11.89% copper.
Drilling was delayed after the original contractor experienced rig performance issues. RMI demobilised that contractor and appointed a replacement, which has since commenced work.
Initial assay results are expected to be reported in the near term, with a second-phase drilling program anticipated during the September quarter.
Placement supports expanded exploration
RMI raised $3.5 million before costs through a placement of 87.5 million shares at $0.04 each.
The funds are being directed toward Mpanda drilling, follow-up work and drilling across the two Saudi Arabian projects, and general working capital.
The company spent about $665,000 on exploration during the quarter and finished June with approximately $2.12 million in cash.
RMI also reported access to a $5 million funding facility, giving it total available funding of about $7.12 million and an estimated 8.75 quarters of funding at the reported rate of expenditure.
