Contiguous Ad Duwayhi Belt Gold Project
This contiguous 236 km² licence block lies within the 165 km NNW-striking Ad Duwayhi–Wurshah–Umm Matirah Gold Belt, one of the Arabian Shield’s most well-endowed belts.
The Ad Duwayhi gold mine, ~50 km to the NNW, hosts 3.1 Moz Au at 1.3 g/t — a world-class orogenic gold deposit anchoring the prospectivity of Almasar’s structural corridor. Further north, the Mansourah-Massarah deposit — Saudi Arabia’s largest gold resource — hosts 10.4 Moz Au at 2.8 g/t Au, demonstrating the scale of orogenic gold systems within the Afif Terrane.
ND28–ND31–ND36 is prospective for structurally controlled orogenic gold and intrusion-related magmatic–hydrothermal systems, including porphyry-style and affiliated epithermal, skarn, IOCG and intrusion-related gold systems. The licences lie on the boundary with the older 1.7–1.8 Ga Khida Terrane, a lithological contrast replicated at licence scale, with volcanic and volcaniclastic sequences juxtaposed against carbonate-clastic horizons and cut by intrusive bodies. NW-trending structures, including the Ruwah Fault Zone to the south and Ar Rika Fault Zone to the north, bound the belt; gold mineralisation structurally controlled and spatially associated with intrusive activity in volcano-sedimentary successions. Reconnaissance observations confirm silicification, quartz-carbonate veining and chlorite-epidote alteration — tangible indicators of past hydrothermal fluid movement.
No systematic drilling has been completed on any of the three licences, leaving a substantially untested footprint within a belt proven to host world-class gold endowment at Ad Duwayhi. Readily accessed by maintained roads and supported by Almasar’s local village field office, the project is well placed for rapid geological mapping, ground geophysics, targeted geochemistry and drilling — providing a clear route to refining and testing targets across one of the Company’s most compelling project areas.

ND41
Porphyry-Style Potential on the Ad Duwayhi Belt Margin
ND41 is Almasar’s most texturally distinctive project — a 94 km² licence immediately south of the ND28/31/36 block, defined by pervasive, intense epidote-rich alteration in porphyritic mafic-intermediate volcanics.
This propylitic-style overprint — developed across feldspar phenocrysts, groundmass and fracture networks — is a typical distal expression of a magmatic-hydrothermal system, the kind of alteration halo that, when followed inward, can lead to potassic cores hosting porphyry Cu-Au or intrusion-related gold mineralisation, with scale and intensity pointing to a hydrothermal system of meaningful dimensions.
In the broader Arabian-Nubian Shield context, Jebel Ohier in Sudan demonstrates that porphyry-style mineralisation can reach 2.3 Mt CuEq contained metal within the ANS, while the shield also hosts porphyry and intrusion-related gold systems, including the Mibari prospect in Saudi Arabia. ND41’s structural setting provides the fluid pathway architecture these systems require. Reconnaissance work identified possible historic trenching targeting epidote-quartz veining in porphyritic rhyolite, suggesting earlier explorers recognised the same hydrothermal signals Almasar’s geologists documented in 2025.
ND41 represents a compelling porphyry-style target defined by the scale and intensity of its alteration system. With field mapping complete and geochemical sampling underway, Almasar is advancing toward drill-target definition on a licence with district-scale hydrothermal architecture already confirmed at surface.

NS142
As Safra Belt Gold & Base-Metal Opportunity
NS142 sits within the Sukhaybarat–As Safra Gold Region of the Afif Terrane, a large, well-endowed metallogenic corridor extending ~275 km through the Al Habla and Humaymah areas.
The belt hosts multiple recognised gold mines and prospects, including the operating 1 Moz Sukhaybarat and 2.6 Moz Bulgah gold mines, ~40 km NE and ~30 km south, respectively. The 90 km² licence is underlain by arc-related volcanic and volcaniclastic rocks of the Nuqrah Formation and lies within the western Nuqrah–As Safra VMS and Orogenic Gold Belt, where VMS mineralisation and later structurally controlled orogenic gold systems are recognised within volcano-sedimentary sequences associated with the Nabitah Suture Zone.
Within the licence, two gossanous metallic occurrences are recorded in the Saudi Geological Survey’s mineral occurrence database, hosted in andesite and tuff with silicification and structural controls common to both deposits, alongside preserved historic drill collars. Almasar’s initial soil survey has defined coherent multi-element anomalies, notably As–Sb with local Au, open to the east, and interpreted as potential vectors toward structurally focused hydrothermal systems.
NS142 combines genuine belt-scale pedigree, favourable host geology and tangible first-pass geochemical encouragement. With systematic mapping underway, to be followed by ground magnetics, extended soil sampling and success-based drilling, NS142 is well positioned to advance from regional anomaly to defined drill target within a corridor already proven to host significant gold endowment.
