Sankamap Metals Inc. (CSE: SCU) (‘Sankamap’ or the ‘Company’) is pleased to announce the completion of data processing and reports from Expert Geophysics for the 374 line-kilometer Airborne Magnetotelluric EM Survey (‘Mobile MT’) completed in July 2025. The survey covered 3,500 hectares of Sankamap’s 4,500-hectare (‘Ha’) Kuma property (‘Kuma’) (populated areas excluded) located 37 kilometers (‘km’) southeast of Honiara in south-central Guadalcanal, Solomon Islands.

CEO John Florek commented:

‘We are very encouraged by the results of the airborne geophysical survey, which reveal clear signatures consistent with porphyry-style mineralization. The strong alignment between these geophysical features, surface geochemistry, and alteration mapping gives us greater confidence in the continuity of mineralization at depth and helps refine our upcoming drill targets.’

Highlights

• The results of the Mobile MT survey at Kuma reveals a broad 5 x 2 km ring-shaped zone of high conductivity that flanks a central 2 x 3 km highly resistive feature (see Figure 2), with the conductive feature spatially correlating to the mapped lithocap.
• Geophysical data indicate potential for multiple intrusive centers and porphyry systems, while the alignment of magnetic and conductive trends suggests structural controls or fluid pathways associated with mineralization.
• The resistive and conductive trends display typical porphyry signatures, similar to other economic porphyry systems currently being mined.

The results from the 2025 Mobile MT survey delineate resistive and conductive features consistent with porphyry, epithermal, and skarn-style mineral systems. The geophysical data further corroborate earlier surface exploration findings at the Kuma property, which delineated a well-developed lithocap exceeding two kilometers in extent. Hyperspectral analysis has outlined extensive phyllic, argillic, and advanced argillic alteration zones, while grab sampling has returned impressive assay results of up to 11.7% copper (‘Cu’) and 13.5 g/t gold (‘Au’), underscoring the strength and continuity of mineralization within the system.

The Kuma Project is strategically located along a highly prospective trend that hosts several major deposits; Lihir containing 71 Moz Au¹ (310 Mt containing 23 Moz Au at 2.3 g/t Proven+Probable (‘P&P’), 520 Mt containing 39 Moz Au at 2.3 g/t indicated, 81 Mt containing 5 Moz Au at 1.9 g/t measured, 61 Mt containing 4.9 Moz Au at 2.3 g/t Inferred) and Panguna containing 19.3 Moz Au + 5.3 Mt Cu² (1.5 Mt containing 16.1 Moz Au at 0.33 g/t and 4.6 Mt Cu at 0.3 % Indicated, 300 Mt containing 3.2 Moz Au 0.4 g/t and 0.7 Mt Cu Inferred), both share geological similarities to the Kuma project.

Technical Discussion

Porphyry Cu-Au systems can exhibit a broad spectrum of electromagnetic (EM) responses, reflecting different host rocks, alteration styles, erosional levels and geological conditions unique to each system. For example, systems with intact lithocaps, which is potentially the case at Kuma, often differ from those with eroded or exposed mineralized cores, producing either predominantly conductive or resistive EM signatures.

As at Kuma, most calc-alkaline porphyry systems exhibit elevated electrical conductivity, largely attributable to extensive pyritic halos and mica-rich alteration zones that envelop a potassic core (as displayed in Figure 2 and 3). This core typically appears as a distinctly resistive feature, reflecting zones of magnetite or K-feldspar alteration characterized by relatively low sulfide concentrations.

In July 2025, Expert Geophysics was engaged to conduct a 374 line-kilometer airborne geophysical survey (Mobile MT), which was flown along north-south lines at 100-meter intervals (Figure 1).

The final geophysical data processing has been completed. Sankamap, together with Expert Geophysics and independent geophysical consultants familiar with this type of data, have reviewed the results. The survey highlights several significant geophysical features that will assist in defining the next phase of exploration and drill targeting.

The geophysical models reveal a highly conductive feature that forms a continuous ring-shaped zone flanking a central resistive body. This conductive anomaly appears consistent with a potassic intrusive core or a resistive intrusive complex at depth. Notably, the highest conductivity corresponds with surface zones of advanced argillic and clay-mica alteration (Figure 2).

The conductivity and resistivity highs coincide with a previously mapped annular topographic depression, suggesting potential preferential erosion within the propylitic alteration zone surrounding a core of phyllic-altered rocks (Figure 2). The alignment of these geophysical, geological, and geomorphological features supports a coherent porphyry-style hydrothermal model, with a resistive intrusive core surrounded by conductive alteration halos and erosional depressions marking outer alteration zones.

The integration of these datasets provides a strong 3D framework for ongoing exploration and drill targeting.

About Sankamap Metals Inc.

Sankamap Metals Inc. (CSE: SCU) is a Canadian mineral exploration company dedicated to the discovery and development of high-grade copper and gold deposits through its flagship Oceania Project, located in the South Pacific. The Company’s fully permitted assets are strategically positioned in the Solomon Islands, along a prolific geological trend that hosts major copper-gold deposits; including Newmont’s Lihir Mine, with a resource of 71.9 million ounces of gold¹ (310 Mt containing 23 Moz Au at 2.3 g/t P+P, 520 Mt containing 39 Moz Au at 2.3 g/t indicated, 81 Mt containing 5 Moz Au at 1.9 g/t measured, 61 Mt containing 4.9 Moz Au at 2.3 g/t Inferred).

Exploration is actively advancing at both the Kuma and Fauro properties, part of Sankamap’s Oceania Project in the Solomon Islands. Historical work has already highlighted the mineral potential of both sites, which lie along a highly prospective copper and gold-bearing trend, suggesting the possibility of further, yet-to-be-discovered deposits.

At Kuma, the property is believed to host an underexplored and largely untested porphyry copper-gold (Cu-Au) system. Historical rock chip sampling has returned consistently elevated gold values above 0.5 g/t Au, including a standout sample assaying 11.7% Cu and 13.5 g/t Au²; underscoring the area’s significant potential.

At Fauro, particularly at the Meriguna Target, historical trenching has returned highly encouraging results, including 8.0 meters at 27.95 g/t Au and 14.0 meters at 8.94 g/t Au³. Complementing these results are exceptional grab sample assays, including historical values of up to 173 g/t Au³, along with recent sampling by Sankamap at the Kiovakase Target, which returned numerous high-grade copper values, reaching up to 4.09% Cu. In addition, limited historical shallow drilling intersected 35.0 meters at 2.08 g/t Au³, further underscoring the property’s strong mineral potential and the merit for continued exploration. With a commitment to systematic exploration and a team of experienced professionals, Sankamap aims to unlock the untapped potential of underexplored regions and create substantial value for its shareholders.

Saga Metals Corp. (‘SAGA’ or the ‘Company’) (TSXV: SAGA,OTC:SAGMF) (OTCQB: SAGMF) (FSE: 20H), a North American exploration company advancing critical mineral discoveries, is pleased to confirm the full mobilization of exploration crews and equipment for its highly anticipated major diamond drill program at the 100% owned Radar Titanium-Vanadium-Iron (Ti-V-Fe) Project in southeastern Labrador, Canada.

With site preparations now in the final stages of completion, SAGA is ready to mobilize the rest of its exploration team as drilling is set to commence in early November, targeting the expansion of known oxide mineralization at the Radar project and advancing toward a maiden mineral resource estimate (MRE) over the Trapper Zone.

This major program represents a key milestone in delineating the project’s potential as a strategic domestic source of titanium, vanadium, and high-grade iron ore—minerals critical for defense, aerospace, renewable energy storage, and advanced steel production.

Meanwhile, the Gladiator Drilling crew from Springdale, Newfoundland has been doing final checks and maintenance on the Duralite 800 drill and associated equipment. They are currently packing up and loading the trailers for mobilization.

Figure 4: Gladiator Drilling team finalizing drill maintenance prior to mobilization to the Radar Project

‘The Gladiator crew is busy at the shop today getting ready for the upcoming drill program for Saga Metals in Labrador,’ stated Josh Blundell, CEO of Gladiator Drilling. ‘We are incredibly privileged and excited about being part of the team with Saga Metals and drilling the Trapper zone at the Radar Project. We had great success drilling the Hawkeye zone earlier this year and look forward to doing what we do best once again, putting rocks in the box.’

Drill Program Objectives:

The Phase 1 Trapper Zone drill campaign will target:

• Grade continuity across a 3 km strike length.
• Oxide layering widths and continuity to depths of about 200 metres.
• Integration of structural insights from trenching and drilling into collar orientation and drill design.
• Initial drilling of 1,500-2,500 m in 6-10 holes, each about 250 m in depth will be completed before the December break.
• Test both the North and South sections of the Trapper zone prior to the break in order to fully grasp grade, width and structure prior to initiating the detailed grid and drill sections in 2026 for the purposes of a mineral resource estimate.
• Drilling will be complemented by metallurgical sampling through the winter, with core from both the Hawkeye and Trapper zones undergoing detailed metallurgical testing.

Outlook on Phase 1 of Drilling at the Trapper Zone:

Phase 1 drilling at the Trapper Zone builds on significant milestones from 2025, including:

• Hawkeye drilling success: maiden drill program in early 2025, featuring a 2,209-metre, seven-hole diamond drill campaign across the Hawkeye Zone. The program intersected broad zones of titanomagnetite-rich oxide layering, with cumulative intersections displaying consistent grades of titanium dioxide (TiO ₂ ), vanadium pentoxide (V ₂ O ₅ ) and iron (Fe).
• Metallurgical readiness: Ongoing petrographic and mineralogical studies by Dr. Al Miller confirm those primary magmatic textures favourable for downstream processing.
• Exploration momentum: Expanded property vision with preliminary metallurgical insights and confirmation of large-scale oxide continuity across the Dykes River intrusive complex.

Together, these achievements support SAGA’s strategy of advancing Radar toward resource definition and positioning it as a potential cornerstone critical minerals project in North America.

Advancing the Radar Project

The Radar Property spans 24,175 hectares and hosts the entire Dykes River intrusive complex (~160 km²), a unique position among Western explorers. Geological mapping, geophysics, and trenching have already confirmed oxide layering across more than 20 km of strike length, with mineralization open for expansion.

Vanadiferous titanomagnetite (‘VTM’) mineralization at Radar is comparable to global Fe–Ti–V systems such as Panzhihua (China), Bushveld (South Africa), and Tellnes (Norway), positioning the Project as a potential strategic future supplier of titanium, vanadium, and iron to North American markets.

The Property is well serviced by road access and is conveniently located near the town of Cartwright, Labrador. A compilation of historical aeromagnetic anomalies is overlaid by ground-based geophysics as shown. SAGA has demonstrated the reliability of the regional airborne magnetic surveys after ground-truthing and drilling in the 2024 and 2025 field programs.

‘With the final team members mobilizing and the Gladiator drill rigs ready for the Trapper Zone, we’re on the cusp of transforming Radar from discovery to resource. The 3+ km oxide trend we’ve sampled and trenched is now ready for systematic drilling, and Phase 1 will give us the grade, width, and structural clarity needed to design the full 15,000-metre grid for our maiden MRE in 2026. The camp is built, the core shack is furnished, and the community of Cartwright has been our biggest supporter since day one. This is execution season for SAGA, and we look forward to providing updates along the way,’ stated Michael Garagan, CGO & Director of SAGA .
