Nelson Resources Highlights Four Key Tungsten Exploration Targets at Nevada's Cinnamon Property Near Guardian Metals' Pilot Mountain Project

High-Resolution Airborne Survey Uncovers Extensive Hydrothermal System Beneath Cinnamon Property

Nelson Resources engaged Precision GeoSurveys to perform a high-resolution helicopter-borne geophysical survey over the Cinnamon Property aimed at refining magnetic and radiometric features, mapping intrusive bodies and structural trends, identifying potential skarn-related magnetic anomalies, and assessing trends extending from the Pilot Mountain area. The survey covered 386 line kilometres, including 76 north-south lines and 11 tie lines, flown at 60-meter spacing and approximately 30-meter altitude. Utilizing advanced helicopter-mounted instruments such as the Scintrex CS-3 cesium vapour magnetometer and Medusa gamma spectrometer, the survey delivered detailed resolution critical for detecting subtle mineralisation indicators.

Magnetic survey results reveal a pronounced magnetic anomaly extending 500 meters into Cinnamon from the Gun Metal deposit, aligned with mapped intrusions. A broader magnetic high beneath the property's center is interpreted as a deep-seated hydrothermal system. Radiometric data highlight the hydrothermal and structural framework, with potassium-rich alteration shown by K/Th anomalies, fluid pathways indicated by elevated U/Th anomalies from mobile uranium deposits, and thermal-chemical zoning mapped via U/K ratios identifying high-temperature, potassium-enriched core zones.

Ophir Emerges as Priority Target Supported by Robust Geological Evidence

Integrated data analysis identifies Ophir as the leading near-surface exploration target at Cinnamon. This site exhibits multiple favourable features, including intense epidote-chlorite alteration, iron-oxide geophysical response, suitable limestone host rocks, and a previously unmapped quartz monzonite intrusion confirmed during field reconnaissance. Radiometric and hyperspectral data position Ophir closer to a high-temperature hydrothermal source than other targets, suggesting promising near-surface mineralisation potential.

The convergence of diverse datasets validates Nelson's exploration approach at Cinnamon. Field confirmation of the quartz monzonite intrusion strengthens the geological basis for the geophysical signatures, boosting confidence in target delineation. The combination of alteration intensity, iron-oxide response, and host rock lithology aligns with skarn-style or intrusive-related mineral systems capable of hosting tungsten mineralisation.

NASA Satellite-Based Hyperspectral Analysis Maps Alteration Zones

Nelson commissioned Photosat to perform hyperspectral analysis using NASA's AVIRIS-5 (Airborne Visible/Infrared Imaging Spectrometer, 5th generation) satellite imagery accessed via the Earth Observing System Data and Information System. AVIRIS-5 captures 285 spectral bands across Visible Near Infrared (VNIR) and Short-Wave Infrared (SWIR) ranges, enabling detection and mapping of hydrothermal alteration minerals. Photosat applied its proprietary deep-learning Regional Hyperspectral Targeting tool (R-HET) to identify subtle alteration patterns not visible through conventional interpretation.

This hyperspectral component complements airborne magnetic and radiometric data, allowing Nelson to build a comprehensive 3D model of the Cinnamon Property's hydrothermal system. Employing machine learning on hyperspectral data exemplifies a cutting-edge exploration technique to identify mineralogical signatures linked to mineral systems.

Levant, Malabar, and Serica Targets Represent Leakage Anomalies Over Deeper Hydrothermal System

Beyond Ophir, Nelson identified Levant, Malabar, and Serica targets across Cinnamon's central and eastern areas. These are interpreted as leakage anomalies along structural conduits above a deeper hydrothermal system, manifested as distinct magnetic features consistent with fluid pathways and structural controls for mineral-bearing hydrothermal fluids migrating from a deeper mineralised core.

These leakage anomalies may represent distal expressions of a larger hydrothermal system, offering vectors toward concealed mineralisation. Nelson's upcoming field program includes structural mapping and trace-element geochemistry at these targets to delineate fluid conduits and refine exploration vectors, aiming to characterize the system's structural and geochemical framework and pinpoint prospective mineralisation zones.

Strategic Location Adjacent to Guardian Metals' Pilot Mountain Tungsten Project

The Cinnamon Property is strategically positioned immediately west of Guardian Metal Resources' Pilot Mountain Tungsten Project, which has progressed significantly with a Positive Pre-Feasibility Study announced on 30 June 2026. Pilot Mountain's resource includes Probable Reserves of 11.8 million tonnes at 0.171% WO 3, equating to roughly 20,275 tonnes of contained tungsten, plus 3.5 million ounces of silver at 9.28 g/t. The Desert Scheelite and Garnet deposits, about 2 kilometres west of Cinnamon, contribute to Pilot Mountain's resource base.

Nelson's initial acquisition was informed by U.S. Geological Survey GeoDAWN project data showing a strong magnetic high coinciding with tungsten skarn deposits extending westward from Pilot Mountain into Cinnamon. This proximity to a leading undeveloped tungsten project enhances Cinnamon's exploration potential within a district known for significant tungsten mineralisation. Nelson's geophysical data affirm the property's alignment with the district's geological setting, supporting its prospectivity.

Focused Field Validation Program to Confirm Targets via Prospecting and Sampling

Nelson plans to initiate a detailed field validation program starting with Ophir, emphasizing prospecting and sampling to characterize the hydrothermal system's surface expression and detect mineralisation. Subsequently, structural mapping and trace-element geochemistry will be conducted at Levant, Malabar, and Serica to identify fluid conduits and guide exploration toward concealed mineralisation using elemental pathfinders.

This phased approach systematically tests targets derived from geophysical and hyperspectral data. Prioritizing Ophir concentrates resources on the target with strongest multi-dataset support and surface expression. Follow-up investigations at other targets will enhance understanding of the hydrothermal system and refine identification of the most prospective areas. Nelson's integrated exploration program combines regional geophysical and satellite data with detailed ground geological and geochemical studies.

Favourable Tungsten Market Dynamics and U.S. Critical Mineral Supply Focus

Nelson's Cinnamon exploration aligns with rising tungsten prices and heightened U.S. strategic emphasis on securing domestic critical mineral sources. Tungsten is classified as a critical mineral vital for industrial and defense uses, with global supply dominated by non-allied countries. The U.S. government recognizes tungsten as strategically important, promoting domestic sourcing to reduce import reliance and bolster national security. This policy environment supports domestic tungsten resource development and exploration within the U.S.

Stronger tungsten pricing combined with U.S. critical mineral policy creates a supportive macroeconomic backdrop for Nelson's Nevada exploration. Cinnamon's location adjacent to Guardian Metals' advancing Pilot Mountain Project benefits from existing infrastructure, permitting progress, and demonstrated market interest. Nelson's presence in an active tungsten district with government backing positions the company advantageously for exploration success and future value creation.

Company Overview and Strategic Focus on Tier-One Jurisdictions

Nelson Resources Limited is an Australian mineral exploration firm targeting mineral assets in politically stable, well-regulated, and infrastructure-supported tier-one jurisdictions. Headquartered in Perth, Western Australia, Nelson operates in regions including Nevada, USA. The company emphasizes systematic geological and geophysical exploration combined with rigorous target definition before significant capital deployment.

The Cinnamon Property acquisition and rapid deployment of comprehensive exploration activities reflect Nelson's strategic commitment to prospective mineral assets in established mining districts with proven mineral systems. The swift commissioning of high-resolution airborne surveys post-acquisition demonstrates disciplined investment in advanced geophysical and analytical techniques to define targets for ground follow-up. Nelson's operational base in Nevada and focus on tungsten-prospective Cinnamon position it to capitalize on emerging U.S. domestic tungsten supply opportunities driven by policy and market trends.

Magnetic High Interpreted as Deep Hydrothermal Center with Skarn Mineralisation Potential

Nelson's integrated geophysical interpretation identifies a broad magnetic high beneath Cinnamon's central area, interpreted as a deep-seated hydrothermal system. Geological assessment supports this as an intrusive-related hydrothermal system capable of producing skarn mineralisation through contact metamorphism between igneous intrusions and carbonate host rocks. Ophir's favourable limestone host rocks, confirmed quartz monzonite intrusion, and strong magnetic anomaly extending from the Gun Metal deposit direction corroborate a district-scale mineral system.

This magnetic high is a key exploration signature indicating a mineralised hydrothermal center or mineral-bearing body at depth. Its regional scale and continuity with known mineralisation at Pilot Mountain suggest the four targets flank or overlay potential deep hydrothermal centers and skarn mineralisation. Nelson's systematic field validation program aims to test this model and locate mineralisation associated with the interpreted hydrothermal system.
