Nelson Resources has identified a promising copper-gold target at its Cinnamon Property in Nevada, delivering rock-chip samples with significant grades and outlining a clear path for advancing both copper-gold and tungsten prospects.
- High-grade copper-gold rock chips at Sheba target
- Epithermal mineralisation linked to intrusive hydrothermal system
- Ophir target prioritised for near-surface tungsten skarn
- Cinnamon Property strategically adjacent to Pilot Mountain Project
- Follow-up mapping and sampling planned to refine targets
Sheba Target Delivers Immediate High-Grade Assays
Nelson Resources (ASX:NES) has swiftly turned its Cinnamon Property in Nevada into a hotspot for copper-gold exploration with the discovery of the Sheba target. Reconnaissance rock-chip sampling within a strong magnetic anomaly on the footwall of the Luning-Fencemaker Thrust yielded standout results including 1.95 g/t gold, 40.3 g/t silver, 0.287% copper, and a notable 6.63% lead. These assays confirm a robust epithermal signature, supported by elevated pathfinder elements such as arsenic, antimony, mercury, and cadmium, indicative of a shallow-to-distal hydrothermal environment.
Integrated Geophysics and Alteration Mapping Define Hydrothermal System
The Sheba and neighbouring Ophir targets are interpreted as components of a broad intrusive-related hydrothermal system. Nelson’s integration of high-resolution airborne magnetic and radiometric surveys with hyperspectral AVIRIS alteration mapping has delineated intense potassic, epidote-chlorite, and muscovite alteration zones aligned along a major regional thrust fault. This structural corridor appears to channel mineralising fluids, creating favourable conditions for both epithermal copper-gold and tungsten skarn mineralisation.
Ophir Emerges as Priority Tungsten Skarn Target
While Sheba grabs attention for its precious and base metals, Ophir stands out as a near-surface tungsten target. Situated immediately adjacent to Sheba, Ophir exhibits intense epidote-chlorite alteration, a strong iron-oxide hyperspectral footprint, and favourable limestone host rocks. Crucially, a newly mapped quartz monzonite intrusion has been identified here, interpreted as a Late Cretaceous intrusive stock similar to those hosting tungsten skarns at the adjoining Pilot Mountain Project. This proximity underscores the strategic value of Cinnamon, which sits just west of one of the United States’ most advanced undeveloped tungsten projects.
Strategic Location and Exploration Model Support Prospectivity
The Cinnamon Property’s geological setting aligns closely with the known tungsten skarn deposits at Pilot Mountain, where skarn mineralisation occurs along contacts between quartz monzonite intrusions and Luning Formation limestone. Nelson’s airborne magnetic data reveals previously unmapped intrusive stocks beneath Cinnamon, bolstering the potential for concealed tungsten mineralisation. The company’s exploration model targets intrusive-related hydrothermal systems hosting polymetallic mineralisation, including copper, gold, tungsten, silver, zinc, and lead.
Follow-Up Work to Drive Target Refinement
Nelson plans immediate detailed prospecting, geological mapping, and systematic rock-chip sampling at both Sheba and Ophir to refine the understanding of these promising zones. Additional structural and trace-element geochemical work will focus on other priority areas; Levant, Malabar, and Serica; to identify fluid pathways and vector toward deeper mineralisation. These steps aim to rapidly advance the copper-gold and tungsten opportunities and lay the groundwork for potential resource delineation.
Bottom Line?
Nelson Resources’ Cinnamon Property has transitioned from acquisition to discovery, but the leap from rock chips to resources will hinge on upcoming detailed exploration and drilling.
Questions in the middle?
- Will follow-up sampling confirm continuity and extent of the high-grade copper-gold mineralisation at Sheba?
- Can Ophir’s tungsten skarn potential be validated through drilling, given its proximity to Pilot Mountain?
- How will Nelson prioritise exploration capital between polymetallic targets amid evolving assay results?
