High-Grade Copper Assays at Greenvale Signal Untapped Exploration Risks

Exceptional Surface Grades Highlight Greenvale's Potential

Superior Resources Limited (ASX, SPQ) has announced outstanding assay results from its Greenvale Project in northeast Queensland, with rock chip and mullock sampling revealing copper grades as high as 46.5%, accompanied by significant gold and silver credits. These results stem from the Halls Reward and Telegraph prospects, reinforcing their status as priority Volcanogenic Massive Sulphide (VMS) copper-gold targets within the company’s portfolio.

The Halls Reward prospect delivered some of the most striking numbers, including assays of 46.5% copper, 6.58 grams per tonne gold, and 24.5 grams per tonne silver. Complementary results from Telegraph, located just 3 kilometres northwest, confirmed high-grade copper values up to 10.99% Cu, further validating the district-scale potential of the Greenvale Project.

Historical Data and Geochemical Anomalies Point to Untapped Extensions

Superior’s exploration builds on historical drilling and soil geochemistry data indicating at least 1.1 kilometres of unmined lode extensions at Halls Reward. Notably, historical drill holes from the 1950s reported copper intersections up to 13.5% Cu over 2.4 metres, underscoring the prospect’s high-grade nature. Soil sampling from the 1990s revealed a large copper anomaly extending well beyond the known workings, suggesting substantial strike continuity and parallel mineralised structures.

At Telegraph, artisanal workings and gossanous outcrops have been sampled, revealing copper-rich pods within structurally controlled shear zones. The presence of secondary copper minerals like malachite and goethite indicates that primary massive sulphide mineralisation likely persists at depth, awaiting confirmation through geophysical surveys and drilling.

Strategic Follow-Up Exploration Planned

Superior is moving swiftly to capitalise on these promising results, with plans for detailed geological mapping, expanded ultra-fine soil geochemistry surveys, and ground-based electromagnetic (EM) geophysical programs designed to delineate subsurface sulphide bodies. These efforts aim to refine drill targets at Halls Reward, Telegraph, and the newly identified Telegraph West prospect, which hosts a significant copper soil anomaly despite being obscured by alluvial cover.

Managing Director Peter Hwang emphasised the significance of these findings, stating that the tenor of copper grades places these prospects among the company’s highest priority targets. The combination of high-grade surface mineralisation and extensive untested extensions positions Greenvale as an emerging district-scale copper-gold project with multiple avenues for resource growth.

Broader Implications for Greenvale and Beyond

These results complement Superior’s broader Greenvale portfolio, which includes large-scale porphyry copper-gold-molybdenum systems at Bottletree and Cockie Creek, as well as other advanced prospects like Wyandotte and One Mile. The Greenvale Project’s geological setting, characterized by volcanic suites prospective for VMS and porphyry-style mineralisation, combined with modern exploration techniques, is unlocking new opportunities in a historically underexplored region.

While the current assays derive from surface sampling and historical data, the upcoming drilling campaigns will be critical to confirming the continuity and true widths of mineralisation at depth. The company’s methodical approach, integrating geochemical, geophysical, and drilling data, aims to build a robust foundation for future resource estimation and development.
