Eastern Resources has reported strong gold assay results from its maiden rock chip sampling at the Marengo Gold Project, Queensland, with multiple samples exceeding 5 g/t Au and a peak of 12.3 g/t Au, reinforcing the project's shallow high-grade potential.
- All 60 rock chip samples show anomalous gold levels
- 13 samples exceed 5.0 g/t Au, peak at 12.3 g/t Au
- New 1.7km vein system discovered at Reza’s Reef
- High-grade quartz veins confirmed near surface
- Plans underway for detailed mapping and maiden drilling
Strong Gold Grades Confirmed at Marengo
Eastern Resources Limited (ASX:EFE) has unveiled compelling assay results from its initial rock chip sampling at the Marengo Gold Project in Queensland. The company collected 60 samples, all returning anomalous gold levels, with 20 exceeding 1.0 g/t Au and 13 surpassing 5.0 g/t Au. The standout sample hit 12.3 g/t Au, underscoring the project's potential for shallow, high-grade gold mineralisation in quartz veins close to surface.
Expanding Known Vein Systems and New Discoveries
Fieldwork focused on prospects such as One Mile Mountain, Sulphide Shaft, and Seymour’s Reef, covering a 750-hectare zone with extensive historic workings. Notably, the program revealed a previously unmapped vein system named Reza’s Reef, boasting approximately 1.7 kilometres of continuous strike length with veins around 1 metre wide. This discovery adds a significant new target, with 18 samples along the vein consistently returning over 1 ppm Au, suggesting robust mineralisation continuity.
The results build upon historical high-grade rock chip data, which included samples up to 149.8 g/t Au and strong silver and copper associations. Eastern Resources’ Executive Director Myles Fang highlighted the encouraging nature of these assays, stating plans for further mapping, sampling, and maiden drilling to refine targets and advance exploration.
Geochemical Insights and Mineralisation Controls
Assays were conducted at ALS Townsville, targeting gold and a suite of pathfinder elements. The data reveal a strong correlation between gold grades and bismuth, with base metals such as copper serving as broader indicators of mineralised zones. High-grade samples typically exhibit brecciated quartz veins with gossanous textures and cavity-fill oxides of copper and iron, suggesting complex structural controls on mineralisation.
Internationally recognised geologist Dr Gregg Morrison classified the samples based on mineralogical features, noting that the highest grades occur where brecciation and oxide-filled cavities are present. This structural complexity implies that understanding deformation history will be critical to interpreting ore continuity and guiding drilling.
Next Steps and Project Context
Eastern Resources is preparing for a more detailed exploration phase, including further mapping and sampling, particularly along the newly identified Reza’s Reef. Multiple drilling targets have emerged from this program, with plans to initiate a maiden drilling campaign and secure additional exploration permits in the coming months.
The Marengo Gold Project lies within the prolific Queensland mineral belt, approximately 35 kilometres southwest of Bowen and near the 1.1 million ounce Mt Carlton Gold mine. The project area features multiple parallel northwest-trending faults hosting clusters of historic high-grade gold workings over more than 10 square kilometres.
These latest results follow the company’s recent activation of the Marengo farm-in agreement, which gives Eastern Resources the right to earn up to an 80% interest in the project. The combination of historical data and new assays positions Marengo as a promising exploration opportunity within a well-endowed gold region.
Bottom Line?
Eastern Resources’ maiden sampling at Marengo delivers promising high-grade gold results that set the stage for a maiden drilling campaign to test vein continuity and bulk mineralisation potential.
Questions in the middle?
- Will the maiden drilling confirm the continuity of high-grade veins identified by rock chip sampling?
- How will the newly discovered Reza’s Reef vein system influence the overall resource potential?
- What impact might structural complexity have on defining economically viable mineralisation zones?
