Eastern Resources Limited (EFE) has completed its inaugural reconnaissance fieldwork at the Marengo Gold project, situated about 45 kilometres southeast of the 1.1 million ounce Mt Carlton Gold mine in Queensland. The exploration initiative uncovered numerous historic workings and over 200 quartz occurrences, with 60 rock chip samples submitted for laboratory testing. Following the quarter's end in July 2026, assay outcomes revealed promising gold concentrations, including two samples surpassing 10 parts per million gold.

Marengo Gold Project Situated in Queensland's Prolific Gold Belt
The Marengo Gold project is located within one of Australia's most productive gold regions, approximately 45 kilometres southeast of the 1.1 million ounce Mt Carlton Gold mine. It lies in the prolific Queensland mineral belt, home to significant gold deposits including Pajingo (2.7 million ounces), Ravenswood (4.8 million ounces), Mount Wright (1 million ounces), Mount Leyshon (3.8 million ounces), and Charters Towers (6.6 million ounces). This geological setting underscores the area's strong potential for major gold discoveries.
Classified as a high-level Intrusion Related Gold Copper System, the Marengo project encompasses the historic Marengo Goldfield, known for shallow, high-grade gold-bearing quartz veins. Structural controls linked to an intrusive source at depth and evidence of a late magmatic hydrothermal mineralised system form the basis of the company's exploration strategy, targeting both shallow vein-hosted and larger porphyry epithermal bulk mineralisation.
Initial Fieldwork Targets Three Key Prospect Areas with Historic Workings
Eastern Resources' maiden reconnaissance focused on One Mile Mountain, Sulphide Shaft, and Seymour's Reef prospects, which contain over 50% of known historic workings spanning more than 3 kilometres of potential strike length. Systematic mapping and sampling aimed to assess the potential for shallow, high-grade gold-bearing quartz veins, building on historical gold grades from rock samples.
The program confirmed nearly all historic workings, uncovered numerous unnamed and unmarked workings, and identified over 200 isolated quartz localities within a 750-hectare target area. This zone trends northwest over 9 kilometres in length and up to 2 kilometres wide. Fieldwork also discovered a promising north-northeast oriented vein system at Reza's Reef prospect, with approximately 1.7 kilometres of continuous strike length and an estimated 1-metre width, accompanied by up to two parallel veins.
Geophysical Surveys Highlight Structurally Controlled Mineralisation
Ground magnetics and Induced Polarisation surveys by BGM revealed that the three prospect areas experienced significant structural deformation. Faults identified are believed to have facilitated emplacement and deposition of high-grade, structurally controlled mineralisation, supporting the company's view that structural features govern gold distribution.
Field observations confirmed complex structural patterns, with most veining striking close to north-south (010 to 350 degrees) and variable lateral extents. Veining trends at Flat Reef, Homeward Bound, and Tiger's Mate include northwest-southeast and northeast-southwest orientations, which appear to post-date and potentially cut the main north-south vein set. These findings suggest mineralisation relates to a deep intrusive source with a late magmatic hydrothermal system, warranting further investigation.
July 2026 Assay Results Reveal Strong Gold Grades and Pathfinder Elements
In July 2026, assay results from 60 rock chip samples collected in May confirmed substantial gold mineralisation potential at Marengo, encompassing shallow high-grade quartz veins and larger porphyry epithermal bulk targets. Samples were analysed at ALS Townsville using fire assay (AA26) for gold and ME-ICP61 for pathfinder elements. Fifty-four samples exceeded 0.1 ppm gold, indicating widespread mineralisation.
Notably, two samples surpassed 10 ppm gold, with a maximum of 12.3 ppm. Ten samples exceeded 5 ppm, another ten surpassed 1 ppm, six were above 0.5 ppm, and sixteen ranged between 0.1 and 0.5 ppm gold. Pathfinder elements included silver, bismuth, molybdenum, tungsten, sulphur, copper, and lead, with silver and bismuth showing the strongest correlation to gold. These results confirm the high-grade nature of quartz vein-hosted gold-silver mineralisation, particularly along Reza's Reef, which consistently returned over 1 ppm gold, marking it as a prime target for detailed exploration.
Reza's Reef Discovery and Pathfinder Element Insights Shape Exploration Plans
The newly identified Reza's Reef vein system extends about 1.7 kilometres north-northeast between One Mile Mountain and Homeward Bound prospects, with an estimated 1-metre width and up to two parallel veins. Eighteen samples were collected along this previously unmapped vein, providing comprehensive coverage.
Pathfinder element analysis indicates high-grade gold is strongly associated with bismuth, while lower-grade gold correlates with base metals, especially copper. This suggests base metals guide general gold enrichment zones, while bismuth signals high-grade mineralisation. These insights will direct future sampling and target generation, prioritising Reza's Reef for detailed follow-up exploration given its consistent gold grades, favourable structural setting, and pathfinder signatures.
Nowa Nowa Iron Project Advances Environmental Effects Assessment in Victoria
During the June 2026 quarter, Eastern Resources progressed the Environmental Effects Assessment approval process for the Nowa Nowa Iron project in Victoria. This comprehensive permitting process covers all planning and operating licences needed for development and operation. The project comprises exploration licence EL006183 and retention licence RL006488, both held by Gippsland Iron Pty Ltd with EFE retaining 100% interest. No specific approval timelines were disclosed.
The company noted the nearby Mt Carlton gold mine’s restart, located about 45 kilometres northwest of Marengo, as a positive indicator for the region’s mining outlook. This operational resumption may reflect improving market conditions and bolster confidence in Queensland’s mineral prospects. Eastern Resources’ focus on advancing Nowa Nowa’s environmental approvals underscores its commitment to progressing this development-stage asset.
Minimal Activity at Nowa Nowa Copper and Lithium Projects During Quarter
No exploration work was conducted on the Nowa Nowa Copper project or the lithium projects, including Trigg Hill and Lepidolite Hill, during the June 2026 quarter. These assets remain part of the company’s portfolio but were not actively developed, reflecting a strategic focus on Marengo Gold fieldwork and the Nowa Nowa Iron Environmental Effects Assessment.
This shift in activity highlights resource allocation toward higher-priority initiatives. The company is also reviewing new project opportunities and engaging in commercial discussions for potential acquisitions, indicating an active approach to strengthening its project portfolio.
Financial Position and Related Party Payments Indicate Operational Phase
At the end of the June 2026 quarter, Eastern Resources reported approximately $3.27 million in cash and cash equivalents. Related party payments totaled $125,000 (excluding GST) for directors’ fees and consulting services, reflecting standard commercial remuneration. These figures suggest sufficient liquidity to support current exploration and administrative activities, though funding duration depends on exploration pace and costs.
The financial data indicate the company is in early to mid-stage exploration, focusing capital expenditure on fieldwork and evaluation rather than development. Management continues to assess strategic options, including potential capital raising, to support accelerated exploration or environmental approvals.
Regional Market Dynamics and Sector Context Favor Gold Exploration in Queensland
Eastern Resources’ Marengo Gold project progress and positive assay results occur amid a supportive regional environment. The nearby Mt Carlton gold mine’s restart signals confidence in Queensland’s gold sector and validates the economic viability of major deposits under current conditions. This operational milestone reinforces the district’s geological prospectivity and commercial appeal.
Queensland’s mineral belt boasts cumulative historical production and resources exceeding 25 million ounces of gold across multiple major camps. This proven track record underpins confidence in ongoing exploration investments. The presence of large deposits with similar geology and proximity to operating mines suggests continued opportunity for discovery and development in the region.
