Geological evaluation of Greenewood deposit
Marmota (ASX: MEU) has finalised its preliminary geological evaluation of the historical Greenewood gold deposit, situated 35km northwest of its prominent Aurora Tank project in South Australia. This review was carried out over a five-month duration by experienced geologist Dr. Kevin Wills, who utilised a comprehensive structural and lithological examination at the site.
The evaluation encompassed the development of cross-sections and a reinterpretation of historical drilling information, which had been largely overlooked. Dr. Wills’ analysis uncovered numerous mineralised zones within the Greenewood system, indicating potential for both shallow and deeper extensions. The geological framework is characterised by sheared and altered metasediments, aligning with other productive gold systems found in the Gawler Craton.
Significantly, the report underscored the existence of high-grade intercepts in past drill holes, which had not been pursued with contemporary exploration methodologies. These discoveries imply that Greenewood may contain economically feasible mineralisation, calling for additional drilling and geophysical investigations.
Marmota’s technical team holds the view that the deposit displays structural resemblances to Aurora Tank, escalating the possibility of a similar discovery. The company is currently assessing the next exploration phase, concentrating on identifying drill targets that could swiftly enhance the project’s resource potential.
Proximity to Aurora Tank and strategic relevance
The Greenewood deposit’s positioning—merely 35km northwest of Marmota’s Aurora Tank project—renders it a highly strategic satellite asset within the company’s extensive exploration domain in the Gawler Craton. This closeness provides substantial logistical and operational advantages, particularly regarding shared infrastructure, workforce, and mobilisation expenses.
From an investor perspective, the chance to develop Greenewood as an auxiliary feed source to Aurora Tank could significantly improve the economics of any prospective production scenario. The opportunity to leverage existing exploration data and geological models from Aurora Tank may also hasten the development timeline for Greenewood, minimising both capital intensity and exploration risk.
Furthermore, the structural similarities between the two deposits—emphasised in the geological analysis—imply a wider mineralised corridor that could encompass various gold-bearing systems. This paves the way for a potential regional-scale discovery model, which would considerably enhance Marmota’s valuation and strategic attractiveness within the junior gold sector.
In light of the current gold price landscape and investor interest in near-term development stories, Greenewood’s proximity to Aurora Tank boosts its strategic significance. It offers Marmota flexibility: whether as an independent project or as part of a hub-and-spoke development model centred on Aurora Tank.
