ESGold Strengthens Broken Hill Analogue Theory with Peer-Reviewed University of Studies

Core Viewpoint - ESGold Corp. has validated its Broken Hill-type geological analogue theory for the Montauban Gold-Silver Project through recent seismic imaging results from an Ambient Noise Tomography (ANT) survey, reinforcing the project's exploration potential [1][3][4]. Group 1: Geological Validation - The ANT survey results support the idea that Montauban shares significant genetic and structural similarities with the Broken Hill deposit in New South Wales, Australia [1][5]. - Independent peer-reviewed studies from the University of Calgary and the University of British Columbia confirm that Montauban exhibits structural and geochemical traits akin to Broken Hill, one of the world's largest polymetallic deposits [5][6][13]. - The studies highlight key processes such as sulphide melting and remobilization that enriched and vertically redistributed precious metals, which are critical for deeper discovery [5][14]. Group 2: Exploration Potential - The data shifts Montauban from a historic producer to a high-impact exploration opportunity, indicating a structurally complex, vertically continuous mineral system [3][4]. - ESGold's exploration plan aims to unlock greater potential than previously envisioned, combining academic research with advanced imaging and historical data [4][6]. - The ANT survey has imaged mineralized zones down to 1,200 metres, validating the depth potential of Montauban and supporting the vertical stacking model predicted by academic studies [5][8]. Group 3: Technical Insights - The geological study by Dr. Andrew G. Tomkins at the University of Calgary provides a foundation for understanding Montauban as a complex, metamorphosed VMS system enriched in gold and silver [6][14]. - Key technical parallels between Montauban and Broken Hill include metamorphic grade and sulphide remobilization, confirming the vertical continuity of mineralization [7][10]. - The discovery of rhodonite, a mineral associated with Broken Hill-type systems, adds further weight to the analogue model [12]. Group 4: Next Steps in Development - ESGold is advancing a multi-track strategy for both development and exploration at Montauban, including a low-capex, high-margin tailings recovery strategy to generate near-term cash flow [18][19]. - A refined 3D geological model is being developed to guide upcoming drill targeting, integrating ANT survey data, historical drilling, and structural overlays [19]. - The expansion of the Montauban processing facility and site infrastructure is underway to support the company's near-term production goals [19].
