[{"type":"text","content":" Vancouver, British Columbia--(Newsfile Corp. - March 20, 2025) - ESGold Corp. (CSE: ESAU) (OTCQB: SEKZF) (FSE: Z7D) (\"ESGold\" or the \"Company\") is pleased to announce the identification of rhodonite, a manganese silicate mineral (MnSiO₃), at its Montauban Project. The discovery was made as part of a sampling program around the historical Montauban deposit and may hold geological significance, as it aligns Montauban with the signature mineralogy of Broken Hill-type (BHT) deposits. Rhodonite: A Known Marker at Some High-Grade Sulphide Deposits Rhodonite is a manganese-rich mineral that forms under high-temperature, low-pressure metamorphic conditions. While it is not a primary ore mineral, its presence is often indicative of structural deformation and remobilization, processes that can enhance the concentration of valuable metals such as lead, zinc, silver, and gold. In BHT deposits, rhodonite is found in close association with argentiferous galena (silver-rich lead sulfide), sphalerite (zinc sulfide), and pyrrhotite (iron sulfide). Its occurrence at Montauban suggests that similar geological processes may have influenced the mineralization underlying the property, reinforcing the potential for previously unrecognized high-grade mineralization at depth. Geological Context at Montauban Rhodonite is rare in typical volcanogenic massive sulfide (VMS) deposits but is a distinguishing feature of some high-grade lead-zinc-silver systems. The mineral is typically associated with manganese enrichment, which is not a dominant characteristic of most VMS deposits but is present in BHT systems. The presence of rhodonite indicates that deformation and remobilization may have been contributing factors to the mineralization model at Montauban, and that historical exploration may not have fully tested the deposit's potential. Current exploration programs, including the ongoing Ambient Noise Tomography (ANT) survey, aim to model the subsurface mineralized structures and define potential high-priority drill targets. Implications for Ongoing Exploration The discovery of rhodonite at Montauban supports the hypothesis that the deposit may host deeper, high-grade zones beyond the historically mined near-surface material. Given that historical drill programs primarily tested depths of less than 50 m, the ongoing ANT survey will play ...
