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 a crucial role in determining the full extent of the mineralized system.
“The identification of rhodonite at Montauban provides important geological context for our exploration efforts,” said André Gauthier, P.Geo., “In many high-grade lead-zinc-silver deposits, including Broken Hill, rhodonite has been recognized as a key indicator mineral associated with structurally controlled mineralization. This finding strengthens our understanding of Montauban’s geology and will help guide future exploration efforts, particularly in targeting deeper, untested zones.”
The Company would like to note that mineralogical observations are preliminary, and the interpretations based on them are conceptual. There is no certainty that further exploration or detailed studies will substantiate these preliminary observations or that the project’s geological characteristics or mineralization will be economically viable.
Next Steps
Completion of the ANT Survey – Results from the 3D subsurface imaging program will provide insight into the scale of mineralized structures at Montauban.Follow-Up Sampling & Structural Analysis – Additional sampling and structural mapping will further define the extent of rhodonite occurrences and their association with economic mineralization.Drill Target Refinement – Pending the results of the ANT survey and additional geochemical work, ESGold will refine its drill targeting to test deeper mineralized zones.
The identification of rhodonite at Montauban marks an important step in refining the geological model of the deposit. The Company continues to integrate modern exploration technologies to unlock the full potential of the project, leveraging systematic geophysical and geochemical analysis.
