Fieldwork Uncovers Promising Gold-Silver System at Sascha Marcelina
Pursuit Minerals Ltd (ASX:PUR) has launched geological mapping and Induced Polarisation (IP) geophysics at its Sascha Marcelina Gold-Silver Project in Argentina’s Santa Cruz Province, unveiling a substantial mineralised system. Early field observations reveal multiple structurally controlled vein corridors with extensive quartz-chalcedony veining and silicified breccias, hallmark signs of a preserved hydrothermal system. These findings set the stage for a maiden drilling campaign aimed at testing the scale and continuity of mineralisation at depth.
The company’s Managing Director Aaron Revelle described the initial mapping as a "key step" in advancing a "highly compelling exploration opportunity," noting textures and alteration consistent with productive epithermal systems. The IP survey, designed to detect sulphide-bearing zones beneath surface cover, is progressing systematically across priority targets including Sascha Main and Valdivia Brechón. This integrated approach is expected to sharpen drill targeting ahead of upcoming operations.
Geological Mapping Highlights Structural Controls and Hydrothermal Activity
Mapping has covered about 55% of priority areas, revealing a mineralised system hosted within Jurassic Chon Aike volcanic sequences. NW–SE trending fault systems appear to channel hydrothermal fluids, forming multiple sub-parallel corridors. At Sascha Main, extensive outcropping quartz chalcedony veins exhibit epithermal textures such as colloform banding and lattice-bladed calcite pseudomorphs, indicative of fluid boiling and phase separation, processes linked to precious metal deposition.
Similarly, the Valdivia Brechón target shows fault-controlled silicified breccias and chalcedony veins within altered ignimbrites, with oxidation and cataclastic textures supporting a district-scale hydrothermal system. Mineralisation exposed near the erosional surface beneath Tertiary cover suggests potential for deeper extensions. These observations align with Pursuit’s model of a vertically extensive mineralised district with prospective high-grade zones at depth.
Induced Polarisation Survey to Refine Subsurface Targets
The ongoing IP survey focuses on the key NW–SE structural corridors, aiming to detect chargeability anomalies linked to sulphide mineralisation not visible at surface. Survey lines are strategically spaced to provide detailed resolution across Sascha Main, Valdivia Brechón, and the broader Marcelina corridor. Data integration with geological mapping will refine structural interpretations and prioritise drill targets.
This systematic geophysical campaign is a critical precursor to the maiden drilling program, which will test the depth, scale, and continuity of the mineralised system. The combined geological and geophysical dataset is expected to enhance targeting confidence and deliver a focused, high-impact drill campaign.
Advancing Exploration and Development Across Argentina Portfolio
Alongside Sascha Marcelina, Pursuit is progressing its Rio Grande Sur Lithium Project, with drilling preparations underway at the Mito tenement following significant depth extensions identified through CSAMT reprocessing. This complements the gold-silver exploration and positions the company with a diversified pipeline of near-term catalysts. The lithium project is advancing with camp construction and drill rig mobilisation, aiming to expand resource potential and support pilot plant operations.
The company’s recent capital raising efforts, including a $4.46 million tranche completed earlier this year, underpin these exploration and development activities, providing financial flexibility to accelerate drilling and technical studies across its Argentine assets $4.46M tranche completed. Pursuit’s integrated approach across precious metals and lithium projects reflects a strategic effort to unlock value in a resource-rich region.
Bottom Line?
Pursuit’s integrated geological and geophysical work at Sascha Marcelina sets a strong foundation for a maiden drill campaign that could reveal significant gold-silver mineralisation at depth.
Questions in the middle?
- Will the maiden drilling confirm the scale and grade continuity suggested by surface mapping and IP data?
- How might deeper mineralisation at Sascha Marcelina influence Pursuit’s resource estimates and project valuation?
- What are the timelines and expected milestones for assay results and subsequent development decisions?
