Unlocking Hidden Gold: Sarama’s Exploration Push Faces Land Access and Geological Challenges

Exploration Revival at Cosmo Gold Project

Sarama Resources Ltd (ASX:SRR) has initiated a landmark exploration campaign at its majority-owned Cosmo Gold Project in Western Australia’s Eastern Goldfields. This multi-stage soil geochemistry program marks the first major systematic exploration effort on the 580km² project in several decades, aiming to generate high-quality drill targets in a region historically overlooked due to land access constraints.

Located approximately 85km northeast of Laverton and near the prolific Gruyere Gold Mine, the Cosmo Project covers a largely underexplored greenstone belt with over 50km of strike length. Sarama’s recent acquisition of a controlling interest in Cosmo, combined with a pending majority stake in the adjacent Mt Venn Project, positions the company with a commanding 1,000km² exploration footprint capturing more than 100km of strike in this highly prospective gold district.

Advanced Soil Sampling to Unlock Hidden Targets

The cornerstone of Sarama’s strategy is a large-scale soil geochemistry program employing the UltraFine+™ analytical process developed by CSIRO. This cutting-edge technique targets ultrafine soil fractions, enabling detection of subtle gold anomalies beneath transported cover and complex regolith, conditions that have historically hampered exploration in the area.

Sampling grids will vary from broad 800m by 100m spacing to tighter 200m by 100m grids over priority zones identified through recent airborne geophysical interpretations. These zones include major structural corridors such as the Sefton Structural Corridor and lithological contacts near internal granitic intrusions, both considered favorable for gold mineralization.

Historical surface grab samples within the project have returned impressive gold grades up to 52g/t Au, underscoring the prospectivity of the region. Sarama’s field crews are already mobilized, with initial samples expected to be submitted for analysis imminently.

Strategic Positioning in Laverton Gold District

Andrew Dinning, Sarama’s President and Executive Chairman, highlighted the significance of the exploration restart: "Cosmo is genuinely underexplored and has all the geological ingredients to generate a discovery. Our team brings experience from multi-million ounce discoveries in Africa, and we are excited to apply that expertise here." He further emphasized the strategic value of combining Cosmo with the Mt Venn Project to create a dominant exploration position in the Laverton Gold District.

The Cosmo Greenstone Belt’s geology features a mix of metabasalt, ultramafic, and felsic volcanic rocks, with major shear zones and granitoid intrusions that provide structural and lithological controls for gold mineralization. Approximately 75% of the project area is covered by transported sediments, making modern geochemical techniques essential for effective exploration.

Looking Ahead: From Soil Sampling to Drilling

Sarama’s exploration roadmap includes broad-scale soil sampling to build a foundational geochemical dataset, followed by detailed mapping, airborne geophysics infill, and targeted drilling programs. Historical reconnaissance drilling was limited and of low reliability, underscoring the need for Sarama’s systematic approach.

With land access issues recently resolved and robust native title agreements in place, Sarama is well-positioned to advance exploration efficiently. The company’s use of modern analytical methods and experienced personnel aims to unlock the latent potential of one of Western Australia’s last underexplored greenstone belts.
