Exploration Risks Loom as Sarama Targets Gold at Underexplored Cosmo Belt

Exploration Breakthrough at Cosmo Gold Project

Sarama Resources Ltd has announced the results of its first significant and systematic soil geochemistry survey at the Cosmo Gold Project, located in Western Australia's Laverton Gold District. The survey has delineated extensive gold-in-soil anomalism across approximately 45 kilometres of strike length, spread over eight key prospect areas. This marks a pivotal moment for the project, which had seen limited modern exploration until recently.

The Cosmo Gold Project spans 580 square kilometres and forms part of Sarama's broader 1,000 square kilometre landholding in one of Australia's most prolific gold regions. The newly identified gold trends vary in geological and structural settings, highlighting the project's potential to host multiple styles of gold mineralisation. Notably, the survey recorded a peak soil gold value of 94 parts per billion, a significant indicator of prospective mineralisation beneath the surface.

Geological Context and Survey Methodology

The project lies within the Cosmo Greenstone Belt, an underexplored Archaean greenstone belt characterized by complex geology and significant cover of sand and colluvium, which historically hindered exploration. Sarama leveraged advanced soil sampling techniques, including the LabWest UltraFine+ process developed by CSIRO, which targets ultrafine clay fractions to detect subtle geochemical signatures masked by surface cover.

The survey employed grids spaced between 200 to 800 metres, collecting approximately 5,000 soil samples. The data revealed coherent gold anomalies aligned with major structural features such as the Sefton Shear Zone, a known regional control on gold mineralisation. These findings provide a robust geological framework for prioritising exploration targets.

Key Prospect Areas and Anomalous Trends

Among the eight identified prospects, the Ironbar area features intersecting gold trends extending up to 3.8 kilometres and 2 kilometres, with elevated gold values coinciding with lithological contacts and structural zones. The Warrior-Rockatansky-Pappagallo prospects collectively host a northwest-trending gold anomaly exceeding 7 kilometres in strike length, including the highest soil gold value detected in the survey.

Other notable prospects such as Cheedo-Humungus-Zanetti and Toecutter exhibit broad anomalous zones with footprints up to 1.8 kilometres wide, often beneath sand cover. These extensive anomalies, coupled with their geological setting adjacent to granitoid intrusions and volcanic units, underscore the project's exploration upside.

Strategic Implications and Next Steps

Executive Chairman Andrew Dinning expressed optimism about the results, emphasizing that the scale and number of anomalies align well with Sarama's strategy to unlock value across its Laverton landholdings. The company plans to conduct infill soil geochemistry to refine targets and initiate reconnaissance drilling in areas with sufficient sample density.

This systematic approach, supported by modern geochemical techniques and improved land access, positions Sarama to advance the Cosmo Project from early-stage exploration towards drill-defined targets. The results also highlight the potential for discovering multiple gold mineralisation styles within a largely unexplored greenstone belt.
