• Effective porosity average 8.8% at Floy Unit 1 Well, 46% higher than existing JORC estimate
• Vuggy porosity logged in diamond core, indicating high porosity for brine storage
• Drill Stem Test at Floy Unit 1 Well showed brine flowing up tubing due to high pressure

Anson Resources Ltd (ASX: ASN) has received an average effective porosity value of 8.8% for the Mississippian Unit historical core from the Green River, which is 46% higher than the porosity value of 6.0% that has been used in the existing JORC resource estimate. The analysis will be used in future JORC resource upgrades and increase the certainty of the Petrel 3D model created by Anson for the Green River Lithium Project. The diamond core showed fracturing and 'vugs' throughout the limestone and dolomite units, demonstrating the high porosity required for the storage of brine. A Drill Stem Test at the Floy Unit 1 Well also showed brine flowing up the tubing by 7,630 feet due to a pressure of 6,046psi and temperature of 156°F (68.9°C). The results from the Floy Unit 1 Well correlate with historical data from nearby wells, indicating similar pressure and porosity characteristics across the project area. This data will be used to refine the JORC resource estimate and exploration target for the Green River Lithium Project.
