Anson Intersects Mississippian Horizon at Mt Fuel Well

Key points

  • Anson intersected the Mississippian horizon at 9,189ft in the Mt Fuel-Skyline Geyser well
  • Samples collected from the Mississippian Units showed inflow of fluids and chlorides
  • Brine samples to be collected to increase the JORC resource by converting the Exploration Target

Full summary

Anson Resources Limited (ASX: ASN) has intersected the Mississippian target horizon at 9,189ft in the re-entry drilling program of the Mt Fuel-Skyline Geyser 1-25 well at its Green River Lithium Project in south-eastern Utah, USA. Drilling through the top of the Mississippian Units, it was detected that a small amount of chloride had entered the oil based muds. Samples were collected and fluid (water and brine) was separated from the muds to be assayed. The aim of the program is to confirm lithium rich brines are located in the target horizons, which will be used to increase the interpreted JORC Resource surrounding the Bosydaba#1 well 12km to the north, by converting the large Exploration Target into Indicated and Inferred Resources. The targeted Mississippian horizon has recorded supersaturated brines intercepted during historical oil and gas drilling, with the one assayed sample showing salt concentrations similar to that of the recently drilled Bosydaba#1 well. Anson plans to collect brine samples from the Mississippian Units to further evaluate the lithium potential of the area.
