High Grade Lithium Brine: Surpassing local records. Shallow pool brine sample assayed at 918 mg/L Lithium.

Significant Resource Potential: TEM surveys outlined a 22.7 billion m3 brine aquifer with a cut off of <6.5ohm.

Premium Positioning: Located near the Chinese border enabling easy access to infrastructure, and future buyers.

District Scale: Geologically similar to the Andean (Argentina, Bolivia, and Chile) Lithium Triangle, demonstrating district scale potential.

In 2022, Osiris One’s exploration team delivered a comprehensive exploration program at Urgakh Naran, completing nearly 100 kilometres of transient electromagnetic (TEM) surveying that identified strong conductivity and low resistivity signatures consistent with a significant brine aquifer.

This work included an initial shallow auger drilling program comprising 73 holes, an 82 line-kilometre TEM survey - that defined a large low-resistivity zone -, and a subsequent 16 line-kilometre follow-up TEM survey - that confirmed the continuity of this zone.

Collectively, the TEM data outlined a brine aquifer of approximately 22.7 billion cubic metres using a <6.5 ohm-m resistivity cutoff, drawing clear geological parallels with established assets in the Lithium Triangle.

The program was further advanced through the successful completion of three lithological diamond core drill holes for a total depth of 954 metres, returning average lithium grades exceeding 320 ppm over intercepts of approximately 100 metres.

Notable results include:

  • UNDH-01: 123m at 278ppm lithium from 122m, with maximum lithium reported at 832ppm over 2m;

  • UNDH-02: 100m at 362ppm lithium from 65m, with maximum lithium at 601ppm over 2m; and

  • UNDH-03: 71.4m at 360ppm lithium from 3.6m with maximum lithium at 911ppm over 2m.
