Sage Potash Completes Peterson 1 Drilling; Core and Geophysical Logging Validate Continuity of Cycle 18 Potash Members

Vancouver, British Columbia and Salt Lake City, Utah--(Newsfile Corp. - August 10, 2026) - Sage Potash Corp. (TSXV: SAGE) (OTCQB: SGPTF) ("Sage Potash" or the "Company") is pleased to provide an update following the successful completion of drilling operations at the Peterson 1 well, located at the Company's flagship Sage Plain Potash Project in southeast Utah.

Drilling of the Peterson 1 exploration hole was completed on August 4, 2026, marking a key operational milestone for the project. During an initial onsite geological assessment of the recovered core, the Company confirmed the presence of sylvite mineralization within the two Cycle 18 potash horizons.

To complement the physical core recovery, the Company acquired a comprehensive suite of downhole geophysical logs to characterize subsurface stratigraphy and support interpretation of the targeted potash-bearing intervals. The completed geophysical dataset, received on August 7, 2026, provides further support for the presence of both the Upper and Lower Cycle 18 potash members at Peterson 1. Interpretation of the borehole geophysical responses indicates that the targeted intervals occur at depths and apparent thicknesses consistent with those identified in the previously completed Johnson 1 hole, located approximately 1.2 kilometres south of Peterson 1. Initial analysis of the gamma results from Peterson 1 shows favourable correlation with the high potash grades and thicknesses reported from the Upper and Lower Cycle 18 members in the original Johnson 1 results. Together, these results provide an important geophysical correlation between the two drill holes and further support the Company's interpretation of Cycle 18 stratigraphic continuity across this portion of the Sage Plain Potash Project. When combined with core from the key intervals, the logs and core provide the technical team with increased confidence that the area has the potential to support a significant resource and the Company's envisioned mining operation.

Recovered core from Peterson 1 has been shipped to the Saskatchewan Research Council laboratory in Saskatoon, Saskatchewan, where detailed core logging and assay work will be completed.

Patricio Varas, Chief Executive Officer of Sage Potash, commented:

"We are very pleased with the results of the drill program at the Sage Plain Project," said Patricio Varas, Chief Executive Officer of Sage Potash. "I commend our technical team and drilling contractors for the safe, effective and professional execution of this program, which recovered potash core as planned and anticipated. We look forward to receiving the assay data as Sage focuses on delivering an upsized and upgraded resource estimate."

The Company will continue to provide updates as results become available.
