Sage Potash mobilizes drill rig at Sage Plain project, Utah

South Jordan, Utah and Vancouver, British Columbia--(Newsfile Corp. - June 24, 2026) - Sage Potash Corp. (TSXV: SAGE) (OTCQB: SGPTF) ("Sage Potash" or the "Company") is pleased to announce that site preparation and mobilization activities for its 2026 drilling program are underway at the Company's flagship Sage Plain Potash Project (the "Project"), located in the Paradox Basin of southeastern Utah, USA. Site preparation is underway, including access road construction, topsoil removal, site levelling, perimeter berm construction, storm water management preparations, and construction of an aggregate platform to create a stable rig base, all in preparation for rig setup activities. Drilling operations are expected to commence approximately two weeks from current site preparations.

Patricio Varas, Chief Executive Officer of Sage Potash Corp. " With potash recently designated as a critical mineral in the United States and approximately 95% of domestic demand supplied through imports, we believe Sage Plain is uniquely positioned to contribute to long-term U.S. fertilizer security. We anticipate the successful completion of this drill program to be a valuable milestone for our shareholders".

The Company will be drilling a 1.275 km (3/4 mile) step out hole to the NNE from the maiden hole from which the Company's current resource is calculated. Historical drillhole data has identified significant potash mineralization within the Cycle 18 Upper and Lower beds at depths of approximately 2,100 metres (6,890 feet): a thickness of 7.26 m (24 ft) at 46% KCl in the Upper bed and a thickness of 5.46 m (18 ft) at 35.8% KCl in the Lower bed. The grades at Sage Plain are amongst the highest tenor or potash grades seen in the USA and indeed the world.

The objective of the current drill program is to intersect the two beds of Cycle 18 in the 1.275 m step-out hole and test for substantially the same grades and thicknesses. Achieving this should allow the Company to expand the inferred resource and upgrade a portion of the overall mineralization to the measured and indicated categories. The Company anticipates releasing an updated resource estimate for Sage Plain in late Q3, 2026.

In addition to confirming potash mineralization, the drilling program will include a comprehensive hydrogeological assessment. The Company plans to conduct targeted Drill Stem Tests ("DSTs") in formations exhibiting sufficient water flow in order to evaluate yield rates and water quality (primarily targeting saline non-potable aquifers) for future solution mining operations. Fluid sampling and detailed water analysis will also be undertaken to support future processing design and cavern development.
