SAGE POTASH ANNOUNCES SINGLE DERRICK DRILL RIG MOBILIZATION AND SITE PREPARATION AT SAGE PLAIN POTASH PROJECT IN UTAH

Site preparation and mobilization activities for Sage Potash Corp.'s 2026 drilling program are under way at the company's flagship Sage Plain potash project, located in the Paradox basin of southeastern Utah, United States.

Site preparation is under way, 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.

"Receiving final approvals and commencing construction of the drill site is an important event for our team, in anticipation of the start of the drill program and the advancement of the Sage Plain potash project toward its next stage of development," stated J. Patricio Varas, chief executive officer of Sage Potash. "With potash recently designated as a critical mineral in the United States and approximately 95 per cent 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-kilometre (three-quarter mile) stepout hole to the NNE (north-northeast) from the maiden hole from which the company's current resource is calculated.

Historical drill hole data have 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 per cent KCl in the Upper bed and a thickness of 5.46 m (18 ft) at 35.8 per cent KCl in the Lower bed. The grades at Sage Plain are amongst the highest tenor or potash grades seen in the United States 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 stepout 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.
