Sage Potash secures all permits for Sage Plain drilling program

South Jordan, Utah and Vancouver, British Columbia--(Newsfile Corp. - June 18, 2026) - Sage Potash Corp. (TSXV: SAGE) (OTCQB: SGPTF) ("Sage Potash" or the "Company") is pleased to announce the Company has now received all required approvals and permits from both the local County and the State of Utah to proceed with drilling operations at its Sage Plain project in San Juan County in Utah. Final approvals were granted following a customary site inspection conducted on May 28, 2026, by representatives of the Utah Division of Oil, Gas and Mining ("DOGM"), accompanied by personnel from Sage Potash and its contractors, along with posting of drilling related bonds. As previously announced, the Company has engaged Westrock Energy Services (USA) Inc. to oversee and coordinate all aspects of the drilling program, alongside Drake Well Service Inc. as drilling contractor.

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.

As outlined in the Company's April 7, 2026 news release, the current drilling program is specifically designed to target these potash-bearing horizons and expand and upgrade the resource confidence levels for what management believes to be one of the most prospective and high-grade solution mining potash targets in the United States.

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.

Following completion of coring operations, the open borehole will undergo an extensive suite of geophysical wireline logs. Recovered potash horizon core samples will then be transported to an independent analytical laboratory for detailed geological logging, geochemical sampling, and assaying under strict QA/QC protocols to confirm the grade, continuity, and thickness of the sylvinite mineralization. " Receiving final approvals marks a major milestone in the advancement of the Sage Plain Potash Project, " stated J. Patricio Varas, Chief Executive Officer of Sage Potash Corp. " Our technical team has designed a focused multi-purpose drill program aimed at generating the critical geological and hydrogeological data required to potentially upgrade the resource and advance the Project toward feasibility studies and detailed engineering.

We are confident this program will further demonstrate the quality and scale of the Project while being executed safely and efficiently. " The Company expects to release an updated resource estimate in Q3 2026, incorporating results from the current drilling campaign and historical drilling data. The updated estimate is expected to support the next stage of project advancement, including feasibility studies, detailed engineering, and broader development planning.

The Company and its contractors intend to mobilize for this drill program in short order. About Sage Potash Corp. Sage Potash Corp.
