SAGE POTASH ANNOUNCES COMMENCEMENT OF DRILLING PROGRAM AT SAGE PLAIN POTASH PROJECT

Sage Potash Corp. has commenced a drilling program at its Sage Plain potash project, located in the Paradox basin, southwestern Utah.

The company has engaged Westrock Energy Services (USA) Inc. to manage the drilling program. Westrock is a full-service drilling consultancy with experience spanning more than 2,500 projects across North America. Working in close collaboration with Sage Potash's technical team, Westrock will be responsible for detailed program design, procurement and on-site supervision of all service providers, ensuring a safe, efficient and high-quality drilling operation.

"This drilling program represents a major catalyst for Sage Potash as we move to unlock the full potential of the Sage Plain project," said Pat Varas, chief executive officer of Sage Potash. "Our objective is clear -- expand and upgrade the existing resource base while significantly increasing geological confidence across the project. With strong historical data and a targeted, technically rigorous program, we believe this campaign has the potential to materially advance the project toward development and position Sage as a future low-cost, domestic supplier of potash in North America."

Historical geological data confirms the presence of multiple potash-bearing evaporite cycles in the Paradox basin in southeastern Utah, including the highly prospective Cycle 18 upper and lower beds at depths of approximately 2,100 metres (6,890 feet). The planned drilling program will target these Cycle 18 horizons and include continuous core recovery for geochemical analysis to determine potash ore grades and thickness. The drilling program is designed to confirm the project contains one of the most prospective solution mining targets in the Western United States. With its high purity, solid thickness, high concentration, and low geologic complexity, this drilling program is focused on proving that the Cycle 18 beds can be solution mined competitively with all other North American deposits.

Data collected from the drilling program are expected to advance the project by expanding the project's mineral resource, improving the resource classification, and providing key inputs for continuing engineering and development studies.

RESPEC Company LLC has been retained to deliver comprehensive on-site geological services, including core handling, detailed logging, sampling and preparation for geochemical assaying at SRC Laboratory in Saskatoon, Sask. -- an internationally recognized facility for specialized potash ore analysis. RESPEC will also support all regulatory compliance activities, including permitting and licensing in accordance with State of Utah requirements.

In addition to potash evaluation, the drilling program will include hydrogeological testing to assess potential water supply from shallow to deep aquifers, which is an important component for future solution mining operations.

This drilling program represents a critical step in Sage Potash's staged, technically driven approach to derisking the project and advancing toward higher-confidence economic studies. The results will inform an updated economic evaluation, focused on enhancing geological confidence, optimizing solution mining design, and refining key engineering and cost assumptions, as outlined in the company's National Instrument 43-101 technical report, dated Nov. 6, 2025 (with an effective date of Sept. 8, 2025).

Drilling is expected to commence in mid-Q2 (second quarter) 2026, with assay results and an updated NI 43-101 technical report anticipated in Q3 (third quarter) 2026. With the updated technical report, the company expects to be in a position to launch a feasibility study that will lead the advancement of the Sage Plain resource.

Current resource estimates

The project is underpinned by a significant potash resource located in the Paradox basin, a geologically favourable region with a proven history of solution mining. Inferred resources are derived from Cycle 18's upper and lower potash horizon, some of the highest-quality potash resource globally.

RESPEC, the author of the technical report, expressed confidence in the classification of the resource as an inferred resource using recent and historical well results, because the Paradox basin is very well explored with published maps of the high-grade potash beds, coupled with 2-D seismic showing bedding continuity.

Key resource figures from the technical report:

• Total inferred potash resource: 298 million metric tonnes; a potash resource that potentially supports production of potash and incremental capacity expansion of such production in the future;
• Inferred potash resource:
  • Upper potash bed: 170 million metric tonnes KCl (46.1 per cent);
  • Lower potash bed: 128.2 million metric tonnes KCl (35.8 per cent);
• Flat-lying potash deposits with up to 7.3 meter potash seams with negligible carnallite and insoluble content;
• Potential upper bed potash quantities: 460 million to 530 million metric tonnes (25 to 29 per cent K2O/40 to 46 per cent KCl) within 2,400 to 5,000 metres of Johnson 1 drilled well.
