Sage Potash Corp. (TSXV: SAGE) (OTCQB: SGPTF) has released potash assay results from the Peterson 1 drill hole at its flagship Sage Plain Potash Project in southeast Utah, reporting multiple high-grade intersections exceeding 50% KCl in both the Upper and Lower Cycle 18 potash beds. The results confirm strong grade continuity between Peterson 1 and the previously drilled Johnson 1 hole, located 0.62 miles to the south. The company states the deposit is among the highest-grade potash resources in the world, a claim that may draw significant investor attention given ongoing U.S. critical mineral designations for potash.

Key Points

  • Sage Potash Corp. (TSXV: SAGE) (OTCQB: SGPTF) released drill assay results from the Peterson 1 hole at the Sage Plain Potash Project, Utah
  • Three sections grading above 50% KCl confirmed, including 10.8 feet (3.3 m) of 52.5% KCl and 10.1 feet (3.1 m) of 53.4% KCl
  • Combined Cycle 18 grade of 36.3% KCl over 43 feet (13.1 m); an updated NI 43-101 resource estimate is planned within 45 days
  • Investors may be watching for the updated resource estimate and any subsequent prefeasibility study announcement

Peterson 1 Drill Results Confirm Exceptional Potash Grades at Sage Plain

Assay results from Saskatchewan Research Council laboratories returned three intervals grading above 50% KCl at the Peterson 1 site. The Upper Cycle 18 bed delivered a 26.6-foot (8.1 m) intersection averaging 36.1% KCl, which includes a 10.8-foot (3.3 m) high-grade section at 52.5% KCl and a 3.3-foot (1.0 m) section at 52.0% KCl. The Lower Cycle 18 bed produced a 16.4-foot (5.0 m) intersection at 36.4% KCl, including a 10.1-foot (3.1 m) section at 53.4% KCl. Combined, the full Cycle 18 package delivers a weighted average of 36.3% KCl across 43 feet (13.1 m), according to the release.

Continuity Between Peterson 1 and Johnson 1 Strengthens Deposit Confidence

The Peterson 1 hole was drilled 0.62 miles (1.0 km) north-northeast of the Johnson 1 hole specifically to support resource expansion and to delineate measured and indicated resource categories. The release states that the two holes demonstrate excellent grade and thickness continuity in both the Upper and Lower Cycle 18 beds, with a barren halite interval of approximately 42 feet (12.8 m) separating the beds at Peterson 1 — closely matching the 41-foot (12.5 m) interval at Johnson 1. Assay results also indicate minimal carnallite contamination and less than 1% insoluble materials, reflecting high mineralogical purity across the interval.

Updated NI 43-101 Resource Estimate Planned Within 45 Days

The company has engaged RESPEC LLC — which previously completed a NI 43-101 resource estimate dated September 8, 2025 — to calculate an updated resource incorporating Peterson 1 data. The release states delivery of the updated estimate is planned within 45 days. The disclosure also references a prior Preliminary Economic Assessment contemplating 300,000 tonnes per year of production, noting that the company intends to evaluate a larger-scale mine plan supported by the new resource. The scientific and technical content in the release was reviewed and approved by Greg Vogelsang, P.Geo., P.Eng., the company's qualified person under NI 43-101.

U.S. Critical Mineral Status for Potash Adds Strategic Context

The release notes that the United States has designated potash a critical mineral, and the company highlights global fertiliser-input security as an elevated concern. Sage Potash describes the Sage Plain Project as positioned to contribute to domestic potash supply in this context. Cycle 18 mineralisation is reported to remain open in all directions based on Peterson 1 and Johnson 1 results combined with regional gamma ray and seismic data. The immediate share price impact was not clear from available public information.
