Sage Potash Delivers 3.3 Meters of 52.5% KCl at Its Sage Plain Project in Utah

Sage Potash reports high-grade potash assays and plans a resource update within 45 days.

What the company is saying

Sage Potash Corp. is highlighting the successful completion of the Peterson 1 drilling program at its Sage Plain Potash Project in southeast Utah, emphasizing high-grade potash assay results from both the Upper and Lower Cycle 18 beds. The company frames these results as confirming continuity and world-class grade, with three sections exceeding 50.0% KCl and combined grades of 36.3% over 43 feet. CEO Patricio Varas describes the results as transformational and asserts that the project can be advanced rapidly toward production, with expectations for a higher-capacity mine plan than the 300,000 tonnes per year outlined in the September 2025 PEA. The announcement stresses the project's potential scale and purity, referencing less than 1% insoluble material and traces of carnallite. The company is also explicit about next steps, stating that RESPEC LLC has been engaged to deliver an updated NI 43-101 resource estimate within 45 days. The tone is confident and promotional, repeatedly referencing the project's global standing and the U.S. designation of potash as a critical mineral.

What the data suggests

The disclosed assay results from Peterson 1 show 10.8 feet grading 52.5% KCl and 3.3 feet at 52.0% KCl within a 26.6-foot interval averaging 36.1% KCl in the Upper Cycle 18 bed. The Lower Cycle 18 bed returned 10.1 feet at 53.4% KCl within a 16.4-foot interval averaging 36.4% KCl. The combined thickness and grade for Cycle 18 is 36.3% over 43 feet. These grades are among the highest reported globally, and the continuity between Peterson 1 and Johnson 1 (0.62 miles apart) is supported by similar thicknesses and grades, with Johnson 1 returning 23.8 feet at 46.1% KCl (Upper Bed) and 18.0 feet at 35.8% KCl (Lower Bed). The mineralization is described as very clean, with less than 1% insoluble material and traces of carnallite. The company has completed all assays for the recovered core, except for eight one-foot sections reserved for geo-mechanical testing, where gamma ray results were used. An updated NI 43-101 resource estimate is scheduled for delivery in the next 45 days, and the company expects this to support a mine plan larger than the previously contemplated 300,000 tonnes per year. No financial results or production decisions are disclosed; all economic and production projections remain forward-looking.

Analysis

The announcement provides detailed, specific assay results from the Peterson 1 drilling program, including explicit grades, thicknesses, and spatial continuity with the Johnson 1 hole. These are realised, technical facts and represent credible progress for an exploration-stage company. However, the release also contains several forward-looking statements about the project's world-class status, rapid advancement toward production, and the expectation of a higher-capacity mine plan, none of which are yet substantiated by a completed resource estimate or economic study. The claim that the project is 'one of the highest-grade potash resources in the world' is not supported by comparative data. While the next milestone (updated NI 43-101 resource estimate) is expected within 45 days, actual production, economic returns, or development timelines remain unquantified and long-dated. The tone is optimistic and at times promotional, but the technical data disclosed is robust for this stage. No large capital outlay is announced in this release.

Risk flags

• ●Resource expansion and upgrade are not yet realized; the updated NI 43-101 estimate is still pending and may not meet expectations. If the new resource estimate does not materially increase tonnage or grade, the investment case could weaken.
• ●All production and economic projections are forward-looking and depend on subsequent technical studies, permitting, and financing. There is no guarantee that a mine larger than 300,000 tonnes per year will be technically or economically viable.
• ●The company’s narrative relies heavily on the global competitiveness of its grades, but no direct benchmarking data is provided in the release. Without independent comparative analysis, claims of 'world-class' status remain unverified.
• ●Execution risk remains high, as the project is still in the resource definition stage. Advancing to production will require successful completion of a pre-feasibility study, permitting, and significant capital investment, none of which are addressed in this announcement.

Bottom line

Sage Potash has delivered strong assay results from its Peterson 1 drill hole, confirming high-grade, thick potash beds and continuity with the Johnson 1 hole at its Utah project. The company is moving quickly to update its NI 43-101 resource estimate, with delivery expected within 45 days, which could be a key catalyst for re-rating the project’s scale and quality. While the technical results are robust and suggest the potential for a globally competitive deposit, all production and economic outcomes remain speculative until further studies are completed. Investors should watch for the upcoming resource estimate and subsequent technical reports to validate the company’s claims of scale and grade. The most important takeaway is that while the technical foundation is strengthening, the investment case will hinge on the magnitude of the forthcoming resource upgrade and the economics of any future mine plan.

Announcement summary

(TSXV:SAGE, OTCQB:SGPTF) Sage Potash Corp. has announced potash assay results from the Peterson 1 drilling program at its flagship Sage Plain Potash Project in southeast Utah. The Saskatchewan Research Council lab assays returned three high-grade potash sections grading better than 50.0% KCl within the Upper and Lower Cycle 18 potash beds. In the Upper Cycle 18 horizon, 10.8 feet (3.3 m) graded 52.5% KCl and 3.3 feet (1.0 m) graded 52.0% KCl within a 26.6 foot (8.1 m) intersection grading 36.1% KCl. The Lower Cycle 18 bed included a 10.1 foot (3.1 m) section grading 53.4% KCl within a 16.4 foot (5.0 m) intersection grading 36.4% KCl. The combined grade and thickness for Cycle 18 is 36.3% over 43 feet (13.1 m). The Peterson 1 hole is located 0.62 miles (1.0 km) north-northeast of the Johnson 1 hole, confirming continuity and high-grade tenor between the two. The beginning of the Upper Bed of Cycle 18 was encountered at 7,085.6 feet (2,159 m) at Peterson 1, with a dip of approximately 0.8 degrees. A barren halite interval of 42 feet (12.8 m) separates the Upper and Lower Beds. Assays indicate less than 1% insoluble materials and traces of carnallite. At 7,094.5 feet (2,162.4 m), a 13.8 foot (4.22 m) interval grading 45.5% KCl was recovered within a 19.7 foot (5.99 m) intercept grading 39.4% KCl. The Johnson 1 hole previously returned 23.8 feet (7.26 m) at 46.1% KCl in the Upper Bed and 18.0 feet (5.48 m) at 35.8% KCl in the Lower Bed. The Peterson 1 stratigraphic exploration hole was completed on August 4, 2026. Eight one-foot core sections were removed for geo-mechanical testing, with gamma ray results used for potash content in the absence of assays. RESPEC LLC has been engaged to perform a new NI 43-101 resource calculation, with an updated resource estimate planned for delivery in the next 45 days. The September 8, 2025 PEA contemplated a development of 300,000 tonnes per year. The Sage Plain Project is described as containing one of the highest-grade potash resources in the world. Patricio Varas is CEO of Sage Potash. Greg Vogelsang, P.Geo., P.Eng., Vice President Project Development, is the Qualified Person for the release.
