Cautionary statement
: Readers are cautioned that the PEA is preliminary in nature, it includes inferred
mineral resources that are considered too speculative geologically to have economic considerations
applied to them that would enable them to be categorized as mineral reserves, and there is no certainty
that the PEA will be realized. The Company has not defined any mineral reserves for the Project. Mineral
resources are not mineral reserves and do not have demonstrated economic viability.
Vancouver, British Columbia--(Newsfile Corp. - September 22, 2025) - Sage Potash Corp. (TSXV:
SAGE) (OTCQB: SGPTF) ("Sage Potash" or the "Company"), a Canadian company focused on
advancing its Sage Plain Potash Project (the "Project") in the Paradox Basin, Utah, is pleased to
announce the results of a positive Preliminary Economic Assessment ("PEA"). The PEA highlights the
potential for robust project economics, a significant domestic resource base, and growth potential to
establish a scalable and sustainable potash production hub in the United States.
CEO Commentary
Peter Hogendoorn, Chief Executive Officer of Sage Potash, stated:
"This PEA reinforces our conviction that our proposed approach of incremental potash production using
solution mining is a cost effective and low risk strategy to bring in-market potash production on-line in the
US. We expect this approach would allow us to scale up production with cash flow to eventually become
the largest domestic potash supplier in the US market. Currently, the US market imports more than 95
percent of its potash requirements and Sage Potash's goal is to become a supplier of choice in the
United States. The possibility of high margins and scalable expansion suggested by the PEA makes for
a robust asset with stability through a wide range of market conditions."
President Commentary
Tim Mizuno, President and Chief Operating Officer of Sage Potash, added:
"The PEA suggests that we can support the critical agricultural and food security needs of the US market
and deliver meaningful value to shareholders. This is an exceptionally accretive potash project with a
high grade and expansive potash resource. Sage Plain is one of the best potash projects I have seen in
the decades I've spent in the industry and foundational to me joining the Company earlier this year. As
we advance toward production, we expect to further de-risk the Project and build strong partnerships
with farmers and the broader agricultural industry."
PEA Overview

The PEA was completed by Sage Potash in partnership with RESPEC, a leading engineering firm
specializing in integrated technology solutions for mining, energy, infrastructure, water and natural
resources. The PEA includes design of an initial solution-based mining and production unit for an annual
capacity of 300,000 metric tonnes (mt) per year delivering an average of approximately $72 million* per
year in free cash flow once it is fully in production.
The Project is located in San Juan County, Utah, in close proximity to the agricultural areas in the Pacific
Northwest region of the United States. The PEA estimates an inferred mineral resource of 298 million mt
in-situ sylvinite equating to approximately 118 million mt KCl within a 2,400-meter radius of drilled wells.
This radius represents approximately 4 percent of the approximately 26,000 acres of leased mineral
rights. This resource can support multiple phases of production and does not include potential results
from Bureau of Land Management prospecting permits accounting for another 58,780 acres.

The PEA will be filed with Canadian securities regulatory authorities and available on SEDAR+ within 45
days of this announcement. When available, readers are encouraged to read the PEA in the Company's
technical report ("Technical Report") prepared pursuant to National Instrument 43-101 -
Standards of
Disclosure for Mineral Projects
("43-101") in its entirety, including all qualifications, assumptions and
exclusions that relate to the PEA and mineral resource model.
The Technical Report is intended to be
read as a whole, and sections should not be read or relied upon out of context.
ECONOMIC Overview
The economic analysis in the PEA includes the proposed construction of a 300,000 mt per year potash
plant with an initial development plan of 7 caverns and growing to 15 caverns over the first 5 years of
production. Sage Potash plans to complete an already permitted exploration well designed to production
specifications to confirm cavern porosity and flow rates, which will then be converted to the Company's
first production well. Results from this well may result in lowering cavern requirements.
Potash would be produced through an initial 300,000 mt plant accessing the potash resource from the
upper and lower potash horizons of Cycle 18. Processing for recovery of potassium chloride (KCl) uses
triple-effect evaporators, crystallization and fluidized bed dryer for the removal of sodium chloride (NaCl)
and recovery of KCl. This method requires minimal amounts of fresh water when compared to solar
evaporation methods and allows the facility to operate year-round. This approach may be replicated and
scaled in future Project considerations.
With the mine to be located in-market and close to domestic demand, the Project has an economic
advantage relative to other sources of potash located outside of the United States. Additionally,
construction and operation of the proposed mine is de-risked by advanced engineering, advanced
permitting and the inclusion of potash as a critical mineral in the US.
Initial project CapEx of $155 million includes $26 million in contingencies and $16 million in construction
indirect costs (a combined 27% of total project). Over a 20-year Project life, the Project would generate
an unlevered after-tax NPV of $502 million* and 39 percent* IRR. Sustaining CapEx and further cavern
development average approximately $10 million per year equating to approximately $33/mt* over the life
of the Project. Total Project cumulative free cash flow is estimated at $1.26 billion* including total CapEx
over the life of the Project of $327 million*.

OPERATIONS Overview
The Project is strategically located in San Juan County, Utah, in the United States close to agricultural
markets. Utah has been ranked a top US State in terms of business and trade opportunities and mine
development - which has supported the Company's advancement of construction planning and
permitting.
The United States is heavily reliant on potash imports, sourcing more than 95% of its annual demand
from Canada, the former Soviet Union and the Middle East. By developing the Project, Sage Potash has
the opportunity to become a reliable source of potash for American farmers backstopped by low-cost
and high-quality potash production. Additionally, the Pacific Northwest of the United States has
historically commanded a price premium for potash relative to other domestic potash markets.
Over the life of the Project, we expect to produce an annual average gross margin of 68%, generating an
average of $72 million* of annual free cash flow to finance resource and production expansion and
investor returns.

RESOURCE Overview
The Project is underpinned by a significant potash resource located in the Paradox Basin, a geologically
favorable 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.
The Technical Report authors have 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, and the 2D seismic showed bedding continuity.
Inferred total potash resource: 298 million mt; a potash deposit that supports the potential for
production and significant future incremental capacity expansion potential.
Inferred potash resource: 118 million mt KCl (42.1%) and 74.8 million mt K
2
O (26.6%)
Upper Potash Bed: 72 million mt KCl (46.1%) and 45.8 million mt K
2
O (29.1%)
Lower Potash Bed: 46 million mt KCl (35.8%) and 29.0 million mt K
2
O (22.6%)
Flat lying potash deposits with up to 7.3 meter potash seams with virtually no carnallite or insoluble
content.
Potential Upper Bed Potash Quantities: 460-530 million mt (25-29% K
O| 40-46% KCl) within
2,400-5,000 meters of Johnson 1 drilled well.
Next Steps
With the completion of the PEA, which includes favorable environmental and cultural study results, Sage
Potash intends to accelerate efforts towards further delineating the resource by converting inferred
resources to measured and indicated resources, and evaluating many of the Project optimization and
upside opportunities. This includes:
Drilling an already permitted exploration well to confirm final cavern concentrations and flow rates
to complete and submit a solution mine plan, upon which the well will be converted into an initial
production well.
Advancing plant and solution mine engineering and plans to support the issuance of the Large
Mine Operations permit.
Advancing commercial initiatives including potential off-take agreements and industry
partnerships.
Progressing logistics and financing for moving the Company's secured plant and equipment into
Utah.
