Key Points
- Buffalo Potash (TSXV:BUFF) has completed the final horizontal well at its Disley Initial Production Module, bringing its five-well drilling program to an end.
- All three horizontal wells achieved approximately 95% contact with the target clay seam, with packer systems installed as planned, while the company now prepares for completions, well clean-up and brine circulation.
- The Simply Wall St community narrative estimates fair value at CA$1.06 versus a CA$0.92 share price, implying the shares are 13.2% below that estimate, with the investment case depending heavily on successful development of Disley.
- The next key test is whether Buffalo can translate its completed well infrastructure into effective brine circulation and ultimately first production, targeted for Q1 2027.
The latest Buffalo Potash milestone
Buffalo Potash has completed the third and final horizontal well at the Initial Production Module (IPM) of its Disley potash project in Saskatchewan.
The completed well achieved approximately 95% contact with the targeted basal Belle Plaine clay seam. It joins two other horizontal wells, each also reported to have achieved approximately 95% contact, as well as two vertical wells serving as the source and disposal wells.
That means all five wells required for the IPM are now in place.
The three horizontal wells form the solution mining plane for Buffalo's patented Horizontal Line-Drive (HLD) method. The company has also installed 11-stage packer systems along each horizontal well, which are intended to control the distribution and collection of brine across the mining plane.
The drilling program is therefore complete, but the project has not yet reached production.
From drilling to brine circulation
The next phase involves completing and equipping the wells, cleaning up the wells and packers, and confirming communication between the horizontal wells.
Buffalo then plans to circulate sodium chloride (NaCl) brine through the system. The intended process is to establish pressure communication along the clay seam, clean the seam and then increase brine flow between the injector and producer wells.
For Buffalo, this represents a different type of milestone from drilling. Completing the wells demonstrates that the planned underground infrastructure has been installed. Brine circulation will provide an early test of whether the system operates as intended.
Why the next phase matters for Buffalo Potash investors
The IPM is designed to produce 125,000 tonnes per annum of soluble-grade potash and is intended to provide Buffalo with an initial, lower-capital route toward production.
The company is targeting first production in Q1 2027. It also plans to use the IPM as the first of three planned solution mining facilities at Disley, with the longer-term development plan contemplating up to 1.125 million tonnes of annual potash production across the IPM, Disley East and Disley West.
The latest drilling result therefore removes one development milestone from the near-term path to production. However, several important risks remain.
Most importantly, Buffalo's HLD method has not yet been operated at commercial scale. Successful drilling does not guarantee that brine circulation, dissolution rates, recoveries or production rates will match expectations.
The company's production decision for the IPM also has not been supported by a feasibility study based on mineral reserves. Buffalo explicitly notes that this creates a higher risk of economic and technical failure compared with projects that have established reserves and completed feasibility studies.
Capital requirements are another consideration as Buffalo moves beyond the IPM. The initial module is intended to establish early production and operational experience, while the broader Disley build-out would require substantially more capital.
Most followed narrative
The most followed Simply Wall St community narrative assigns Buffalo Potash a fair value of CA$1.06 per share, compared with a share price of CA$0.92 , implying the shares are approximately 13.2% below the narrative's estimated intrinsic value.
The narrative describes the opportunity as follows:
“Buffalo is trying to mine one of the world's most needed nutrients cheaper, faster and cleaner than the giants.”
Its valuation case is built around several assumptions. These include the successful development of the Disley project, the ability of Buffalo's HLD technology to work commercially, and the potential to scale from the initial 125,000-tonne-per-year module toward the company's larger development plans.
The narrative also highlights the project's preliminary economic assessment, which outlines an after-tax NPV of approximately US$1.1 billion for the full Disley development. It points to the potential for the initial production module to provide an earlier operating milestone and potentially generate cash flow that could support subsequent development.
The current drilling update supports one part of that thesis by showing that the physical foundation for the IPM has been installed broadly as designed. However, it does not yet demonstrate commercial production, operating economics or the scalability of HLD.

What investors may watch next
The focus now moves to execution during the next stages of the IPM.
Investors may watch:
- Whether well completion and clean-up proceed as planned.
- Whether the packer systems communicate effectively across the horizontal wells.
- The results of the initial brine circulation program and the company's ability to establish the intended mining plane.
- Evidence that HLD can achieve sustainable dissolution and production rates at the IPM.
- Progress toward the company's Q1 2027 first-production target.
- How future development is funded and whether additional capital results in material shareholder dilution.
- Any updated technical or economic studies as Buffalo moves toward larger-scale development.
Finishing the drilling campaign marks a significant step forward for Buffalo Potash at its Disley asset.
The upcoming stage will demonstrate if this newly established sub-surface network can deliver successful fluid movement and eventually yield commercial-scale output. Consequently, upcoming operational updates hold considerable weight for shareholders, as advancement toward the early-2027 start date should offer stronger proof of whether the company can successfully commercialize its proprietary extraction process.
