Buffalo Potash Corporation (TSXV: BUFF | OTCQB: BLPTF | FSE: VU5) has received approval from the Saskatchewan Ministry of Environment to construct and operate the Initial Production Module at its Disley Project, marking what the company describes as the final key regulatory hurdle before it can complete construction and begin operations. The approval, issued under Permit No. PC26-153, follows a ministerial determination in September 2026 that the module does not require a full Environmental Impact Assessment. With drilling and completions already finished and equipping underway, the company continues to target first potash production in Q1 2027, a milestone investors will be closely watching.

Key Points

  • Buffalo Potash Corporation (TSXV: BUFF | OTCQB: BLPTF | FSE: VU5)
  • Saskatchewan Ministry of Environment issued Permit No. PC26-153, authorising construction and operation of the Disley Initial Production Module
  • The IPM is designed to produce 125,000 tonnes per annum of soluble-grade potash; the permit is effective to April 30, 2027, with provision for extension
  • Investors will be watching the commencement of brine circulation and progress toward the Q1 2027 first-production target

Saskatchewan Ministry of Environment Issues Permit No. PC26-153 for Disley IPM

The approval, issued pursuant to The Environmental Management and Protection Act, 2010, authorises a broad scope of surface infrastructure at the Disley site, including above-ground and buried pipelines, brine and water storage tanks, pumps, processing equipment, electrical and utility infrastructure, secondary containment systems, modular buildings, roads, and stormwater management works. The permit is subject to conditions, including Ministry approval of a Site Characterisation and Groundwater Monitoring Plan and compliance with applicable air quality requirements before processing equipment is operated. Financial assurance acceptable to the Ministry must also be maintained throughout the permit period.

Disley IPM Development Phases and the Path to Brine Circulation

Buffalo Potash reports that source and disposal well drilling and its Horizontal Line-Drive drilling program are both complete, with equipping now underway. The company states that the approval enables surface construction to advance in parallel with preparations for Phase 3 — brine circulation — which is designed to establish communication between injector and producer wells along the clay seam and develop the mining plane that would feed the IPM processing facility. The permit applies solely to the IPM; any subsequent development at Disley East or Disley West will require separate regulatory approval from the Ministry of Environment.

Disley Project Scale and PEA Economics at Full Build-Out

The IPM is the first of three planned solution mining facilities at the Disley Project, located approximately 50 kilometres northwest of Regina across 10,610 hectares. At full build-out — comprising the IPM, Disley East, and Disley West — the project is contemplated to produce up to 1,125,000 tonnes per annum of potash. A preliminary economic assessment published in May 2026 estimated an after-tax net present value of US$1.1 billion at an 8% discount rate and an internal rate of return of 30%. The PEA also estimates a standalone IPM payback period of approximately 12 months from the start of production. The production decision is not based on a feasibility study, and no mineral reserves have been established, which the company acknowledges carries elevated economic and technical risk.
