Buffalo Potash Corp.

The Disley Project

Located in the heart of Saskatchewan’s potash production region adjacent some of the most prolific potash solution mines globally.

Located in the World’s Best Jurisdiction for Potash Production

The Elk Point Basin is one of the world’s most significant potash provinces, covering roughly 1.2 million square kilometers of sedimentary geology that is rich in potash-bearing salt. It is considered the largest source of potash on the planet, and by some assessments may contain 40% to more than 50% of the world’s total potash resources. Since mining began in 1962, companies operating in the basin have produced more than 1.5 trillion metric tons of ore, yielding 605 million tonnes of potash (KCl) with an estimated total value well in excess of US$70 trillion, underscoring the basin’s global importance to fertilizer supply and food security.

Confirmation Phase

Buffalo is advancing a series of operational activities to assess the Disley Project. The Confirmation Phase is designed to inform a preliminary economic assessment of the long-term viability of a selective solution potash mining operation on the property using the Company’s patented Horizontal Line-Drive (“HLD”) mining system, subject to the results of ongoing technical work.

Key objectives for the Confirmation Phase:

  1. Drilling of Confirmation Well #1;
  2. Drilling of Confirmation Well #2;
  3. Testing and analysis of historical core samples, including the historical pilot (see below);
  4. Completion of additional seismic interpretation;
  5. Evaluation of resource potential and preparation of a NI 43-101 technical report; and
  6. Commissioning and completion of a preliminary economic assessment (“PEA”).

The Disley Project is located in southern Saskatchewan, approximately 50km northwest of Regina and covers approximately 9,413 hectares.

The property is situated immediately adjacent to the east of the K+S Bethune solution potash mine and north of the Mosaic Belle Plaine solution potash mine – two of the largest producing solution potash mines globally. In the opinion of management, the Disley Project is situated in one of the most favorable areas of Saskatchewan for solution mining as evidenced by the success of its neighbouring projects.

In the 1960s, a historical pilot project was conducted within what is now Buffalo’s Disley Project by the Lumsden Potash Development Company to evaluate the potential for solution mining using brine injection and recovery wells (the “Historical Pilot”). The Historical Pilot successfully demonstrated communication across the potash zone and the ability to extract potash using a two-well cavern system.

Buffalo has incorporated the results and geological data from the Historical Pilot together with 3D seismic interpretation and geochemical modelling to inform management’s preliminary geological interpretation and assessment of the broader Disley Project. Based on this information, management believes the Disley Project exhibits geological conditions present in other successful solution mining projects in the region, subject to further technical validation, making the Disley Project prospective for potential development of a modular, selective solution mining potash operation.
