Banio Potash Project


  • 100% Ownership Acquisition – Black Mountain Gold has entered into an agreement with Equatorial Potash to acquire up to 100% of the Banio Potash Project in Gabon through a series of cash and share payments and commitment of certain exploration expenditures
  • Large Potash – Bearing Basin with Drilling - Initial drilling intersects significant potash-rich horizons from 230m to 520m depths. Continuous carnallite and sylvinite seams ranging from 4.8m to 12.8m thick, significant potential for upside. Potential solution mining method and amenable to modular expansion decreasing initial CAPEX
  • Strategically Located with Good Infrastructure - Project located in the potash-bearing Congo Basin but situated in mining and development-friendly Gabon. Ideally located closer to Brazil than current suppliers supporting cost and time savings. Good infrastructure; Exploration Camp, drill rigs, drill core on site.
  • Solid Track Record of Management & Board - Experienced in potash and other large mining projects, with a track record of delivering enhanced shareholder value. Have developed and exited two large potash projects in Africa and North America.
  • Positive Dynamic in the Potash Sector - Significant supply constraints in Russia/Belarus. Solid potash price growth. Ideal time to invest in the potash sector as global supplies constrained due to the disruption and removal Russian and Belarus suppliers from the global markets


  • The Banio Project covers 1,244 km2 and is located in the south-west corner of Gabon approx. 450 km south of Libreville along the Atlantic coast. Banio is located on the seaward side of a long lagoon which extends from Mayumba in the north to the border of Republic of Congo.
  • Mayumba is a small port city approx. 50 km north of the main project area and is accessible by road and a major airport.
  • Access to Banio site via several accessible roads to Mayumba and waterways provide alternative access to the project.


The Banio project sits on the border with the Republic of Congo and is located 70 km north of the world class which hosts significant potash deposits and historical mines Kola and Dougou potash deposits. All of which are located within the same sedimentary horizons of the past-producing Congo Basin.  is in the northern extension of the, extensive ‘Congo Basin’ which hosts many significant potash deposits and historical 100 km to the south of Banio in the Republic of Congo.

The potassium bearing salt layers of the Republic of Congo extend into Gabon, at similar depths and thicknesses.

Nearby potash projects include:

  • Holle Mine extracted 7.4M tonnes@44% KCl
  • Mengo Project: 21.6Mt KCl@ 12-24% KCl
  • Kore Potash: Measured + Indicated Resources at
    • Kola:848Mt @ 34.8% KCl
    • DX Project: 152Mt@ 32.5% KCl
    • Dougou Carn: 3Bt @ 20.7% KCl


A three-hole drill program including BA-001, BA-002 and BA-003 was completed by Infinity Resources on the Alpha Section in order to test the previously reported Exploration Target.

Drill holes BA-002 and BA-003, drilled 2.2 km apart, were successful in intersecting multiple wide potash seams (see Figure 1 ). Drill hole BA-01 was stopped at 364 m after intersecting steeply dipping evaporites (ASX release 11 April 2017).

  • Initial Phase 2 exploration program to be expedited as drill equipment is on site and camp infrastructure in place for rapid start-up
  • Drilling to be followed by updated mineral resource estimate and continued permitting
  • Upon completion of the MRE, Phase 3 exploration will follow and include a resource update and a Preliminary Economic Assessment (PEA)
