Sudan Agrominerals Project

Key Facts:

  • Agromineral concessions prospective for potash, phosphate and gypsum
  • Concessions are under-explored in stable regions of northern Sudan, totalling 79,985km2
  • Phosphogenesis confirmed in Jebel Abyad; geological links with prolific North African phosphate mine trend
  • Potash salts confirmed in oil wells immediately south of the Red Sea Block; exploration in areas with geological correlations to potash deposits in Eritrea and Ethiopia
  • Outcropping gypsum in the Red Sea Block
  • Sudan
  • Farm in option to obtain 51% ownership of licence holder IMRAS available

Regency’s technical team is leading an exploration programme across several agromineral-prospective concession areas in stable regions in the north of Sudan.

Agromineral Uses and Outlook

Agrominerals form key components of fertilisers which help maximise crop production by contributing essential minerals and nutrients to soils. The Food and Agricultural Organization of the United Nations (“FAO”), estimates that world food production will need to rise by 70% to meet the demand of the global population growth forecasted by 2050. If the FAO’s predictions are correct, the importance of discovering new agromineral resources – phosphate, gypsum and potash in particular, will become critical. For food yields to increase at the rate projections could demand, essential crop nutrients must be provided.

Jebel Abyad Block - Phosphate

The Jebel Abyad Block (Phos7) is located in the north of the country and is prospective for sedimentary phosphate of Late Cretaceous age. Extensive reviews by the technical team at Regency Mines have indicated potential geological correlations between the Jebel Abyad sedimentary sequence and the economic phosphate deposits found in the prolific South Tethyan Phosphorite Province. This geological formation extends from the Middle East to the west coast of Africa and contains up to 79% of world phosphate reserves. Phosphogenesis, the process by which phosphate is concentrated into potentially economic concentrations, has been confirmed in Jebel Abyad and primary targets outlined in the Block after a preliminary field trip in November 2013. The next stage of exploration will be to confirm these targets on the ground and carry out a thorough mapping and sampling programme across the anomalous areas of interest.

Red Sea Block - Potash & Gypsum

Located 200km north of Port Sudan on the Red Sea coast, the Block forms part of the extensive Red Sea rift system, known to host economic evaporite potash formations such as the Colluli Deposit of Eritrea†. Historic oil well data from a borehole drilled 2km south of the Block indicates potassium-rich salt (“potash”) horizons at depth. Preliminary interpretation of this data indicates that the salt horizons are likely to project to surface within the Red Sea concession.  Trips to the area have also confirmed the presence of gypsum exposed at surface and work is currently underway to further delineate the extent and thickness of the formation. The next stage of fieldwork will be to confirm the existence, grade and mineralogy of any potash mineralisation at surface within the Block. 


The Changing Face of Sudan


Prior to the independence of South Sudan in 2011, Sudan’s exploration activities for natural resources focussed mainly on oil and gas. The Sudanese government is now actively promoting and encouraging investment from Western exploration companies in an attempt to diversify and expand the country’s industry. The resource potential of Sudan is not well known – less than 10% of the country has ever been explored for mineral deposits. Regency Mines is working closely with the Ministry of Minerals to maximise positive exploration outcomes, the results of which could benefit not only the Company but also the local economy and Sudan’s own agricultural development. It is an encouraging sign that Sudan has expanded its natural resource focus and is dedicated to assisting mineral exploration companies develop their projects in-country.

Exploration Partnership

International Mineral Resources (Agrominerals Sudan) (“IMRAS”), is a British and Sudanese-owned exploration company which holds a number of promising agromineral prospects in Sudan. Regency holds the right to farm in up to a 51% interest in IMRAS by exploration leading to the development of two JORC resources.
