African Potash Limited ('African Potash' or the 'Company')
Update Re Drilling Campaign at Lac Dinga Potash Project

 

African Potash, the AIM listed exploration company focused on sub-Saharan potash assets, is pleased to announce an update regarding drilling activities at the Company's Lac Dinga Potash Project in the Republic of Congo ('Lac Dinga' or the 'Project').

 

Further to the announcement on 23 June 2014 regarding the appointment of RCT srl to undertake a maiden 1,000m diamond drill programme at Lac Dinga, the rig is now being mobilised and is anticipated to commence drilling at the first location within a few days.  This first phase drill programme, which will consist of two vertical rotary/diamond drill holes to a depth of ~500m, will test two high priority targets which demonstrate the potential for high-grade potash mineralisation based on the interpretation of seismic data.

 

Further Information on the Maiden Drilling Programme

 

The objective for the maiden drilling programme is to test the interpreted prospective salt sequence for the development of high-grade sylvinite (KCl) horizons within the basin-wide carnallite [KMgCl3 x 6(H2O)] layer.  The initial programme will include two approximately 400m to 500m deep vertical drill holes.  

 

It is expected that the holes will intersect the evaporite horizon between 300m and 350m below surface.  The drill holes are planned to be drilled as open rotary holes through the cover sequence consisting of mainly poorly consolidated sandstones, limestone and dolomites, and to be cased to the top of the salt and then PQ size (~9cm diameter) core drilling into the evaporite formation.

 

A geological study conducted by CSA Global Pty Ltd resulted in a regional structural geological framework and an interpretation of the extent of the evaporite (rock salt and potash salts) sequence across the Project area.  The study confirms stratigraphic-structural continuity of the salt (including potash horizons) into the Lac Dinga area.  The evaporite sequence is interpreted to underlie approximately 250km2 of the Project area and to thicken to about 300m to 400m near the southern and western property boundary.  The evaporite sequence appears to have relative consistent thickness up to the "salt basin" margin where it rapidly decreases in thickness over about 3km. The geometry of the evaporite sequence is controlled by a structure in the underlying rocks which defines the "salt basin" geometry.  Four drill target areas were identified near the basin margin where favourable conditions have been interpreted for the formation of high-grade potash mineralisation within the evaporite sequence.

 

The historic drill hole information confirms the development and presence of potash mineralisation in the form of sylvinite and carnallite in the area immediately to the south (~5km) of the Project area.  The records refer to layers of sylvinite and/or carnallite developed in the same stratigraphic position as that exploited in the nearby Holle historic potash mine.
