African Potash, the AIM listed company focused on sub-Saharan potash assets, has completed and intersected multiple potash seams at its second exploration drill hole at its Lac Dinga Potash Project in the Republic of Congo. This drill hole was defined on the interpretation of approximately 415 line kilometres of 2D oil industry seismic data, which successfully intersected potash mineralisation. It drill hole is situated at one of two target locations.
The objective for the maiden drilling programme was to test the interpreted locations for the presence of the prospective salt sequence and for the development of high-grade sylvite (KCl) within the carnallite bearing layers.

Exploration drill hole 2 was drilled in the central part of the project area where a potash-bearing salt sequence was located below a uniformly developed anhydrite layer at the top of the salt. The seismic data indicated a laterally flat to moderately undulating and undisturbed salt horizon throughout the target area.
The drill hole intersected the salt sequence at about 346 metres below surface and the base of the salt is at 458 metres below surface. The salt sequence measures about 112 metres, is composed of three salt cycles separated by two 5 metre to 10 metre-thick layers of claystone.
The salt sequences contain a cumulative thickness of 48 metres of potash beds – about 43% of the total interval. The salt sequence and potash mineralisation provides a positive indication of the lateral extent, and therefore potential for potash mineralisation with the Company’s Lac Dinga permit.

“The successful intersection of multiple potash seams at Lac Dinga from our first two hole exploration drill programme is an exceptional endorsement for our exploration concept,” says African Potash CEO, Edward Marlow. “It supports our confidence that the project has the potential to host a large-scale commercial potash mine. This is an initial indicator for the wider resource potential of Lac Dinga, and we can now move forward with confidence and plan further exploration activities in order to continue to prove-up the tangible value of the project.”
