Tchitondi Permit

The Tchitondi permit area is located in the eastern portion of the Republic of Congo (ROC) onshore basin up to the basin edge. The permit is 83,600 acres and contains the last nine (9) evaporitic cycles, as the Loeme salt erodes and pinches out close to basin edge. Holle Potash Corp. (HPC) expects the Loeme salt to be encountered at depths of less than 600 m up to surface, in a geological setting similar to that of the former Holle mine. The Tchitondi license includes a portion of the licence that was covering the Holle mine. Tectonics, weathering and NaCl saturated brine solution means that much of the carnallite deposited in the area may have been altered into sylvite, thus producing sylvinite which was the main mineral mined at the Holle mine. HPC expects to prove some carnallite resources in the Western outboard of the permit.

Data from the former Holle Mine and new seismic acquisition as well as drilling and surface geology will help define the potash resources in the Tchitondi area. Based on previous work completed by Feuga et Al in 2005 which estimated potash (K2O) resources of carnallite and sylvite at 30 billion tons for the 1,300 km2 around the Holle mine, HPC expects gross K2O resources of 6 billion tons in its 334 km2 Tchitondi permit area, with potential mineable resources in excess of 1 billion tons of K2O. These numbers need to be further confirmed by a NI-43-101 report which the company will initiate.

Mining methods in the Tchitondi area vary from Surface strip mining to underground mining and solution mining. The area is tectonically complex and it is this complexity that led to the flooding of the Holle mine after miners accidentally breached an aquifer. A feasibility study will define the best, most profitable, cost effective and sustainable mining method.
