Geotechnical and Hydrological Drilling Program Begins at Colluli
The Colluli resource is a unique combination of potassium bearing salts suitable for the production of potassium fertilisers. It hosts 1 billion tonnes of potassium salts and has a current JORC Compliant Measured, Indicated and Inferred Resource.
SOUTH Boulder Mines (ASX:STB) (“South Boulder” or “Company”) is pleased to advise that mine and infrastructure geotechnical drilling, hydrological testing and dewatering drilling has commenced at the Colluli site in Eritrea, East Africa.
The drilling program will “twin” a number of the previously drilled resource holes as part of the transfer of the resource model from the Ercosplan to AMC Consultants.
Mobilisation and camp establishment was completed on time and the drilling program is being supervised by AMC Consultant representatives and South Boulder personnel.
The information collected will be used for both pre-feasibility and feasibility work. Drill results will be used to determine earthworks requirements for key pieces of infrastructure, dewatering infrastructure requirements, pit wall angles, trafficability of the upper layer materials for mine planning purposes, and material characteristics for solar pond construction.
South Boulder Managing Director, Paul Donaldson, said:
“We are pleased that we have been able to meet our target drill date given the relatively short period of time to source personnel, mobilise equipment, and obtain the required consumables for the program.
In addition to drilling activities, evaporation tests will be done on site to reconcile with weather data collected from site over the last two years and laboratory trials completed in Perth during the last quarter.”
