Geotechnical Site Investigations for Feasibility studies. Sahara carried out review of historical log data, detailed geotechnical and structural core logging for optimum pit design. Sahara also supervised rotary core drilling, in situ testing, sample prep and analysis for TSF design.
PROJECTS BY SAHARA NATURAL RESOURCES
Name: Geotechnical Studies for Mine Feasibility Studies
Country: Cote d’ivoire
Commodity: Au
Name: Resource and Reserve Estimation
Country: Togo
Commodity: P
We were commissioned to undertake a Resource and Reserve Estimation of a phosphate mine near Lome to the south of the Republic of Togo. The scope of the work included, Geology, Resources, Geotechnical and Hydrogeology, Mining Engineering, Fleet and Maintenance Review, Metallurgy & Plant Design, Capital Expenditure and Plant/Equipment Budget and Plan, Operating/Processing Plan, Infrastructure, Permitting/Approvals and Financial Model.
Name: Auger Drilling Campaign
Country: Burkina Faso
Commodity: Au
Sahara assisted clients in South West Burkina Faso with a significant auger drilling program covering several permits and in different, sometimes challenging, terrains. Samples were taken from a 20m depth and were handed over to clients for testing. Drilling was supervised at all times by one of Sahara’s senior geologists.
The drilling program contributed to the discovery of a multi-million-ounce gold deposit.
Name: Railway Geotechnical Site Investigation
Country: Ghana
Commodity: N/A
Sahara Geotech team carrying out Geotechnical Site Investigation for the railway section between Tarkwa and Huni Valley along the existing railway line using one of Sahara’s Cortech rigs.
The site activities included HQ3 drilling with in-situ testing (Standard Penetration Testing) at pre-determined intervals. There were also some selected boreholes which had standpipe piezometers installed in them to monitor the ground water levels.
Name: Mining Operations
Country: Togo
Commodity: Mn
Sahara supervised and managed the mining process for the 200,000 tons of Manganese ore from the initial test mining carried out for testing the quality of the ore.
The project located in Togo is soon to start operations.
Name: Wingtra (UAV Survey)
Country: Nigeria
Commodity: Ni
Sahara was contracted to perform a UAV topographic survey at the client’s project in Nigeria.
The objective was to accurately measure and produce a topographic data to 10cm accuracy.
Deliverables included 1m contours surveyed data to 10cm accuracy in DXF format and georeferenced orthomosaic image of survey area at 10cm resolution.
Name: Manportable drilling around cashew fields
Country: Cote d’Ivoire
Commodity: Au
Team Sahara made is way around cashew fields with manportable rigs in East Ivory Coast to take samples at required depth while ensuring not to damage crops of local farmers.
We take our client’s public relations seriously and ensure that exploration programs are conducted with genuine consideration for the environment and local communities.
Name: Mine Geotechnical studies
Country: Burkina Faso
Commodity: Au
Drilling, Material (field & lab) testing and analysis of field data for TSF design. Also the drilling and installation of monitoring instruments.
The picture was taken as a massive dust storm from the Sahara Desert approached our Geotechnical Drill Rig.
Name: Underground Surveying
Country: Mali
Commodity: Au
Sahara with our Australian partners, Land Surveys were contracted to provide survey services for a client’s Underground Mine Automation Project in Mali.
The services included survey pickups for design, all infrastructural setting out, monitoring and supervision of construction works to standards and the final as-built survey of all infrastructure.
The mine has since become the World’s first fully automated underground mine.
Name: ERP System Implementation
Country: Multi-country
Commodity: N/A
Sahara implemented a state-of-the-art cloud-based Enterprise Resource Planner (ERP) for optimal management and reporting in the mining and professional services industry across several countries and continents.
The implemented platform enabled the management of multi-country, multi-language, multi-accounting standards and multi-currencies operations.
The system features included real time financial consolidation, system alerts, automatic email reports, remote warehouse management, timesheets, purchasing, CRM, fixed assets, etc.
Name: Aircore drilling campaign
Country: Cote d’ivoire
Commodity: Au
This relatively inexpensive and often-used first pass exploration drill program was conducted in North Ivory Coast. The carefully collected samples were handed over to the client for analysis and encouraging results lead to more investigation and drilling in the area.
Name: Field Investigation
Country: Togo
Commodity: Ni, Co
Sahara was contacted to work on permits located around the Kotora and Ayagba environs in Togo. Substantial amounts of Nickel and Cobalt were discovered after XRF analysis indicated high concentrations of the said commodities in most of the sampled regions.
