Maputo — The British based mining company Savannah Resources has announced “positive” results from a ground magnetic test survey of the Jangamo heavy mineral sands deposit in the southern Mozambican province of Inhambane.
A release from Savannah describes the deposit as “world class”, and says it should be possible to detect the “geophysical signature” of the deposit using an airborne platform. This would allow Savannah “to rapidly advance exploration at a lower cost”.
Hence a helicopter-borne magnetic and radiometric survey is planned in early May across the 180 square kilometre area licensed to Savannah. This, the release says, “will define the extent of the heavy mineral sands system and any re-worked strand lines, which are likely to carry higher grades”.
Cited in the release, the Savannah chief executive David Archer explained: "The success of the ground magnetic test programme over the anomalous drill holes returned from the scout drilling programme is very important to the overall speed and cost of the exploration programme for the Jangamo project”.
“The heliborne magnetic survey will help us define the overall mineralised system and more importantly any potential re-worked strand lines, which will carry higher grade heavy mineral sands”, he added. “The project is now poised for further positive results as our 2014 exploration programme is rolled out.”
Heavy mineral sands contain such ores as ilmenite (titanium iron oxide), rutile (titanium dioxide), and zircon (zirconium silicate).
The license for the Jangamo deposit was originally held by the Mozambican company Matilda Minerals. Savannah acquired an 80 per cent interest in Matilda Minerals in October 2013.
