Toliara Sands Exploration

World Titanium Resources has four exploration targets which comprise the Toliara Sands Exploration Project. These include Ranobe, Ankililoaka, Basibasy and Morombe.

 

Morombe

Exploration work to date indicates that the “Big Dune” area at Morombe contains higher TiO2 ilmenite as well higher zircon grades than Ranobe. The area has abundant water which would allow a dredging operation. The ultimate potential seen is for a large-scale operation which could support the infrastructure capital required to export a product through a port created at Morombe.

A drilling program is planned for 2012 with several lines across the area following up earlier reconnaissance hand auger sampling results. The aim is to clarify the stratigraphy of the area, collect samples of heavy minerals (HM) for further analysis and determine the potential for economic mineralization.

 

Ankililoaka

At Ankililoaka, 25km north of Ranobe, drilling encountered intersections over a distance of 5000m, in young quartz sands and clay sands, to both the north and south of a northwest trending ridge of limestone. Based on the drilling, the exploration target at Ankililoaka is 360-368 million tonnes containing 5 – 6% THM and 8.5 – 9.5% Slimes.  The heavy mineral suite is similar to Ranboe and is dominated by ilmenite (52%), leucoxene (5%), rutile (1%) and zircon (4%) with the TiO2 content of the ilmenite ranging from 47.6 to 56.8% TiO2.

 

Basibasy

At Basibasy, 60km north of Ranobe, there appears to be a shoreline running roughly through north- south, with clay-rich  sediments to the east. West of this “shoreline” the sediments are more sandy and drilling encountered significant  mineralisation (ie 39m at 7.0% HM) in quartz sands in an area around 2km by 3km. The Exploration Target based on this drilling is around 440-446 million tonnes containing about 4.5%- 5.5 THM and 8 – 9% Slimes. The heavy mineral suite is dominated by ilmenite (50%), leucoxene (16%), rutile (1%) and zircon (7%) with the TiO2 content of the ilmenite ranging from 50.2 to 59.6% TiO2 and therefore appears to be different to that at Ranobe.
