Titanium Sands Ltd (ASX: TSL) has announced highly encouraging results from the drilling efforts at its flagship Mannar Heavy Mineral Sands Project in Sri Lanka.
The resource infill and extension drilling has been continuing on TSL’s existing Mannar Island licenses.
The company reported that over 92% of the drill holes analysed returned intercepts of between 2% and 24% THM. Among them, 35% of intercepts were reported in areas outside the previously identified resource.
TSL said that the results confirm the continuity of the mineralised zones as well as potential for resource extensions in three separate zones.
The company expressed confidence that this drilling will contribute to a further resource update planned for September 2019.
Titanium Sands announced that further resource infill and extension drilling will continue at the Mannar island Project.
Titanium Sands Ltd holds five exploration licences a for heavy mineral sands located in North West Sri Lanka on Mannar Island and the adjacent mainland coast.
The Mannar Island is 26 kilometers long and 6 kilometers wide and 140 square kilometres in area. Hand auger drilling in 2010 and 2014 had demonstrated significant high grade concentrations of heavy minerals along the northern and southeaster portions of the Mannar coast.
The ilmenite-leucoxene project has an initial JORC inferred mineral resource of 10.3 Mt with total heavy mineral (THM) of 11.7%.
Drilling at Mannar
In April 2019, the company drilled 802 holes with sampling intervals of 0.5m on the Mannar Island Heavy Mineral Sands Project in Sri Lanka. This was designed to infill previous resource drilling from 400 metre spaced lines to 200 metre spaced lines.
The drilling, which targeted areas of potential resource extension, was also aimed at contributing to a further resource update.
The drilling was designed to address lateral and below the water table extensions to the existing resources; infill drilling on high-grade portions of the existing resources; and for testing new target areas on the tenure.
The company said that the drilling was undertaken by Sri Lankan geologists and a drilling team supervised and directed by James Searle, the Managing Director of The Company.
Results reported for 357 drill holes
Titanium Sands said that the results from 357 of the drill holes have been received to date.
TSL reported that the resource drilling further to the drilling used in the resource update succeeded in reducing the nominal resource drilling pattern down from 400m by 50m to 200m by 50m over 90% of the resource envelope.
High-grade intercepts from 92% drill holes
The company reported that of the 357 drill holes analysed, 330 holes returned intercepts between 2% and 24% THM (Total Heavy Mineral). This translates to over 92% of the analysed drill holes.
TSL said that of these, 126 were located outside the previously defined resource, indicating the potential for resource extensions in three separate zones.
The company said that all these mineralised intercepts are from surface and drilling was only down to the water table at 2m to 5m depth.
TSL said that the results from the remaining 445 drill holes are pending and will be reported in due course.
The company said that further drilling will test lateral and depth extensions of the areas of mineralisation defined to date.
Titanium Sands also said that the drilling will contribute to a further resource update planned for September 2019.
