[Ferro-Alloys.com]TopTung Ltd (ASX:TTW) has got confirmation from two independent laboratories that its tungsten concentrate from the Torrington Project located in northeast New South Wales is a marketable product.

Generally, the market will accept a 62% tungsten trioxide concentrate although 65% is preferred – TopTung’s concentrate has assayed 69%.

Furthermore, the high quality concentrate was produced using a simple non-chemical separating processing method and contained no deleterious elements.

The remaining 700 kilograms of the original bulk sample for metallurgical test work will now be processed by mid-October and further test work will be carried out on diamond core in 2017.

The company is in the process of advancing permitting in order to conduct a drilling programme at Torrington.

Torrington has been historically mined for tungsten, bismuth and topaz.

Tungsten is considered a critical raw material of economic importance giving rise to the strategic significance of the Torrington project.

At the end of the June quarter, TopTung had $4.6 million cash.
