Manbarrum Project Location Map

 

Key access clearance was granted in 2006 from the Aboriginal Areas Protection Authority (AAPA) for the Manbarrum project and field exploration commenced.

TNG completed an intensive RC and Diamond drilling program resulting in the discovery of several deposits in the Manbarrum project area in 2007.

A total of 20,614 samples were collected for analysis consisting of 15, 722 RC drill samples and 4,892 diamond drill samples from the Sandy Creek Resource, and Djibitgun prospects.

In March 2008 TNG unveiled a major increase in the JORC Mineral Resource inventory for the Manbarrum project to a combined polymetallic resource base of 35.9 million tonnes of lead, zinc and silver resources.

A total of 52 RC holes and 5 diamond drill holes were completed to undertake an initial evaluation of the Djibitgun area, with a maiden resource estimate of 19.9 million tonnes at 16.4/t Ag recorded for the Djibitgun deposit.

A limited diamond drilling programme was also successfully completed at the Browns Prospects in July-August 2009, where additional Zn/Pb mineralisation was intersected.

The Browns Prospect is defined by a chargeability anomaly of similar (if not greater) amplitude to the chargeability anomaly associated with the Sandy Creek deposit.

The initial resource estimate on the Sandy Creek Deposit was carried out in April 2008 and was recorded as 15.97mt @ 2.3% Zn+Pb, 5.4g/t Ag (JORC Indicated/Inferred) reported at a cut–off grade of 1% zinc.

A new resource estimate was completed on the Sandy Creek deposit by Snowden Mining Industry Consultants in 2010 and integrates TNG’s increased understanding of the Sandy Creek geology and controls on the mineralisation.

The updated mineral resource estimate has resulted in an increase of 54% to 24.4mt @ 2.26% Zn + Pb, at a cut-off grade of 1% zinc. At a 1.5 % Zn cut-off the resource stands at 12.6mt @ 2.96% Zn+Pb.

The exploration has confirmed the project's status as an Mississippi Valley Type (MVT) district of excellent economic potential.

In May 2010 Teng Fei Mining Ltd (TFM) made an offer to purchase the Manbarrum project from TNG which was accepted.

TNG will maintain an interest in the project, assisting with the project development, and will retain a 2% Net Smelter Return.
