Zinc explorer finishes for '07

Base metals junior TNG Limited has finished drilling its Manbarrum project for 2007.

This year the zinc explorer completed more than 37,000m of drilling and consigned more than 20,000 samples for analysis.

The exploration cost $10 million and the company drilled a total of 149 holes. TNG is hoping to upgrade its resource estimate, with results due in January.

The project is thought to have 10.5 million tonnes of ore containing lead and silver. Manbarrum is 70km northeast of Kununurra.

Manbarrum 2007 Exploration Summary

4 December 2007

TNG Limited (ASX: TNG – “TNG”) advises that the major 2007 exploration program at its 100%-owned Manbarrum Zinc-Lead-Silver Project in the Northern Territory has been completed. All field based operations have ceased and will recommence in 2008 after the wet season.

During the year the following work was completed:

  • >23,000m of RC drilling
  • >14,000m of Diamond Drilling
  • >20,000 samples for analysis
  • 84 line kilometres of Induced Polarisation (IP)
  • 3,000 gravity stations surveyed


The $10 million exploration program for 2007, which was one of the largest undertaken in the Northern Territory this year, comprised multi-phase exploration activities and drilling across several deposits in the Manbarrum project area.

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


An extensive program of geophysics was completed, comprising 84 line kilometres of high powered Induced Polarisation (IP) surveys and 3,000 ground-based gravity stations. This has provided extensive and detailed data over the entire Manbarrum Project area which will assist in defining existing prospects and delineating new prospects. Detailed interpretation is underway.


In line with its strong commitment to the highest standards of environmental
management, TNG has completed the rehabilitation of all 213 drill holes and further fieldbased activities have now ceased for the duration of the northern wet season.

The Company has also completed environmental Baseline and Monitoring surveys.


Metallurgical test work has commenced on Sandy Creek drill core and preliminary metallurgical test work has commenced on Djibitgun drill core and RC samples.


Commenting on the announcement, TNG’s Managing Director, Mr Neil Biddle, said the 2007 field season represented one of the most significant exploration programmes in the Northern Territory and has confirmed the company’s view that the Bonaparte Basin represents a major MVT district of excellent economic potential.

“We are now in the process of compiling the significant amount of data and geological information collected, which will provide the basis for a much expanded field season in 2008 as we continue to advance towards our objective of developing a world-class base metal project at Manbarrum,” he added.

“We are also awaiting assays for Djibitgun samples, which are due during December”.

“We would like to take this opportunity to acknowledge the support of both the
Traditional Owners at Manbarrum and the NT Government departments, NTGS and DPIFM, in achieving the amount of work carried out during the limited dry season.

Resource estimates for Sandy Creek and Djibitgun are due for completion during January 2008.

Drill results promising

ZINC junior TNG Limited has received drill results of more than 2000 samples from its Manbarrum zinc lead and silver project.

The company said the results were encouraging and would go towards an updated resource estimate to be released after Christmas. Manbarrum is on
Lejune Station, 70km northeast of Kununurra on the NT side of the West Australian border.

TNG granted Northern Territorys 1000th Exploration License

TNG was today granted the Northern Territory’s 1000th Exploration Licence by the Minister for Mines, the Honorable Chris Natt, at an official ceremony at Parliament House in Darwin.

Mr Natt said this morning that reaching the 1000th Exploration License (EL) showed continued strong interest in the Northern Territory and proved that the government’s investment strategies were working well. He said that 333 ELs had been granted in 2000/2001 and that the number had increased to 757 for the year ending 2005/2006.

“This year there has been an average of more than 50 applications received each month and this is continuing,” Mr Natt said.

The 1000th licence was granted to a 100% owned subsidiary of TNG Limited (“TNG”). TNG is an Australian exploration company with a diversified portfolio of quality exploration projects in Western Australia and the Northern Territory and this, the 1000th Exploration Licence,  forms part of its Manbarrum project in the Bonaparte Basin near the WA border.

The 100% owned Manbarrum Zinc-Lead-Silver project, is TNG’s exploration priority with a significant proportion of the $10 million current year RC and Diamond drilling exploration program already completed.

Early results have confirmed Manbarrum as an extensively mineralized Mississippi Valley Type resource of potential global scale proportion.

TNG’s Chairman, John W Barr, described the marking of the 1000th license as an achievement both for the company and the Northern Territory Government.

“TNG is delighted to be the recipient of the 1000th Exploration License in the Northern Territory and looks forward to continuing its excellent working relationship with the Northern Territory Mines Department,” Mr Barr said.
