Auckland, Nov 5, 2008 AEST (ABN Newswire) - Zedex Minerals Ltd (ASX:ZDX) is pleased to announce a further significant increase in JORC status gold resources at the Bau Gold Project in Sarawak, Malaysia. This increase (308,000 oz up from 05 August 2008 estimate) derives from ongoing geological assessment and resource modelling, which is progressively improving the definition of established gold deposits within central sectors of the Bau Goldfield.

As part of this ongoing programme, Ashby Consultants Ltd (ACL) of New Zealand has now completed a new independent review and update of the Jugan gold deposit and determined the grade and volume of historic mine tailings at the BYG Gold Mine site, near Bau township. This latest estimate increases the overall Bau resource to 1,612,000 oz of gold (refer to table 3 below).


The Jugan gold deposit comprises a compact body of sediment-hosted, carbonate-replacement style mineralization within Mining Lease 119 and Mining Certificate 1D/1/87, approximately 7 km northeast of Bau township. The mineralization extends over a strike length of 300 metres (NE-SW), with 75m width (NW-SE), extending at least 200 metres down dip (60 degrees NW).

The deposit is considered to be amenable to open pit mining.

Recent diamond drilling (310m in 5 twinned holes) has been conducted to improve the geological definition and validate historic assay results. In conjunction with results from an extensive check assay programme, these new drilling results were integrated into the Jugan database, which now comprises 14,663.65 metres of drilling (8,853.65m diamond and 5,810m RC) in 144 drill holes.

Incorporating these new drilling results and check assay programme results, new 10x10x5m block resource models were then run (using ordinary kriging) to compute the resource figures, as shown in Table 1 below:

Jugan Deposit @ 1g/t Au Cutoff
          (Mt)  (g/t Au)  GOLD (oz)
Indicated 9.226  1.66     492,000
Inferred  2.514  2.202    178,000
Total:   10.091  2.066    670,000
Relative to the prior resource estimate (10 June 2008), the above estimate represents a 28% increase in the Jugan JORC compliant gold resource. This study has also highlighted the potential for further increasing the resource and improving the resource classification through additional drilling.


At the historic Bukit Young Gold Mine site, auriferous tailings contained within a tailings dam in ML109 were recently auger drilled on a 25 x 25m grid pattern (505m) and sampled in one metre splits to check and extend the results of an historic survey (405m). These samples, which were assayed at an internationally accredited laboratory, revealed that the gold grade varies systematically throughout the tailings storage facility. The gold resource was then estimated (by ACL) using ordinary kriging of a 10m x 10m x 1m block model. The modelled resource is shown classified as indicated in Table 2 below:

BYG Mine Tailings
        (g.t AU) (Mt) (g/t Au) GOLD (oz)
Indicated 0.62  1.291  1.332   55,000
Inferred  0.62  1.878  1.332   80,000
Total:          3.169  1.332  135,000
The additional inferred resource shown in Table 2 is the difference between the modelled resource and the historic tonnage, as recorded in historic mine records. The 0.62 Au g/t cutoff off grade represents the minimum modelled block grade.


The latest Jugan revision and BYG mine tailings resource estimate lifts the current Bau JORC 2004 compliant global gold resource to 1,612,000 oz. Resource estimates (by sector) are now as shown in the following table:

SECTOR    Tonnes  Grade  Cutoff  Category Contained
          (Mt)  (g/t Au)(g/t Au)          Gold  (oz)
Sirenggok 7.185  1.23    0.75   Inferred  284,000
Pejiru    8.576  2.24    1.00   Inferred  497,000
Jugan     9.226  1.66    1.00   Indicated 492,000
Jugan     2.514  2.202   1.00   Inferred  178,000
BYG Mine 
Tailings  1.291  1.332   0.62   Indicated  55,000
BYG Mine 
Tailings  1.878  1.332   0.62   Inferred   80,000
Total: 1,612,000

The above results are part of an ongoing programme designed to progressively improve the definition and delineate the extent of known gold deposits within the Bau Goldfield. The 28% JORC resource improvement resulting from the twin drilling and check assay programmes at Jugan is encouraging, in that commensurate improvements may be surmised at Sirenggok deposit. Accordingly, check sampling of historic drill core from Sirenggok deposit is currently underway.

As previously announced (on 23 October 2008), a recent independent consultant report has identified a geological target of 4.6 - 5.8 M oz gold (which includes the above JORC resource of 1.612M oz gold) within a number of adjacent mineralization zones. Accordingly, a prime objective of the 2009 drilling programme will be to test these zones and convert this identified geological potential to JORC resource status. The 2009 drilling programme will also include provision for large diameter (PQ) diamond drilling, to extract representative mineralization samples for metallurgical test-work. Bulk sampling of the tailings resource is also planned, together with density determination, geodetic survey and gravimetric analysis and metallurgical analysis of the tailings.

During 2009, Zedex also aims to examine the feasibility of generating early cash flow from certain zones that are considered amenable to low-capex development.


The Bau Gold Project in Sarawak, East Malaysia comprises consolidated Mining and Exploration tenements that collectively cover 828 km2 of the most highly-prospective ground within the Bau Goldfield. Operating intermittently since 1864, the Bau goldfield has recorded 1.5 million oz gold production, estimated historic production of more than 3.0 million oz. Zedex holds majority interest and is operator of the Bau Gold Project Joint Venture.

Beyond the Bau Gold Project, the Joint Venture also holds a number of regional exploration tenements, covering 1,236.38 km2 of highly prospective, but relatively unexplored terrain in Sarawak. Exploration of these regional tenements is currently in progress.
