ADV - Jabal Sayid, substantial drill intersections of high grade mineralisation
ADV Group Limited (ASX : ADS) is pleased to release assay results from diamond core drillholes BDH-1015 and BDH-1016 completed at Zone 1 of the Jabal Sayid Copper Project, near Jeddah in the Kingdom of Saudi Arabia.
• BDH-1016 intersected 96.85 m at 0.71g/t Au, 41.6g/t Ag, 3.28% Cu and 1.55% Zn (4.94% Cu Equiv.) from 153 m to 249.85 m downhole including 68 m at 0.82g/t Au, 47.5g/t Ag, 4.42% Cu and 1.53% Zn (6.15% Cu Equiv.). This drillhole ended in mineralisation.
• BDH 1015 intersected 84m at 0.45g/t Au, 27.0g/t Ag, 1.80% Cu and 1.43% Zn (3.17% Cu Equiv.) from 142 m to 226 m downhole including 11 m at 0.72g/t Au, 40.5g/t Ag, 3.97% Cu and 1.20% Zn (5.38% Cu Equiv)
Drillholes BDH-1015 and BDH-1016 were sited on the southern end of Zone 1 approximately 100m from the previously announced drillholes BDH-1013 and 1014. Drillholes 1013-1016 were drilled about 50 metres apart and targeted to be drilled through the interpreted Zone 1 lode at regular intervals along the strike of the lode. Details of the intercepts are shown in the table below. The attached plan and section across Zone 1 show the distribution of mineralisation from current and historical drilling and highlight the potential at depth.
Commenting on these drill results ADV Group Chairman, Mr Fletcher Quinn, said:-
“Hole BDH-1016 intersected an extremely high grade core of mineralisation, grading 0.82g/t Au, 47.5g/t Ag, 4.42% Cu and 1.53% Zn over 68 metres. This is US$350 tonne ore and is equivalent to 6.15% Cu, 17 g/t gold, or 9.3% Zinc, and demonstrates the potential for large widths of high grades at Jabal Sayid.
This hole also intersected a combined 145m of mineralisation in three zones in what is clearly a large mineralised system. It is noteworthy that this system outcrops at surface, enhancing the economics of the project and our open cut model. The current RC program will more clearly define the surface potential.
These holes confirm that zinc, gold, and silver credits, add significantly to the overall grade of the deposit with zinc, silver and gold in these holes accounting for around half of the mineralisation by value.
As the cross section illustrates, Zone 1 remains open at depth and shows no signs of the grades, or widths, diminishing at depth.
These results again reinforce our view that Jabal Sayid is likely to rapidly emerge as a world class orebody and that the grade in the previously announced open pittable target of 100-150mt at 1-1.5% copper, based on the 50 kms of previous drilling, may prove to be conservative ”

The intercepts in metal equivalent (estimated as Cu Equiv. %) have been calculated based upon spot metal prices of 21st January 2007. Four or five holes are planned for Zone 4 commencing in late January 2007 when the second drill rig arrives on site. As well a number of RC drillholes are currently being undertaken in the oxide zones of Zones 1 and 2 where core recovery has been poor. Vertex will be re-assaying selected sections of past drillholes commencing in January 2007. Results of this work will be reported when they become available.
Note 1: All the BRGM Cu analyses were undertaken by acid digest AAS techniques common to that time with rigorous standards and duplicate check procedures. All the BRGM drillholes were downhole surveyed using downhole camera technology. All the Vertex analytical work has been undertaken by Al Amri laboratories using similar techniques for base metals and fire assay (50g) for Au. Vertex sampled half HQ core (cut with a diamond core saw) at 1m intervals.
Note 2: The information in this report that relates to Exploration Results, Mineral Resources or Ore Reserves is based on information compiled by Ralph Stagg, who is a Member of the Institution of Materials, Mining and Metallurgy, a Chartered Engineer and a Fellow of the Australasian Institute of Mining and Metallurgy, a Chartered Professional, and is the technical director of Bariq Mining. Ralph has sufficient experience relevant to the style of mineralisation and type of deposit under consideration and to the activity he is undertaking to qualify as a Competent Person as defined in the 2004 Edition of the "Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves". Ralph consents to the inclusion in the report of the matters based on his information in the form and context in which it appears.
BACKGROUND ON VERTEX
ADV has previously announced that it is acquiring 100% of Vertex. Vertex has an exciting portfolio of Copper, Gold, and other Base and precious metal projects on the Arabian Shield in Saudi Arabia. The projects are held by Vertex’s 70% owned Saudi Arabian operating subsidiary Bariq Mining Ltd (“Bariq”). Bariq is currently earning a 50% interest in the Jabal Sayid project and holds a 100% interest in other projects including:
Jabal Shayban: gold/copper project is located on the Shayban Mineral belt, the south-eastern extension of the Mahd Adh Dhahab/Jabal Sayid mineral belt. A JORC compliant Measured and Indicated resource of 1.8Mt at 2.7 g/t Au, 23.1 g/t Ag and 0.47% Cu (253,000 oz Au Equiv.) was reported by the previous operator in 1999.
Jabal Baydan: zinc/gold project is located 10km from Jabal Shayban. An exploration target size for the mineralisation of 0.5-0.7 Mt at 15-18% Zn (100,000 t Zn) and 1-3 g/t Au (~40,000 oz Au) was estimated by a previous operator based on 24 drillholes.
Lahuf: is located 6 km from Mahd Adh Dhahab gold mine, a World-class epithermal gold project where historically more than 6 M oz of gold production has taken place. Lahuf has a JORC compliant Measured and Indicated resource of 1.2 Mt at 2.83 g/t Au (113,000 oz Au) and an Inferred resource of 0.4 Mt at 2.0 g/t Au (23,000 oz) in shallow, mainly oxide breccia veins reported by the previous operator in 1999.
Bari: project consists of lightly explored ancient gold workings covering a strike extent of some 1.4 km. Previous drill results included 39m at 7.32 g/t Au, 12.86 g/t Ag and 1.2% Zn and 84m at 6.75 g/t Au and 5.1 g/t Ag.
Wadi Kamal: project is a virtually unexplored layered ultramafic complex where the only recorded drill hole intersected 17m 0.53% Ni and 0.23% Cu with PGE’s up to 1.2 g/t.
Muraijib-Bil’iwy: project where limited (3) trenching of a major alteration system which cover areas varying from 150 m2 to 1,000 m2 intersected 32m at 1.75 g/t Au and 12m at 1.8 g/t Au.
