Sydney, Nov 25, 2008 AEST (ABN Newswire) - Citadel Resource Group Limited (ASX:CGG) is pleased to announce that it has received further gold results from the second drilling program at its 100%-owned Jabal Shayban Gold Project in Saudi Arabia. Gold assay results have been received for a further 7 reverse circulation ("RC") drill holes of the continuing 40 hole drilling program.
Highlights:
- RC drilling continues to outline significant gold-rich zones at Jabal Shayban.
- Good continuity of primary and oxide high-grade gold zones demonstrated.
- Results include:
SH048RC - 31m at 6.89 g/t gold from 15m including 16m at 10.13 g/t.
SH051RC - 42m at 4.59 g/t gold from 0m including 9m at 12.67 g/t.
SH044RC - 76m at 2.19 g/t gold from 18m including 7m at 10.05 g/t.
- A diamond drilling rig has been mobilized to site and has commenced testing deeper targets within the Shayban Deposit.
All holes intersected significant gold mineralization from surface, or near surface. Results included 31m at 6.9 g/t Au from 15m including 16m at 10.1 g/t Au (SH048RC), 42m at 4.6 g/t Au from surface including 9m at 12.7 g/t Au (SH051RC), 76m at 2.2 g/t Au from 18m including 7m at 10.0 g/t Au (SH044RC), 36m at 1.7 g/t Au from 14m (SH045C) and 39m at 1.4 g/t Au from surface (SH050RC). Silver and base metal results are pending and should be available in a further 3-4 weeks. A complete listing of the results is given in Table 1.
Citadels drilling programs over the past year have discovered multiple "stacked" gold zones within the Shayban deposit. Several high-grade zones have been delineated adding significantly to the project. Drillhole SH031RC (39m at 37.8 g/t gold - previously announced) intersected one such attenuated high-grade shoot. Together with intersections from SH048RC (31m at 6.89 g/t gold - this announcement), SH043RC (50m at 4.70 g/t gold - previously announced), SH044RC (76m at 2.19 g/t gold - this announcement) and SH051RC (42m at 4.59 g/t gold - this announcement) these intersections define a shallowly south plunging (20 degrees) continuous body that has a strike extent of 150mCitadel continues to extend and define this and other similar shoots within the Shayban deposit.
Citadel's ongoing exploration drilling program continues to demonstrate Jabal Shayban's potential to host a significant mineral resource. Mineralisation has now been delineated over a strike length of 550m and is currently open along strike (to the north), down dip (to the west) and down plunge (to the south). With the recent mobilization to Shayban of a diamond drill rig Citadel will be in a position to test the depth extensions of the Shayban system in the coming month.
The Shayban Project
The Jabal Shayban deposit is hosted within a sequence of highly prospective, weakly metamorphosed, felsic to intermediate volcanoclastics that includes subordinate units of chert and marble. This sequence is, in turn, intruded by a suite of dioritic and syenitic intrusions. Exploited by ancient miners the Shayban prospect area is marked by an extensive zone of alteration and gossanous outcrops.
The mineralisation at Shayban forms south plunging, westerly dipping, semi-continuous lodes that are currently open down plunge, down dip and along strike. Within the prospect area mineralisation mainly occurs within the "Shayban Shear Zone" a locally significant deformational zone that is mapped for in excess of 2.5km in the immediate area.
As illustrated by Figure 1 (965mE Long Section) the lodes are boudinaged out along the Shayban Shear Zone. In long section the lodes have an attenuated, "pinch and swell" morphology that are traceable for in excess of 600m along plunge (currently open). Within these attenuated horizons several high-grade gold, sulphide-rich "shoots" have been intersected. These variably boudinaged shoots can have strike extents of up to 150m, a dip extent of about 70m and a maximum true thickness of 30m.
There are two main mineral phases identified at Shayban, the first and most important, is a gold-rich volcanic-hosted massive sulphide (VHMS) event marked by the presence of conformable massive to semi-massive sulphides and associated stringer and disseminated sulphides. This style of mineralisation accounts for much of the contained gold at Shayban. The secondary mineral phase is a late-stage, high-grade, quartz-telluride gold bearing vein system that propagates throughout the "Shayban Shear Zone".
Wadi Shugea Regional Exploration Potential
Jabal Shayban is contained within Citadel's Wadi Shugea project which covers 203 sq km's of the highly prospective Neo-Proterozoic Ariab-Samran-Shayban volcanic belt. The Ariab-Samran-Shayban volcanic belt extends for in excess of 1000km from the Nile Valley in Sudan, north-eastwards across the Red Sea into Saudi Arabia. The belt hosts several significant gold and base metal mines, from Sudan (Hassai gold-rich VHMS deposit (+2Moz)) in the south through to the Mahd Adh Dhahab (Cradle of Gold deposit +5Moz) and Citadel's Jabal Sayid deposits to the north. The VHMS and precious-metal epithermal deposits of the Ariab-Samran-Shayban mineral belt form a world-class mineral province that Citadel believes will deliver further discoveries in the near future.
In addition to containing Citadel's advanced Jabal Shayban and Jabal Baydan deposits the Wadi Shugea project hosts numerous other, less explored prospects and occurrences that include gossans, ancient workings, anomalous geochemistry and geophysical anomalies. Citadel considers the potential for the discovery of both base-metal and gold-rich VHMS and epithermal precious-metal deposits within the Wadi Shugea project to be high and has planned an aggressive exploration program for the year ahead.
