Austra l ian gold and nickel focused explorer, St George Mining Limite d ( ASX: SGQ ) ( ‘St George Mining’ or ‘the Company’ ) is pleased to pro v ide an update of exploration activities at t h e Blue Thunder Gold P roject located at its Pine Creek Property in the Northern Territory.
In advance of a diamond drilling p r ogramme at the Pine Creek Property scheduled for October 2011, St George Mining has been c onducting a comprehensive review, utilising industry leading technology to re-scan the historical d rill cores.
The previous explorer at the Pine C r eek Property, Homestake Gold of Australia L imited (“HGAL”), carried out a successful regional diamond drilling programme over a broad ar e a of the Fenton shear zone that included EL 27732, a tenement that now forms part of St Geo r ge Mining’s Pine Creek Property. HGAL was part of the Homestake Group, one of the largest global gold miners during the 1990’s, and now merged w ith Barrick Gold Corporation.
Carbon and sulphide-rich gold min e ralisation was intersected by HGAL at the c u rrent Pine Creek Property within the extensive and highly mineralised Koolpin Formation, which also hosts the Cosmo Howley gold mine about 30 km to the northeast. The most signif i cant broad drill intersections from the historical drill cores are listed in the tables below:

VISIBLE GOLD
As part of its review of the historical d rill cores, the Company has identified visible gold within FEND 18. Figure 1 (below) shows the visible gold i n FEND18, at 424m down-hole depth, with a larg e grain circled.

Figure 1 – Visible Gold in FEND18
The existence of visible gold in this en v ironment is very encouraging as it indicates the mineralsing fluids contained elevated levels of gold, in ex c ess of what could be absorbed by the carbon and sulphide rich host rocks, which form as free gold.
FEND 18 was the discovery drill-hole w ith significant high-grade intersections (see tabl e -1). It was drilled 1,200 m SSE of FEND 14 and intersect e d the higher grade gold zone approximately 200 m higher than the intersection in FEND 14. This confirms t he presence of a large gold system at the Comp a ny’s Blue Thunder Gold Project and the potential for verti c al and lateral extensions to the known gold mine r alisation.

The HGAL drilling was based on magn e tic modeling of the interpreted pyrrhotite-rich m ineralisation and the current depths of the intersection s reflect this. The magnetic modeling would not h ave identified updip zones of oxidized gold mineralisati o n, where magnetic pyrrhotite appears to be alt e red non-magnetic pyrite. This suggests potential for up-dip extensions to the known mineralised zone.
The Cosmo Howley gold deposit, wher e 2+ MozAu has been recovered by open and und e rground mining, is also hosted by the Koolpin Formation and situated on the sheared eastern limb of a regi o nal anticline (Pine Creek Shear). The Company’s Blue Th u nder Gold Project is also hosted by the folded continuation of the Koolpin Formation.
Figure 2 (below) illustrates the proxim i ty of the Blue Thunder Gold Project relative to t he Cosmo Howley deposit. The close similarities between the geological structures at the Cosmo Howley d e posit and the Blue Thunder Gold Project provide addition a l support for the potential of up-dip mineralisati o n from the known gold intersections in FEND14 and FEND 1 8.

CSIRO HyLogger
Both of the historical drill cores are being analysed using the CSIRO HyLogger hy p erspectral logging technology. The CSIRO HyLogger employs reflectance spectroscopy to determine the d iagnostic spectral features indicative of the mineralogy, m ineral chemistry and physical characteristics of d rill cores. Many of these factors are undetectable to the n a ked eye. A report on the results of this analysis is expected shortly.

The information produced by the H y Logger will assist in evaluating the nature of the previous drill intersections: specifically, the relative position of FEND14 and FEND18 within the larger gold system, and the potential for rare earths and urani u m in that part of the Pine Creek Property. This in f ormation will also assist in future drill hole placement.
2011 Drilling Programme at Pine Creek
An orientated diamond drilling progr a mme is planned for the Pine Creek Property in October 2011. Previous core drilling by HGAL was no t orientated; as such, the structural orientation of the higher grade gold mineralisation can only be inferr e d from the previous drilling. A Mine Managem e nt Plan has been submitted to the Department of Resou r ces and finalisation of the Plan is expected withi n approximately 30 days.
The purpose of the diamond drilling pr o gramme will be to:
-
Confirm the high grade interse c tions in FEND18
-
Identify the up-dip potential of mineralisation and the “top” of the system
-
Test the down dip extensions o f the ore shoot in this area
Further details of the 2011 drilling prog r amme will be announced after approval of the Mine Management Plan is obtained.
