Great Western Minerals Group Reports on New Phase of Steenkampskraal Rare Earth Drill Program (ccnm)
SASKATOON, SASKATCHEWAN--(Marketwire - July 3, 2012) - Great Western Minerals Group Ltd. ("GWMG" or the "Company") (TSX VENTURE:GWG)(OTCQX:GWMGF) today reported on the latest phase of its drill program at the Steenkampskraal rare earth property in South Africa. The following drill intercepts from four areas surrounding the main mine workings, are all outside the previously reported National Instrument 43-101 Resource Calculation (see:GWMG May 31, 2012 news release). A map of the Steenkampskraal drill program is at http://www.gwmg.ca/gwmg-nr-3-jul-12.html
.
The historic mine "vein" is comprised predominantly of a rare earth-bearing monazite. The vein is variably south-dipping, pinches and swells from < 1 cm to > 5 metres, and was developed over a strike length of approximately 400 metres. "Mineralized" intersections of vein material are composed predominantly of a cerium and lanthanum enriched monazite, and contain concentrations of all of the rare-earth elements and yttrium in consistent proportions. Past production, and extensive assaying from the first phase of drilling and underground sampling, indicates that monazite vein material at Steenkampskraal contains from 0.4 to 46% TREO with a modeled average of 18%. Grades typically are dependent on the amount of diluting materials within the vein structure such as quartz, feldspar, and sulphides.
Highlights of the Western Extension drill program include: •REE-bearing monazite vein mineralization encountered in seven of eight drill holes, and •Mineralization up to 3.73 metres true thickness.
Highlights of the South Eastern Extension drill program include: •REE mineralization encountered in ten of twelve drill holes, and •Mineralization up to 3.0 metres true thickness.
Highlights of the Eastern Flats Extension drill program include: •REE mineralization encountered in ten of seventeen drill holes, •Mineralization in excess of 3.0 metres true thickness in 3drill holes, including up to 5.11 metres true thickness.
Highlights of the Office Block Extension drill program include: •REE mineralization encountered in seventeen of twenty drill holes, and •Mineralization up to 2.24 metres true thickness.

* Drillholes STKEXP-001 and STKEXP-002 located in the Western Extension closest to the historic underground workings were included in the recent National Instrument 43-101 Resource Calculation. Notably, the thickest intercept of 3.73 metres was from STKEXP-002. Detailed drill program data is at http://www.gwmg.ca/gwmg-nr-3-jul-12.html

GWMG President and Chief Executive Officer Jim Engdahl said, "We are very pleased with the success to date with the new phase of our Steenkampskraal drill program. While massive to disseminated REE-bearing monazite does not automatically translate into uniform high grades, we are very encouraged by the significant extensions of mineralization adjacent to the previously announced mineral resource (see GWMG news release May 31, 2012) that have doubled the area of interest to over 800 metres along strike. These results give the Company a high degree of confidence about expanded development of this rare earth project."
South Eastern Extension:
Mineralization extends southeast for approximately 100 metres from the recently modeled resource area of historic mine underground workings. More infill drilling is required in order to test vein character proximal to the very thick monazite vein encountered in resource evaluation drillhole STK116 and to equally thick vein intersections encountered towards the bounding Eastern Flats Extension.
Western Extension:
As understood to date, monazite mineralization in the Western Extension appears to form a westward oriented wedge at depths of less than 80 metres. The mineralization varies up to 3.73 metres true width, similar to the western side of the known mine mineralization, but is characterized by significant entrained felsics and quartz. While mineralization does appear to pinch out towards surface approximately 100 metres westward from contiguous known mineralization, indications of a southwest down-dip plunge have not yet been tested.
Eastern Flats Extension:
The Eastern Flats Extension covers a broad area approximately 125 metres southeast and east of the known mine mineralization. The significant number of drill holes without intersections of mineralization reflects delineation of an area defined by minimally mineralized structure equivalent to the thinning monazite vein extending east and southeast from the immediate mine area. Beyond this pinched-out area, a significant new zone of mineralization has been partially defined. Three, dipping, north-oriented holes intersected mineralization in excess of 3.0 metres true thickness on 25 metre drill spacing. Step-out drilling thus far has shown a diminution of mineralization within 25 metres on three of the four sides with possible continuity as far as 100 metres further east. This lozenge of mineralization appears similar to locally thicker areas of "pinch and swell" mineralization within the historic mine area. Continued step-out drilling of this feature continues.
Office Block Extension:
Seventeen boreholes in the Office Block Extension intersected mineralization up to 2.24 metres true thickness on 25 metre drill spacing. The boreholes are located beneath the temporary administration camp situated approximately 330 metres east of the main mine development area and approximately 200 metres east of the thick mineralized zone in the mid-Eastern Flats. Step-out drilling continues along strike and down-dip in this area as the extent of mineralization remains open in all directions.
