Great Western Minerals Significantly Upgrades Mineral Resource
Estimate for Steenkampskraal Rare Earth Project
SASKATOON, CANADA--(Marketwired - Nov 12, 2013) - Great
Western Minerals Group Ltd. ("GWMG" or the "Company") (TSX-VENTURE:
GWG) (OTCQX: GWMGF), a leader in the manufacture and supply of
rare earth element-based metals and metal alloys and holder of a
low cost, high-grade critical rare earth asset, today announced
that its new NI 43-101 compliant technical report and mineral
resource estimate ("MRE") for the Steenkampskraal rare earth
project ("SKK") shows a significant increase of tonnes in the
Indicated category and the addition of newly defined tonnes in the
Measured category. Overall, the size of the resource has
increased compared with the Company's previously released mineral
resource estimate dated December 2012.
Highlights of the MRE are as follows (resource estimates
based on 1% cut-off grade):
- 16,600 tonnes total rare earth oxides including yttrium oxide
("TREO") from the in situ resource now report to the Measured
category
- 67,000 tonnes TREO in the in situ Indicated category, an
increase of 38,200 tonnes
- All tailings now report to the Indicated category for a total
of 46,000 tonnes surface material hosting 3,300 tonnes TREO at a
lower grade of 7.18% compared with the December 2012 MRE, due to
the combination of the two historic tailings dams and addition of
low radioactivity materials recovered during site
clean-up
- Overall increase of 171%, or 54,800 tonnes TREO, in the in situ
and tailings Measured and Indicated categories to 86,900
tonnes
Company President and CEO Marc LeVier stated, "A significant
increase in assay data from core drilling and underground sampling
at SKK during the last year has provided input for a new resource
estimate. The results of the MRE show an increase of total
rare earth oxides including yttrium oxide bringing the total in
situ and tailings Indicated and Measured resource to 86,900 tonnes
TREO. We also saw a substantial upgrade of the previous
Inferred resource component to the Indicated category or better,
and increased the overall tonnes of TREO that are candidates for
conversion to formal reserves."
The new MRE on the SKK project, which has been prepared by
Snowden Mining Industry Consultants Inc. ("Snowden"), is dated
effective October 31, 2013 and will be filed and available under
the Company's SEDAR profile at www.sedar.com within 45 days.
For its new MRE, the Company provided the additional information
shown in Table 1 beyond that utilized in the mineral resource
estimate dated December 31, 2012. This additional information
contributed to increasing the data density and the extent of
mineralization both along strike and down-dip.

Table Notes:
- TREO refers to total rare earth oxides plus yttrium oxide.
- Grades for in situ Mine and Exploration area for each resource
category are "as reported" from datamine modelling.
- Material tonnes were rounded to three significant figures.
- Metal tonnes for TREO were rounded to nearest hundred
tonnes.
- For the Oct 2013 MRE, grades were rounded to two decimal
places. Apparent errors may result due to rounding.
- The metal tonnes for Indicated and Inferred totals were
calculated by summing the metal tonnes of each category in each
area.
- The grades for Indicated and Inferred were calculated by
dividing the metal tonnes by the tonnage as reported by datamine
modelling.
- Resource estimates based on a cut-off of 1% TREO.
Geology and Mineralization The SKK mineralization consists of a
narrow, shallow and irregular dipping (from 10° to 60° to the
south), pinch and swell monazite vein, which is exposed at surface
as an east-west striking body. It has an average true
thickness of about one metre ("m"), varying from less than two
centimetres ("cm") to just over ten metres. The vein has been
traced for a strike-length of over 1,050 m and a known southerly
down-dip extension of up to 150 m. The current MRE covers the
full known strike-length. The vein structure exhibits
reasonably good lateral and vertical continuity, although the known
mineralization is dissected by several fault structures of varying
orientation, some of which have resulted in vertical and lateral
displacements of one metre to tens of metres. Based on
drilling results since 2011, which targeted shallow mineralization
to a depth of approximately 150 m, mineralization currently is
closed along strike in both directions and locally
down-dip. However, the interpretation in the structural
geology model supports the potential for an extension of
mineralization beyond the known east and west bounding faults.
Mineralogical investigations indicate that the vein is composed
predominantly of the mineral monazite, which accounts for more than
91% of total rare earth elements, with much lesser amounts of rare
earth element-bearing allanite, thorite, and
xenotime. Alteration minerals are dominated by quartz,
Fe-chlorite, magnetic Fe-oxide minerals, ilmenite, and sulphides
including chalcopyrite, pyrite and galena. Vein material at
SKK contains from 0.4% to 46% TREO, with the average grade
typically dependent on the amount of diluting materials (such as
quartz, feldspar, magnetite and sulphides) within the vein
structure.
Exploration The historic SKK mine has been partially
rehabilitated by GWMG and all three access levels and most of the
old workings remain open to geological and geotechnical
investigations. Evaluation and exploration work from September
2011 to March 2013 consisted of surveying, mapping, and sampling
232 HQ and NQ surface drillholes totalling 27,977 m within the mine
and adjacent exploration areas along strike and down-dip, and 102
underground channels within the historic mine workings. In
addition, GWMG undertook evaluation drilling and sampling of the
historic tailings dams. The rock dump has also been sampled,
but was not included in this MRE.
Survey information, intercept thicknesses, lithological
descriptions, density measurements, scintillometer readings and
assay results for 1,626 samples were included in evaluation of
mineral resources in this MRE. In comparison with the December
2012 resource estimate, no calculated grades resulting from
correlation of scintillometer data to assay results were
utilized. Drillhole fence lines are oriented along down-dip
lines perpendicular to strike on nominal 25 m to 50 m line spacing,
and 25 m collar centers. Of the 232 drillholes reviewed by
Snowden, 69 did not intersect the zone of
mineralization. These reported "misses" represent either
drilling beyond the vein boundaries, local areas of
non-mineralization within the vein system that may be related to
"pinch and swell," or to areas of structural
displacement. Many of the misses were incurred during step-out
drilling while searching for extensions of
mineralization. Areas of mineralization bounded by faults with
displacement were used to domain the zones of mineralization for
greater control and confidence in the resource estimate
methodology.
Quality Assurance / Quality Control The validated database for
the MRE includes information on 1,079 core samples, 277 in situ
underground samples, and 290 tailings samples. Drill holes
that did not contain assay data were included as they provided
lithological information for the wireframe modeling.
SGS Canada conducted the assay testing. Snowden examined
the assay data of the blanks, certified reference materials, and
field duplicates to verify and assess the reliability of the
overall assay dataset, and to assist in the determination of the
robustness of the resource estimation. The addition of quality
control samples for core, channel and tailings samples amounts to
19% of overall rare earth assays. It was concluded by Snowden
that the addition of reference material and blanks to the SKK
sample batches was sufficiently adequate.
Modelling and Estimation Method The mineralized zone wireframe
representing the mineralized zone was generated using Leapfrog™
software after much verification work, and guided by the available
geological information. All of the assay intervals falling
within the mineralized zone were composited to the dominant sample
length of 0.5 m.
Establishment of Block Models and Variography Analysis The
interior of the mineralization wireframe was populated with blocks
measuring 10 m by 10 m by 0.5 m using Datamine™ Studio version 3
software. Sub-blocking was used to provide for a more accurate
volume determination; the smallest dimension for sub-blocks being
1.25 m by 1.25 m by 0.1 m. No rotation of blocks was applied
as the strike and dip of the monazite was honored through the small
dimensions of sub-blocking.
Variograms were generated for each of the rare earth oxides
("REOs"), as well as yttrium, thorium and uranium, only using the
assay data from the mineralized zone. Two structured
(exponential first structures and spherical second structures)
directional variograms were modeled. Down-hole variograms were
calculated and modeled to determine the nugget variance for the
variogram models. The data occurring within the wireframes
were combined for the domained zones to generate more robust
variograms. All variograms were modeled on normal scores
transformed data and back-transformed prior to their use in grade
estimation. The variograms showed well developed structure and
long ranges.
The block model comprises blocks of 10 m by 10 m by 0.5 m with
sub-blocks down to 1.25 m by 1.25 m by 0.1 m in order to honor the
attitude and shape of the mineralization.
Grade Interpolation Parameters Block grades for the individual
REOs, yttrium, thorium and uranium were estimated using ordinary
kriging. The six domains used for modeling were delineated
based on the location of major faults, and a small area of
complexity characterized by bifurcation or interleaving of monazite
veins. The zones were estimated separately and individual
block models combined for classification.
TREO%, LREO% and HREO% (each as defined in Table 3) values,
which were calculated for reporting by combining the estimated
grades of the individual REOs, were also estimated in the block
model as a check to ensure the preservation of the total package
and for validation, but these were not reported.
A strong correlation was observed between density measurements
and TREO% values. A linear regression was therefore used to
define a relationship between density and TREO%, and subsequently
used to estimate density values into the block model using the
estimated TREO% grades in each block.
The block model was depleted for 'past production' using current
survey information pertaining to the underground development and
mined-out areas. This ensured that parts of the model
representing stopes and development workings were not included in
the resource estimate.
Classification of the mineral resource took into consideration
data quality (including location information), confidence in the
structural framework, and confidence in the resource
estimate. This has been adjusted following the 2012 estimates
based on the acquisition of new data as well as improved confidence
in the geological framework following the recent structural geology
interpretation.
Resource Estimate for the Tailings Dams In December 2012,
Snowden completed a mineral resource estimate of the tailings dams,
which was reported with the December 2012 mineral resource
estimate. During mid-2013, the Company moved and combined the
tailings material (25,340 m3) to an alternate location. The
new tailings dam volume, including the surrounding berm, is 31,269
m3.
It was not possible to attribute the grades of the December 2012
tailings dam grade models to any discrete portion of the new dam or
berm, due to commingling of material sourced from the original
tailings dam mixed with contaminated soil. It must be
considered that the tailings are now all mixed, and the average and
diluted grade be applied to the whole.
The December 2012 estimate of the tailings mineral resource
comprised 24,560 m3 (36,600 tonnes) at 8.8% TREO+Y2O3 of Indicated
Resource, and 780 m3 (1,200 tonnes or around 4% of the tailings) at
7.5% TREO+Y2O3 of Inferred Resource.
For reporting of the tailings mineral resource, the grade of the
tailings was therefore combined and factored by 0.81
(0.81=25,340/31,269, representing the ratio of volumes) so that the
grade of the overall tailings is now reported as 7.18%
TREO+Y2O3. This assumed the density remains unchanged, so the
metal content is preserved. If the density is decreased, or
GWMG is able to segregate tailings from waste, then the tonnage
will decrease and the grade will increase, but the estimated metal
content will remain unchanged. This grade is consistent with
grab samples from the tailings.
The Indicated and Inferred portions cannot now be separated, and
therefore Snowden took the stance to include the entire tailings
resource in the Indicated category. Snowden elected to
maintain the classification of the tailings resource as an
Indicated mineral resource because of the certainty that all of the
tailings were relocated, the added dilution is added with a zero
grade, the subsequent average grade is well above cutoff, and the
dump will be treated as a part of the environmental cleanup if the
project succeeds in development into a producing mine.

Table Notes:
- Material tonnes were rounded to 3 significant figures.
- The metal tonnes for Indicated and Inferred totals were
calculated by summing the metal tonnes of each category in each
area.
- Grades for in situ Mine and Exploration area for each resource
category are "as reported" from datamine modelling.
- Grades were rounded to 2 decimal places with exception to
Tm2O3, Lu2O3 (which were rounded to 3 decimals).
- Rare Earth Oxides ("REO") may be divided into Light Rare Earth
Oxides ("LREO") and Heavy Rare Earth Oxides ("HREO"). The
LREOs comprise lanthanum ("La2O3"), cerium ("CeO2"), praseodymium
("Pr6O11"), neodymium ("Nd2O3") and samarium ("Sm2O3") and the
HREOs consist of europium ("Eu2O3"), gadolinium ("Gd2O3"), terbium
("Tb4O7"), dysprosium ("Dy2O3"), holmium ("Ho2O3"), thulium
("Tm2O3"), ytterbium ("Yb2O3") and lutetium ("Lu2O3"). Yttrium
("Y2O3"), thorium ("ThO2") and uranium ("UO2") are also included in
the oxides estimated.
- For the purposes of this table, HREO does not include Y2O3
