Wits Gold is pleased to announce the completion of a positive
pre-feasibility study (“PFS”) on its De Bron – Merriespruit (“DBM”)
Project, situated south of the mined out Merriespruit Gold Mine, six
kilometres south of the town of Virginia in the southern Free State
goldfield, South Africa. The study has illustrated that mining at DBM
is both technically and economically viable. Wits Gold owns 100% of the
Prospecting Rights to the DBM Project. The PFS was completed under the
guidelines of the South African Code for Reporting of Mineral Resources
and Mineral Reserves (“SAMREC Code”) as well as the Canadian National
Instrument 43-101, and was undertaken by the independent consultants,
Jim Pooley and Jon Hudson (“the Qualified/Competent Persons”), from
Turgis Mining Consultants (“Turgis”). These independent
Qualified/Competent Persons have approved the technical contents of
this news release. A National Instrument 43-101 compliant technical
report is being finalised and will be filed on SEDAR within 45 days of
this news release.

The DBM deposit contains an estimated Indicated Mineral Resource of
41.8Mt at an average grade of 5.5g/t gold (7.5Moz). This Resource was
estimated at a cut-off gold value of 300cm.g/t for the Beatrix,
Kalkoenkrans, B and Leader Reefs where a three-dimensional geological
model illustrated that these conglomerate reefs occur at depths between
480 and 1 350 metres below surface. This Mineral Resource Estimate was
previously disclosed in the National Instrument 43-101 technical report
entitled “Witwatersrand Consolidated Gold Resources Limited: Mineral
Properties in the DBM Project, South Africa” dated February, 2012. This
technical report is available at www.sedar.com and on the Company’s website. The Mineral Resource Estimate was
prepared by George Gilchrist, who is a full time employee of Snowden
Mining Industry Consultants (“Snowden”) and independent of Wits Gold.
Mr Gilchrist is a Qualified Person as defined by National Instrument
43-101. Mr Gilchrist is a registered Professional Natural Scientist
(“Pr.Sci.Nat”) with the South African Council for Natural Scientific
Professionals (SACNASP) and has more than six years of experience in
gold exploration and mineral resource estimation.

The PFS was intentionally based on that portion of the Resource which is
generally less than 1 000 metres below surface and which contains an
Indicated Mineral Resource of 26.7Mt at 5.8g/t gold (4.99Moz). Applying
the geological model, the PFS considered a number of alternative
primary access configurations, mine designs and production profiles.
The results from these production schedules were subsequently input
into a series of financial models in order to compare the potential
returns from each of these options. Based on these results, two options
have been selected for further investigation prior to the commencement
of a feasibility study.

The first option (“Option 1″) is based on standard conventional breast
mining practices in the Witwatersrand Basin, while the second option
(“Option 2″) investigates a semi-mechanised variation of the down-dip
mining methodology currently practised in the platinum mining industry
of the Bushveld Complex. For both options it is envisaged that a twin
shaft system will be sunk to 660m with top production level commencing
on 560m, from where a twin decline system will provide access to the
deeper parts of the ore body.  For both options the off-reef
infrastructure has been developed using trackless mechanised equipment
to facilitate a rapid production build up with conventional on reef
development in order to minimise dilution. A system of off- reef
trackless footwall haulages are developed on strike below the ore
body.  For Option 1, cross-cuts to reef will be spaced at 180 metres
with on-reef raises and conventional breast stoping completing the

Option 2 differs from Option 1 in that the on-reef development and
mining is done on dip as opposed to on strike. The mining method for
Option 2 involves closely spaced pre-developed on reef raises (spaced
30m apart) which improves orebody understanding and allows for
selective mining and improved gold extraction. The mine design for
Option 2 is flexible and amenable to alternating between conventional
and long hole stoping. The advantage of the long hole stoping method is
that, where applicable, it allows for the mining of a narrower channel
which will have the effect of an increased head grade. Wits Gold
considers that Option 2 therefore has the potential for improved safety
through a better understanding of the orebody, and a potential
reduction in the number of workers on the rock face. The hybrid mining
methodology, alternating between conventional and long hole mining,
warrants further investigation prior to the feasibility study.

The Company, together with Turgis, recognise that the long hole
variation to the dip mining technique for Option 2 is as yet not an
established gold mining practice for the Witwatersrand Reefs and it has
therefore not been used for the conversion of Indicated Resources to
Probable Reserves. Instead, the conversion of Indicated Mineral
Resources to Probable Mineral Reserves results from the application of
modifying factors using the conventional mining method in Option 1.

The following tabulation summarises the planning process followed to
progress from the Indicated Resource used in the PFS mine design to the
Probable Reserve. Note that the Probable Reserve is included in the
Indicated Mineral Resource.

*The Indicated Mineral Resource included 4% geological losses

**Mine Call Factor planned at 90%

This Reserve calculation is based on an underground mine layout for DBM
that will require a total life of mine capital expenditure of ZAR5.4
billion (approximately US$680.4 million) including ZAR144.6million
(US$18.1 million) for Stay-in Business (SIB) capital. However, peak
initial funding will be considerably lower at ZAR2.4 billion (US$ 295.8
million). It is estimated that the operating cost will be R629/tonne
(US$78.6/tonne), whilst first reef production could be achieved 47
months after the commencement of shaft sinking.  Mineral Resources that
are not Mineral Reserves do not have demonstrated economic viability.

The ore will be delivered to an on-site carbon-in-leach gold recovery
plant that will recover 96% of contained gold delivered to the plant.
Including a five-year ramp-up period, the mine is expected to operate
for 18 years with an average annual production in excess of 200 000oz
of gold and cash costs estimated at US$628/oz.

A number of financial alternatives have been estimated for PFS Options 1
and 2. The NPV and IRR are pre-tax and after 5% royalty. Based on
different gold price scenarios the results of this exercise are as

    |           |Gold price|        |        |        |        |        |
    |           |  per kg  |R300 000|R350 000|R400 000|R450 000|R500 000|
    |Option 1   |IRR       |15.3%   |22.2%   |28.0%   |33.1%   |37.6%   |
    |           |NPV (5%)  |R2 553m |R4 903m |R7 275m |R9 651m |R12 030m|
    |Option 2   |IRR       |19.4%   |25.6%   |30.9%   |35.5%   |39.7%   |
    |           |NPV (5%)  |R4 602m |R7 356m |R10 145m|R12 942m|R15 739m|

At a gold price of R400 000/kg (US$1 555/oz at R8.00 per US$) and a
state royalty of 5% on revenue, Option 1 has an IRR of 28.0% and an NPV
(5%) of R7.3 billion (US$909 million), while Option 2 has a potential
IRR of 30.9% and an NPV (5%) of R10.2 billion (US$1.3 billion). The
financial results for Option 2 are at this stage only considered to be
indicative of the potential as further analysis needs to be done on the
down-dip mining method. Based on the improved IRR values as well as the
potential safety benefits, it is the intention of the Company to
thoroughly research the viability of the down-dip mining method during
the feasibility study stage.   

A sensitivity analysis of the major input variables as shown below
indicates that the financial model for DBM is most sensitive to gold
price and grade.

The conversion of Indicated Resources to Probable Reserves was made on 8(th) June 2012 based on the Indicated Resources quoted in the February 2012
NI 43-101 technical report by Snowden Mining Industry Consultants Inc.
(“Snowden”). The Indicated Resource declared by Snowden considered a
geological loss of 4% to account for minor faulting and
sedimentological factors as per the Snowden February 2012 report.
Furthermore it was also recognised that certain portions of the reefs
would for geotechnical reasons not be mined due to the small vertical
separation between them.

The modifying factors used for the conversion of Indicated Mineral
Resources to Probable Mineral Reserves include waste dilution of 28%
and planned ore extraction losses of 18%. This includes dilution from
stoping, in-stope gullies and on-reef development and allowances for
geotechnical constraints, a minimum mining width of 90 centimetres,
minor geological losses (4%) and a Mine Call Factor of 90%. This
process resulted in the definition of an estimated Probable Mineral
Reserve of 23.5Mt at a plant head grade of 4.05g/t gold, containing
3.1Moz of gold. No Inferred Mineral Resources were included in the
conversion of Resources to Reserves.


Wits Gold holds 14 new order Prospecting Rights over 1 195km(2) in the southern Free State, Potchefstroom and Klerksdorp goldfields.
The Company is currently focused on fast-tracking two advanced
projects, DBM and Bloemhoek, located next to each other in the southern
Free State goldfield and adjacent to the Beatrix gold mine operated by
Gold Fields, and the Joel gold mine operated by Harmony. On 22 February
2012 the Department of Mineral Resources accepted the Company’s
application for a Mining Right for gold, silver and uranium over its
advanced Prospecting Rights areas in the southern Free State goldfield,
which include the DBM, Bloemhoek, Robijn and Hakkies Project areas. The
granting of the Mining Right is expected over the next 12 months, once
the Company complies with requirements in terms of the Minerals Act,
such as obligations in terms of feasibility studies, environmental
impact assessment as well as Social and Labour Plan commitments. Once
granted, a Mining Right is valid for a period of 30 years and renewable
for a further period as required.
