Beatrix Gold Mine
Technical Short Form Report
The Beatrix Gold Mine consists of four surface operating shafts that mine various gold
bearing reefs from open ground and pillars at depths between 600 and 2,155 m below
surface. Ore is processed at two metallurgical plants with mill throughput of approximately
3.0 Mtpa to produce approximately 391 koz of gold. The mine has a workforce of
approximately 10,500 employees.
The geological and evaluation models for F2010 have been updated to reﬂect the latest
available data. These models are coupled with an integrated and holistic mine design and
schedule plan that is based on current performance levels.
This Technical Short Form Report reﬂects the latest Life of Mine plan, together with an
updated Mineral Resource and Mineral Reserve statement, as at 30 June 2009. All Mineral
Resource and Mineral Reserve ﬁgures reported are managed unless otherwise stated and
Mineral Resources are inclusive of Mineral Reserves.
In summary, the Beatrix Mineral Resource base has increased by 9% year-on-year.
The overall Mineral Reserve base has however, decreased slightly by 4% since the June
2008 Mineral Reserve declaration. Signiﬁcantly increased power, consumable and labour
costs have offset increased gold price revenues, with the effect that only nominal reductions
in year-on-year paylimits were realised.
• Mineral Resource at 17.6 Moz.
• Mineral Reserve at 6.4 Moz.
• Focus is on developing the West Section as a high grade, steady state
and sustainable production unit.
• Drive on surface and underground exploration to increase resource
deﬁnition, especially in project areas.
• The Beatrix LoM plan extend to 2022.
Beatrix is the southernmost mine in the Witwatersrand Basin and has shown that low grade ore
deposits can be proﬁtably mined with corresponding high levels of safety and productivity.
The discovery and development of the Free State Goldﬁelds can be traced back to 1885.
After intense exploration, which started in 1936, three gold bearing conglomerates were identiﬁed
in 1938. Further drilling led to the identiﬁcation of the Basal Reef in March 1939, which led to a
score of mines being developed in the Free State Goldﬁelds.
Beatrix dates back to 1985 when mining ofﬁcially started and today comprises one mine after the
incorporation of the Oryx mine, which had been renamed Beatrix 4 Shaft (West Section).

General Location Beatrix Mine is situated in the Magisterial District of Matjhabeng, at latitude 28° 15’ S and longitude 26° 47’ E
near the towns of Welkom and Virginia, some 240 km southwest of Johannesburg, in the Free State Province of
South Africa. The site is accessed via the N1 highway between Johannesburg and Kroonstad, and then via the
R34. Geologically it is located in the Free State Goldﬁeld and is the southernmost mine in the Witwatersrand Basin

Structurally, the Free State Goldﬁeld lies
within a north-south trending syncline forming
an apex in the south-western corner of the
Witwatersrand Basin. The Central Rand Group
in the Free State comprises some 2,000 m of
discrete sedimentary sequences deposited
over successive unconformity surfaces in an
expanding depositional basin. The paucity
of major faulting and folding of Central Rand
Group age has led to the conclusion that
subtle tectonic warping of the basin with
granite doming on the margins controlled
deposition. The conglomeratic reef units are
most commonly deposited at the base of each
depositional sequence, although gold may
also occur as scours within a given formation.

Mineral Resources and Mineral Reserves
The Beatrix Mineral Resource and Mineral Reserve declaration is based on systematic and sustainable mineral reporting practices. Systematic
geological mapping and drilling consistently updates geological structurel and facies models, which are used as the basis of each declaration.
On-going sampling of all development and stoping on a grid basis is carried out to provide additional data that is incorporated into a detailed
Updated mine designs and schedules are then compiled and evaluated based on the most recent technical-economic models to compile a LoM plan
for each operational shaft, taking note of infrastructural capacities, limitations and the need for any additional infrastructure requirements. Detailed
economic and scenario models are subsequently completed to ensure validity of positive cash ﬂow for Mineral Reserve declaration purposes. Peer
review as well as internal and external audits, ensure consistency and compliance to regulatory practices.
Beatrix’s Mineral Resource and Mineral Reserve are reported within its mining right and are adjusted to show the split between above (AI) and below
(BI) current shaft infrastructure.
Mineral Resources are quoted at an appropriate in-situ economic cut-off grade with tonnages and grades based on the resource block model,
which include estimates of any material below the cut-off grade required to be mined to extract the complete pay portion.

Mineral Reserve estimation at Beatrix is based on the development of an appropriately detailed and engineered LoM plan, which accounts for all
necessary access development and stope designs. All design and scheduling work is undertaken with mine planning software. The planning process
incorporates appropriate modifying factors and the use of cut-off grade policies and technical-economic investigations.
