Exploration and Innovation The Discovery and Evolution of the 2Moz Vogue Gold Resource, Sunrise Dam Gold Mine, Western Australia M Nugus1,2, N Oliver3, T G Blenkinsop4, J Hill5, J G McLellan6, JCleverley5, L Fisher5, N Brunacci7, H Moore8 and A Jenkins9 ABSTRACT The 2 Moz Vogue mineral resource is a recent discovery at the Sunrise Dam gold mine (SDGM), lying approximately 600 m vertically below the Sunrise Dam open pit. Unlike most other lodes, which are dominated either by steep vein sets or shallow high-strain (shear) zones, it lies broadly in the hinge of a folded felsic porphyry body, where it cuts intermediate volcanic lavas and volcaniclastic rocks and is not speciÀcally concentrated at a lithofacies contact. The mineralisation is controlled by a complex interplay of moderate to shallow, west-dipping high-strain zones that are transected by irregular and discontinuous high-grade, north-west-, north–south- and east– west-trending breccia sheets that initially caused problems with attempts to model broad domains. However, by combining the structural controls and styles with the distribution of gold, arsenic, sulfur and antimony, we have improved opportunities for scheduling, extracting and processing the most appropriate material considering the current mining and processing constraints. The early delineation process for the Vogue lode revealed a signiÀcant mineral resource for the SDGM, coupled with the recognition of some potentially difÀcult downstream implications for mining and processing. The ultimate success of mining at Vogue will be a consequence of combining standardised data collection and geological modelling techniques with the results of the novel innovative techniques applied at an early stage of the project. -

Modelling the Optimum Interface Between Open Pit and Underground Mining for Gold Mines
MODELLING THE OPTIMUM INTERFACE BETWEEN OPEN PIT AND UNDERGROUND MINING FOR GOLD MINES Seth Opoku A thesis submitted to the Faculty of Engineering and the Built Environment, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy. Johannesburg 2013 DECLARATION I declare that this thesis is my own unaided work. Where use was made of the work of others, it was duly acknowledged. It is being submitted for the Degree of Doctor of Philosophy in the University of the Witwatersrand, Johannesburg. It has not been submitted before in any form for any degree or examination at any other university. Signed …………………………….. (Seth Opoku) This……………….day of……………..………2013 i ABSTRACT The open pit to underground transition problem involves the decision of when, how and at what depth to transition from open pit (OP) to underground (UG). However, the current criteria guiding the process of the OP – UG transition are not well defined and documented as most mines rely on their project feasibility teams’ experiences. In addition, the methodologies used to address this problem have been based on deterministic approaches. The deterministic approaches cannot address the practicalities that mining companies face during decision-making, such as uncertainties in the geological models and optimisation parameters, thus rendering deterministic solutions inadequate. In order to address these shortcomings, this research reviewed the OP – UG transition problem from a stochastic or probabilistic perspective. To address the uncertainties in the geological models, simulated models were generated and used. In this study, transition indicators used for the OP - UG transition were Net Present Value (NPV), ratio of price to cost per ounce of gold, stripping ratio, processed ounces and average grade at the run of mine pad. -
Influence of Structural Setting on Sulfur Isotopes in Archean Orogenic Gold Deposits, Eastern Goldfields Province, Yilgarn, Western Australia

As for orogenic gold deposits worldwide, most deposits have positive means and a restricted range of δ34S values, but some have negative means and wider ranges of δ34S values. Wall-rock carbonation and back-mixing of similar- source fluids with different fluid pathways can explain some of the more negative δ34S signatures. However, structural setting appears to be the most important factor controlling ore-fluid oxidation state and hence the distribution of δ34S values in gold-related pyrites. Shear-hosted deposits appear to have experienced fluid-dominated processes such as phase separation, whereas stockwork, vein-hosted or disseminated deposits formed under conditions of greater rock buffering. At Victory-Defiance, in particular, negative δ34S values are more common in gently-dipping dilational structures, compared to more compressional steeply-dipping structures. -

P90 AngloGold Ashanti Annual Financial Statements 2009 AngloGold Ashanti’s sole operating asset in Australasia is Sunrise Dam. The group also has an extensive exploration programme under way in Australasia, the most advanced of which is Tropicana, a joint venture in which AngloGold Ashanti holds 70% and the Independence Group NL has 30%. Tropicana is managed by AngloGold Ashanti and covers 13,500km2 of tenements. This project is the focus of the group’s exploration activities in Australasia. Exploration in the Australasia region is also currently being conducted in the Philippines and the Solomon Islands. Further information on the progress being made here is presented in the Exploration review on page 114 of this report. In January 2009, AngloGold Ashanti agreed to sell its 33.33% interest in the Boddington project in Australia to joint venture partner, Newmont Mining Corporation. This project is therefore not covered in this report. The Australasian operation produced 401,000oz of gold in 2009, equivalent to 9% of total group production.

2008 Minerals Yearbook GOLD
2008 Minerals Yearbook GOLD U.S. Department of the Interior October 2010 U.S. Geological Survey GOLD By Micheal W. George Domestic survey data and tables were prepared by Wanda G. Wooten, statistical assistant, and the world production table was prepared by Linder Roberts, international data coordinator. In 2008, domestic mine production of gold decreased to RI, areas, with other manufacturers in California, Florida, and 233,000 kilograms (kg), slightly less than that of 2007 (tables Texas. In 2008, the estimated percentages for end use of gold 1, 2). This marks the eighth year in a row that production has were jewelry and arts, 72%; dental and medical, 11%; electrical dropped and was 36% lower than the historical high of 366,000 and electronics, 7%; and other, 10%. kg in 1998. In 2008, the value of domestic production increased Trade in refined bullion comprised 51% of U.S. gold imports to $6.550 billion, up 22% compared with that of 2007 because and 81% of exports; the United States was a net exporter of of the increase in the price of gold. It was the seventh straight 342,000 kg of bullion in 2008. The increase in exports was year that the value had increased. Production from the major caused by an increase in price and an increase in investments mines in Nevada was lower as a result of mining lower grade outside the United States. Canada and Mexico provided almost ore, closure of two mines, and companies concentrating on mine 71% and 10%, respectively, of the refined bullion imported, development instead of gold production. -
