W e can take your project from grassroots exploration through the feasibility study stage and into production. Our approach to resource estimation combines our strengths in structural geology and ore deposit geology , our understanding of geostatistical theory and our extensive resource estimation and mining operational experience. While each resource estimate is tailored to each specifc project, our general procedures typically include: • An assessment of the quantity and quality of the data available including database management and verifcation • The creation of 2D and/or 3D geological and mineralisation models for the deposit • Statistical and geostatistical analyses of the data and the determination of the most appropriate grade and density interpolation methods • Classifcation and reporting according to accepted internationally recognised codes W e have a large skills base and extensive experience in the use of all the major geological modelling and geostatistical packages. Notably , the original Gemcom software was developed within SRK while more recently the Leapfrog software has been developed under a joint venture agreement with Applied Research Associates of New Zealand. This gives SRK the fexibility to continue the use of the software that you are currently using or select the most appropriate software for new projects. W e have experience in developing and reviewing geological models and resource estimates for all commodities and deposit types. W e also have a large base of competent / qualifed persons as defned by the various internationally accepted resource reporting codes. Sino Gold Project: Jinfeng, China. Scope: Resource estimation for a structurally controlled gold project requiring selective mining via open-pit and underground methods. Outcome: Uniform conditioning was applied to the open-pit material, allowing an estimation of the distribution of mineable economic grade material within the larger resource blocks. A conditional simulation approach was utilised for the underground mining, stope size blocks were directly estimated and the levels of risk in each evaluated. Ser vices
