Mineral resource is a concentration of a mineral or minerals which are found in a shape and amount so that it can be exploited economically. These resources are commonly characterised with their grades and tonnages. Resource estimation refers to estimation of tonnage and grade. Resource estimation is the most important step of evaluating a mineralization. Resorce estimates are used in making decisions about opening up a new mine or planning future investments for an operating mine. There are many methods used in industry for the purpose of resource estimation. Kriging is a widely used method among them. However it underestimates high values whereas overestimates low values and therefore leads to a smoothing in estimation. In this thesis, an hybrid method that combines unbiasedness property of kriging and spatial variability property of simulation is used. This method can also be used for the estimation of ore deposits which consist related multi variables. For this pupose, some functional codes are included in the main program and the developed method is named as “Covariance Matching Kriging (CMK)”. The CMK method and the other known methods are aplied to different real cases obtained form drill hole logs and the results are evaluated comparatively.
