Gold Fields Ghana Limited (GFGL) has several gold mining concessions situated in Ghana with granted Mining Leases of which the Teberebie Mine is an essential part and still in production. The Teberebie Mine which is found within the Takwaian district is located some 70 km north of the city of Takoradi, and 10 kilometres south-west of Tarkwa. The Mantraim central project known as "Mantraim Central" is a part of the main Mantraim project which has been drilled extensively to grade control. It is the main target area of the project under study, the objective of which is to evaluate the ore resource of the central portion of the Mantraim project based on the 50 m x 50 m drill spacing to determine if the prospect has been underestimated or overestimated and the possibility of continuity of the ore deposit at deeper depth. The ore body strikes virtually north – south and dips 10 – 180 E. Using the ordinary kriging methodology, a total of 486,119 gold ounces of indicated resource covering 15 million tonnes of oxide ore material at an average grade of 1.02 g/t Au was realised from the model. Ordinary kriging was used to define the mineral resources of the deposit due to the nature and the amount of data that were available for estimation in the project area. To verify this, first a kriging estimate of the local mean was set up, and then a simple kriging estimator using this kriged mean was performed.
