Competitiveness of Inverse Distance Weighting Method for the Evaluation of Gold Resources in Fluvial Sedimentary Deposits: A Case Study. Correlation analysis performed on ID 2W and OK model grades indicated a near perfect correlation coefficient of 0.93 an indication that ID 2W can be used as a good alternative to OK at Pepe. This study seeks to verify the propriety and applicability of IDW to the estimation of the orebody by comparing the estimates obtained from Inverse Distance Weighting (IDW) and Ordinary Kriging methods. Inverse Distance Weighting (IDW) is another reliable method of estimation as it is simple, accurate and fast, and has proven to be effective for some deposits. Although the mine employs Ordinary Kriging (OK), which has gained much recognition and proven to be a very good estimator, it is complex and time consuming. The selection of the method used for any particular deposit depends on several factors including easeāof-use, robustness, accuracy and precision.

There is therefore, the need for the application of an appropriate, accurate and cost effective estimation method. Due to cut-back, further exploration has been done to obtain credible resource estimates for pragmatic mine planning and design.

Gold mineralisation at Pepe occurs in a sedimentary sequence known as the Banket Series formation.
