Due to growing global competition, the mining industry has suffered significant share of losses and the mining industry in Ghana is no exception. Lean operations and maintenance is a widely accepted and adopted approach across many industries and this concept has not been tested in a Ghanaian situation. The Process Maintenance section of the Processing Department was studied to identify the successes, failures, and challenges of lean maintenance implementation, in the areas of maintenance system, rework and maintenance cost. Qualitative and quantitative measures were used to document and compare the individual case studies. Both primary and secondary data on the Processing Plant of Newmont Gold Ghana Limited was used to analyze the effects and benefits of the lean maintenance implementation in a pre and post comparison. Findings of the study showed that Newmont Gold Ghana Limited was able to reduce reworks (defects), plant down time, and maintenance cost and all these reductions added to the total improvement in the company’s operations. The general observation also revealed the need for a continuous training of workers on ways in improving lean maintenance culture.
