After accounting for mining depletion, Maritana Minerals has delivered a significant boost to its gold inventory, boosting its gold ore reserves in WA by a whopping 148 per cent to 204,000 ounces and hiking its total combined mineral resource to 1.86 million ounces of gold, up by 6.6 per cent on a year-on-year basis. The growth was driven by the company's maiden reserves at its Crake and Kalpini projects.
