Martabe Project 3D Animation
The Martabe Mine is established under a sixth generation Contract of Work (“CoW”) and covers 1,639 km2 along 110 km of strike length adjacent to the Sumatra fault. The resource base includes 8.1 million ounces of gold and 73.8 million ounces of silver and there are six known deposits within a 30 km2 area with Purnama the largest so far. Martabe celebrated the first anniversary of commercial gold production from the Purnama pit in July 2013 and to date has exceeded ramp-up expectations. Martabe is anticipated to produce in excess of 250,000 ounces of gold and 2-3 million ounces of silver per annum for a minimum of 10 years, based on the current ore reserves. Production expansions and life of mine extensions will be targeted from: optimising the mine and process plant, oxide debottlenecking and expansion, a sulphide ore treatment process plant and further discoveries on the CoW.
Martabe benefits from a competitive estimated life-of-mine cost structure for the Purnama pit. The low cost structure is a result of the capacity and size of the project, the shallow nature of the Purnama deposit that results in a low strip ratio of 0.8:1, the good grade of the ore and straightforward gold extraction process. In addition, Martabe benefits from the advantageous location of the project, being close to highways, airports, port, power and a significant national skilled human resources pool.
The Martabe operation encompasses the Purnama open pit mine, a conventional processing plant with 4.5 Mtpa capacity, a permanent accommodation facility for mine workers, haulage roads, high voltage switchyard, onsite workshop and warehousing, and a tailings storage facility with associated water catchment and diversion systems. Safety is the highest priority for G-Resources this is evident in the Company’s outstanding safety results.
