The company recently announced that it has achieved several significant milestones: According to Chris Evans, managing director of Birimian, an independent, third-party review of the mineral resource and ore reserve inventory has been completed and concludes that Goulamina’s reserves and resources may be enhanced, to the benefit of project NPV, with limited, targeted further work. Amani Gold is looking to acquire more gold tenements in the DRC. Amani Gold has signed a Memorandum of Understanding (MoU) for the potential acquisition of a highly prospective package of 10 gold tenements in the DRC. The package, collectively known as the Gada gold project, is about 80km west of Amani’s Giro project. The company signed the MoU with Bon Génie N. Mining (BN Mining) to acquire 10 exploration permits in the DRC through an 85.7% interest in BN Mining. BN Mining has an option agreement with La Société Minière De Kilo-Moto (Sokimo) over these permits, which are located in north- east DRC within the Niangara, Dungu and Rungu Territories of the Haut Uele Province. According to Grant Thomas, technical director of Amani Gold, the Gada gold project could become a great addition to Amani Gold. “We know the geology, mineralisation and have proven at Giro, that we know how to explore and discover gold deposits in this part of the DRC. The acquisition of this package would see Amani as one of the major gold tenement holders in DRC in a proven gold producing region nearby to the 600 000 ounces (oz) per annum gold mine at Kibali. “We have our teams ready to start sampling and mapping at Gada. The year ahead will see Amani primarily drill deeper at Kebigada, and then complete follow-up exploration drill testing of several of the best prospects defined at Gada,” says Thomas. Exploration in the DRC is not new to Amani Gold. The company has done explora- tion on the Giro deposit in the country before. 6 AFRICAN MINING JULY - AUGUST 2019 This work has commenced and will include further drilling expected to commence in the current quarter, with completion within the September quarter. Any change to mineral resources and ore reserves will also be dependent on the completion of the current metallurgical test work programme and subsequent possible revision to metallurgical recovery estimates. An internal review of the test work undertaken for the Pre- Feasibility Study (PFS) and post PFS has been completed, with a revised test work programme aimed at increasing recovery already having commenced. The first stage of this is High Pressure Grinding Rolls (HPGR) test work, followed by reflux classification and flotation programmes. All impacts resulting from the potential use of an HPGR will be assessed, with the target of ensuring an optimised process flowsheet and metallurgical recovery estimate. A detailed survey of all available road routes for concentrate export between the Goulamina mine site and the Mali ports of San Pedro and Abidjan has been completed, concluding that the available road routes to both Abidjan and San Pedro (bulk material ports in Ivory Coast) are suitable for the transport needs of the project. In addition, an alternative route to port has been identified that may offer a further improvement in current transport operational cost estimates. The report into the water supply options for the project has also been received. The report concludes that the use of surface water dams for water supply to the project is viable and likely to be the most cost effective and secure option. Further work on design and approvals to establish the dams as another source of water have been commissioned. “In the past six months, Birimian has successfully progressed the project’s economics, obtained environmental permissions and lodged the mining permit, strengthened the management and operations teams and continually engaged with our potential offtake and funding partners. “We should complete the optimisation of the current feasibility study for Goulamina in the third quarter of this year and look forward to further enhancements to the project’s economics through that process,” says Evans. www.africanmining.co.za
