The National Union of Metalworkers of South Africa (Numsa) officially embarked on strike action on Monday, following a breakdown in negotiations at the end of June, saying it would not budge on its demands for a 13% across-the-board hike, better working conditions and a ban on labour brokers. Numsa, which represents about 120 000 workers, is being joined by five other trade unions, jointly representing at least another 50 000 workers. The strike action comes hard on the heels of growing alarm among South African mines about the impact of increasing talk of nationalization from factions within the ruling party.

News24 reports new hydraulic technology from South Africa's Peterstow Aquapower has the potential to change the way mining is done if widely adopted in the industry. The drill technology uses water as a hydraulic fluid instead of oil but also no external air compression or water as with conventional mining. The drill presents a "plug-and-play" system for mining as it promises to reduce costs and work more effectively. The machines cut the water use by 80% and can save about 28% of electricity costs for a mining operation.
