Graphic Online BY: Daily Graphic 705 The Ghana Mineworkers’ Union (GMWU) has called for a full scale tripartite investigation involving the government, Ghana Chamber of Mines and the GMWU into frequent mine accidents. This is to correct any possible lapses, and also ensure a more sustainable panacea for development. At the same time, it has also urged the Ministry of Lands and Natural Resources and the Minerals Commission, and its Inspectorate Division to conduct a thorough investigation into the recent underground accident that saw three mineworkers working in the same area trapped. Two of them managed to escape, with one still missing since Tuesday, May 18, 2021.
