South African gold producer Aurous, which owns and operates the Blyvoor gold mine and the Gauta tailings retreatment project on Gauteng’s West Rand, has announced plans to go public through a business combination with US-based Rigel Resource Acquisition Corp. The transaction, which puts Aurous at a pre-money equity value of some R6.76-billion ($362-million), is expected to enable Blyvoor to expand its underground infrastructure, enhance surface infrastructure, and optimise operations through economies of scale.
