Meanwhile Beadell, which was one of the lowest cost producers for the December quarter, was hurt by falling iron ore prices. As a by-product of gold production iron ore can be credited towards All.
Aug 01, 2018 In contrast, lode-gold deposits account for the majority of production (69 ) whilst only accounting for 37 of reserves and 32 of gold resources at operating mines. Thus, at 2018 rates of production, the average mine life of Australia's lode-gold deposits appears considerably shorter than for other deposit types (Table 2).
