Canadian junior miner Caldas Gold has completed an updated mineral resource estimate for its Marmato project and also announced the preliminary results of a prefeasibility study (PFS) for the project, in Colombia. The PFS affirms the economic viability of the underground expansion of the Marmato project at a long-term gold price of $1 400/oz, and a total life-of-mine (LoM) undiscounted after-tax free cash flow from mining operations amounting to $770-million.
