A reoptimised openpit design at ASX-listed Manas Resources’ Shambesai gold project, in the Kyrgyz Republic, has reduced the estimated life-of-mine capital costs from $48-million to $38-million. The company noted that the revised design for a smaller main pit, in its latest bankable feasibility study (BFS), used a $1 100/oz gold price pit shell instead of $1 500/oz.
