Recent exploration at the newly added Siuna mineral concessions belonging to TSX-V-listed Calibre Mining’s 253 km2 silver-gold project, in north-east Nicaragua, is returning positive results. The company said last week that exploration activities at the Siuna project, which added some additional 241 km2 to the 12 km2 La Luz project, highlighted the historic gold trend of the region, with new results expected to prioritise drill targets moving forward.
