Activity Florida NW mine (open pit) Florida NW Mine
At 1355 level, by the end of Q4 there are 265,328 tons of mineralized material with average grades of 2.4 g/t Au and 171 g/t Ag over a width of almost 6m.
NW Florida Mine
An open pit economic evaluation was conducted for this zone up to elevation 1280 which is the bottom of bodies blocked by the development of underground works. The result of the analysis yielded a volume of 332,500 tons of mineralized material with average grades of 1.9 g/t Au and 178 g/t Ag; and 2,720,000 tons of waste material to be removed. This gives an overall stripping ratio (RD) of 8:1 while for the comparative critical RD (Open pit vs Underground) is 10:1 and 53:1 for the RD economic limit, making it economically feasible and due to the structural complexity of the area, the open pit mining is reasonable.
0.65 Km of access roads were completed in Florida Tajo through E flank in order to access the lower banks with 14m3 trucks.
