FIRST MINING
GOLD
S Duparquet open pit resource shows a potential higher grade opportunity with an Indicated resource of 1.5 Moz at 2.1 g/t Au, at a cut-off of 0.7 g/t (see Table 2)
Mineralized zones are open along strike and at depth, with majority of historical drilling less than 500 m from surface; high-grade mineralized Abitibi structures
prominent at 1,000 m depth
