Transformational Acquisition, Consistent with our Strategy "Stronger for Longer" • Substantial, low cost production from an established mining  jurisdiction Diversify production base • CY19 forecast production of 92 – 98 koz at an AISC of C$695 – 755/oz (A$740 – 803/oz) 1,2 , with pathway to 200+ koz production • Moose River has meaningful reserves with mine life of 12 years 2  Sustainable long life • High cash margins driven by an industry low all-in sustaining cost operations (AISC) position • Significant growth potential through planned reserve / resource  expansion (Phase 3) and regional drilling (Phase 4) programs Quality growth pipeline • Establishes a platform for future growth in North America • St Barbara is intending to retain the existing operating team and  Talented people seeking to retain key Atlantic executives for the transitional period who deliver • Atlantic's operational team has a track record of project delivery  • St Barbara and Atlantic are trusted operators in their jurisdictions Trusted to operate • Respective operational teams will be able to leverage each other's capabilities and specialisations Reproduced from ASX announcement 15 May 2019 ‘ Presentation on acquisition of Atlantic Gold Corporation and Equity Raising ’ (refer full notices and disclaimer in that presentation) 1.

Perceptions of Young Australians “Just lack of exposure. I mean we are in a big city, there are a couple mines near here, but they aren't very active and the big mines are all in rural areas like WA or South Australia, so I mean it's a lack of exposure, so we might not be able to get an accurate image of like what the job actually is.” - Year 12 Student, Melbourne Source: Minerals Council of Australia
