We now have in place the operational, regional and corporate experience and expertise to rapidly expand our service lines across a broad geographic area, and to bring our turn-key support services to clients operating within the booming East African exploration and development industries, under our new branding of "Atlas Development & Support Services".
"A key element to our ongoing success will be our ability to maintain an East African identity.
