Lunar Resources Utilization for Space Construction. Study conducted for NASA by General Dynamics Convair Division in 1979 concluded that lunar resources could supply 90% of the material for power satellite production and become cost effective if more than 30 satellites are produced. A nice summary of this study appears in Toward Distant Suns, Chapter 8.
