Morgan, P.G.; Bartrum, J.A. 1915 The geology and mineral resources of the Buller-Mokihinui subdivision, Westport division. Wellington: Government Printer. New Zealand Geological Survey bulletin 17 210 p.

Abstract: This bulletin forms a comprehensive report on the geology and mineral resources of the Buller-Mokihinui subdivision, which includes the whole of the Buller coalfield, as well as less important mining areas. From an economic point of view the Buller-Mokihinui subdivision is noted for its deposits of high-grade bituminous coal, which for many years have been actively mined by the Westport and other coal companies. Brown coal and lignite also occur in quantity. During the past fifty years or so some millions of pounds’ worth of gold have been won from rich surface gravels, but the alluvial-mining industry has now greatly declined, and the present gold production is only a small fraction of that which characterized the palmy days of 1866 or the immediately succeeding years. Among other natural resources of the subdivision are auriferous-quartz lodes, building-stones, cement-materials, brick-clays, and a few minerals of minor importance. A considerable amount of valuable timber still remains in the forests, but this asset is a diminishing quantity which will be almost exhausted before the close of another generation. (auth/DG)
