The mineral resources and mining industry of the Mandated Territory of New Guinea are the subject of this report. Mining operations, production, and geological conditions are discussed. Tables showing the estimated gold and silver production figures for the period 1926-41 are appended.

Mineral deposits in Papua include those of gold, copper and manganese and from these there has been produced gold; silver; copper, copper matte and copper ore; manganese ore; osmiridium and platinum. The gold has been obtained from alluvial deposits and lodes and from the copper deposits. Silver has been obtained along with the gold, but no separate record of it has been kept. The copper and manganese ores have been obtained from their respective deposits. The osmiridium and platinum have been won during the mining of the alluvial gold deposits. A fairly intensive search has been made for petroleum, but there has not been any commercial production. The total value of the mineral production to 30th June, 1941, is £3, 246, 353, the detailed production being as follows: [see table in record].

This report gives a brief overview of the situation and geological features of the barite deposit.

A mineralight examination of scheelite occurrence at Hatches Creek and Wauchope was carried out. The results of the examination are recorded in this report.

Within three miles of Broken Hill railway station are numerous pegmatite dykes carrying a high proportion of massive felspar. A few of these dykes are worked sporadically by gougers. On June 8th and 9th several of the dykes which were being, or had been worked were examined in company with Mr. B. Hadley, Inspector of Mines. A description of the individual deposits and a discussion of production capabilities are presented in this report.

An examination was made of a wolfram vein seven miles north of Broken Hill, on July 8th, 1943. This report contains brief notes on the nature of the vein and the mineral specimens examined.

These deposits, usually known as Hite's Felspar, are situated southeast of Bombala, in M.L.1., Parish of Nalbough, County of Auckland, on the easterly slope of a spur running northward from a sister peak to Wog Mountain. This preliminary note concerns the situation and geology of the felspar and molybdenite deposits at Wog Mountain.

The felspar deposit near Londonderry was examined on Saturday, September 11th, 1943. The deposit has been worked by open cut, the size and shape of which are given in the plan accompanying this report. The report comprises rough notes on mineral assemblage and production figures.

The dykes which contain the felspar outcrop lie on the western slope of a hill two miles east of Wodonga, and south-southeast from Albury. This report comprises notes on the occurrence of the felspar and descriptions of the individual deposits.
