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.

The presence of laterite described as high-silica bauxite at Mt. Roe on Cobourg Peninsula had been reported early in this century by H.Y.L. Brown, who submitted a specimen for analysis. In the absence of information about the mineralogical composition of the rock the chemical analysis alone affords a very incomplete description of the material. It was considered that the rock might be somewhat similar to the commercially valuable high-silica bauxite which occurs in the Netherlands East Indies and Malaya. At the request of the Australian Aluminium Production Commission the writer was instructed to examine the area in the vicinity of Mounts Roe and Bedwell, and to sample and report on any accessible bodies of apparently aluminous laterite. The locality, topography, and general geology of the area are briefly described. Accounts of the laterite occurrence at Mounts Roe, Bedwell, Kura, and Victoria are given. The mineralogical character of the laterite is described.

The presence of apatite on the southern portion of Alcoota Station has been known for several years. The locality was visited during October, 1944. Two days were spent in the examination of the deposit and mapping. An account of the locality, geology and mineralisation is provided in this report.

There are many modern and ancient opinions on the origin of dolomite, and the general opinion on the geological and geochemical side is that the origin of the dolomites is not yet clear enough. That there are different sorts of dolomites is generally agreed. [Five different kinds of dolomite are defined and described. The possible origins and formation of dolomite are discussed.]

In the Northern Territory laterites are formed in situ as: (i) an illuvial soil horizon; and (ii) a chemical lake laterite deposit. The end product of extensive weathering processes of certain favourable beds is considered by some to be a true mature laterite, whereas others believe it is merely a duricrust. The denudation of laterite and transportation, deposition and cementation of the fragments with other rock fragments result in a detrital laterite deposit. Water-rounded rock fragments in the detrital laterites are readily coated and cemented with iron oxides and resemble the pisolites in the ferruginous zone of the lateritic profile. This similarity results in an exaggeration of the true extent of laterization. The similarity in environmental conditions between the process of precipitation of uranium minerals and laterization is discussed. True mature and detrital laterites are illustrated by photographs.

The collection supports the compilation of national mineral resource and production statistics, and mineral prospectivity analysis. The collection includes the OZMIN database (Australian mineral deposit descriptions including geological, resource and production data); the MINLOC database (mineral occurrence locations sourced from Geoscience Australia and state and territory geological surveys); supporting GIS datasets (eg,mineral prospectivity datasets, ports, power stations); maps and reports.

The rare-earth elements (REE) are a group of seventeen speciality metals that have unique and diverse chemical, magnetic, and luminescent properties that make them strategically important in a number of high-technology industries. Consequently, the REE are increasingly becoming more attractive commodity targets for the mineral industry. This paper presents a comprehensive review of the distribution, geological characteristics and resources of Australia's major REE deposits. REE in Australia are associated with igneous, sedimentary, and metamorphic rocks in a wide range of geological environments. Elevated concentrations of these elements have been documented in various heavy-mineral sand deposits (beach, dune, marine tidal, and channel), carbonatite intrusions, (per)alkaline igneous rocks, iron-oxide breccia complexes, calc-silicate rocks (skarns), fluorapatite veins, pegmatites, phosphorites, fluviatile sandstones, unconformity-related uranium deposits, and lignites. The distribution and concentration of REE in these deposits are influenced by various rock-forming processes including enrichment in magmatic or hydrothermal fluids, separation into mineral species and precipitation, and subsequent redistribution and concentration through weathering and other surface processes. The lanthanide series of REE (lanthanum to lutetium) and yttrium, show a close genetic and spatial association with alkaline felsic igneous rocks, however, scandium in laterite profiles has a closer affinity with ultramafic/mafic igneous rocks.

The Exploring for the Future program is an initiative by the Australian Government dedicated to boosting investment in resource exploration in Australia. As part of the Exploring for the Future program, this study aims to improve our understanding of the petroleum resource potential of northern Australia. This data release presents new field emission scanning electron microscopy (FE-SEM) of broad ion beam- polished samples (BIB-SEM) to visualise mineral and organic matter (OM) porosity on 15 Proterozoic aged shales. Samples were selected from the Velkerri and Barney Creek formations in the McArthur Basin and the Mullera Formation, Riversleigh Siltstone, Lawn Hill and Termite Range formations in the South Nicholson region. Qualitative maceral analysis of the 15 samples are described in addition to bitumen reflectance measurements. These samples were analysed at the Montanuniversität Leoben, Austria in June 2020. The results of this study can be used to improve our understanding of porosity, microstructures, seal capacity and hydrocarbon prospectivity of Proterozoic aged sedimentary basins in northern Australia.
