Discussion at the Manchester Geological and Mining Society' general meeting held in Manchester, March 14th , 1916, with Leonard R. Fletcher, President, in the Chair, of a paper published in Trans. Instn. Min. Engrs., 1916, vol. L., page 482, comprised the author's written response to suggestions made in previous discussion

A negative correlation exists between sphalerite composition and gold content when gold is transported as Au(HS)2(-); however, there are spatial and temporal differences within a single deposit. A previous model for the formation of volcanogenic massive-sulphide deposits within thermally intensifying and waning hydrothermal sytems in much the same way as is observed around modern sea-floor vents is supported. The results also emphasise that recognition of the mechanisms of gold transport in ancient deposits depends critically on an understanding of their mineralogy and stratigraphy

A computer program has been developed that produces graphic representations of the atomic structure of any crystallographic plane of a mineral. The information provided by the program relates to a purely geometrical model of the crystal structure in which each atom is represented solely by the x, y and z coordinates of its centre. Despite its simplicity, the program can be used as a first approximation model in studies of the interaction between mineral processing reagents and the surfaces of mineral grains which are assumed to be coincident with cleavage planes.

Mining in Argentina is diverse in terms of the number of minerals extracted from the country, but also in terms of the varied approaches and attitudes of mining investors and their trust in the country's individual provinces. Laws are discussed, investment attractiveness and taxation.

Application of the Internet of Things (IoT) technologies - the interconnection of uniquely identifiable embedded computing devices within the existing internet infrastructure - to the mining industry is discussed. IoT technologies are aimed at making projects safer, better optimised and more economic and are applicable to current or new underground or open-pit mines, regardless of size. Two examples are presented of successful implementation of IoT technologies, the Chelopech gold, copper and silver mine in Bulgaria, where production has increased from 500 000 to 2 000 000 tonnes/y and communication costs have been reduced by US $2 500 000 over 2 y, and the Pilbara project in Western Australia, where remotely controlled wirelessly connected autonomous trucks have covered ca. 3 000 000 miles and hauled almost 250 000 000 t of ore since 2008

Offering 1000 hour salt spray protection, the KEYCOAT 1000 coating presents no chipping, cracking or deformation when hammered or flexed through 90 degrees or more. This cost-effective metal protection system features lubrication performance equal to molybdenum disulphide and Poly Tetra Fluoro Ethylene (PTFE) grease providing complete anti-seize protection whilst aiding assembly and disassembly. In addition, the coating is impervious to acids, alkalis, solvents and attack by oils and all fuels. KEYCOAT 1000 has been exhaustively tested in three main industry sectors - automotive, heavy earthinoving vehicles and chemical - where it lias been proven to outperform conventional systems in all respects and as the film formed is less than one thousandth of an inch thick (typically 20 microns), it rarely presents the engineer with any tolerance difficulties. KEYCOAT 1000 is one of a w ide family of products which offer protection and lubrication to a wide industry base, from aerospace to food and with temperatures ranging from minus 190 C to plus 30 C.

The Minister for Roads and Traffic's opening speech highlights some of the topics to be covered in the conference with particular reference to the Channel Tunnel, the recent breakthrough of whose service tunnel marked a historic moment three and a half years after passing of the Channel Tunnel Act and which was the first example in recent years of a major transport project entirely privately funded. The Minister also mentioned the building of UK road tunnels, research and development, and the role of UK consultants in the single European market

The short selection of papers in the special issue provides an insight into the level of exploration activity in Africa and the science and technology that are underpinning it. A country-by-country survey is followed by discussion of geochemical exploration in tropical soils, the Liptako region of Niger, structural styles of deposits in Zimbabwe's Bulawayo-Bubi greenstone belt, structural controls in Zimbabwe's Eldorado shear zone, the regional framework for deposits in the Odzi-Mutare-Manica greenstone belt of Zimbabwe and Mozambique, and the Iperindo deposit in Nigeria's Ilesha schist belt
