During the production of the Geochemical Atlas of Finland till samples were collected throughout Finland at a density of one sample per 300 km2. The material studied was the fine fraction of till (less than 0.06 mm). The geochemical mapping has shown that elements that are locally enriched in bedrock in the form of ore mineralisation are also enriched in a wide area of the surrounding till. These anomalous enrichments of ore elements take the form of rectangular or curvilinear zones that are some tens of kilometres wide and hundreds of kilometres long. The mineralised zones host ore deposits of different genetic types and can be termed "ore provinces". They stand out prominently on the geochemical maps and can be divided into sub-units of different chemical composition.

"The paper covers the activities of the Government Miners' Training-Schools. It argues that its success is proved by the steady demand for miners trained at the Schools; by the large numbers of ex-apprentices who hold responsible official positions in the industry; and bv the probable expansion of the organization in the near future to meet the never-ending call for trained personnel."

A personal overview and assessment is given of the 42 papers delivered over the three days of the symposium. As well as 18 from the UK there were presentations from 16 other countries; 20 were on rock tunnels, 13 on soft ground and 3 on both; there were 17 case histories and 16 discussions of tunnelling machines but, for the first time in the conference series, almost no papers on tunnelling for mining purposes. Some projects, such as the Lesotho Highlands Water Project and the London Ring Main, attracted a number of papers addressing their different aspects

It is shown that sodium can be removed very readily from molten aluminium by the use of a beta"-alumina, the more highly conducting form of beta-alumina, provided that the surface of the tube is wetted by a layer of salt. From current/time plots the theoretical amount of sodium removed has been calculated and excellent agreement obtained. The beta"-alumina tubes can be immersed directly in the Al without fracturing if they are pre-heated for a few minutes prior to immersion. According to its stability beta"-alumina should be attacked by molten Al at low Na contents, but in these experiments the salt acted as a protective layer. Magnesium chloride is a relatively cheap salt, whose Mg product can be used within a foundry. The only other product is NaCl, which can be used in-house as a flux or sent for disposal. No polluting gases are used or produced and no drosses created. The time for removal of sodium was quite short, comparable to that for chlorination

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.

Strong disagreement is registered by A.A. Rocha Gomes with Leca's account of the discovery published in Trans. IMM B, vol.99, 1990, p.B139-B152, which he contends minimises the role of the Portuguese state organisation Servico de Fomento Mineriro (SFM); the author, in response, once again thanks all SFM staff but reiterates his conclusion that Neves-Corvo was discovered through an amalgamation of exploration results and interpretations from different sub-disciplines and geoscientists
