This regional report covers the mineral industries of Canada and 40 countries and areas in Latin America and the Caribbean Basin. Also included is a brief description of the mineral potential of Antarctica. The Latin American region encompasses an area twice that of the United States. Latin America and Canada have a rich and diversified endowment of mineral fuels, metals, and industrial minerals. Tables 2 and 3 provide a summary view of the importance of Latin America and Canada's output of its major mineral commodities in world mineral supply in 1989 and 1990.

This glossary is publi~hed- by the Bureau of Mines as a contribution' to the mining literature in the belief that it will fill a long-felt need. It contains about 20,000 terms; these include both technical and purely local terms related to metal mining, coal mining, quarrying, petroleum, and natural gas, and metallurgical works; names of useful, important, and common minerals and rocks; an<lgeological terms. It presents in one comprehensive volume the available standard, technical terms relating to the mining and mineral industry, as well as provincialisms that have been or are now in use in English-speaking countries. The glossary also includes many terms relating to ceramics and the clay industry, glass making, foundry practice, railway and building construction, electrical installation and power-plant equipment, and chemical terms relating to metallurgical practice. Complete lists of terms for' each of these allied industries are beyond the scope of this glossary. Paleontological terms, although closely associated with geology, are far removed from mining and metallurgical operations, and for this reason have been omitted. In a compilation of this magnitude, it is difficult, within a reasonable time to verify all definitions as to the latest usage. Much verifying was done and it is hoped that the best and latest definitions have been used. Reference to the publications cited will enable the reader to determine approximately the period when the definition was used. Definitions in use by engineers of high national or international reputation are given first preference. When definitions from different sources are the same, credit is given to the earlier author as being the original or nearest to the original source. Immediately following each term the name of the locality wherein the word is presumed to have originated or is widely used is given, where such information is available. The name of the author or source from which the definition was obtained follows the definition, and serves as a key to the publications listed. The terms selected from the various glossaries and publications examined have been compared with the Webster,

This report describes the design and testing of an improved quiet hard rock percussion drill. The improved drill incorporates a tappetless design with independent rotation in a hand held drill weighing 50 lbm. Laboratory and field testing in three mines were conducted. The testing showed improved drilling performance with no increase in measured noise levels over the fist design.
