Summary: In this period of improved metal prices and reported profits, valuable lessons should be recalled from the 1970s when a similar cycle lured the federal and provincial governments into thinking that they could grab bigger pieces of the pie without harming the minerals industry. It took years for the industry to recover from the damage inflicted by that unprecedented scramble for higher tax revenues. It is hoped that the current policy makers will have learned from the lessons of the seventies,...

Summary: Wollastonite (CaSiO3) is experiencing increased usage in a variety of applications, such as fillers in paints, plastics and resins, as an extender to replace both non-fibrous and fibrous materials (e.g. asbestos), and in the glass and ceramics industries. Significant new deposits of wollastonite have been discovered in Marmora Township, about 175 km northeast of Toronto. The geological setting of these large-tonnage, high-grade deposits has recently been investigated to assess the possibility...

Summary: In recent years, there has been rapid growth in the use of natural stone building and construction products. The largest growing markets are for pre-fabricated natural stone panels for interior and exterior wall facing and flooring. This increased demand is attributed to advanced quarrying and processing technologies, renewed appreciation for the aesthetic appeal of natural stone, and to the superior durability of natural stone when compared to glass, steel, and concrete. Geologically,...

Summary: Three varieties of till are recognized in the Beardmore-Geraldton area: local lodgement till, nonlocal carbonate till, and local supraglacial till. The local lodgement till unit is examined in detail for the first time in this paper. It is the best potential overburden exploration medium for gold and other metals because its particles were locally-derived and deposited sub-glacially, probably within a few kilometres downglacier (south-westward) from their sources, and have not been diluted by...

Summary: Time domain spectral Induced Polarization (IP) data from the Tower, Jojay and Laurel Lake gold deposits in northern Saskatchewan are presented. The resistivity data shows both resistivity lows (due to fault, shear or alteration zones) and resistivity highs (due to silicification) in the area of the deposits. The high resistivity zones suppress and distort coincident IP responses, calling for high quality surveys and special care in interpreting the IP data.
Electromagnetic methods are not...

Summary: The metamorphosed mineralized Archean Bourlamaque batholith, dated at 2710 +5-4 Ma, is a homogeneous body, composed mainly of quartz diorite; it is cut by late dioritic, mafic and aplitic dykes, and contains metasomatized ultramaflc xenoliths. A geochemical investigation confirms the calc-alkaline affinity of the batholith, and the REE profiles are similar (La/Yb = 3.9 to 8.1) to those of the intermediate to felsic metavolcanic rocks at Val d'Or into which the batholith was intruded and to...
