Dunne August 26, 1999 This diskette contains data on global porphyry and related deposits as implemented in Microsoft Access 7.0 under Windows 95. The data are contained in an Access database file under the name OF3792a.mdb. The documentation is contained in the Microsoft Word for Windows Version 6 file OF3792a.doc. These two files have been placed in the self-extracting PKZIP file, OF3792.exe. The contents of this zip file, once extracted are: OF3792a.mdb 1,634 KB 11/8/99 11:21 AM OF3792a.doc 290 KB 10/29/99 2:21 PM -------------- 1,924 KB Every possible effort has been made to ensure the accuracy of the data provided; however, the Geological Survey of Canada does not assume any liability for errors that may occur. Locations recorded in the database are as approximate as the data sources from which they are derived. A few deposits located on or near national boundaries may be recorded in the database as occurring in one country, but may plot slightly on the wrong side of the border. This may be due to inaccuracies in the base map, diagram, or publication from which their locations were taken, and/or uncertainties in the positioning of the border in the base map we are using to superimpose the data, as well as possible transcription errors. Resource data provided with this database is for ad hoc geological reporting purposes only, and does not in any way reflect resource estimations or evaluations performed at the GSC. Users may wish to verify critical information. The data are provided "as is". The Geological Survey of Canada does not warrant that the data are free of defects or that they will meet your needs or the needs of any other user or that they will be merchantable or fit for any purpose. In no event will Minerals Resources Division or the Geological Survey of Canada be liable for damages including any loss of profits, lost savings or other incidental or consequential damages arising out of your use of or inability to use the data.
