News release ---------------------------------------------------------------------- North American Tungsten Corporation Ltd - Patent application approved North American Tungsten Corporation Ltd. NTC Shares issued 10,405,975 1998-11-30 close $0.11 Tuesday Dec 1 1998 Mr. Stephen Leahy reports The U.S. Patent Office has allowed the company's patent application. The patent, serial number 08/482,129 entitled Pyrometalurgical process for forming tungsten carbide is held in the company's 100 per cent wholly-owned subsidiary, International Carbitech Industries. Formal issuance of the patent is expected in the near future upon filing fee payment and paper work processing. Patent filing in other worldwide jurisdictions is expected to commence in the near future. The company has spent over three years and close to $1-million on extended research to this patented tungsten process. The original patent owned by the U.S. government was licenced exclusively to ICI in 1995 until the year 2002. The company through its research to commercialize the original patent significantly improved and altered the process methodology thus applying for its own patent which, will now be valid for 17 years.The pyrometalurgical tungsten process substantially reduces the steps required to create tungsten carbide powder and sodium tungstate directly from tungsten concentrate ore. This reduction of processing steps and time will significantly reduce the cost of processing. Tungsten carbide, which is second only to diamonds in hardness, is used in numerous industrial applications, from light bulb filaments to a variety of cutting tools.The current industry method of processing tungsten involves the transformation of the actual concentrate into ammonium para tungstate and then numerous additional procedures creating metallic tungsten and tungsten carbide materials.The company's method is radically different, in that tungsten ore is refined directly into tungsten carbide and/or sodium tungstate, thus eliminating the various intermediate processing steps. This ability to significantly the complex processing procedures currently in use, will greatly affect processing costs allowing for greater flexibility in end use commodity pricing. The advantage in processing costs will allow the company to be competitive in both the processing industry as well as the raw commodity tungsten concentrates. Given that the company also owns substantial tungsten ore reserves, this will allow for the creation of a low cost, fully integrated producing capability that would expected to be competitive on a worldwide scale. Once the patent attains commercialized status the company, will have the ability to not only process its own ore but also will allow for the potential licencing of the processing technology to other worldwide tungsten producers. ----------------------------------------------------------------------
