American Video Teleconferencing Corp. (PINK: AVOT) is pleased to announce that Wayne Lockhart, BSc. Geology, has joined the company as special geological advisor to AVOT for advancing the company’s exploration programs on its newly acquired rare earth property in Quebec.

Mr. Lockhart has over 35 years experience in the mining business having worked for Falconbridge and Phelps Dodge in eastern Canada, Anglo American Corp.(DeBeers) in Africa and Benguet Cons. in the Philippines. Mr. Lockhart in addition to being a lecturer at the University of New Brunswick in Geology, has developed programs for the United Nations (UNDP). Mr. Lockhart is an Honorary Director of the Prospector and Developers Association of Canada (PDAC), a founding and former member of the Association of Exploration Geochemists and a Member of the Society of Economic Geologists.

China has started to severely restrict the exports of rare-earth materials, which often find use in “green” technology designs, including hybrid vehicles and energy-efficient lighting, as well as in the medical, defense, and consumer markets. The country delivers nearly 100% of the world’s rare-earth materials: 17 metals that are somewhat hard to refine and that tend to occur in the same ore deposits. The cutbacks have resulted in shock waves through the electronics industry and could force design changes in the near future.

Constraints on Chinese exports are creating opportunities for non-Chinese projects.

American Video will aggressively continue to search world-wide for opportunities in Precious, Base and Rare Earths metal projects.
