From a geological perspective, almost all of the commercial vermiculite mines operating today work in deposits which were formed in pre-Cambrian and Archean deposits (1.5-3.0 billion years old). These are quite different from the former Libby, Montana deposit which was Triassic in age (225 million years old).

Recently there has been a lot of confusion about vermiculite and asbestos. Recent newspaper articles, a 20/20 show, National Public Radio, McCall's magazine, and Newsweek, for instance, have addressed problems at the former Libby, Montana mine which has been closed since 1990. These problems were very real, and continue to be a great concern to everyone affected---especially to the many miners and their families who worked in Libby.

Current manufacturers of vermiculite have known about this problem for years, and have had their material checked for possible asbestos contamination.

At The Schundler Company in New Jersey, for instance, during an inspection in early 2000, the federal Environmental Protection Agency tested vermiculite samples from 12 random piles of South African vermiculite, and could not find any asbestos in any of the samples. Also during 2000, testing at the Dillon, Montana mine by MSHA found no asbestos fibers. The results of other testing will be posted as soon as the final reports are completed, but so far initial reports from the other operating mines in North America are looking very, very good!
