The talc deposits are consistently associated with a carbonate horizon of the Crystal Spring Formation where it was intruded by regionally persistent gabbro sills. This sill-carbonate rock contact zone contains talc-tremolite rock, which has been mined from 1910 to present. Talc mining ended in 1988 in the mining claims that are now within DVNP.
