Long and Singer further studied Taylor's rule in 2001 and calibrated it to 45 open pit copper mines. The open pit copper model proved to have a curve halfway between the 1998 goldsilver curve and Taylor's Rule. This is due to base metal mines having less aggressive production rates than precious metal mines.
