Estimation of the potential production rate,

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 gold-silver curve and Taylor's Rule. This is due to base metal mines having less aggressive production rates than precious metal mines.Costmine - Industry Standard for Mining Cost Estimating,I’ve subscribed to Mining Cost Service continuously for more than 12 years which has greatly assisted in the development of my estimating skills as a Mining Consultant.

Open-pit mining - Wikipedia

Open-pit mining, also known as open-cast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an open-air pit, sometimes known as a borrow..
