The PA mine plan and economic model for the base case includes a Life of Mine (LOM) mine production schedule of million tonnes of mill feed that averages % copper, g/t gold, g/t silver and 0,0058% molybdenum, million tonnes of waste and an average strip ratio of over an year mine

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().

Understanding Mine to Mill is presented in five parts. Part A Setting the Scene provides some definitions of Mine to Mill (M2M) and the historical background. A chronology of Mine to Mill developments is followed by brief descriptions of the very wide range of Mine to Mill applications which have been implemented over the last 15 years.
Over the past 15 years, minetomill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding. One of the most valuable aspects of blasting is the generation of very fine particles (, smaller than 12mm)
The Vulture Company built a 40 stamp mill, and the mine operated profitably from 1867 to 1872. They gave Orrin the goead and they had their own 40 stamp mill up
The F2 factor usually relates received at mill (measured by the mill) tonnages, grades and metal content to delivered to mill production tonnages, grade and metal content. The F3 factor is F1#215;F2 and enables a comparison of a mines (measured by mine) ability to recover the tonnage, grade and metal content estimated in ore reserves.

The Rolling Mill Mine was a drift portal coal mine in operation in Johnstown, Cambria County, Pennsylvania, operating from approximately 1856 until was originally owned by the Cambria Iron Company and was developed in the Westmont hillside across the Conemaugh River from the company''s rolling mill. Its portal was near the confluence of the Stonycreek River and Little Conemaugh River.
Mine to Mill is a site activity and each operation must determine which of the many Mine to Mill variants fits its needs and has the greatest potential to deliver benefits. The old adage that simple is best is true with Mine to Mill, meaning that a strategy does not have to be unreasonably complex to deliver significant benefits.
