Cut-off grades are essential to determining the economic feasibility and the mine life of a project. Increased cut-off grades can reduce political risks by ensuring higher financial returns over shorter periods of time. Conversely, lower cut-off grades may increase project life with longer economic benefits to shareowners, employees, and local communities. Cut-off grades also impact reported reserves, which are closely monitored by stock exchanges and regulatory agencies.\u003c\/p\u003e\u003cp\u003eJean-Michel Rendu provides practical insights into this critical variable. You’ll learn about minimum cut-off grades, as well as those for deposits containing multiple valuable minerals. Rendu also identifies which costs to include in cut-off grade calculations and considerations when planning open pit, underground, and block and panel caving operations. He explains how to optimize a copper mining project by changing grind size, and demonstrates the relationship between deposit modeling, ore control, and cut-off grades.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e","brand":"Society for Mining, Metallurgy, and Exploration","offers":[{"title":"Default Title","offer_id":47016021688560,"sku":"9780873352680","price":89.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780873352680_p0.jpg?v=1763836080","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780873352680","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
