Tshipi Manganese price, page-49

It might be worth mentioning that the blog by Alan Patrick Ryan https://intherightvein.com/ , is the founder of Ryan's Notes which gave up to date prices for ferrous and non ferrous metals for nearly 20  years. Patrick Ryan was the leader in this field and producers and other professionals paid thousands $$ to attend his Ferro alloy conferences. Membership for his daily pricing reports also cost thousands$$$pa.
Patrick Ryan  sold his business  in 2012 https://fusiondiginet.com/2012/08/22/cru-group-acquires-ryans-notes/ he is still taking an interest in the ferro alloy markets and hence his blog.
From past experience there is most likely nobody who has more contacts and is more knowledgeable in the industry.
