The following Northern Orion Resources link is about 10 years old but it gives excellent information about the significant operations of the company and being part of Yamana Gold. Also, the link indicates Northern Orion Resources is based out of Toronto which per EW's organizational map of MSJ who purchased the 6 properties of SRGE earlier this year, MSJ also starts out in Canada and works its way down thru Mexico and South America.
