Adam Zimmerman was involved from the very beginnings of Noranda Mine's foray into the forest industry sector. In April 1961, Zimmerman was part of making the deal to acquire National Forest Products, Noranda's first forest products company, which was renamed Northwood Mills after its purchase. By 1964, he was the President (and later Chairman) of Northwood Mills and Northwood Pulp. In 1974, Zimmerman was appointed Executive Vice-President of Noranda, which included responsibility for the forest products activities of the company. When Noranda underwent a major company reorganization in 1987, Zimmerman became CEO of Noranda Forest Inc. By the end of his Noranda career, Zimmerman had had an executive or director role in nearly every forest product company developed or acquired by Noranda. That included: Northwood Mills, Northwood Pulp (and its successors Northwood Pulp & Timber and Northwood Forest Industries), Noranda Forest Inc., BC Chemicals, BC Forest Products, Bulkley Valley Forest Industries, Fraser Inc., Maclaren, and Macmillan Bloedel, among others. The records in this series demonstrate Adam Zimmerman's extensive involvement in Noranda's forestry division throughout his career.
