I'm seeking historical information regarding the Marble Mountain (Fulmer) hematite mine near Phillipsburg, NJ. I'm especially interested in any mine descriptions/reports/maps dating from the period in which the site was operational, roughly 1860-1890.

I'm already familiar with the articles by Bayley and the various reports of the NJ State Geologist. This is related to my geological interest in the Neoproterozoic "Chestnut Hill Formation" that hosts the ore.

Thanks in advance!
