An iron-phosphate mine located near Hurdtown, about 5 miles North of Dover. Started and closed before 1855. Ore was a pyritiferous magnetite.

Although apatite is very common in the iron ores of northern New Jersey, this is one of the very few ore deposits where it becomes a major component. Unfortunately, this prospect is so old, pre-1855, and so sketchily described that a precise understanding of the nature of the ore may be impossible. Bayley(1910) says that apatite "occurs in irregular seams, often intermixed with pyrrhotite...". This suggests secondary hydrothermal reworking, possibly during the long period of pegmatite intrusion and hydrothermal activity that followed the Ottawan orogeny. Unfortunately, this is anything but clear. Elsewhere, Bayley notes that the apatite is "usually in aggregates mixed with all the other minerals mentioned". This sounds more like the dispersed occurrence common throughout the region.

It seems that the ore was to low grade and sulphidic to be mined for iron and to low grade to be mined for phosphate.
