Another important deposit of crystalline ore is that of Jordan 
mountain about five miles north of Sussex, Kings Co., and on the 
western side of the mountain. The ore bodies occur in a man- 
ganiferous limestone throughout which are scattered, in a manner 
similar to that at Markhamville, more or less extensive deposits 
of p3'rolusite and manganite. Since its discovery in 1882, by 
the present owner, Mr. F. W. Stockton, of Sussex, but little has 
been done, further than a small amount of development work, 
consisting of stripping and an open cut of about eighty feet in 
length, in the bottom of which might be seen an interbedded len- 
ticular mass of ore, principally manganite. From this cutting 
about 400 ton.-> of eighty to eighty-five per cent, ore had been 
extracted. 
Operations have been carrit'd on for many years and by different 
companies atQuaco Head, a bold rocky promontory about one mile 
southwest of the village of St. Martins. Kings Co., unfortu- 
nately, however, with but slight success, owing to the low per- 
centage of ore contained in the rock mass. The deposit con- 
sists of a heavy bed of red calcareous shale highly charged with 
manganite and psilomelane, pyrolusite being of much rarer occur- 
rence than in the limestone deposits of the aforementioned local- 
ities. The property has been worked in a very desultory man- 
ner for man}^ years, energetic operations not having been under- 
taken until its acquisition l\y the present company, who began 
work b}" driving a tunnel into the shales which show a bluff face 
of about 150 feet high. From this tunnel, which was driven about 
sixt}- feet, two cross-cuts were made in either direction for about 
twenty feet. In these workings several small pockets and con- 
siderable quantities of mill-rock were struck and the ore ex- 
tracted, though no shipments were made. In connection with the 
mine a well equipped mill was erected and a wharf built and
