A mercury mine located 3 miles West of Antoine River, on the North side of Ashbrook Road. Features shafts and underground workings, trenches & cuts. Mineralization is in Jackfork Sandstone. Started 1941 and closed 1944.


Structure: Homoclinal Fold, Nw Trending Strike Slip Faults Thrust Faults, N-S Tear Faults, And Two Fold Systems ; Reg.Trends: Thrust Faults From S In Late Paleozoic

Alteration: Argillic

Deposit: Hg is disseminated in sandstone, and concentrated in fractures.

Development: Most development and most production comes from humphreys g-2 rotary furnace has 100 ton per day capacity.

Geology: Geol.desc: carboniferous formations dip S and are deformed by thrust faults, tear faults, bedding plane faults, and folds

Rock formation(s): Jackfort Sandstone Penn. Sandstone;Stanley Shale Penn. Shale


Ore(s): Ore Located Along Faults In Breccia And Joints. Fault Intersections, Sharp Folds And Intersection Of Sandstone Beds With Main Fault Zone Are Favorable.



A.B. Wilson merged and deleted what appears to be an undocumented and duplicate record for "Humphreys 6-2,6-3,6-4,26-1 Prospect". The only references in newMRDS 10210684 (MAS 0050190010) were the USGS topo, the (non-existant?) ARKANSA MINERAL BOOK: THOENEN (which I have been unable to locate), and a mention of "SEE AJAX MINE, PIKE CO, ARK". It appears that the all the "6-" may be meant to be "G-". This record supposedly plotted in T7S, R21W, Sec. 1, NENESW. It may or may not have been owner or operated or leased by or to International Paper Co., Ark Quicksilver Division as of 1944.
