Comments on the site identification

  • 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.

Comments on the location information

  • PLSS Locations are in non-adjacent sections at least 5 miles apart. Should probably be entered as separate records.
  • The Ajax (or Hales) is several townships to the west. Yet the deleted record 10210684 cites Ajax as a data source.
