The geology Of the Gilmore district is
simple, and important by reason ol me ne
fact that IL compares very closely In lls
lstratigraphlc relationship with severai oI
the most important smelling ore districts
in the west. Its rich ore disclosures and
shipments have already attracted the at
tention OF the United States geological
survey, who have had one OF their eX-
perts In the field already for reconnois-
sance purposes and additional work on
this line. / am informed, is TO be taken

deal OF interest by the mining operators
OF the district.

that the main assures cut the bedding of

posLts Of this district invariably carry

be surprising II ore containing bonanza

extensive development Of its deposits.

splendid BODY OF soft brown iron ore six

mine, and raise is now being made upon

A 100 horse power steam boiler and

mine IS By no means the only resource
