STATEMENT.


THE Devon Mines embrace the south-west quarter of Section No. 25, and north-west quarter of
Section No. 36, Township 50, north Range 40
west, lying between the land of the Victoria Company on the east, and the Tremont Company on
the west, containing three hundred and twenty
acres, all of which is mineral land.
The accompanying diagram shows the course of
the Minesota vein, and the amygdaloidal belt, each,
to be in length a little over half a mile, across
the property. The diagram is drawn from a map
made by the late S. H. Broughton, Esq., recently
published in Philadelphia. This map is on a large
scale, representing the various geological formations of the Ontonagon District in their true positions, and is accepted by mining men as authority.
Mr. Broughton devoted several years to the search
for the Minesota vein, on the west side of the
valley of the Ontonagon, and in pursuit of this





6


object, he obtained the information from which has
been derived this map, and an excellent Report
which accompanies it.  These publications are
recommended to all those desiring information
respecting the mineral district of Ontonagon.
In a special Report to the President of the Victoria Mining Company, dated September 28th,
1859, Mr. Broughton says, in reference to the Minesota Vein:
" I could have opened it on the Devon, where it
was opened by Mr. Davis on Section No. 25, but
that would not have given sufficient data for the
extension of the line of vein eastward across the
Company's (Victoria) lands in the vicinity of the
River."
Mr. Broughton subsequently commenced an exploration on the land of the Tremont Company,
and that work is now advancing with ample capital for its accomplishment.
THE AMYGDALOIDAL BELT.
Nearly half a mile to the south, and running
parallel to the Minesota vein, is a wide belt of
copper bearing rock, also described by Mr. Broughton. As that gentleman's attention was devoted
mainly to the discovery of the Minesota vein, he
made no examination of this belt, but recent mining





on various portions of it has produced a surprisingly
rich yield, and it promises to rival, in the opinion
of many, even the great Minesota. Its product consists of small masses, barrell work and stamp copper, and the general character of the veins is similar to those of the Portage Lake District. Its
course through the Devon is in a high range of
hills, where the rock out-crops in bold bluffs, offering excellent facilities for mining. Numerous indications of ancient or " Indian diggings " are also
found in various parts of this range.
It is in this belt that the Bohemian, Flint Steel,
and other Companies, have successfully worked
the present season.
South of and near to this range is another range
of hills, where some mining was done about the
years 1847 or 1848, probably the first mining in
modern times on the west side of the Ontonagon
River. The lands were then owned by the Government, and mining operations were conducted under
leases or licenses. The workers on this property
had little or no knowledge of the geology of the
country and apparently mined with no particular
method; there are evidences, however, that they
met with some success, as they cleared about twenty
acres of land, built several timber houses, partly constructed smelting works, and opened a fair wagon

road to the River. These improvements now remain for the benefit of the Devon Mines, and with
the exception of the smelting works, will be found
useful; with these advantages at hand, the Company expect to be able to show quick results from
an exploration on this belt; and as the Tremont
Company are now directing their work to exploring
the Minesota Vein, and both Companies having
the same veins, the developments made by one
Company, will be for the benefit of both.
The Company have to start with -
Two known and valuable Veins.
Improvements to the value of several thousand
dollars.


A fund of Twenty Thousand Dollars.
