and by drifts on the vein, at depths of 100, 200, 300, 400 and 700 feet.

This exploration demonstrated that the Monitor vein carries extensive bodies of high grade copper gold ore, and in the course of this development, ore to the value of $73,000.00 was taken out of the mine and shipped to the smelters. Ore bodies were located on every level where drifts were run, from the surface of the ground to the bottom of the shaft. Moreover, the ore found on the lower levels, was copper sulphides, of a character that proved beyond any reasonable doubt that the ore bodies continued downward.

With this fact established, means were sought whereby it would be feasible to open the mine at greater depth. Prior to the building of the Milwaukee Railroad through this district, the only

available tunnel site was located on the opposite side of the range from the railroad. Transportation of ore from this site would have been impracticable.

At this time, the nearest shipping point to the mine was Saltese, a station on the Wallace-Missoula branch of the Northern Pacific Railway. From this station the mine was reached by way of a wagon road six miles in length, which was constructed by the Monitor Company, at a cost of $7,000.00. Owing to excessive snowfalls, this road was impassable more than half of each year, thereby limiting operations to the summer and early fall months.

Work at the mine, during this short period of each year, was carried on as vigorously as conditions would permit.

The Compressor Plant

In the summer of 1910, the Monitor Company's entire plant, including buildings, machinery and equipment, was destroyed by forest fires, and work at the mine ceased.

Mining through the old workings, being no longer practicable, nothing further was done with the Monitor until after the completion of the western extension of the Milwaukee Railroad through Idaho, when the Montana-Idaho Copper Company was organized, and systematic plans laid for the opening of the Monitor at great depth, by a tunnel, to begin at a point near Adair station.

## THE MONITOR VEIN

The Monitor vein is a clearly defined fissure vein, running parallel with the range of the Bitter Root Mountains. Its downward course is nearly perpendicular and its location is central among several well known parallel veins, which have been

developed to some extent, and from which ore has been shipped, showing the same high values in copper and gold as the ore from the Monitor.

Outcroppings recently found on the western extension of the Monitor vein, (through this Company's American and Black Eagle groups of claims) are even better than on the surface at the Monitor shaft.

## TUNNEL TO THE MONITOR VEIN

The tunnel now under construction begins at a point 700 feet north of the railroad sidetrack at Adair. It will run in a northeasterly direction for about 1600 feet, thence almost due east for about 6000 feet.

The first 1600 feet of the tunnel will be a cross cut to the Monitor vein, while the remaining 6000 feet will be a drift on the vein, through the company's own property.
