The holdings of Unicorn Mining Company, Limited, consist of the
Unicorn group of claims adjoining and lying east of the northern claims
of the Big Missouri group.

The claims are underlain mainly by tuffs and other types of volcanic
rocks near the top of the volcanic series. Overlying sediments occur a
short distance east. Most of the bedded rocks are nearly horizontal.
Feldspar porphyry extending northward from the Big Missouri group out-
crops over part of the western half of the Good Hope claim. Most of
the showings are on the Good Hope claim directly north of the Union
and Laura claims of the Big Missouri group. The line of strike of the
deposit found in the Province tunnel of the Big Missouri group passes
well to the west of the Good Hope claim.

At the eastern boundary of the Good Hope claim are two easterly
striking veins and two that strike northwest. The two northwesterly
striking veins are of quartz containing pyrite, sphalerite, and galena.
They are about 3 feet wide and have been traced for 100 and 250 feet
respectively. Samples assay up to 0-2 ounce in gold and 30 ounces in
silver a ton. On the western half of the Good Hope claim there are four
easterly striking deposits and two striking north to northwest. Most of
these deposits are veins 3 feet or less wide, and consist of quartz with
pyrite, sphalerite, and galena. The values approximate 0-2 ounce in gold
and 10 ounces in silver a ton, but occasional high gold assays have been
obtained. One of the easterly striking bodies is a shear zone up to 50
feet wide, sparsely mineralized and carrying low values in silver and gold.
There are three adits 200 feet, 380 feet, and 590 feet long respectively.

The holdings of the Woodbine Gold Mining Company, Limited, con-
sist of the Woodbine and other claims adjoining and lying south of the
Premier Extension Gold Mining Company’s holdings. The property is west
of Cascade creek half a mile from the International Boundary line.

The country rock consists of quartz and feldspar porphyry in general
similar to the fresher and less sheared phases of the Premier porphyry
but containing more quartz. There is some volcanic rock which may
occur as inclusions in the porphyry. The whole is cut by several large
granite dykes striking northwest.

Deposits on the property have been explored by two adits, a number
of diamond drill holes, and surface cuts. The upper adit at an elevation
of 1,260 feet does not disclose ore. The lower adit at an elevation of
1,000 feet is about 3,000 feet long, including drifts and crosscuts. This
adit discloses a large area, 900 feet long in a northeasterly direction and
