BI-MEDALLIST, HAWKEYE G ROUP LOCATION

This property i s siutated in the San Juan region, Ouray County, Colorado, about seven miles from Ouray in a southwesterly direction on the southeast slope of Mt. Potosi. I t l i e s i n the vi cin it y of the Camp B ird, Revenue^Virginius and other great producers: d ist a nt from

the f i r s t named about two miles and from the Revenue tunner] perhpas a mile.

ACCESS

Ouray i s the terminal point on a stub of the Denver and Rio Grande Railroad and the property i s reached from t his point by wagon road and t r a i l .

AREA, ETC.

The property con sis ts of two patented claims covering nearly two thousand f e e t of the outcrop, - the B i-m etallist, a f ractio n

four hundred and seventy (470) f e et in length and the Hawkeye, f if te e n hundred f ee t (1500) in length adjoining the Bimettalist on the

south west end, both claims having a width of three hundred f eet (300) GEOLOGICAL FE ATURES

The formation traversed by the Bimetallist vein i s indentlcal with that throughout the greater part of the San Juan region and i s known a s the San Juan andesite, a flow-breccia having a thickness of more than two thousand f e et in some par ts of the d i s t r i c t and proven productive through t his great depth i n a number of the large producers notable; the Camp B ird, Revenue, Tomboy, Smuggler Union,etc.

The Bimetall ist vein i s a well defined zone of fussuring, having a width of twenty fe e t in Places, the chief vein f i l l i n g being quartz

with kaolinite resul ting from alt er at ion of the country rock, accom­

panied by varying amounts of pr yite , some si l ver sulphides, native sil v er and free gold.

The vein has a northeasterly course and dips about 75° westerly a s shown by the workings on the Hawkeye, and i s probably the extension i n a northerly di rectio n of the Wheel of Fortune vein, one of the

e a r lie s producers in t his section: considerable ore having been

freighted from t h i s property to Del Norte - a wagon-haul of nearly

one hundred and f i f t y miles - before the advent of a r ailro ad , the

values in the Wheel of Fortune carrying a lower proportion of gold to

s il ve r than i s shown i n the Bimetallist or es .

DEVELOPMENT

The workings on th is property are shown on the accompanying sketch—map and. cons ist of a shaft and several d r i f t s and tunnels aggregating about 1100 f e e t .

From the sha ft , which was sunk about 40 fe e t from the southwest end line of the Bimetallist claim, to a depth of 150 f e et , two levels have been run; one a t 60 f e e t , marked d r i f t "B", extended 200 fe e t in a northerly run 40 fe e t in a southerly di rectio n and connected with

the surface by a short cros scut. On the second or 100 foot level, d r i f t s marked "C" were run 100 fe e t northerly and 30 f ee t southerly from the sh a ft. No stoping has been done above t hi s l e ve l .

This i s a continuation of the discovery work under which t hi s claim was locat ed, and was sunk on ore which was taken out a s shown by the stoped area on the sketch map; ore of a good milling grade, however, continued to the bottom of the sha ft , the main ore-shoot having a rake to the north and passing out of the sha ft a t a depth of about 60 f e e t .

Development on the Hawkeye claim consists of two tunnels on the vein, shown on the map a s tunnel "E" and Drift "D". The former was an extension of the discovery work on this claim according to the

terms of the bond and lease under which the claim was acquired by the present owners.

Dri ft "D" was run fo r the purpose of opening the vein a t a

deeper level and in a more economical way than by working through the shaft which had developed a considerable flow of water a t the bottom and required the i nst a ll a tio n of a ho ist and pumping plant if sinking was to continue. This d r i f t i s about 600 fe e t in length, beginning at a point 1200 feet southwest of the shaft at a depth of about 375 f e et below the co lla r of the shaft and extending towards i t with the

intention of continuing to a point below the shaft and raisin g to the l a t t e r a s the b est means of developing, off er ing the advantages of drainage, ventilation and economy in operations, besides prospecting the vein a t t his depth.

ORE EXPOSED, SHIPMENTS, ETC.

The ore streak as opened by drift "D" is practically continuous throughout i t s length, having an average width of twelve to f if te en inches and average value about f if t een dol l a rs per ton; assays ranging from four o r f ive dol lars to ten ounces in gold and up to several

hundred ounces of sil v e r per ton.

An examination of the property by an engineer f or east ern p art ie s gave a s a r es ul t of his sampling, taken i n twenty-five foot sections and consisting of f i f t y to two hundred pounds each, an average width of ore for th is d r i f t of fourteen inches and average value of seven­

teen d ol lar s per ton.

Tunnel "E" was not driven on the ore-streak a l l the way, but where broken into i t shows a width of ten to twelve inches of about f i f t ee n d ol lar ore .

From the B imeta llist s haf t ore was shipped carrying nearly one

hundred ounces gold and one thousand ounces s ilv er per ton. The general ra t io of one ounce gold to ten of si lv e r holds f a i r l y well through­

out the property .

which time ore having a gross value of about six ty thousand ($60,000.00) do llar s was exuracted a t an expense fo r mining, f r eight and treatment

° .ahout twenty-two thousand (#22,000.00) d o lla r s . This ore was mainly taken from the stope above the sixty foo t level and was in part very high grade. A copy of statement showing the tonnage and value of shipments made from the property i s attached and may be

verified if so des ired.

In addition to these shipments a mill-run was made a t Ourav

on a fift een-t on l o t from D rift "C", the returns from which were about t hirt y doll ars per ton.

The only ore taken from d r i f t "D" was a mill-run of thir ty-f ive tons which cam from the f i r s t 150 fe e t of the tunnel. Returns from t his l o t gave f if t ee n d ol l ar s per ton in gold and several ounces si l ve r .

Lo attempt i s made here to estimate the amount of ore in the

property on account of the nature and limited extent of the work done, out in consideration of the size and persistence of the ^si n, the con-

inuit y of the ore-streaks and the remarkable grade of some of the ore shipped, the proposition should certainly be an a t t r a ct iv e one fo r more extensive development with every probability of a productive futur e.
