Portland Ore-Shoot Description
The Portland main ore-shoot was caused by a junction of three veins, one having a N. W. course, the second a N. E, course, the third, a small cross-vein ; size of ore-shoot is from 12 to 30 feet wide, pinching to 6 feet; its length is 175 to 225 feet. Until a depth of 400 feet the shoot pitched S. W., at angle of 52° near surface. At 400 feet in the granite the shoot straightened, and at 600 feet dipped north 85°. There are values in the vein from the Black Diamond to the Anna Lee, a distance of 800 feet.

Portland Christmas Gift
PLEASANTLY REMEMBERED.—The miners employed on the Portland properties each received as a Christmas gift from the management a five-dollar gold piece. As there are about 400 men employed the sum distributed reached an aggregate of $2,000. The friendly feelings that have ever existed between the Portland and its employees will tend to become more firmly cemented by this graceful act tendered as a mark of appreciation of their faithful services.

This came as a pleasant surprise to the stockholders, who had anticipated nothing more than the regular dividend.

Portland Mines Around 200 Tons Daily
Colorado Springs, Aug. 25. The Portland mine is now mining in the neighborhood of 200 tons of ore per day, and the property never looked better for a continuous production. Lately considerable attention has been given to the timbering of the property, so naturally the production of ore has been lower.
graphic for visual presentation of text From reliable sources it is learned that the company intends to erect a large ore house adjoining the already large one built at the No. 2 shaft, so when completed the production from this property will be greatly increased. The grade of ore now being mined is giving average returns of $30 to the ton. and with the immense ore bodies in this territory the production can be made to almost any size.

Portland Mine in 1904 Banner Month
Colorado Springs, Dec. 26.—From reliable sources it is learned that December will be the banner month of the year as far as tonnage and value is concerned of the great Portland Mine on Battle Mountain.
graphic for visual presentation of text
graphic for visual presentation of text Not only is this company sending out its usual quota, between 8000 and 9000 tons of $30 ore, which goes to their own mill, but they will send from 6000 to 8000 tons to the smelters, which should average around $60 to the ton.
graphic for visual presentation of text In addition to this it is estimated that the different lessees operating the large dump from this property will produce more than 3000 tons of ore, which should average $15 to the ton, and, taking the facts in consideration, besides the usual December output, when every one tries to increase the tonnage to the utmost capacity, it is safe to predict that the output for the month will be very close to the two and a quarter million mark.

Portland Mine Stuff in 1908
It must be admitted that the Portland mine now stands as the Independence did some four years ago, when the consulting engineers to that company advised the London office to introduce the leasing system—that is, the Portland is very much of a shell.
graphic for visual presentation of text Its main orebodies, like those of the Independence, are worked out, the average grade of the ore cannot be much more than $16 per ton, and, although the Portland company has its own mill at Colorado City, the profits must necessarily be small, owing to the great amount of waste, large expense of timbering, long tramming distances, and the very low grade of the ore. One must not, however, lose sight of the fact that in this mine the line of contact with the granite, pitching as it does from the Independence north end into the Portland, will give pay-ore at a much greater depth than in the Independence.
graphic for visual presentation of text The Portland may continue to do fairly well a little deeper than this, although, as before stated, the ore seems, on Battle Mtn., to become poorer in depth. The company undoubtedly has a valuable asset in the dumps; these cannot be less than 1,500,000 tons, and remembering the fact that the Portland company, for years, never leased or washed the dumps, the average value of the whole should not be less than $4 per ton. This is a considerable item.
graphic for visual presentation of text It is known that the company has been experimenting on the dump ore for some time at Colorado City, and is now
graphic for visual presentation of texterecting a small plant (10-stamp mill) near the mine. They are proceeding carefully, spending probably not more than $15,000 on the outfit.
graphic for visual presentation of text The method will be to convey the ore automatically to the mill for crushing, pass it over concentrating tables, and then
graphic for visual presentation of textcyanide. The tailing will be put over a second table. It is reported that they are going to very little expense in the matter and are obtaining the most up-to-date tables; by reason of many years of experience in milling their oxidized ores at Colorado City they should be able to devise the best and cheapest means for treating the dumps.
