Portland Mine Cost of Producing Gold Cripple Creek is distinctly a gold camp, though the ores, with one or two exceptions are very low in value. The cost of producing gold from the Portland, which has put in considerable machinery, is said to be at 30 cents for every $1 worth of gold.

Portland Mine is ImprovingNOT STOPING YET.
—————————
In conversation in Denver Mr. Doyle, of the Portland mine, is reported to have said: ''The camp is better than ever today, and although, the tonnage output has fallen off a little during the past month the new strikes will greatly increase the production as soon as the necessary machinery is in place on the new producers. I don't know that I can give a reason for the falling off in the shipments.
Of course the shutting down of the Annie has had a good deal to do with it, but as you can imagine I have had too much to do in connection with our own property to pay very much attention to what other properties are doing.
The Portland is improving right along and our shipments are made entirely from development work. No stoping has been done in the mine to speak of; in fact, none at all. We have been compelled sometimes to enlarge the drift in order to work to advantage, but I don't call that stoping, even when we have to take out one or two stopes.
There is no immediate prospect of our commencing to stope out for some time to come, though a great many people seem to think so.
When the Portland company commences to stope everybody will know it."

Short Description of the Portland Mine Above the Independence, higher up the steep hill, is the Portland, with its fine new shaft house and remodeled shaft. This singular mine was the scene but a few months ago of a terrible disaster, caused by the caving in of the timbers of the octagon-shaped shaft. This mine is unique. It is located apparently in the throat of a geyser, consequently the shaft descends for some 800 feet like a wide well, surrounded with octagonal or polygonal timbering.
The ore is confined to the almost circular throat of this geyser. Descending the shaft to the bottom, you find yourself on a smooth floor, circular or octagonal in form. You dig into this floor with your pick and turn up a quantity of little dark pebbles of phonolite like so many peas or marbles cemented together by a sandy paste. This is the rich ore body, and like the Bassick at Silver Cliff, the mine must keep to its well walls and go ever downwards as if in a well.

Battle Mountain Water Problems For some time past the water problem in the deeper mines of Battle mountain has been a serious one.
Not many weeks ago the lower levels of the Independence were flooded by a sudden inflow of water, and Mr. Stratton was summoned by wire to give directions as to its handling. It is known that an offer was made to the C.O.D. company for one of their enormous pumps which is lying on the ground, but that company refused to sell the machinery.
The Portland, too, has a heavy water flow to contend with, and the management has evidently taken time by the forelock and will put in such pumps as will not soon have to be replaced.

Portland with Greatest Strike Ever KnownGREATEST GOLD STRIKE EVER KNOWN
—————————
Portland Has Opened the Richest Vein Encountered in the History of Colorado.
—————————
NOTHING LIKE IT EVER SEEN HERE
—————————
A Carload of It Will Be Worth Two Hundred Thousand Dollars.
—————————
SHIPMENTS ARE TO BE MADE THIS WEEK
—————————
The Rich Streak is From One to Three Feet in Width and is Found At a Depth of 950 Feet.
—————————
The Portland is the best gold mine in the state of Colorado. It has been the big proposition of the greatest gold camp on earth for nearly five years now, and is pretty certain to hold first place for years to come. In the past the Independence, Strong and Gold Coin were thought by many to be equal to it, but a discovery made a few weeks back and which is now made public for the first time, will place the Portland so far ahead of its rival that no on will be liable to question its right to be called the king of the camp.
In a crosscut ran east from the 700-foot drift from the Burns shaft, at a point some 300 feet north of the old abandoned working shaft of the Anna Lee, a vein of fabulously rich ore was entered some two weeks ago. Rumors of the big strike have been floating around camp for the past week, but for reasons best known to the management, no information could be obtained in regard to it.
The new ore body was cut on the Hidden Treasure, about 240 feet east of the old Lee vein. A drift has been extended 75 feet on the chute, which has an average width of 4,5 feet. There is very little waste in the vein filling.
Along the hanging wall the high grade streak of sand quartz and hard fluorine stained rock varies in width from one to two feet. This streak was stripped in running the drift and the work of breaking it was commenced a few days ago.
The rock broken in drifting has been shipped and ran from $60 to $100 per ton, with little or no sorting. The sand quartz is very light and porous, and varies in width from ten to twenty inches. Some picked specimens of it appears to be half gold.
An assay on a sample of four pounds which was picked off the full height of the drift from a ten-inch face, showed a value of a little less than $38,000 per ton. No assays have been obtained running less than 400 ounces, or $8,000 per ton on this ore.
The fluorine quartz seam alongside it is not as rich, but assays better than two dollars per pound. It is fairly alive with sylvanite.
A strong and large wooden room, heavily padlocked, has been built in an abandoned drift, and here is where the ore is being stored. A broad-gauge car of each kind will be sent to Denver the latter part of the week. Each car will bring more money than any car of ore ever taken from any gold or silver mine in Colorado.
The sylvanite ore will easily average $4,000 per ton, and the sand quartz fully $8,000. The Portland load their cars on an average with 25 tons. This means $200,000 for one and $100,000 for the other.
The importance of the strike cannot be overestimated. It has doubled the earning capacity of the only Portland. The stock will advance in price and will have a tendency to check the downward movement of other good Cripple Creek mining shares brought about by the war. The strike is still of greater importance, on account of having been made at such a great depth. The breast of the drift is 950 feet below the surface, and several hundred feet beneath the water level.
It proves that with depth ore chutes in the camp improve both in richness and width. The same vein was uncovered on the Captain three years ago. Near the surface the grade was not as high, and the width was only a few inches. The ore now which is being carefully sacked at the 950-foot level, is richer that any ever mined in the camp, and there is plenty—twenty times more of it.

Portland Prepares for Bigger BusinessPORTLAND PREPARES FOR BUSINESS

Shaft Will Now Be Put Down to One Thousand Feet and Levels Run.
—————————
IMMENSE NEW PUMP ORDERED

Preparations are being made on the great Portland mine to go after ore as never before in the history of that rich property. It has long been known as one of the steadiest shippers and rich dividend payers, but recent enormous strike of ore in the lower levels, along with the sustained production from the known ore deposits, has determined the management to vastly increase the output, and hence the money-making capacity of the mine.
Significant among these preparations is the ordering of a bill of 200,000 feet of lumber for an addition to the ore bins, work on which will begin to-day. The present capacity of the bins is 350 tons, and when enlarged as planned they will be three times that figure, or able to hold 1,050 tons.
Another step in the movement has been an increase in the boiler capacity of the mine. Yesterday steam was raised for the first time in two new boilers, each having a capacity of 100 horse power. The boiler capacity of the Portland is now 800-horse power.
In line with this policy, is the ordering of a new pump. It will be a beauty, capable of handling 1,200 gallons a minute, raising that amount of water to a height of 1,000 feet.
Work on the shaft will begin at once and it will be put down to a depth of 1,000 feet. The last level was run at a depth of 800 feet, though the sump is some 75 feet deeper.
Another level will be run at 900, and still another at 1,000 feet.
Already the Portland is famous for the amount and value of its ore production, and when these plans of the management have been carried out it will stand head and shoulders above its present height.

Portland Doing Good at Depth DENVER, COLO, May 2, 1898—During the past week the mining stock market has been much more active than it has been for a long time, and the Portland stocks advanced 7½ cents per share.
The cause of the advance is traceable to the improved condition and the confirmation of increased values in great depth of over 900 feet deep. Miners has just opened up a body of the richest ore yet found in the mine, perhaps, in the whole district—some specimens being described as half gold.

Portland G. M. Co. Decided to Use Steel in Its Main ShaftA Mine Shaft Cased with Steel.
A departure in mining engineering is the decision of the Portland Mining Company, of Cripple Creek, to fit out its main shaft with steel, the supports and sets to be of that material, with timber for lagging, on the ground that a shaft constructed of steel will be stronger, more durable and cheaper than the ordinary timber shafts, with a saving in the time of construction.
The corner posts are to be composed of structural steel 1 inch thick, cast at right angles, with the angles inside, the several lengths solidly bolted together.
The square sets are of the same style of iron, to be firmly bolted to the uprights at intervals of 6 feet. The lagging is to be composed of 4 inch plank, set in endwise, with broken joints, so that the pressure will in no place come against more than 6 feet of plank.
The cost of the steel structure with the heavy lagging is just the same as if the shaft timbering was composed entirely of wood, but the saving is in the rapidity of construction, the greater durability of the steel and the saving in excavation.
A timber shaft requires timbers of from 10 to 12 inches square, while the steel is but 3 inches thick, and, on account of its shape, presenting a sharp edge to the rock, can be readily fitted with a few blows of a pick.
The saving in excavation in a three-compartment shaft, such as that in use at the Portland, amounts to nearly a yard and a half of rock work for every foot of depth gained—an important matter in such a shaft as the Portland, with its 1,000 feet of depth.

Portland Mine Resumed OperationsSTRIKE AT PORTLAND MINE SETTLED AND WORK RESUMED
————————————
Victor, Colo., June 4.—The reopening of the Portland has been the main topic of conversation throughout the district since a telegram from Mayor Franklin of Victor, sent from Colorado Springs at noon yesterday, gave information that terms of a settlement had been agreed upon between the mining company and the Miners Union. This morning the engineers and surface men were put to work, and as soon thereafter as possible the force will be increased to about the same number of men as was worked before the mine was closed down.
The Portland was shipping about 7,000 tons per month when it was closed down, and it can easily continue this output. On June 1st a contract with the American Smelting and Refining Company went into force and the product will go to the smelters until the company's mill, now being built near Colorado City, is completed. After that a large share of the production will be treated by the company.
Since the shut down a force of men has been employed preparing for the new ore bins to be built at shaft No. 2 on a spur of the Short Line railway which is being built from Independence, and as soon as the line is completed, the ores of the company will be shipped over the Short Line road, in which it is a large stockholder.
Reports of the sale of the property are not generally believed in face of a resumption of work at this time. It is known that negotiations for the purchase of the property by English investors were in progress at the opening of the year.
On the other hand it is known that the English investors want more Cripple Creek mines, and the Portland would be their first choice could the present owners be induced to part with it.
The resumption of operations at the mine will have a stimulating effect on the district, and will be beneficial in many ways. The fear of a general strike involving protracted labor struggles is removed and probably will not arise for a long time.
At a meeting of the unions held in Altman Sunday night a proposition was made which was taken to the Portland officials at Colorado Springs yesterday by a committee of business men. The Portland directors held a meeting and the proposition of the miners was accepted without delay. Neither the union nor the Portland people will give out the terms of settlement, but they are said to be the same as those laid down by Mr. Burns and published in several papers Saturday morning.
These are:
No compulsory insurance
the mine to collect union dues
and secretaries of the union to refrain from visiting on union business
and no discrimination against the union in employing miners at the Portland. So far as can be learned, nothing was done in relation to machine men or firemen's wages.
When the news of the settlement reached Victor to-day 500 or 600 former employees of the Portland went to the mine to apply for their old places, but it was given out that no men would be hired until the mine is ready to resume operations, which will be Thursday or Friday of this week.

Ore Handling at Portland Mine in 1902 Mill Practice in Colorado.— The Mining Reporter issue of March 6, 1902 has on page 252 some words in regards to 'Ore Handling at Cripple Creek' where the article mentioning that at the Portland mine, Cripple Creek, the fine portion of the ore is separated by a screen; the coarse portion, which constitutes the bulk of the ore, being hand sorted. Formerly the fine material with a value in gold of about $4 per ton was rejected, but at present a saving of 50% of the contained value is effected by a simple washing process.
The washer consists of an inclined iron plate perforated with holes 0.625 in. in diameter, on the upper surface of which numerous jets of water impinge in various directions.
The waste is passed over a screen which removes the dry fines; the coarser portion, which forms the bulk of the waste, is then passed over the perforated plate, the adhering fines being washed off by the jets of water, and collected and dried on a sheet iron box, heated by exhaust steam.
The small quantity of water used is circulated through a boiler-feed pump operated by exhaust steam. In this way the final waste is reduced in value to an average of about $2 per ton.

Portland Mine Back in Action The mine on Battle mountain has started again and is working on the same basis as the other mines in the district, no union men being employed.
When the strike was called last August an arrangement was made between Mr. Burns, manager of the Portland, and the leaders of the Western Federation, whereby the mine could work employing either union or non-union men.
On the proclamation of martial law in the district a few weeks ago, the Portland was closed by the military. Mr. Burns began proceedings in the United States court for an injunction restraining the military from interfering with the mine, and also brought damage suits against the sheriff of Teller county, Sherman Bell, Gov. Peabody, the Mine Owners' Association and others.
The other directors of this company would not support Mr. Burns in these matters, ordered the suits withdrawn and opened the mine with non-union labor.
This action of the directors has gone a long way toward straightening out the troubles in the district. The property is in splendid shape and a large output is looked for. Most of the former employees of the property have returned to work, those belonging to the union having turned in their cards and given up the union.
Frank Currie, of Victor, is in charge.

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.
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.
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.
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 Shaft House Burned Down March 27 Denver, Colo.—Fire totally destroyed the shaft house of the Portland mine, at Cripple Creek, on March 27. With the exception of some minor injuries to employes on the surface, there were no fatalities connected with the accident. A number of men working underground received notice in time to escape by way of underground connections through the independent shaft.
The loss is placed at $125,000, covered by insurance. The most serious matter is the delay which will result, in the operation of the mine.

Portland Company's Property is Steadily Busy Denver.—Better weather conditions have inaugurated active mining in most camps, and the prospects are that this will be a good year. In the Cripple Creek section the new hoist on the Portland company's property is steadily busy raising ore from the different levels down to the 1,100-foot station.
At the company's No. 3 shaft a good tonnage is coming out from as far down as 1,300 feet. The different ore shoots are not of the extraordinary width of the old workings, but are proving of greater length, with values more equally distributed. The average value of all ores shipped for May will not be less than $35 a ton.
The Captain 700 claim of the Portland company, according to report, is the scene of a rich strike, but the rumor cannot be verified. The working force will be increased and additional drills set in operation.

Improved Method.
A minor but interesting change is the substitution of a round rope for a flat one in installing the new hoist at the No. 1 shaft of the Portland. Flat ropes have prevailed in the past in spite of what seems to engineers in other districts their obvious disadvantages. But if it requires a fire to procure their removal, changes in this regard will certainly be slow.

376Info Title:
Portland Mine Still Works at Depth In the last annual report of the Portland Gold Mining Co., the consulting engineer (Victor G. Hills) writes that in the Portland mine there appears to be a considerable less number of ore-shoots below the 1,000-ft. level than above. Yet the whole truth in regard to the condition at this mine is not discouraging, and as compared to a majority of the mines of the district is rather flattering. Some of the earlier ore-shoots have pinched with depth, while others were only discovered at considerable depths and did not extend to the surface, and some continue to the greatest depths yet reached, and have even increased in size or grade for the last 100 ft.
The condition regarding the ore deposits with depth, is concisely stated thus:
The 900-ft. level was the poorest yet opened.
The 1,000-ft. level was much more productive than the 900.
The 1,100-ft. level is proving poorer than the 1,000-ft. level, although some of the Important veins have not yet been cut.
During the past year work was started to develop the 1,200-ft. level.
Three winzes were started at points far distant from each other and on different veins. On the No. 1 vein the winze was sunk to a depth of 150 ft. to water-level, all in good ore, and drifts were started at the bottom with the purpose of making this the next general level of the mine, and thus save some expenditures in shaft stations and long cross-cuts. Drifts were run on this vein 27 ft, all in ore, when rising water decided the abandonment of this level, and drifts were started at an even 100 ft. below the 1,100-ft. level. This drift is now 114 ft. long and still in ore, and it is not known whether the shoot will be longer or shorter than on the level above. The grade of the ore is decidedly better than on the 1,100-ft. level.

Portland Mine During 1906 According to the printed annual report of the company, the great Portland mine, the banner producer of the camp, made a total output of 103,614 short tons of ore, valued at $1,932,083.
This represents a decrease of 5,619 tons and nearly half a million of dollars in value as compared with 1905. This is accounted for by the closing of shaft No. 1 for 40 days by a fire on May 6, which destroyed the surface equipment about the shaft.
The average total value per ton was lowered by the company's shipping 11,348 tons of low-grade oxidized ore for fluxing purposes at the mill. The grand total production from this famous mine from April 1, 1894, to December 31, 1906, amounted to 775,110 short tons, with a gross value of $25,034,411; it netted $7,147,080 in dividends.
With two years of high-grade ore reserves in sight, exclusive of low-grade rock, the outlook for an increased production in 1907 is very bright. Total development work includes 71,950 feet of drifts, 99,832 feet of crosscuts, 10,843 feet of raises, 4,314 feet of winzes, and 11,513 feet of sinking, the aggregate being 37 miles and 3,092 feet of workings.

Portland Shafts Deep Workings Denver.—Some remarkable and very gratifying results are being realized in the deeper development of the great Portland mine at Cripple Creek. The company is clearing out all of the upper workings, extracting all the ores, even the lower grades that were left standing in the various levels and slopes, with the view of putting them through a large cyanide mill to be erected at the mine, and at the same time carrying on systematic exploration below the 1,000-ft. levels.
At the present time it is breaking ore for shipment at greater depth than any other in the district, and it is believed that the ore bodies opened in the lowest levels alone are sufficient to keep the property in active operation for years.
In shaft No. 2 work is progressing at a point 65 ft. below the 1,200-ft. level and will be carried down to a point 150 ft. below, when a station will be cut and laterals extended. This will be known as the 1,350-ft. level, but in reality it will be 1,512 ft. below the surface.
Already an immense amount of work has been done on the 1,200 level of No. 2 shaft, where winzes have been sunk in several places on the big ore shoot.

41Info Title:
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.
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.
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.
It is known that the company has been experimenting on the dump ore for some time at Colorado City, and is now
erecting a small plant (10-stamp mill) near the mine. They are proceeding carefully, spending probably not more than $15,000 on the outfit.
The method will be to convey the ore automatically to the mill for crushing, pass it over concentrating tables, and then
cyanide. 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.
It would seem wise, judging by the experience of the Stratton's Independence company, to lease the upper levels of the property, instructing their superintendent to watch the timbering and attend to the general supervision of the lessees.
Twenty or thirty sets of brains are better than one in following and discovering ore, and should the Portland company decide to lease the upper workings, I believe their experience would be even more gratifying than that of the Independence, which, after losing some $50,000 in one year on company account, made a profit next year of $1,000,000—the mine making $500,000 and the lessees, $500,000.

Roosevelt Drainage Tunnel Struck Large Flow of WaterCripple Creek Drainage
Denver Correspondence
On Friday night, Nov. 11, at a point 15,956 ft. from the portal of the Cripple Creek deep-drainage tunnel, a large flow of water was struck and so suddenly that some of the men employed barely escaped with their lives.
At present the flow is about 12,000 gal. per min. from the portal, but it will probably decrease somewhat from that.
In the C. K. & N. property, just above the drainage tunnel on Beacon hill, it is stated that the water has dropped 70 ft. during the last four days.
The Portland mine is said to be dry in its lowest workings, which will save $10,000 per month in pumping expenses.
The El Paso mine is also dry and work will be commenced at once in the 1000-ft. level.
No official measurements of the lowering of the water in the mines have yet been taken but it is said to be receding in all but the extreme eastern mines of the district.
To date the approximate cost of the tunnel has been $545,000 and it was commenced in July, 1907; the depth of the tunnel below the average water level in the mines of the district is about 730 ft. Its course is north 44 deg. 20 min. east for 14,845 ft. to a point 65 ft. east of the main shaft of the El Paso mine on Beacon hill and thence north 70 deg. east toward the Vindicator shaft on Bull hill.
At the heading where the work is going on the rock is comparatively dry. Whether the whole district will be permanently benefited by this new flow of water, will be definitely known in a few days.

Portland Dry Below 1500-Foot Portland—One of the permanent good effects of the recent flow of water encountered in the deep drainage tunnel is the fact that the Portland mine, on Nov. 14, was dry below the lowest or 1500-ft. level, and it is considerably over a mile in a straight line from the tunnel heading to the above mine, which in the past has produced gold ore worth $35,000,000, and paid nearly $9,000,000 in dividends.
It is now believed that the entire camp will be drained, making an average of 730 ft. in depth over the whole district, which can now be mined without the enormous cost of pumping hitherto involved.

Deep Mining in Cripple CreekCRIPPLE CREEK DRAINAGE.
———
Engineer T. R. Countryman reports the flow through the portal of the Roosevelt tunnel at Cripple Creek, Colo., as about 8,000 gallons a minute. The recession in the Battle mountain shafts is 3 in. a day and in other parts of the camp the average fall is about the same.
In the main tunnel the heading has passed through the Black Bell water course and is now in hard and closed ground, with little water being opened. Three-fourths of the water coming from the tunnel is from the C. K. & N. vein, which is the chief water course of the district.
The tunnel has drained the Portland mine on the 1,500 ft. level and the announcement is made from the company's offices that a force of men will be put to work early in December sinking winzes from that point in the mine. It is expected that within the next few months a new level will be made ready for development.
The management of the Portland Co. is of the opinion that the deep drainage tunnel has solved the water problem so far as its own property is concerned, and that the water level will continue to drop at a rate that will keep in advance of development work.
The water has receded 3 ft. in the Gold Coin Shaft, which is better than was expected. Some recession has occurred in the Strong shaft just east of the Gold Coin. With the possible exception of the Vindicator and Golden Cycle shafts, all of the deeper mines of the district will be immediately affected.
After being filled with water since 1907, the Stratton’s Independence has recovered the 1,050-ft. level of the main shaft and work has been resumed there by Davis and Hyler of Victor, who have begun taking out ore they left when water drove them out.
Little development has been done at this depth and it is expected that some of the ore shoots found in the upper levels will be found there.
In drifting south on the C. K. & N. vein from the Fuller crosscut in El Paso territory values have been encountered to the great depth 1,350 ft., which is 500 to 700 ft. deeper than it has been possible to open ore in the Cripple Creek district before.

191Info Title:
Portland Mine Drains The Portland has recovered its 1500-ft. level, because of the increased effectiveness of the Roosevelt deep-drainage adit, which is now draining the mining area at the rate of 82 ft. per month. This will make possible the mining of the deeper levels and, presumably, an increased production of high-grade ore.

127Info Title:
Portland Mines Happenings At the Portland Gold Mining Company's mines in Victor there has been installed a complete equipment for life saving and fire fighting. This step has been taken as a precaution against serious accidents arising from foul mine gases and fires. A corps of twenty men have been instructed in the use of the apparatus by the United States mines rescue service.
As a result of drainage through the Roosevelt tunnel, the Portland mine is now free from water, and preparations are being made to prosecute development work in the lowest level.
Stope filling with mill tailing is another innovation which has been adopted during the past year. This has a double advantage in that it enables the company to take care of its old stopes at less expense than before, and at the same time leaves the surface of the property available for mining work.

Portland Gold Mining Company Annual Report 1918 AbstractsProperty: mines and mills at Cripple Creek, Colorado.
Operating Officials:
G. M. Taylor, general manager
Fred Jones, superintendent at the mine
T. B. Crowe, superintendent at the mill
Luther Lennox, assistant
and Merrill Metallurgical Co., consulting metallurgists.
Financial Statement: the net profit in 1918 was $196,596. The balance from 1917 was $278,383, and that carried to 1919 was $127,622.
Current assets total $395,966, and liabilities $14,052.
Dividends: the total last year was $300,000, making $11,267,080 to date.
Development:
there was accomplished 8071 ft., making 63 miles in the Portland mine.
The Independence mine has 17 miles of openings.
The branch tunnel from the Roosevelt drainage-tunnel to No. 2 shaft of the Portland, at a depth of 2131 ft., was connected during the year.
At the end of 1918 the main shaft was sunk to No. 21, or the drainage-level.
Development of No. 1 vein will soon be under way.
The Lee No. 5 orebody was cut by the tunnel cross-cut, and driving is opening high-grade ore.
Generally the outlook is promising.
Production:
the Colorado Springs mill was closed on March 31, and the Victor mill on July 30, leaving the Independence in operation.
The extraction at the last named was good, but the profit was small.
Almost without exception, every improvement devised to reduce costs was immediately offset by some increase in cost of labor or supply entering into the extraction of gold.
The output was 53,887 tons (Colorado Springs) valued at $1,120,851, and 522,756 tons (Victor mills) worth $1,071,925.
The output to date is 3,949,248 tons, worth $48,773,378 gross.
Experiments were made on the tailing at Colorado Springs in an endeavor to devise a process for extracting potash therefrom. This material contains 7% K2O, and there is about 2,000,000 tons of it awaiting treatment.

Portland Mines "The richest ever handled in the ore-house at No. 2 shaft of the Portland Gold Mining Co.," is being mined at a depth of 2131 ft. from two veins under development from the Roosevelt tunnel, according to G. M. Taylor the general manager.
On No. 1 Portland, the ore as broken from 6 ft. width assays from 15 to 25 oz. per ton, while the eastern core of the vein, an 18-in. streak, samples 160 oz. A 4-in. streak on the western side samples 60 oz.
The shoot on the Lee No. 5 vein has been proved for 200 ft. south, and has been carrying 5 and 6-oz. ore. but at a point 30 ft. distant from the junction of the Lee and the No. 1 Portland, a sample taken gave 284 oz.
It is expected that the shoot at the junction will be the richest opened in the mine. The elevation at the collar of the Portland No. 2 shaft is 10,244 ft., and at the point of discovery 8113 feet.
