Annual Review.
Popularity of Cyanidation.
At the annual meeting of Stratton's Independence, Ltd., held at London on December 19, the erection of a mill on the company's property on Battle mountain was considered.
Elaborate sampling of the mine and dump has been carried on this year to determine the quantity and value of the ore available for treating by cyaniding processes. The results were encouraging.
Now that most of the mines have got to a stage where the greater part of the ore is low grade, ranging between $4 and $12 per ton, the cyanide process and its modifications seem to be the only means by which this ore may be treated at a profit.

Denver, Colorado.
Competition Between Cyanidation and Chlorination.
—New Mill.
With the 16% reduction in the output for 1906 for the Cripple Creek District, compared with that of 1905, has come a corresponding pressure for the reduction of treatment charges. Cyanidation has locked horns with chlorination in what promises to be a death struggle and all who are interested are anxiously awaiting the outcome.
It is said that Stratton's Independence, Ltd., is planning the erection of a cyanide mill.
Altogether, it seems as though cyanidation were destined soon to triumph. Bromo-cyanidation will now have a fair chance, and it would not be strange if it were to make a better showing than it has in previous trials.

H. E. NELSON, who has been superintendent of construction for the Golden Cycle mill at Colorado City, has resigned to take charge of the construction work of the new mill of Stratton's Independence at Victor, in the Cripple Creek district.

For several years past Colorado metallurgists have been attempting to solve the metallurgical puzzle presented by the low-grade ores of Cripple Creek. Millions of tons of ore running from $3 to $10 per ton have lain on the great dumps for years, while other millions were exposed in hundreds of miles of underground workings. Thus, for some years previous to 1907, the issues were clearly presented, first, to eliminate roasting the ores if possible, and, second, to eliminate freight charges by building mills at the mines.
It will, of course, be understood that until a way of eliminating the roasting of the tellurium ores was discovered, it would be useless to erect mills at the Cripple Creek mines where roasting costs even more than at Colorado Springs.

The first great plant to be erected at the mines was that of the Stratton Independence Co. nearly two years ago. Little information is available concerning this, except that the method of treatment followed was fine grinding of ore followed by cyaniding.
Owing to the low grade of this company's dump ores the mill has not so readily proved successful up to the present time as it might had it treated the dumps of other mines.

Denver—Both smelters and chlorination mills have been dropping behind in the race for tonnage, in accordance with the rule that as the grade of ore drops the cheaper but less efficient processes become economical.
The beginning of a further step is seen in the introduction, by Philip Argall, of concentration into the mill of Stratton's Independence, for treating low-grade and dump ores. It is found that 30% of the gold in these ores can be so saved. By supplementing cyanidation, a total saving of 65% is effected.
The low value of the ore makes it unprofitable to attempt a closer saving.

Denver. Nov. 5—At Stratton's Independence the third chilean mill is being erected, which will bring the capacity of the mill up to 8000 tons per month. The buildings are completed, but the usual delay is being experienced in the arrival of machinery. An automatic power shovel of 60 tons per hour capacity was placed in position in the deep cut in the dump this week, and will be in operation in a few days. The mine continues to make a fairly steady production under lessees and company operation, the output being about 2000 tons per month, worth $50,000.

The striking feature of the year, metallurgically, was this development of mills. Stratton's Independence plant has made so good a record as to lead to enlargement.

At a banquet to celebrate the completion of the second unit of cyanide plant for the treatment of low grade dump ore at Stratton's Independence, Cripple Creek, Philip Argall gave a speech containing interesting reminiscences.
Eighteen years ago he commenced his connection with the cyanide process by going to Deadwood, South Dakota, in the interests of the owners of the MacArthur-Forrest patents. At this spot in the Black Hills a cyanide plant had been erected and had proved a failure at first, and advice was required.
His second trip was to what is now the Brodie mill at Cripple Creek, where the cyanide process was also a failure. In both these cases the ore was ground fine and could not be leached; this was in the days before slime agitators.
Nevertheless Mr. Argall was firmly convinced that cyanide treatment would be the most suitable for Cripple Creek ores, and by tongue and pen was persistent in his advocacy of its adoption. Indeed he then made a design for a treatment plant which was adopted 14 years later at Stratton's Independence.
His connection with Cripple Creek was renewed in 1907 when he was asked to design a plant to treat the dumps at Stratton's Independence. The gold content of these dumps was much less than the current cost of treatment, and it was obvious that some different method must be adopted. Roasting was out of the question.
He found by experiment that 35% of the gold could be recovered by wet concentration, and that another 35% could be obtained by cyaniding the remainder.
With this 70% recovery the cost has proved to be less than $1.50 in a plant treating 7000 tons per month. This metallurgical improvement should have an important economic influence on the future of Cripple Creek and will make the beneficiation of the low grade sulpho-telluride ores a practical proposition.

During November Shipments from the district to the Stratton's Independence Mill amounted to 8,000 tons of an average $3.00 per ton for a total of $24,000.

Herbert Whitaker has resigned as cyanide superintendent at Stratton's Independence, Ltd., Victor, Colo., to accept a similar position at the Arizona Mascot mine, Crown King, Arizona.

THE BATTLE of the processes has been nowhere waged more vigorously than in Colorado, where chlorination and cyanidation have competed with varying success during two decades for preference in the treatment of the ores of Cripple Creek.
Cyanidation is the victor, for it has been apparent for several years that the application of tube-milling and cyanidation to the tailing from the chlorination plants had placed these in a humiliating position. The successful plant at Stratton's Independence is, of course, the most up-to-date exponent of the cyanide process.

The report of Stratton's Independence, Ltd., for the year ended June 30, 1911, shows that the net profit for the year was £21,000, of which sum £12,500 were paid out as a dividend. Development work to the extent of 9186 ft. was done in the mine, of which 19 per cent, was in the form of crosscutting.
In addition to ore of shipping grade the company for the first time produced low-grade milling ore amounting to 7440 tons. The greater part of this was sorted out of the ore rejected by the lessees and sent direct to the mine breaker, while the waste went back into the mine for filling. Formerly both products, the low-grade milling ore and the waste, went to build up the ore-house dump. Now everything that passes through the ore house is worked up daily and finally disposed of. The total production of the mine was 25,825 tons, having a gross value of $534,068 and a value of $389,008, after deducting freight and treatment charges.

The mine breaker and roll mill began operations in October, 1910, and averaged about 825 tons per month during the nine months of the fiscal year in which the plant was in operation.
In addition to the changes required to combine the wet mill with the mine breaker and roll mill, the permanent breaker plant of 70 tons per hour capacity was erected in the clearing made in the heart of the dump by previous milling operations.

The fourth Chilean mill was erected as a reserve, and six more slime tables added, together with new distributers and a new settling tank in the cyanide department. These additions brought up the milling capacity from 7500 tons per month to 10,000 per month, an increase of 33 per cent. The sum of £13,900 was charged to mill construction during the year. The 109,800 tons of ore milled during the year averaged 0.157 oz. per ton. The total recovery was 71.5 per cent.; 43.65 per cent, by concentration and 27.85 per cent, by cyaniding.
The total milling cost is given as $1.52 per ton, which agrees closely with Philip Argall's estimate made in 1907 as to the probable cost on a basis of 10,000 tons per month with 70 per cent, extraction.

Denver Dec. 9—The Argall mill, of Stratton's, reports its usual 10,300 tons treated.

Denver Dec. 22—The drainage tunnel after all has not been an unmixed blessing to the mines of the Cripple Creek district, for Stratton's Independence has had to close down its mill for want of water.
Wilson Creek, which was largely supplied by the discharge of water pumped from the mines, is bone dry, and so are some springs from which Stratton's got its supply, and the drainage tunnel, combined with the zero weather, has completed the drought.
The average recession of water, according to Engineer Countryman, is now 10 ft. per month in all the deep shafts.

Much of the low-grade ore is now being treated by mills at the mines, like at the Stratton's Independence which is taking 10,000 tons of $2.75 ore.

THE ANNUAL MEETING of Stratton's Independence focuses attention again on the admirable management of that property, affording a gratifying contrast with the boom days, when everything was subordinated to market requirements.
During the past financial year the output was worth $758,977, bringing the total gross production of this famous mine to $21,820,562.
The mine did exceptionally well last year by reason of the yield of high-grade ore from the newly discovered Mill veins, which are now almost exhausted.
In 1911 we published a description of the milling methods at Stratton's Independence from the pen of Mr. Philip Argall, the actual cost of milling confirming with exactitude the original estimate on a new method of ore treatment.
The figures given by Mr. Argall covered only the last three months of the financial year ending June 30, 1911, during which months the mill for the first time attained a capacity of 10,000 tons per month. This capacity is easily maintained, but through stress of weather the mill was idle about one month last winter, which reduced the average tonnage treated to 9366 per month.
Nevertheless the original estimate of $1.52 based on milling 10,000 tons per month was not exceeded, as shown below :

This record speaks for itself, but we are glad to add to it our hearty appreciation of the excellent technical and administrative work done by Mr. Argall.
The old mine is nearly exhausted and it is but gleanings that are now being garnered, as compared with the prolific production of an earlier period, yet it is fair to say that the story of this British financial excursion into Colorado has been greatly redeemed in the last chapter.

The report of this company operating the gold mine at Cripple Creek, Colorado, for the year ended June 30, shows that both the mine and the dump continue to yield profits. It is not necessary to recapitulate the history of this mine, as we have given it on previous occasions.
Of late years, operations have been confined to re-treating the dump by the method described by the manager, Philip Argall, in our issue of November, 1911, and to the working of parts of the mine by the company and by tributers. In 1908 the capital was written down by reducing the shares from £1 to 2s. 6d, and stands at £125,000.
The report now issued shows that the output of ore by tributers was not as great as during the previous year, but that the ore produced by the developments conducted on behalf of the company showed a substantial increase. In all probability the production by tributers will still further decline, and the yield of low-grade ore on company account will increase.
The new vein system, called the 'mill veins,' discovered a year ago, promises to lengthen the life of the company.
The output of ore from the Independence mine was 10,455 tons produced by the tributers, containing gold worth $304,464, and 4550 tons produced by the company, having a content of $116, 518; in addition 1922 tons containing gold worth $48,599, was taken by tributers from the Washington claim, and 1567 tons from the dump containing $35,735, also by tributers.
The net returns from the sale of the ore amounted to $377,480, of which $87,156 was received by the company from its own ore, and $108,752 from royalties.
The company also won 13,019 tons of ore which was treated by the company's plant, containing $67,887, and yielding a profit of $20,784.
At the company's treatment plant, 99,372 tons of dump-ore as well as the 13,019 tons of mine-ore was treated, yielding 18,833 oz. gold.
The profit at the plant was £13,778, the net proceeds from sale of ore on company's account £17,970, and the company's royalty on tributers production was £22,432.
The cost at the mine was £14,122, administration expenses were £6954, London expenses £2209, and allowance for depreciation £3505, leaving a profit of £27,465, out of which £25.000 has been distributed as dividend, being at the rate of 20 per cent.

Stratton's Independence, thanks to Mr. Philip Argall, continues to make steady returns. Out of $2.80 dump ore, a profit of $1 is being squeezed; and even $3 ore is being mined and milled profitably. A new shallow adit has been extended from the floor of the old ore house to the Portland boundary, with crosscuts under old surface workings, opening up at least 150,000 tons of remnants that can be extracted profitably.

Stratton's Independence
The experience with lead acetate at Stratton's Independence mill, at Cripple Creek, has been confined to its use in forming the zinc-lead couple in the zincboxes.
The zinc is cut by hand and dipped in a 3 to 5% solution of lead acetate before using. In the earlier experiments on Cripple Creek sulpho-tellurides the use of lead acetate as added to agitation tests on slime gave rather negative results, and it has not been used in the actual ore treatment since.

It is not necessary here to recapitulate the history of this famous gold mine at Cripple Creek. Colorado. Suffice it to say that, of late years, operations have been confined to re-treatment the dump by the method devised by Philip Argall and by the removal of any remaining ore of high grade, by the company and by tributors. The report for the year ended June 30 last shows that the likelihood of finding rich ore is decreasing and that the profits will not be maintained.
During the period under review, 5296 ton of ore was mined by the company, and sold to the smelters for £19,943 gross, or £13,851 net after payment for freight and treatment; 10,313 tons was mined by the lessees, and sold for £47,325 gross or £33,661 net.
The royalty accruing to the company from the tributors' ore was £11,103.
At the low-grade plant, 104,111 tons of dump material and 25,999 tons of mine ore was treated yielding 15,707 oz. gold, of which 6891 oz. was recovered in concentrate, and 8816 oz. in bullion.
The operating profit at the mill was £26,989, of which £3254 was credited to the mine for low-grade ore treated.
The general expenses at the mine were £11,659, including £4755 for development, and £6703 administration expenses.
London expenses absorbed £2150, settlement of the Portland company's claim £2062, settlement of the Moore Filter company's claim £859, income tax £717, and £1752 was allowed for depreciation.
The net profit for the year was £17,777, which added to the balance brought forward made a total disposable amount of £29,680.
Out of this, £25,000 has been distributed as dividend, being at the rate of 6d. per 2s. 6d. share.
As usual the report contains a full statement of operations written by the consulting engineers and managers, Philip Argall & Sons.
We published an article by Philip Argall on the present scheme of operations in our issue of November 1911.

The Estimated production of the following district mill during November is as follows:

We have on many occasions referred to the history of the Independence gold mine at Cripple Creek, Colorado, and need not recapitulate here. During the last few years, operations have been confined to re-treating the tailing dumps according to a method devised by Philip Argall, and the removal from the workings of any remaining high-grade ore by the company and by tributers.
The report for the year ended June 30 last shows that 3899 tons of ore was shipped to smelters on the company's account and 7783 tons on the lessee's account, realizing £14,173 and £33,114 respectively gross, or £9651 and £22,782 net after payment of treatment expenses and freight.
The royalty accruing to the company on the lessees' ore was £7280. At the mill and cyanide plant, 45,683 tons of low-grade ore from the mine and 88,192 tons of dump tailing were treated, yielding 7654 oz. gold in concentrate, which was shipped to smelters, and 7764 oz. in bullion, making a total extraction of 15,418 oz. or 2.3 dwt. per ton.
The profit on milling and cyaniding was £20,995. After all expenses were paid, a profit of £19,136 remained, out of which £6500 has been distributed as dividend, being at the rate of 5%.
It is expected that the mine will continue to yield shipping ore, but on a smaller scale, and that low-grade ore and dump material will keep the treatment-plant occupied for two years.
Negotiations were in hand before the war for the acquisition of a new property, but all efforts in this direction are now suspended.

Stratton's Independence Limited.
The extraordinary general meeting of the shareholders held on May 17 was the occasion for bringing out a number of most interesting facts about the celebrated mine owned by this company. The story of the discovery, of the organization of the first Stratton's Independence Limited, of the over estimates, high prices of shares, and the disaster that followed is already familiar.
In 1908, the lower levels had been fruitlessly explored and the upper levels were inaccessible because of a cave. A mill had been built to treat the accumulated dump ores, but the company was in debt locally to the amount of £25,000 and there was no working capital. Heroic measures were adopted.
The company was reconstructed on a basis of £125,000 capital in 1,000,000 shares of 2s. 6d. each in place of £1,100,000 in £1 shares.
The old shares were exchanged for new on a basis of 1s. 6d. paid, and thus cash to pay the debts and supply working capital was secured. Many of the shareholders had paid high prices for their shares, and the old company died with an unenviable record of failure.
The mine, however, was good. To date it has produced gold to a value of £4,850,000 or $23,573,500. Of this, W. S. Stratton won before sale of the property $3,985,440, the first company produced $15,064,320, and the second or present company $4,523,740.
The old company paid in dividends $4,748,989, while since its organization the new Stratton's has distributed 1s. 10½d. per share to which was added 6d. at the meeting. Thus, it has paid 2s. 4,5d., nearly the par value of its shares, and has in reserve as a result of the action then take an sum equal to 1s. 3d. per share.
On its merits as well as by contrast, these results redound greatly to the credit of the managers and the engineers in charge. The whole story indeed is a brilliant one of saving the maximum from a wreck.
The total dividends paid by the two companies is materially above the net value of the mine, $5,000,000, as fixed by the examination made when British capital first went into the enterprise.
When the new company was formed, Mr. Philip Argall estimated a profit of $1 per ton when working at the rate of 10,000 tons per month on $3.60 ore. The profit has been substantially that amount despite the fact that the sampling of the dump by the engineers of the old company proved inexact, the ore averaging $3 instead of $3.60. Mr. Argall has been able to reduce costs and increase extraction enough to compensate.
On the whole, the company has been fortunate in the amount of ore found in the upper levels, £65,000 having been won from the 'mill veins.' A good mine dies hard, but it dies.
Mr. Argall has kept his company fully informed as to the exhaustion of both mine and dumps, and the time has come when the work must be stopped.
Negotiations for purchase of other dumps, in particular those of the Portland Gold Mining Company, proved fruitless, but they did result in an offer from the Portland company to purchase the mine and mill upon what are, we believe, excellent terms for all concerned.
Briefly, the Portland is to pay £65,000 plus the invoice of supplies, and Stratton's Independence is to keep the property till the end of June. Since a surplus of £20,000 has been accumulated, the close of these various transactions will leave the company with nearly £96,000 on hand. This we believe to be very good business.
Anyone familiar with the local situation will recognize that the Portland with its big dumps right at hand can pay a larger price for the Stratton's mill than could any other company. It is also true, owing to the relations of the two mines, that the Portland management can win whatever ore may still remain in the property at less cost than it could be mined by Stratton's working independently.
The bargain is, we repeat, one of the satisfactory kind where each party to it takes a profit. We are confident that under the management of Mr. G. M. Taylor, the Portland will derive full benefit from the purchase, while the excellent record of service Mr. Argall has with Stratton's is the best guarantee that the fund now available will be wisely invested if the programme of purchasing another mine be followed.
A small number of the shareholders at the meeting expressed a strong preference for dividing the whole sum remaining rather than making any new venture, however promising, at this time, but the vote was heavily in favour of the plan outlined by the directors.
Mr. Argall stated to the meeting that, while his firm had four different properties under study, he was not prepared at this time to recommend a purchase. It was therefore left that until a satisfactory property was offered, matters are to stand as they are, and if no suitable investment be found within a reasonable time, the chairman agreed to recommend dissolution of the company.
The policy or unpolicy of such reinvestment, made by a company as a whole in place of individually by shareholders, is too broad to discuss at this time. We may, however, congratulate the present shareholders of Stratton's on having received in dividends a sum substantially equal to the par value of their shares and having a sum in the treasury of the company adequate to undertaking a wholly new mining enterprise.

During January the Portland Independence mill treated 39,010 tons of $2.07 in average value, total $80,750.70

The Portland Independence mill, Cripple Creek during February, a month where the weather, deep snow preventing movements of ore, both by team and by rail, still produced 37,000 tons with an average value of 2.06 for a total of $76,220.

The Portland company has announced a new schedule of treatment charges on low-grade mine and dump ores, as follows:
Up to $3 value, $2.00 per ton
$3.50 at $2.25 per ton
$4 at $2.50 per ton
$4.50 at $2.65 per ton
$5 at $2.75 per ton.

Of the tonnage treated during September the Independence mill of the Portland Gold Mining Co., near Victor, treated 25,810 tons with an average grade of $2.09 per ton.

Portland G. M. Co.'s Independence mill, Victor, in October treated 27,321 tons, average grade $2.07 per ton, gross value $56,554.47

The Independence mill of the Portland company, treating low-grade mine and dump ores, is electrically operated and the tonnage treated will be normal.

The Portland Independence cyanidation-concentration mill at Victor was the only mill actively operated throughout 1919 in the Cripple Creek district.

During February the Portland Gold Mining Co.'s Independence mill, near Victor, treated 18,841 tons of ore with gold value of $2.07 per ton.

This ore will mill about $3 per ton.

The Portland company's Independence mill at Victor treated 10,667 tons of an average value of $3.64, and the total bullion amounted to $71,765 during June from the Cripple Creek district.

The Independence mill of the Portland G. M. Co., at Victor treated 20,022 tons of ore averaging $3.10 during July.

During August the Independence mill of the Portland Gold Mining Co, near Victor, handled 18,291 tons, valued at $62,104.

During October the Portland company's Independence mill handled 18,556 tons of $3.70 grade.

The Independence mill continues operating on low-grade ores, the higher grades being shipped to the Golden Cycle mill at Colorado Springs.

The January output from the Portland G. M. Co.'s Independence mill was 17,556 tons of an average value of $5.56 per ton, bullion value $97,611.36

The filled stopes in the Hidden Treasure section of the Portland are to be tapped and the ore conveyed by underground tram to the Independence, to be there hoisted for treatment at the Independence mill.

A fill on the old Florence & Cripple Creek railroad (now dismantled), near Hollywood, made from waste from the Strong mine at Victor, in the days of high-grade production from that property, when all waste was hauled by the railroad free under the 'right-of-way' contract, is now being hauled to the Independence mill of the Portland Gold Mining Co., where it is netting around $10 and $12 per ton.
Under a contract, $1 per ton was paid for the privilege of removing and shipping this rock.

July production of the Cripple Creek district as reported from the Golden Cycle, Portland, and Lincoln companies' mill totaled 39,592 tons with a gross value of $394,580.78.

The Ajax Mines Leasing Co. is now shipping steadily to the Independence mill of the Portland company near Victor.

The Ajax mine now has 25 sets of lessees operating, and daily shipments go to the Independence mill of the Portland company; higher-grade ore goes to the Golden Cycle mill at Colorado Springs.

A third shift has been put to work at the Independence mill of the Portland Gold Mining Co., and the plant is now operating at capacity on lowgrade ores; company and custom ores are treated.

Increased tonnage is the order of the day at the Portland. The tonnage to the Independence mill has been increased 50% while the treatment cost has been lowered.
Perry O. Harrison has succeeded G. M. Taylor as manager. Thomas B. Crowe, mill manager for many years, has resigned and left the service of the company.
