Page: 39 [view image]REPORT UPON THE PROPERTIES OF THE DAHLONEGA CONSOLIDATED GOLD MINING COMPANY Dahlonega, Lumpkin County, Georgia, by Arthur Weld, M. E. [Mining Engineer], Milwaukee, Wis [Wisconsin].
This property is situated in the 5th, 11th, 12th districts of the first section of the State of Georgia, -- (chiefly in the 12th district) and consists of 4,671 5-6 acres of land, about 120 quarter-acre lots in the town of Dahlonega, 6 gold mills aggregating 110 stamps, 1 saw mill [sawmill], 1 grist mill [gristmill], 1 tannery, 1 chemical laboratory and assay office, 6 water-powers [waterpowers] aggregating about 500 H. P. [horsepower] and about 45 miles of ditch carrying, according to the season, from 800 to 1,200 miners' inches of water.
There are about 30 dwellings, and also a considerable amount of machinery, besides that in active use in the mills already enumerated.
Page: 40 [view image]The Water Supply.
Assuming the average capacity of the canal to be 1,000 miners' inches (which is equivalent to 12,000 gallons per minute) it represents an amount of power which would be of the greatest value at any and all times. Consequently, if in the future it might be deemed advisable to discontinue the present method of mining, (the hydraulic) for some other system, the value of this artificial water course [watercourse] for various other purposes would be in no wise diminished.
In the preliminary recapitulation no mention was made of the Etowah canal, as this canal is not entirely completed. It will require about $6,000 to finish this work and it will increase the supply of canal water by a minimum of 600 miners' inches (the equivalent of 7,200 gallons per minute.) About 20 miles of this canal are completed.
The minimum capacity of the two canals combined would be 1,400 miners' inches, with an average of 1,800 miners' inches. Used as horse-power [horsepower] alone, this would represent at least 900 H. P. [horsepower] If, however, the mere commercial value of the water for ordinary mining purposes were considered, it may be noted that if the waters were sold to local miners at a low rate, say 8 c. [cents] per inch for the day of 24 hours, the canal might be made to produce an income of $144.00 per day.
Aside from the canal, 5 other water-powers [waterpowers] belong to the property. These are the dam on the Yahoola with a minimum of 60 H. P. [horsepower], 1/3 of which belongs to the Mary Henry Mining Company; the dam above the Yahoola mill on the Yahoola river with a minimum of 60 H. P. [horsepower], from which both the Yahoola and Hand mills are driven; the dam on the same river at Findley mill, also 60 H. P. [horsepower]; the dam on Cane Creek above the Barlow mill, about 75 H. P. [horsepower]; the dam at

Page: 43 [view image]
Jay, where the saw mill [sawmill], grist mill [gristmill] and tannery are situated, on the Etowah River, 100 H. P. [horsepower]
It will thus be seen that as far as cheap power is concerned the property in question is exceptionally well supplied and possibilities for almost any kind of manufacturing, even without interfering with the mining operations, are easily within hand.The Mills.
There is a 20-stamp mill situated on the Yahoola river at the most northerly point of the Company's gold mining operations. To avoid needless repetition in future, it may be said that here, as well as in all the mills, the stamps are of 450 pounds weight. The use of the light stamps is the result of experience in this section, as it was formerly the custom to use stamps of the standard Western weight, but the extremely friable material could not be fed fast enough to keep the shoes off the dies.
For the same reason all the mills in this section are fed by hand, as no self-feeder could possibly handle the class of material which the nature of the ores combined with the transportation by water delivers at the mills. But the low wages in this locality make hand-feeding inexpensive, while it is well admitted that when performed by careful and experienced men the results are even better than the performances of the best self-feeders. In this connection it may be mentioned that one man feeds two batteries with ease, consequently in a 20-stamp mill only two men are required on each shift, of whom one in immediate charge receives $1.00 per day of 12 hours, and his associate 90 c. [cents]
The Yahoola Mill is driven by a Hunt turbine in excellent condition, 3 feet in diameter, capable of furnishing a minimum of 35 H. P. [horsepower]
The mine consists, firstly, of a large open quarry containing very large deposits of ore varying in assay value from $3.00 to $9.50. It may be noted here, that with no better tool than an ordinary "bumping table
Page: 44 [view image]$70.00 concentrates have been made in this mill from an average run of ore from this open quarry. In addition to the quarry there is a large amount of virgin surface and several tunnels and shafts, all of which have developed excellent material.
The water supply for piping and sluicing is drawn from a branch of the main canal 2 ½ miles in length, which also supplies the Hand and Lawrence mines. Here, as at all the other mines in this district, no mine water is used for battery purposes In most cases the battery water is drawn directly from the dam, or is conducted to the mill from neighboring branches, thus entirely avoiding the use of mine water.
There is one house on this property close to the mill for the use of the mill men.
The Hand Mill.
Half a mile lower down the Yahoola river from the Yahoola mill is situated the Hand Mill -- a 20-stamp mill in first class condition, which has run uninterruptedly for upwards of 20 years. It is driven from the same dam and canal as the Yahoola by a Wilder turbine, 26 inches in diameter, with a capacity of 30 H. P. [horsepower] minimum.
The mine consists of a large open cut, and numerous tunnels, one of which, a prospecting tunnel less than 100 feet long, was cut on veins aggregating a width of ore amounting to over 40 feet. At the mouth of this tunnel is an inclined shaft driven to prospect one of these veins and a 12-foot overshot wheel stands at this point for the purpose of pumping this or other shafts in the neighborhood. The ores vary in value from $2.00 to $20.00, and concentrates have been made running to $150.00, and in one case to over $1,000.00. There are a number of extraordinarily rich shutes on this property, one of which recently opened repeatedly gave assays of upwards of $700.00. At the same time it must be remembered that these shutes are small, while the deposits of low grade ore, say of a value of $3.00 to $4.00, are very large. There are several large "soft belts"
Page: 45 [view image]
on this property which are taken down with perfect ease by the pipe alone and which are rich in coarse gold.
On one of these lots No. [Number] 999, there is a very large deposit or virgin surface accessible to piping water from the canal and within easy reach of the mill by a line of sluice boxes. Attached to the mill is a blacksmith's shop furnished with the necessary tools for ordinary repairs.
There are five houses on the property.
The Findley Mill.
About 1 mile lower down the Yahoola river is situated the Findley mine and mill, unquestionably one of the most desirable properties in the South. The mill is a 40-stamp mill in the best of condition, 20 of the stamps being entirely new. It is driven from a 17-foot dam by a 23-inch Leffel turbine furnishing 60 H. P. [horsepower] The high, steep hill, rising abruptly above the mill, has always been considered as the heart of the Georgia gold belt. On the hill is situated the celebrated "Findley Shute," a wonderfully prolific pocket vein from which alone at least $200,000.00 have been taken out and which does not appear to be exhausted. The hill is also pierced by 4 extensive tunnels and several shafts. There is vast virgin surface and a great number of veins, the latter averaging $5.00 to $10.00 in value, with ore in sight at the present writing for many years to come.
At this point stands a duplex pumping engine of entirely new construction, which driven by water furnishes 600 gallons per minute at an elevation of 463 feet. Using the head of 285 feet as a power, the pump forces 50 per cent [percent]. of the water delivered to the above elevation. The mine is thus more than amply supplied with water at the extreme height of the hill, and at an expense ridiculously small in comparison with what the same result would cost if obtained by the use of steam. I say "more than ample" advisedly, for herein lies an additional value of this pump. The mine does not use more than 25 per cent [percent]. of the capacity of the pump daily and consequently it is possible to furnish other neighboring mines with water under this unusually high
Page:  [view image]
head at a rate much advanced over the ordinary price of canal water.
Nearly all of the ore at this point is wholly suitable for concentration, and concentrates have been made here varying in value, according to the quality of the ore, from $30.00 to upwards of $100.00.
On the lower ground, across the river from the mill, there is also a large vein called the Evans vein, suitable for deep mining, averaging in value $15.00, which gives $70.00 concentrates. Furthermore the mill pond above the dam is filled with many thousands of tons of tailings from all the mills higher up the river. Samples of these tailings have been taken at various depths, from 2 to 12 feet, and they are worth from $1.50 to $20.00, and are all suitable for treatment again. Their value is undoubtedly owing to the fact that in the course of their transportation to the present position an oft-repeated concentration has taken place.
On the western side of the Findley hill are two 40-acre lots belonging to the property called the Boyd lots, which in the course of prospecting, have showed a very rich surface, and several large veins have been located.
The upper tunnel at the Findley mine almost completely cuts the hill, its upper opening being at a point which commands the virgin surface as well as the large group of rich veins. Through the tunnel a line of boxes has been run, thus opening up a portion of the hill, and making transportation to the mill possible, in a manner otherwise impossible. In short, the mine is in every way most advantageously opened and with ore in sight for many years.
There are three houses on the property in good repair, and also a blacksmith's shop.
The Lawrence Mill.
Situated directly in the town of Dahlonega, and run by a 26-foot overshot wheel fed by a branch of the canal which traverses the town, is the Lawrence Mill -- a 10-stamp mill in excellent repair. It is further furnished with an Embrey concentrating table, hoister with wire rope, pump, etc. [et cetera]
Page: 47 [view image]
This mine being entirely underground was abandoned by its former owners owing to the increasing presence of sulphurets [sulfurets], which, while rich, could not be worked by any means at their disposal.
There is one very good house attached to the mill.
The Barlow Mill.
Four miles below the town in a southwesterly direction, and situated in the celebrated Pigeon Roost belt, is the Barlow Mill. This was originally a 40 stamp [40-stamp] mill, but at present contains only 10 stamps, although the mill house is large enough for 60 stamps. The reason for the removal of the other stamps was that at this point, or rather at the present location of the mill, the hydraulicing method can be no longer applied, as the cut has been piped out to such a depth that the necessary fall to transport the ore to the mill is no longer available.
On the Barlow property are situated the richest deposits which have been discovered in this district, notably the so-called Doghead vein. This vein which is situated in the immediate vicinity of the mill may be described as fairly glistening with metallic gold. Few places in the U. S. have yielded more beautiful specimens than those which have been taken from an incline shaft which has only been pursued for the short distance of 36 feet. This ore, after careful and microscopical removal of visible gold, has been assayed repeatedly all the way from $100.00 to upwards of $500.00 per ton. Owing to the presence of coarse gold it is diffcult [difficult] to obtain a truly average sample and consequently it cannot be assumed that any such results could be obtained on the mill as these assays show, but the extraordinary richness of the deposit is unquestioned.
The Barlow Mill is driven by a 40-inch Hunt wheel and the water power [waterpower] is one of the best on the property, its minimum being 75 H. P. [horsepower]
There are 9 houses on this property, with a small farming lot attached.
The property between this mill and the Ralston, 2 miles below it, is considered, and rightly, to be rich in gold, the
Page: 48 [view image]
cuts join one another and while, as already pointed out, in the Barlow cut proper the piping material has been mostly removed, yet this cut abounds in rich shutes, and even larger veins, nearly all of which would well repay individual working, even if the resultant ore had to be hauled to the nearer of the two mills.
In illustration of this, a very considerable vein was opened recently by the prospectors near the Ralston mill which assays $17.00 per ton, and which, in the opinion of the foreman, would supply a 10 stamp [10-stamp] mill for a number of years. This vein could easily be approached from the bottom of the old cut by a short tunnel and then stoped out.
The Ralston Mill.Saw Mill [Sawmill], Grist Mill [Gristmill] and Tannery.
This mill is situated on the same belt as the Barlow and about 1 ½ miles south of it. It is a 10 stamp [10-stamp] mill in good condition and is run by a 3-foot Knight hurdy-gurdy wheel under a pressure of 50 lbs. [pounds] to the square inch -- fed from the canal through an 8 inch pipe. At present this wheel could easily furnish 40 H. P. [horsepower], and were more power desired it could be obtained by enlarging the diameter of the feed pipe. There is still an ample supply of soft belt at this point, as well as numerous smaller deposits of rich hard material. There are five houses on the property.
Situated about 7 miles to the northwest of, and connected with Dahlonega by a daily mail is the little village of Jay, where the saw mill [sawmill], grist mill [gristmill] and tannery of the Company are located. This is one of the finest water-powers [waterpowers], if not the finest in the country, its minimum being 100 H. P. [horsepower] The saw-mill [sawmill] is thoroughly equipped for all kinds of work, being furnished with 3 circular saws, 2 cutting-off saws, 1 lazy saw, shingle machine and planer, moulding machine, etc. [et cetera], and all in perfect repair. The neighboring country is rich in timber of suitable nature for sawing. Just opposite the
Page: 49 [view image]
river from the saw-mill [sawmill] is the tannery, the power being conveyed acros [across] the river to it by means of a wire rope from the saw-mill [sawmill]. It has 24 vats, the necessary leeches, and all other appliances, tools, etc. [et cetera] Chestnut bark is delivered at the tannery for $1.50 per cord -- and thus it would evidently be an excellent location for the manufacture of bark extract. The grist mill [gristmill] stands in a small building adjoining the saw mill [sawmill] and has a good custom. There is a small store and 5 houses attached to this property. The power is supplied by 42-inch Hunt turbine with a minimum effectiveness of 100 H. P. [horsepower] In the immediate vicinity aside from the large timber is a great quantity of second growth hickory inviting the possibility of attaching to the saw-mill [sawmill] the proper machinery for the manufacture of spokes, handles, etc. [et cetera]Miscellaneous.
Aside from the machinery already noted as in active use at the various mills, there is also a large amount of machinery on the property in good condition. Among such may be noted: At the old Gordon mine a good 50 H. P. [horsepower] engine and boiler and a 14-inch high pressure Leffel wheel with a capacity of 50 H. P. [horsepower] At the Barlow is an old style engine and boiler with a capacity of 100 H. P. [horsepower], together with a mass of shaftings, gearings, pulleys, etc. [et cetera], of every description in good condition, which resulted from the instalment [installment] several years ago of a much praised "process" which was subsequently promptly removed for stamps again. At the Findley 3 boilers and 2 force pumps. At the Ralston a 12-foot overshot wheel with 2 Rumsey force pumps (9x14 inch) a second hand 42-inch Hunt turbine in good condition, a "Perfection" bumping table, etc. [et cetera], etc. [et cetera] Also 2 first class combination dump steel ore cars, about 800 feet of track, and many thousand feet of pipe of various dimensions, from 4 feet up to 2 feet in diameter. A schedule of other pipe that is in use is appended. Situated directly in the town is a large store house filled with odds and ends of machinery and tools; in one end of which is a commodious and complete laboratory and assay office with large bullion furnace,

etc [et cetera], chemicals, apparatus, etc. [et cetera], also gold safes. Two first class levels and other surveying instruments and many other articles of usefulness in the work of mining.Timber.
There is timber of all sorts and sizes upon the property in profusion, white, black, red, turkey, post and chestnut oaks, mulberry, (satinwood), cherry, walnut, poplar, hickory (in large quantities), chestnut, ash, maple, locust, the various kinds of Southern pine, including hemlock, and indeed all varieties of timber which flourish in this section of the country. As the timber has been carefully watched and guarded many of the trees have attained extraordinary size, true veterans of the forest, and as no engines have been run hereabout since the almost universal use of water power, even those sections which were formerly more or less denuded of their growth are now covered with a vigorous growth already of considerable size.
