Page: 53 [view image]REPORT UPON THE PROPERTIES OF THE DAHLONEGA CONSOLIDATED GOLD MINING COMPANY. At Dahlonega, Lumpkin County, Georgia, by Joseph Philips, Jr., M. E. [Mining Engineer]
This property is situated in the 6th, 11th and 12th districts of the 1st section of Georgia -- comprising in all some 4,671 5/6 acres of land, 117 quarter-acre town lots in the town of Dahlonega, 6 gold mills aggregating 110 head of 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 35 miles of canal carrying, usually, 1,000 miners' inches. This water (1,000 miners' in. [inches]) is delivered at the different mines at the maximum head of 230 ft. [feet] There is considerable machinery besides that now in use, and about 30 dwelling-houses.The Water Supply.
As I have previously stated, about 500 H. P. [horsepower] can be gotten from streams flowing through or near the property, -- the water right being owned by the Company; in addition to this the water from the Hand canal represents nearly as much more.
In addition to these powers, $6,000.00 will complete the Etowah canal, which will give 600 inches of water at the same head as the Hand canal. All rights for this canal are owned by the Company. Twenty miles are already completed.
Page: 54 [view image]Chemical Laboratory.
This is one of the best equipped private laboratories in the State. A complete set of chemical apparatus is provided, as well as a modern assay office, equipped with gasoline furnaces and a large bullion retorting furnace.The Saw Mill [Sawmill], Grist Mill [Gristmill] and Tannery.
This is located 7 miles northwest of Dahlonega. The minimum power is 100 H. P. [horsepower] The saw-mill [sawmill] is equipped with 3 circular saws, 2 cutting-off saws, 1 lazy saw, shingle machine, planer, moulding machine, etc. [et cetera], all in good repair. The neighborhood abounds in timber.
The tannery is across the river from the saw-mill [sawmill], the power being conveyed by a wire rope. It has 24 vats, all necessary leeches, tools, etc. [et cetera] Bark is delivered to the mill at $1.50 per cord.
The grist mill [gristmill] adjoins the saw-mill [sawmill]. There are a store and five dwelling-houses upon the property.The Lawrence Property.
This property is located in the town of Dahlonega, within two blocks of the court-house [courthouse]. The Company owns about ½ of a mile along the strike of the vein.
On the property is situated the assay office, a 10-stamp mill equipped with a complete hoisting apparatus, [unclear text: Embrey] belt concentrator, etc. [et cetera] The mill is driven by a 26-ft. [foot] overshot wheel by water from the Hand canal. This water is returned to the canal before it reaches the Hand Mine, the next point where it is used, by a shunt canal 2 miles long.
More systematic and deeper (from the surface) underground work has been done on this vein than on any in the neighborhood.
Mr. Frank Moore, of this place, whose father worked the Lawrence vein from surface to water level, says that "more money was made from the 5-stamp mill on that property than on any 20-stamp mill in the district." Prof. [Professor] Torrey, of
Page: 55 [view image]
the U.S. Mint in Washington, who made a test during Col. [Colonel] Hand's lifetime of the different veins here, says in his report that the vein carries 10 per cent [percent]. of sulphurets [sulfurets]. It is certainly one of the most persistent veins in the region, or, I should say, it has been struck in more places and for a greater distance.
In addition to this vein there is a soft belt saprolite carrying gold which can be worked by the hydraulic process. The main proposition, however, is an underground one, as the vein passes very quickly from the surface and hence will require systematic underground work.The Hand Mine.
This property is situated 1 mile east of Dahlonega, on the Yahoola river. In territory it comprises 2 1/3 40-acre lots (see map). Lot No. [Number] 999 is practically virgin ground, while lot 1,032 has been only partially prospected. The topography is best described as "broken." The Hand canal delivers the water at a point on lot 1,031 233 ft. [feet] above the mill. The canal at present can carry 183 inches of water, which under this head represents 92 H. P. [horsepower] Besides this power a dam across Yahoola river on lot 1,052 diverts the water and by means of a canal furnishes all necessary power for the Hand and Yahoola mills, aggregating 35 stamps of 450 pounds each.
The ore bodies on this property are enormous, continuous and very even in tenor. The Knight vein is 20 ft. [feet] thick and the ore will average $6.00 per ton. The Antonia vein is 30 ft. [feet] thick (wall to wall) and is of the same value as the Knight. To show the quantity of ore on the property I will state the notes of a tunnel (Antonia) driven from the Knight cut to intersect the Antonia vein.
The tunnel started 18 ft. [feet] northwest of the Knight cut, its course being approximately northwest.
At mouth of the tunnel was a 10-ft. [foot] vein.
At 23 ½ ft. [feet] from mouth of tunnel was a 6-ft. [foot] vein.
At 57 ½ ft. [feet] from mouth of tunnel was a 8 ½ ft. [foot] vein.
At 83 ft. [feet] from mouth of tunnel was a 20 ft. [foot] vein.
Page: 56 [view image]
The experience in this tunnel has simply been borne out by the experience later, viz. [videlicet], that the whole property is one mass of ore.
The property has been worked continuously for the past 30 years, but the ground has been only scratched. I do not think that a greater depth from the surface than 100 ft. [feet] has been reached on the property.
The property is now in shape for systematic and scientific mining, as the surface has been removed, exposing the hard veins. The Knight and Antonia veins are now in hard formation with definite walls. They are heavily sulphuretted [sulfuretted] with ordinary pyrite, although not down as yet to water level, hence the concentrates will be amenable to cyanidation or chlorination. These ores yield from $2.50 to $3.00 on the plates and the remainder is lost, no attempt being made to concentrate. The ore presents no impediment to concentration.
The system of veins may be said to be lenticular. It has invariably been my experience here that the veins widen with depth. The Knight vein to-day [today] can be traced from a 2-ft. [foot] vein at the surface to the present 20-ft. [foot] vein at the depth of 60 ft. [feet]
The Company owns 2/3 of a mile along the strike of this vein, and it has been tested for nearly half a mile. It, as I before stated, holds its size and values over the entire distance. What I have said of the Knight vein -- I take it as a type, as I know more about it continuously than any other vein in the property -- is true of the other veins. I will venture to assert that if a person start at the northwest corner of the mill with a tunnel driven northwest (across the strike of veins) he will encounter good ore appreciable size in every 20-ft. [foot] drive. In short, I believe the Hand property to be simply a system of veins of pay ore, striking northeast and southwest and dipping to the east.
The facilities for working are the very best. A tunnel driven across the strike (with a course of N.W. [northwest]) will tap all of the veins with a depth sufficient to give stopes of 60 to 150 ft. [foot] length. The Knight vein is 118 ft. [feet] above the mill, the Antonia 150 ft. [feet], and the veins back of the Antonia (N.W. [northwest])
Page: 57 [view image]
are still higher above the mill. The tunnel is the logical plan of development, as it affords drainage, ventilation, gravity for haulage and ample stoping ground to supply a large mill for a year at the very least without one foot of sinking being necessary.
I would advise a large mill, preferably stamps, with amalgamation, followed by concentration on Wilfley tables. The concentrates are to be chlorinated by the Thies process or barrel chlorination. I will remark in passing that this process has been successfully tried on Knight ore with a very high degree of extraction.
To give an example of the ore bodies here and the state of development, I will say that last year the Company sluiced its ore some 1,500 ft. [feet] to the mill. About February 1, '98, an entirely new ore body, the existence of which had not been expected, only 300 ft. [feet] from the mill, was opened up, and it is on this same ore body that they are now at work.
There is on the property a 20-stamp mill and three workmen's cabins.
To show what I think the property should yield, I will figure all on a basis of a 100-stamp plant treating 200 tons a day.
Foreman $2 00 150 miners 150 00 10 trammers 8 00 Mill foreman 1 50 8 mill hands 6 40 Incidentals 16 79 Total daily expense $184 69
Two hundred tons of ore at $6.00 per ton equals $1,200,00, less 10 per cent [percent]. (loss in milling), gives $1,080.00 per day.
310 working days in the year give $334,800 00 Expenses of operating 57,253 90 Net profit per annum $277,546 10
Page: 58 [view image]The Yahoola Mine.
This property, which is a twin sister of the Hand property, as it lies adjacent to the Hand, occupies three 40-acre lots along the strike of the belt of the veins.
The Yahoola property contains a continuation of the Hand veins, with the addition of two high grade veins which have not as yet been struck on the Hand property, but which I fully believe are there. I refer to the McAfee vein and the Benning vein across the Yahoola river on lot 1,053.
The source of power, for both mining and milling, is the same on this property as on the Hand, the reservoir on lot 1,031 and the Yahoola river respectively. Hence the question of power for the future is practically the same for both mines, with the exception that the Yahoola property owns an additional 80 H. P. [horsepower] from the dam at the Mary Henry mill.
The logical development of this property is also by tunnels driven across the strike of the veins, but the stopes will not be so long as at the Hand.
The McAfee vein is about 18 feet thick (wall to wall) of $15.00 ore. The vein has only lately been uncovered. It was worked down to sulphurets [sulfurets] some 15 years ago, the ore was milled on a primitive 4-stamp wood mill. Mr. McAfee tells me that he got $10.00 per ton from every ton of ore milled. When they were well down into the ore body a large slide occurred and filled up their cut and they abandoned it. Today I finished some assays on this ore. We selected a piece of ore weighing perhaps 100 lbs. [pounds] as a specimen for exhibition. It was heavily sulphuretted [sulfuretted]. The crude ore assayed $119.60 and the concentrates $407.00. I do not want to be understood as saying that this represents the average value of the vein, but I think this an approximate figure for a rich 2-foot streak in a vein. Immediately under the McAfee vein is a small vein that assays $19.60 to $25.20.
The Benning vein of 18 feet thickness (wall to wall) will average from $10.00 to $15.00 per ton. This vein is heavily sulphuretted [sulfuretted], not however with the usual pyrite but with

Page: 61 [view image]
chalcopyrites (copper pyrites) which, however, is entirely amenable to chlorination. This vein is hard and very much contorted. A mill, if properly located, should be within the reach of the Knight, McAfee and Benning veins I think such a point is to be found below the Mary Henry dam and above the Yahoola dam, possibly below it. The surface has been sluiced off this property, exposing the veins similar to the Hand property, with the exception perhaps that not quite so large an area has been hydrauliced. This property is also one mass of ore, and requires a larger capacity mill, followed by concentration subsequent to amalgamation. I believe the Yahoola to be as good if not better than the Hand. The known thickness of its veins will aggregate 60 feet.The Findley Mine.
Including the two Boyd lots this property includes 200 acres of what is known as the black belt. The property is supplied in the way of power by the Yahoola river, which is estimated at 60 H. P. [horsepower], also a shunt canal from the main Hand canal. This canal water is delivered to the mine at a head of 283 feet. This canal (Findley) is capable of carrying 250 inches of water. The ore body here, I claim to be the largest in Georgia. The showing of ore is enormous. This whole belt in the big cut seems to be composed of innumerable arms of ore separated by parting of what I believe to be quartzose chloxite. These arms, however, come together or unite in the bottom of the big cut (70 feet vertically below the surface) and form a vein. The ore body on the northerly trend, above the mill, is vein-like in form. The ore body above the mill alone will furnish ore for a very large mill for years to come. The approximate tonnage in this ore body will be, assuming 20 cubic feet to the ton, equals 750,000 tons.
I will also mention the "Findley shute." This has an area of ore several inches in diameter that has been worked down about 350 feet. It is in the foot wall of the ore body exposed in the big cut. From this shute alone about $275,000.00
Page: 62 [view image]
have been taken. The gold is found in pockets and and [and] these pockets occur about every 60 feet.
The Evans vein lying across the Yahoola river from the mill is a high grade vein ($10.00 to $15.00) and is about 4 feet in thickness. It has been developed from the river to the river.
The question of treatment of this Findley ore body demands a mill of large capacity, say 200 to 250 tons a day.
The ore can be taken to the mill by gravity as it dips toward the mill, at an angle of about 70 degrees. This ore should be mined and carried to the mill for 50 c. [cents] per ton and should be milled for 25 c. [cents], making the total cost of treatment 75 c. [cents]
The two Boyd lots contain only virgin ground and from the surface panning, I think they contain some good ore bodies. Two years ago some men were permitted to haul the surface dirt to the Lockhart mill (3/4 of a mile) and they made good wages for so doing. The Findley property is well timbered with oak, chestnut and pine.
There is a 40-stamp mill on the property in excellent repair, and another piece of machinery which is a novelty, I refer to the pump. It is a Duplex water motor, made by Filer & Stowell, of Milwaukee; it is the only machine of its kind in existence. It operates, from the canal water, under a head of 283 feet and lifts 176,000 cubic feet of water to the vertical height of 435 feet daily.
There are two large shanties on the property for the workmen, located across the Yahoola from the mill.Barlow Mine.
This property, located in the 12th District, contains 710 acres along the strike of the Barlow belt. The question of power is solved by the Hand canal. The present Barlow mill is operated from this canal under a head of 135 ½ ft. [feet] The old Barlow mill is about 200 ft. [feet] below the canal, hence this head is available.
The main part of my report on this mine will necessarily be a matter of history. The old Barlow mill, 40 stamps, has
Page: 63 [view image]
the reputation of having made more gold than any mill or mine in this district. As to the amount it produced, this can best be illustrated by the fact that Col. [Colonel] N. H. Hand was sued for $166,000.00 as the 1/10 royalty due the heirs of an estate. This would make the total production of the min [mine] $1,660,000.00. The time occupied was 8 years. They worked on a soft belt which is simply the saprolite of Dr. Becker; this saprolite was soft enough to be cut by a giant, hence its name.
In the Haney belt above the Barlow mill are 5 shutes within a distance of 30 ft. [feet] along the strike of the vein or belt. These shutes are exceedingly rich. I have seen about 100 dwts. [pennyweights] of gold come from one panful (3 lbs. [pounds]) of ore. At this rate the ore would be $65,000.00 per ton. The shute on which the most of the work has been done is 2 in. [inches] thick by 2 ½ ft. [feet] along the strike of the belt.
There is an alleged sequence of veins from the Lawrence vein to Doghead vein, going in a southeasterly direction, which, if true, makes the property much more valuable. The veins are all high grade and vary in size from 1 to 5 ft. [feet] I have seen none of these veins, only the old inclines or shafts, as the case may be hence I say nothing about them.
There are on the property 2 stamp mills of 10 stamps each. In the Barlow mill is an engine and boiler of unknown horse-power [horsepower], presumably 60 H. P. [horsepower] or 70 H. P. [horsepower], besides a great deal of machinery in the order of grinding pans, etc. [et cetera] There are about 10 houses on the property for the workmen.Undeveloped Mining Lands
Besides the property described, the Company owns a great deal of undeveloped lands lying in the heart of the ore belt. These properties, I should say some of them, have a good reputation among the miners in this vicinity.Climatic Conditions, Supplies, Labor, Etc. [et cetera]
I find here that the climate is very even. In winter cold weather does not interfere wth [with] milling more than 5 days in the year.
Page: 64 [view image]
Supplies of all kinds can be obtained here at the usua. [usual] price in Gainesville, Ga. [Georgia], with 30 cents per 100 lbs. [pounds] added for freight. There is a Company Store, which should yield $500.00 net per month to a company working 100 hands.
The working day is composed of two shifts of 12 hours each. The following will give an idea of the cheapness of labor:
Shift bosses $1.25 per day. Underground miners 1.00 per day. Surface miners 80 per day. Truckers 45 c. [cents] to 60 c. [cents] per day. Mill hands 90 c. [cents] per day. Carpenters $1.50 to $2.00 per day. Blacksmiths 1.00 per day. 4-horse wagon, team and teamster 4.00 per day.
There is an abundance of timber here, pine, oak and chestnut predominating. The number of saw-mills [sawmills] and the quantity of timber here make lumber very cheap.
A partial inventory of machinery that does not come under the head of fixtures is as follows: One 120 H. P. [horsepower] engine and boiler.
One 60 H. P. [horsepower] engine and boiler.
One 20 H. P. [horsepower] engine and boiler (portable).
Three 40 H. P. [horsepower] boilers.
One high pressure Leffel water-wheel [water wheel].
One hydraulic ram.
One steam pump.
Two Rumsey pumps.
Two levels complete with rods for leveling.
About 4,000 feet of giant pipe.
