That as a rule rewa1ds from this labor will be at best modest and often nil is demonstrated by the history of any goldmining camp, The idea that the gold deposits of Georgia are largely undeveloped and that many rich ore bodies lie buried in the gold belt awaiting intelligent prospecting and development has no basis in fact. Rich deposits of gold which handsomely reward the efforts of those fortunate enough to uncover them are very un. common in any mining district.

Among miners in Georgia the term is generally restricted to the weathered portion of the lodes. It is important to note that the distinction be- tween the saprolite and lode deposits rests on the physical condition of the rock and is not a primary geologic feature. In other words, that portion of the lode which has been exposed to the physical and chemical processes of weathering (hydration, etc.) forms the saprolite zone. This zone passes downward into the unaltered, "hard rock" portion of the lode and has gradually be- come enriched by the mechanical concen- tration of gold during the slow breaking down of the lode in the process of weath- ering. As in the placer deposits, the richer portions of saprolites lie next to the un- altered bedrock. However, the fine gold may be more thoroughly disseminated through the deposit. Saprolite deposits are eharacteristic of the Piedmont region of the southern Appalachians because the geo logic hi story of this region has been favorable to very slow Figure 3 .-VJew of lode exposed in Black shaft of Cherokee mine in Cherokee county.

Too much emphasis should not be placed upon the past history of a mine. The richer ore may have beeu mined out. The character of the remaining ore is the all-important question. No mine is truly on a paying basis until sufficient exploratory work has proved the presence of ore bodies of sufficient size and value to guarantee a return of the capital investment, plus costs of operation, plus a reasonable margin of profit. Until that is established the mine is merely a prospect, subject to all the haz- who is interested. The "free gold," or that which is not intimately associated with th sulphides (iron pyrite, etc.), has been largely mined in the past because the simpler metallurgy and cheaper mining of the oxidized free-milling ore allow on the average a profit from a lower grade of material than can be worked in the sulphide zone. II. The productive areas of this county contain narrow, elongated lodes, trending northeast. The structure of the enclosing formations has controlled to a notable degree the development and mineralization of the gold-bearing lodes. It is believed that an understanding of these structural features will materially aid in prospecting and developing the ore bodies, and for this reason they have been studied in some detail. Contrary to common belief, the individual ards attendant on the lack of knowledge Geologic Features lodes do not extend for long distances. They as to what lies below.

Greater widths means eliminate them. In addition to geologic data, sampling and assaying of the explored ore bodies is important. Gold veins, especially, show wide variations in value, even within a distance of a few feet, and the mean or average of the aRsayed samples will generally be much 100 years. Pits, trenches, old tunnels and shafts, open cuts, and abandoned placers are found in all the areas showing mineralization. It is doubtful if any large area exists that can be regarded as virgin territory for prospecting. Parts of the gold belt where there is no such evidence of past are exceptional. Some of the lodes lie end to end, with barren areas between, and this arrangement probably explains the local belief that the lodes extend for many miles without a break. At any point in the gold belt ~everal lodes may be developed parallel to one another. They lie either roughly lower than the highest results obtained. Emphasizing th e highest as~ays obtained in sampling gives an optimistic picture of the property's value which is not warranted. Selective or haphazard sampling of the ore body is equally worthless. Proper sampling requires the utmost caution and skill and is very often an expensive procedure, costing prospecting were for some reason passed over as unfavorable. Exceptions to this would be lands owned by individuals or families who have not permitted prospecting on their property by outsiders. Certain partR of the gold belt have been favored by extensive and locally intense mineralization. It is in these areas that parallel to the belt or-as on Findley Ridge, for example-at an agle to the belt (fig. 4). The position of the lodes is as a rule closely related to the cleavage, grain, or schistosity of the enclosing rock. Excepttions occur, but commonly the lodes trend northeast and dip or slope southeast with the cleavage of the formations. hundreds or even several thousand dollars, most of the mining has been done and that These lodes are termed "veins" by the If the deposit sampled is of fairly large present activities and future possibilities prospectors and miners, but the true veins size. It is obvious that until sufficient exploration has been carried on to open up of production largely lie. The recent sur- consist of the many small irregular-shaped a considerable portion of the vein or lode, che most accurate sampling gives only a partial picture of the true value of the ore body. A detailed mine map showing the exact locality of each sample in the shafts, ~rosscuts, drifts, etc., and an assay sheet co accompany this map are absolutely es- 3ential. The question of the depth to which profit.tble ore bodies extend in the gold belt of Georgia is still an open one. The answer to thi;; question lies largely in what future underground development will disclose. Present knowledge does not indicate extensive and rich ore bodies in the deeper portions of the lodes. The known facts show that in areas where conditions of mineralization have been favorable, ore bodies that may be profitably mined lie below the water table in the sulphide zone but that only very locally do they contain small rich pockets of gold. Mining cannot be carried on at a profit everywhere in the Georgia gold belt. There are large areas which show very little or no mineralization. In other areas the gold, though widely distributed, is present in so small an amount that mining operations of any type cannot be profitable, rbgardless of Figure 5.

A small amount of stoping has been done along the richer parts of the ore body, In addition to this work, another monly, the higher tenor tends to be concentrated in localized ore bodies, which vary in shape according to the local structural features of the rock. The deep-lying granitic intrusions, now well exposed over the region, probably formed the source of the mineralizing solutions, which found a more ready passage where such features as rolls in the schistosity, shear planes, joint planes or fissures, or more open cleavage were present. Technical details relative to the mineralization will be considered more fully in a forthcoming report by the United States Geological Survey. The point emphasized here is that in the area of mineralization the structural features are significant. As an illustration of this point, it is common knowledge among the miners doing under- gold in the past, the placer and saprolite deposits are worked from time to time by a small group. Most of these miners are local farmers or landowners who operate with pick and shovel and sluice box, discontinuing their gold mining when the water gets too low, when farm work demands their attention, or when more lucrative labor can be obtained. Few of these miners average more than a modest daily wage. An occasional richer find may create much local excitement. There are several counties where mining operations are of sufficient magnitude to merit more detailed descriptions. Some of these properties have afforded valuable data on the problem of Georgia gold deposits. shallow tunnel has been extended.

The mill consists of a jaw-c1usher, a 10-stamp Straum circular stamp-mill, amalgam pla.tes to recover the free gold, and a Wilfey table to recover the Bulphides, which are now being stored for later shipment to a smelter. All the o1e f1om the mine, lowgmde and 1ich shoots alike, will be t1eated in the mill. This property typically illustrates the characteristics of lode deposits described in a previous article. The highgrade ore represents the "lucky find" that now and then occurs in gold mining. One ground work in the gold belt that in many places the ore forms shoots or chimneys in the lodes. These ore shoots are in the form of ellipsoidal masses that average a few feet in cross section and rarely exceed 100 feet in length. They generally plunge or "rake" at fairly steep angles within the lode and to the northeast. The data in hand show that "rolls" (waves) in the schistose cleavage of the country rock have deter- mined the formation of such ore bodies. The reader can obtain a mental picture of this structural arrangement of an ore shoot by comparing the lode with its many small, irregular veins to a house roof sloping southeast. If the roof had large corrugations running at an angle down the slope and to the northeast, these corrugations would represent the rolls in the schistosity. The ore shoots lie with their long axes roughly parallel to these rolls or corrugations and at points along the length of the lode where struetural conditions have been more favorable for the localization of gold deposition.

Detailed testing of the placer ground before operations are started is strongly recommended. From the information furnished by properly distributed test pits and bore holes many valuable data can be obtained as to the distribution of the gold and the best method of working the deposit.

The ore is treated in a small ball mill. The place1 and saproLite deposits of the old Yo>kville mine, about two and a half miles east of Yo?kville, are now being prospected under the direction of M1.

McDuffie County McDuffie County has had several important mines in past years, but at present the only activity, aside from haphazard "gophering" by local farmers and landowners, is confined to the property of Mr. W. H. Fluker, about 12 miles northwest of Thomson, adjacent to the Little River. A quartz vein has been opened by a shallow shaft. The ore is treated in a small stamp mill. On the Fluker property and distributed over adjacent areas are several mines which have been producers in the past. These include the Columbia, Park, Hamilton, and Seminole or McGruder mines. All these properties have been abandoned for several years, some of them for many years, and any determination of their future possibili- ties would require careful examination of the old workings, which are now inaccessi- ble. The geologic .features and character of mineralization in McDuffie County are in o;enera! similar to those in other parts of the r;old belt, but this area shows a more pronounced development of the veins. The reader who is interested in further details should write to the State Geologist in Atlanta. Bulletins 4-A and 19 of the Georgia Geological Survey (now out of print but available at many public libra- ries) give descriptions of all the properties of any past importance in the gold belt.
