MONTREAL: PRINTED AT THE OFFICE OF THE MONTREAL PILOT. 1848. v< I i » 1 « '¥!-gMt.«Mli u lre time than I could possibly devote to it; but, with the partial exploration made, the discoveries are : — 1st. — At a point, say two and a half miles, from the shore, and half a mile from the east line, in the side of a hill, and about three hundred feet from its base, a vein vein of quartz is exposed to view about 3 feet wide, and car- rying some little portion of yellow copper pyrites. A little west of this point is a very promising side vein, bearing cop- per, about 1 foot wide, falling in with it ; and taking into consideration that the rock is the true metalliferous stratum of the district — that copper is interspersed in the rock sur- rounding the vein — that this side vein bears very rich spot? of pyritous copper — that the quartz of which the vein is com- posed principally is the true gangue of the copper — bearing veins of this district ; — all these facts would induce me to believe that it is well worthy of some trial in mining, and might probably be of great importance ; by sinking on it a few feet would prove if it would improve in descending, and if so, it would establish the fact of the copper having a down- ward tendency, and consequently the probability ot its being a lasting workable vein. 2nd. — North from this before named point, say |ths of a mile, in a dyke of trap, are three veins of quartz within the space of about 40 feet, each of those veins ranging from 1 to 2 feet wide, and of a truly metalliferous character ; but at this point showing no copper ; yet I should think the Com- pany would do well to open them for the purpose of testing them. 3rd. — ^Nearly due east from No. 2 point, and nearly the east line of the location in a small stream is another vein of quartz, a little more aluminous than either of the other veins I.

All these veins should be cautiously and carefully tested by mining ; but no considerable outlay should be made with- out improvement was perceptible in the veins as you de- scended ; and if such improvement should take place, it would clearly define your line of future operations. I recom- r^end this because many a true and valuable vein which, at the surface, was composed of the proper metalliferous gangue as these appear to have been, have, in descending, become immensely valuable. 4th. — Near the east line of the location, and say 3^ miles from the Lake, appears a junction of quartzose rock and the trap formation. At this point a number of veins, varying from 2 feet wide to 6 inches, cover a space of at least 20 feet ; and along the whole of this surface the pyritous copper appears in rich abundance, and amply justifying any recom- mendation I might give fur future mining operations, promis- ing abundant success. Break it at whatever point, and I found it would yield similar specimens to those which accompany. At the foot of the rock lie masses of veinstone of considerable sizes, rich in copper. While I would be extremely cautious in my recommenda- tions, it would not become me to conceal the impression which rested on my mind previous to my examination of this property, and which opinion is now fully confirmed, that Keating's vein on the Bruce Mines should cross this location near this point, and that this is a continuation of the same vein. If so, what the value of this vein is cannot be fiilly imagined ; and there is no longer uncertainty or speculation in the mining of it, but a return of profit that will be yielded and increased in proportion as any given number of miners may be properly emoloyed. If it is not Keating's vein, yet still such are the indications on the surface — such the value of the stuff broken out of the vein — such the probabilities of its being very productive at the junction of the strata, that any intelligent miner seeing it, would pronounce that here was a field for mining investment, and a certainty of return suflicient to satisfy any reasonable expectations or wishes. 5th. — Going west from this point, I again found large masses of vein stone bearing copper, and in all probability in the direction of the last named discovery. The vein is aboul 3 feet wide, intersected by another about 1 foot wide. In addition to the yellow copper is the carbonate of copper, and showing every indication of being exceedingly valuable : this probably is a continuance of the large vein. ( i 10 Taking into considoration tlio appearances of the veins, n-.ul tiie direction of the true metalliterous deposits of thedis- trict, I cannot hesitate in recommending thia as the line for future mining operations in preference to any other on this property that has yet come under my notice. With respect to the mode of egress and ingress to and from the Lake, the north-west side of the h)cafion is bounded by a large Lake about 4 miles long and :| of a mile wide, which empties itself into Portlock harbour, thus affording great facilities for the transporting necessary supplies and the mineral by water carriage, with a short distance by road on a very level and lirm piece of land. The streams of water are few, and but small, yet suffi- ciently large for washing and separating the ores that may be raised i)y mining. Some parts of the land are covered by largo pine and birch trees, and are well adapted for farming purposes, thus giving the opportunity to the Company of raising those vege- ttibles, Ace, which might be necessary for supplying the laborers, instead of bringing these tilings from a distance, and incurring all the disadvantages connected with their trans- portation. The method proposed for working the veins numbered 4 and 5 should be commenced by sinking a shaft on the vein No. 4, and at the same time opening for a short distance from north to south, so as to ascertain the proper direction of the metalliferous deposite ; this opening to be merely on the surface of the rock, — the shaft to be continiieddown for about 15 fathoms, or as far as the free ciicuhition of air will per- mit, — then drifting on the course of the vein, and by sinking a second shaft, say about 40 to 50 fathoms distant from the first, and drifting towards it, so as to meet and mike a com- munication with the first shaft. By this means a free circu- lation of air will bo produced that wid enable you to resume the sinking yoiu* shafts and extend your drifts on either side, while it will also leave the back of the vein fairly tested and opened on, so that you may commence stopeing or breaking out the vein at a much less exiense, and giving all the ne- cessary information for your future operations. The number of men required will be G miners and 2 as- sistants for mining, and the necessary number of workmen that may be required for making roads and raising the neces- sary buildings. The method of preparing the ores for the market should be by careful selection of the richer portions, and then by crush- ing the poorer portions and washing the ores previous to smelting. 1 t ' the veins, 3 of thedis- the line for her on this to and from bounded by ■vide, which ding great es and the by road on 1, yet suffi- that may be pine and rposes, thus those vege- pplying the istance, and their trans- lumbered 4 on the vein istance from iction of the sroly on the ,vn for about lir will per- 1 by sinking mt from the Hike a com- n free circu- )u to resume either side, y tested and or breaking , all the ne- •s and 2 as- of workmen 13ih August, 1817. J I h^ woods, diately on d equal to INICK, REPORT OF RICHARD KERNICK UPON THE LOCATION NOETH OF ECHO LAKE. TO THE TRUSTEES OF THE LAKE HURON SILVER AND COPPER MINING COMPANY. Gentlemen, — The location on the north side of Echo Lake, of which your property there consitsts, lies at the westward end of the lake, and is approached by a river from Lake George, dis- tant about 3 miles. At the entrance of Echo Lake, a visitor will be immediately struck with the advantage of these waters to the Company in furthering the mining operations on the pro- perty. The hills rise from its waters to a very great height, and thus in the working of the veins that may be found, preclude the necessity of water c'larges for years to come. The altitude of these hills has been stated at not less than 700 feet from the level of the water ; and when the great expense necessarily attendant on the dr-iinage of water from a mine is taken into account, the value of this property becomes proporlionably greater by its exemption from such expense. Thus, then, you have water transportation for your supplies and mineral, and drainage for your water. I visit, d this location, for the first time, for the purpose of taking a cursory survey of the property previous to a systematic exploration, in company with tlie Hon. H. H. Killaly. It was then thought best to work upon a vein which was very distinctly defined on the face of a hill and at a point about 400 feet above the level of the water, and where the vein was about 5 to 6 feet wide. On each side of the vein the gangue was composed of a very fine quartz, aflbrding every indication of its being a true metalliferous vein. Along its face was seen the bisiliceie of copper, and the blue and green corbonates of copper ; on break- ing it, the yellow copper pyrites was found to be universally dif- fused, and some very fine peacock colored and gray ore. Although this vein would not be pronounced to be vtry richf ,1 14 yet it had a very promising character, and the copper evidently tended downwards, ao some very rich specimena were taken from the lowest point near the d briss. At my next visit, J. R. Livingston, Esq , discovered in the same hill, a little west of the above named vein, another vein about 3 feet wide, of fine quartz, and among the debris large quantities of veinstone was observed, in which copper was abundantly difl'used. This vein is clearly defined — the walls are very distinct^ the quartz highly metalliferous — the copper of a beautiful bright yellow color, in many instances showing the richly variegated copper ore associated with it ; and then its verging in its course towards the before-mentioned vein, proves that if no other point were discovered on this property to warrant mining operations, these are amply sut)icient. The best method of operating successfully on these veins "Would be to trace them to the lowest possible depth, and commence a drift into the hill ; thus openmg along on their course, and leaving a high hack of ground to stope in the most valuable parts of the vein. Noshatts would be needed for a longdistance, as by two drifts, one above the other, at stated distances, say 60 to 70 feet, by communicating these drifts one with the other, you will ventilate your mines for several years. Having narrowly explored the adjoining location on the south side of the lake, and finding there a great number of veins of the most prominent character, and rich in copper, crossing the mountains, and evidently directing their course towards this location, and as the mountains of this locality are a continuance of the trap range, and are truly metalliter- ous, I cannot conceive but that this will prove very valuable. I cannot close these remarks without adding that the opera- tions which have been carried on under the direction of the Hon. H. H. Killaly, on the adjoining property, south, and which are every day proving the increased value of that pro- perty as a mineral district, must have a beneficial result on this property, as it will be a key as it were to guide you in your further researches, and must greatly facilitate your further exploration and point out the most desirable spots to be most careful and scrutinizing in the examination of; so that nothing may be overlooked. Mining speculations have been viewed by many individuals with feelings of distrust, and those persons have avoided them as they would the sure road to ruin ; others there are who enter into them with the idea of making a fortune almost instantly, and in their visionary fancies almost clutch the tempting gold. Each of these characters greatly err. 15 evidently ^ere taken red in the oilier vein ebrid large )l)per was distinct — beautiful the richly its verging roves that to warrant hese veina depth, and g on their ope in the be needed e other, at Lting these mines for ;ion on the number of 1 in copper, heir course this locality metalliler- •y valuable. 1 the opera- ction of the south, and of that pro- ial result on uide you in iilitate your il)le spots to n of ; so that jT individuals voided them ere ure who rtune almost t clutch the greatly err. Mining, if properly conducted in a mining district, cautiously and judiciously, will yield fair returns tor capital invested, and in many instances immense profits. To those persons who, in old mining districts, have invested capital for the purpose of mining, it is well known that the average return of any given number of these mines, so far from deterring them from embarking capital in these undertakings,only holds out strong inducements to investment. And if in those districts they are safe undertakings, why should they not be so here ? They have the advantage of older experience and cheaper labour — you of shallower mines, scarcely any expense of machinery, cheap timber, and much richer veins, the veins yielding a higher per centage ofcopper. The expense of heavy machinery in the older districts, from the great depth of the mines, and the immense quantity of water and stuff they have to draw out, can be fully imagined but by those who are now or have been engaged in those works. Much depends on the proper method of working the veins. Subject to bad or extravagant management, many mines which, under a different state of things, would have yielded a fair if not a very large interest upon the capital invested, have too often been profitless and losing cencerns, and have been needlessly suspended or prematutely closed in consequence of general expensive management ; but where due caution is used in the selection of the vein, and a just consideration is given to the proper mining and practical economy, it is certain that so far from being dangerous and speculative concerns, they are highly productive and im- mensely profital)le : and if they are at all productive, the profits will be yearly increased, and will enable those using due caution and activity confidently to calculate upon a return of original capital without any interruption of the most effec- tive and full operation. Ill conclusion, gentlemen, I beg leave to congratulate you on the judicious selection of your property, and wish you every prosperity in your spirited udertakings. All of which is respectfully submitted. I have the honor to be. Gentlemen, Your very obedient servant, (Signed) RICHARD KERNICK HiNCKS Location, Lake Huron, > 13th August, 1847. y REPORT OF FORREST SHEPHERD •I ' •»ii ON THE HINCKS LOCATIOIf. TO THE TRUSTEES OF THE LAKE HURON SILVER AND COPPER MINING COMPANY. Gentlemen, — Having been employed to visit and make an economic geological examination of your property known as the Hincks Location, situated near the entrance ofPortlock Harbor, on the North Shore of Lake Huron, I beg leave to lay before you the following as the result of my examination. REPORT. The Hincks Location, as established by the Government Surveyor, is adjoining the Copj)er Bay Location, and only two miles westward of the location embracing the Bruce Mines already celehrated as the most remarkable discovery of copper ore hitherto made in North America. The rock at the Bruce Mines is hornblende or sienitic trap. The same rock is found to occupy a large part of the Hincks Location. 1 he veins at the Bruce Mines are of quartz, and vary in demensions from two feet ap to fifteen feet, and in some places reach even thirty feet in thickness. The genend direc- tion of the Bruce veins is nearly north -west and south-east; and if they extend inland, of which there is very strong pro* bability Horn the indications which I met with, they will in that direction run entirely through the Hincks Location^ a little northward of its centre, as may be seen by the accom- panying map. On or near the western border of the Hincks Location the sienitic rock of the Bruce Mines makes its appearance witb copper bearing veins which, as I remarked above, renders the probability very strong, that the Bruce veins extend entirely through theHmcks tract, although covered with a deep dilu- vium, the location thus affording excellent soil fur farming pur- ()08es in addition to its mineral wealth. iM ! wy ER AND make an wn as the k Harbor, ay before jvernment only two jce Mines of copper ?nitic trap, be Hi neks |uartz, and nd HI some leral diiec- sDuUi-east ; trong prO' ley will in jOcatioTii a ihe accom- location the » ranee with renders the !nd entirely Jeep dilii" farming pur- 17 But whetlier these veins cross the location as supposed or not, is not a matter of innmediate importance, tor 1 have dis^ covered others on this location which yield fine copper ore on the fiist blow of the hammer and pick, and which in my opinion are sufficient for the successful operations of any com- pany for many years to come. I shall first speak of Uie situation and extent of the location, its natural advantages, &c., and subsequently of its capabilities for mining j^ijrposes. This location is most favorably situated on the northern shore of the broad and deep channel, which extends some eight or ten miles up from the open waters of Lake Huron and sepa- rates the main land from the large Island cf St. Jo:»eph. (Sea Map.) It has a front of two miles upon the water by five miles inlani), giving an area of six thousand four hundred acres. St. Joi^eph's Channel is here from three to four miles wide, with a depth of water varying from twenty to sixty feet. On the south east part of the location is an excellent harbour admirably pro- tected by several small islands, while Portlock Harbor, on?". r\ the best in the world, lies near and parallel with the wester a boundry of the location for at least two miles and a half. H« a vessels of the largest class may find easy ingress and egress, as well as the safest anchorage, and perfect security against all storms. On the northern part of the location are situated two lakes, which by means of rivers flowing from them into Portlock Harbor/render the northern section of the location easily acces- sible by boats und canoes. Near the outlet of these lakes, one or two mill seats may probably be obtained. There are several other streams of minor importance upon the tract. The surface of the tract is moderately hilly and undu- lating, consisting of a succession of cones and ridges rising from the lake level to the height of three hundred feet or more. Nearly the whole tract is either fit for tillage or pasture. The lower grounds with littlo labor may be made to yield large harvests of hay for the winter, while near the central portions of the tract will be found from one to two thousand acres of fine arable land well adapted to the growing of grains and difierent kinds of esculent roots. There is on the location an abundance of timber consisting chiefly of white or red pine, cedar, elm, white birch, poplar, spruce, tamarack, fir, maple, ash, oak, and iron wood, &c. Good fishing grounds exist on the shores of the location. The climate is remarkably healthy and the winters are con- sidered much milder there than at Montreal. The prevailing rock on the locatioo, as I have before men- Mi* I' ' i; ij I ' I Fl 18 tioned, in an apparently stratified syeitite enclosing large veini of quartz in which are found both the yellow pyritorm and the vitreons or grny sulphiirei of copper.

Pro- id respect. I be com- the centre ^s westerly al locationy Of this, I For to say th- western, of ihe very tending en* 19 tirely tlirough the Hincks Location, tliere is on the northern haU of it about four miles inland upon the eastern line, a large vein of quartz measuring nine feet or more in thickness. This vein is nearly vertical, and runs nearly east and west, as seen in the map. It has all the strong characteristics of the Bruce veinSf and probably shows quite as well as those veins did before there was any excavation. It yields readily both yellow and gray copycr on the Jirst blow of the hammer and pichy and has been traced by cross cuts on the location for nearly half a mile. This vein alone, independent of all others, I am conjident, will be sufficient for the successful operations of a well organized Mining Company for many years. To this I would, therefore, direct your attention. The ore from this vein is chiefly the yellow copper ore, which is a double sulphuret of copper and iron. It contains : — 34 8 sulphur, 34.8 copper, 30.4 iron. If crushed and washed from its adhering veinstone and foreign matter, and properly smelted, it will yield eight parts of copper to every twenty-three parts of ore, or, in round numbers, thirty- three per cent. If the ore is imperlectly dressed, the yield will be less accordingly. It is for such ore mainly that the Messrs. Williams, Foster & Co. and Crown Company have paid nearly four hundred thousand pounds sterling the past year, and the Messrs. Vivian & Sons about three hundred thousand pounds. It is, in fact, the ore on which the g.-eateat dependence is placed in Cornwall, The purple or " horseflesh," and also the vitreons or gray sulphuret, are to be found in this highly promising vein. Wherever they come in, the richness of the ore will be much increased ; the purple yielding from fifty to sixty, and the gray from seventy to eight)-^, per cent. Veins are seldom worked out in depth. Upwards of five thousand tons of ore have been raised the past year at the Treasaurean Mine, Cornwall, and a good portion of it from a depth of eighteen hundred feet j also about twelve thousand tons at the United Mines, and much of it from a depth of fifteen hundred feet. More than three hundred and eighty thousand dollars have been paid for the ore thus raised from the above two mines the last year, ending July 1st, 1847. (See Gryll's Annual Mining Sheet.) It is difficult for one without experience to imagine the disadvantages at which mining is carried on in Cornwall at such depths. The timber for preventing the vein walls from falling, &c., comes from Nor- way at a cost of sixteen pence, or more than thirty cents,per foot. This must all be taken down to the working level to guard r 20 against tho extreme superincumbent prewsure. It in then ne- cessary to have a blacksmith's shop far down under ground to facilitate in sharpening the .oola of the miners for excavating in the hard rock : a supply of coal must be taken down for the smith's fire. The combustion of the coal generates an abund- ance of carbonic acid gas, which, with the smoke of gunpowder in blasting, greatly vitiates the atmosphere, so that the average age of the miner is shortened to about thirty years, and the aver- age time of his working in the mines to 16 years. When we add to this the extreme heat of the air and water in mines at Buch great depths, frequently rising to 100 degrees of the ther- mometer, and the indescribable hard labor in descending and ascending the ladders, even below the reach of the " man en- gine," to say nothing of the increased hazard of human life, what would the miner not give to find the rich resources of these great depths immediately on the surface, as may be seen at the Bruce Mines and Hincks Location on the north shore of Lake Huron ?

REPORT OF FORREST SHEPHERD UPON THE LOCATION NORTH OF ECHO LAKE. TO THE TRUSTEES OF THE LAKE HURON SILVER AND COPPER MINING COMPANY. Gentlemen, — In pursuance of my engagement with "you to visit, examine and report upon your mineral location, situated on the nortli side of Echo Lake, in the Lake Huron District, allow me to olTor, very n^spcciruUy, the following observations. Echo Lnke is only about three miles north-westward of Lake George, or about eight miles from Church's Steam-boat Landing, cr twenty-five miles from the Sault St. Mari6. It is a beautiful lake from four to five miles in length and one and a half to two miles in breadth. It is connected with Lake George by a river navigable for large barges, and which, with some little excavation, would probably serve for steam-boats. The water in the Lake is deep, and the adjoining hills rise abruptly from its shores to the height of 800 or 1000 feet. The whole tract, five miles in length, north of this Lake, ami of an average depth of two miles, containing ten superficial miles or 6,400 acres, was, I understand, granted in block by the Government to the original locatees, who divided it into two equal parts, each two and a half miles in length, from east to west. One of these parts, the western, is your property. It has an area of five superficial miles or 3,200 acres. The eastern portion, of the same location, is the property of the Echo Lake Company. As the north shore of the Lake forms, in part, the south side of your location, and as its western limit can be correctly ascertained by measuring two and a half miles from the western mark, by which the Government grant is decided, there can be no difficulty whatever in having the limits of your property definitely marked whenever it is considered desirable. Indeed I would have marked it myself, but from an anxiety to devote the whole of my time to the close exploration of the location, and more particularly as I found that to form a safe opinion of its 22 mineral resources, I was compelled, by the lie of the mountains, the direction of the veins and stratification, &c., to extend my examination generally over the whole tract, north of the Lake. Having done so, I considered it advisable not to confine myself in this report to a description of your property alone, but to give you the result of my examination generally, inasmuch, as independent of the many advantages and mineral indications which are apparent on your property, the existence of the veins and other favourable appearances in the portion eastward, and immediately adjoining it, of course tend strongly further to confirm the high estimate that my explorations have led me to form of the value of your property. The following, therefore, you will understand as a general description of the highly interesting and promising mineral tract, north of Echo Lake. But the portions of the descriptions which relate directly to your own property, will be obvious. Several streams water the tract, but Caribou River, the only one capable of supplying water power to any considerable extent, is on the eastern part of the location. It is a very permanent and valuable stream for propelling machinery. This river has a rapid fall for a quarter of a mile before it enters Echo Lake, and here it is that large quantities of red and while pine lumber may be expedi- tiously prepared for market by the aid of a sawmill to saw the numerous and lofty pines that grow upon the tract. If I am not mistaken in regard to the boundaries, no location in the country can vie with this in its supply of excellent pine timber. The east branch also of Carabon River affords a succession of mill seats, while, as may be seen by the map, it flows over several copper bearing veins. Upon this stream is a remarkable natural mill-dam, and flume about five feet wide and fifteen feet deep, cut as if by art through the centre of the dam, and all, both dam and flume, consisting of solid rock. In short every thing is here ready for the erection of a mill. Should mining be prosecuted on the banks of this stream, as it probably will be, tlie water power may be very advantage- ously employed in raising the ore and pumping out water in the same manner as is seen at Wheat Friendsliip, in Cornwall, performing as it were spontaneously the labor of an expensive Bteam-engine. Still higher up the stream, above the flume, are two small lakes which may serve as important reservoirs in dry seasons. In addition to the pine timber above mentioned, there is upon the location a heavy growth of maple, hemlock, spruce, birch, cedar, fir, larch, &c. Much of the soil on the location will be found fertile, especially along the vallies, where some farms of superior quality may be selected. 23 le mountains, to extend my of the Lake, on fine myself alone, but to nasmuch, as il indications e of the veins sastvvard, and jly further to ive led me to ig, therefore, )f the highly Echo Lake, e directly to treams water J of supplying ! eastern part uable stream lid fall for a here it is that r be expedi- ill to saw the ct.

A dense chloritic slate rock, in appearance approaching green stone, serves chiefly as a foundation. Upon this is seen a very com- pact and altertBd sand rock, over which lies another porphyritic or brecciated siate, and upon the latter a highly siliceous lime*, stone. The mineral veins are composed of quartz and ore of a later formation than the rocks. They cut through the differ- ent strata of the above rocks without distinction, are nearly vertical, and their course is generally a few degrees north of west and south of east. Some ten or twelve veins have been discovered on the location, all of which yield yellow copper ore. I have never seen in anyplace such a general distribution of this valuable ore. In some places, over the surface of many acres, it is diflicult to break a stone without finding copper. Such is the case along the blufFeastward of Carabon River. The vein stone, although chiefly quartz, is accompanied by ferrugineoua carbonate of lime, and also carbonate of iron, which are very favorable indications in the mines of Cornwall. Rich gossans are also found along the veins, an indication always acceptable to a practical miner. The above veins vary in thickness from one to four or five feet. They cut through indiscriminately every kind of rock upon the location ; and hence copper is seen in the slates, con- glomerates, sand stone, and lime stone, as well as the upheav- ing trap and sienite. In the hard sand stone, and very dense rocks, the veins are smaller in proportion as the rocks harden, and will therefore probably be less productive. Although there are traditional reports of silver having been found upon this location, I have no positive evidence of its existence here. If found, it will probably occur in cross courses, cutting the east and west copper lodes at right angles. Such cross courses exist in the bluff east of Carabon River, but have not yet been explored. Blue and green carbonates of copper make their appearance in some of the above men- tioned veins, but the yellow, or double sulphuret of copper is here as at the Bruce Mines, and in Cornwall the prevailing ore. Its composition is — 34.8. Copper, 34.8. Sulphur, 30.4. Iron, lOO.O. 5"P 24 Upwards of two hundred thousand tons of twenty-one cwts. each, principally of this description of ore, have been raised' in Cornwall and Wales the last year ; for which more than one million and a half pounds sterling have been paid j and from which more than twenty thousand tons of fine copper have been produced. (See Grylls's Mining Street, No. 16.) Only one vein (called " Peirce's Vein"), has been explored to any extent on the tract. It is situated towards the eastern side of the portion of the location belonging to the,iLake Huron Silver and Copper Mining Company, and is about 300 ft. above the lake, on the steep declivity of the mountain. It runs inland as seen upon the map, a few degrees north of west, dips to the north at an angle of 80 degrees, and is from two and a half to three feet in thickness. The vein stone is quartz filled through- out with a lai'ge amount of the double sulphuret of copper. Several tons of specimens have been already excavated from this vein, which are on their way to New York. They shew at once the quality of the ore, and its accompanying vein stone. Judging from surface appearances, this vein, by common con- sent, is allowed to stand in reputation " second only to the Bruce velna^ The exploration of another season, however, will better determine its true character, for as yet it is only slightly opened, and that upon the surface. This vein is in a porphyritic slate rock, and only one of five or six others, some of which are larger, all running parallel on the same hill side, and all bearing copper, with the extraordinary advantage of three hundred feet of spontaneous drainage. The veins on the east branch of Carabon River, are very similar to those above described. They measure from two and a half feet to four feet in thickness. The ore is the yellow copper, but the rock more chloritio, and of a lower givide in the geological series. For want of time, the only exploration of them has been to ascertain simply tliat they contain copper. Another vein about two feet in thickness, and composed almost entirely of rose-colored calcarious spar may be seen on the eastern extremity of the bluff, near the large river that flows into the east end of Echo Lake. The spar in this vein is of a highly promising character. Another interesting vein, showing a small amount of yellow copper, may be seen in the lime stone on Lime Stone Point. Many of the rich deposits of cop- per in Russia are connected with lime stone in like manner. This lime stone, especially where it is highly charged with iron, may be useful as Roman Cement, or hydraulic lime. The stone of the large hill north-west of the point, wiU probably burn and slack well for ordinary cement.

I can only add, in conclusion, that this location, from Its position, variety and very favorable surface indications, is to me one of peculiar interest. Years will elapse before it will probably be thoroughly explored, and fully appreciated. My sincere conviction is, that it is destined to hold a high rank among the choicest localities of this recently discovered but highly promising mineral region.
