 Tins ininc is situuhMl in Slierhrookt bounty, Canada 
 East Its close proximity to established smelting works, 
 and the railroad facilities, render the location eminently 
 favorable. It is about 4 miles from the well-known 
 Clarke and Ascot Mines, and occupying the same belt of 
 copper-bearing rock. 
 
 For the purposes of developing the resources of this 
 property, it is proposed to organize a corporation r.nder 
 the laws of Massachusetts, to be known as the " Hatley 
 Hill Mining Company." 
 
 The Company will be organized with a capital of two 
 hundred thousand dollars, divided into one hundred 
 thousand shares, twenty thousand dollars to be reserved 
 as a working capital, thus relieving stockholders from all 
 liability to assessment, and furnishing a sufficient fund 
 for the further developpient of the mine. 
 
 Reports on the present and prospective vaUie of this 
 property, made by gentlemen whose scientilic attain- 
 ments and extensive experience are an ample guarantee 
 for the reliability of their statements, are herewith sub- 
 mitted.

 The following ig the result of vxy examin.iiion of tjie 
 Htitley Tlill Mine, in Tlatlejr, C. E., \\vm\^\ in your com- 
 pany, Feb. 24, lcSG4. 
 
 The property consists of 100 acres, mostly of im- 
 proved hind, composing the eastern portion of Lot No. 27, 
 range 4, of JItitley. Ad.iacent to it, on the south, is the 
 property known as the Massawippi Mine, while both ou 
 the north and south sides of it, near the eastern ex- 
 tremity, are other mining locations, where trial pits have 
 been sunk with good success. The property is, there- 
 fore, so situated that iui])ortant discoveries made upon 
 iany of these adjacent mining chums will fdso increase 
 the vjdue of the llatley Uill Mine. A section ruuuimr 
 across the ])roperty i'rom west to east shows a high, 
 steep hill in the western part, and a se('(,..d hill (Miually 
 high but less steep, in the eastern part. A small i)ro()k 
 runs in the valley between. These I'eatures are impor- 
 tant, since it will enable you to drift i!ito cither or both 
 hills from the valley ; thus t'ilher se(!urinu' <lraiua"-e 
 easily, or enabling you to work the veins by drilts for 
 the present. 
 
 On the western liill there are two powerful veins, with 
 smnllei" patches of co])per ore in the schists. It is in 
 one of these (No. 1), projected southerly, that the Massa. 
 wippi shaft is being sunk. I ha\e ol)lained specimens of 
 copper ore from this and other veins u[)on your pi'operty

 nviw \'oiii' wesi line is ,1. chloi'itif schist, carrvinfy veins 
 of quart'/ \vi ill veHow copper, mundic, and chlorite, or 
 '*pcnoh." Ill iliis lies No. 1 vein, chiefly composed of 
 paccharoidal ijuartz, carrying copper uniibrmly dissemi- 
 nated throuo;h it. To the east of this, the schists are 
 consider{d)ly dolomites, and then succeeds a hard, choco- 
 late-colored ijuartzite, carrying specks of copper. It 
 slightly resembles el van. Passing by several schistose 
 layers, we come to three distinct bands of rock, closing 
 with the east«'i'u edge of thf Chey are, — 1st. A 
 
 decomposing quin'tzose schist ^, and containing 
 
 much mundi(%\vith a little co^ This is vein No. 
 
 2, and will prove a very Import. for exploration j 
 
 its course is nearly north and south, and is 12 feet wide 
 just over the fence. 2d. A soft, nacreous schist, spotted 
 with crystals of brown spar and mundic; this is not 
 wide. od. A dolomite, quite rusty in its decomposition, 
 and hohling specks of copper. This runs irregularly 
 ul)out N. and S., and even N. 25^ E. Beyond, the hill 
 is very steep, and the next rock is hard chloritic schist. 
 Passing now iij) the eastern hill the ledges are con- 
 cealed by the soil, and near the top is the shaft now 
 being worked by yourself upon vein No. 3 ; it has al- 
 ready been sunk 10 feet. The vein carries copper ore 
 for a width of two feet, with the general course N. E. 
 and S. W.. dipi)'ng from 20^ to 6(^' 8. E. The ore is 
 chieily the yellow sul])huret, with blue and green carbon- 
 ates. The gangue is a mixture of quartz and nacreous 
 shaly matter ; in tlie pure quartz the copper is often 
 condensed into nodular masses. The vein is sometimes 
 parted liy seams of quartz ; and leaders of white quartz, 
 carrying spangles of ore, occasionally drop into the prin- 
 cipal vein. I should estimate the amount of copper

 present to be about 4 por cent, of meuillic coppei Ibi a 
 width of 16 j'nchcfl. Some parts of the vein cany crjrg. 
 tals of dolomite, a matter of coiisidoralde importance. 
 This vein (No. 3) is remarkaldy well defined^ and .t^ives 
 iDromise of yieldin*^ very rich ore in its I'utnre workinj*. 
 There is a fine lot •' specimens taken from it in the tool- 
 house, and fair samples of them have been exhibited in 
 Boston. In the very t-astern portion n\' ilic property 
 the rock is a thick-bedded chlorite schist, carrying veins 
 of white quartz and chlorite. No. 4 vein crosses it, or 
 the one exph)red uj^m the Johnston and William Kmery 
 lots; dolomite is mixed with the copper and mundic in 
 greater amonnt than in vein No. 3. This will make the 
 best smelting ore upon the property. The hill is iiigher 
 here than elsewhere upon th" ])roperty. 
 
 The rock is pretty hard to drill on vein No. 3, and for 
 the depth of eight fathoms will cost $80.(10 per fathom; 
 fitoping will cost $].2r) per s(iuare yard at least. It will 
 be softer at veins 2 and 4. The amount of copper in 
 No. 3 (viz., 16 inches width of 4 per cent, ore) is suf- 
 ficiently great to render the workiii^L,- prohtahle. A well- 
 built dwelling-house and barn is situated upon, and 
 belongs to, the pr )erty. One road from the Massa- 
 wippi outlet to Sherbrook passes through your property. 
 You are 8 miles from Sherbrooke, 7 from the Lennoxville 
 Smelting Works, and 2 miles from the proposed outlet^ 
 station of the Massawippi H. R., which is to connect the 
 Passumpsic RR. at Newport with the Grand Tnuik R.R. 
 at Waterville, C. E. ; you are thus conveniently situated 
 with respect to the transportation of your ores to Boston 
 or the Lennoxville Smelting Works. (See the map ac- 
 companying this Report). Any one of the four veins 
 can be conveniently drained by adits, — Nos. 1 and 2 by 
 the same one. I am inclined to believe that these two

 CONCLUSI(»Ng. 
 
 Ist. There are certainly four veins of copper upon 
 the property, belonging totJ e cupriferous portion of the 
 Quebec Croup of the Lower Silurian Formation. 
 
 2d. Two of these veins contain lime, with mundicj 
 thus foruiing an ore of easily suielting properties, — a 
 fact of the greatest consequence in mining operations. 
 
 Sd. All the veins can be drained by cheaply exca- 
 vated adits; and perhaps in some instances adrift can 
 be run in on the course of the vein. 
 
 4th. The property is advantageously situated, with 
 respect to proximity to a railroad and smelting works. 
 
 5th. Its central location among other mines may af- 
 ford some advantages in the working not enjoyed were 
 it isolated. 
 
 litli. It is in ;i region where labor Is cheap, and the 
 cost of living not expensive.

 The Hatley Hill t]oi)per A'.ine is situated l)etween 
 Little Mao-oo' and Massawippi Lakes, and' is two miles 
 north of 'the latter. It is southwest tVom the copper 
 mines in Ascot, and is seven miles southwest Iroiu Len-

 that it can l)e easily drained 
 
 CHARACTKI! OF THE iJOt'KS \NI» OHES. 
 
 Nacreous argillaceous slati rocks, with numerous 
 veins and beds of white (juartz. is the mining -country" 
 of your copper ore. These rocks bidong to the well- 
 known copper belt of Canada East, which extends from 
 Vermont to Megantic counly. below (ineboc, and shows 
 copper 01 es in may places. Y.-llow c()])])cr pyrites with 
 some purple cop])er ore or erubescite ai'e the working 
 ores qf this mine. Some green carbonate of cop^ar is 
 
9 
 
 seen where the rocks have undergone decomposition by 
 agency of air and water, and this serves to guide the 
 miners in their search for the outcrops of the copper 
 ores. Iron pyrites, as usual, is also contained admixed 
 more or less with the copper pyrites, but is not too 
 abundant at this mine. 
 
 THE MINE AND ORKS RAISED. 
 
 At present only a shallow pit, or incipient shaft, 10 
 feet in diameter and 15 feet deep has been excavated in 
 order to prove the vein. 
 
 A belt of copper-bearing slate, with some thin quartz 
 seams also containing copper pyrites, the whole thick- 
 ness of which is 5 feet 8 inches, has been discovered. 
 Lhis bed dips with the general strata, southeast 40° 
 and It has been traced to soine distance, not less than 
 500 yards in length, on to another mining property to 
 the southwest, where a pit 4 feet deep has been sunk 
 upon the vein, and is now in process of developinir the 
 ore. 
 
 8oon as the snow is off from the ground the outcrop 
 of the ore may be easily traced, only a little soil cover- 
 mg the rocks. 
 
 At present the mining operations are mere explora- 
 tions, and a sloping shaft is to follow the ore as it iroes 
 down with the strata. 
 
 I examined the selected ore stored in the blacksmith's 
 shop on tlie premises, and found the heap to be three 
 feet s(iiiare and high, and to contain about 2 per cent 
 of the metallic copper, as near as 1 could .judge ; pieces 
 cobbed (^lean as they can be for the furnace. 1 brouoht "
