REPORT 
 
 OP 
 
 J. F. BOYNTON, GEOLOGIST, 
 
 North Siioue of Lake Soterior, 
 August 11, 1846. 
 Jams Bell Forsyth, 
 Sir, 
 I was emplnvofl in .Time Inst, to accompany 
 ail Kxpl<)rin,!v Kxpedilion on tho, Novth Sliore 
 of Lake SniH;rior, inuler tlie direetioii of Col. 
 C. IL Gratiot, to select Mineral Lands for the 
 location of a Permit belongin,^ to you. 
 
 Accordingly, on the Gth of -Tidy, in company 
 with W. K. "Logan, I'^sil. I'rovineial Geolo- 
 gist, we left Copper Harbor on the Schooner 
 Occ'a?}, bound for the Canada shore, and we 
 proceeded up the Lake to examine the Islands 
 and Coast, being between Spar Island and 
 Pigeon Iviver. 
 
 Our attention was particularly called by 
 Mr. E. 11. Thomson, to some large \ ems about 
 sixmiles west of Spar Island, where, after a 
 careful examination, we decided on locatnig 
 your Periuit. 
 
 The Location is situated about seven miles 
 east of the Boundary Line betwe .i the Uni- 
 ted States and Canada, on the mam Sliorc, 
 including a large peninsula of higli lulls ex- 
 tending into the Lake about two uules, belund 
 which w a most excellent Harbor, where ves- 
 sels may lie safely secured from storms commg 
 from any direction. 
 
 rJVEBS. 
 
 There are two Rivers emptying into the 
 Lake from this Location. One of ihem is four 
 rods wide with six feet of wuter over the bar 
 at its mouth. 
 
 We passed up this Piiver one mile and a half, 
 and found the water irom three to six feet 
 
1 
 
 3 
 
 deep. At this distance tip the River, there is 
 a Full that Avould afford an excellent water 
 lower I'or propelling any Machinery that might 
 required for Mining operations. 
 
 SOIL. 
 
 At the mouths of these Rivers, there is a 
 large delta of fine rich l;ind tliat woul(l \e 
 easily cultivated, and affoid an abundant crop 
 of all the products of any country of its lati- 
 tude. 
 
 WOOD AND TIMBER. 
 
 The high land on the Location is covered 
 with a small growth of Sin'uce, Pine, Poplar, 
 and Birch — but on the low lands, and on the 
 sides of <he Rivers, there is a large quantity 
 of fine Timber that will be found highly valua- 
 ble for building, curbing, and other Mining 
 purposes. 
 
 ROCKS. 
 
 The prevailing Rocks on the Location" arc 
 the Syenetic and Greenstone Trap, thrown up 
 in immense dykes, running nearly in a north- 
 cast and southwest direction. These Rocks 
 are traversed by numerous Veins of (Juartz, 
 Calcareous Spur and Sulphate of Barytes. 
 
 VEINS. 
 
 The Veins on your Location, as is usual on 
 the North Shore of the Lake, arc much larger 
 than those found on the South. 
 
 Vein No. 1 is on the western point of the 
 Location. 
 
 Its course bears N. 34°. W. and S. 34°. E. 
 dipping 72°. E. It is four feet wide ; the 
 wall rock is Greenstone Trap. The greater 
 jiort of tills Vein is Calcareous Spar, but on 
 the east side of the Vein, being against the 
 wall rock, there is a portion of Sulphate of 
 Barytes about one inch thick. 
 
 On the west side of that, is Calcareous Spar, 
 four inches thick, separated from the larger 
 portion of the Vein, by Veinstone from four 
 to six inches thick. 
 
On the inside of this, there is a thin portion 
 of highly crystiillized (Juiirtz, half an inch thick ; 
 on the west of tliis, is Calcareous Spar, eigh- 
 teen inches thick ; on tlu; other side of this is 
 Crystallized Quartz again as on the east side. 
 This (Quartz has a portion of Veinstone on its 
 west side from four to six inches tliick, fol- 
 lowed by Calcareous Spar, five inches thick, 
 being in contact witli the western wall-rock 
 of the Vein, a form of which will be given on 
 the plat of Vein. 
 
 In this Vein, I found Iron Pyrites,^ Spathic 
 Iron, with indications of Lead and Copper. 
 
 CROSS VEINS. 
 
 There are cross Veins intersecting this Vein. 
 The course of the first is N. 3G° E. four feet 
 wide; the second, one foot wide — course bears 
 N. 47°E. The third bears N. 31° E.; and 
 the fourth N. 51° I'L At the point, where 
 No. 1 and 2 Cross Veins unite with the miiii 
 North and South Vein, they form one large 
 Vein, eight feet wide. 
 
 VEIN No. 2. 
 
 Its course is N. 45° W. and S. 45° E. It 
 dips 80° to the east. This Vein is made up 
 of several small ones, that unite and form one 
 of ten feet wide between wall-rocks. This 
 Vein is mostly Sulphate of Barytes with some 
 Calcareous Spar, with indications of Copper. 
 Profet. or Mather reports to liave found Copper 
 in this Vein, while on an Exploring lixpedition 
 last Fall, for Mr. Prince. This Vein can be 
 traced to the opposite side of the hill. 
 
 VEIN No. .3. 
 
 This Vein is eight feet wide. Its course 
 bears N. 30° W. and S. 39° E. In this, we 
 found Spathic Iron with traces of Copper and 
 Lead. This Vein passes out of tlie Lake into 
 a cliff of rooks about 30 feet high, and run- 
 ning in this Rock about 20 rods, cuts directly 
 through an immense hill of Trap Rock, about 
 four hundred feet high above the level of the 
 Lake, and is found on the other side of the 
 hiU. If a shaft should be sunk on this Veim 
 at the side of the hill, and then drift into it, 
 there is every reason to believe that it would 
 prove rich in Minerals.

 VEIN No. 4 
 
 l8 a few rods East of No. 3, nnd is three feet 
 wide ; its course boinp; N. 30" W. and S. 30° E. 
 dip 7f>" E., and is coiii])i)Sfd of Calcareous 
 Spar, interspersed witii Quartz. 
 
 VEIN No. 5 
 
 Is found on the iiortli side of tlio peninsula. 
 Its course boars S. 3«° W. Tills Vein is com- 
 posed of about equal i)arts of Calcareous Spar 
 and .Sulpliate of Jiaryk's. It is eight feet 
 wide at the top of the hi'!, about two hundred 
 feet back from the watui-, and three hundred 
 feet above the level of the Eal<e. It being 
 covered villi loose rocks on the shore, pre- 
 vented usfrom asccrtuiciin;^ its exact width at 
 the water, without besiowinir nio.'c labor than 
 we were prepared to do at the time; but judg- 
 ing from (he parts of tlie \'ciii exposed on the 
 top of tiic hill, we tiiduixiit it must be (en to 
 twelve feet wide at tlic Lake Sliore, as we gen- 
 erally find them to grow wider as they de- 
 scend. 
 
 This is a noble Vein and I woidd recom- 
 mend (liat an adit be opened into it nearly on 
 a level with the Luke, early in tlie spring or us 
 soon as (he Company may make arrangements 
 for practical Mining operations. 
 
 On the surface of this Vein I found a large 
 quantity of Spathic Iron. 
 
 This Mineral I hove found on the surface 
 of all the Veins that have been opened on the 
 North Shore of the Lake which contain the 
 Sulphurets of Copper. 
 
 VEIN No. e 
 
 Is 1^ inches ■wide. Its course bears S. 31° E. 
 composed of Sulphate of Barytes. Its wall- 
 rock is S) enetic Trap. 
 
 These Veins are all found on the peninsula 
 and form the greatest concentration of Veins 
 I have seen on the North Shore of the Lake. 
 
 There are many other small Veins or 
 "feeders " to the larger ones, which I do not 
 describe, as I report none that are less than a 
 foot -wide.

 VEINS No9. 7 AND 8 
 
 Arc situated on the iiiiiin land about one 
 mile up the lliver, and Soutli of it ii mile and 
 a half. Thiy are in a ran-,'u of Greenstone 
 Trap Hocks cxtciidin-,' in a Southwestern 
 direction IVoui tlic mouth of tlie lliver as iar 
 as the eye can reach. 
 
 These Veins are coinposf^d of Calcareous 
 Spar, each one foot wide, with perpendicular . 
 wall-rock, and present a very good appear- 
 ance. 
 
 Mr. Gratiot forwarded to you .about four 
 weeks a"o, ii box of Specimens taken from the 
 diflereiir ^'eills. They are surface indications. 
 
 There are probably other vabuiMc Veliison 
 the Location whichhave not yet been disco- 
 vered, as the woods are tull of underbnisli, 
 and the rocks covered with soil and moss, so 
 that it is very hard to find thein only where 
 the rocks outcrop in the sides of the lull and 
 expose them to view. 
 
 In order to test these Veins I think'it will 
 be necessary to sink shafts on them, as they 
 arc jreolonicallv situated from forty to si.Kty 
 feet above the "rocks on the Locations where 
 Ores arc now found. 
 
 Should I find any new indications on ana- 
 IvsinK the Siwcimcns from this Location alter 
 my return east, you may hear i'rom ine again. 
 
 Respectfully your obedient servant, 
 
 J. F. BOYNTON, 
 
 Practical Geologist.
