DEVELOPMENT
Prior to 1957. surface drilling revealed over 1/2 million tons of i.98^ copper across enaverage width of D feet. During 1956 i. shaft wes sunk to the ore zone at 1030 feet, the 950 level was developed during tho first six months of 19571 ovtr a 1000 feet, giving 300 tons per vortical foot of 2.03?o copper across an average width 01 ?.7 feet.
Iwenty nine aoles were drilled froiv. the 550 level, 18 of which were horizontal, those increased the tonnage to 1,0^9,000 of 2.07'j copper across an c.verc.{je width of 9.05 feet.
The block covered in 11:, e calculation was600 feet long at surface, 1^-CO feet lon^ at a depth of 1,200 feet, with an average depth of 1300 feet.
The underground development served to investigate the nature or the ore r,nd its extension in depth, there was no attempt* made to increase the oro body laterally.
REGIONAL GECLCGY
The regional geology is covered by Alrahams 1 report pn the "Geology of Pc.rts of Long and Spragge township."
Structurally the area is dominated by the Hurray Fault cone** The fault runs slightly north of east end dips almost vertical. Jt is well developed north of the showing and has proved an ideal course for the highway. .^ ;
To the north of the fault are huronian quartritos and con glomerates, which are uraniferous on the adjoining Pronto property* -x These are intruded by basic dykes and sills ofKeweenawan age,-; South ; of the fault are huronian metamorphics of sedimentary, volcanic"find,-^ igneous origin. It is within these metamorphics that tlae oopp.t^t^S-:*! showing occurs.

The silicified country rock contains bands of the original schist,
the quartz is grey, and sulphides occur along fractures.
The zones rf fractured Tuartz with sulphides are usually surrounded
by breccia ore, which makes a sharp contact with the unfractured quartz, thus
there is a uhfirp fall off of values across the contact,
The silicified zone is mainly confi""^. to the north or footwall *f

STRUCTURE
The country rocks trend east and west and dip south at 80'. The
mineralized zone also trends east and west and dip south, but is flatter and
tends to flatten in depth, from BO 9 to 70".
Thus the vein and the hanging wall rock converge in depth, the

PATER HINE TOUR
Spragge Township, Ontario

W ; ''
PATER MINE TOUR
Spragge Township, Ontario
: ^.v''.•*5r-- rV 1 ."
This tour of the underground workings of the Pater Mine was made on September 6th, 1961, under the guidance of C. Knight, mine geologist. Others in my party included #. Aarden and C. Hod gson. The tour was of added interest in view of the facts that:-
1. the Pater Mine is the only producing copper mine located along the north shore of Lake Huron, although there was a period of sporadic, email scale copper production in the area prior to World War I. The old Bruce Mine, located at Bruce Mines, was the first Canadian copper producer. The north shore is dotted with small copper shovingd, which bear a close geographical relationship to the 'well known 1 Murray Fault.
2. The Pater Mine is located approximately 300 - 400' south of the Murray Fault. Special structural and mineralogical features of the mine may, and probably do, account for the area serving as a locus for the deposition of sulphides.
3. Two unusual factors aided 'Pater', a marginal economic proposition, on it's road from the prospect to the production stage. These were the presence of the Pronto Uranium Mill, which would provide primary concentration facilities, and the fact that Pater Mines had previously sunk a 3 compartment exploration shaft to the 900' (approximately) level.
STRUCTURE
The ore zone is a steeply southward dipping, consistent tabular body, whose length (1200* of mineralization, approximately 900' is economically mineable) and thickness (approximately 8' at the upper levels and widening gradually with depth) are small in relation to the depth, which is an open factor at present. The shaft is presently being extended to the 2100' level.
SSIJ-831
The ore zone occurs within the south limb of a steeply westward plunging dragfold, which parallels the east - west trend ing Murray Fault. The zone widens froai the 8* thickness, at the upper levels, to 23 S in some sections, at a depth of 650 - 800*.
The host rock is a hornblende - chlorite schist, which shows extensive silicification and dragfolding. Minor folds of variable size occur within the main dragfold. Larger fold noses show a tendency toward an increase in mineralization. There is a corresponding thinning along t!.e fold Hanks. This feature is not noticeable on small scale folds.
In zones of intermediate grade ( 2# ) 'copper', where quartz and dark schist bands are approximately equal in quantity, mineral ization is locaiHzed along the contacts or within the schist bands. Massive chalcopyrite - pyrrhotite bands may range in width from a couple of inches to four or five feet. They show only a moderate amount of thinning and thickening alonfc the vein strike direction. Rolled quartz pebbles, ranging from a fraction of an inch to several inches in diameter, are an unusual feature that is found within the massive sulphide sections. It has been suggested that this vac caused by movement which was subsequent to the introduction and consolidation of the quartz. R. Beger ( Michigan Institute of Mining and Technology, M. Se. 1962 ) feels quite certain that the majority, if not all, of the country rocks in the Pater sequence are sedimentary in origin.
ORE GENESIS (per. C. Knight)
Originally the host rocks vere silicified and dragfolded. The main plane of movement was probably along the Murray Fault.
'^•^^^^ ^vRXttl ir^H^- '
- 3 -
As the quartz is interbanded and dragfolded along with the schist,
it appears that at least a portion of the country rock silicification
was prior to the folding. Subsequent movement would fracture the
competent rock and supply the channelvaya for subsequent ore solutions.
The author doesn't recall whether or not there was a thickening on
the nose and a thinning on the flanks of these small folds or not.
C. Knight suggests that there were at least 2 stages in the
mineralization process. It is likely that there was more than one
stage of Hit silicification also. The 1st period of mineralization,
which was pyrrhotite rich and chalcopyrite poor, mineralized the
whole dragfold. A later period of mineralization effected only the
south limb of the fold. Whether the 2nd period of mineralization
bore the same pyrrhotite : chalcopyrite ratio or whether there was
an increase in the chalcopyrite is not known to the author. Either
way, the result was to upgrade the chalcopyrite content of the south
limb. The author is also unaware of the reason for mineralization
only in the south limb, in the 2nd stage of mineralization.
The ore reserves and grade are listed in the Canadian Mines
Handbook - 1961 as 1,032,503 tons and 1.8# Cu, respectively.
ORE MINERALOGY - Hand Specimens
Chalcopyrite represents the Cu ore. Other sulphides include
pyrrhotite and minor pyrite. Assays indicate the presence of
cobalt although the mineral that it occurs in hasn't been identified.
In high grade sections, pyrrhotite : chalcopyrite occurs in a 2 : l
ratio.Hand samples have a matrix consisting primarily of quartz.
It is vitreous to subvitreous in lustre and varies from a milky
white to a smokey grey colour.
if
The rook "breaks with a sharp, jagged fracture edge in a subconchoid-
al to irregular fracture. Occassional chlorite schist planes were
noted also in the siliceous samples.
Generally vithin the hand samples, there will be chalcopyrite
rich sections and elsewhere in the samples, pyrrhotite rich sections.
The mineralization occurs as irregular, branching fracture fillings
in the poor to medium mineralized sections. In the veil mineralized
sections, the gangue minerals have the appearance of being
'inclusions'. The mineralization is homogeneous vithin the various
grade zones ie. veil distributed.
SUMMARY
While this report, which has been based mainly on a brief
underground tour and several conversations with C. Knight, isn't
intended to be an exhaustive compilation by any maans, it does
represent some of the author's personal observations. The majority
of the information consists of the author's recollections of
information imparted by C. Knight during personal communication.

PATER EXPLORATION
•INTRODUCTION
Results of deep drilling in 1962 exceeded expectations; confirming continuity of ore to 3000 ft. below surface. It was considered justified to estimate extension of ore belcw 12th level on the basis of the average tonnage per vertical foot between 12th and 6th level.
Improvements in ore grade and width with deptn and performance, experienced in mining between 6th and 12th levels indicate that the operation will be in the profitable rather than marginal category, to the end of reserves in sight to the 16th level horizon.
Thus the incentive to increase the life -and/or rate of mining by extending these reserves is obvious; b'*t the form future exploration should take is less so.
I believe that this shoalu De a logical continuation rf the exploration programme started in 1962, such as is outlined in Paul Young's memorandum re Pater Exploration, of 23rd Janrary, and I am in complete general agreement with the vi.ews expressed therein.
BRIEF SUMMARY OF GEOLOGY
Observed Facts
A sequence of schists that have been correlated with the McKim of the Sudbury Series dip vertically to 75 0 south, strike N 65 0 to 30 0 R. They are bounded on the north by the Murray Fault, to the south by granite of the Cutler Batholith. The Murray Fault from near surface data, dips vertically to steep south, deep intersections show a marked flattening in depth to the west. The Murray Fault strikes slightly north of east in the mine area, so that schist types are likely to become successively truncated to the east against the fault.
From the Murray Fault, to .some 900 ft. south, rocks are hornblende and chlorite schists, with variable carbonate, biotite and quart?,. South of this point definitely sedimentary schists of arenaceous character aiow contar* metamorphic effects, probably due to the Cutler granite.
A zone of silicification from two or three fe^t to 60 or 70 ft. wide, 3000 ft. long, is indicated by surface exposure and drilling; approximately 400 ft. south of the Murray fault striking due E-W, and is transgressive to strike of enclosing rocks at between 10 to 20 0 .

.',. . '*;:*, v A sulphide zone extends for approximately 2000 ft.along the H.W. of the silicified zone, it is a breccia, the matrix
" 4s almost entirely pyrrhotite, with min. "halcopyrite to giveassays averaging 0.4 to O .&'fc Cu. The ore zone is a part of this
- zone, it is 900 ft. in length, has a proven vertical extent of3000 ft., with a significant increase in grade and width withdepth shown by development to 2100 ft. An intersection at 3000 ft.gave the best grade and width of any hole drilled on the property.
Interpretation
In my opinion the a.mphibole-chlorite schists represent an interbedded volcanic greywacke sequence. A concordant body of amphibolite, which may be intrusive, or maybe the massive lower portion of a thick flow, lies on or close to the H. W. of the ore zone for much of its length.
The Murray Fault and associated structures show evidence of recurreent, south side west movement. The effect of such movement in schists south of the fault, was localised as a fault by the presence of the amphibolite mass; close to the north margin of the amphibolite. This fault was silicified to form the present silicified zone. Further movement caused brecciation along the hanging wall of this zone, the breccia provided an opening for sulphide emplacement, dominantly pyrrhotite. Renewed brecciation and drag folding accompanied by south side west movement on faults parallel to strike of enclosing schists, allowed chalcopyrite mineralisation at the site of maximum re-brecciation or opening developed on faults. Thus the ore zone was formed in a preferred portion of the sulphide zone.
GEOLOGIC FACTORS EFFECTING EXPLORATION
The essential control is the proximity of the amphibolite to the Murray Fault, and the presence of silicified zone was a prerequisite to formation of the sulphide zone, the latter a prerequisite to formation or ore. Thus recent lateral exploration was directed west of the main ore zone, following the sulphide zone; looking for possible ore : hoots where the sulphide zone might have been distruoeci by pre-ore faulting or drag folding. Previous surface cirifling had shown silicified cind sulphide zones to be present to 1000 ft. west of main ore zone, some sub grade intersections had been made, at least one indicated moderate ore grade.
The most outstanding feature of the ore zone has been the amazing vertical continuity of high and low grade zones, and of minor structures -; for example the high grade shoot at the west end of the ore body maintains minor details of its outline
. . 3

*m~. -m-"' -h^r' '-:Sfe'

in plan from the -200 to the -2100 ft. horizon,'although 1 it s length is not more than 135 ft. Other features show a ratio ; r ,. of depth/length of 5/1 to 10/1, and the ore'body as a whole,, might be expected to do the same.
In view of this feature of great vertical continuity, the 500 ft. length of tha sulphide zone exposed in 1201 Drift West on the 12th level can be assumed to be representative of this zone for at least 1000 ft. above 12th level, and possibly below. Two small ore shoots have been located, one of these is approximately 120 ft. long, in the area where the 'F.W. Zone* is overlapped by the main zone, it is indicated to extend from 12th to 7th level {1000 ft.). A short zone from 50 tO 60 ft. long assaying 1.6V5.4 ft. was encountered in 1201 Drift; its vertical extent has not been confirmed, but may be considerable. The rest of 1201 Drift exposed sub-grade pyrrhotite, from 0.5 to 3.5 ft. wide. Both sulphide zone and silicified zone are irregular and ill defined.
In spite of negative results in terms of ore reserves, 1201 drift has provided valuable structural information. It also allows of a realistic evaluation of previous drilling results in this part of the sulphide zone between 9th level horizon and surface. Such an evaluation shows that between the west end of the main ore zone and a point 500 ft. west of it, nothing resembling a repetition of the main zone exists. Small shoots of marginal ore exist, very few in number and limited in length.
Drilling from 12th 3evel shows the Murray Fault to flatten in dip to the west; drilling through the fault shows probable sheared Gowganda quartizite; to be expected north of the fault. The projected point of intersection of the silicified zone and the Murray Fault lies two to three hundred feet west of the present face of 1201 Drift. I believe the drift should be extended for two reasons:-
{a) Possibility of finding another small ore shoot
(b) The area of intersection of fault and sulphidezone is of interest, as to whether the fault hasa favourable or unfavourable effect on ore occurrence.
The silicified zone extends 1000 ft. east of the east end of the ore zone; shown by surface drilling. Such drilling encountered low grade sulphides or minor sulphides. With one exception, such drilling was not deeper than 500 ft. below surface. A marked grade cut-off was encountered at about the -500 ft. horizon, for the greater part of the ore zone; this is possibly associated with a reversal in dip of the ore zone at this horizon.
SSM-531
- Page Four -
Thus it is possible that additional ore zones exist along the silicified zone, east of the known ore zone, and below the easterly projection of the -500 ft. grade cut-off. It is proposed to test this possibility by surface drilling to the -1000 ft. horizon. The presence of a strong, well defined silicified zone, with appreciable pyrrhotite would justify further drilling, even if ore grade is not encountered in the first hole.
Surface mapping east of the ore zone, and drifting short distances east of the ore zone on several levels, indicates that the amphibolite, which is here north of the silicified zone, is narrow and ill defined in this area. Thus if the assumed importance as a controlling structure of the amphibolite is real, ore shoots found east of the main zone are likely to be limited in extent.
A surface drill hole, M-46, encountered a strong sulphide zone which gave a marginal copper assay 100 ft. below surface, 400 ft. north of the eastern part of the main zone. M-50 passed 400 ft. vertically below this, and found nothing.
Outcrop a short distance east of M-46 shows no indication of sulphides. This may have been a small lens of sulphide breccia isolated on a drag-fold; but it should be investigated by drilling short surface holes on strike; and possibly by drilling north from 6th and 12th level (East end) to the Murray Fault.
Approximately 1/2 mile east of the mine, two small pits just south of Hwy l? show narrow and irregular pyrite lenses in Gowgaiida quartzites; with marked associated gossan. This also should be investigated by surface drilling at a depth of 150 to 200 ft.
Numerous gossan zones have been mapped west of the mine, on outcrop close to the shore of Lake Huron. They are of limited extent, md although they appear quite strong, it is extremely difficult to find any sulphides. It has been noteu that they occur along a particular tr;jnd, in a schist horizon which has been found to consist in places of a metamorphosed conglomerate. Thur they may represent minor pyrrhotite mineralisation contemporan eous with that of the ore zone; or quite possibly represent slight accummulation if iron minerals in an original conglomerate. E.M. surveys over such gossans in the vicinity of Spragge village show virtually no response. It should be noted that E.M. over the mine area showd extremely high response, even over sub-grade sulphides.

Surface mapping on a scale of l" to 100 ft. indicates the possibility of folding or drag folding in the north contact of the (Spragge church area) amphibolite. The area of grefcest interest is not exposed.
If such a structure exists, .6 should be drilled at a depth of about 1000 ft. Before drilling is poposed, the area should be mapped in close detail, on a scale of l" s 20, this will help to establish the reality or otherwise of the assumed structure.
Old prospect pits, are reported in Long Township, between three and four miles west of the mine. These must be located q td examined; and the remaining unmapped exposure of Sudubry series rocks in Long Township mapped on a scale of l" ^00*
POSSIBLITIES IN DEPTH
Development above 12th level (2100 ft.) indicates that the centre of gravity of the ore body has not been reached. Improvements of grade and width have been noted.
The deep intersection of U12-20, 2 .82*70 over 33.5 ft. is*the best obtained on the ore zone; at -3000 ft., and may show a grater width than at 12th level or at any point on strike. Obviously, no statistical significance can be attached to this for the purpose of projecting ore reserves; the average grade and tons per vertical foot from IPth to 6th level were used for this purpose. Nevertheless, such an intersection 900 ft. below the lowest developed Ifvel, with great vertical persistence and improvement with depth, is highly encouraging and was obviously among considerations deciding shaft deepening.
Th^ indication of change with depth is significant in regard to exploration. Average grade of 2.82^ Cu. is higher than other intersection of widths in excess of 10ft.; but gold and silver values were also notably higher, up to 0.03 oz. gold and 0.55 oz. silver were obtained from some section, as well as a very low Ni. assay (all previous Ni. assays reported Trace). Milling results to date shows that gold in the ore, although extremely low (0.008 oz/ton 1961 mill head) responds to concen tration with chalcopyrite to about 0.06 oz/ton, together with part of silver, and makes a modest contribution to revenue.
Thus deep drilling from 15th level or 16th level horizon at as early a date as practical, is essential to test the continuity of ore to the 4000 elevation and possibly deeper; also to check the possiblity of further favourable change in metal content. It is of interest that an increase in gold content to an average of 0.01 oz/ton recoverable would write off the cost of shaft sinking, if tons per vertical foot renan constant.
SUMMARY AND CONCLUSIONS
(1) The presence of a silicified zone and sulphide(pyrrhotite) zone are necessary prerequisites to ore formation. There is a strong structural association of the ore zone with an amphibolite mass of contrasting competence with other rocks.
(2) The silicified zone extends approximately 1000 ft.east and west of the ore zone; the sulphide zone possibly 1000 ft. west.
(3) A few minor ore shoots have been found to the west, the east is an unknown quantity, but ore shoots found are likely to have limited lateral extent.
The likely contribution of either to ore reserves may be two small stopes per level, which although of obvious value, are unlikely to justify extensive exploratory development in their discovery.
(4) Other and completely distinct ore zones may exist on strike, but if they show the same tremendous vertical continuity of structure, they would be indicated on surface at least by a zone of silicification, probably by sulphides, although these might be sub-grade.
(5) Except where positive indications of sulphides are known, or a definitely favourable structure has been outlined, thire is no justification for exploration beyond limits of the silicified zone. Exploration east of the ore zone should take the form initially of surface drilling.
(6) Should drilling results justify drifting, 1300 ft.of drift would explore the silicified zone to its probable limits, both east and west, at 12th level.
(7) Drilling in depth from 16th level has the bestchance of substantially increasing ore reserves, in an area where there are indications that increased metal content may offset the cost of sinking.

ABSTRACT t uasNEssos SPRAGGE I?AI SPRAGGE 040
The regional geology of the Blind River area, and the
geology of the Pater mine are described. In particular the problem
of the origin of the amphibolite rocks which enclose the Pater copper
deposit was investigated. Compositions of the minerals of these
amphibolites were determined. Model analyses of 16 samples of
amphibolite were made, and chemical composition for these samples
were composed and plotted on various diagrams. Examination of these
diagrams showed that the amphibolite rocks are chemically and
genetically related igneous rocks of basalitic affinity, and
thus represent.la series of lava flows or less likely a
differentiated sill.
It was noted that the linear trend of Na2o in the
amphibolite analyses does not agree with the postulate that the
amphibolite were formed by differentiation of a basalitic magna.
This anomalous trend of N?2o is readily explained by late
metamorphic replacement of hornblende and pagioclase by
chlorite and epidote.
Textures and structures of the amphibolite rocks
are described and interpreted.
Field observations showed that the Pater copper
deposit was ( ) by a narrow steeply-dipping fault zone which
cuts the amphibolite at a small angle. Mineralization occured by
hydrothermal replacement of the amphibolite rocks along this zone,
and this replacement was indeed by rather continuous deformation
in this zone, with contempraneous activity of H 2 O, H2 S and CO 2 which
were present and/or introduced in this zone. The ( ) of
replacement was found to be chlorite, quartz, ( ) and minor

pyrrhotite (first); pyrrhotite and minor chalcopyrite;

mineralization took place at temperatures less than 600 0 C
Secondary controls which favoured sulphide
mineralization were ( ) on crests of drag felds
and brecciation of massive amphibolite, particularly at
the contact between massive and schistese amphibolite.

The amphibolite rocks are chonlcally *rd gwietically related igneou*
rocks of basaltic affinity. They represent either a ceritts of lava flou*
or a large differentiated sill.
The biotite-rich amphibolite rocks, which are highest in SiC^, but
low in Na?0, were originally rirfi in ooth SiOg and Ka^O as a reault of
••^.matic differentiation, but at a later time they suffered depletion in
Ka^O and

In the amphibolite rocics deformation took place *ainly in the font of
shearing along nearly vertical planoo, and parallel to thesa planes a well
developed schistosity was produced. As defornation progrease* soae small

Intense metamorphic aogregstiot: of material rich in quartz and plagio

Iron was present in the wall rocks in amounts in excess of that
-f*r*-chlorite. wTiile chlorite wan forming in the ore zone, exceae
iron oxides probably reacted with H? S preseiit in hydrothermal solutions to
produce pyrrhotite. In the final ccAf etition betsevn chlorite and pyr
rhotite for iron, pyrrhotite Martially replaced crifcirul chlorite, and
in so doing produced new chlorite of scnswhat lower iron content.
Chalcopyrite niaeralitation reached its peak in late stages of de
formation along the ore break, and during these stages it replaced pyrr
hotite preferentially along pyrrhotite-quartt and pyrrhotite-chlorite
bouadarift* And filled late fractures in quart*.
In the final stagts of mineral i sat ion pyrite replaced pyrrhotite in
small mounts.

When Pater Uranium Minee ceased operations, the shaft was 1023 ft. deep, 950 ft. level had exposed ore over strike length of 800 ft.
During 1959 the possibility of mining the Pater deposit after such time as the Pronto Uranium operations ended was considered by Pronto. It was recommended that the shaft be dewatered and future drilling done from 950* level.Worked commenced in January, 1960,indicated ore to a depth of 2250 ft, from surface, and development was completed during 1960 preparatory to mining ore above 950' level. At the same time the Pronto plant was modified to produce copper concentrates, and milling started in January, 1961.By January, 1962, it is planned to have shaft deepenedto 2300 ft. and development under way for mining between2100 and 950' levels. Drilling in 1961 indicates than anapproximate reserve of 1,000,000 tons e about 2.00ft willremain after one year's production and suggests thatstrike length is maintainted to 2150 elevation withconsequent favaourable prospects of continued downward extension,
GENERAL GEOLOGY
The dominant feature is the regional Murray Fault. This is approximately followed by the C.P.R right of way north of Pater shaft, it strikes approximately E.W. and os indicated by one or two drill holes, dips vertically. North of the Murray Fault are Huronian settlements, including the basal Missassagi, which was the initial cause of interest. South of the Murray Fault is a narrow belt of metamorphic rocks, mainly striking between N to E and N80E, dip ranging from 75 0 south to 80 0 north, south dominant. These rocks have been tentatively assigned to the Sudbury series. (J.A.Robertson, Regional Commissioner). A cross section through the mine area shows the following :1. 1000 ft. south of the Murray Fault buff-brown qtzite.2. 1000 ft. to 900 ft. south ( )qtzite to qtz (
schist, variable ( ).3. 700 ft. to 600 ft. south fine grained dark green schist,
broadly described as honoblende schist, but showing several ( ) horizons, ore section is almost certainly a stretched conglomerate, and the whole is considered to be ( ).
4. 600 ft. south to 800 ft. south, variable in width, massive medium to coarse grained rock, approximately a meta-gabbro. Reference to as 'Epidiorite' in descriptions of Pater geology upto present time. Amphibolite is a more correct nawe (R. Berger) In { ) the south

margin is ill-defined(gradational, the rock fine grainedand schistose) Towards north margin, grained size increases.At north margin, there is a well defined contact with next rocktype described. This contact is a valuable marker horizon.In my opinion, this is a conformable intrusive (or extrusive ?)5. 500 ft. south to 400 ft. south variable width. Hornblende
schist averaging one or more clear band, of quartz eyes, generally flattened ovoids appear {J"x 1/1 x 1/16 ?) Quartz is discontinuous, matrix contains ( ) chlorite and biolite. This rocks has been variously described as ( )schist or quartz peeble conglomerate. In several weathered specimens seen, the qtz. eyes very much resemble flatter pebbles of recent gravels. I tend to accept sedimentary origin.The best defined pebble bands, occur at or close to the amphibolite contact. Three to ten feet of this rock are chloritized and ( ) against the N.W. contact of the ore.
6. Ore - 400 ft. southA breccia the fragments of which range from white qtz. to silicified schist to chlorite chists. varying in size from a few mm. to several inches. Matrix consists of pyrrhotite and chalcopyrite, in variable propportions, probably pyrrhotite predominates. Occasional pyrite is present, appears later than other sulphides.
7. Silicified ore - variable to 400 ft. southThe ore may be said to lie on the N.W of this zone, which varies from 15 to 40 ft. in width, grading from grey-white qtz. at the ore F.W. contact to slightly silicified hornblende schist away from the ore. Averaging qtz. content may be 70 to 80%. Scattered sulphide breccia bands, usually high pyr. low up.
8. ( ?) Honbblende Shcist : undifferentaited. up to Myrray Fault. Little surface exposure in mine area. Drill cores show a ( ) consistent fine grained grained rock.
Structural Geology : The major dimensions of the ore body one thought to have been controlled by Jrag fielding and brecciation at the silicified zone. The disposition of rich ore shots within the limits of the ore body is believed to be controlled by a) Soci (?) of brecciation due to effect of initial drag folding or to competency of wall rock, b) Attitude of the ore structure - pinch and smell due to relative H.W- F.W. movement.
There is some indications that mineralization may have occurence in two (or more)stages, separated by a time interval. This remains to be investigated by microscope work.

Dear Mr* Buckles:
rei Pater Uraniun Minos
I have rocoived the plane, sections and geological report covering the results of underground development at tho aino. I want to thank you and the coapany for providing our Department with this information.
l' have sent a memoranda* to Mr. R*V, Scott, Chief. Mining Lands Branch, stating th.it, in, my opinion, the coapany ha o found a mineral deposit of economic importance, dipping southward so that it probably underlies tbo lake at depth* This should help in your application for a licence of occupation*
With best regards,
Sincerely yours.
