-S! ' This property lies Immediately north of the Aquarius property x6f Pardee Amalgamated Mines'Limited, immediately south of the May lake property of P'.um Uranium Mines Limited, immediately west of .Magoma Mines Limited, and immediately east of the Mccabe lake-property of Stancan Uranium Corporation. This is in the centre of Township 143, Blind River uranium area, Sudbury Mining Division, Ontario.

Accessibility

Tnis property is best reached by driving north up the Quirke lake motor road from the Spragge turnoff a distance of about 12 miles, thence up the branch road to the Algom-Nordic lake shaft, .and thence by tractor road to Pardee's Aquarius property. This is immediately south of your property. The alternative method of 'reaching this property is to fly from the Laugoma Airbase at Algoma Mills on Lake Lauzon, a flight of 22 miles, to Hou&h lake at your property. Algoma Mills and Spragge are on the Sudbury-Soo lino of the C.P.R. and on Trans-Canada highway No. 17.

Topography, etc.

* The north and south shores of Hough lake are formed by cliff-faces of Mississagi quartzite rising 10C and 150 feet respectively above the lake. Much of the surface is strewn with angular quartzite boulders or erratics, including the above-mentioned cliffs, ' 'ive Streams incise the locally sharply marked valleys which traverse your western clalmo, which are devoid of bedrock outcrops.

Hydro-electric power would be available from the new feeder powerline from Spragge to Quirke lake, about four miles southwest of your property, if required for mining. An ample Industrial water- supply would be available from Hough lake.

GENERAL GEOLOGY

f.; O.;tcrops of Mississagi quartzite occur predominantly in an east- west direction at the higher elevations of fifty to 150 feet above Hough lako, as shown on the accompanying geological map. They comprise two main ridges, one north of, and the other south of Hough lake .

"Recent" glacially derived and redistributed angular boulders doubtlessly constitute "raised" beaches in certain aggregates. These .date from the epoch o? "Greater Lake Huron" flooding the north shore .area to great depth, and measure two to three feet in diameter, or length. They even occasionally reach a length of ten feet. Sandy

' - ,

The Huronian'strata mapped by the writer on the Hough lake , group appear to comprise the upper horizons of the Mississagi V-Quartzite formation. This was found to be at least 2800 feet in .;f thickness by Magoma's drill hole at Pecors lake Just east of your ^'property. This vertical hole intersected sediments down to 2800 -feet where it entered a diabase sill and was discontinued. ';; - Keweenawan diabase dykes traverse large areas of the Blind t. River rocks in certain sections, but the Hough lake property is traversed only by comparatively narrow satellitic diabase 1ykes.

LITHOLOGY

The most common rocks outcropping on your Hough lake property are white to brown-weathering quartzite, the latter phases being cut by feacture fissures. On detailed observations, this formation is no*-ed to comprise the following superimposed recurrent types:-QuartzItes

The quartzite member of the formation varies from a fine-grained, white, homogeneous, compact type up to ten feet thick, to a variengated cross-bedded phase of quartzite exhibiting a more or less well-defined stratified condition.

Beige i;o pink quartzites Indicate the felspathic and arkosic varieties. An example of a red "arkose" underlying thick pebble conglomerate cliffs occurs close to the south boundary at line 4 east. This horizon of "arkose" appears to correlate with a pink quartzite observed at the base of a cliff topped by pebble conglomerate. It occurs at the Base line and line 4 west, and indicates a southeast strike locally.

The arkosic quartzite, where it consists of as little as ten percent of felspathic grains, can be seen in the south shore area. Elsewhere, the arkosic quartzite may appear a salmon-red colour, owing to the high felspar content.Thin Shaly S ridstone

A pea-^reen shaly sandstone; is seen at intervals intercalated within quartzites and pebble conglomerates. The sandstones attain thicknesses as great as fifteen inches, and are most noticeable on .the north shore section of the property. Thes? strata occur sharply .or, abruptly intercalated as separate strata, ^.ui may indicate the

Keweenawan .

A diabase dyke outcrops at intervals across the full width of "r;the property, attaining widths up to forty feet. The rock is ^typically massive, deep green in colour, and possesses a porphyritic ^appearance . Trtis is due to an abudance of euhedral felspar laths, the balance consisting largely of pyroxene and mafic minerals in the form of medium-grained crystals. Rusty seams were noted in one sample, but no pyrite or magnetite. Chilled crystallization is typical of the dykes in contact with the Huronian strata.TECTONICS

" Your Hough lake property is located on the south limb of a well- defined synclinal structure. This 13 eompo-jed of Huronian strata superimposed Gtratigraphically on early pre-Huronian r ^ocanbrian granites, gneisses, plutonic Intruslves, and volcanic rocks. The synclin follows an east-west axial trend, and has a width of seven or eight miles. .Its base shelves to the surface at Whiskey lake some six miles to the east. The syncline extends west for 25 miles, where it widens to a great width.

This middle "basin" is the central of three major east-west synclines in the Algoma uranium district. Locally on the Hough lake property, structural stresses appear to have swerved the strike to a northerly direction, while the Mississagi sediments generally dip as much as 35 degrees westerly.

Tne norti ly strikes observed on the south half of the property may be taken as reflecting the marinal east; end shelving of the nose of the syncline against the Whiskey lake pre-Huronian granite gneiss and volcanic precambrian complex. Convergence of strike and transverse faulting was observed at the lake shore on quartzite outcrops four hundred feet east of the 5^ foot waterfall at the foot of Hough lake.Strike -shear ing was observed across widths up to ten feet. It is related to a quartz vein stockwork over 400 feet long, traversing .ojuartzites at lines 8W and 12W, within 120 feet of the south boundary

conditions/ -.

l'^' . The variable observations of the strikes and of the Huronian ostrata indicate that profound variability characterises the local ^.structural attitudes within the structure underlying your property. Hence a forecast made on the average dip ae observed here might lead to an inaccurate estimate as to the depth of the basal quartz pebble conglomerate strata.

Thick strata of argillites characterize the horizon overlying the uraniferoua ba^al quartz pebble conglomerate in the Quirke lake area. As noted above, a drill hole on your east boundary, had still not reached the argillites at 2800 feet vertical.

MINERALIZED OCCURRENCES

A system of quartz fissure veins, breccia, and quartz vein stockwork was observed over a length of 400 feet close to the south boundary in the vicinity of lines 400* west and 300' west. Here a'a shear zone up to ten feet wide strikes southeast, with quartzite outcrops occurring on a hill summit. A second stockwork of quartz veins ninety feet south of the first was noted to have a width of twelve feet. A thirty-inch quartz vein, possibly related, strikes southeast in this vicinity also, as shown on the attached geological map. Thinly disseminated pyrite was sampled as coe wall rock of a quartz vein breccia one foot v/ide. T r. i s quartzite zone strikes 98 degrees within forty feet south of the main shear zone. On testing for uranium by scintillator, negative results were obtained.

Numerous quartz veins ranging up to three inches in width were encountered traverslng pebble conglomerate at a point some 1600 feet north on line 4 east. These are doubtlessly related structurally to the aforementioned quartz vein stockwork.

Fracture seams containing pyrite vere noted at Ir-solated points on the north and south shore outcrops of quartzite and pebble conglomerates, e.g. in the vicinity of 28 north baseline and line 8 west, south base line vicinity. When tested for uranium content, results were considered negative.

GEIGER SURVET REPORT SUPPLEfflSTARY TO GEOLOGICAL REPORT

ON THE HOUGH LAKE PRCPERTT. ? CALLIRAN PLIN FLON MINES LIMITED : i|

GENERAL ; "The property consists of twenty claims located north of the middle

IjHh of the "S" shaped fold of the Blind River uranium belt, and is adjacent

to the Pardee Amalgamated Uranium Mines Limited "Aquarius'1 property. The

south boundary of the claims is approximately three quarters of a mile to

the north of the contact between the basal beds of the Huronian and the

older Algoman and Keewatin rocks.

The basal section of the Huronian contains the favorable uranium

bearing pebble-conglomerate beds and these dip to the north at approximately

250. It is likely that they will enter the Callinan claims at an approximate

depth of 3,000 feet.

Drilling on the Pardee group has proven the existence of these beds

to within approximately 2,000 feet of the Callinan boundary, and consequently

deep drilling is recommended for the Callinan claims.

In addition to the geological survey a geiger counter survey was

carried out on the group. This survey did not disclose significant radio

activity to be present in surface exposures on the claims.

The details of location, accessibility, topography, etc. have been

fully covered in the geological report.

GEIGER SURTEi

Two east west base lines were cut across the property for a total

distance of 11,000 feet, one on the north side of Hough Lake and the other on

the south side. North-south picket lines were then turned off from the base

lines every 400 feet, and pickets were placed on the picket lines at 130*

intervals.

The geiger survey was carried out by three men using a Precision

Radiation Instrument Inc. Model 107-B geiger counter and two Electronic

-"'-' :-. --S-33P3BSB-: , -.-^ x ^. ^*RBg!

Associates EA 100 geiger counters. The 107B instrument is metered and-.j '':.i',t , V. - , -. -' - . , .-. . -.. ~

measures radioactive in milliroentgens per hour (mr/hr). The. instrument

was calibrated against a standard radioactive sample.

The survey was carried out by the party chief following the

picket lines with the 10?B counter and the two helpers geigering the out

crops on either side of the picket lines. The property was thus covered

at approximately 100' intervals.

Radioactive readings on overburdened and outcrop areas were

found to vary between .005 mr and .01 mr per hour, which is no more than

the normal background count of the instrument.

COMCLUSIOH3

Since no significant radioactivity was found to exist on

the surface of the claims no further surface exploration is recommended,

and future work on the property should consist of the drilling of deep

holes to encounter the favorable uranium quart -pebble conglomerate

horizon at depth.
