The cluinia ore ovmcd by Tlie Algoraa Steel Corp., Ltd. tind were staked in June, 1966.
Reason for Survey
To outline a magnetic anomaly previously outlined by an airborne magnetic survey.
Results of Survey
Two anomalous areas of approximately 6,000 feet and 150 feet average width were outlined.
Type of Instrument
The instrument used was a MePhur M-500 Fluxgate Magnetometer. The sensitivity of the instrument is 20 gammas per aenle division on the l L range.
Instrument operators (a) J. E. Gray39 Pageant Drive Sault Ste. 1-brie, Ont.
Ills qualifications are:(i) Technician with Mclhar Geophysics Ltd. for 3 years, (li) Ten year Field Technician with Algocn Ore Division.

Method of Survey
A line grid was laid out aa shown on the accompanying pTin. Tills grid totalled 9.5 miles. Cross sectional lines were cut nt 1*00 i'eet ^Intervals except where intermediate lines were cut nnd these were at 200' Qpacings.
previous mentioned cross oectionnl lines were turned off at 90* angles off of a picketed base line.
Chainage pickets were eo k.abliohed nt 100' intervals ulung cross sectional lines.
Magnetometer rendiugs were taken o t 25' intervals. A tot--:l of 1,799 readings were recorded.

RJRTOSE OF REPORT
Submitted for assessinent work credits.
PROPERTY LOCATION AJTO ACCESS
Claims are located approximately one mile west of Javant Lake and 18 miles north of Savant Lake Station. Access "by aircraft or portr.^c from Savant Lake. A tourist camp road is presently being built from Highway 599 to The Narrows; progress thus far to Snowbird Lake vicinity.
PREVIOUS WORK*
A magnetometer survey over a baseline length of 9,600 ; has been completed; crossline intervals at 200 - 'tOO feet. No other work has l-een done.
CLAIM STATUS
Claims are held by The Algoma Steel Corporation, Limited, Miner's Licence A20^38. Stakinc was done in June, 1966. A total of 27.9 credit days per claim had been applied upon completion of geophysical surveying, dated !-hy, 1967.
Tlie Standing Bear claims come open on August 7, 19&8. Present assessment applies for a total of 2^5 credit days on 6 claims.
CLAIMS MAPPED
PA38173 to PA38177 inclusive; PA3680!. A total of 6 claims.
COVERING DATES
June l, 1968 to June 17, 1968.
GEOLOGY
General geology of the Savant Lake area is described by E. S. Moore iu his report entitled "Lake Savant Iron R-nge Area" O.D.M, 1910.

GEOLOGY COM?'D.
Present mapping at a scale of I " * 200' lias been completed overthe magnetometer survey grid. Cror.slinc interval varies between TOO to J*00 feet. All outcrops visible from the baseline and crosslines have been noted.
Examination of outcropping indicates that altered greywacke and banded iron formation comprise the two main rock types in the grid area. Minor convoluted quarts veins also occur.
The greywacke is the country rock for the iron formation; with few exceptions iron formation bands make up no more than 1^ - 20/5 of any particular outcrop. The greatest width of iron formation observed was about 20 feet at CL51+OOE. Great widths of altered greywacke with minor iron formation bands and small quartz stringers were the most common outcroppings observed.
Tlie greywacke is mainly of a m? s, s i ve appearance but occasionallyexhibits a slaty cleavage which runs in a vein-type structure extending for several feet in a linear fashion.
The banded iron formation is composed of alternating layers cf magnetite and quartz, usually fine-grained. Individual iron formation bands generally vary from laminae to one foot widths but most fall in the one inch to five inch range.
Iron formation bands have a high frequency of small drngfolds.Individual bands are usually highly discontinuous?, bifurcate abruptly, and often have an elongated lens-shaped appearance. A near vertical dip remains uniform throughout the grid.
It is interesting to note that the glacially-scoured bedrock hasbands of iron formation standing in relief and forming rounded crests in miniature roche moutonnee structures.
CONCLUSIONS
Iron formation bands comprise a minor ^10^) percent of the rock types present in the area covered by the ground magnetometer survey.
