Primary Commodities: Gold
Township or Area: Coltham
Latitude: 49° 39' 10.38" Longitude: -86° 45' 24.65"
UTM Zone: 16 Easting: 517551.139 Northing: 5500066.138 UTM Datum: NAD83
Resident Geologist District: Thunder Bay North
NTS Grid: 42E10NW
Point Location Description: Trenches and diamond drill holes.
Location Method: Conversion from MDI
Access Description: The claim is located in north central Coltham Township. Follow Highway 11 for 9.5 km east of the turn-off to Geraldton (Hwy 584) and southeast on Eldee Lake Road for about 4.8 km to the east-west baseline which crosses the property. The occurrence is located approximately 1.4 km east along the baseline and is less than 137 m to the south.
1934: The claim covering the occurrence was staked by E.M. Howells (TB 13316). Surface exploration was performed. 1935-37: Surface exploration and trenching was completed. 1939: The claim was optioned to J.E. Greenburgh. Magnetometer and geological surveys were conducted, followed by trenching and diamond-drilling. One hole was drilled to test the occurrence (Drill Hole No. 11). 1941: Extensive stripping and trenching continued. 1942: J.E. Greenburgh patented the claim. 1983: The property was restaked by Michael Malouf of Quaternary Mining and Exploration Company Ltd. 1984: A grid was cut on which magnetometer and EM surveys were conducted. Geraldton Longlac Gold Inc. was formed by Michael Malouf and all claims covering the Burroughs occurrences were transferred to this new company. 1987: Geraldton Longlac Gold Inc. conducted an extensive overburden stripping program, primarily in an area between Burroughs Central and Burroughs East occurrences (claim TB 677042). Diamond drilling was also undertaken. 2000: Geraldton Longlac Gold Inc. holds a large block of leased claims, of which 4 cover the three historic Burroughs occurrences. Burroughs Syndicate Occurrence (West) is located on leased mining claim TB 677040.

Dec 07, 2005 (G White) - The Burroughs Syndicate occurrence (West) is located in the southeastern portion of the main Beardmore-Geraldton metasedimentary-metavolcanic belt. The Croll Lake stock is situated immediately north of the occurrence and is postulated to be the heat source for much of the gold mineralization in the Geraldton camp. The three Burroughs occurrences (West, Central, and East) lie within the eastern portion of what is termed the 'Barton Bay Deformation Zone' (Macdonald 1983). This is a lithotectonic package which is up to 5 km wide, is associated with the Bankfield-Tombill fault in the Geraldton area (Lavigne 1983, Buck and Williams 1984). The deformation zone is defined by anastomosing shear zones with intervening areas of less deformed rocks. Just east of the Burroughs occurrences, the Barton Bay Deformation Zone is well exposed along the west shore of Long Lake where simple shear strain indicators are found over a 2 km width. This deformation zone continues east of Long Lake and studies indicate that it may be up to 4 km wide along the east shore.
Dec 07, 2005 (B Nelson) - The property is underlain by Timiskaming sediments and basic to intermediate metavolcanic units wrapped around the southern flank of a large granite pluton. The Keewatin volcanic rocks in the southern belt consist mainly of chloritic tuffs and breccias. They appear to be related to the units found southeast of the MacLeod -Cockshutt and Hard Rock Mines and lie stratigraphically above the massive andesite and basalt flow rocks. Shearing and metamorphism obliterate much of the primary pillow structures. Mineral assemblages are high in amphibole, chlorite, epidote, carbonate and biotite. The iron formation marks the north limb of a major syncline, but Archibald (1983) believes the units described above form part of the southern limit of an overturned synclinal structure. He also believes that the property lies along the extension of the Bankfield-Tombill strike fault which is expresses as shearing in the units found on the property. To the east, quartz porphyry intrusions are intercalated with iron formations and conglomerates. The gold values were obtained in quartz-chlorite veins mineralized with disseminated pyrite.

Dec 07, 2005 (B Nelson) - Tuffs, agglomerates and lenses of greywacke are found interflowed with the volcanic sequences. These units generally strike east-west and dip steeply to the south. The volcanics lie disconformably below the sediments which also strike east-west and dip 75 degrees south.

Dec 07, 2005 (B Nelson) - Gold values were obtained in quart-chlorite veins mineralized with disseminated pyrite. The following intersections are from J.E. Greenburgh (1939) hole #11: Sample 75 ran 0.26 oz/ton Au over 6.1 cm. Sample 76 ran 0.14 oz/ton au over 6.1 cm. It should be noted that the Burrough's drilling was done with an x-ray drill which could not penetrate heavy overburden. For this reason, some showings were not explored along strike and geophysical anomalies were not tested at these locations.
