Exploration History

1933-34: Gold Eagle Syndicate acquires property, does surface exploration-trenching and diamond drilling. 1934-35: Gold Eagle Mines is incorporated, sinks shaft to 157.5 m and levels established at 37.5, 75, 112.5, and 150 m. 1937: Mill brought into production. 1938: An inclined winze from the 150 m level down to the 219 m level is established, and levels at 180 and 210 m are established. 1939: Winze is deepened to 300 m, and levels established at 255 and 300 m. 1946: Surface diamond drilling is completed. 1958: 15 diamond drill holes are completed totalling 2912 m. 1960-1963: Name changed to Goldray Mines Ltd., drills 2 diamond drill holes totalling 1562 m. 1976: Name changes to Canray Resources Ltd. 1983: Company changes name to Exall Resources Ltd. 2002: Southern Star Resources Inc. signed an option to acquire a 50% interest in the Gold Eagle property. 2003: Southern Star conducted line cutting, geophysical surveys including IP, resistivity, magnetometer and VLF-EM, geochemical soil surveys, geological mapping and prospecting, and drilling 8 DDH totalling 4,399 m. The drilling program resulted in the discovery of the Western Discovery Zone. 2004: Southern Star drilled 27 DDH totalling 15,868.5 m. 2005-6: Southern Star drilled 16 DDH totalling 14,264 m on the Bruce Channel and West Discovery Zone. In September 2006, Exall and Southern Star merged to form Gold Eagle Mines Ltd. 2007: Gold Eagle Mines conducted exploration programs on the property. 2008: Goldcorp acquired property. 2012: Goldcorp drilled 13 DDH, totalling 6378 m.

Geology Comments

Jan 29, 2015 (Therese Pettigrew) - The Red Lake greenstone belt is situated in the western portion of the Uchi subprovince. The Uchi subprovince is a typical Archean granite-greenstone terrain containing linear eastward-trending belts of volcanic and sedimentary rocks and synvolcanic intrusions, which are intruded by younger granitoid plutons and batholiths. The supracrustal rocks of the Red Lake greenstone belt represent discrete magmatic and erosional events over a period of approximately 270 m.y. between 3,000 and 2,730 Ma. The supracrustal rocks were folded and subsequently intruded by felsic intrusive rocks which formed during a period of plutonism spanning 30 m.y. The McKenzie stock and the Dome stock occur internally within the Red Lake greenstone belt and are both overprinted by hydrothermally altered zones hosting several past-producing gold mines. The Gold Eagle mine property is divided into two parts by a regional unconformity between the McNeely Sub-assemblage to the west and the Bruce Channel Assemblage which dips into the property at depth from the east. The McNeely Sub-assemblage includes clastic sediments and felsic pyroclastic rocks, while the Bruce Channel Assemblage includes chemical sediments, clastic sediments and felsic pyroclastic rocks. The unconformity is intruded by the McKenzie Stock, which is a zoned intrusion of intermediate to felsic composition. The gold mineralization at the past-producing Gold Eagle Mine lies within the southern part of the McKenzie Stock and is partly hosted within the intrusion or in a large inclusion of metasedimentary rocks (2004 NI 43-101 Report).

Mineralization

Mineralization Comments

Mar 19, 2012 (A McKee) - The Western Discovery Zone is located approx 500 m west of the Gold Eagle Mine. Iti s interpreted to occur as a series of sub-parallel, quartz-rich veinlets that are hosted by intrusive rocks of the McKenzie Stock. The colour of the quartz varies from translucent through dark grey to milky white and cross cutting textural relationships in some of the larger veins suggest that the different colours of quartz represent different episodes of veining. Gold values do not appear to demonstrate any correlation with the different colours of quartz veinlets. Visible gold is commonly observed to be hosted by the quartz veinlets. Anomalous gold values above approximately 100 ppb are typically found in association with the sericiticall altered and veined intervals. The mineral resources are found in the “Technical Report on the Resources estimate of the Gold Mineralization found on the Western Discovery Zone of the Gold Eagle Mine Property, Red Lake Ontario, NTS 52 N/4. November 2004”

Jan 29, 2015 (Therese Pettigrew) - The Western Discovery Zone is composed of five pods of geochemically anomalous gold values have defined the gold mineralization along a distance of 490 metres in an east-west direction, a distance of 370 metres in a north-south direction, and along a height of 230 metres. The orientation of the Western Discovery Zone is found to have an overall strike of approximately 060°, a dip of approximately 15° to the southeast, and to have a plunge of approximately 15° to azimuth 240° (2004 NI-43-101 Report). Assays during the 2004 drilling program ranged from 1 g/t to 411.39 g/t Au (OFR6146 p. 32). Significant assays from the 2005 drill program ranged from 4.96 g/t to 295.0 g/t Au (OFR6180 p. 26).
