Report on Ground Magnetometer Survey on Blackwell and Durham Properties 1.0 Introduction The Blackwell and Durham properties are located in Blackwell and Laurie Townships, 55 kilometres west of Thunder Bay, Ontario and represent an exploration target for gold mineralization. From September to October 1996 and during March 1997, Avalon Ventures Ltd. conducted a exploration program of linecutting and magnetometer surveying as part of a larger exploration program on the Blackwell and Durham properties. The purpose of this report is to document and interpret the results of the magnetometer survey and to propose an appropriate program for further exploration. 2.0 Location and Access The properties are located in southeastern Blackwell Township and northeastern Laurie Township approximately 55 kilometres west northwest of the city of Thunder Bay, Ontario (Figure 1). The NTS reference for the claims is 52 A 12 SW, with the property centered at Latitude 48036© Longitude 89G55©. The junctions of Highways 17 and 11 occurs along the eastern boundary of the properties. Access to the property area is excellent, as shown in Figure 2. It is best achieved by travelling west from Thunder Bay along Trans Canada Highway 17 to the junction of Highway 11, 0.5 kilometres west of Shabaqua, Ontario. From this point, Highway 11 leads westward and crosses the central portion of the property from which several bush roads provide additional access to various parts of the property. The southern portion of the property is reached by travelling westward on a dirt road which leaves Highway 17 across from the motel/restaurant at Shabaqua Corners and provides bridge access across the Shebandowan River. From this point, several new logging roads lead to various portions of the southern half of the property. 3.0 Disposition The Blackwell and Durham properties are contiguous properties subject to two separate underlying agreements but have been pooled together for exploratory purposes. With the exception of claim TB 1206676 of the Durham property, the claims occur in the southeastern portion of Blackwell Township, and are found on claim sheet G-644. Claim TB 1206676 occurs in the northeast corner of Laurie Township, contiguous to the south boundary of claim TB 1206677 and is found on claim sheet G-669. The claims are in good standing and are on record at the office of the Thunder Bay Mining Recorder in Thunder Bay, Ontario. September 10, 1997 Avalon Ventures Ltd.

Green Ice funded the current work program and can earn a 509fc interest in the properties by making cash and share issuances to Avalon, and by performing exploration work on the properties over 4 years. Avalon is the operator of the work program until Green Ice Corporation has vested its interest. 4.0 Previous Exploration A review of assessment files for the area indicates that there has been little previous exploration work on the area covered by the Blackwell and Durham properties. Documented previous work is as follows: 1925: T.L. Tanton conducted a regional mapping survey for the Department of Mines. 1975- Noranda conducted airborne EM, geological mapping, ground magnetic, 1979: electro-magnetic and gravity surveys over part of the southern part of the property. 1982: Lacana conducted reconnaissance geological mapping over the southern part of the property.

Ground surveys included reconnaissance mapping and soil sampling on north-south claim lines (400 m spacing). Anomalous gold in humus was identified in the central part of the property. 1990: M.W. Carter conducted regional mapping survey for the Ontario Geological Survey, the results of which are documented in OFR 5727 entitled The Geology of Blackwell and Laurie Townships. 1990: The Shebandowan Greenstone Belt, including the subject property, was flown by the Ontario Geological Survey utilizing the Aerodat Magnetic/ Electromagnetic System. Several moderate to strong EM anomalies were detected, occurring within the current property boundaries. 5.0 Regional Geology The Blackwell and Durham properties lie within the western extension of the Abitibi-Wawa- Shebandowan subprovince of the Superior structural province of the Canadian Shield. The volcanic-sedimentary units of this belt are bounded to the south by granitic terrain and to the north by the Quetico subprovince (Figure 3). The volcanic-sedimentary stratigraphy can be subdivided into the Burchell and Greenwater assemblages of Keewatin-age (2710-2722 Ma), and the Shebandowan assemblage of Timiskaming-age (2689-2696 Ma). The Burchell and Greenwater assemblages are interpreted to have island arc and oceanic crustal origins, while the volcanic rocks of the Shebandowan assemblage are interpreted to be derived from mantle sources. The Burchell assemblage occurs to the north, is essentially homoclinal and youngs to the north while the Greenwater assemblage occurs to the south of the Burchell assemblage and faces to the south. The Shebandowan assemblage (herein called ©Timiskaming©) is comprised of alluvial- fluviatile sediments, alkaline volcanics and associated alkaline intrusives. The Timiskaming units occupy two east-west trending fault bounded basins, as shown in Figure 3. The Timiskaming rocks include an assemblage of predominantly fluviatile metasediments with lesser amounts of intercalated shoshonitic intermediate to mafic metavolcanic rocks. The unconformity defining the southern contact of the Timiskaming belt with the older Keewatin volcanic assemblage lies just south of the property.
