Report of the Helicopter-borne Time Domain Electromagnetic Geophysical Survey, Vanguard Property, Kashabowie Area, Thunder Bay Area, Ontario, for Canadian Golden Dragon Resources Ltd, by Geotech Ltd. Claim Map Scale 1:50,000, Approximate Reduced Total Field Magnetic Map Scale 1:40,000, Approximate Reduced Airborne EM Profiles Scale 1:40,000, Approximate In Pocket Airborne EM Profile Map Scale 1:20,000 Airborne Magnetic Contour Map Scale 1:20,000 SUMMARY Canadian Golden Dragon Resources Ltd, holds several groups of claims, including the 320 claim units in 47 claims within the Kashabowie area within the Shebandowan greenstone belt, about 88 km WNW of Thunder Bay, Ontario. This report deals with the recent airborne geophysical survey over the Vanguard claims group. On February 11 th to 12th Geotech Ltd flew the Vanguard property with the Helicopter-borne time domain electromagnetic/ magnetic survey system. This survey was intended to outline electromagnetic conductors and to obtain detail magnetic information for the purpose of outlining the subsurface geology. Results of the survey are appended as maps. INTRODUCTION Recently Canadian Golden Dragon Resources has been directing its attention to greenstone belts in addition to its interest in ultramafic intrusives. The Kashabowie area is in the Shebandowan greenstone belt in the Wawa subprovince. The Archean age Superior Province includes several greenstone belts with iron formations and sulphide occurrencies, many with economic basemetal mineralization. Although the greenstone belts have been subject to exploration for many years, newer geophysical techniques have improved the discrimination of conductive features as well as providing a better depth penetration. Although helicopter borne geophysical surveys have been used for many years, they have been based on frequency domain systems which have limited depth penetration, although generally resolution of near surface features have been good. The move to time domain electromagnetic systems began in the 1960©s with the Barringer Research INPUT system. INPUT improved depth penetration, although resolution was less. Several time domain systems have been developed since, among them the Fugro (formerly Geoterrex) Megatem system with high power and very good depth penetration. Recently Geotech Ltd has developed and tested the helicopter borne Dream Catcher Time Domain Electromagnetic system. Test flights by Megatem and Dream Catcher TDEM have shown comparable depth penetrations but better lateral resolution for the latter. Canadian Golden Dragon decided to use the Dream Catcher TDEM system for a detail look at the Kashabowie area of the Shebandowan greenstone belt. LOCATION AND ACCESS The Vanguard property is road accessible via Hwy 11 to Kashabowie situated ~88 km WNW of Thunder Bay. Local and forestry roads branch off the highway south to the property.

The age is Archean. The Shebandowan greenstone belt is arcuate in shape reflecting the curvature of the Quetico - Shebandowan greenstone belt boundary, approximately WSW - ENE as shown by the magnetic trends. The Shebandowan greenstone belt is subdivided into the Burchell and Greenwater assemblages, with a third suite of rocks, the Shebandowan assemblage, consisting of sedimentary and volcanic rocks which overlie unconformably the Burchell - Greenwater boundary, locally straddling it. The Burchell assemblage is divided into three cycles, with cycle 1 intruded by the Shebandowan Lake intrusion. The lower part of cycle 1 comprises massive basalt flows locally altered to chlorite schist. Pillow lava underlies the dacite and rhyolithic units in the upper parts of the cycle. Near the base of this cycle are tabular, serpentinized, peridotite units that contain copper - nickel mineralization. Cycle 1 contains the most extensive basic intrusions in the greenstone belt. Cycle 2 also contains numerous mafic intrusions, but also distinguished by a thick unit of rhyolite to dacite which extends along the northern part of the belt. The main mass of this felsic unit located in and south of the Burchell area is displaced and separated from the more tuffaceous eastern part by right-handed transcurrent movement on the Crayfish Creek fault. (The geology information has been abstracted from "Geology of Ontario; OGS Special Volume 4, Pt1, 1991.) Appended is a two-page table: Table 12.5. Metamorphic mineral assemblages of the Shebandowan greenstone belt. Geology of Ontario; OGS Special Volume 4. Numerous mineral occurrencies have been found on the property. AIRBORNE TIME DOMAIN MAGNETIC - ELECTROMAGNETIC SURVEY On February 11th to 12th, 2003, a helicopter borne geophysical survey was flown over the property with a newly developed time domain electromagnetic system named "Dream Catcher TDEM system". A total of 527.7 km as flown, some of it outside the claims for operational purposes as well to keep the boundaries of flying area manageable. Navigation was by GPS and radar altimetry. The flying height was maintained at 80 m above ground, with sensor at 35 m above ground, and aircraft velocity was nominally 70 km/hour. The low altitude of the sensor and relatively slow speed of he aircraft, coupled with the superior depth penetration and sensitivity of a time domain electromagnetic system has produced survey results where closely located conductors have been discriminated.
