Donner Minerals Ltd: Preliminary Results From Stephens Lake.Business Editors VANCOUVER, British Columbia--(BUSINESS WIRE)--April 8, 2003 Mr. Harvey Keats, President of Donner Minerals Ltd., announces that three holes, totalling 992 metres, have been drilled in the initial phase of the 2003 Stephens Lake exploration program. Significantly, one of the holes intersected 72 metres of sulphide iron formation, a key ingredient in the Thompson Nickel Belt
Nickel Belt is an informal nickname for the Sudbury region in Northern Ontario, because of the belt of nickel ore deposits found in the area. model. The other key ingredient, ultramafic rocks Ultramafic (or ultrabasic) rocks are igneous and meta-igneous rocks with very low silica content (less than 45%), generally >18% MgO, high FeO, low potassium, and are composed of usually greater than 90% mafic minerals (dark colored, high magnesium and iron content). , was intersected in early 2002 by a previous owner exploring for diamonds on ground that is now part of the Stephens Lake Project. The sulphide iron formation intersection has been sampled and assays are pending. However, nickel and copper assays are not expected to be significant. The discovery of sulphide iron formation and the occurrence of ultramafic rocks on the property reinforces the interpretation that the Stephens Lake Belt is the extension of the Thompson Nickel Belt, and confirms the potential for nickel sulphide deposits similar to Thompson. The EM conductors in the other two holes were explained by the intersection of graphitic sediments. There are no other holes currently planned in this phase. All three holes were drilled on targets identified by an airborne GEOTEM survey and verified by ground magnetic and electromagnetic surveys in 2002. The holes were widely spaced over a 50 kilometre strike length of the Stephens Lake Belt and were drilled on separate geophysical ge·o·phys·ics n.

The deposits in the Thompson Nickel Belt occur where ultramafic rocks interact with sulphide iron formation. The ultramafic rocks provide the nickel and the sulphide iron formation provides the sulphur required to form the nickel sulphide deposits in the Thompson model. Falconbridge has arranged for a Thompson Nickel Belt expert from the Manitoba Geological Survey The term geological survey can be used to describe both the conduct of a survey for geological purposes and an institution holding geological information. A geological survey to examine all of the drill core from the 2003 drill program and all of the core from the 2002 drill program where the ultramafic rocks were intersected. The stratigraphy stratigraphy, branch of geology specifically concerned with the arrangement of layered rocks (see stratification). Stratigraphy is based on the law of superposition, which states that in a normal sequence of rock layers the youngest is on top and the oldest on the intersected at Stephens Lake will be compared with the stratigraphy which hosts the Thompson deposits. The examination is expected to occur in late April or early May. A follow-up 2003 program will be designed after all of the available information on the property is reviewed.
