Donner Minerals Ltd.: Rainbow Results, New Ground Staked.

VANCOUVER, British Columbia -- Harvey Keats, President of Donner Minerals Ltd. (TSX VENTURE:DML) (FRANKFURT:DNL), provides results for the recently completed 2004 exploration program on the Rainbow Project, located in Nunavut.

A total of 1,012 metres of NQ drilling in six holes were drilled during the 2004 program. Four holes intersected disseminated magmatic sulphides with nickel grades less than 0.5%.

One hole, RB-04 intersected 13.10 grams/tonne gold over 2.14 metres, including 24.20 grams/tonne gold over 1.00 metre, associated with 10 - 15% sulphide stringers and silicifiction at the base of a mafic volcanic unit. Attached to this news release is a table with details of the holes drilled in the 2004 program.

Regional surface sampling in follow-up of the GeoTEM survey returned the following results for both gold and nickel.

One semi-massive sulphide boulder was collected in the vicinity of a sulphide iron formation and area of quartz veining at UTM  coordinates 6801599N and 507577E. The boulder assayed 1.35 grams/tonne gold.

One sample from oxide iron formation in outcrop, with minor pyrite and pyrrhotite mineralization, was collected near the contact with an ultramafic volcanic unit. The sample, located at UTM coordinates 6800828N 508014E, assayed 3.39 grams/tonne gold.

One sample of oxide iron formation in outcrop, with fine dark bands of magnetite, trace sulphide and minor biotite, chlorite and quartz, was collected 17 kilometres northeast of the original Rainbow claims. The sample, located at UTM coordinates 6814487N and 532212E, assayed 26.5 grams/tonne gold. A geological field duplicate sample assayed 18.25 grams/tonne gold.

Fifteen boulder samples were taken from the Rainbow Main Zone area, the site of previously discovered anomalous nickel grade boulders and outcrop, centered around UTM 506235mE, 6801461mN. Five massive sulphide samples assayed from 1.93% to 2.23% nickel, 0.25% to 0.27% copper and 30.1% to 37.4% sulphur. Ten disseminated to net textured sulphide samples assayed from 0.38% to 0.67% nickel, 0.08% to 0.10% copper and 5.54% to 9.71% sulphur.

The Company and Falconbridge Limited have recently staked 15 contiguous claim blocks totalling approximately 145 square kilometres adjacent to the original Rainbow claims as a result of the gold values in drill core and surface samples described above. The new claims cover the oxide iron formation described above as well as other potential target areas. There has been sporadic exploration for gold in the area over the past 50 years and there is evidence of some historical drilling near the oxide iron formation outcrop covered by the new claims.

The Company and Falconbridge are currently reviewing all of the data on the Rainbow Project before a decision is made with respect to conducting further nickel exploration on the Property. All available regional data will be reviewed in order to formulate a gold exploration plan.

Pursuant to an Option and Joint Venture Agreement dated June 18, 2004, the Company has the right to earn a 50% interest in the Rainbow Project from Falconbridge Limited.

Readers of this news release are cautioned that the attachment includes a description of core length and not of true widths, although the core lengths are interpreted to be approximately equal to the true widths.

Falconbridge Limited is the operator of the Rainbow Project and is responsible for the sampling and submittal of samples for assay. Assaying of 2004 samples reported in this news release was carried out and certified by ALS Chemex of Vancouver, BC. Nickel, copper and cobalt were determined by atomic absorption spectometry and platinum, palladium and gold were determined by lead fire assay, inductive-coupled plasma source and atomic absorption finish. Sulphur was determined by a leuco furnace method. Gold samples were fire assayed with a gravimetric finish. Nic Fenner is the Falconbridge Qualified Person and Kerry Sparkes is the Qualified Person responsible for this new release.
