Aurora Platinum Corp. New High-Grade Cu-Ni-Au-Ag-PGM Mineralization Discovery, Crazy Creek Zone, Foy Offset Property Sudbury, Ontario.Business Editors VANCOUVER, British Columbia--(BUSINESS WIRE)--April 7, 2004 Aurora Platinum Corp. (TSX TSX Toronto Stock Exchange (TSE before April, 2002) TSX Transfer from Stack Pointer to Index TSX True Space Extension VENTURE:ARP) announced today the results of its recent surface exploration program on the Crazy Creek Zone, Foy Offset, Sudbury, Ontario. Mineralization Mineralization The process by which the body uses minerals to build bone structure. Mentioned in: Rickets mineralization, n the bioprecipitation of an inorganic substance. on the Crazy Creek Zone is located along the Foy Offset Dyke, approximately four kilometres west of the Company's Nickel Lake discovery (see News Release dated May 15, 2002).

Aurora has vested in its option agreement with Falconbridge Limited (part of its Foy Joint Venture) and consequently Aurora has acquired 60% of the Foy Joint Venture Claims and 60% of Falconbridge's 50% interest in the Canhorn Claims (see News Release dated August 12, 2003). Past drilling and geophysics (1980's) identified a 600 metre long east trending zone of stacked subhorizontal Cu-Ni-PGM sulphide-rich lenses and veins east of the Crazy Creek Fault. The mineralized zone is defined by geophysics and is characterized by high-grade Cu-PGM rich lenses and veins hosting metal values similar to "footwall-type" mineralization. The zone is open to the east and at depth. Historical drill intersections include the following:

Ground conductivity is an extremely important factor in determining the strength and field propagation of AM radio stations because of mediumwave's groundwave propagation. survey (EM31) was completed over the Zone in 2003 to determine if the intersected mineralization outcrops on surface, to better define the extents of the near surface mineralization and to help constrain the planned trenching program. By late fall 2003, an extensive program of surface stripping, trenching, and outcrop washing was completed. The resulting work exposed several new areas within the offset dyke hosting abundant chalcopyrite-bornite rich veins and stringers, and has established that the mineralization exists from surface to approximately 250 metres vertical depth (the deepest historical intersections) and extends along strike to the east for 600 metres. The Crazy Creek Zone remains open in all directions. An initial six grab samples, taken of some of the veins from the trenched area, returned assays up to 7.47 grams per tonne gold plus platinum plus palladium and 123 grams per tonne silver. Detailed mapping and channel sampling of the trenched areas is now complete, and has confirmed that the mineralization is related to a late hydrothermal hydrothermal, hydrothermic relating to the temperature effects of water, as in hot baths. event, with veining vein·ing n.

This new Cu-Ni-PGM discovery, being related to a relatively low temperature (approximately 400 degrees C) hydrothermal process, constitutes a new type of mineralization within the offset dyke environment. At Crazy Creek the Foy Offset Dyke consists of an inclusion bearing phase (principally granitic gneiss gneiss (nīs), coarse-grained, imperfectly foliated, or layered, metamorphic rock. Gneiss is characterized by alternating light and dark bands differing in mineral composition and having coarser grains than those of schist. and diabase diabase: see basalt. diabase or dolerite Fine- to medium-grained, dark gray to black intrusive igneous rock. Diabase is one of the dark rocks known commercially as “black granite. within the quartz diorite Quartz diorite is an igneous, plutonic (intrusive) rock, of felsic composition, with phaneritic texture.

Samples were taken to establish both the metal content of the veins and the host rock - the inclusion bearing quartz diorite. Channel sample lengths varied from 15 centimetres to 2 metres, and sample widths from less than 1 centimetre to 9 centimetres. Gold values vary from detection limit (less than 1 part per billion) to 15.2 grams per tonne, platinum is reported from less than 5 parts per billion to 3.6 grams per tonne, palladium from less than 1 part per billion to 7.5 grams per tonne, silver from detection limit (less than 0.2 parts per million parts per million mg/kg or ml/l; see ppm. ) to 217 grams per tonne, copper from 0.01% to 33.9%, and nickel from 0.01% to 4.3%.

Intense iron-rich chlorite chlorite Widespread group of layer silicate minerals composed of hydrous aluminum silicates, usually of magnesium and iron. The name, from the Greek for “green,” refers to chlorite's typical colour. alteration envelopes occur along vein margins and in places this pervasive hydrothermal alteration imparts a distinctive black colour to the host quartz diorite. Remobilised Cu-PGM rich mineralization in the Sudbury camp is often spatially related to typical contact and offset type Ni-Cu massive sulphide deposits. This association has yet to be identified at Crazy Creek and remains a primary focus for future exploration programs. Planning for the next phase of exploration is in progress and will include surface geophysics followed by a drill program to further evaluate the economic viability of the Crazy Creek vein/stockwork mineralization and to search for associated Ni-Cu rich massive sulphide mineralization. The Crazy Creek program is being supervised by Yves Clement (P.Geo), the Qualified Person for this project. Aurora Platinum Corp. is actively exploring for Ni-Cu-PGM deposits in Ontario and Quebec. The Company has an option/joint venture with Falconbridge Limited in the Sudbury District (Foy and Footwall foot·wall n. Geology 1. The mass of rock underlying a mineral deposit in a mine. 2.
