VANCOUVER, British Columbia--(BUSINESS WIRE)--March 7, 2002

Gold Canyon Resources Inc. (CDNX CDNX

See Canadian Venture Exchange (CDNX).
:GCU) (the "Company") is pleased to confirm that, as previously announced, certain Rare Earth Elements (REE's) are present in anomalous to highly anomalous amounts at the Company's Cordero Gallium Project, Nevada. The REE's cerium cerium (sēr`ēəm) [from the asteroid Ceres], metallic chemical element; symbol Ce; at. no. 58; at. wt. 140.12; m.p. 799°C;; b.p. 3,426°C;; sp. gr. 6.77 at 25°C;; valence +3 or +4. , neodymium neodymium (nē'ōdĭm`ēəm), metallic chemical element; symbol Nd; at. no. 60; at. wt. 144.24; m.p. about 1,021°C;; b.p. about 3,068°C;; sp. gr. 7.004 at 20°C;; valence +3.

Samarium is a lustrous silver-white metal. , holmium, erbium, ytterbium ytterbium (ĭtûr`bēəm) [for Ytterby, a town in Sweden], metallic chemical element; symbol Yb; at. no. 70; at. wt. 173.04; m.p. 819°C;; b.p. about 1,194°C;; sp. gr. about 7.0; valence +2 or +3. , lutetium lutetium, formerly lutecium (both: ltē`shēəm), metallic chemical element; symbol Lu; atomic number 71; at. wt. 174.967; m.p. about 1,663°C;; b.p.  and thulium thulium (th`lēəm) [from Thule, an ancient name for Scandinavia], metallic chemical element; symbol Tm; at. no. 69; at. wt. 168.9342; m.p. about 1,545°C;; b.p.  show weak positive anomalies in approximately 20% of the gallium intervals examined.

The length weighted average concentrations of REE's which exhibit a positive association with gallium for previously reported, second order included drill intercepts, (those intercepts generally exceeding 50 grams gallium per Metric Tonne) is summarized below in Table 1:

REE's and other elements occurring in spatial association with the gallium represent potential by-product or co-products, with potential to add incremental value to the project if these elements can be economically recovered and marketed. At this time, however, there can be no assurance given that the Company will be able to extract or refine economically any of these elements associated with the gallium, or that the Company will be able to market successfully these metals if extracted.

Sample Chain of Custody The movement and location of physical evidence from the time it is obtained until the time it is presented in court.

Judges in bench trials and jurors in jury trials are obligated to decide cases on the evidence that is presented to them in court.
, Preparation and Analysis

All drill samples represent five foot drill intervals. Drilling was reverse circulation (RC) type drilling, completed with an MPD MPD maximum permissible dose.

 1000 track mounted RC drill, manufactured by Drill Systems of Canada. The drill was owned and operated by Drift Exploration of High River, Alberta High River is a town in southwestern Alberta, Canada with a population of 10,716. (2006). It is  km ( mi) south of the city of Calgary, at the junction of Alberta Highways 2 and 23. , Canada. All samples were collected by the drilling contractors personnel under the supervision of Gold Canyon geologists. These samples were then collected from the drill sites by Inspectorate Rocky Mountain personnel, again under the supervision of Gold Canyon personnel, and transported to Inspectorate Rocky Mountain's Reno laboratory facility. Samples were then dried and stage crushed to 80% minus 10 mesh. A 300 gram sample was then riffle split and pulverized to minus 200 mesh in a ring and puck type pulverizer. Inspectorate's Rocky Mountain Geochemical laboratory in Reno, Nevada, analyzed these pulps for gallium and certain other elements by acid digestion and Inductively Coupled Plasma An inductively coupled plasma (ICP) is a type of plasma source in which the energy is supplied by electrical currents which are produced by electromagnetic induction, that is, by time-varying magnetic fields.  (I.C.P.), at their Reno facility. A representative split of the original pulp was then sent to Inspectorate's New Orleans, La facility for analysis of REE's and certain other Exotic Metals by means of X-ray Floresence (XRF). For the purpose of this study, gallium values obtained by I.C.P. analysis were used to define the intervals examined for potential co-product concentrations of rare earth elements (REE's).

For reference, Table 2 below shows the relative crustal abundance for rare earth elements (REE's) and gallium.
