Geochemical sampling at Target 5 consists of about 150 surface samples of outcrop and float. Sampling results are similar to those at the Original Zone where gold, silver, arsenic, antimony, and molybdenum are anomalous. Target 5 surface samples contain gold (ranging from 0-1.08 g/t gold), silver (ranging from 0-99 g/t silver), arsenic (ranging from 0-464 ppm), antimony (ranging from 0-240 ppm), and molybdenum (ranging from 0-69 ppm).

² The historical resource estimate for the Castle gold project was completed by James D. Greybeck, Senior Geologist for Cordex Exploration Co. in April, 1999, under the direction of Andy B. Wallace, then Manager of Cordex Exploration Co. and Vice President of Rayrock Mines, Inc. This report and data used in its preparation has been recently reviewed by Andy B. Wallace for the purpose of this press release under his obligations a Qualified Person for Columbus Gold (US) Corp. Drill data used for Greybeck's report was from Cordex Exploration Co., Kennecott Exploration, Houston Oil and Minerals, Falcon Exploration, and Mintek Resources which data is on file in the offices of Cordex Exploration Co. The data is judged relevant and reliable by Andy B. Wallace. The resource was termed a "Geologic Resource" at the time of Greybeck's report, which was in line with current practice for the time. Greybeck prepared geological cross sections and calculated the resource by hand, using a polygonal method with a lower cut-off of .005 opt Au (0.17 g/t Au). Where drilling was closely spaced gold values were interpolated between cross sections using weighted averages projected 50 feet on either side of the cross section. Columbus plans additional drilling to confirm Greybeck's interpretations and to fill in gaps in the drilling. A qualified person has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves. The Company is not treating the historical estimate as current mineral resources or mineral reserves.
