The Open File government report, is entitled "Bonanza-grade gold from Neoproterozoic low-sulphidation epithermal veins and breccias, Bergs prospect, Avalon Zone, Eastern Newfoundland." The following is an extract from that report. "Recent mapping and lithogeochemical sampling of the Late Neoproterozoic epithermal veins and breccias at the Bergs Prospect (Manuels area, Avalon Peninsula) has documented the first example of bonanza-grade, low-sulphidation gold mineralization Mineralization The process by which the body uses minerals to build bone structure.

Reaching out in several directions: a multidirectional campaign. 2. , crustiform-banded silica-hematite veins and vein-breccia that intrude silica-altered rhyolite rhyolite, fine-grained light-colored acidic volcanic rock. Rhyolite is chemically the equivalent of granite, and is thus composed primarily of quartz and orthoclase feldspar with subordinate amounts of plagioclase feldspar, biotite mica, amphiboles, and pyroxenes. and rhyolite breccia breccia: see conglomerate. breccia Coarse sedimentary rock consisting of angular or nearly angular fragments larger than 0.08 in. (2 mm). Breccia commonly results from processes such as landslides or geologic faulting, in which rocks are fractured. in outcrop in the central part of the Bergs Prospect yielded the following high-grade gold assays: 54.30 g/mt, 26.50g/mt, and 23.60g/mt; a replicate analysis of the pulp of the 54.3 g/mt Au assayed 45.9g/t Au. Other veins in the same outcrop assayed 4.9 g/t, 1.65 g/mt, 0.34g/mt, 0.27g/mt, 0 .14g/mt and less than7ppb g/mt (detection limit). Four of five grab samples of banded vein fragments collected from subcropping angular breccia located ca. 85 m to the northwest of the high-grade gold veins contain anomalous gold: 7.75 g/mt, 5.41g/mt, 4.87 g/mt, 2.06 g/mt." The report concludes: "The low-sulphidation veins and breccias of the Bergs Prospect are examples of widespread, robust, well-preserved systems characterized by variably anomalous gold content and discrete zones of multi-gram gold concentrations. New data presented above: i) prove the hypothesis that these Neoproterozoic low-sulphidation veins should contain bonanza-grade concentrations of gold, ii) indicate that highly prospective crustal levels are preserved in these Neoproterozoic systems, and iii) underscore the importance of high density sampling in prospecting within these systems." Rubicon controls a 45 kilometre long district scale land position at Avalon which covers other known epithermal gold occurrences documented by Rubicon and others (see news release dated October 30, 2003 and Company website at www.rubiconminerals.com) and is pleased to learn of encouraging results from this independent source. Rubicon acknowledges the continuing work done by the Sean O'Brien of the Geological Survey in documenting this well preserved gold-bearing epithermal system.
