Mineral Results

RockBridge has completed its fall soil sampling program within the 100% ownership in 9 claims covering approx 4,680 acres of quartz claims in the White Gold District of the central Yukon. The claims are in the vicinity of the previously announced discovery (May 27, 2009) by Underworld Resources (UW.V) that stated significant results returning grades of 3.94 g/t Au over 59.9 metres and 3.59 g/t Au over 98.3 metres. Equity Exploration Consultants Ltd. (Equity) completed the sampling program and has found "there are several significant highs of Au (gold) and Mo (Molybdenum), and the entire escarpment shows minor anomalous levels of Au, As (Arsenic), Sb (Antimony) and Mo unevenly distributed over an area of 3 km x 2km.". Equity concludes that these anomalies are worthy of further exploration.

RockBridge has completed its fall drilling program on the Newfoundland Cross Hills property. Prospecting programs earlier this year encountered Copper of up to 1.95%, and Total Rare Earth Oxides of up to 1.11% from outcrop samples. Historic assays have returned values up to 2.2% Zr (Zirconium), 0.33% Y (Yttrium), 0.26% Nb (Niobium), 0.17% Ce (Cerium), 0.08% Th (Thorium) and 0.03% Sn (Tin). The fall program consisted of 4 diamond drill holes totalling 387m in the zone prospective for copper, and 2 diamond drill holes totalling 196m in the zone prospective for Rare Earths. The copper zone did not intersect any significant mineralization at depth, while the Rare Earth showings that were drilled showed anomalous values Yttrium plus Total Rare Earth Oxides.

RockBridge President, Adrian Van de Mosselaer, stated, "The Cross Hills Rare Earth property remains highly prospective and favourable geologic environment which has returned some very interesting historic, prospecting and drill results. We look forward to seeing this more than 20,000 acre property more fully explored in the future. Our current focus is on the expansion of our Oil and Gas assets and the commencement of horizontal drilling on RockBridge's Cardium property which will be generating significant value growth for our shareholders as this property is exploited."
