Red Eagle Mining (RD.V) Intercepts 47.4 Metres Commencing From Surface at 1.34 Grams Gold Per Tonne in Oxides at Santa Rosa
VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 4, 2012) -Red Eagle Mining Corporation (TSX VENTURE:RD)(OTCQX:RDEMF) is pleased to announce that the initial assay results have been received from the Phase Three oxide core drill programme at the San Ramon gold system located within the Santa Rosa gold project in Colombia. Highlights from the initial holes (SR-066 to SR-076) include intercepts in hole SR-072 of 47.4 metres commencing from surface at 1.34 grams gold per tonne and in hole SR-069 of 11.7 metres at 4.96 grams gold per tonne. These latest results confirm strong gold mineralisation from surface in the oxidised material.

"Our ongoing Phase Three oxide delineation drilling and metallurgical testwork results at San Ramon are confirming the open pit conventional heap leach potential of San Ramon," comments Ian Slater, Chief Executive Officer. "The metallurgical programme to date has given heap leach recoveries of 73% to 85% from this material."
The San Ramon structure trends east-west, dips 60°-70° to the north, extends over 1,800m, is up to 60m in width and is mineralised from surface. Phase One and Two drilling intercepts in the primary mineralisation averaged 2.1 g/t Au to a vertical depth of over 250m. The mineralisation continues to be open at depth. The Phase Three 5,000m core drill programme is delineating the oxide mineralisation on 50m centres from surface to the primary mineralisation. 37 holes totaling 2,671m have been completed to date. Assays are pending on 26 holes (SR-077 to SR-102). The work program for the remainder of 2012 includes:
•Preliminary Economic Assessment level metallurgical test work;
•Environmental base line studies;
•NI 43-101 compliant measured and indicated resource report; and
•Preliminary Economic Assessment (to be released in the first half of 2013).
Table 1 summarizes the significant (+0.20 g/t) uncut gold intercepts from Phase Three core drill holes SR-066 to SR-076 (see Figure 1 - Drill Hole Plan and Figure 2 - Long Section). True widths are estimated to be 70-90% of the intercepts and vertical depths are estimated to be 70-90% of the drilled depths reported below. Internal dilution within intercepts is limited to the inclusion of runs of no more than 7m below cut-off. Hole SR-066 did not intercept economic mineralisation.

Quality Control and Assurance (QC/QA)
All drill samples were collected with a diamond core drill rig using approximately one metre sample intervals of whole core and following standard industry practice. Acme Analytical Laboratories prepped and screened samples in Medellin, Colombia and assayed samples in Santiago, Chile. Gold values were determined by fire assay of a 50g charge at 250 mesh pulp with an AAS finish, or if over 10 g/t Au, were re-assayed and completed with a gravimetric finish. The coarse crush split reject (<13mm) was retained for metallurgical testwork. 10% of a range of selected assays over 0.2 g/t Au, with an average of approximately 1.0 g/t Au were taken from the middling split reject and submitted for metallic screening analysis at 150 mesh pulp followed by fire assay and both AAS and gravimetric finish. Any discrepancies were reanalysed from the remaining middling reject by gravity concentration and acid digest. QC/QA included the insertion and continual monitoring of standards and blanks into 10% of the sample stream batches, along with check assays conducted at alternate accredited laboratories.
