- SR-184 - 28.80m at 1.54 g/t Au from 178.00m down hole
- SR-186 - 63.40m at 1.36 g/t Au from 107.80m down hole (incl. 1.00m at 37.00 g/t Au)
- SR-189 - 8.70m at 7.11 g/t Au from 154.80m down hole (incl. 1.00m at 36.10 g/t Au)
- SR-202 - 2.30m at 35.72 g/t Au from 129.40m down hole (incl. 0.70m at 77.60 g/t Au)
- SR-211 - 23.30m at 3.50 g/t Au from 91.10m down hole (incl. 4.45m at 15.25 g/t Au)
- SR-215 - 24.00m at 9.03 g/t Au from 112.50m down hole (incl. 3.10m at 39.30 g/t Au)
- SR-219 - 6.00m at 9.83 g/t Au from 156.00m down hole (incl. 1.40m at 36.00 g/t Au)
"Our Phase Four drilling programme has successfully delineated the resource to 250 metres depth and extended the resource to more than 500m at depth", comments Jeff Toohey, Vice President Exploration. "Over 90% of drill holes encountered economic mineralisation including high grades over significant intervals."
An updated Resource Estimate planned for release in July, 2013 will incorporate all of the Phase Four results including infill drilling to 50m centres to a depth of 250m which is expected to upgrade a majority of the existing Inferred Resources below 100m to the Measured and Indicated classifications. In addition, the San Ramon Gold Deposit remains open at depth and has the potential to be mined from underground (at a 2 g/t Au cut-off the current Inferred Resource averages 5.44 g/t Au). Therefore, the July 2013 Resource Estimate will also incorporate broad spaced drilling completed to date, from approximately 250m to 500m depth to establish an Inferred Resource suitable for potential development by underground mining methods. The July Resource Estimate will be incorporated into a Preliminary Economic Assessment and Environmental Impact Assessment planned for release early in the autumn of 2013.
The San Ramon deposit trends east-west, dips 70° to the north, extends over 1,900m, is up to 50m wide and is mineralised from surface. A total of 45,000m of core in 233 holes have been drilled to a vertical depth of more than 500m with mineralisation remaining open at depth. The initial, January 2013, Resource Estimate based on 23,000m of drilling to a depth of 300m included an Indicated Resource of 7.34 million tonnes at 1.37 g/t Au containing 322,000 ounces gold and an Inferred Resource of 9.45 million tonnes at 1.50 g/t Au containing 456,000 ounces gold. All of these Resources occur at the San Ramon Deposit, one of numerous gold prospects undergoing exploration at Santa Rosa. Metallurgical test work to date has returned an average CIL gold recovery of 94%.
For complete drill results, please see Table 1 - Drill Hole Intercepts, Table 2 - Drill Hole Specifications and Figure 2- Long Section (showing drill hole pierce points). Drill holes up to SR-225 have been previously released. 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. Drill assays were composited by length-weighted averaging into intersections using a 0.30 g/t Au cut-off grade. Due to the mining method and mining selectivity contemplated for the deposit, internal dilution was included in some intersections where considered appropriate for mining continuity.

Quality Assurance and Quality Control
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 (<16mm) 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. QA/QC 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.

Red Eagle Mining is developing the 390 km² Santa Rosa Gold Project located in Antioquia, Colombia. Santa Rosa is an intrusive hosted structurally-controlled quartz stockwork system within the prolific Antioquia Batholith. Gold mining within the Santa Rosa Gold Project pre-dates the 16th century when an estimated 30 million tonnes were mined. Santa Rosa is located 70km north of Medellin near the town of Santa Rosa de Osos in a region characterized by gently rolling hills and excellent infrastructure. Santa Rosa is also located approximately 30km west of AngloGold Ashanti's Gramalote gold deposit (2.5 million ounce M&I resource grading 0.8 g/t Au) and 40km east of Continental Gold's Buritica gold deposit (1.6 million ounce M&I resource grading 13.6 g/t Au). Red Eagle Mining holds an extensive package of exploration ground throughout Colombia, including the Pavo Real Gold Project.
