Gold in Lower Plate Limestone at Miranda Gold's Big Blue Project

Gold in Lower Plate Limestone at Miranda Gold's Big Blue Project07:30 EDT Thursday, June 21, 2012 VANCOUVER, British Columbia (Business Wire) -- Miranda Gold Corp. ("Miranda") (TSX-V: MAD) is pleased to announce that Ramelius Resources Ltd. ("Ramelius") (ASX: RMS), our funding partner at Big Blue, a sediment-hosted gold project in Lander County, Nevada, has completed its Phase III drilling. Ramelius drilled a total of 2,860 ft (871.7 m) in two reverse-circulation holes. Both holes intersected anomalous gold mineralization in the carbonate section of the lower plate of the Roberts Mountains Thrust (“RMT”). This third round of drilling by Ramelius provided additional tests of structural and geochemical trends along Anomaly Ridge within the West Cottonwood Prospect and demonstrates potential for the carbonate stratigraphy in the lower plate of the RMT to host significant gold mineralization. Rock units on the surface of Anomaly Ridge are primarily siliceous siltstones, argillites, and cherts of the upper plate of the RMT and generate gold values in soil samples up to 0.025 oz Au/ton (0.850 g Au/t), in rock samples up to 1.70 oz Au/ton (58.2 g Au/t), and in drill samples up to 0.178 oz Au/ton (6.110 g Au/t). Additionally, Phase II drill hole BBR11-05 intersected highly anomalous pathfinder elements in the lower plate of the RMT with values up to 1,360 ppm arsenic, 116 ppm antimony, and 5.4 ppm mercury. These elements generally form abundance highs near gold mineralization. All holes drilled to date at Big Blue have intersected detectable gold mineralization. The following table summarizes significant drilled gold intersections (defined as those gold grades of 0.01 oz Au/ton (0.343 g Au/t) or higher over intersections of 5 ft (1.5 m) or longer) for the 2011 and 2012 drilling. The anomalous and significant intercepts in Phase I and II drilling are in the upper-plate of the RMT. Better host rocks for sediment-hosted gold mineralization are considered to be the limestone formations beneath the RMT and the Phase III significant gold intersections below 1,000 ft (305 m) are in these limestones.     Hole ID   TotalDepth(ft)   Interval(ft)   Length(ft)   Grade(oz Au/ton)   Interval(m)   Length(m)   Grade(g Au/t)PHASE I               BBR11-01 1,120 10-40 30 0.048 3.0-12.2 9.1 1.631 Includes15-2050.1784.6- 70-80 10 0.019 21.3-24.4 3.0 0.651 BBR11-02 475 70-75 5 0.015 21.3-22.9 1.5 0.515 90-95 5 0.018 27.4-29.0 1.5 0.624 BBR11-03 275 55-80 25 0.043 16.8-24.4 7.6 1.491 90-95 5 0.033 27.4-29.0 1.5 1.135 BBR11-04 575 45-65 20 0.018 13.7-19.8 6.1 0.617 195-200 5 0.017 59.4-61.0 1.5 0.573 PHASE II BBR11-05 835 125-130 5 0.011 38.1-39.6 1.5 0.375 185-190 5 0.012 56.4-57.9 1.5 0.406 PHASE III BBR12-01 1,480 25-30 5 0.014 7.6-9.1 1.5 0.492 1,155-1,165 10 0.015 352.0-355.1 3.1 0.517 BBR12-02 1,380 220-225 5 0.035 67.1-68.6 1.5 1.19 1,005-1,010 5 0.011 306.3-307.8 1.5 0.375 1,040-1,045 5 0.048 317.0-318.5 1.5 1.660         1,080-1,085   5   0.011   329.2-330.7   1.5   0.386 Maximum gold intercepts in BBR11-06 and -07 are 5 ft (1.5 m) of 0.104 and 0.128 g Au/t, respectively. Original data are in feet and Au ppm (g Au/t). True thicknesses of gold intercepts cannot be determined.   Quality Assurance / Quality Control procedures utilized by Ramelius during the analyses of drill samples include collection of duplicate samples and insertion of blanks and analytical standards into the sample sequence. Control samples constitute about 10 percent of each batch of samples. All drill samples were analyzed by ALS Minerals with gold analyses by fire assay of a 30 g charge and AAS finish and trace-element analyses by ICP-MS. The drill contractor for Phase III drilling was Boart-Longyear. Data disclosed in this press release, including sampling, analytical and test data, have been reviewed and verified by Vice President of Exploration Joseph Hebert, C.P.G., B.Sc. Geology and Qualified Person as defined by National Instrument 43-101. Project Details The Big Blue Project consists of 255 unpatented lode mining claims covering 8.2 sq mi (21.2 sq km) located in the Toiyabe Range, 13 mi (21 km) north of Austin, Nevada. The project is on the south margin of the Callaghan Window, a large area exposing Cambrian- through Silurian-age lower-plate carbonate rocks in the footwall of the Roberts Mountains Thrust. The lower-plate sequence includes the Roberts Mountains and Hanson Creek Formations and the Pogonip Group, of which all are known to be favorable hosts for large, sediment-hosted gold systems in Nevada. Corporate Profile Miranda Gold Corp. is a gold exploration company active in Nevada, Alaska, and Colombia and whose emphasis is on generating gold exploration projects with world-class discovery potential. Miranda performs its own grass roots exploration and then employs a joint venture business model on its projects in order to maximize exposure to discovery while minimizing exploration risk. Miranda has ongoing partnerships with Agnico-Eagle (USA) Inc., Montezuma Mines Inc., Navaho Gold Ltd., NuLegacy Corporation, Ramelius Resources Ltd., and Red Eagle Mining Corporation.
