Gold in Lower Plate Limestone at Miranda Gold's Big Blue Project
Vancouver, BC, Canada - June 21, 2012 - 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.

| 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.
