TORONTO, March 7, 2011 (GLOBE NEWSWIRE) -- PDAC 2011 Convention: Caldera Resources Inc. (the "Company") (TSX-V:CDR) is pleased to announce the receipt of overlimit silver, lead, and zinc assays from drill hole MC-08-10. Samples carrying in excess of 100 g/t silver, 0.5% lead, and 1.0% zinc, as reported in News Release January 12, 2011 were reassayed to determine actual intersection values. Samples were digested in 8-acid aqua regia followed by assay by induced neutron activation analysis (INAA).

Overlimit assay results, combined with previously reported values not requiring reassay, total 2.59 g/t gold, 164 g/t silver, 0.13% copper, 4.34% lead, and 4.34% zinc. This interval spans 7.1m, from 139.5m to 146.6m, and covers the central silicified vein zone plus additional continuous mineralization in the silicified, pyritized, and argillically altered hanging wall and footwall alteration zones. The intersection is anchored by the first 1.10m section of the vein zone, with values of 5.39 g/t gold, 431 g/t silver, 0.26% copper, 12.4% lead and 15.3% zinc, from 141.5m to 142.6m downhole.

* Items with an asterisk were overlimit and reassayed. See NR of Jan. 12, 2011 for a complete list of results.

The hanging wall of the MC-08-10 vein zone spans 2.0m and carries values of 1.16 g/t gold, 40.60 g/t silver, 0.04% copper, 2.43% lead, and 2.49% zinc. The vein itself spans 3.1m and carries 4.58 g/t gold, 276 g/t silver, 0.23% copper, 7.38% lead and 7.59% zinc. The footwall of the MC-08-10 vein zone spans 2.0m and carries 0.95 g/t gold, 114 g/t silver, 0.07% copper, 1.56% lead, and 1.15% zinc.

The mineralized zone remains open on the footwall, with the lowermost reported sample returning 0.62 g/t gold, 197.0 g/t silver, 0.12% copper, 0.61% lead, and 0.82% zinc. Further footwall samples have been prioritized for assay.

Jim Steel, MBA, P.Geo, Vice-President, Mining and Development for Caldera, stated: "This appears to be a recurrent theme at the Marjan Gold-Silver Project. Mineralization is not found solely in highly silicified and mineralized, vein material, but also in strongly altered hanging wall and footwall samples. Results to date confirm our belief that the underlying Soviet-ear data is of excellent quality and is reproducible."

Drill hole MC-08-10 was located at 573453E and 4359739N (zone 38S; WGS84 datum), drilled on an azimuth of 240 degrees at a dip of -78 degrees. The hole was targeted to hit vein 1a between Adit 2 at 2424m and a road exposure of vein 1a at 2480m.

The exploration program is designed to confirm historical Soviet-era data. These historical estimates are presented for historical reporting and to provide a basis for assessing Caldera's choices for its business activities. A qualified person has not done sufficient work to classify the historical estimate as current mineral resources and the historical estimate should not be relied upon or understood to indicate the existence of reserves or resources.

All samples from all holes have been received at Activation Laboratories Ltd in Ancaster, Ontario. Additional results will be announced as soon as they are available.

The Marjan Gold-Silver Project

The Marjan Gold-Silver Project is a high-grade gold and silver epithermal vein system, with three distinct zones. The Marjan Central Zone consists of multiple anastomosing silicified veins in a zone of propylitic and argillic alteration some 500m wide east-west and over some 1000m vertically. The Marjan North Zone consists of parallel sulphide veins and alteration zones that outcrop over a 400m by 400m area as well as a potentially mineralized clastic unit some 1.6km long by some 600m wide.

Historical Soviet-era Resources at the Marjan Gold-Silver Project

The Marjan Central zone was extensively explored between 1964 and 1989, and has Soviet-era GKZ standard resources as outlined below:

Historical Resources          
Marjan Central

P1 resources  3,211,843 2.35 g/t 93.42 g/t  242,696 9,647,922

The Marjan Northern zone was explored between 1991 and 1992 by the Sissian Geological Exploration Group, and published by the State Committee for Reserves of Armenia, Yerevan, has historical Soviet-era GKZ standard resource, as follows:

Historical Resources          
Marjan Northern          
Zone only   tonnes   Gold   Silver   Gold oz   Silver oz
P1 resources   5.77M   2.18 g/t   148.46 g/t   404,456   27,543,865

The total C1 and C2 historical resources of the Marjan project outlined above are equal to 405,147 oz of Gold and 14.2M oz of Silver. The total P1 historical resources of the Marjan project are equal to 647,152 oz of Gold and 37.1M oz of Silver.
