Wednesday, December 15, 2010 – Bill Mavridis, President and CEO of Caldera Resources Inc. (“Company”), is pleased to announce that new videos from the Marjan Winter Drill program have been posted on the Company’s website. Please visit our website at http://www.calderaresources.com

Winter Drilling Program
The winter drill program commenced on November 10, 2010 and as of the 10^th of December, approximately 1500 meters have been drilled. The objective is to complete the first 2500 meters, of the anticipated 10,000-meter drill program, before Christmas. Drilling will continue in late January, in the New Year.Currently, two drill rigs are testing the eastern most boundary of the Marjan Central vein zone in order to determine the structural orientation of veins and associated alteration zones from approximately 2500m above sea level (“asl”) down dip to 2000m asl. Eleven drill holes totaling 1500m have been completed, with holes ranging from 120m to 288m.

The drilling is focused on Vein 1a, where the bulk of historic exploration work as well as recent Company sampling was concentrated; hole MC-11-2010 was drilled underneath trench 2, in which sampling of Vein 1a as well as hanging wall and footwall alteration zones returned a grade of 17.20 g/t Gold and 344.0 g/t Silver over 3.2 meters, including a 0.8 meter interval grading 51.3 g/t gold and 627 g/t of silver.

The core is being logged and samples are being prepared at a secure facility in Arevis, whereupon it is transferred by truck to the Company’s offices in Yerevan, and thence by airfreight to Activation Laboratories in Ancaster, Ontario. Results are expected in early January and will be released 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 260m 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.

The total C1 and C2 historical Soviet-era resources of the Marjan project are calculated at 405,147 oz of Gold and 14.2M oz of Silver. The total P1 historical Soviet-era resources of the Marjan project are equal to 647,152 oz of Gold and 37.1M oz of Silver.
