VANCOUVER, Dec. 13, 2012 /CNW/ - SIERRA IRON ORE CORP (the "Company") is pleased to announce that it is has successfully staked additional mineral claims adjacent to the Tom Cat property in British Columbia, Canada. With the addition of the newly staked claims, the Tom Cat property is now comprised of ten contiguous mineral claims covering an area of 4013 hectares.

The Tom Cat property is located 200 kilometers east-northeast of Vancouver within the historic Aspen Grove copper camp and shares a property boundary with the Big Kidd property that was recently optioned by Extrata and currently under exploration. The region is well known to host some of the world's largest copper resources including those at Copper Mountain and at the Highland Valley.

The Tom Cat mineral prospect, one of nine MINFILE reported mineral zones on ground covered by the claims of the Tom Cat property, has been explored by prospecting and trenching since 1906. The predominant mineralization is hosted in green laharic breccia or basaltic flow breccia near the contact with red laharic breccia of the Upper Triassic Nicola group.

Garrow (2010) reports that the only significant results reported prior to 2006 was a drill intersection of 45.7 meters of 0.32% copper in a 1965 Pyramid Mining drill hole on the Tom Cat showing. Included in the historic drill hole was an intersection of 4.4 meters of 0.54% copper.  Exploration work by Bold Ventures in 2006 & 2007 on the Tom Cat property resulted in the delineation of variable chargeability IP drill targets that may indicate a mineralized sub-surface porphyry system. Sierra has obtained a permit for drilling and will be proceeding with a diamond drilling program to test some of the IP anomalies.

Please note that historic information cannot be relied upon until the information is confirmed through a work program by the company.
