Big Bear Mining Corp Announces up to 63.1 Gram per Tonne Gold From Surface Sampling on Lewiston Project in Fremont County, Wyoming

DENVER, CO--(Marketwire - Apr 12, 2012) - Big Bear Mining Corp (OTCBB: BGBR), a U.S.-based company focused on the acquisition and development of gold and other precious metal projects, today announced positive results from surface sampling on the Lewiston Project in Fremont County, Wyoming. The Lewiston property is an Archean greenstone hosted lode gold district. A total of 62 samples were collected, 48 grab samples from prospect pits and mine dumps, and 14 measured panel samples across mineralized shear zones. Fifteen (15) samples ranged from 1.0 gpt (grams per tonne) Au to 23.1 gpt Au and one contained 63.1 gpt Au. Selected highlights include:

• Hematite altered meta-graywacke containing quartz stringers from historical workings at the Hidden Hand Mine returned 63.1 gpt Au. Additional grab samples from adjacent prospect pits returned 0.558 gpt, 1.43 gpt and 2.16 gpt Au.
  
  
• Surface grab samples from a shear zone on the Wolf prospect ranged as high as 13.45 gpt gold, with 11 additional samples that averaged 2.4 gpt gold.
  
  
• Sampling at the Burr mine over four feet produced 19.9 gpt gold with a separate 18-inch sample producing 23.1 gpt gold. Samples were taken across an exposed shear zone containing quartz stringers and pods and are believed to be representative of the true width of the shear zone.
  
  
• Four samples collected from three prospect pits (the "Copper Pits") contained from 0.38 gpt Au to 5.68 gpt Au and from 0.30 % Cu to 1.81 % Cu. Samples were taken over a wide spaced area (4,400 ft.) from prospect pits on quartz vein-bearing structures.
  

"These positive results underscore the tremendous potential of the Lewiston Project and support our plans to commence drilling later this year," said James Baughman, president and CEO of Big Bear Mining. "We plan to initially focus our drilling on the Wolf prospect, where a 25 foot wide shear zone has been identified and where we believe that we'll benefit from a solid, historical body of sampling data dating back to the 1970s."

Sampling was performed under the supervision of James Baughman, Wyoming Registered Geologist. Big Bear utilized best practices Quality Assurance/Quality Control procedures by inserting standards, blanks, and duplicating results. Samples were secured until delivery to ALS Chemex. Analysis for gold was by fire assay with AA finish (Au-AA24, 50 g) and 33 additional elements by ICP (ME-ICP61).

The Lewiston Mining District is host to undrilled, high-grade gold veins that occur over a six-mile shear zone that has 32 historical shafts and adits and more than 177 prospect pits. Big Bear Mining has an option to acquire 100% ownership in 175 unpatented claims and three patented claims as well as eight patented claims and 10 unpatented claims under lease.
