Bear Creek Drilling And New Sampling Expands Silver Mineralization On Its 100% Owned Santa Ana Project, Peru

Vancouver, B.C. - Bear Creek Mining (TSX Venture: BCM) ("Bear Creek" or the "Company") is pleased to announce results from thirteen additional diamond drill holes (Phase 3 drilling) and results from soil/rock chip grid sampling on the extreme north and south ends of the area drilled to date at its 100% owned Santa Ana silver project. Santa Ana is located 200 kilometers south of the Company's Corani silver-base metal deposit in southeastern Peru. Drilling at Santa Ana now totals 7,501 meters in fifty-five drill holes. Highlights of this press release include:

Drill hole SA-26A intersected mineralized volcanics with 128 meters @ 48 g/t Ag, including 14 meters @ 84 g/t Ag and 30 meters @ 91 g/t Ag.
Higher grade intervals intersected in SA-25 and SA-26; 4 meters @ 119 g/t Ag and 10 meters @ 95 g/t Ag, respectively.
Mineralization extended 350 m to the north and 400 m to the south through soil and rock-chip grid sampling, increasing the target size by 50%.
Mineralization remains open with strong vectors for extension in three directions plus at depth.

Andrew Swarthout, President and CEO of Bear Creek, states "The continuing positive results from Phase III underscore the potential for intersecting blind, higher-grade silver mineralization within the extensive volumes of lower grade silver halo at Santa Ana. The latest drilling and grid sampling significantly expands the footprint of mineralization and defines additional untested high grade zones that will likely contribute significant value to the discovery. Importantly, oxide mineralization continues to dominate; a factor that bodes well for the excellent leaching characteristics indicated by early metallurgical testing. We are expanding the Phase III drill program, as well as continuing our aggressive metallurgical test program. Mineralization remains open in all directions. A second drill has been requested in order to advance drilling towards the project's first resource estimation by year-end."

Mr. Swarthout continues "The drill is currently working to the north within the newly discovered soil/rock-chip grid anomaly approximately 150 meters north of the farthest north hole (SA-22) and a second platform an additional 150 meters north is next in line. Assay results from these holes will be reported as they become available in the coming weeks. Additional soils and rock geochemical sampling within the district is expected to further extend the target areas."

Drilling results are as follow. All intercepts are down-hole lengths and true widths have not been calculated.

Soil/rock-chip grid sampling -- Three larger areas of cover located to the north, south and southeast, and to the west of the area currently drilled have been grid sampled on 50 meters centers. To the north, an area measuring 250 x 300 meters contains rock-chip (subcrop) sample values of 24 to 95 g/t Ag. To the south and southeast, an area measuring 200 x 250 meters has rock sample values of 25 to 177 g/t Ag with supporting soil assays to 16 g/t Ag. Finally, to the west, single point values of 81 g/t Ag (rock) and 12 g/t Ag (soil) have been found. These anomalies define un-drilled target expansions on three sides of the deposit. Drill follow-up of the two large areas is underway and results will be reported as they are received.

Metallurgical Testing-- Metallurgical test work continues on schedule at McClelland labs (see news release dated 12 Apr, '07). This test work consists of several bottle role tests and finally three column leach tests designed to evaluate the heap leach potential of the project. Early parts of the test work confirm all the previous work that the Santa Ana material leaches very well. The column tests were started this week and are expected to run through the next few months. Final results of the test work will be reported upon completion of test work.
