Bear Creek announces positive step-out drill results; Growth continues at Corani silver-base metal deposits



    VANCOUVER, June 28 /CNW/ - Bear Creek Mining (TSX Venture: BCM) ("Bear
Creek" or the "Company") is pleased to announce results from an additional 29 
holes (5,725 meters) completed at the Corani silver-base metals project in
Peru. This brings the total drilling completed on this world-class deposit to
484 holes (81,678 meters). Highlights of this press release include:

    
    -   Drilling connects Minas Corani and Main Corani with high-grade
        interval returning 20 meters @ 315.8 g/t Ag, 3.2% Pb (C-223A);
        filling a gap in the resource model with high-grade.

    -   Minas Corani: 117 meters @ 71.8 g/t Ag, including 42 meters @
        129.1 g/t Ag (C-218).

    -   Main Corani, hanging wall: step-out hole returns 10 meters @
        106 g/t Ag and 1.0 g/t Au (C-211), opening up a new target area for
        additional gold mineralization with high-grade silver under the
        covered slopes west of Main Corani ore body.

    -   Mineralization remains open to the north and west of Minas Corani and
        Main Corani.
    

    Andrew Swarthout, President and CEO of Bear Creek, states "Even as we
move towards the pre-feasibility study stage, drilling continues to grow the
Corani silver-base metal deposits with many areas still open for further
additions. Increases in contained metals are expected in the upcoming fourth
resource estimate, scheduled to be completed by late summer. More importantly,
we expect a continued shift of silver and base metal resources from inferred
into measured and indicated categories. The expected timing of the updated
resource estimation will coincide well with completion of further
metallurgical testing. The completion of the next phase of metallurgical
testing will define the preliminary process flow sheet and confirm expected
recoveries, moving the project forward to advanced development and reserve
definition."

    Minas/Este - Step-out drilling continues to expand the mineralization and
infill drilling will allow conversion of inferred resources to measured and
indicated at robust grades. Drill hole C-223A intersected 20 meters @  315.8
g/t Ag, 3.2% Pb, filling in the un-drilled area connecting Minas Corani with
Main Corani. Additionally, infill drilling at Minas intersected 117 meters @
71.8 g/t Ag, including 42 meters @ 129.1 g/t Ag (C-218). Drill hole C221A (80
meters @ 36.8 g/t Ag) indicates that the Corani system continues to the north
under post-mineral tuff cover and that additional high-grade structures may be
intersected with continued step-out drilling. Results are pending for more
infill drilling that has been completed in Minas.

    Main Corani - Drilling in the hanging wall of Main at the southern end of
the main structure intersected 10 meters @ 106 g/t Ag and 1.0 g/t Au  (C-211)
indicating that high-grade structures can continue to be intersected in the
hanging wall and that, for the southern part of the structure, gold may become
an integral part of the mineralization.
    Drilling continues on Corani with one rig and the immediate plans include
drilling in the La Curva zone, located two kilometers south of Corani Este.
Drilling at La Curva will focus in an untested area stratigraphically higher
in the volcanic sequence where mineralization tends to be concentrated
elsewhere in the district. Additional drilling will then commence in the
southern Gold-Silver Zone located on strike, two kilometers south of Main
Corani.

    Metallurgical Testing - Metallurgical testing continues at SGS Lakefield
Laboratories with the objective of providing a preliminary process flow sheet
and projected recoveries in approximately two months time.

    Initial cleaner flotation test work has provided encouraging results and
our understanding of the behavior Corani mineralization has advanced greatly.
Selective cleaner flotation tests are in progress and early results indicate
that concentrate products will include separate lead/silver and zinc
concentrates, with remaining recovery being made up into a saleable bulk
concentrate. A component of silver dore production on site through leaching
part of the process stream is also envisioned.
    "As is common in the current environment of increased project loads and
limited lab facility capacity, the metallurgical testing turn-around remains
one of our greatest challenges," according to Mr. Swarthout. "Nonetheless, we
are very encouraged by the results to date; specifically, advances in
concentration ratios and in the production of saleable concentrates. Most
importantly, we remain confident that we will obtain ultimate process
recoveries of at least 80% for silver and 60% to 65% for both lead and zinc."
