Pershimco and Dia Bras Outline New Higher Grade Silver Zone at the San Miguel Mine, Cusi Mining District, Mexico

10:45 EDT Thursday, July 10, 2008

CHIHUAHUA, MEXICO--(Marketwire - July 10, 2008) - PERSHIMCO RESOURCES INC. (TSX VENTURE:PRO) (FRANKFURT:BIZ) ("Pershimco") and DIA BRAS EXPLORATION INC. (TSX VENTURE:DIB) ("Dia Bras") (the Joint Venture or "JV") are pleased to announce the discovery of a new silver zone outlined by underground chip sampling at the historical San Miguel Mine, located on the San Miguel and La Bamba Properties (the "Properties") in the Cusi Mining District, State of Chihuahua, Mexico.

The new zone, termed El Convento Chimney, is a higher grade silver, zinc and lead target with significant gold. This new zone adds, with the known La Bamba and San Miguel zones, a third chimney in the silver mineralized system.

Dia Bras previously chip sampled the 410 m long 5th Level in 2007, located approximately 150 m below surface along the San Miguel / La Bamba mineralized corridor. A total of 91 chip-channel samples were taken from the "back" or top of the 5th Level drift across the silver-sulphide mineralization at approximately 5 m intervals along the entire 410 m drift and the 25 m long cross-cut (chip-channel assay results for silver are given in the appended Table 1). The 410 m drift averaged 103 g/t silver; whereas the crosscut averaged 168 g/t silver over a 25 m length.

The JV, operated by Pershimco, undertook structural mapping and selective channel sampling program on the 5th Level to verify and validate the recent and historical underground work (assay results from channel samples are given in the appended Table 2). Results of this sampling are as follows:

- the hanging wall section of the 75 degrees plunging El Convento Chimney averaged 0.27 g/t gold, 209 g/t silver, 0.55% zinc, 0.06% copper and 0.65% lead over 1.70 m (samples N5-23 and 24);

- the El Convento Chimney graded 0.62 g/t gold, 297 g/t silver, 6.53% zinc, 0.42% copper and 8.62% lead over 1.50 m (sample N5-25); and

- the footwall of the El Convento Chimney averaged 0.96 g/t gold, 311 g/t silver, 3.64% zinc, 0.16% copper and 3.77% lead over 1.50 m (samples N5-26 and 27).

Samples from the El Convento Chimney represent an area of approximately 535 m2. The potential to extend to a vertical depth of -500 m based on the known silver mineralization in the Cusi Mining Camp appears promising, thus potentially increasing significantly the known mineralized structure. Further work will be required to define a National Instrument (NI) 43-101 compliant mineral resource. There is no certainty that any future work would demonstrate viable Mineral Resources.

Pershimco's President and CEO, Mr. Alain Bureau, P. Eng., states "The latest underground work by the JV is showing the potential for higher grade silver-rich chimneys in three areas of the Properties extending from the La Bamba open pit, within the San Miguel underground workings, to the north of La Bamba, and now a new area termed El Convento Chimney further to the north, covering a distance of more than 600 m. We are also quite surprised with the significant content of gold and base metals as we go deeper."

Dia Bras President and CEO, Mr. Daniel Tellechea, states "The work undertaken under the auspices of the new JV partnership with Pershimco demonstrates the favourable potential of the La Bamba-San Miguel area and could add significant resources in the future to the resource base of the Cusi project of Dia Bras."

This news release has been prepared and reviewed by Mr. Jean Lafleur, P. Geo., Director and Technical Advisor at Pershimco, the Company's Qualified Person under National Instrument (NI) 43-101 regulations.

(i) Sample preparation was done at the Laboratorios Mineros del Norte SA de
    CV, in Chihuahua, Mexico, a division of Techni-Lab SGB Abitibi Inc.
    Samples were bagged, tagged and sealed in the field. Samples were then
    transported to Chihuahua for drying, crushing and pulverizing. A more
    or less 500 g fraction of the crushed sample was split using a riffle
    splitter, producing a -10 mesh crushed samples which were sorted and a
    200 to 300 g portion was taken for pulverization to 80% at -200 mesh to
    be packed, tagged, and shipped to the Techni-Lab SGB Abitibi Inc., in
    Ste-Germaine-Boule (Quebec, Canada) for assaying. Samples were then
    analyzed using the Fire-Assay method for gold, silver, copper, zinc and
    lead. Laboratory standards, blanks and duplicates were added to the
    sample batches.
