Bolero announces drill program at Cannivan Gulch Moly Project



    VANCOUVER, April 19 /CNW Telbec/ - United Bolero Development Corp. (the
"Company" or "United Bolero"), (TSX-V: UNB) announces it has engaged Ruen
Drilling, Inc. of Clark Fork, Idaho to conduct a 1,890 metre (approximately
6,200 feet) drill program on United Bolero's Cannivan Gulch molybdenum
deposit. The Company anticipates drilling on or about mid June subject to the
receipt of the required permit.
    The Cannivan Gulch property is located approximately 30 miles southwest
of Butte, Montana and was previously explored between the years 1968 and 1981
by Cyprus-Amax, Amoco Minerals and others. United Bolero has an option to
acquire a 100% interest in the property which consists of 15 original
unpatented claims covering 300 acres plus an additional 600 acres covered by
an additional 30 claims. Historic work by Cyprus Exploration Company included
a detailed exploration program with 55 core holes totaling 88,450 feet drilled
and 2,514 feet of underground development completed. Based on the results of
these earlier exploration programs, a non NI 43-101 compliant resource was
estimated by Amoco Minerals Company, in June 1982, at 300 million tons grading
0.06% Molybdenum ("Mo") containing 360,000,000 pounds of Mo. This historical
resource was calculated at a 0.03% Mo cut-off resulting in a preliminary pit
design with a 0.97:1 strip ratio. One objective of the work described below is
to bring this historical resource into NI 43-101 compliance. This historic
resource estimate quoted above, is considered to be relevant and is believed
to be reliable based on the amount and quality of historic work completed. The
Company has not completed the work necessary to independently verify the
classification of the mineral resource estimates. The Company is not treating
the mineral resource estimates as National Instrument 43-101 defined resources
verified by a qualified person. The historical estimates should not be relied
upon. The properties will require considerable further evaluation which the
Company's management and consultants intend to carry out in due course.

    
    Comments on Historical Results:
    -------------------------------

    - Higher grades within the deposit
       - Previous drilling indicates that the potential exists for a high
         grade core zone at depth
       - Historic Drill Hole CG-22 which was drilled in the central core zone
         in 1974 intersected 1,510 feet (from 250 feet to 1,760 feet) at
         0.12% Mo including 270 feet (from 580 feet to 850 feet) at
         0.21% Mo. (CMS laboratory as reported by Cyprus/Amoco Minerals.)
       - An adit and cross cut totaling more than 2,500 feet was driven by
         Cyprus/Amoco Minerals in 1980 to obtain bulk samples for
         metallurgical testing and to allow grab and channel sampling through
         the deposit

    Work Recently Completed:
    ------------------------

    - A review of all previous work on the property has been completed
    - A Plan of Operations for a drilling program was submitted to the U.S.
      Forest Service on March 12, 2007
    - Forty-six (46) drill pulp samples from the historical drill holes on
      the property were re-analyzed in 2007 by ALS Chemex. The new analyses
      track well with the historical Mo results and all results are available
      on the United Bolero web site.
    - New drill sections oriented north-south and east-west were constructed
      on 200 foot centers and new level plans were also constructed on
      200 foot centers. These were used to design the drill holes proposed
      for the 2007 drilling program that is presently under review by the
      responsible agencies. The sections and plans are also being used to
      evaluate mining methods and possible extensions of the mineralized
      system.

    Key Objectives of Cannivan Gulch 2007 Drill Program:
    ----------------------------------------------------

    - Four holes totaling approximately 6,200 feet (1,890 meters) have been
      proposed
    - The holes are designed to confirm and expand the historical Non-43-101
      Compliant resource
    - Core obtained in the proposed drilling will also be used for
      metallurgical studies to supplement the historic results
