    TORONTO, Oct. 30 /CNW/ - Columbia Metals Corp. Ltd. (TSX-V: COL), (the
"Company") is pleased to announce the acquisition of a Nordberg NW-1415 VFR
portable impact crushing plant from Excel Machinery Corp. of Amarillo, TX.
This equipment item is critical to the company's plan of pursuing commercial
production, in the near term, at the past producing Lluvia de Oro gold mine.
    The unit is a 1997 model, equipped with a Cat 3406 525 HP diesel engine,
a 48" x 20' vibrating grizzly feeder, a pan feeder, six (6) hydraulic legs
with auxiliary power, a four axle chassis and a 42" x 50' portable side
discharge conveyor.

    
    Associated equipment includes:

    a) New tow jeep, designed to move the unit.
    b) New skid-mounted Cummins 350 KW generator set.
    c) Lime system with hopper and rotary feeder.
    d) Two new 36" x 50' 20 HP field grasshopper conveyors.
    e) New Thor computer-operated, 36" x 150' powered radial stacker.
    f) Electrical system for operating the equipment.
    

    This crusher will be used to reduce the partially-leached ore on the
Lluvia de Oro heap to a nominal minus 1 inch size. The original metallurgical
test work, which was conducted prior to the commencement of leaching
operations in April 1996, indicated that at a nominal crush size of minus 1
inch, a recovery of 81% gold could be achieved.


    SART (Sulphidisation-Acidification-Recycling-Thickening) copper recovery
circuit

    As previously announced, Columbia Metals has signed an agreement with
BioteQ Environmental Technologies (TSX: BQE) for reagent treatment and
re-generation. Under the terms of the agreement BioteQ will finance, build,
own and operate a treatment plant that will recover dissolved copper from
solution and re-generate the reagent for use in the heap leach gold extraction
process. The plant is designed to use the SART
(Sulphidisation-Acidification-Recycling-Thickening) process developed by SGS
Lakefield Research and Teck Cominco, in combination with BioteQ's sulphide
technology.
    The civil contract for construction of the SART copper precipitation
circuit has been awarded to Akiwiki Construcciones, S.A. de C.V, a division of
Constructora Garaco, S.A. de C.V. of Hermosillo, Mexico. The scope of the
contract covers site excavation, electrical grounding, and reinforced slab

October 29 with an expected completion date in December of 2007. Installation
of tanks and mechanical components will follow the completion of worksite
preparation. Completion of the SART plant is scheduled for the first quarter
of 2008, just subsequent to first planned gold production at the site.
