    MONTREAL, March 5 /CNW Telbec/ - Based on new sampling results from
levels 3 and 4 of the Huayllapon sector, Dynacor is pleased to announce that
it will intensify the exploration on this sector of the Pasto Bueno tungsten
property, in Peru. This sector is located approximately 2 km east of the
Huaura sector, already in production.
    A first series of sampling results, taken in November 2006 from a drift
on level 6, confirmed an average width of 1.54 m at 1.07% WO3 over 17 samples,
representing 44 of the accessible 102 metres of the Chabuca vein (see press
release dated November 15, 2006).
    In order to have a better understanding of the sector, Dynacor continued
sampling the accessible areas that had not yet been mined. One hundred and
thirty metres were sampled on level 3, of which 30 consecutive metres that
returned an average grade of 0.97% WO3 over a 0.85 metre width. Grading of
samples taken from the other 100 metres vary between 0.003% and 7.2% WO3. A
few samples were also taken on level 4 returned grades between 0.03% to    
1.21% WO3 on over 1 metre width. All the samples were assayed by an
independent laboratory (ALS-Chemex) using the W-XRF 10 method.


    Dynacor has already set-up an exploration and development program
estimated at US$2 million (including some mining equipment) to develop
reserves from this sector and start operations as soon as possible. "One
contractor was hired to start this new exploration phase on Huayllapon by
extending some existing adits and drifts and excavating new ones to uncover
new areas in that sector," said Jean Martineau, chairman of the board.
    The vein system is composed of twenty veins of which the most important
ones are Chabuca, Peligro and Santa Isabel. The Chabuca vein remains open,
projecting down dip and to the south. The Company estimates a 350,000 to
500,000 tonnes target potential grading 0.6% to 1.5% WO3 between levels 2 and
9 of this sector. At this time, the potential tonnage and grade are conceptual
in nature. Insufficient exploration has been done to define mineral resources
and further exploration will not necessarily result in the discovery of such
    Following the promising results from level 6, the Company decided to
continue exploration works on levels 4 and 6 and to develop levels 7 and 8.
Extensive exploration started in February 2007 by restoring 150 metres of adit
and will continue by excavating 650 additional metres to reach the mineralized
structure on level 8. In order to identify its potential a drift will be
excavated over 255 metres, and five raises of 100 metres each will be made to
connect levels 6 to 8. In addition, 200 metres of drifts will be excavated as
well to reveal the potential on level 7.
    Rehabilitation work and excavation of new drifts on level 4 and 6 will
also be carried out during the upcoming months. The construction of an access
road linking level 8 of the Huayllapon sector to the Huaura mill is now
completed which will allow a first bulk sample to be processed by the end of
the year.


    This sector was in operation on a regular basis from 1972 until 1982.
Based on information from previous plans of the mine and reports by the
geologist who covered the sector over the years, a minimum of 360,000 tonnes
was mined. More than 5,000 metres of drifts were excavated between levels 1
and 6, every 50 metres, on a total vertical distance of 300 metres.


    For the second quarter, the Company expects to reach the maximum capacity
of the Huaura mill at Pasto Bueno, or 250 t/d, while intensifying exploration
on the property. In February 2007, production reached 169 t/d.
