Comaplex Reports an Updated Resource Estimate for the Tiriganiaq Deposit on the Meliadine West Property


    CALGARY, April 7 /CNW/ - Comaplex Minerals Corp. (TSX-CMF) is pleased to
report an updated resource estimate for the Tiriganiaq gold deposit on the
Meliadine West property. The property is located approximately 25 kilometers
northwest of Rankin Inlet, Nunavut, Canada. The Meliadine West property is
owned 78% by Comaplex Minerals Corp. and 22% by Meliadine Resources Ltd., with
Comaplex having an option to acquire an additional 2% from its partner for

    New Resource Estimate - Tiriganiaq Deposit (Meliadine West property)
    An updated mineral resource estimate has been completed on the Company's
Tiriganiaq gold deposit by Snowden Mining Industry Consultants Inc. (Snowden).
The updated resource, prepared in accordance with NI 43-101 requirements and
all previous resource estimates, incorporates all of the drilling in the
deposit, including that completed during the 2008 field season.
    The object of the 2008 drilling program on the Tiriganiaq deposit was to
move inferred mineral resources to a higher resource category, primarily in
the Western Deeps portion of the deposit. Recent assessment of the project
resulting from the underground exploration program and the Preliminary
Assessment, concluded that a shallower pit depth of 70 meters and a lower
cutoff grade of 5.5 g/t gold for the underground ore is justified for the
Tiriganiaq deposit (a 170 meter deep pit and a 6.5 g/t gold underground cutoff
were used for the previous two resource estimates). Measured resources are now
also included as a result of the underground bulk sample completed this past
year. Details on the 2009 resource estimate are outlined below:

    Tiriganiaq Deposit - Mineral Resources above 10,000m level (70m below
    cut-off grade
      (g/t Au)      category     tonnage    grade (g/t Au)    contained oz Au
    -------------   --------     -------    --------------    ---------------
         2.5        Measured     122,800        8.5               33,600
         2.5       Indicated   2,107,800        6.1              414,500
         2.5        Inferred     581,600        3.7               69,200

    Tiriganiaq Deposit - Mineral Resources below 10,000m level (below 70m
    from surface)
    cut-off grade
        (g/t)       category     tonnage     grade (g/t)      contained oz Au
    -------------   --------     -------     -----------      ---------------
         5.5        Measured     126,900       16.8               68,700
         5.5       Indicated   4,639,900       10.2            1,519,900
         5.5        Inferred   3,225,000        7.9              823,800

    2009 Total Indicated and Measures Resources = 2,036,750 oz gold
    2009 Total Inferred Resources = 893,000 oz gold

    To directly compare this year's resource estimate with last year's
estimate, Snowden re-ran the 2009 model using the old criteria of 2.5 g/t
cutoff for the pit, 6.5 g/t cutoff for the underground, and a 170 meter deep
pit. As shown below, the indicated and measured resource estimate for
Tiriganiaq increased by 430,000 ounces with the 2008 drilling.

    Measured &
     Indicated   7.64 M tonnes @ 7.3 gmt gold     1.79 M ounces       2008
                 9.01 M tonnes @ 7.7 gmt gold     2.22 M ounces       2009

    Inferred     4.88 M tonnes @ 8.8 gmt gold     1.39 M ounces gold  2008
                 3.61 M tonnes @ 6.7 gmt gold     0.78 M ounces gold  2009

    As expected in such an exercise, indicated and measured ounces increase
at the expense of inferred ounces. Indicated and measured ounces increased by
24% and inferred ounces decreased by 43%, resulting in an overall decrease of
ounces for the Tiriganiaq deposit of 5.5%. On this basis, Comaplex does not
view this as a material change in the resource estimate numbers for the
deposit nor does it view this as having any material effect on the results of
the February 2009 Preliminary Assessment of the property.
    As indicated in the press releases detailing the results of the 2008
drill program, intersections into the Western Deeps were robust and the
deposit is open to depth in all directions. Additional drilling in the deposit
in 2009 is expected to add overall resources and to continue the movement of
inferred resources to the indicated and measured resource categories.
    Block grades were estimated using a combination of Multiple Indicator
(1000, 1025, 1050 and 1100 lodes) and Ordinary Kriging estimation techniques
(all other lodes). Top-cuts, ranging between 7.6 - 105.0 g/t gold, were
applied where required. Additional details will be available in a resource
update report to be prepared by Snowden and released on the Comaplex website.

    2009 Meliadine West Exploration Program
    An aggressive exploration program has been approved for the Meliadine
West property in 2009. A total of 20,000 meters of surface diamond drilling is
planned commencing in early April and ending in September. The proposed drill
targets are intended to both increase and potentially upgrade the gold
resources in the Tiriganiaq and F Zone deposits, as well as test the potential
of the Wolf and Pump satellite deposits.
    Meterage will also be allocated to exploration drilling on the west end
of the property (~5 kilometers west along strike of the Tiriganiaq deposit).
The object of this drilling will be to locate the source of high grade
(multi-ounce) gold boulder fields in the immediate area. Further prospecting
of the property will also take place in 2009.
    Comaplex is presently completing a Preliminary Project Description for
the Meliadine property and will be forwarding this document to the regulatory
authorities to start the formal permitting process on the project. Discussions
with the various regulatory groups is ongoing and Comaplex is engaging several
northern experienced consulting groups to assist with the process.
    Significant time and expenditures will also be directed to ongoing
environmental, geochemical, and geotechnical studies required for a
feasibility study. Comaplex will proceed with the project in 2009 by engaging
the regulatory process, along with the commencement of a Feasibility Study.
    The underground exploration program at Meliadine West was completed in
the fall of 2008. Further underground exploration work will be planned. The
portal has been sealed, but if required, could be re-opened at any time for
further work.

    2008 Meliadine East Exploration Program
    Comaplex is presently reviewing the 2008 drilling data recently obtained
from its partner and operator (Meliadine Resources Ltd.) on the Meliadine East
property. This data, and a pending updated resource estimate for the Discovery
gold deposit, will determine what the 2009 exploration program will be.

    Mr. Dumka supervised drill hole planning, implementation and quality
control/quality assurance programs at the Meliadine West project for 2008.
Drill core analysis is performed on cut, half NQ core with standard fire assay
procedures and a gravimetric finish (2 assay ton, 1000 gram pulp). QA/QC
programs employ the insertion of external standards (low to high grade Au),
blanks, and core duplicates every 20 samples. All assaying was completed by
TSL Laboratories Ltd. based in Saskatoon, Saskatchewan. TSL completes its own
internal QA/QC by inserting a standard, blank, pulp duplicate, and coarse
reject duplicate in every batch of 20 analyses. QA/QC compliance was
rigorously checked on a continuous basis during the exploration program.
Meterage provided is measured down hole and intersection widths are
interpreted to be approximately 80% of true width, unless otherwise noted.
