Mantis Mineral Corp. reports high-grade extension of original Orphan Gold Mine



    TORONTO, Aug. 13 /CNW/ - Mantis Mineral Corp. ("Mantis" - CNQ "MINE") is
pleased to announce assay results of its diamond drilling program at its 100%
owned Orphan Mine site located 9-kilometers east of Kodiak's 'Golden Mile' in
the Beardmore-Geraldton area.
    1,312-meters of BWT (42mm diameter) coring in 8-drill holes were
completed and have confirmed the high grade nature of the Orphan Main vein.
The drilling has extended the Orphan Main vein to a depth of 65-meters below
the 75-meter level (250-foot level) and along a 225-meter strike length. This
doubles the original strike length and nearly doubles the vein target depth to
135-meters. Every hole drilled into the Orphan Main vein intersected the vein
with the exception of hole OMV08-7 which had to be stopped short as a result
of drilling difficulties. The results are summarized in the table below.
    In terms of significantly mineralized quartz, the best intersection has
come from hole OMV08-1 which intersected the Main vein at a vertical depth of
160-meters and was drilled along the shaft section. Hole OMV08-4 tested the
extension of the Main vein 43-meters to the southeast of the shaft at a
vertical depth of 100-meters. OMV08-2 was drilled between OMV08-1 and OMV08-4
and intersected the Main vein at a vertical depth of 107-meters. OMV08-3
encountered the vein at 107-meter vertical depth, 43-meters northwest of the
shaft. OMV08-5 intersected the Main vein at a 39-meter vertical depth,
103-meters northwest of the shaft. And OMV08-8 intersected the Main vein at
41-meter vertical depth, 131-meters northwest of the shaft.

    The Orphan Main vein was mined briefly in the 1930's and initially
produced 3,525-tons of ore grading 0.689 ounces per ton gold (23.62 gpt).
While these assays do not conform to National Instrument 43-101 they are
generally considered reliable according to local industry standards.
Historical records indicate that minimal mining was done in two very small
stopes leaving behind substantial ore. The Main vein's extent now encompasses
a target area along a 225-meter strike length from surface down to the
350-meter level.
    The results of this limited drill program are encouraging, and confirm
the high-grade nature of the Orphan Main vein below the 75-meter level of the
mine. There is no reason to doubt given the above results that the mine's
average grade of 0.689 ounces per ton (23.62 gpt) gold should not stand up at
greater depths. A second phase program is planned to test the vein at vertical
depths to 350-meters and along the 225-meter strike length hosting
330,750-tonnes of potentially gold bearing vein material. The Orphan Main vein
is a high-grade gold system not unlike the gold veins reported from Kodiak's
Hercules project.
    Commented Robin Ross, CEO, "The second phase drill program will be
designed to test the Main vein within the target parameters mentioned above.
The 330,750 tonnes has the potential to host a resource of 227,800 ounces of
gold. A third phase definition program contingent on the results of the second
phase will substantially add value to this property."
    Geologically, the former Orphan Gold Mine is situated in the
Onaman-Tashota greenstone belt of the Wabigooon sub province of the Archean
superior province. Traditionally this belt was referred to as the
Beardmore-Geraldton greenstone belt/gold camp.
    Gold production from this belt has exceeded 4.1-million ounces from
19-mines. The Orphan Gold Mine also known as the Dik Dik Mine is included as
one of the past producers of this belt. Mining operations were suspended due
to the economics of the time. The mine was developed on two levels, the
45-meter level and the 75-meter level which were accessed by an 80-meter deep
shaft. Lateral workings of crosscuts and drifts totaled 202-meters.
    Caracle Creek International Consulting Inc. is the Quality Assurance and
Control for the program.
    This news release has been viewed and approved by Walter Hanych, Senior
Geologist and Project Manager, who is a Qualified Person as defined by
National Instrument 43-101 and is responsible for program design and quality
control of exploration undertaken by the Company.
