Full Metal Commences Drilling at Grizzly Butte Copper-Gold Property, Alaska
05 August 2010 - 11:00PM
Marketwired
Full Metal Minerals Ltd. (TSX VENTURE: FMM) (the "Company") is
pleased to announce that the Company has commenced drilling at its
100% Grizzly-Butte copper-gold porphyry, located in south-central
Alaska. A Phase exploration program will include a 1,000 meter
drill program. To date no drilling has been completed at Grizzly
Butte.
The 5,131 hectare Grizzly Butte copper-gold porphyry prospect is
located in the Talkeetna Mountains, situated within 20 kilometers
of a paved highway.
Drilling will target a 'horseshoe' shaped copper anomaly
(greater than 280 ppm Cu) that measures 2,500 meters from east to
west and up to 700 meters in north-south dimension. A high of 4,020
ppm Cu occurs within the widest portion of the anomaly, and is
associated with an area of potassic alteration. In total, 350 soil
samples were collected during 2010, with 17% returning in excess of
280 ppm Cu. A total of 190 rock chip samples were collected on the
property, of which 26 assayed greater than 0.1% copper, with two
greater than 1.0% copper. Complete copper and gold soil results are
available on the company's website at
www.fullmetalminerals.com.
Full Metal recently completed an IP-resistivity survey and an
expanded soil grid over Grizzly Butte. The Property was last
explored by Kennecott Exploration in the 1990's. Historical
exploration of the area included programs by Cities Service and
Bear Creek Mining in the 1970's. Recently completed geologic
mapping has identified a potassic altered diorite intrusive unit,
with classic phyllic altered halo. Disseminated copper and gold
mineralization has been identified within the heart of the
alteration zone, as well as within sediment replacement bodies.
IP-resistivity surveys were completed over 14 line km spanning
four lines by Zonge Engineering. 200 meter Dipole-Dipole data was
used. A coincident IP high (greater than 60 mrad) and resistivity
high with a radius of 600 to 800 meters occurs within the heart of
the soil anomaly, and potassic altered intrusive units.
The Grizzly Butte prospect lies within a belt of rocks assigned
to the Triassic Amphitheatre Group of the Wrangellia terrane,
consisting of basalt flows and minor interflow argillite,
limestone, and tuff, commonly with gabbroic sills. These rocks are
intruded by a 1.2 square kilometer mapped area of various phases of
K-feldspar altered diorite. Aeromagnetic data suggested this
complex is much larger. A 1000 by 2000m NE-SW zone of strong
potassic alteration is centered about diorite-syenite, and
overprints the surrounding volcanic rocks. Copper mineralization
occurs as disseminations, fracture fillings, and
quartz-pyrite-chalcopyrite stockwork within
magnetite/biotite-flooded rocks. One or more zones of sericite
alteration are present within the potassic zone; higher grades of
Cu mineralization may be associated with this alteration.
The 2010 exploration program is supervised by David
Hedderly-Smith, Ph.D., PG, Consultant for Full Metal Minerals, and
Robert McLeod, P.Geo., Vice-President Exploration of Full Metal
Minerals. Both are Qualified Persons as defined by NI 43-101. Drill
cores will be cut in half using a diamond saw, with one half placed
in sealed bags, and delivered to ALS-Chemex facilities in
Fairbanks, Alaska. A sample quality control/quality assurance
program utilizing standards and blanks, as well as third-party
check labs will be implemented. Contents of this release were

Full Metal is a generative exploration company with multiple
precious and base metal projects in Alaska and the Yukon. Work
during 2010 includes drilling programs at the 100%-owned Fortymile
zinc-silver-lead Property, underground development with Harmony
Gold at the Lucky Shot Property, as well as additional surface work
and drilling programs at several of Full Metal's Properties funded
by Joint Venture Partners.
