    VANCOUVER, Aug. 6 /CNW/ - Quaterra Resources Inc. today announced that it
had extended the zone of primary copper mineralization in the Gallagher area
west of the MacArthur pit with drill results for two core holes and 15 reverse
circulation holes at its 100%-owned MacArthur project near Yerington, Nevada.
A further two RC holes located 1,500 feet north of the MacArthur pit
intersected strong secondary copper mineralization adding further definition
to a northern east-west section. A total of 18,893 feet of drilling are
reported in this release.
    At Gallagher, drilling encountered shallow copper oxide and chalcocite
mineralization overlying a zone of primary copper sulfide mineralization, with
chalcopyrite occurring both as veins and disseminations. Mineralization
extends discontinuously over a zone approximately 500 feet wide, 2,500 feet
long and 650 feet deep. Hole QM-44 penetrated oxide mineralization from the
surface to 60 feet averaging 0.22% copper. Below that level several intervals
of porphyry-style sulfide mineralization occur, including one intercept of
45 feet assaying 0.88% copper at 155 feet and 40 feet of 0.44% copper at
280 feet. The westernmost drill-hole (hole QM-46) intersected 76 feet of 0.74%
copper beginning at 1,279 feet (vertical depth of approximately 800 feet).
    Drilling indicates that primary sulfide mineralization does not extend to
depth directly beneath Gallagher. Mineralization drilled to-date most likely
represents the fringe of a porphyry system which may be present at depth to
the east or west of Gallagher. Detailed geologic mapping and an interpretation
of merged historic IP data will be completed before recommencing further deep
drilling.
    The MacArthur drilling program has also added to the definition of a
northern east-west section located 1,500 feet north of the pit. Chalcocite
mineralization in vertical hole QMC-02 was extended by angle holes drilled to
the east and west from the same collar location. Hole QM 34, drilled at an
angle of 45 degrees to the east, intercepted 210 feet of chalcocite
mineralization averaging 0.51 % copper at a depth of 240 feet. Hole QM-33,
oriented west at a 45 degree angle, intercepted 24 feet averaging 0.20 %
copper at a depth of 130 feet and a lower zone of 240 feet assaying 0.33%
copper at a down-hole depth of 175 feet. The intercepts form part of a
continuous zone of acid-soluble copper mineralization present over an
east-west strike distance of 4,000 feet. Drilling is now in progress on the
section 500 feet further to the north where the mineralization remains open
for extension. Core holes QM-26 and QM-36, reported in today's release, which
were drilled to test the deep porphyry copper potential north of the pit
intersected only narrow intervals of primary copper mineralization.
    Quaterra also announced the appointment of George Eliopulos as project
manager for MacArthur. Mr. Eliopulos has a Masters of Science degree in
geological engineering from the University of Arizona. His experience in
advancing projects from initial discovery through to feasibility for several
Nevada ore bodies will be invaluable to his work at MacArthur. His experience
includes positions with Rio Algom Exploration and Tenneco Minerals
Corporation. More recently Mr. Eliopulos has served as a consulting geologist
for private and junior mining groups with ownership interests in precious and
base metal properties in the western U.S.
    Quaterra plans to carry out detailed geologic mapping, IP interpretation
and additional drilling to define the zone of shallow acid-soluble copper and
search for deep porphyry copper mineralization. The drill data will be used to
complete a NI43-101-compliant resource estimate late this year.
    Mr. Eugene Spiering, Quaterra's Vice President, Exploration, is the
qualified person responsible for the preparation of this news release.

    Quaterra Resources Inc. (AMEX:   QMM, TSX-V: QTA) is a junior exploration
company focused on making significant mineral discoveries in North America.
The Company uses in-house expertise and its extensive network of consultants,
prospectors and industry contacts to identify, acquire and evaluate prospects
in mining-friendly jurisdictions with the potential to host large base metal,
precious metal or uranium deposits. The company's preference is to acquire a
100% interest in properties on reasonable terms and maintain this interest
through initial evaluation.
