VANCOUVER, BRITISH
COLUMBIA--(Marketwire - Nov. 17, 2009) - GEO MINERALS LTD. (TSX VENTURE:GM) (The "Company" or "Geo") is pleased to announce it has entered into two
separate option agreements with Inmet
Mining Corp. (TSX:IMN) to explore the Company's porphyry copper projects
located in the Arizona porphyry copper province. Inmet will have the option to
earn a 70-percent interest in the Company's Red Hills property and a 70-percent
interest in the Company's Middle Mountain property by making cumulative cash
payments of $675,000 and exploration expenditures of $2,000,000 over five years
on each of the Projects. Both option agreements are subject to conditions
precedent, including the receipt of any necessary third party approvals.
The Projects represent exploration
targets that lie within a broad belt of porphyry-copper mineralization that
stretches from Globe-Miami (in production by Freeport-McMoRan Copper &
Gold, BHP-Billiton, and Quadra Mining) westward through the deposits at
Resolution (in development by Rio Tinto–BHP), Ray (in production by ASARCO),
and Florence-Poston Butte (undeveloped). The Company holds its interest in the
Projects under option from Bronco
Creek Exploration Inc. ("BCE"), a target-generation team based in Tucson,
Arizona. BCE geologists originally identified the targets at Middle Mountain
and Red Hills through surface mapping of porphyry-style alteration and
mineralization; analysis of existing geologic maps, geochemical and geophysical
data; and reconstructions of regional and district structural geology.
The Middle
Mountain property covers approximately 7,070 acres and is located in the westernmost foothills of the Tortilla Mountains approximately 16 kilometres southeast of
Florence, Arizona. On Jan. 8, 2009,
the Company announced results of the first-phase drill program at Middle
Mountain, which consisted of two reverse-circulation drill holes (1,000 and
1,200 feet (300 to 360 metres), respectively) and six shallow holes (ranging
from 168 to 600 feet (51 to 182 metres)). Intense sericite-pyrite alteration
typical of the outer pyritic shell related to a porphyry copper-molybdenum
deposit was intercepted in eastern portions of the project area in hole MM-13
at a depth of 680 feet (207 metres), in MM-19 at 498 feet (151 metres) and in MM-20
at 80 feet (24 metres). Sodic-calcic alteration, which typically defines the
deep flanks of a porphyry system center, was identified in MM-17 and MM-18 in
the northwest portion of the property position and is consistent with BCE's
structural model of the hydrothermal system as dismembered and rotated
approximately 90 degrees. Based upon these results, a follow-up drill program
has been designed to target prospective zones just southwest of the first-phase
drilling.
The Red Hills project is
located five miles north of the Middle Mountain project, also in the
westernmost foothills of the Tortilla Mountains, and covers approximately 7,461
acres. Outcrops in the Red Hills area display a portion of a large rotated and
dismembered porphyry copper system. Within these limonite-stained outcrops, a
large low-grade historic resource has been defined that borders the Company's
property position. The hills are composed of Precambrian granitic and diabasic
rocks, and represent tilted fault-bound structural blocks marked by outcrops of
steeply east-dipping post-mineral sedimentary rocks. The host-rocks are
cross-cut by a number of pebble dikes containing copper-mineralized clasts and
swarms of porphyry dikes. The outcropping porphyry dikes are spatially
associated with zones of sericitic alteration containing quartz-sulfide veins
that locally contain copper oxides. In the westernmost outcrops, in addition to
sericitic alteration, zones of biotitic alteration are observed. BCE geologists
interpret the observed alteration and mineralization to represent the uppermost
levels of a porphyry copper system. The eastward-tilted structural blocks, the
westward zoning of sericitic to biotitic alteration, and the presence of
mineralized clasts in the pebble dikes all suggest that the deeper, more
productive portions of the system lie to the west beneath cover rocks within
the Company's property position. On
Jan. 8, 2009, the Company announced results of the first-phase drill program at
the Red Hills project, including an interception of exotic copper oxide
mineralization. Continued exploration under this agreement with Inmet will
further target buried deeper levels of the exposed porphyry copper system.
"We are very
pleased to have made this arrangement with Inmet. This agreement allows Geo to
create shareholder value without diluting its capital structure. While we have
the early stage exploration expertise, Inmet will have the financial and
technical horsepower to bring a huge copper porphyry to production, should a
discovery be made," stated Company president and chief executive officer
Mike England.
