Maestro Identifies New Gold Targets at Green Springs Project, Nevada

VANCOUVER, BRITISH COLUMBIA (the "Company") today announced that
the Company has identified new gold target zones in the first
geophysical survey over the Green Springs project in north-central
Nevada.
Several new zones have been identified using new geophysical
survey data, identifying new potential gold-bearing zones not
previously identified. These include possible new prospective fault
zones and identification of possible altered areas of the potential
gold-host horizon.
In addition to the geophysical survey, detailed geologic mapping
and a soil sampling survey are now underway, both of which will be
used to further delineate drill targets.
"While areas of outcropping gold mineralization and existing
open pits exist on the project, the geophysical survey was designed
to target areas with thicker, potentially higher-grade gold thaat
have not been recognized by prior explorers," commented Hans
Rasmussen, Director. "With this new geophysical survey data we
believe that the potential is here for a much greater area of gold
mineralization than previously thought. The data suggests there is
an excellent host rock at moderate depths under much of the
property with numerous target zones."
The Green Springs project is located in the vicinity of numerous
current and past-producing Carlin-type gold deposits. These include
Bald Mountain (+2 million ounces gold), Alligator Ridge (+700,000
ounces gold), Easy Junior (+200,000 ounces gold), Mt. Hamilton
(+450,000 ounces gold) and the Pan Property where Midway Gold is
adding to a large gold resource (+500,000 ounces gold).
Geophysical Survey Details
The objective of the survey was to better define the vertical
gold feeder faults and alteration related to gold emplacement, and
to better define the thickness and alteration of the horizontal
target horizon, the Pilot Shale Formation. A total of 16.6
kilometres of controlled source audio frequency magneto-telluric
(CSAMT) data were collected over most of the project. CSAMT is a
resistivity mapping tool capable of high-resolution near surface
down to 1000 metre depths.
Mr. Rasmussen further commented, "With this new geophysical
survey data we have made significant leaps in understanding the
gold host and mineralization controls on the project. This data,
when integrated with other known data, has provided high-quality
drill targets for future drilling at Green Springs."
Small-scale gold production at Green Springs has been
historically mined from the base of the Chainman Shale, a unit of
thin bedded silty limestone 50 to 150 feet thick. The target unit,
the Pilot Shale, is a much thicker (over 200 feet thick) and
regionally more productive host unit, and occurs at depths of 0 to
500 feet over much of the property. The Pilot Shale was the host at
the Alligator Ridge Mine, 43 miles north of Green Springs. Within
the project area Maestro has collected rock chip outcrop samples
carrying from below detection up to 2.45 grams/tonne gold from
undrilled exposures of Pilot Shale.
The normal resistivity response of the Pilot Shale is variable
from moderate to low resistivities depending on carbon and pyrite
content. Portions of the Pilot Shale show significantly lower or
higher resistivities, either of which could represent alteration
related to gold mineralization.
Greater subsurface fault complexity was mapped with the CSAMT
showing more steep faults than had been previously identified. Some
of the steep faults show up as strong conductors, which may
indicate alteration within the faults themselves, thus implying
that they are gold feeders. This includes one fault that is known
to be a primary ore control in the largest historic production area
at Green Springs.
About Maestro Ventures
Maestro Ventures Ltd. is an exploration company focused on the
discovery of high-value precious and base metal deposits in the
eastern Great Basin. The Company currently controls mineral title
to nine projects in the Great Basin. While the company is focused
on expanding the gold resource at its Kings Canyon, Utah project,
the new Board of Directors and exploration staff are focused on
evaluating and adding high-quality projects to the portfolio.
Project generation is focused on two major metal-rich trends that
cross the eastern Great Basin.
