Prime Meridian Resources Corp.: Copper Mineralization Intersected at Wilson Creek IOCG Project
January 09 2008 - 8:00AM
Marketwired Canada
Prime Meridian Resources Corp (TSX VENTURE:PMR) (FRANKFURT:DYD) ("Prime
Meridian") is pleased to provide an update on its activities.
- Drilling has intersected copper mineralization at the Wilson Creek Iron
Oxide-Copper-Gold ("IOCG") project;
- drilling will commence in mid January on the TAG and JAKE magmatic
nickel-copper targets in the Upper Peninsula of Michigan;
- drilling will commence in February on the Winterfire nickel-copper project in
Minnesota.
Prime Meridian initiated the drilling of its portfolio of properties in the
Spring of 2007 and plans to continue this drill program during 2008, the current
focus being areas which are best accessed during the winter drilling season. The
Company is continuing its business model of systematically drill testing a
series of projects it has acquired and advanced since 2000, each project having
the potential to provide a significant mineral discovery.
Wilson Creek IOCG Project, Michigan
Prime Meridian has completed 4 drill holes on separate targets in the Wilson
Creek Project Area, 3 of them being within the Main Grid Area ("MGA"). The MGA
covers an area of approximately two miles by three miles. Assay results have
been received for 3 of these holes. Copper mineralization, alteration, mineral
assemblages and structural features characteristic of IOCG deposits were
intersected in all three drill holes within the MGA.
The most encouraging assay results were received from the second drillhole
within the MGA, DDH WC-2, which tested a coincident magnetic and electromagnetic
response in close proximity to anomalous surface samples.
Interval (ft) Thickness (ft) Cu (%)
------------- -------------- ------
586-592 6 1.25
888-896 8 0.98
This hole was drilled at a 45 degree angle and intercepted bedding and structure
at nearly 90 degrees, thus giving approximate true thicknesses. Contained within
the intervals above are thin, 2" to 8" thickness of veined, massive chalcopyrite
with trace amounts of gold, tungsten, and bismuth and abundant magnetite,
hematite fluorite, epidote, K-spar, tourmaline, albite and chlorite alteration,
all of which are typically associated with IOCG deposits. Additionally, copper
mineralization occurs disseminated at various intervals throughout the hole. The
best value is from 603 to 611 feet, 8 feet of 0.045% or 447 ppm copper.
Anomalous geochemical values were also received for numerous Light Rare Earth
Elements.
The vein-related mineralization present in this hole has been developed within
structural zones that have served as conduits to allow the mineralizing fluids
to ascend from a source at depth, laterally, or both. These structures are
critical to the development of large-tonnage copper deposits when hydrothermal
fluids are introduced into favorable environments, which Prime Meridian's
previous work has identified to be present at Wilson Creek.
WC-1, testing a magnetic anomaly beneath very large, angular, subcropping
mineralized boulders, had several intervals with geochemically anomalous results
for copper, gold, tungsten and bismuth, all of which are associated with
strongly altered rocks. The best copper values are from 627 to 635 feet, 8 feet
of 0.05% or 495ppm copper.
WC-3 was collared to test an electromagnetic anomaly discovered from the
airborne surveys and confirmed with ground follow-up geophysical surveys. This
hole was not completed to the targeted depth because of the hunting season but
will be deepened when the drill testing of the remaining targets at Wilson Creek
resumes later in 2008. To date, trace amounts of copper mineralization have been
observed in the core from WC-3, however, the targeted geophysical anomaly had
not been reached when drilling was halted in November for the hunting season and
for drill maintenance.
The other hole, DDH S9-1, located outside of the MGA, did not intercept any
significant results.
Within the MGA it is very important to note that Prime Meridian's geological
reconnaissance samples from outcrop and subcrop contained anomalous
copper-gold-tungsten-flourine mineralization and associated hydrothermal
alteration, as seen in the drilling. Values from very large, angular subcropping
boulders were 2.69% copper, 0.01 oz/ton gold, 0.41 oz/ton silver, 0.13%
tungsten, 0.3% fluorine and 0.02% molybdenum. These analyses are from rock
samples of hydrothermal veins in mafic volcanics, the same style of
mineralization intersected in DDH WC-2. Additionally, values of 1.03% copper
were assayed from rock samples exhibiting a disseminated style of mineralization
within the host mafic volcanics, a rock type which represents a favourable
environment to form a large tonnage deposit.
In addition to the drilling, ground-based induced polarization, magnetic and
electromagnetic surveys were completed in November, 2007. These surveys
developed a minimum of four new high priority exploration targets that will be
drill tested within the MGA area. These are new geophysical targets relating to
the possible existence of a large tonnage copper occurrence and are independent
of the nine targets previously defined within the MGA on the basis of Prime
Meridian's previous work.
Prime Meridian is encouraged that the IOCG model has been further confirmed as a
strong and large system hosting copper mineralization. The drilling and
geophysical results combined with Prime Meridian's earlier work have advanced
the understanding of the Wilson Creek IOCG project.
Prime Meridian will use the winter drill season to test other projects requiring
winter access. The Company plans to continue drilling at Wilson Creek after the
spring break up period.
TAG Nickel-Copper Drilling, Michigan
Prime Meridian will use the winter drill season to test targets which are, in
several cases, accessible only at this time of year. It will begin its 2008
drill campaign in mid January by drill testing the TAG anomaly.
Prime Meridian acquired lands on its Mid-Stage projects in Michigan earlier this
year, based upon interpretations of available government data sets and results
from Fugro's Geotem and Geotech's VTEM airborne systems. The TAG target, an
anomaly defined in the Geotem surveys as a strong, elliptical magnetic high with
coincident EM and a 5 milligal ground gravity peak, is one of the acquired
projects and Prime Meridian believes it is a compelling magmatic nickel-copper
target. In November, 2007, an induced polarization ("I.P.") survey was conducted
over the peak of the coincident magnetic, EM and gravity anomalies. The I.P.
data shows a strong chargeability high and resistivity low coincident with
magnetic, EM and gravity responses. Prime Meridian believes these anomalies may
represent a buried mafic intrusive (peridotite) contained within sulfidic slates
of the Michigamme Formation, thus presenting itself as a nickel-copper-PGM
target.
JAKE Nickel-Copper Target, Baraga Basin, Michigan
Following the completion of drilling at TAG and to take advantage of winter
access, Prime Meridian plans to drill test its JAKE nickel-copper-PGM project
located in the Baraga Basin of Michigan. This project is located approximately
12 miles from Rio Tinto's recently permitted Eagle nickel-copper-PGM deposit.
Outcrops of this gabbro intrusive were discovered by Prime Meridian in 2000.
This dike and sill complex intrudes into the sulfidic slates of the Michigamme
Formation along a major Midcontinent Rift structure. Subsequent ground
geophysical surveys conducted by Prime Meridian defined this intrusive as a
strong magnetic high with EM conductors.
Minimally, three additional nickel-copper targets in the Baraga Basin are
planned for testing after the winter drilling at Winterfire (described below).
All of these are high priority, coincident, magnetic, EM and gravity targets and
two of these are within 3 miles of the Eagle Deposit.
Winterfire, Minnesota
Prime Meridian has received the interpretations and selected drill targets from
the flying of GEOTECH's VTEM magnetic / electromagnetic system over the
Winterfire nickel-copper project area. During the 1970s a series of drill holes
intersected nickel-copper-PGM-gold mineralization over a 400m strike length at
Winterfire. Prime Meridian has acquired all lands containing this discovery as
well as additional lands covering newly developed targets from these surveys.
Prime Meridian will mobilize the drill rig to Winterfire during February to take
advantage of winter access.
