VANCOUVER, BRITISH COLUMBIA (TSX VENTURE: KRR) has completed a
10 hole, 1485 meter diamond drill program on the Minnie Moore
property and is pleased to announce details regarding the Minnie
Moore epithermal silver-gold discovery, including preliminary
results from the August 2007 trenching program. The Minnie Moore
discovery shares a number of characteristics with epithermal veins
from the Republic District of Washington State, including a similar
age, an association with Eocene structural activity, and similar
textures, gangue and sulfide mineralogy, and geochemistry.
Partial results have been obtained from the August 2007
trenching program at the Minnie Moore zone. Overlimit silver assays
are not yet available, nor are fire assay results for high gold
samples. Subsequent trenching during October 2007 more fully
exposed the Minnie Moore zone for detailed sampling and extended
the true width of the zone beyond what is represented by the August
trench samples. Results from this additional sampling are similarly
unavailable, however in response to considerable shareholder
interest, the Company is releasing information available to date.
Additional assay results will be released when available.
Where exposed by trenching, the Minnie Moore vein occurs within
a zone of faulting, dyking and veining that measures up to 15
meters in width. The vein itself has a true width ranging from 2.9
to 8.5 meters, and is bounded on the east and west by strong,
north-northeast trending, vertical to steeply west-dipping faults.
Eocene dykes within the wider fault zone are strongly argillic
altered and locally cut by chalcedonic quartz veins.
The Minnie Moore vein has been stripped completely over an 8
meter by 13 meter area in Trenches 1 and 3 (which have now been
merged together by subsequent excavation). It is a well-defined
breccia vein comprised of intensely silicified limestone and
siltstone that is cut and cemented by vuggy quartz and
quartz-carbonate veinlets and breccia matrix. Sulfide content is
low, only locally exceeding 5%. Sulfides consist primarily of
pyrite, with lesser chalcopyrite, sphalerite, galena, tetrahedrite,
and ruby silver. Native gold has been seen in thin section and in
hand specimen. Trace element geochemistry shows elevated mercury,
arsenic, antimony and selenium.
Thirty meters south of the Trench 1 and 3 exposure, Trench 2
uncovered a 5 meter wide by 7 meter long segment of the Minnie
Moore vein. The Trench 2 vein segment is truncated by faults on the
north, south and east. Additional trenching further south failed to
penetrate the overburden. The potential for the system to continue
on-strike to the south remains untested. Trenching on strike to the
north of Trenches 1 and 3 uncovered a thick, moderately magnetic
Eocene sill. Drilling has successfully intersected the favorable
Brooklyn stratigraphy at depth beneath the sill.
Outcrop in the vicinity of the Minnie Moore zone is sparse, with
overburden depth ranging from less than 1 meter to greater than 5
meters. An excavator was employed in the trenching program to
remove overburden to a solid bedrock surface. Trenches were then
hand shoveled and swept clean before mapping and laying out for
sampling. Sampling consisted of continuous representative chips
collected across the true width (or partial true width where the
zone was not fully exposed at the time of sampling) of the
mineralized zone. Sample interval was generally 1 meter. In
Trenches 2 and 3, two parallel lines of samples were collected
across the mineralized zone. In each trench, these 2 lines of
samples were separated by 2-3 meters along the strike of the vein.
Samples were shipped to Acme Analytical Laboratory in Vancouver for
preparation and analysis for gold and a multi-element suite, by
ICP-MS analysis. Subsequent fire assay is being done on samples
returning greater than 1 g/t gold and those exceeding the ICP
detection limit of 100 g/t for silver. A quality control-quality
assurance program was implemented, including field duplicate
samples and company inserted blanks and standards at regular
intervals.

As previously released, select grab samples from TR07-3 have
returned results to a maximum of 4500 g/t Ag (131.4 oz/t Ag), 6.04
g/t Au (0.18 oz/t Au), 0.78% Zn, 0.58% Pb and 0.25% Cu (NR Oct 29,
2007).
Scott Geophysics was contracted to complete a ground
magnetometer survey over the area, during October 2007, to aid in
mapping the position of fault zones and (magnetic) Eocene
intrusives. The results of the ground magnetometer survey have been
received. Several pronounced, elongate, north-, northeast- and
northwest- trending magnetic low anomalies were delineated in the
vicinity of the Minnie Moore epithermal zone. All of these
anomalies exceed several hundred meters in strike length. They are
interpreted to represent major fault zones, such as the one
intimately associated with the Minnie Moore vein.
A soil geochemical survey was also completed over the same grid
as the ground magnetometer survey, with a total of 989 samples
collected at 12.5 meter intervals on 50 meter spaced lines. Results
are pending.
Drill core logging from the recent drill program has been
completed and core sawing and sampling is underway. To date, a
total of 301 drill core samples from holes 07-1 through 07-8 have
been shipped to Acme Analytical Laboratory in Vancouver for
preparation and analysis. Core sawing is underway for holes 07-9
and 07-10. An additional 120 drill core samples will be shipped
from holes 07-9 and 07-10 upon completion of sawing.
Drilling was done by More Core Drilling of Stewart, B.C. Core
was NQ2 size. A quality control-quality assurance program was
implemented, including company inserted blanks and standards at
regular intervals. The company anticipates a lengthy delay in
obtaining results from the recent diamond drill program, due to the
current backlogs at all Canadian assay laboratories.
Photographs from the recent trenching and drilling program have
been posted to the company website (www.kettleriver.com). Detailed
trench maps will also be posted when they are available. Linda
Caron, M.Sc., P.Eng. is the Qualified Person under NI 43-101 who
