TORONTO, Sept. 29, 2011 /CNW/ - Celtic Minerals Ltd. ("Celtic" or the "Corporation") is pleased to report that it has completed a National Instrument
43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") technical report (the "Report") on its Dawson Gold project ("Dawson") in south-central Colorado prepared by Isobel Wolfson, P.Geo. on
behalf of the Corporation and dated September 27, 2011. Isobel Wolfson
is a qualified person and is responsible for all items in the Technical
Report, but according to NI 43-101 and 43-101CP, she is not considered independent as Ms. Wolfson was a previous consultant to the
Corporation from which the majority of her income derived at such time.
The Report is available under the Corporation's profile on SEDAR and
will be on the Company's website, celticminerals.com.
Celtic's Board of Directors is pleased to note that the site visit and
the independent sampling support the historical exploration records of
Dawson Project Field Office
Celtic announces that it has opened a field office in Cañon City, CO to
oversee the operational logistics of the project. Celtic is pleased to
announce that the corporation has engaged Mr. Jim Javernick as project
coordinator. Mr. Javernick has several years' experience working on
the project and is located in Cañon City, Colorado. Mr. Javernick has
been given a mandate by the Board of directors to investigate the most
expedient way of bringing the Dawson Project into production. However
there can be no guarantee that the Corporation will achieve production
at the Dawson Project.
Celtic has initiated permitting and additional staking on the project.
About the Dawson Gold Property
The Dawson Property, located in south-central Colorado, hosts gold and
base-metal mineralization in a Proterozoic-age, metamorphosed
exhalative zone of quartz-biotite ± garnet gneisses. Dawson is a joint
venture between Celtic and Uranerz USA Inc. ("UUS Inc."), a wholly owned subsidiary of Cameco Gold. In 1999, UUS Inc. elected
to dilute its then 30% interest in the project. Although a formal
dilution calculation has not been completed, Celtic currently holds at
least 70% interest in the project. The Property is subdivided into
several administrative "Segments", two of which contain drill-tested
zones of gold and base-metal mineralization.
The Dawson Segment
Mineralization in the Dawson Segment consists of 3 main zones which
formed the basis of historical mineral resources. Based on the Uranerz
Report (defined below), the Dawson Segment contains an historical "gold
resource" of 263,000 short tons at a diluted (to 5 feet minimum
thickness) grade of 0.460 ounces gold per short ton (opt).
The most recent resource estimations for the Dawson Segment were
completed in 1991 and 1992. The following estimation method is taken
from the 1991 Annual Report of UUS Inc. by C. Mettler (1991 Annual
Report; Project 7355: Dawson. Uranerz USA Inc. Report, 1992) (the "Uranerz Report").
For the Dawson Segment, resources were calculated using a method whereby
the influence around diamond drill intersections was calculated by the
inverse distance squared method ("IDS") on longitudinal sections oriented parallel to mineralized zones
constrained by geological and geochemical boundaries. Each longitudinal
section was subdivided into square 25' x 25' (625 square feet) cells.
Where there was more than one gold assay for a sample interval, the
assays were averaged. Gold assays were uncut. All gold values below
0.007 ounces per short ton ("opt") were set to 0.001 opt. Intervals not sampled but identified within
the mineralized zones were given a blank gold value.
Gold grades were composited within sample intervals to give a weighted
average gold grade. The true thickness ("T") of each zone in drill core was calculated by multiplying the sine of
the average foliation angle of the sample intervals by the entire
sample length. The average grade was multiplied by the true thickness
to produce a "grade-thickness" ("GT") value for each composited interval.
Using a search radius of 125 feet, up to 5 GT values were used to
calculate an average GT and T (true thickness) for each cell. Those
blocks with GT values ≥ 1.0 were used in the resource calculations.
An average tonnage factor of 12.4 cubic feet per short ton (equivalent
to a specific gravity of 2.58) was used; this was based on specific
gravity tests on eight "representative samples".
For each mineralized zone, the total of the number of cells above the
"cutoff" (GT values ≥ 1.0) was divided by 625 square feet (cell area)
to give an area of the zone. The average true thickness was the sum of
the T divided by the total number of cells. The volume of the zone was
calculated as the area multiplied by the average thickness. The tonnage
of the zone was calculated by dividing the volume by the tonnage
factor. The average gold grade for each zone was calculated by the sum
of GT divided by the sum of T.
The minimum required thickness of each zone was 5 feet. If the zone was
less than 5 feet, it was diluted with material at zero gold grade and
2.58 specific gravity to produce a zone with a thickness of 5 feet.
The historical estimates of "gold resource" is a category other than the
ones set out in Sections 1.2 and 1.3 of NI 43-101. Such categories
cannot be compared to current mineral resources or mineral reserves as
defined in Sections 1.2 and 1.3 of NI 43-101 as there have been no work
to verify and classify such historical estimates. The historical
estimates are not compliant with NI 43-101 and should therefore not be
The Windy Gulch Segment
The Windy Gulch Segment contains 3 areas of gold mineralization.
Calculations on the "best defined" area indicated a "preliminary gold
resource" of 33,600 short tons at 0.405 ounces per short ton gold, with
an average true thickness of 8.7 feet. The block was defined by 6
surface diamond drill holes, 3 underground drill holes and several
surface channel samples. These figures are taken from UUS Inc.'s 1990
annual report by C. Mettler (1990 Annual Report; Project 7355: Dawson
Uranerz USA Inc., March 1991) (the "Uranerz 2 Report"). No description of estimation methods or assumptions were reported.
The historical estimates of "preliminary gold resource" used in the
Uranerz 2 Report is a category other than the ones set out in Sections
1.2 and 1.3 of NI 43-101. Such categories cannot be compared to current
mineral resources or mineral reserves as defined in Sections 1.2 and
1.3 of NI 43-101 as there has been no work to verify and classify such
historical estimates. The historical estimates are not compliant with
NI 43-101 and should therefore not be relied upon.
Recent exploration programs were carried out from the mid-1970s to early
1990s and included about 25,549 metres of diamond drilling in 134
holes. As part of the data verification process, the half-cores of 4
mineralized drill hole intercepts identified in historical drill logs
and industry reports were collected for gold analysis by screened
metallics fire assay. Three of the four assays showed reasonably good
correlation with original assays; the fourth sample intercept assayed
higher (sample 272719) than an original assay, which may be due to the
nugget effect. The site visit and independent sampling support the
historical exploration records of the Property. The historical data
appears to be adequate for the purpose of the technical report, which
is to report on the geology, mineralization and historical exploration
of the property.
The above technical information regarding the Dawson Property was
reviewed but was not verified by Ms. Isobel Wolfson, P,Geo. Ms.
Wolfson is a geoscientist with over 20 years of experience as an
underground mine geologist in volcanogenic massive sulphide ("VMS") style base metal deposits. She has participated in numerous mineral
resource estimates and is familiar with both the information required
and the processes used to produce a mineral resource estimate, both in
Canada (using NI 43-101) and Australia (using the JORC Code).
Celtic has relocated the head office to Toronto, ON Canada, and has
closed the office in Grand Falls-Windsor, NL. A field office will be
set up in St. John's, NL in the near future to oversee Celtic's
Labrador Nickel project.
A qualified person has not done sufficient work to classify the Dawson
historical estimates as current mineral resources or mineral reserves
and were compiled before NI 43-101 came into effect and are not in
compliance with NI 43-101. The historical estimates of "gold resource"
and "preliminary gold resource" are categories other than the ones set
out in Sections 1.2 and 1.3 of NI 43-101. Such categories cannot be
compared to current mineral resources or mineral reserves as defined in
Sections 1.2 and 1.3 of NI 43-101 as there have been no work to verify
and classify such historical estimates. The historical estimates are
not compliant with NI 43-101 and should therefore not be relied upon.
Finally, the Corporation does not make any representation or warranties
as to the accuracy of such estimates. Isobel Wolfson, M.Sc,, P.Geo is
the qualified person who has reviewed and verified the technical
contents of this news release.
