Castle Resources Reports Assays for Hole 36 at the Granduc Copper Project
November 23 2011 - 6:00AM
Marketwired
Castle Resources Inc. (TSX VENTURE:CRI) ("Castle" or the "Company")
is pleased to announce the final assay results for GD11-36 at the
Granduc Copper Project located near Stewart, B.C.
"We are very excited by the widths and grades of this sizable
block," stated Mr. Brad Leonard, Castle's Exploration Manager.
"Assays from GD11-36 clearly demonstrate that the South Zone
carries significant copper resource upside and provides evidence
that Granduc mineralization is expanding as we continue our
exploration program to the south."
Hole 36 is the most significant hole to date on the Granduc
South Zone. It was collared on the glacier at an elevation of 725
meters in the central part of the South Zone and successfully
intersected copper mineralization between 587 and 351 meters above
sea level (approx. vertical elevation).

Castle has completed a 60+ hole step out and expansion drilling
program with a focus on testing potential down dip zones identified
by SRK Consulting as 'exploration potential' and targeting
potential non-compliant NI 43-101 historic copper resources down to
sea level (see SEDAR July 4, 2010). In addition, a large percentage
of this year's drilling was focused on defining the potential
copper mineralization in the South Zone and as previously press
released drill core assays results clearly show high grade
mineralization extending over 600 meters on strike and to the south
of the Main Zone (see press release dated July 27, 2011) and 600
meters down dip to sea level (see press release dated Sept 8,
2011). It is increasingly evident that Granduc mineralization
remains open at depth beneath sea level and open along strike to
the south, beyond Castle's most southern step-out hole.
QA/QC Protocol
Castle Resources implemented a QA/QC protocol for all its
exploration and diamond drilling program on the Granduc. The
drilling contractor was Morecore Drilling Services and core
diameter was a combination of NQ and thin wall NQ, enabling the
possibility for at least two step-downs if ground conditions should
require it. All drill hole locations were spotted using a hand-held
Garmin GPS receiver with a 2m to 6m accuracy. Following drill hole
completion, all drill hole collar locations were surveyed and
reported by a certified BC land surveyor. Core was delivered to the
secure Core Shack facility located on the property. In addition to
recovery and RQD (Rock Quality Designation) data, geologic
parameters including lithology, alteration, presence and
identification of sulphide mineralization along with other geologic
parameters are noted and recorded. Core was marked in one meter
intervals for splitting, sampling and assaying, unless geologic
data indicate a shorter sample interval. Prior to splitting, all
core was photographed. Core splitting was done with a diamond core
saw or by manual splitter and 1/2 of the drill core was submitted
to EcoTech Laboratories (part of the Stewart Group of Companies), a
certified sample preparation facility located in Stewart, B.C.,
where samples were crushed, pulped and screened to 100 mesh. The
pulps were then sent by courier to the main EcoTech laboratory
facility in Kamloops, B.C. for assay, while the rejects are stored
at the EcoTech prep facility in Stewart. All samples were analysed
through an aqua-regia digest and analysesd through a 35 element
ICP/MS package and gold fire assay with an Atomic Absorption (AA)
finish. All sample over-runs through the ICP package automatically
were fire assayed with an AA finish.
A QA/QC protocol was followed for the drill core sampling
program, which involved inserting sample blanks and standards at
regular intervals into the sample stream. Blanks were inserted at
the nominal rate of 1 in every 35th sample as well as after a
sample which contained significant visible sulphides. Sample
standards were inserted at the nominal rate of 1 in every 20th
sample (alternating between OREAS_93' OREAS_95 and OREAS_153a).
Every 20th sample on odd multiples was selected as a "referee
sample" whereby instructions were given to the prep facility to
prepare 2 pulps, analyze one and keep the second to be sent to
another credited laboratory for verification of results. Three
duplicate samples were selected per hole, located in a mineralized
zone to assure continuity of higher grade results, where half the
core was quartered and sent as a separate sample. Sample tags made
of sturdy Tyvek were inserted into each plastic sample bag and
securely sealed. The sample number along with the sample interval
was recorded on the drill log. The sample interval was recorded in
the sample tag book. A 3rd sample tag was stapled into the core box
at the end of the sample interval. All core is currently and
securely stored in the remote camp location, or at the company's
secure core logging facility in Stewart.
