"This final batch of Granduc assay results once again confirms the continuity of
copper mineralization over a 1.2 km strike length," stated Mr. Mike Sylvestre,
President & CEO of Castle Resources. "The overall success of the program
continues to reinforce the potential resource upside of the Granduc. With all
2011 drill results completed, Castle is now focused on completing an updated NI
43-101 resource estimate, currently being compiled by SKR Consulting
(Vancouver), to be released later this month."
Castle completed a 58 hole expansion drilling program in 2011 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 the 2011 drilling was focused on defining the potential copper
mineralization in the South Zone. As previously press released, South Zone
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 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. Part way through the drilling program,
EcoTech Laboratories were taken over by ALS Chemex. Preparation of the pulps
continued at the EcoTech prep facility, but all pulps were then sent by courier
and all analytical work was conducted by ALS Chemex at their lab facilities in
Vancouver. The rejects are stored at the EcoTech prep facility in Stewart. All
samples were prepared through an aqua-regia digest and analysed 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.
Brad Leonard, P. Geo., Castle's Exploration Manager, is the Qualified Person

Instrument 43-101) discussed in this press release, and has reviewed this press
release. Castle implemented a QA/QC protocol for all its exploration and diamond
drilling program on the Granduc.
