COLT RESOURCES INTERSECTS 5.28G/T AU OVER 15.39M, INCLUDING 9.99G/T AU OVER 3.43M AT ITS BOA FE GOLD PROJECT, SOUTHERN PORTUGAL.
Colt Resources Inc. has received final analytical results for five holes and
one trench from the continuing drilling and trenching campaign on its Boa Fe
gold project, located within the company's 100-per-cent-owned, 47-square-kilometre Boa Fe experimental mining licence (EML) in southern Portugal. The
Boa Fe EML is completely surrounded by the company's 100-per-cent-owned, 732-square-kilometre Montemor exploration concession.
The results from the Chamine and Ligeiro deposits are highlighted in the attached table.

Nikolas Perrault, president and chief executive officer of Colt, stated: "As promised, we are providing regular updates from our Boa Fe gold
project. We have broadened our drilling and trenching efforts to
include the Ligeiro deposit, and we are pleased to see continued
positive near-surface results. In the weeks ahead, we also expect to
begin to report results from the nearby Casas Novas deposit as we
further expand the campaign currently under way which is designed to
confirm and increase the potential of this very exciting gold project."
Program strategy
Gold mineralization has been identified in several deposits along a
shear zone that extends over approximately 30 kilometres along strike. Previous shallow drilling was focused on the highest-grading portions of gold anomalies that closely follow the regional
shear. The mineralization style interpreted in the current model
is associated with shears at low angle to the regional shear
direction (S1, S2, T and R) developed due to contrasts in competency
between granitic and silica-rich units and pelitic schist within the
main regional shear zone. Where conjugate sets of shears occur (which are S1
and S2 with T), the best development of mineralization occurs. Conjugate
sets of mineralization may occur anywhere within the regional shear
zone and are not restricted by depth.
Hole BFCH-12-009 is the last hole in a fence line drilled along section
line 6400N at Chamine and was drilled in the reverse direction to
previous drill campaigns to get better definition of the high-grade
zone with respect to the low-angle shear model (see press release
dated Feb. 28, 2012) and fill in a gap interval in a neighbouring
previous hole which was not sampled. The results correlate with the
current model for this section within a plus-or-minus-three-metre tolerance.
Colt will continue to test its current ideas on structural
interpretation against previous models and aim to finalize a 3-D model
that incorporates the concept of conjugate shear orientations
reinforcing each other and leading to higher grades of gold
mineralization. The company will continue its aggressive advanced-stage
exploration campaign consisting of a combination of vertical and
inclined drill holes positioned to confirm previous drilling results at
Casas Novas, Ligeiro, Bracos and Banhos deposits, and investigate the
gaps between Chamine-Casas Novas and Chamine-Ligeiro to increase
resource potential. Results currently being interpreted from
geophysical exploration (resistivity and seismic orientation surveys
across Chamine) will greatly assist in advancing targets in the gap
areas. High-priority regional targets identified through field
prospecting will also be tested. The results of this phase of work
will form the basis for an initial NI 43-101-compliant resource
estimate to be prepared later in 2012, covering several previously
drilled gold-bearing deposits within the Boa Fe EML.
Minimal drilling has been performed to test depth extensions below an
average of 100 metres or along strike between known mineralized
deposits. Given the shear-zone style of mineralization and extensive
gold anomalies in soils, there is good potential to build upon previous
work that supported several non-NI 43-101-compliant resource estimates
that range from 150,000 ounces to 550,000 ounces of gold as defined over the period
from 1991 to 2008 (see press release March 7, 2011).
Quality assurance/quality control
Drill sample intervals are reported as metres downhole and, as such,
do not represent true widths of mineralized intersections. All drill
core is transported by company personnel from drill site to a nearby
secure storage facility for logging and sampling. Sampling intervals
are defined after core logging and determination of probable high-grade
zones based on visible mineralization and favourable structure. One-half of the core is sent for analysis, while the other half is retained
in the core boxes for future reference.
Trench samples are collected from bedrock exposed at the base of a
trench excavated by a backhoe, and cleaned and mapped prior to sample
collection. Trench channel samples are collected using hammer and
chisel, and are generally two metres long with an average width of
10 centimetres. Channel samples are bagged on site and sent for
analysis.
All samples are sent by courier to ALS Chemex's facility in Seville,
Spain, where they undergo sample preparation. The resulting pulps are
shipped by ALS to its laboratory in Romania for gold assay and
routine ICP multielement analysis. Gold analysis for all samples is
done via method Au-AA23 (gold by fire assay and AAS, 30-gram nominal
sample weight). The detection limit for this method is five parts per billion. For every
sample with gold values over three parts per million, the pulp is reanalyzed by method Au-GRA21 (gold by fire assay and gravimetric finish, 30-gram nominal sample
weight). The detection range for this method is 0.05 to 1,000 parts per million.
A set of standards and blanks has been inserted by Colt into the drill
sample stream on a regular basis in addition to the laboratory's own
internal quality assurance/quality control standards and duplicates. Quality assurance/quality control results to date are well
within the accepted norm.
