MONTREAL,
Jan. 30, 2013 /PRNewswire/ - Colt
Resources Inc. ("Colt" or the "Company") (TSXV: GTP) (FRA: P01)
(OTCQX: COLTF) is pleased to announce that it has received positive
metallurgical results from testwork performed on representative
samples taken from the Tabuaço Tungsten Project (São Pedro das
Águias), as well as results for eleven holes from its exploration
drilling campaign at the nearby Tabuaço-Aveleira gap, Aveleira and
Quinta targets, all located in the Armamar‐Meda concession in
northern Portugal. Colt is
awaiting final approval for the "Tabuaço" Trial Mining License,
expected to be granted later in Q1, 2013, which will include the
deposits reported to date together with the surrounding area
believed to host the most significant upside potential.
As part of its ongoing efforts to advance the
Tabuaço deposit towards production, the Company had previously
submitted a 522 kilogram representative sample of metallurgical
drill core to a Chinese metallurgical services provider for process
testing. A final report of this investigation has been issued by
the Chinese metallurgical services provider, demonstrating a
process flowsheet that includes flotation followed by acid leaching
achieved 87.2% overall tungsten recovery into a final concentrate
containing 70.65% WO3 from an ore sample containing
0.64% WO3. The Company is very pleased with the results
of this test work as it demonstrates a high tungsten recovery, by
world standards, into a premium grade scheelite concentrate. The
Company plans to conduct pilot mill testing on approximately 20
metric tons of ore from Tabuaço later this year. The Company also
intends to investigate further the potential production of fluorite
concentrate as a possible by-product from the deposit.
Nikolas Perrault,
President and CEO of Colt, stated, "These final metallurgical
test results further demonstrate the potential to develop a
successful tungsten mining operation at Tabuaço. Our work to
complete a preliminary economic assessment (PEA) has commenced and
we intend to conclude this work during the second quarter.
Discussions are currently ongoing and advancing as we continue our
efforts to identify a suitable joint venture partner for Tabuaço so
as to deliver on our promise to focus on our gold projects while
maintaining the full benefits of part ownership of a solid revenue
generating asset with lots of blue-sky."
Mr. Perrault continued, "Our exploration work
designed to test the upside potential of this area continues to
yield positive results. Our geological team has identified
several zones of mineralization based on mapping and geochemistry
and these results confirm that our predictive model is
robust".
Colt is pleased to announce the following
results from our ongoing exploration drill program to test
extensions of the previously reported resources at the Tabuaço and
Aveleira deposits.

Drilling Summary:
Holes DHT-79, -80, -81, -86 and -87 were all
drilled at the Aveleira skarn tungsten deposit, first discovered by
Colt through drilling in February
2012. DHT-79 was drilled 64 metres East-Northeast
(down-slope) from mineralized hole DHT-71. It only intersected the
Lower skarn horizon, while the Main (Upper) skarn horizon is
believed to have been eroded away at this low topographic
level. Vertical holes DHT-80 and -81 were collared as to test
depth extensions into the mountain West-Southwest of the first line
of holes drilled at Aveleira, namely at around 70 to 85 metres from
mineralized holes DHT-53, -70 and -71 respectively. Both holes
DHT-80 and -81 intersected mineralized horizons. Inclined
holes DHT-86 and DHT-87 were drilled in order to target skarn
mineralization occurring in the intervals between DHT-70/DHT-81 and
DHT-71/DHT-85 respectively. Both holes intersected mineralization,
as shown above in Table 1.
With these holes, Colt has mostly outlined the
lateral limits of the Aveleira deposit, which seems therefore not
to extend much at depth into the mountain. Future drilling at
Aveleira will therefore consist essentially of infill grid drilling
in order to allow outlining of an indicated resource.
Holes DHT-77, 78 and 88 were all drilled in the
Gap between Tabuaço (São Pedro das Águias) and Aveleira skarn
tungsten deposits, where Colt first discovered concealed tungsten
skarns through drilling in July
2012. DHT-77 was drilled roughly half-way between
mineralized hole DHT-75 and barren hole DHT-73, having confirmed a
further 60m northerly extension of the mineralization previously
intersected by DHT-75. Drill hole DHT-78 was positioned 80m due
South from DHT-72 (the discovery hole in the Gap) having confirmed
a southerly extension of the Gap skarns to as close as 40m with
regards to the São Pedro das Águias resource area. DHT-88 was
drilled a further 80 metres NW of DHT-83, and proved to be the best
mineralized hole drilled thus far in the Gap, with two distinct and
well separated, thick and richly mineralized skarn horizons, much
like at the São Pedro das Águias deposit and the best portions of
the Aveleira deposit.
The skarn tungsten mineralization found by Colt
in the Gap between the São Pedro das Águias and Aveleira deposits,
and tested so far by a total of seven diamond drill holes (five
mineralized and two barren), extends for a Northwest-Southeast
strike extent of 275 metres, and a yet unknown lateral (down-dip)
extent into the mountain and underneath the outcropping granite.
The fact that the last (North westernmost) hole drilled in this
zone turned out to be the best mineralized hole leaves open good
potential for finding further significant mineralization, once
drilling is resumed to test the Northwest extent of this skarn
zone. This untested area comprises the >300 metre zone between
DHT-88 and the Aveleira deposit.
Holes DHQ-01, -02 and -03 were drilled at the
Quintã zone NW of the Aveleira deposit, to test for depth extents
of the skarn tungsten mineralization previously mapped and sampled
on outcrop at the southern slope beneath the Quintã village. All
these three holes were collared on the same approximate location,
at around 225 metres NNW of the Quintã skarn tungsten outcrop,
however were drilled with distinct orientations. DHQ-01
(-45o) aimed at the Quintã skarn outcrop with a bearing
of N160o, but it failed to intersect thick and well
mineralized skarns as shown in the outcrop, but rather a number of
narrower skarn horizons. DHQ-02 (-45o) was
oriented to bearing N200o, in order to test a possible
westerly deviation of the skarn from the Quintã outcrop; in fact it
had two skarn intercepts but with modest grades (<0.2%
WO3). DHQ-03 (vertical) again intersected a number
of narrow and poorly mineralized skarn horizons.
This first drilling ever carried out at Quintã
therefore failed to confirm a significant depth extension of the
thick and rich skarn tungsten outcrop into the mountain. The
acquired drilling and surface data will need to be re-assessed in
order to guide future exploration drilling, perhaps closer to the
outcrop and/or further to the West underneath the granite.
Results from DHT-88 show that the discovery area
is not closed off to the north-west and initial results of drilling
suggest the potential for mineralization to extend beyond the
previous reported resource area (Press Release - September 5, 2012). Drilling down-dip is
also planned to test the contact relationship between the
mineralized skarns and the granite located to the south-west of
Tabuaço (São Pedro das Águias).
Quality Assurance / Quality Control (QA/QC)
Sample intervals are reported as both metres (m)
downhole and as true thickness, which have been calculated by Colt
Resources using cross-sectional interpretation of the mineralized
intercepts in three dimensions. The actual dip of the skarn
controlled mineralization is generally shallow.
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 scheelite content by examination under
short‐wave UV‐light. One half of the core is sent for analysis,
while the other half is retained in the core boxes for future
reference.
Samples are sent by courier to ALS Laboratory
Group, Seville, Spain. Samples are
analyzed for W and Sn using a metaborate fusion followed by XRF.
Assay results for tungsten are reported by the laboratory as W%.
WO3 values are calculated using a conversion factor of
1.2611.
A set of standards, duplicates and blanks is
inserted by Colt into the sample stream on a regular basis in
addition to the laboratory's own internal QA/QC standards and
duplicates. QA/QC results to date are well within the accepted
norm.
Correction:
Colt would like to correct an error in Press
Release dated December
20th, 2012. In Figure 2: "3D view of the
Chaminé deposit including results of the first 2 deep drillholes
and including drill traces of all Colt drillholes reported to
date", drillhole BFCH-12-037 was mislabelled as BFCH-12-039 and
incorrectly plotted dipping to the North. The corrected
Figure 2 is as follows.
