SUDBURY, Ontario--(BUSINESS WIRE)--
Houston Lake Mining Inc. (HLM.V)
Highlights:
-
Diamond Drill Hole (DDH) PL-011-14 intersected 1.68% Li2O
over 104 metre (m) from 9.1m to 104.75 m;
-
DDH PL-011-14 includes a 12.8 m wide high-grade lithium zone (Upper
Intermediate [UIZ]) averaging 4.01% Li2O from 35 to 47.8 m;
-
DDH PL-012-14 confirms the high-grade UIZ 25 m to the northwest;
-
Resource remains open to depth and along strike to the northwest
and southeast; and
-
Assay results pending from 7 remaining drill holes from the Phase
II Diamond Drill Program.
Houston Lake Mining Inc. (HLM.V), is a mining exploration
company that is specialized in rare-metals and is actively exploring for
lithium (Li), tantalum (Ta), rubidium (Rb) and cesium (Cs) by focusing
on its high-grade, 100% owned and optioned 4,032 hectare (9,963 acre)
PAK Rare Metals Project in northwestern Ontario, Canada. HLM is pleased
to announce the results of two (2) infill drill holes from the 2014
Phase II, nine-hole diamond drill program on the Pakeagama Lake
pegmatite. The assay and collar data for the 2 holes being reported are
presented in Tables I and II.
The primary objective of these two holes is to increase the level of
confidence in a portion of the inferred resource (see December 4,
2013 press release) with particular focus on the 1.17 million tonnes
grading 3.44% Li2O. The intersection summaries for the
two drill holes outlined in Table I below have confirmed continuity
of the zones along strike of the intersection in DDH-13-003 and
beneath the surface outcrop, and also defined bounding contacts with
host rock(s). Table I also summarizes the lithium, cesium, tantalum
and rubidium grades for the two drill holes by mineralogical zones
for the pegmatite intersections. The hole PL-012-14 intersection
confirms and extends the strike length of the lithium and tantalum
zones of the Pakeagama Lake pegmatite to the northwest.

The Upper Intermediate (UIZ), Central Intermediate (CIZ) and Lower
Intermediate Zones (LIZ) were previously described in the July 2, 2013
Press Release. Zones of sodic aplite are present in all holes and vary
in width from tens of centimetres to several metres, and contain
significant concentrations of Ta, Rb and Cs.
Noteworthy observations are that the NNE (footwall) boundary with the
metasediments is consistent and predictable while the SSW (hanging wall)
contact with the granite is somewhat erratic and complicated by granitic
blocks and rafts and appears to have been variably affected
(metasomatized) by the pegmatite intrusion events. The mineralized
pegmatite remains open along strike to the WNW and ESE, and at depth.
Granitic blocks/rafts mapped on surface appear to diminish with depth
and along strike in both directions.
The current strike length of the pegmatite as defined by surface mapping
and drilling remains at 290 m with an estimated width varying from 45 to
125m assuming sub-vertical orientation of the pegmatite body.
“These results with particular focus on the UIZ intercepts not only
confirm grade from our maiden resource calculation but should increase
the zone’s tonnage. These features of size and grade, combined with the
pegmatite’s low inherent iron (<.1% Fe2O3 {see June 11, 2014 press
release}) give HLM the confidence in its potential ability to
economically produce a technical grade quality spodumene product and/or
concentrate that could appeal firstly to the established specialty glass
and ceramics segment of the lithium market,” commented Trevor R. Walker,
President of HLM. “This could be possible in contrast to many others,
who would require a sizable capital investment in order to remove and
produce a low iron (Fe) product. We are pleased with these results and
look forward to releasing pending assay results in the near future from
the remaining drill holes on our Phase II Diamond Drill program.”

Due Diligence
All scientific and technical information in
this release has been reviewed and approved by Peter J. Vanstone,
P.Geo., the qualified person (QP) under the definitions established by
National Instrument 43-101. Under HLM’s QA/QC procedures, the diamond
drill contract specified NQ-sized drill core providing a 47.6 mm
diameter sample. The drill holes were oriented perpendicular to the
strike of the pegmatite and drilled continuously across it. Sample
security and chain of custody started with the removal of core from the
core tube and boxing of drill core at the drill site. The boxed core
remained under the custody of the drill contractor until it was
transported from the drill to the secure on-site Core Shack facility by
either the drill contractor or one of the Company’s designated
personnel. At the on-site Core Shack, core boxes were opened and
inspected to ensure correct boxing and labelling of the core by the
drill contractor, photographed and then re-closed. The core was stored
securely until moved into the Core Shack for processing. The company
geologists logged the core, and then marked and tagged it for sampling
and splitting. Each core sample was assigned a tag with a unique
identifying number. Sample lengths are typically one meter, but can be
less depending on zone mineralogy and boundaries. The Core was then
re-closed and shipped to the company’s off-site core splitting facility
in Sudbury, Ontario. Core marked for splitting was cut using a diamond
core saw with a mounted jig to assure the core was cut lengthwise into
equal halves. Half of the core was sent to an analytical laboratory for
quantitative analysis of select elements. The remaining half of the core
is retained and incorporated into HLM’s secure, off-site core library.
All samples were assayed by an ISO accredited laboratory. Sample blanks
along with tantalum, lithium, rubidium and cesium certified reference
material was routinely inserted into the sample stream in accordance
with industry recommended practices. Field duplicate samples were also
taken in accordance with industry recommended practices.
About the PAK Rare Metals Project
The PAK Rare Metals
Project lies close to the boundary between two geological sub-provinces
of the western Superior geologic province in northwestern Ontario and
hosts a rare metals pegmatite deposit. The deposit is an LCT (lithium-
cesium- tantalum) classified pegmatite. These rare types of deposits
have been the principal source of hard rock lithium, tantalum, rubidium
and cesium ores mined in the world.
HLM is actively exploring its 100% owned and optioned project which
contains the Pakeagama Lake pegmatite. The deposit is one of the highest
grade deposits in North America which has a current Inferred Resource of
6.89 million tonnes of 1.86% Li2O Eq. which has a
technical/ceramic grade spodumene with low inherent iron (below 0.1% Fe2O3).
Within the deposit, the pegmatite uniquely hosts an Upper Intermediate
Zone of 1.17million tonnes grading 3.44% Li2O. The pegmatite
has a 265m strike length with an estimated width varying from 45 to 125m
with a sub-vertical orientation. The resource remains open to depth and
along strike to the northwest and southeast. A 9-hole, 1,500m Phase II
diamond drill program was completed in late March 2014; assay results
for this program are pending and expected in the near future.
About Houston Lake Mining Inc.
HLM’s goal is to become a
fully integrated lithium and tantalum producer through the development
of the PAK Rare Metals Project in Ontario, Canada. The Company's
strategy is to take advantage of low-Fe ceramics/glass market as well as
the global shift towards electric/hybrid vehicles and high quality
consumer electronics by becoming a raw material supplier of the elements
required for the pursuit of sustainable energy and other applications in
ceramics/glass, high-tech electronics and metal alloys. Combined, HLM’s
Board of Directors and Management have over 300 years of finance,
exploration and mining experience to help to facilitate the Company’s
goal.
HLM has a total of 90,807,595 common shares issued and outstanding. For
