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) drill holes designed to test depth from
the 2014 Phase II, nine-hole Diamond drill program on the Pakeagama Lake
pegmatite. The assay and collar data for the 2 holes reported are
presented in Tables I and II.
The primary objective of these two holes was to test the deposit beneath
previously drilled holes. The intersection summaries for the two drill
holes outlined in Table I below have confirmed continuity of the zones
from the surface outcrop to depth. DDH PL-013-14 was drilled under hole
PL-001-13 (Phase I drill program) and tested the pegmatite at an average
depth of 60 metres below it. DDH PL-013-14 further defined the 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.

In Phase I drilling (2013) from 0 to 191m the hole was designed to
test Cs potential under pollucite-bearing aplite dyke at
surface and was stopped at the western margin of pegmatite.
In Phase II drilling (2014) from 191m to 304m the intent was
to complete the cross-section of the pegmatite.

(1) The intervals in Table I are drill intersection widths. There is
currently insufficient data to determine the true thickness of the
pegmatite.
(2) Li20 content in the CIZ is predominantly
associated with lithian micas and to a lesser extent (if any) in
spodumene. Li2O content in the Li enriched zones is predominantly
associated with spodumene.
n/a = Not applicable
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 event(s). 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.
“These drill holes were planned with a particular focus on depth and
confirm grade and geometry of our maiden resource estimate and also
should result in an increase of the deposit’s tonnage. These results
positively display that the pegmatite’s grade x thickness is persisting
with depth”, commented Trevor R. Walker, President of HLM. “We are
extremely pleased with these results from drilling at depth and are
enticed to test the pegmatite at depth with our future plans. We look
forward to the release of pending assay results from the final drill
holes of our Phase II Diamond Drill program that were designed to
possibly extend the strike length of the known deposit”.

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 AcmeLabs’ (A Bureau Veritas
Group Company) analytical laboratory in Vancouver, British Columbia 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; some assay results for
this program are still 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
