HLM Identifies strong Rubidium grades up to 0.53% Rb20 over 14

FSC / Press Release 
HLM Identifies strong Rubidium grades up to 0.53% Rb20 over 14 meters on the PAK
Rare Metals Project in Northwestern Ontario 
Sudbury, Ontario CANADA, April 24, 2013 /FSC/ - Houston Lake Mining Inc. (HLM -
TSX Venture),is a mining exploration company which is actively exploring for the
rare metals lithium, cesium, tantalum, and rubidium by currently focusing on its
100% owned and optioned PAK Rare Metals Project in northwestern Ontario, Canada.
 HLM is pleased to announce some of the remaining results from its 2012 Channel
Sample Program on the Pakeagama Lake pegmatite, located at the 1,792 hectare
(4,424 acre) PAK Rare Metals Project. 
In September 2012, Peter J. Vanstone, P.Geo. the qualified person (QP) for the
project, conducted a 91 sample channel sampling program on the Pakeagama Lake
pegmatite in order to confirm historical results and to add additional channel
samples while further sampling by distinct geologic zones. In addition to the
high grade lithium oxide results up to 4.74 Li20 over 15 meters, and strong
tantalum oxide results up to 192ppm Ta205  over 14 meters reported by HLM in
January, 2013, the program has also identified rubidium (Rb) oxides in a
distinct pegmatite zone as discussed below: 
Central Intermediate Zone (CIZ) 
CHANNEL      AZIMUTH   LENGTH(M)   Rb205(%) 
 PAK-12-CH001R      226       14.00       0.53 
including                 5.00       0.62 
also                 1.00       0.81
 PAK-12-CH007R      222        6.00       0.67 
including                 2.00       1.17
  PAK-12-CH019      213        9.70       0.65 
including                 6.00       0.68 
also                 1.00       0.96
Table 1
The Central Intermediate Zone (CIZ) is located in the upper portions of the
pegmatite. It is in contact with both the Upper Intermediate Zone (UIZ) and
Upper Wall Zone, and persists to the southeast edge of the outcrop where it is
believed the pegmatite continues under the till cover. Channel 19 is located in
the central portion of the exposed CIZ where the zone consists predominantly of
grey K-feldspar with minor lithian mica + quartz alteration. To the southeast,
the K-feldspar is altered to a mica+quartz mixture and was sampled by Channel 7R
(highest rubidium grades found to date in the exposed pegmatite).  Samples from
this channel consisted of similarly sized fragments of randomly oriented
K-feldspar with varying degrees of mica+quartz alteration.  In the adjacent area
to the northeast of Channel 7R, the alteration consists of K-feldspars more or
less completely replaced with a lithian mica + quartz mixture where veinlets and
patches of lepidolite occur. This altered zone, which was sampled by Channel 1,
contains strong tantalum and rubidium grades over a significant width. 
When considering the CIZ as outlined in Table 1, the distance between channels
19 and 1 is approximately 35m. Overall, this zone has an exposed surficial
expression of approximately 100m in length and remains open to both the
southeast and northwest. 
The Pakeagama Lake pegmatite does not currently have a resource, however the
mineralogy of the CIZ and the presence of lepidolite is similar to the CIZ
described in the Tanco pegmatite. The Tanco pegmatite is located southwest of
the PAK Rare Metals Project in southeastern Manitoba and has recently ceased
mining production from their CIZ zone. 
"In addition to the high-grade lithium results of up to 4.74 Li20 over 15
meters, and high tantalum results of up to 192ppm over 14 meters encountered and
reported in January, these strong rubidium grades from the program entrench the
Pakeagama Lake pegmatite as a leading high-grade, multi-element exploration
target for rare metals in North America.  Furthermore, within the next three to
five weeks, HLM will begin receiving assay results from our Phase I, 1,000-meter
diamond drill program that commenced in March." said Trevor R. Walker, President
of HLM. 
Due Diligence 
All scientific and technical information in this release has been reviewed and
approved by Peter J. Vanstone, P.Geo. who is the qualified person (QP) under the
definitions established by National Instrument 43-101.  Under HLM's QA/QC
procedures, channels are cut with a motorized circular diamond saw, and are 4 cm
wide and 10 cm deep.  The channels are oriented perpendicular to the strike of
the pegmatite internal mineralogical zones and are cut continuously across the
zones.  The samples are removed using a hammer and chisel.  The length of a
channel is determined by the width of the pegmatite zone. Offset channels are
cut where deemed appropriate.  Sample lengths typically are 1 metre but can be
less depending on zone mineralogy and boundaries.  Samples are described, placed
into a poly sample bag with a numbered sample tag and then shipped to the assay
lab for quantitative analysis for select elements.  All HLM samples are
currently being assayed by Activation Laboratories Ltd. with all samples being
delivered to their Thunder Bay facility.  Sample blanks along with tantalum
certified reference samples and lithium-rubidium-cesium standard samples are
routinely inserted into the sample stream in accordance with industry best
practices.  At the completion of each program, approximately 10% of the channel
sample pulps are submitted to a secondary ISO certified laboratory for assay
