HLM Identifies Further High Grade Lithium at Surface Through New Channel Sampling up to 4.46 Li2O over 8 Meters on the PAK Rare Metals Project
Sudbury, Ontario (FSCwire) - Houston Lake Mining Inc. (TSX.V: HLM), 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 from its 2014 Channel Sample Program on the project. In August 2014, HLM conducted a 45 sample program in order to confirm and increase confidence with additional surficial sampling in the Upper Intermediate Zone, and to update historical information on the Lower Intermediate Zone at the Pakeagama Lake pegmatite. The assay data for the 3 channels being reported are presented in Table I as seen below.

| 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. 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. | |||||||||
| CH PL-010, 011, 012, 013-14 | Designed to confirm historical results and provide data that was not available in the maiden resource estimate for the LIZ zone at surface in the northeastern portion of the pegmatite deposit. | ||||||||
| Channel/Zone | Width (m) | Li2O (%) | Cs2O (%) | Ta2O5 (ppm) | Nb2O5 (ppm) | SnO2 (ppm) | Rb2O (%) | ||
| PL-010-14 / LIZ | 13.00 | 1.34 | 0.018 | 101 | 61 | 425 | 0.29 | ||
| including | 6.00 | 2.64 | 0.017 | 50 | 34 | 79 | 0.33 | ||
| including | 6.00 | 0.48 | 0.018 | 181 | 103 | 590 | 0.27 | ||

| PL-012-14 / LIZ | 4.00 | 0.49 | 0.037 | 158 | 115 | 172 | 0.27 | ||
| PL-013-14 / LIZ | 2.00 | 2.49 | 0.027 | 143 | 111 | 925 | 0.21 | ||
Channels 10-13 inclusive, with a composite grade of 1.49% Li2O represent a 24 meter section across the LIZ in the northeastern part of the exposed pegmatite.
“With particular focus on the high-grade intercepts, these results not only confirm grade from our maiden resource calculation but will increase the degree of confidence with some of the zone’s tonnage. All other intercept data provide important information as no credit for lithium grades in the maiden resource estimate published (December, 2013) was given”, commented Trevor 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., 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 samples were assayed by AcmeLabs’ (A Bureau Veritas Group Company), an ISO accredited laboratory in Vancouver, British Columbia. Sample blanks along with tantalum, lithium, rubidium and cesium certified reference material were 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 Eq1 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. A 9-hole, 1,500m Phase II diamond drill program was completed in late March 2014 which and has not yet been considered in a resource calculation. As a result of the drill program, the pegmatite now has a 400m strike length with an estimated width varying from 10m to 125m with a sub-vertical orientation. The resource remains open to depth and along strike to the northwest and southeast.

- Assumptions and calculations used for the Li2O Eq included on page 69 of WSP Resource Estimate and Technical Report, January 17, 2014 filed with SEDAR January 20, 2014. A cut-off of 0.4% Li2O was used for all calculations.
