Hlm Extends Eastern Extension On The Pak Lithium Project Intersecting 2.59% Li2O Over 40 Metres
Sudbury, Ontario – December 15, 2015- Houston Lake Mining Inc. (TSX.V: HLM), HLM is pleased to announce the results the Phase IV drill program of two (2) drill holes targeting the Pakeagama Lake pegmatite. The objectives of the program were to test the orientation of the eastern extension of the pegmatite by intersecting the pegmatite at a predicted depth with a vertical hole and then to step back and intersect the pegmatite with an angle hole in order to substantiate the hypothesized southeasterly plunge of the deposit. The program was a success, firstly, by intersecting the pegmatite body with the vertical hole at the predictive depth of 155m below surface subsequently stopping the hole while still in mineralization after intersecting 95.45m of the PAK pegmatite. The program, secondly, transected 40m of pegmatite with the step-back follow-up hole despite the hole deviating away from its planned target. The assay and collar data for the 2 holes reported are presented in Tables I and II, respectively. The intersection summaries including the two drill holes general location and purpose are outlined in Table I below. The table also summarizes the lithium, cesium, tantalum and rubidium grades for the two drill holes by mineralogical zones for the pegmatite intersections.
Vertical Diamond Drill Hole (DDH) PL-023-15 was terminated after intersecting 95.45 m of 1.98% Li2O 155 m below surface verifying the pegmatite body is plunging to the east-south-east;
DDH PL-024-15 intersected 40m of pegmatite averaging 2.59% Li2O from 264m to 304m;
DDH PL-024-15 includes a lithium zone (Upper Intermediate Zone) averaging 3.65% Li2O over 9.1 m from 265.9 to 375.0m and;
Mineralization remains open to depth and along strike to the northwest and appears to be opening up to the east-south-east.
Table I – Core Length Intercepts (Pakeagama Lake 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.

The Upper Intermediate (UIZ), Central Intermediate (CIZ), Lower Intermediate Zones (LIZ) and Wall Zone (WZ) 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. The success of the Phase IV indicates the pegmatite may be increasing in grade-thickness and consistency (no apparent dilutive granitic or medasediment blocks or rafts) to the ESE.
“We are extremely pleased with these results from the Phase IV diamond drill program as they prove the pegmatite is plunging to the ESE”, commented Trevor R. Walker, President of HLM. “The program is a positive test of our plunge theory, resulting in increased predictability for intersecting the deposit. This predictability, along with the high grade thicknesses intersected to date, and mineralization that remains open to depth and along strike, suggests this pegmatite could be significantly more robust than is currently known.”

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. Drill hole PL-023-15 was drilled vertically to determine the depth and plunge of the pegmatite. Drill hole PL-024-15 was 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. Core marked for splitting was cut using a diamond core saw on site and 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 replaced in the core box. All core remains securely in a locked sea-container on site.
All samples were assayed by AGAT Laboratories Ltd. (“AGAT”), an ISO accredited laboratory in Rosslyn, Ontario. 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 Frontier Lithium Inc. HLM’s goal is to become a fully integrated lithium, rubidium and tantalum producer with development of the PAK Lithium Project in Ontario, Canada. Based on the PAK deposit’s high-purity, technical-grade spodumene, a relatively lower capital requirement to enter in to the lithium supply market is possible by firstly becoming a technical-grade lithium concentrate supplier. HLM is focused on a staged approach to indirectly participate in the burgeoning lithium battery industry by taking advantage of the disruptive change to market fundamentals by targeting the ceramic-glass industry (industrial users). Currently, the glass/ceramics segment is the second largest in total lithium demand whereby supply pressure is taking place due to the threat of lithium battery growth.
