HLM’s Phase II Drilling Confirms And Extends High-Grade Lithium Zone At Surface On The Pak Rare Metals Project, Ontario

Sudbury, Ontario – September 2, 2014 – 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 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.


  • 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.

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 (0.1% 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 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.
