HLM Drills beneath the PAK Inferred Resource Intersecting 1.16% Lithium Oxide over 202 Metres in Ontario, Canada
- Diamond Drill Hole (DDH) PL-013-14 intersected 1.16% Li2O over 202 metre (m) from 15m to 217.45 m;
- DDH PL-013-14 includes a 18 m wide high-grade lithium zones (Upper Intermediate [UIZ] and Lower Intermediate [LIZ]) averaging 3.10% Li2O from 164 to 182 m;
- DDH PL-013-14 was drilled below DDH PL-001-13 (see press Aug. 1, 2013) and confirms the deposit to a depth of approximately 220m from surface;
- Resource remains open to depth and along strike to the northwest and southeast; and
- Assay results pending from 5 remaining drill holes from the Phase II Diamond Drill Program.
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 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.

(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.
