HLM Drills Eastern Extension On The Pak Lithium Project Intersecting 2.64% Li2o Over 70.4 Metres

• PDF

Sudbury, Ontario -September 8, 2015- Houston Lake Mining Inc. (TSX.V: HLM) - HLM is pleased to announce the remaining results of three (3) drill holes from a Phase III Diamond drill program designed to define the upper extent of mineralization along the eastern extension between holes PL-13-001 and PL-010-14. The assay and collar data for the 3 holes reported are presented in Tables I and II, respectively. A fouth hole, PL-022-15, drilled 100m to the east did not interesect pegmatite, however, the presence of tourmaline-rich aplite and quartz veins suggest proximity to the pegmatite body.

Highlights:

• Diamond Drill Hole (DDH) PL-016-15 intersected 2.64% Li2O over 70.4 metre (m) from 77.45m to 147.85m including an Upper Intermediate Zone (UIZ) of 3.68% Li2O over 15.45m from 96.0 to 111.45m,
• DDH PL-019-15 scissored from the south and 30m to the east of PL-016-15, intersected 2.25% Li2O over 70.55m from 103.15 to 173.70m including an 11.0m wide lithium-enriched zone averaging 3.03% Li2O from 123.0 to 134.0m,
• Mineralization remains open to depth and along strike to the northwest and southeast.
• Drill results suggest mineralization is plunging to the south-east and possibly present beneath hole PL-022-15 (100m east of known mineralization).
  
  

(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.
(3) There is insufficient data to determine if the noted intersection is a part of the Pakeagama pegmatite. Due to the intercept's spatial location it is unknown if the mineralization indicates another pegmatite at this time.
n/a = Not applicable

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 scissor pairs of DDH-16 and 19 and DDH-10 and 17 indicate that the pegmatite zone is at minimum 40m wide, sub-vertical and appears to be plunging under the granite blocks intersected in the shallower holes.

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 Activation Laboratories Ltd. ("Actlabs"), an ISO accredited laboratory in Ancaster, 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 the PAK Lithium Project
The PAK Lithium 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) type pegmatite. These types of pegmatites have been the principal source of hard rock lithium, tantalum, rubidium and cesium ores mined in the world but there are comparatively few commercially-viable deposits.

HLM is actively exploring its 100% owned and optioned project which contains the Pakeagama Lake pegmatite. The deposit is one of the highest grade lithium deposits in North America which has a current Indicated Resource of 2.45 million tonnes of 1.81% Li2O Eq.

and Inferred Resource of 5.91 million tonnes of 2.01% Li2O Eq. which has a technical/ceramic grade spodumene with low inherent iron (below 0.1% Fe2O3) . The deposit has adjacent zones that are enriched in rubidium and tantalum. HLM is also evaluating the phased co-production of rubidium and tantalum concentrates once lithium mineral production has been commercialized.

The deposit has a known 400m strike length with an estimated true 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. The Phase III, 1,500m Diamond drill program was conducted with the objective to upgrade the lithium Indicated mineral resource to a Measured category, and to possibly upgrade the Inferred mineral resource to a Measured and Indicated category.
