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 – December 16, 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 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.
- Channel (CH) PL-021-14 intersected 4.46% Li2O over 8 metre (m);
- CH’s PL-010-14 to PL-013-14 with a composite grade of 1.49% Li2O represent a 24 meter section across the LIZ in the northeastern part of the exposed pegmatite;
- Resource remains open to depth and along strike to the northwest and southeast;
- Resource estimate update commenced December 8, 2014.
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.
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.
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.
