HLM Electron Microprobe Study Indicates Low Inherent Iron Spodumene in Lithium Zones at the Pakeagama Lake Pegmatite
12 June 2014 - 2:15AM
Business Wire
Houston Lake Mining Inc. (TSX.V: HLM), is a mining
exploration company that is actively exploring for the rare metals
lithium, rubidium, cesium and tantalum by currently advancing its
100% owned and optioned PAK Rare Metals Project in northwestern
Ontario, Canada. Previous work conducted by HLM has outlined the
presence of potentially economic zones of lithium (spodumene)
within its Pakeagama Lake pegmatite.
Today HLM reported that results of an electron microprobe study
of spodumene samples taken from the Pakeagama Lake pegmatite
lithium zones indicate low inherent iron. The study was carried out
by HLM in collaboration with Queen’s University (Steve R. Beyer,
Ph.D.) and consisted of using an electron microprobe to determine
the total iron content of seventeen spodumene samples taken from
the Upper Intermediate (UIZ), and Lower Intermediate (LIZ) Zones of
the pegmatite.
The spodumene from the spodumene-dominant UIZ intersected in
diamond drill holes (DDH) PL13-001 and -005 had the lowest inherent
iron, with averages ranging from 0.04 to 0.05 weight percent (wt.%)
total iron oxide (Fe2O3) based on a detection limit of 0.03 wt.%.
The inherent total iron in the spodumene from DDHs PL13-003 and
-004, were below the 0.03 wt.% Fe2O3 detection limit.
Spodumene in the lithologically heterogeneous Lower Intermediate
Zone (LIZ) contained variable Fe2O3 contents, with averages ranging
from below the 0.03 wt.% Fe2O3 detection limit in DDH PL13-002, to
0.19 wt.% Fe2O3 in DDH PL13-003. The iron content of spodumene
contained within the LIZ increases as the contact with iron-rich
metasedimentary country rocks are approached, but it has been noted
that a concentration below 0.1% wt.% Fe2O3 is maintained to within
about 10 meters of the pegmatite-metasediment contact.
The monetary value of low-iron (Fe) spodumene is greater than
the more common, higher iron spodumene as the former is desired for
high quality technical grade ore or concentrates used in the
manufacture of specialty glass products such as stove tops,
ceramics and heat-proof cookware. Furthermore, a low Fe spodumene
is also well suited to produce a high-yielding chemical-grade
lithium concentrate which is used to produce lithium chemicals
which form the basis for manufacture of, among other applications,
lithium-ion batteries for laptop computers, mobile phones, electric
bicycles and electric/hybrid vehicles.
“This study has resulted in the unique ability of the Pakeagama
Lake pegmatite’s lithium zones to possibly produce a raw lithium
product that would be low in iron (below .1% Fe2O3) without having
to rely upon concentration,” commented Trevor R. Walker, President
of HLM. “This feature, coupled with the high grades of the deposit
give HLM confidence of the 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.”

About the PAK Rare Metals ProjectThe 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 developing 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. An 8-hole, 1,500m Phase II diamond
drill program was completed in late March 2014; assay results for
this program are pending.
About Houston Lake Mining Inc.HLM’s goal is to become a
fully integrated lithium and tantalum producer through the
development of the PAK Rare Metals Project in Ontario, Canada . The
Company's strategy is to take advantage of the global shift towards
electric/hybrid vehicles and high quality consumer electronics by
becoming a raw material supplier of the elements required for the
pursuit of sustainable energy and other applications in high-tech
electronics and metal alloys. Combined, HLM’s Board of Directors
and Management have over 300 years of finance, exploration and
mining experience to help to facilitate the Company’s goal.
HLM has a total of 86,415,695 common shares issued and
outstanding. For additional information on HLM, please visit
