MGX Minerals Intersects Broad
Intervals of Spodumene Pegmatite Mineralization at Case Lake,
Ontario Lithium Project
Vancouver, BC -- September 21, 2017 -- InvestorsHub NewsWire
-- MGX Minerals Inc. (MGX or the Company)
(CSE: XMG / FKT: 1MG / OTC: MGXMF) is pleased to announce
that it has been provided with an update regarding ongoing drilling
at its Case Lake Lithium Joint Venture with Power Metals Corp.
Drilling has successfully intersected significant mineralization
at the Companys Case Lake Lithium Joint Venture. The Case Lake
drill target area consists of a pegmatite dyke swarm: North, Main
and South Dykes as well as multiple unnamed pegmatite dykes. Drill
hole PWM-17-08 intersected 35.22m of continuous spodumene pegmatite
as part of the Main Dyke with very coarse-grained spodumene
crystals up to 10 cm long.
A total of 12 drill holes have been completed to date. With the
exception of hole 3, all drill holes intersected spodumene bearing
pegmatite (Table 1, Figure 7). Assays are pending. The drill
program targeted downdip extension of North, Main and South Dykes
in an area of known mineralization, strike extension and in
previously untested areas such as the South Dyke. Drill core has
been split and shipped with assays now pending.
Highlights include:
Drill holes PWM-17-08, 09 and 10 tested the up and down dip
extension of the Main Dyke.
- PWM-17-08 intersected continuous spodumene pegmatite from 18.86
to 54.08 m for an interval of 35.22 m of the Main Dyke (Figures 1
and 2).
- PWM-17-09 intersected continuous spodumene pegmatite from 26.5
to 60.0 m for an interval of 33.5 m of the Main Dyke. This
intersection included a 42 cm long x 2 cm wide pale green spodumene
blade (Figures 3 to 6).
- PWM-17-10 intersected spodumene pegmatite from 33.83 to 62.05 m
for an interval of 28.22 m of Main Dyke. This interval includes two
sections of Case Batholith host rock: 2.99 m and 0.62 m long.
Drill holes PWM-17-01, 02 and 03 intersected the Main and South
Dykes as part of the western extension of the strike length of both
Dykes.
- These holes extended the Main Dyke Zone lithium mineralization
152 m to the west from historic drilling. These were the first
holes drilled in the previously untested South Dyke and were
designed to test for lithium mineralization at depth.
- Pegmatite dykes were intersected as predicted in the 3D model
of the Project built on historical drill data.
- The Main Dyke Zone in PWM-17-02 was intersected from 53.10 to
88.84 m for an interval of 35.74 m. The Zone consisted of a 10.4 m
long spodumene pegmatite dyke with up to 25 vol% very
coarse-grained spodumene, a 2.99 m long aplite dyke, and multiple
other thin aplite dykes.
Drill holes PWM-17-04 and 05 tested downdip extension of North
and Main Dykes downdip of historic hole DDH-5.
- Drill hole PWM-17-04 intersected 1.7 m of North Dyke. The Main
Dyke Zone was intersected from 75.2 to 107.55 m for an interval of
32.35 m. The Main Dyke Zone consisted of 3 spodumene-bearing dykes
up to 12.8 m long, one pegmatite dyke and one aplite dyke. One dyke
within of the Main Dyke Zone is a 1.85 m long spodumene dyke which
contains 30-40 vol% pale green coarse-grained spodumene. Assays are
pending. (Visual estimates of spodumene vol% do not always equate
to Li2O % grade.)
Drill holes PWM-17-06 and 07 tested the downdip extension of the
Main Dyke downdip from historic hole DDH-2. Drill hole PWM-17-06
intersected 9 m of spodumene pegmatite.
Drill holes PWM-17-11 and 12 tested the eastern extension of the
Main Dyke along strike. These holes intersected multiple pegmatite
dykes hosted by metasedimentary rocks.

Case Lake
Case Lake Property is located in Steele and Case townships, 80
km east of Cochrane, NE Ontario close to the Ontario-Quebec border.
The Case Lake pegmatite swarm consists of five dykes: North, Main,
South, East and Northeast Dykes. Both the North and Main Dykes have
spodumene-rich zones (muscovite-K-feldspar-quartz-spodumene-albite)
and albitic aplite border zones. Spodumene is absent in the
beryl-type South Dyke and the potassic pegmatite East Dyke. The
Northeast Dyke contains very coarse-grained spodumene. MGX
currently maintains a 20% working interest in the project with a
right to acquire up to 35% of the project and an additional 3 other
Ontario Lithium properties controlled by Power Metals.
