Midland Generates New Exploration Targets ON Several of Its James BAY Projects and Expands Its Portfolio of Lithium Projects
MIDLAND GENERATES NEW EXPLORATION TARGETS ON SEVERAL OF ITS
JAMES BAY PROJECTS AND EXPANDS ITS PORTFOLIO OF LITHIUM PROJECTS
Montreal, March 6, 2023. Midland Exploration Inc. (“Midland” or the “Corporation”) (TSX-
V: MD) is pleased to report that it has completed a regional targeting study for lithium mineralization
in the Eeyou Istchee James Bay region , which is recently highly regarded for its lithium potential and
occurrences. New targets were identified on several currently 100% owned Midland projects that were
deemed highly prospective for lithium potential, and new projects were also acquired on February 28th,
2023, by map designation for their lithium exploration potential.
Highlights
• New strong lithium lake bottom sediment anomaly identified on the Komo project, located
20 km west of the James Bay lithium deposit (Allkem);
• New cluster of strong l ithium lake bottom sediment anomalies identified on t he S hire
project and located along the Lac des Montagnes amphibolites that host the W habouchi
lithium deposit about 60 km further southwest;
• New strong l ithium lake bottom sediment anomaly on the Chisaayuu block (Mythril
Regional project);
• New lithium lake bottom sediment anomalies on the Mythril project;
• New important claim acqui sitions resulting from new targets generated by lake bottom
sediment statistical processing.
The new targets are the result of an extensive statistical processing of more tha n 23,000 lake bottom
sediment analyses which were extracted from the Québec government’s digital SIGÉOM database and
complemented with additional data from local and higher resolution surveys, such as those completed
by Midland . The statistica l processing was orien ted towards identifying the footprint of lithium-
bearing S-type pegmatites and mineralization as well as defining exploration targets. This processing
has proven its ability to positively identif y lake bottom sediment anomalies around recent lithium
discoveries and more advanced projects in Eeyou Istchee James Bay. Other new and similar secondary
environment footprints were also identifie d, thus defining new targets on several active Midland
projects while also generating targets and claim acquisitions.
Midland h as 4,166 claims totalling 2,163 square kilometres of land positions in Eeyou Istchee
James Bay and is among th e top claim holders in t he region . Four Midland projects, namely
Komo, Galinee, Shire and Mythril Regional, were recently identified as high ly prospective for their
lithium potentia l based on striking geological similarities with adjacent lithium d iscoveries and
compelling occurrences of lith ium (Li), tantalum (Ta) and/or beryl lium (B e) in hi storical rock
sampling. Moreover, the statistical study identified new targets on the Komo, Shire, Mythril Regional,
and Mythril projects. It should be noted that none of these projects have specifically been explored for
lithium in the past. Occurrences of Li, Ta and /or Be noted on each of th ese projects were found while
exploring for other commodities.
Komo Project
The Komo project is located about 20 kilometres west of the James Bay lithium deposit (Allkem). It is
located at the contact be tween the La Grande and Nemiscau geological subprovinces, th e same major
geological structure that h osts the James Bay lithium deposit and is lik ely cr itical for its genesis .
Prospecting for gold in 20 22 uncovered a Li-Ta-Be pegmatite outcrop that returned 0.04% Li 2O,
159 ppm Ta, 396 ppm Be in a grab sample. Furthermore, a strong lake bottom sediment anomaly
located along the favourable contact was identified. This target enhances the strong lithium potential
of the Komo project when combine d with the strongly anomalous Li -Ta-Be val ues and the ver y
favourable geological setting.
Shire Project
The Shire project is located within amphibolites of the Lac des Mont agnes geological Group, which
hosts the Whabouchi lithium deposit about 60 kilometres southwest of Shire. The Whabouchi lithium
deposit is characterized by a pegmatite intrusion assigned to the Senay granitic Suite that also intrudes
amphibolites of the La c des Montagnes Group. In 2021, the Qu ébec governmen t ma pped at l east
6 granitic intrusions belonging to the same highly favourable Senay granitic Suite on the Shire project.
None of the favo urable pegmatitic intrusions have been assayed for lithium. The Shire project is also
located at the boundary between the La Grande and Opatica geological subprovinces, a major structure
that could be crit ical for the emp lacement of l ithium-bearing pegmatites in the area. A cluster of
several strong lake bottom sediment lithium anomalies were identified on the project. Historical
exploration work by Midland fo r base metals reported a tourmaline-garnet-bearing pegmatite outcrop
that returned a strong anomaly of 399 ppm Be (grab sample), not assayed for Li, Ta, Cs or Rb. The
new favourable lake bottom targ ets combined with geological characteristics a nd strong hints of
metal-bearing pegmatites on the project suggest an important lithium exploration potential.
Mythril Regional Project
The Mythril Regional project is a larg e project with several extensive claim blocks. The Mythril East
claim block is located 7 kilometres northeast and directly on strike with the Corvette pegmatite field
(held by Patriot Battery Metals). On another claim block , Chisaayuu, compilation of historical work
by Midland revealed strong evidence of Li -Be-Ta pegmatite potential. While exploring for copper in
2022, a pegmatite outcrop returned two strongl y ano malous l ithium values in grab samples : 0.12%
Li2O and 0.04% Li 2O. Furthermore, a new tight cluster of lake bot tom lithium anomalies w as
identified near the cont act between intrusive gr anitic rocks and amphib olites on the project. Grab
samples of peg matitic boulders in other claim blocks in the area also returned highly anomalous Li -
Ta-Sn values: 0.03% Li2O, 23 ppm Ta, 50 ppm Sn; 0.02% Li 2O, 72 ppm Ta. None of these anomalies
have been followed up. All of these further suggest a favo urable exploration potential for lithium on
the Mythril Regional project, which has never been explored for lithium.
Mythril Project
The Mythril project is located a couple of kil ometres northwest and north of the C orvette pegmatites
worked by Patriot Battery Metals. On this p roject, Midland discovered the Mythril copper-gold
mineral system by prospecting in lat e 2018 and concluded a st rategic investment with BHP Canada
Inc. (“BHP”) in the spring of 2019 totall ing $5.85 million for copper exploration in Qu ébec. The
project was recently the subject of an option agreement for critical elements, including lithium, with
Brunswick Ex ploration Inc. New moderate lake bottom lithium anomalies were i dentified on the
project, which has never been explored for lithium yet.
New Claim Acquisitions
The new claim acqui sitions result from new targets generated by the lake bottom sediment statistical
processing, combined with a g eological assessment of the underlying environment for favo urable
lithium potential.
The Picard project consists o f 65 claims located approximately 6 6 kilometres northeast of the
Whabouchi lithium deposit and 9 kilometres north of the Shire project. The project includes a cluster
of several anomalous lake bottom sediment s with anomalies up to > 99.5 th percentile of the ent ire
database. The project is also located over wacke-derived paragneiss and tonalitic rocks containing
muscovite-bearing granitic intrusions nearby, north of a n important structure at the northern edge o f
the Lac des Montagnes Group.
The Warp project consists of 112 contiguous claims located approximately 63 kilometres east of the
Whabouchi lithium deposit. The project includes strongly anomalous lake bottom sediment s with
several anomalies up to > 99.5 th percentile of the entire database. The project is located wit hin the
Opatica Subprovince where pegmatites intruding tonalitic rocks were recently identified by
government mapping in 2021. This area is vastly underexplored.
The Sulu project consists of a t otal of 17 5 claims spread across two blocks, resp ectively located
approximately 40 and 50 kilometres northwest and nort h of the Moblan lithium deposit. Both blocks
are located within portions of the Opatica Subprovince covered only by limited regional-scale
mapping. The general unit coveri ng both blo cks is described as a “granite ho sting pegmatites an d
paragneiss inclusions.” The Sulu SW bloc k (22 claims) covers a strong lake bottom anoma ly with a
calculated value a bove the 99.5 th percentile. The Sul u NE bl ock also contains several lake bottom
anomalies that are in the same p ercentile range. This area is vastly under explored and poorly mapped
but hosts anomalous lithium values in lake bottom sediments.
Midland is currently planning exploration programs on these projects and will provide a more detailed
update of these programs in the coming weeks.
