Midland and Altius Resume Exploration Work on Their James Bay Gold and Base Metals Projects

Midland and Altius Resume Exploration Work on Their James Bay Gold and

Base Metals Projects

MONTREAL, May 31, 2018 -- Midland Exploration inc. (“Midland“) (TSX-V:MD) and Altius Minerals Corporation (“Altius”)

(TSX:ALS) are pleased to announce that summer 2018 exploration work will resume on their jointly held (50/50) James Bay

exploration projects, namely Shire (zinc), Moria (nickel-copper-cobalt), Isengard (gold) and Gondor (gold) projects. Exploration

will consist of mechanical trenching of high-grade showings and geophysical anomalies identified in 2017 on Shire and Moria,

soil sampling, as well as prospecting and geological mapping on all four projects.

The Shire Zinc project is located in an underexplored area about 80 kilometers east of Nemaska, Eeyou Istchee, Quebec. The

project was initiated following the discovery in July 2017 of a high-grade zinc showing (O’Connor showing) inferred to be an

exhalative horizon from a volcanogenic massive sulfides (“VMS”) system, which returned up to 7.53% Zn in grab sampling

(note that grab samples are selective by nature and values reported may not be representative ). Channel sampling at

O’Connor in October 2017 yielded up to 4.85% Zn over 1.17 meters in massive sulfide and quartz-rich exhalite ( note that all

thicknesses reported in this press release are apparent thicknesses; true thicknesses cannot be determined at this time ). 

The zinc-bearing sulfide zone is still open to the north and east, under thicker overburden. A mechanical trenching campaign

will be performed in summer 2018 to test possible surface extensions of the mineralized zone undercover at O’Connor.

A heliborne electromagnetic (VTEM) survey flown in October 2017 at Shire demonstrates that the O’Connor showing is located

on a regional-scale conductive unit that is at least 15 km long and is open to the east. Field follow-up of select VTEM

anomalies in October 2017 identified massive pyrite-pyrrhotite and stratabound quartz-pyrite-pyrrhotite at other locations along

the regional EM conductor, 2.5 kilometers and 4.5 kilometers east of the O’Connor showing, respectively. These results

confirmed the presence a major regional mineralized horizon on the project. The sulfide occurrences were all covered by

overburden and discovered by manual trenching of metal detector (beep mat) anomalies. In the summer 2018 campaign,

systematic soil sampling will be performed over the conductive target unit. Soils will be analyzed in real time by portable XRF.

The best combined VTEM and soil geochemical anomalies will then be immediately followed up by mechanical trenching.

Additional prospecting and geological mapping will also be done on the remainder of the largely unexplored greenstone belt to

the east.

The Moria Nickel-Copper-Cobalt project is located about 12 kilometers southeast of the Clearwater Au deposit and 25

kilometers east of Hydro-Quebec’s Eastmain-1 dam. The project was initiated in August 2017 with the discovery of the Gimli

showing that returned up to 1.13% Ni, 0.11% Cu and 0.07% Co in grab samples and 0.80% Ni, 0.06% Co and 0.075% Cu

over 0.8 meter in channel. The mineralized zone found in channels at Gimli is open to the north under thicker overburden. The

Gloin showing, located 100 meters east of Gimli, also returned up to 0.78% Ni in grab sampling. Assay results indicate a

perfect nickel-sulfur correlation, which suggests that most of the nickel is found in sulfides and not in refractory silicates. This

was confirmed with petrographic observations which show abundant pentlandite. Calculated nickel tenors (grades normalized

to 100% sulfides) at Gimli and Gloin are around 14% Ni. The 2018 campaign on Moria will focus on mechanical trenching to

extend the mineralized zones at Gimli and to explore the 100-meter-wide gap between the Gimli and Gloin showings

The heliborne VTEM survey performed in October 2017 on Moria indicates that the Gimli and Gloin showings are located on a

distinct NE-SW trending magnetic anomaly which is about 3.5 kilometers long and coincides with a magnetic meta-pyroxenite

dyke that hosts the mineralization. Select VTEM anomalies located close to the dyke will be trenched. A second meta-

pyroxenite dyke identified on the VTEM survey was also later confirmed by fieldwork, and VTEM anomalies associated with it

will also be investigated by trenching.

Midland and Altius will also initiate their first exploration campaign on their Isengard and Gondor gold projects, located in

eastern James Bay. These projects cover poorly explored segments of the boundary between the La Grande and Opinaca

geological subprovinces which control the location of the most significant gold deposits in James Bay, including the Roberto

deposit (Eleonore mine). Each of these projects also exhibit strong gold or pathfinder geochemical anomalies in rocks, lake

sediments and/or tills which remain unexplained and point to significant gold potential.

Quality Control

Rock samples on the project are assayed by standard 30 gram fire-assaying with AA or gravimetric finish at ALS Minerals

laboratories in Val d’Or, Québec or Sudbury, Ontario. All samples are also analysed for multi-elements, using four-acid ICP–

AES method. Samples that exceed 1% zinc or nickel are reanalyzed by four-acid ICP-AES optimized for high grades.

Exploration program design and interpretation of results is performed by qualified persons employing a Quality

Assurance/Quality Control program consistent with industry best practices, including the use of standards and blanks with

every 20 samples.

James Bay and Northern Quebec at Midland, a “qualified person” as defined by NI 43-101.

About Midland

Midland targets the excellent mineral potential of Quebec to make the discovery of new world-class deposits of gold, platinum

group elements and base metals. Midland is proud to count on reputable partners such as Agnico Eagle Mines Limited,

IAMGOLD Corporation, Osisko Mining Inc., Altius Minerals Corp., SOQUEM INC., NioBay Metals Inc. and Abcourt Mines Inc.

Midland prefers to work in partnership and intends to quickly conclude additional agreements in regard to newly acquired

properties. Management is currently reviewing other opportunities and projects to build up the Company portfolio and generate

shareholder value.

About Altius

Altius directly and indirectly holds diversified royalties and streams that generate revenue from 15 operating mines. These are

located in Canada and Brazil and produce copper, zinc, nickel, cobalt, iron ore, potash and thermal (electrical) and

metallurgical coal. The portfolio also includes numerous pre ‐development stage royalties covering a wide spectrum of mineral

commodities and jurisdictions. It also holds a large portfolio of exploration stage projects which it has generated for deal

making with industry partners that results in newly created royalties and equity and minority interests.
