Midland and Altius Discover New Gold Showings in the James Bay Area

MONTREAL, QUEBEC--(Marketwired - Oct. 12, 2017) - Midland Exploration inc. ("Midland") (TSX VENTURE:MD) is pleased to announce the discovery of several new gold showings, as part of its strategic exploration alliance with Altius Minerals Corporation ("Altius") (TSX:ALS). These new gold showings were found on targets that were identified during the target generation phase of winter-spring 2017.

On the Elrond project, located about 80 kilometers south of Radisson, Quebec, grab samples from an amphibolite strongly mineralized in arsenopyrite and pyrite yielded values of 4.52 g/t Au and 3.23 g/t Au, (note that grab samples are selective by nature and values reported may not be representative). About 100 meters to the north, a grab sample of silicified amphibolite yielded 1.81 g/t Au. Overall, 10 grab samples out of 59 collected from the Elrond project returned gold values over 0.1 g/t Au. Three of these Au-anomalous samples are late pegmatitic dykes that have a Au ?Mo ?Bi ?As signature (up to 0.89 g/t Au, 268 ppm Bi, and 628 ppm Mo). The presence of Au-Bi-Mo bearing, late pegmatitic/granitic dykes, suggests that the area has a potential for Alaska-type intrusion-related gold deposits. The Elrond project is located directly at the prolific contact between the La Grande and Opinaca geological subprovinces, which hosts many important gold deposits and showings in the James Bay region (such as Eleonore, La Grande Sud, Cheechoo, Corvet-Est, Orf?(C)e and La Pointe). There is no previous exploration recorded on the project.

The Minas Tirith project is located directly on the James Bay road, about 90 kilometers south-east of Eastmain, Quebec. It is located very close to the Pontax regional shear zone that forms the boundary between the La Grande and Opinaca subprovinces in the area. The project was staked based on historical anomalous gold values in grab samples reported from a previous exploration campaign. A grab sample from wacke displaying Eleonore-type calc-silicate alteration and injected with quartz veins returned 5.23 g/t Au. Four (4) grab samples out of 16 collected from Minas Tirith returned anomalous gold values over 0.1 g/t Au. This is the first known significant gold showing (> 1g/t Au) in the area, the closest one being more than 40 kilometers away to the north-east.

The new Helm's Deep project is located on the shore of the Eastmain-1 reservoir, about 20 kilometers south-east of the Clearwater gold deposit. The project was staked following the discovery of a new gold showing that yielded 2.42 g/t Au in a grab sample, in a strongly sheared sandstone with trace pyrite. Grab sampling of quartz-tourmaline-biotite veins within sandstones also returned anomalous gold values of 0.72 g/t Au and 0.68 g/t Au. Four (4) grab samples out of a total of 39 collected in the western part of the project returned more than 0.1 g/t Au. Gold mineralization is hosted in sandstones and polymictic conglomerates that exhibit widespread calc-silicate alteration peripheral to zones of biotite-tourmaline alteration. The alteration and host rocks at Helm's Deep are reminiscent of the Eleonore gold deposit. There is no previous exploration recorded on the project.

Midland and Altius are very pleased by the results of this first phase of prospect generation work. These gold showings as well as nickel ("Gimli" showing, Moria project) and zinc ("O'Connor" showing, Shire project) showings were all found during just four weeks of reconnaissance in July 2017. An electromagnetic airborne survey will be performed in the next few weeks on both the Shire and Moria projects (combined total of 755 kilometers of survey lines) to identify new massive sulfide drill targets. An additional prospecting campaign is also planned for the Shire, Moria and Helm's Deep projects in October to expand on these new showings.

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, Qu?(C)bec or Sudbury, Ontario. All samples are also analysed for multi-elements, using four-acid ICP-AES method. 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.
