Forward‐looking statements may relate to future outlook and anticipated events or results. By their very nature, forward‐looking statements involve numerous assumptions, inherent risks and uncertainties, both general and specific, and the risk that predictions and other forward‐looking statements will not prove to be accurate.

Qualified Person’s Statement Roderick Smith, M.Sc., P.Geo., Chief Geologist for Altius, is the Qualified Person as defined by National Instrument 43-101, Standards of Disclosure for Mineral Projects. Mr. Smith is responsible for the scientific and technical data presented herein and has reviewed and approved this project summary. Of note, historical results reported herein have not been verified by Altius personnel. Surface grab samples are selective by nature and are unlikely to represent average grades of the mineralization found on the property. 2
SUMMARY OBSERVATIONS The Seal Lake Group is clearly prospective for large sediment-hosted stratiform copper deposits but is underexplored • Located in a Mesoproterozoic (1270-1225 Ma) supracrustal sequence with well documented SSC-type copper occurrences. • Mineralization is structurally controlled yet generally stratiform. • Reduced grey beds host the most significant copper occurrences. District-scale comprehensive evaluation has not been conducted since 1970’s • Previous exploration programs lacked sustained effort or suffered from poor targeting techniques. • Historical drilling characterized by very shallow, closely spaced drill holes. Altius has identified and acquired four target areas • Recent evaluation suggests an overlooked opportunity. • Prospective copper-bearing horizons have not been adequately tested. • Altius is the sole owner of mineral rights in the area.

LABRADOR MINING DISTRICTS The Adeline Copper project is located within the Central Mineral Belt (CMB) in the province of Newfoundland Labrador, Canada – 145 km NW of the community of Happy Valley-Goose Bay, Labrador. A hydro access road is within 70 km of the project. The province is politically stable with a transparent permitting process, established mining and taxation laws, and with mining-knowledgeable First Nations groups. ADELINE COPPER PROJECT World-class, large-scale mining operations located in northern Labrador at Vale’s Voisey’s Bay Ni-Cu-Co mine and western Labrador at Rio Tinto’s Carol Lake Fe mine - supported by a network of roads, rail, deep water ports, airports, service centers, hydroelectric power, and a skilled workforce. 4
CENTRAL MINERAL BELT OF LABRADOR • The Central Mineral Belt (CMB) consists of six successive Proterozoic supracrustal sequences and associated Archean basement rocks that occupy an area of 260 by 75 km in central Labrador. - Aillik Group - Post Hill Group - Moran Lake group - Bruce River Group - Letitia Lake Group - Seal Lake Group • Records multiple magmatic and hydrothermal Cu events between ca. 1800 Ma and 1330 Ma. U • The Seal Lake Group is the youngest supracrustal sequence in the CMB and hosts the majority of the copper occurrences known throughout the belt. Van Nostrand & MacFarlane, 2011 5
CENTRAL MINERAL BELT OF LABRADOR • The CMB is a globally significant Cu-U province. • 260 km long belt endowed with hundreds of copper, uranium, silver, REE and molybdenum showings. • Intense uranium exploration in east a decade ago but the west was ignored because no uranium occurrences were known. • The western part of the CMB is dominated by copper occurrences hosted within the Seal Lake Group.

REGIONAL TECTONIC ELEMENTS Orogenic activity and continental re-aggregation between 1.3 and 1.0 Ga (Grenville Orogeny) formed copper deposits White Pine / Katanga associated with sedimentation and basaltic volcanism in intra- Keweenawan continental rifts. Seal Lake Rodinia 1070 Ma 7
REGIONAL TECTONIC ELEMENTS Deposition, volcanism and intrusion in the Seal Lake Group were broadly coeval with the Laurentia-wide rifting, such as that exhibited by the Mid-continental Rift System (MRS) of North America. Seal Lake Otish Basin MRS White Pine / Keweenawan 8
REGIONAL TECTONIC ELEMENTS Seal Lake Group - Geology • ~10,000 km2 in central Labrador (outlined in blue) • Mesoproterozoic supracrustal sequence • Argillite, arenite • Basalt flows • Gabbro sills • Triple junction of the Churchill, Nain and Grenville provinces • The Seal Lake Group formed as a result of extensive continental sedimentation during a rift related cycle of uplift and erosion. 9
LAND TENURE Altius Map Staked Claims • Altius is the sole tenement holder covering prospective stratigraphy • 12,925 Ha (129.3 km2) in five contiguous map-staked mineral licenses (517 claims; all first year) • CDN $103,400 in exploration expenditures required in 2021 • One aboriginal group with a formal land claim • No parks, ecological reserves or restricted land use areas 10
REGIONAL COPPER MINERALIZATION 250 copper occurrences 120 km long – 45 km wide • Hosted primarily by the middle formations of the Mesoproterozoic Seal Lake Group • Copper mineralization is structurally controlled, epigenetic and likely associated with the Grenville Orogeny (ca. 1.0 Ga.) Chalcocite mineralization in grey beds at Adeline Island Copper occurs in two settings: 1. Chalcocite and/or bornite stringers and quartz-carbonate veins in diabase, basalt, or grey to black shales, arenite and phyllite (reduced “grey beds”) Primary Target 2. Native copper-bearing quartz-carbonate veins within red slate and/or strongly hematitic basalt units. Native copper mineralization in basalt at Salmon Lake Main 11

STRUCTURAL MODEL • The Seal Lake Group is complexly folded into an east-trending, doubly plunging syncline • The southern limb of the syncline has been overturned and thrust northward during Grenvillian deformation (ca. 1.0 Ga) • Deformation has created ‘structural traps’ that host copper mineralization The claim outline denoted in blue is outdated and the reader should refer to slide 10 (“Land Tenure”) for the current property outline. 14
STRUCTURAL MODEL Copper mineralization is epigenetic, likely attributed to deformation associated with the Grenville Orogeny. The mineralization occurs as veins and replacements along contact zones and deformation zones associated with folds and faults. Evident at all scales.
