Slide 4: Scossa Gold Project – NW Nevada
SCOSSA GOLD PROJECT – NW NEVADA 4 SCOSSA KINKAID • The Scossa claims cover a former high-grade gold producer from the 1930s and early ’40s. ORETERRA METALS CORP. • Occurs at the intersection of two major gold belts, the Sleeper Trend & the Sulfur-Lovelock-Austin Trend / Rye Patch Trend TSX-V: OTMC O
Slide 5: Scossa Gold Project General Geology
SCOSSA GOLD PROJECT 5 GENERAL GEOLOGY • The claims are underlain mainly by Miocene Rhyolite & Shallow Intrusions argillite, phyllite, siltstone and arenites of the Upper Triassic to Lower Jurassic Auld Lang Syne Alluvium Formation. • Strike ~N-S and dip steeply west predominantly. Scossa Auld Lang S
Slide 6: Scossa Land Package
SCOSSA LAND PACKAGE 6 ➢ The Scossa Project land package consists of: • 42 mining claims on Section 30 10 • 8 mining claims on Section 30 14 • 66 acres of private land on Section 30 15 purchased from the C-Punch Ranch. ➢ The property covers a combined 865 acres or 349 hectares. ➢ The surrounding priv
Slide 7: Scossa Gold Project
SCOSSA GOLD PROJECT 7 • Past production from 5 epithermal veins in faults up to 6 ft. wide. • Ore was so rich it was stored in the bank vault in Lovelock. • Mining was limited to the upper 400 ft. • Geology of similar deposits nearby suggest there should be 1,000 ft. of potential ore left beneath ol
Slide 8: Scossa Gold Project
SCOSSA GOLD PROJECT 8 • Romios’ conducted 3 drilling programs in 2000, 2003 & 2006. 14 diamond drill holes in 2000, hampered by West poor recoveries due to small core size. 16 RC holes in 2003 & 2006 (no core, only chips). Angel Scossa • DDHs returned assays up to: Wing Noble 1-12 North • 3.35 m @ 1
Slide 9: Scossa Gold Project
SCOSSA GOLD PROJECT 9 Epithermal gold-silver veins are vertically zoned upwards from base metals to high-grade Au-Ag to low grades at the top of the system. Gold and silver precipitate from the fluid as it rises to shallow enough levels to allow boiling. Gold and silver start to precipitate at the b
Slide 10: Scossa Gold Project
SCOSSA GOLD PROJECT 10 The boiling zone in epithermal veins produces distinct textures in the vein minerals. Most common is bladed, tabular crystals of calcite that often become replaced by silica. A boxwork of these bladed silica pseudomorphs after calcite occurs at surface on the Angel Wing Vein T
Slide 11: Scossa Gold Project
SCOSSA GOLD PROJECT 11 Boiling zone textures occur at surface on the Angel Wing Vein, near the bottom of Scossa hill. The Angel Wing is one of the lowest veins on the property. Gold and silver should increase upwards from here. Potential for >150m vertical extent of mineralization above the base of
Slide 12: Scossa Gold Project
SCOSSA GOLD PROJECT 12 Recent sampling along all exposed veins, dumps, pits, etc. to help define potential shoots. Assays up to 23 g/t Au, combined with old maps of the mined out stopes, help predict shoot location. Vein textures at surface on the upper veins are mainly quartz cemented breccias. Gol

Slide 17: Scossa Gold Project
SCOSSA GOLD PROJECT 17 • Veins like this can be incredibly high grade. • The Sleeper Mine produced 500,000 oz of gold from a vein one foot wide, 140 ft long and 70 ft high. • Scossa’s high-grade ore was so rich that it was stored in a bank vault in Lovelock. High-grade colloidal Au-Ag Ore From Sleep

Slide 19: Scossa Gold Project – Cinnabar Prospect, SE Corner of the Property
SCOSSA GOLD PROJECT – CINNABAR PROSPECT, SE CORNER OF THE PROPERTY 19 Enormous trench ~60m long and a small historic shaft. Remains of several old cabins, probably 1950s? Appears to follow a highly altered NE-trending fault zone. Relatively undeformed quartzite and shale to the left, becomes highly

Slide 21: Scossa Gold Project – Cinnabar Prospect
SCOSSA GOLD PROJECT – CINNABAR PROSPECT 21 • Chip sampling of the fault along the trench wall returned low gold (<0.7 g/t Au) and silver values. • But high mercury values up to 3.1% • Elevated arsenic up to 833 ppm. • This prospect could well be the uppermost levels of an epithermal vein system, abo
Slide 22: Proposed Work, Spring 2026
SCOSSA GOLD PROJECT 22 PROPOSED WORK, SPRING 2026 • Mapping, prospecting and soil sampling between new discovery and main veins. POTENTIAL WORK, FALL 2026 – Early 2027 • Drill the shallow holes proposed by Rangefront to test the modelled high- grade ore-shoot. • Drill a fence of holes across the vei
Slide 23: Scossa and Kinkaid Projects, Nevada
SCOSSA AND KINKAID PROJECTS, NEVADA 23 Both projects have historic mine workings that were shut down during WWII. Using modern ore deposit models and exploration techniques we expect to find ore zones left behind. Both properties have significant showings that have not been tested for their true pot
