GOLD MINE DEVELOPMENT IN NEVADA

CPAU : TSX-V | COPAF : OTC

OTCQX: COPAF | TSX-V: CPAU

Nevada-focused gold developer with a 100%-owned, past-producing Carlin-type gold system and a path toward near-term production evaluation.

CopAur Minerals Inc. is advancing the Kinsley Mountain Gold Project in Nevada—a high-grade, Carlin-type sedimentary gold deposit with 418,000 oz of indicated resource, 117,000 oz of inferred resource, and more than 20,000 metres of drill resulting currently being included in the geological model. With an experienced mine-building team, a strong exploration pipeline, and a tight capital structure, Copaur offers leveraged exposure to potential resource growth, and a NAV re-rating in one of the world’s top gold jurisdictions.

WHY COPAUR

Tier-1 Nevada Gold in a Known System

Kinsley Mountain is a past-producing Carlin-type sedimentary deposit close to  infrastructure, and a track record of profitable gold production, offering a de-risked platform for near-term revenue generation. growth compared to greenfield exploration. Troy Canyon is potentially a high-grade
mesothermal system, amenable to selective mining, with off-site ore processing.

Significant Resource Base with Expansion Potential

Kinsley hosts an NI 43-101 mineral resource of 418,000 ounces of gold grading 2.63 g/t Au in the Indicated category and a separate 117,000 ounces grading 1.51 g/t Au in the Inferred category. Within the Indicated resource, the high-grade Western Flank Zone contains 302,000 ounces at 6.11 g/t Au. 20,000 metres of drilling completed since 2020 are currently being incorporated into the 2021 geological model, possibly leading to future resource growth.

Near-Term Development Path

Permit applications are in place, and a Preliminary Economic Assessment (PEA) has been initiated to fully evaluate the restarted of the Kinsley Mountain gold mine. This differentiates CopAur from exploration and positions the company for near-term free cash flow.

High-Grade Exploration Torque

The Troy Canyon Gold Project hosts high-grade mesothermal gold and silver mineralization with multiple untested targets offering additional upside in a district-scale setting.

Mine-Building Leadership

CopAur’s leadership team has decades of direct mine development and gold heap-leach experience, including a Canadian Mining Hall of Fame inductee and executives who have built and operated gold mines in North Amercia and overseas. Execution risk will be reduced with the experienced team CopAur has assembled.

KINSLEY MOUNTAIN GOLD PROJECT

Carlin-Type Sedimentary Gold System with Established Resources
and Growth Potential

Located southwest of West Wendover, Nevada, near the Utah border, Kinsley Mountain is a Carlin-type, sediment-hosted gold system in a premier district.

Current Resource Profile*

  • Indicated: 418,000 oz gold @ 2.63 g/t Au
  • Inferred: 117,000 oz gold @ 1.51 g/t Au
  • Includes 302,000 oz @ 6.11 g/t in high-grade zones
  • (*See 2021 NI 43-101 Technical Report for full details.)
  • CPAU-PRESENTATION-OCT2025-1

Historical Production

From 1995–1999, Kinsley Mountain produced approximately 138,000 oz of gold at an average head grade of 1.34 g/t from open-pit operations demonstrating the project’s ability to profitably deliver gold in a real mine setting.
CPAU-PRESENTATION-OCT2025-1

Exploration Upside

Since 2020, more than 20,000 metres of additional drilling have tested extensions of existing zones and new targets, delivering high-grade intercepts such as:

  • 18.3 g/t gold over 23 metres (targeting Western Flank–style mineralization)
  • CPAU-PRESENTATION-OCT2025-1

This 200,000 metres of drill information is not yet incorporated into the geological model, providing tangible upside as modelling updates are completed.

Geophysics & Targeting

Over 80 line-km of IP/resistivity surveying have defined eight high-priority drill targets across a 20 km² underexplored area north of the known Kinsley deposit. These targets coincide with strong chargeability and resistivity anomalies and represent potential new discovery zones.
CPAU-PRESENTATION-OCT2025-1

Metallurgy

Historical metallurgical work at Kinsley indicates the potential for high recoveries via conventional processing and leach techniques, consistent with other Carlin-type deposits in Nevada.

TROY CANYON GOLD PROJECT

High-Grade Mesothermal Gold-Silver System With Exploration Upside

Troy Canyon is 150 km east of Tonopah and consists of 59 contiguous unpatented mineral claims covering 493 hectares. High-grade gold and silver mineralization occurs within massive quartz veins, vein breccias and narrower sheeted vein and stockwork zones exposed for over 300 meters along the contact between the limestone hanging wall and the quartz monzonite footwall of the Tertiary (23 Ma) Troy pluton.

Key Features

  • Vein system exposed at surface over a 300 m strike length
  • Historic small-scale mining at the Locke mine (1948–1950) produced 643 oz of gold and 660 oz of silver at head grades reported up to 11.8 g/t Au and 12 g/t Ag
  • Underground chip samples from previous operators reported up to 37 g/t Au and 50+ g/t Ag
  • Soil geochemistry indicates several anomalous gold zones beyond historic workings
  • CPAU-PRESENTATION-OCT2025-1

Troy Canyon offers investors additional discovery potential and high-grade torque alongside Copaur’s flagship Kinsley Mountain asset.

NEVADA & GOLD MARKET BACKDROP

Premier Mining Jurisdiction

Nevada consistently ranks as one of the top global jurisdictions for mining investment, offering stable regulations, robust infrastructure, skilled labour, and a long history of gold production. For institutional investors, this reduces permitting and jurisdictional risk compared to many emerging markets.

Gold Market Tailwinds

  • Persistent macro uncertainty, inflation risk, and de-dollarization are driving central bank gold buying and long-term support for gold prices
  • Years of underinvestment in exploration and development have constrained new supply, particularly in Tier-1 jurisdictions like Nevada.

CopAur’s Positioning:

In this environment, Carlin-type deposits in Nevada with established resources and growth potential, like Kinsley Mountain, are becoming increasingly strategic to producers and investors seeking de-risked gold and silver production in safe jurisdictions.

CAPITAL STRUCTURE & SCARCITY

Share Structure*

  • Shares Outstanding: 120,509,609
  • Warrants: 29,374,600
  • Capital base tightly held by management and close associates, aligning insider incentives with shareholders.
  • CPAU-PRESENTATION-OCT2025-1

With under 121M shares outstanding and significant insider ownership, CopAur maintains a relatively tight float, allowing strong leverage to positive exploration and development news.
