Key Concepts

• Osisko Development: Gold production, underground infill drilling, and site remediation.
• Gold Mining Inc.: Exploration drilling, geophysical surveys, and mineral system expansion.
• Premier American Uranium: Heap leach recovery optimization, Preliminary Economic Assessment (PEA) sensitivity analysis, and metallurgical testing.
• Technical Terms:
  • Infill Drilling: Drilling between existing holes to increase confidence in resource estimation.
  • IP Survey (Induced Polarization): A geophysical imaging technique used to identify subsurface mineral deposits.
  • Heap Leach: An industrial mining process to extract precious metals from ore using a series of chemical reactions.
  • NPV (Net Present Value): The value of all future cash flows (positive and negative) over the entire life of an investment, discounted to the present.

1. Osisko Development (ODV)

Financial and Operational Performance:

• Liquidity: Ended 2025 with approximately $422.3 million in cash and cash equivalents.
• Revenue: Q4 2025 gold sales reached 3,970 ounces ($24.2 million); full-year 2025 sales totaled 6,240 ounces ($35.5 million).
• Financing: Strengthened the balance sheet via an $82.5 million private placement, a $144 million prospectors offering, and $24.99 million from warrant exercises.

Caribou Gold Project Updates:

• Drilling: The 13,000-meter underground infill program in the Lowh zone is 96% complete, with results released for 80% of the program. Completion is slated for Q2 2026.
• Infrastructure: The Bonanza Ledge water treatment plant is expected to be fully operational by Q2 2026.
• Safety/Reopening: Following a temporary suspension due to a fatal accident in January 2022, the site has resumed activities under a staged reopening plan.
• Outlook: 160,000 meters of drilling are planned for 2026 to derisk the project while exploring upside potential.

2. Gold Mining Inc.

Exploration Strategy at São Jorge (Brazil):

• Drill Program: An 8,000-meter, fully funded program is underway using two rigs to target high-priority zones identified in 2025.
• Geophysics: A 49-line kilometer IP survey is being conducted east of the deposit to expand the geological database.
• Key Target (William South): Located within 2 km of the main deposit. Historical highlights include 12 meters grading 2.38 g/t gold from 13 meters, including a 1-meter interval at 22 g/t gold.
• Mineral System: The company has identified a 12x7 km area of elevated surface geochemical anomalies, suggesting a large-scale mineralized system.
• Infrastructure: The site benefits from grid power, highway access, and a 50-person camp.

3. Premier American Uranium (PUR)

Chibuleta Project (New Mexico) 2026 Work Program:

• Budget: $1.1 million USD.
• Objective: Optimize assumptions from the 2025 PEA, specifically focusing on improving uranium recovery rates via heap leaching.
• Methodology:
  1. Bulk Sampling: Collected in March and sent to Hazen Research.
  2. Drilling: Up to 60 new holes starting in late April, concluding in June 2026.
  3. Metallurgical Testing: A 42-week lab campaign beginning in May 2026.
• Economic Impact: The 2025 PEA used an 80% recovery assumption. Sensitivity analysis indicates that increasing recovery to 90% could boost the after-tax NPV (at an 8% discount rate) by approximately 90%—from $84 million to $159 million USD.
• Timeline: Results will inform an updated PEA expected in Q1 or Q2 2027.

Synthesis and Conclusion

The mining sector updates presented highlight a transition toward operational maturity and resource expansion. Osisko Development is focused on stabilizing production and derisking the Caribou project through significant capital infusion and infrastructure completion. Gold Mining Inc. is leveraging existing infrastructure to aggressively test high-grade targets, aiming for resource growth. Premier American Uranium is employing a high-leverage strategy, where a relatively small investment in metallurgical optimization could nearly double the project's economic value. Collectively, these companies are entering 2026 with funded programs and clear technical milestones aimed at enhancing shareholder value.
