Selena Project: New Discovery and Market Misunderstanding

Ridgeline Minerals, led by President and CEO Chad Peters, announced a significant new discovery at their Selena project, a CRD-style deposit. This discovery, located at depth, targets deep carbonate replacement mineralization of silver, lead, zinc, and copper. The announcement, however, did not receive the expected positive market response, which Peters attributes to a difficulty in communicating the polymetallic nature and value of the mineralization.

Key Points of the Discovery:

• Target: The maiden drill program focused on a 2 km long by 1.5 km wide target identified by geophysical surveys in 2024.
• Second Hole (SC25-053): This hole intersected multiple massive sulfide horizons with highlight intercepts, including:
  • Up to 1 meter of 27% zinc, 60 g/t silver, 1.5 g/t gold, and 1.5% copper.
  • Up to 17 meters of 6% zinc with 30-40 g/t silver, 0.1 g/t gold, 0.1% antimony, and 0.1% copper.
• Validation of Target: The discovery validates Ridgeline's three-year assertion that the Chinchilla sulfide target at Selena is analogous to the Taylor deposit, a major silver-lead-zinc deposit owned by their partner, South 32.
• High-Grade Intercepts: The grades reported are exceptionally high, demonstrating significant upside potential.
• Polymetallic System: The mineralization is described as a "total trash can" of polymetallic elements, indicating a complex and potentially very valuable system.

Addressing Market Misunderstanding:

Peters acknowledges that the market struggled to grasp the value of a polymetallic deposit where multiple metals contribute to the overall economics. He explains:

• Antimony Value: Even a 0.1% antimony intercept is equivalent to 0.5% copper in value, significantly adding to the economics of a 17-meter intercept.
• Metal Equivalent Comparison: The average grade of the 17-meter intercept, on a metal equivalent basis, is approximately 30% higher than the resource grade of the Taylor deposit.
• Partner Validation: South 32, the project partner, is highly enthusiastic, with their Chief Development Officer publicly comparing Selena to the early stages of the Taylor deposit. This indicates the discovery meets their stringent criteria.
• Ongoing Drilling: Assays from only the top of the drill hole have been announced, with two more massive sulfide horizons pending, expected in the coming weeks.

Metallurgical Properties and Recoveries

The CRD deposits, while less mainstream than gold or copper deposits, are highly valuable due to their excellent metal tenor.

• Sulfide vs. Oxide: While oxide lead and zinc do not recover well in heap leaching, the new sulfide discovery exhibits excellent metallurgy.
• Recovery Rates: Metallurgy values from the Taylor deposit's feasibility study were used to calculate metal equivalents. Average recoveries for the Selena mineralization are estimated to be between 79% and 95% across all metals, which is considered exceptional.
• Byproduct Credits: The presence of multiple byproduct metals significantly adds to the back-end value of any intercept, though the market has primarily focused on zinc and silver.
• Silver Grade Expectations: While typical silver grades are over 100 g/t, the initial intercepts averaged 20-40 g/t. Ridgeline expects higher silver grades as they drill closer to the heart of the system.

Geological Model and Zonation at Selena

The SC25-053 drill hole has significantly refined the geological model for the Chinchilla sulfide CRD target.

• Thick Intercepts: The discovery hole encountered exceptionally thick intercepts, up to 17 meters, which are highly favorable for underground mining (typically 3-5 meters minimum thickness).
• Equivalent Grades: The equivalent grades within these thick intercepts meet the economic thresholds for both gold and silver deposits.
• Confidence in Higher Grades: Ridgeline is confident in drilling higher grades due to previous high-grade intercepts at the project and the positive feedback from South 32.
• MT Anomaly Confirmation: The MT anomaly, which is 2 km long by 1.5 km wide, is unequivocally confirmed to represent sulfide mineralization, not graphite or other false anomalies. This is a crucial validation for South 32.
• Southern Tip Discovery: The current discovery is at the southern tip of the 2 km anomaly, with ongoing drilling through the heart of it.
• Porphyry Influence and Zonation:
  • The initial discovery hole (SC25-053) was drilled very close to the porphyry, resulting in a zinc-rich "rind" of mineralization due to high temperatures.
  • Hole 54, drilled approximately half a kilometer northeast, is expected to move out of this high-temperature halo. This change in temperature is anticipated to facilitate the precipitation of other metals like gold, silver, and copper.
  • Ridgeline anticipates both lateral and vertical zonation. While zinc was dominant in the first hole due to proximity to the porphyry, they expect to find copper-rich and silver-rich zones as they move away.
  • Despite the zinc dominance in the initial intercept, Peters remains confident that Selena is fundamentally a primary silver deposit with significant byproduct credits.

Analogies to Other Major Deposits

The Selena project's geological setting and potential scale are being compared to well-established CRD systems.

• Structural Setting: The structural geology is similar to the Hilltop deposit (an I80 CRD discovery) located about 100 miles away.
• Scale and Zonation: The scale of the MT anomaly and the observed zonation patterns are very similar to the Hermosa deposit (Hermosa Taylor).
• Hermosa Comparison:
  • Ridgeline's original Chinchilla oxide discovery is analogous to Hermosa's outcropping oxide silver-manganese deposit.
  • The newly drilled Chinchilla sulfide is analogous to the deeper Taylor Deeps at Hermosa.
• Higher Gold Credit: A significant difference noted at Selena is the potential for a higher gold credit compared to Hermosa, with intercepts up to 1.5 g/t gold in the recent hole and up to 3 g/t gold in nearby areas. This is expected to materially add to the Net Smelter Return (NSR) value.

System Scale and Exploration Strategy

The scale of the MT anomaly at Selena is comparable to the Taylor deposit, suggesting a potentially massive system.

• MT Anomaly Scale: The size, scale, and intensity of the MT anomaly at Selena are almost one-to-one with the Taylor deposit.
• Targeting: Ridgeline is targeting a 50+ million ton system, which they believe is within range given the anomaly's scale and the consistent geological model.
• Structural Controls: The system is expected to comprise both stacked mantos (laterally extensive, thick zones) and structurally controlled chimneys (vertically continuous, high-grade feeder structures).
• Geophysical Refinement: Electrical conductivity readings are being taken during drilling to provide a "fingerprint" of the massive sulfide horizons. This data is fed back into the MT model for higher resolution and more efficient targeting in future programs.
• Drilling Plan:
  • The initial three holes are approximately 700 meters apart.
  • Hole 1 drilled from east to west, nicking the edge of the anomaly without significant grade.
  • Hole 53, drilled from west to east at the other end, hit the new discovery.
  • Hole 54 is positioned between these two, drilling from west to east, with a high likelihood of encountering significant mineralization based on the model.
  • Ridgeline anticipates needing approximately 10 widely scattered drill holes to define the geometry and controls of the high-grade zones.
• Depth of Exploration: The deepest part of the MT anomaly is around 1,000 meters, shallowing to 500 meters. This is considered more approachable than the Taylor deposit's depths. South 32 is willing to drill through the entire system to understand its full potential.

Partnership Structure and Financial Implications

The partnership with South 32 provides significant financial backing and de-risks the exploration for Ridgeline.

• South 32 Funding: South 32 is funding 100% of the exploration at Selena for the next four years, with an estimated $18 million in expenditures.
• Ridgeline's Financial Position:
  • Ridgeline is not funding any of the drilling at Selena and is making 10% of every dollar spent by South 32.
  • They are also seeing warrants exercised, eliminating the need to raise money at a depressed share price.
• Earn-in Structure:
  • Phase 1: South 32 must spend $10 million in the first five years to earn a 60% stake. They have spent approximately $4.5 million so far, with about $5.5 million remaining.
  • Phase 2 (Optional): If South 32 wants to earn up to 80%, they must spend an additional $10 million over three years.
  • Carried Interest: If South 32 earns 80%, Ridgeline retains a fully carried 20% interest to commercial production.
• Value of Carried Interest: The potential value of this 20% carried interest is substantial, especially considering the $3 billion estimated cost to bring the Taylor deposit into production. A 20% carried interest in a similar-sized deposit could be worth $600 million USD, with no further dilution to Ridgeline shareholders.
• Alternative for Ridgeline: If South 32 does not earn 80%, Ridgeline would own 40% of a potentially world-class CRD, which they could fund through loans or by bringing in a third party.
• Comparison to Swift Project: At the Swift project, Ridgeline is in year four of a five-year earn-in, having spent $11-14 million of a $20 million commitment. Significant discoveries are just starting to emerge, with limited funds remaining before a potential 60/40 JV. Selena offers a much longer runway for exploration and discovery with full partner funding.

Other Projects: Swift and Blackridge

Ridgeline has other projects with Nevada Gold Mines (NGM).

• 2024 Budget: A total of $9.5 million USD was budgeted for 2024 across all partner projects, with $3.5 million allocated to Selena and the remainder to Swift and Blackridge, funded by NGM.
• Swift Project:
  • Received approximately $5 million of the NGM budget.
  • The original plan was to drill five holes, but due to drilling deeper than anticipated, only two holes are expected to be completed this year.
  • Assays are pending on the completed holes.
• Lab Delays: Significant delays are being experienced at assay labs due to the high volume of work for NGM's Fourmile project. Assays for some holes have been waiting for over a month. Ridgeline has secured prioritization for their first hole samples, with results expected in the next week or two.
• Blackridge Project: Spending is also being managed by NGM.

Future Outlook and Budget

Ridgeline Minerals is well-positioned for significant growth, with substantial exploration budgets and strong partner support.

• Selena Drilling: Drilling at Selena will continue through January.
• 2025 Budget: Anticipated budget for Swift and Selena projects in 2025 is roughly $12 million USD, the largest in company history.
• Financial Independence: Ridgeline has no need to raise money due to warrant exercises and partner funding, allowing them to be selective in their advancement strategies and focus on the potential discovery at Selena.

Conclusion

The Selena project represents a significant discovery for Ridgeline Minerals, with the potential to be a world-class CRD deposit analogous to the Taylor deposit. Despite initial market skepticism due to the polymetallic nature of the mineralization, the strong validation from partner South 32, coupled with exceptional metallurgical properties and a clear geological model, points to substantial future value. The company's strategic partnerships and financial structure provide a robust platform for continued exploration and development, with significant upside potential for shareholders.
