“Hole 57 is a Discovery Hole”: Scorpio Gold Hits at Black Mammoth Target explains Leo Hathaway

Key Concepts

• Manhattan District: A 13-kilometer-long gold trend in Nevada, historically significant and located 14 km south of the Round Mountain mine.
• Reliance Fault: The primary structural control for mineralization in the district.
• Jasperoid Breccias: Silicified rock formations often associated with gold mineralization; key targets for "leakage" from deeper feeder zones.
• Inferred Resource: A mineral resource estimate with a lower level of confidence, used here as a primary growth metric.
• Cap Rock: Geological layers that trap mineralizing fluids, potentially leading to high-grade ore bodies.
• Step-out Drilling: A method of drilling at set intervals (e.g., 50m) from a known discovery to define the extent and morphology of an ore body.

1. Project Overview and Strategy

Scorpio Gold is focused on the Manhattan District in Nevada, a region with a history of mining dating back to the late 19th century. The company’s strategy, led by Executive Technical Director Leo Hathaway, mirrors the "Lumina model":

• Resource Expansion: Aggressively grow the inferred resource toward a 2-million-ounce target.
• Technical De-risking: Simultaneously gather data to facilitate a Preliminary Economic Assessment (PEA) to provide the market with clear economic parameters.
• Modern Exploration: Applying modern geological models to a district that has seen little deep or systematic drilling despite its historic production.

2. Key Exploration Targets

• Black Mammoth: A prominent hill featuring jasperoid breccias and historic workings. It is considered a high-priority target because it sits on the Reliance Fault. The team believes the surface mineralization is "leakage" from a deeper, high-grade feeder zone trapped beneath cap rocks.
  • Discovery Hole 57: Intersected 43 meters of over 1 g/t gold starting at 195 meters downhole. The team views this as a discovery hole and is currently conducting 50-meter step-outs to define the mineralization.
• Iron Queen: Located at the southern end of the trend. Recent diamond drilling confirmed the resource model and identified mineralization in areas previously untested by historic RC (Reverse Circulation) drilling.
• Future Targets: The company has identified approximately 18 targets, including Keystone and Jumbo, which are being systematically ranked and prepared for future drill testing.

3. Methodologies and Operational Processes

• Diamond Drilling: The company is prioritizing diamond drilling over historic RC methods to obtain better geological data, which is essential for understanding the complex folding and thrusting of the Cambrian-age rocks.
• Underground Access: Scorpio is leveraging existing permitted underground workings (Gold Wedge deposit) to drill targets like Black Mammoth more efficiently and cost-effectively.
• Systematic Data Compilation: The team is currently compiling historic data across the 13km trend to rank targets for future drilling.
• Land Management: CEO Zayn Callian emphasized strict diligence regarding claim maintenance, including updated title opinions, to mitigate jurisdictional risks.

4. Notable Quotes

• Leo Hathaway on Hole 57: "Hole 57's a discovery hole. It confirms the idea and we might have just clipped the edge of something."
• Leo Hathaway on the geological model: "It's a good scenario to find a high-grade ore body where you see lots of leakage and you're right along strike from a potential feeder zone and you're in the cap rocks that nobody's really drilled through."
• Zayn Callian on valuation: "As long as we can keep our head down, drill aggressively, work towards that 2 million ounce target... I think the market will ultimately realize that even today we remain undervalued."

5. Research and Historical Context

• The "April Fool" Discovery: The district’s history dates back to a shepherd who discovered gold on April 1st in the late 1800s, leading to a massive staking rush.
• Proximity to Round Mountain: The Manhattan District is located near Kinross’ Round Mountain mine, which has produced 15–16 million ounces of gold, providing a strong regional precedent for large-scale mineralization.

6. Synthesis and Conclusion

Scorpio Gold is executing a systematic, data-driven exploration program in a proven, low-risk jurisdiction (Nevada). By combining the expansion of existing resources with the testing of high-potential, deep-seated targets like Black Mammoth, the company aims to reach a 2-million-ounce inferred resource. The transition from historic, shallow mining to modern, deep-drilling exploration—supported by the "Lumina model" of rapid economic assessment—positions the company to potentially unlock significant value in an overlooked district. The immediate focus remains on the aggressive drill cadence and the upcoming release of results from the current batch of holes at the lab.
