Ridgeline Minerals Drills Massive Sulfide CRD Discovery at the Chinchilla Sulfide Target, Selena Project, Nevada
None
On November 4, 2025, Ridgeline Minerals announced a high-grade massive sulfide Carbonate Replacement Deposit (CRD) discovery at its Selena Project in Nevada. The discovery was made during the maiden drill program at the Chinchilla Sulfide target, which is being funded by partner South32 Limited.
Key drill intercepts from hole SE25-053 include: - 1.1 meters (m) grading 27.0% zinc (Zn), 60.1 g/t silver (Ag), 1.5 g/t gold (Au), 0.7% lead (Pb), and 0.4% copper (Cu). - 17.4 m grading 6.0% Zn, 35.6 g/t Ag, 0.2 g/t Au, 0.5% Pb, and 0.1% Cu.
The CEO, Chad Peters, stated that this discovery validates the company's geological model, which targeted a kilometer-scale magnetotellurics (MT) geophysical anomaly. He highlighted the potential to delineate a polymetallic CRD deposit of considerable scale and noted that drilling would continue through the end of the year.
The drill results announced on November 4, 2025, represent a material positive event for Ridgeline Minerals. This is not a routine exploration update but a legitimate new discovery.

Confirmation of Exploration Thesis: The company identified a large MT geophysical anomaly in late 2024/early 2025, theorized it could represent a large sulfide system, secured partner funding, and has now successfully intersected high-grade massive sulfide mineralization precisely within that target. This successful execution and validation of the geologic model significantly de-risks the Selena project.
-
Exceptional Grades: The intercept of 1.1 m at 27.0% zinc is exceptionally high-grade. The wider interval of 17.4 m at 6.0% zinc is also economically significant and suggests potential for a bulk-tonnage system. The polymetallic nature of the mineralization (zinc, silver, gold, lead, copper) adds to its potential value.
-
Partner Validation and Funding: The entire program is funded by major global miner South32 under an earn-in agreement. A significant discovery like this greatly increases the probability that South32 will continue to aggressively fund exploration to meet its US$10 million expenditure for a 60% interest. This provides Ridgeline with exposure to a major discovery without incurring the substantial cost and dilution of funding deep drilling programs.
-
Scalability: The discovery was made within a kilometer-scale geophysical anomaly. While this is just the first hole, it opens up a very large area for follow-up drilling with the potential to define a deposit of significant size.
-
Progression: Reviewing the historical news shows a systematic and logical progression. The company identified the target geophysically (Feb 2025), announced a partner-funded drill program (Apr 2025), commenced drilling (June 2025), and has now delivered a discovery. This demonstrates management's ability to execute its strategy effectively. The results from hole SE25-052A were weak, indicating geological complexity, but the discovery in hole -053 is the overriding factor.
The market was anticipating news, with the stock price trending up to a 52-week high just before the announcement. These results have the potential to justify that run-up and propel the stock higher.
Ridgeline Minerals is a discovery-focused precious and base metal explorer with a portfolio of six projects in Nevada. The company operates a hybrid prospect generator model, advancing its 100%-owned projects while partnering with major mining companies on others to reduce risk and preserve capital.
Following this discovery, the flagship project is clearly the Selena Project, a 39 km² land package in White Pine County, Nevada. Selena is prospective for silver-gold-lead-zinc Carbonate Replacement Deposits (CRD). The project is being advanced under an earn-in exploration agreement with a wholly-owned subsidiary of South32 Limited.
