- Dateline Resources (OTC:DTREF) reveals potential expansion of gold and REE resources at the Colosseum Project in California.
- The current JORC-2012 compliant resource stands at 27.1 million tons, with 1.1 million ounces of gold.
- An economic assessment reports a Net Present Value (NPV) of US$550 million and an Internal Rate of Return (IRR) of 61% at a gold price of US$2,900/oz.
Dateline Resources Limited (OTC:DTREF) has provided an update on its Colosseum Gold and Rare Earth Element (REE) Project in California, highlighting promising geological findings that could significantly enhance the project's resource base. The current mineral resource at the Colosseum Project is JORC-2012 compliant, consisting of 27.1 million tons at a grade of 1.26 g/t gold, totaling 1.1 million ounces. This includes 455,000 ounces classified as Measured, 281,000 ounces as Indicated, and 364,000 ounces as Inferred.
The recent economic assessment conducted in May 2025 outlines a strong economic potential for the project, reflecting a Net Present Value (NPV) of US$550 million and an Internal Rate of Return (IRR) of 61%, assuming a gold price of US$2,900 per ounce. These metrics underline the project's profitability and underline its strategic significance.
The company's investigation into existing geological data has revealed gravity low anomalies that align with historically mined breccia pipes and newly identified felsite outcrops. This correlation suggests potential for additional breccia pipes, indicating that the known deposits might only represent the upper portions of a more extensive mineralized system.
Starting in June 2025, Dateline plans to launch an extensive exploration program. This will include a soil geochemical survey and a magneto telluric (MT) geophysical survey aimed at mapping subsurface structures and identifying additional REE-bearing zones. A dedicated REE drilling program is also in development to target high-priority areas, which will help define the presence and extent of further gold and REE mineralization.
Located within California's Walker Lane Trend and mere kilometers from the Mountain Rare Earth mine, the Colosseum Project is strategically positioned for REE exploration. The combination of existing resources, fresh geological insights, and planned exploration activities supports the potential for significant resource expansion at the site.
