Geology/Mineralization
The Cimarron Gold Project is situated within the prolific Porphyry Copper-Gold Belt of Sinaloa, Mexico, a region renowned for its high mineral endowment and established mining infrastructure. The property hosts the Calerita Zone, a porphyry gold-copper deposit with defined inferred resources and extensive geological potential.
Mineral Resource Highlights
- Calerita Zone:
- 3.7 million tonnes @ 0.65 g/t Au (Inferred)
- ~77,000 ounces of gold (Snowden, 2012)
- Drilling Completed:
- 13,246 meters across 106 holes (82 RC and 24 DDH)
Geological Setting
The Cimarron project is underlain by Laramide arc intrusive rocks, juxtaposed with Graben clastic sediments. This setting supports the development of multiple deposit styles across the property.
Key Mineralization Types Identified:
- Porphyry gold-copper mineralization (Calerita Zone)
- High-sulfidation epithermal systems (Lobo, Los Evanos, Monumentos, Huanacaxtle, Veteranos)
- Specularite-rich breccia veins
- Advanced argillic (lithocap) alteration systems
The Calerita Zone exhibits hallmark porphyry system features, including:
- Quartz-chalcopyrite-pyrite stockwork veinlets
- Disseminated mineralization in monzodiorite to quartz-monzonite intrusions
- Tourmaline and aplite breccias
- Potassic, sodic, and alkaline alteration
- Advanced argillic zones with residual vuggy quartz textures
Comparative Geology
Cimarron shares significant geological similarities with world-class porphyry deposits such as:
- El Gallo Mine, Sinaloa, Mexico
- Caspiche Deposit, Maricunga Belt, Chile
- Cadia Mine, New South Wales, Australia
These analogues further validate the project’s potential to host a +Moz gold deposit.
Geophysics & Alteration
Magnetic surveys over the property show strong contrasts that correlate with:
- Potassic and propylitic alteration halos
- Magnetite-rich metasomatic zones
- High-sulfidation epithermal zones
Spectral and geochemical analyses confirm alkaline alteration (Ca-Sr-F-Si-Fe), indicative of high-temperature, gold-bearing fluid systems.
