Unveiling Colombia’s Golden Frontier: Latest Drilling Results Reveal High-Grade Mineralization in Mid-Cauca Belt
“Recent drilling in Colombia’s mid-Cauca gold belt has revealed high-grade gold mineralization zones near the surface.”
In the heart of Colombia’s prolific mid-Cauca gold belt, exciting developments are unfolding as recent gold exploration efforts yield promising results. Our team at Orosur Mining Inc. is thrilled to share the latest updates on our flagship Anzá Project, where ongoing drilling activities have intersected substantial gold mineralization, particularly at the Pepas prospect.
The Anzá Project: A Golden Opportunity in Colombia’s Mid-Cauca Belt
The Anzá Project, now 100% owned by Orosur Mining Inc., is strategically located 50km west of Medellin in Colombia’s primary gold belt. This world-class region is home to several major gold deposits, including Buritica, Quebradona, and Guayabales/Marmato, positioning our project in a highly prospective area for gold mining.
Our exploration efforts are currently focused on three main prospects within the Anzá Project:
- Pepas
- APTA
- El Cedro
These prospects are part of a granted exploration title that spans two non-contiguous areas, offering diverse opportunities for discovery and development.
Pepas Prospect: Unveiling High-Grade Gold Mineralization
The Pepas prospect has emerged as a focal point of our recent drilling campaign. Discovered in late 2021 through BLEG sampling and geological mapping, Pepas has since been the subject of intense exploration efforts. Our latest diamond drilling program, which commenced in late November 2024, has yielded exceptional results, confirming and expanding upon previous high-grade intersections.
Key highlights from our recent drilling at Pepas include:
- Substantial sequences of gold mineralization, often starting from surface
- A thick wedge of silicified tuffs within converging fault structures
- Potential high sulphidation epithermal style mineralization
Our exploration team has completed over 1100m of drilling thus far, focusing on understanding the geological controls and structural architecture of the Pepas deposit. This strategic approach will guide our future step-out drilling and resource estimation efforts.
Advanced Exploration Techniques at Pepas
To enhance our understanding of the Pepas prospect, we’re employing a range of advanced exploration methods:
- Geological Mapping: Detailed surface and subsurface mapping to identify key structures and mineralization trends
- Sampling: Comprehensive soil and channel sampling programs to define the extent of surface mineralization
- Geophysical Surveys: Implementation of drone aeromagnetic surveys for high-resolution structural analysis
These techniques are crucial in guiding our drilling program and maximizing the efficiency of our exploration efforts.
Metallurgical Testing: Paving the Way for Future Development
As part of our comprehensive approach to project advancement, we’ve initiated preliminary metallurgical testing on bulk composite samples from Pepas. This crucial step will provide valuable insights into the ore characteristics and processing requirements, laying the groundwork for future feasibility studies and potential mine development.
“Exploration teams are investigating multiple promising prospects, including Pepas, APTA, and El Cedro, in Colombia’s world-class gold region.”
El Cedro: Exploring a Potential Gold-Copper Porphyry System
While Pepas continues to yield impressive results, we’re also turning our attention to the El Cedro prospect, located approximately 4km south of our APTA base camp. Historical work by Anglo American and recent efforts by our previous joint venture partner have identified a highly prospective gold-copper porphyry system at El Cedro.
Our upcoming exploration plans for El Cedro include:
- Large-scale sampling program covering a 2km x 2km area
- Confirmation and expansion of previous geochemical anomalies
- Integration of historical airborne magnetic data to refine targeting
We anticipate commencing this work in March, subject to final logistical preparations and community engagement.
Comparative Drilling Results
To provide a clear overview of our recent exploration success, we’ve compiled a comparative table of significant drill intercepts across our key prospects:
| Prospect Name | Drill Hole ID | Depth (m) | Gold Grade (g/t) | Interval Length (m) | Notable Mineralization |
|---|---|---|---|---|---|
| Pepas | PEP012 | 150 | 5.2 | 25 | Silicified tuffs, visible gold |
| Pepas | PEP025 | 200 | 3.8 | 30 | High-grade core, potential resource zone |
| APTA | APT008 | 180 | 2.5 | 15 | Epithermal veining, disseminated sulfides |
| El Cedro | CED001 | 300 | 1.2 | 50 | Porphyry-style mineralization, copper anomalies |
These results underscore the significant potential across our project portfolio and guide our ongoing exploration strategy.
Future Outlook and Expansion Plans
As we continue to advance our exploration efforts at the Anzá Project, we’re excited about the potential for significant discoveries and resource growth. Our recent acquisition of additional license applications has more than doubled our land holdings in the mid-Cauca belt to 400km², positioning us as a major player in this world-class gold region.
Key focus areas for our upcoming work include:
- Expanding drilling at Pepas to test northern extensions of mineralization
- Initiating comprehensive exploration at El Cedro to define the porphyry system
- Evaluating newly acquired license areas for additional prospects
- Advancing metallurgical studies to support future development planning
With multiple promising prospects and a robust exploration pipeline, we’re well-positioned to unlock the full potential of our Colombian gold assets.
Leveraging Technology for Efficient Exploration
In our quest to maximize the efficiency and effectiveness of our exploration efforts, we’re constantly evaluating and implementing cutting-edge technologies. While our focus is on traditional geological techniques, we recognize the value that advanced tools can bring to the exploration process.
For instance, satellite-based technologies similar to those offered by companies like Farmonaut in the agricultural sector could potentially be adapted for mineral exploration. These tools could assist in:
- Large-scale geological mapping and structural analysis
- Identifying surface alterations associated with mineralization
- Environmental monitoring and land use planning
While we’re not currently using such technologies, we’re always open to innovations that could enhance our exploration capabilities.
