Out Group Company for Silver and Gold (TSX: O.C.G; OTCC: okgsf; DE:MRG) announced additional drilling results from the Guadual target at its 100%-owned Santa Ana silver project in Colombia. The results confirm the continuity of mineralization within the main structure and further define the geometry of the mineralized buds within the system.
Highlights: Intersection DH567 with an estimated true width (ETW) of 0.84m grading 2,844 g/t AgEq (2,505 g/t Ag and 3.84 g/t Au).
DH593 intersected 1.17 m ETW grading 1,889 g/t AgEq (1,287 g/t Ag and 6.83 g/t Au), indicating consistency of mineralization within the interpreted dip zone.
DH587 returned 6.85 m ETW grading 227 g/t AgEq (167 g/t Ag and 0.68 g/t Au), indicating broader mineralization intervals within the system.
Drilling continues at Guadual to confirm the continuity of the main mineral structure and further identify mineral buds within the target.
At Guadual, recent drilling was designed to test and extend a mineralized zone interpreted to dip approximately 45 degrees, based on previously reported drilling that demonstrated the continuity of the system. The present results confirm the continuity of the main structure and further identify mineral buds within the target through a combination of incremental drilling and drilling.
Vein intercepts returned consistent grades and widths across multiple drill holes, supporting the interpretation of high-grade continuity within this sinking zone. Wider intervals, including 6.85 meters of estimated true width of 227 g/t AgEq (167 g/t Ag and 0.68 g/t Au) in hole DH587, coupled with high-grade intersections such as those observed in holes DH567 and DH593, indicate a well-defined mineralization system with continuity of grade and thickness.
“Recent drilling results from Guadual continue to demonstrate the consistency and continuity of mineralization in one of our key target areas in Santa Ana,” commented Rob Brueggemann, President and CEO. “Drilling improves our understanding of the geometry of the mineral buds, including an area of constant dipping, and further enhances the geological model that supports the ongoing resource identification at the project.”
Continuing drilling and geological modeling are improving the definition of vein geometry, including the orientation and extent of mineral undergrowth. These results are integrated into the company’s geological interpretation and resource modeling work, taking into account verification and estimation criteria.
The latest results from Guadual build on previously reported drilling and continue to improve the company’s understanding of the structural controls, geometry, and distribution of mineralization within the Santa Ana Project. The consistency of the grades and widths observed across the target supports the interpretation of a coherent mineralized system and provides additional support for the continuity of mineralized buds at depth.
These results also contribute to the continuous improvement of the company’s structural and geological model, including the definition of mineral domains and their spatial relationships within the vein system. The latest Guadual drilling results are expected to be incorporated into the company’s geological interpretation and resource modeling work, supporting an updated mineral resource estimate expected later this quarter.
The Santa Ana Project extends over 28,000 hectares within the Marqueta region, encompasses both titles and applications, and is recognized as the largest and highest primary silver area in Colombia, with mining records dating back to 1585.
The first Santa Ana resource estimate, detailed in Technical Report NI 43-101 dated June 8, 2023, prepared by AMC Mining Consultants, indicates an estimated indicated resource of 1,226,000 tonnes containing 24.2 million ounces of silver equivalent grading 614 g/t and an inferred resource of 966,000 tonnes containing 13.5 million grading ounces. 435 grams/ton of silver equivalent.
The identified resources span seven major vein systems involving multiple parallel veins and mineralized shoots: Santa Ana (San Antonio, Roberto Tovar, San Juan shoots); La Porvia (La Ivana); El Dorado (El Dorado, La Abeja shoots); Paradise (Megawell); Maras. Los Naranjos and La Isabela.
The current drilling campaign has expanded the extent of known mineralization and tested additional target areas within the 17-kilometre fully permitted mineral corridor of the Santa Ana Project. Since the start of the current campaign, drilling has confirmed mineralization in six vein systems – Aguilar, Jiménez, La Ye, Los Mangos, Guadual and Morena – through a combination of step drilling, testing and delineation. The results of these programs are incorporated into updated geological interpretations and 3D models. They will support ongoing drilling activities and prepare the next update to the Mineral Resource Estimate.
