Denarius Metals Corp. (Cboe CA: DMET | OTCQX: DNRSF) has received results from its ongoing 10,000m surface infill diamond drilling programme at its Zancudo Project in Colombia. The results are from the final assays for 32 drill holes from the Los Albertos target, totalling approximately 4,790m. This infill drilling programme, which has been designed at 50×50m drill centres, commenced in late April 2024 and is aimed at upgrading inferred resources to the indicated category and to support near term mine development.
Drill highlights:
- 22.37g/t Au and 2,752g/t Ag over 0.40m from 61.70-62.10m, hole ZM-159, Manto Antiguo
- 53.51g/t Au and 154g/t Ag over 0.40m from 50.40-50.80m, hole ZM-156, Ortiz Vein System
- 37.60g/t Au and 1,190g/t Ag over 0.40m from 117.20-117.60m, hole ZM-154, Ortiz B Vein
- 25.94g/t Au and 245g/t Ag over 0.70m from 101.8-102.5m, hole ZM-151, Ortiz Vein System
- 17.53g/t Au and 380g/t Ag over 0.40m from 52.80-53.20m, hole ZM-162, Porvenir
Denarius’s drill programme focuses on two priority areas, Los Albertos and Las Brisas, which contain most of the existing mineral resources. The drilling programme started with the priority target, Los Albertos, with two drill rigs operating from eight purpose-built surface drill platforms. As of 27 July 2024, the drilling programme designed for the Los Albertos target was completed and the remaining meters planned for the Las Brisas target should be completed in the fourth quarter of 2024 with only one drill rig.
Serafino Iacono, executive chairman and CEO of Denarius Metals, commented, “We are very pleased with the drilling results achieved to date, which demonstrate that systematic, more tightly spaced, infill drilling at Los Albertos has produced very positive results with a best so far of 1.6m @ 7.74g/t Au and 890g/t Ag including 0.40m @ 22.37g/t Au and 2,752g/t Ag. These results confirm the results from previous drilling campaigns and have delineated a high-grade ore shoot, which is still open along strike and to the west, within the main Manto Antiguo structure that could enhance the resource estimate and production grade down the line. The drill programme is being carried out at tighter spacing, significantly de-risking the future production at the Zancudo underground operation, and further validates the modelling methodology used to derive the current mineral resource estimate.”
The infill drilling plan for the Los Albertos target was designed at 50×50m drill centres to intersect the Porvenir, Ortiz A and B veins and the Manto Antiguo structure. Los Albertos target comprises the following main structures: the steeply dipping El Porvenir Vein, set in the footwall of the northerly trending Santa Catalina master fault structure, the Ortiz Vein System that occurs in the footwall of the El Porvenir Vein and shows a similar structural trend, and the Manto Antiguo structure, which was the main structure historically mined.
Manto Antiguo is interpreted as a brecciated manto structure, hosting clasts that show thin layers of mineralization composed of quartz, pyrite, arsenopyrite, sphalerite, and galena, embedded in a matrix of sulphides and milled rock. This structure was selectively exploited by past mining, which focused on the sectors of the mine that showed the highest concentration of sulphides, allowing the company to evaluate and quantify an important resource that was left unexploited. A steeply dipping north-south trending reverse fault has been interpreted as offsetting the Manto Antiguo and Porvenir structures.
