1 Estimated true widths are based on current interpretation of mineralized structures. |
The 2024 program continues with two diamond drills with nearly 9,000 meters and 27 holes completed to date. The 2024 exploration work has almost tripled the known strike length of D-Vein which is mineralized for approximately 1,275 meters. D-Vein is just one of several high priority targets at Columba and boasts some of the most striking results on the project to date. The current program is part of a fully funded follow up program of 20,000 meters, aimed to culminate in a maiden resource.
Prospective veins on the project are hosted within a volcanic caldera setting, the surface extent of mapped veins measuring roughly 4 kilometres by 3 kilometres. Management believes that Columba may be a newly recognized vein district that is nearly entirely preserved from erosion.
Drillholes CDH-24-167 and 168 were not expected to return significant mineralization as they were above the interpreted 'grade line' but are considered important for projecting the D-Vein below the grade line for future drill testing.

Sampling and QA/QC at Columba
All technical information for the Columba exploration program is obtained and reported under a formal quality assurance and quality control ("QA/QC") program. Samples are taken from core cut in half with a diamond saw under the direction of qualified geologists and engineers. Samples are then labeled, placed in plastic bags, sealed and with interval and sample numbers recorded. Samples are delivered by the Company to ALS Minerals ("ALS") in Chihuahua. The Company inserts blanks, standards and duplicates at regular intervals as follows. On average a blank is inserted every 100 samples beginning at the start of sampling and again when leaving the mineral zone. Standards are inserted when entering the potential mineralized zone and in the middle of them, on average one in every 25 samples is a standard. Duplicates are taken in the mineralized intervals at an average 2 duplicates for each hole.
The samples are dried, crushed and pulverized with the pulps being sent airfreight for analysis by ALS in
