Kootenay Reports Wide High-Grade Intercept with Aggressive 400 Meter Step Out.
D-Vein Strike Length, Now Drilled To 1,080 Meters at
- Hole CDH-24-164
- 98.7 meters downhole length averaging 211 g/t silver, 0.1% lead and 0.4% zinc downhole includes:
- 350 g/t silver, 0.2% lead and 0.5% zinc over 38 meters
- 531 g/t silver, 0.1% lead an 0.2% zinc over 11 meters
- Aggressive 400-meter step out of CDH 24-153 reporting a core length of 40.5 meters of 183 g/t silver including 11 meters of 481 g/t silver along the 1600 meter elevation line. See news release dated
May 21 st, 2024. - True widths for the new interval are difficult to estimate as the zones encountered in hole 164 mark a change to a more disseminated style hosted in a dark rhyolite.
- It is not yet clear if the interval is parallel to the steep dipping D vein structure, is a zone of thickening around it or some other shallowly dipping feature. If it is parallel then the true width is about 50% of drilled width. It variably contains microfractures, hydrothermal breccias, quartz-barite veinlets with patches of galena and sphalerite and disseminated hematite. It is occurring near the projected intersection of D and B vein trends.
- 98.7 meters downhole length averaging 211 g/t silver, 0.1% lead and 0.4% zinc downhole includes:
Reporting 11 more holes that were designed as large step outs to find the unknown edge of the wide high grade silver intercepts. Key take aways:
- Drilling confirms the vertical zonation pattern of increasing grades to depth with best grades below 1750 meters above sea level.
- D-Vein strike length now extended to 1,080 meters between holes
- CDH 24-164 represents an aggressive 400 meter step out from CDH 24-153
- Known length increases from 450 meters at the commencement of 2024 drilling to1080 meters currently.
- Drillholes CDH-24-164 and CDH-24-163 extend known mineralization and support vertical zonation patterns observed along the trend with significant grade increase reported in CDH 24-164.
- Hole CDH-24-163 intercepted a well-developed vein with stockwork over 17.5 meters (12.67 e.t.w).
- Hole CDH-24-164 intercepted a similar zone on. The same section as CDH 24-163 at greater depth where thicknesses and grades are noticeably higher
- All holes hit the D-Vein structure except CDH-24-155 which drilled a different target and CDH-24-158 which encountered drilling problems and was unavoidably abandoned before reaching target depth.
- New potential high grade stockwork in footwall of D-Vein
- CDH-24-161 with 1,595 gpt silver over 0.4 meters (e.t.w. 0.33 meters) within 337 gptsilver over 2.5 meters (2.07 meters e.t.w.)
- Broad intervals of medium grade in stockwork zones
- CDH-24-156 with 11.57 meters (e.t.w. 5.6m) of 127 gpt silver includes 0.82 meters (t.w. 0.39m) of 419 gpt silver
- CDH-24-160 with 11 meters (e.t.w. 6.74 m) of 78 gpt silver
- CDH-24-161 with 9.2 meters (e.t.w. 7.6m) of 81 gpt silver
- Widely spaced exploration holes of 100 to 200 meter confirming vein continuity along strike and down dip.
- Excellent down-dip continuity demonstrated by new sections containing holes CDH-24-161 and 162, holes CDH-24-156 and 157 and holes CDH-24-163 and 164). See below for links to cross-sections.
- D-Vein remains open along strike to the southeast and down dip.
Results from holes CDH-24-154 to CDH-24-164 are tabulated below and represent mineralized sections of D-Vein as well as adjacent zones of stockwork veining in addition to parallel and cross cutting veins. The current work at D-Vein is wide spaced and has intercepted the vein over a horizontal length of 1,080 meters, to a maximum vertical depth of 1550 meters above sea level. A single hole reported, CDH-24-158, herein became stuck in a fault zone before reaching target and was abandoned.
The ongoing 2024 program comprises 5,153 meters in 17 holes and has more than doubled the known strike length of D Vein, one of several high priority targets at Columba boasting 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 delineate a maiden resource expected in late 2024.
Current batch of drill results are tabulated herein and drill highlights, maps and sections from the project are tabulated on the Company's website at the links below

The company has completed 35,487 meters of diamond drilling in 164 holes at Columba since 2019 and intercepted numerous veins with high silver grades and widths indicating excellent resource potential. 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.
A comprehensive list of drill results completed on the Columba Property since 2019 may be viewed here: Columba Drill Results.
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
