BMC Minerals has kicked off its 2026 drilling campaign at the Kudz Ze Kayah Project with a standout massive sulphide intercept at the Krakatoa Zone, pointing to potential extensions beyond current reserves and a longer mine life.
- 25.1m intercept grading 180g/t silver and 9.7% zinc at Krakatoa Zone
- Mineralisation remains open down plunge, indicating potential resource growth
- 2026 drill program targets multiple prospects near the proposed ABM Mine
- Exploration includes Fuego, GP4F, and Rhyolite Peak prospects
- Drilling staged to minimise environmental impact on local caribou herd
High-Grade Massive Sulphides Extend Beyond Current Reserve
BMC Minerals Ltd (ASX:BMC) has delivered an impressive start to its 2026 drilling program at the Kudz Ze Kayah (KZK) Project in Yukon, Canada, with drill hole K26-560 intersecting a thick, high-grade massive sulphide zone outside the current Ore Reserve. The hole returned 25.1 metres at 180 grams per tonne silver, 9.7% zinc, 1.0 g/t gold, 0.3% copper, and 3.4% lead from 327.5 metres depth, confirming continuity of mineralisation between historical drill holes and leaving the Krakatoa lens open down plunge to the north.
This result is particularly notable because it sits between two deep intercepts drilled in 2016, which themselves returned strong grades over substantial widths, suggesting a sizeable body of mineralisation remains to be delineated. The true width of the intersection is estimated at 19.8 metres, underscoring the thickness of the mineralised zone.
Expanding the Mine Life Near ABM Deposit
Managing Director Michael McClelland highlighted the significance of the find, stating it reinforces the company’s expectation that the Krakatoa Zone hosts thick, high-grade mineralisation beyond the current Ore Reserve. This bodes well for extending the mine life of the flagship KZK Project, which covers 372 square kilometres of highly prospective and underexplored tenure.
The 2026 drill campaign is ambitious, targeting multiple high-priority prospects within five kilometres of the proposed ABM Mine. Alongside Krakatoa, BMC is advancing drilling at the GP4F prospect and planning upcoming programs at Fuego and Rhyolite Peak. These targets have a history of copper-rich and silver-zinc mineralisation, with previous intercepts showing promising grades and widths that warrant follow-up.
Drilling is being carefully managed to minimise environmental impact, with helicopter-supported operations paused during critical caribou calving and rutting periods. This reflects BMC’s commitment to responsible exploration in the region.
Steady Flow of Results Expected as Program Advances
With assays pending from follow-up holes at Krakatoa and elsewhere, BMC anticipates a steady stream of results throughout the field season. The company’s approach is methodical, testing down-dip extensions and stepping out to define the limits of mineralisation.
Importantly, this drilling momentum follows BMC’s recent regulatory progress, including a positive permitting decision that clears the way for advancing the Kudz Ze Kayah Mine towards a 2027 Final Investment Decision. The project’s strong feasibility study and binding offtake agreements underpin its promising outlook, as detailed in the company’s positive permitting decision.
Exploration Strategy Targets Resource Growth and Mine Life Extension
The KZK Project’s geological setting is typical of volcanic-hosted massive sulphide (VHMS) deposits, with mineralisation hosted in felsic tuff and volcaniclastics. The Krakatoa Zone itself is a fault-bounded lens averaging 22 metres thick and open at depth, hosting a mix of silver-rich sulphosalts and base metals.
BMC’s 20,000-metre diamond drilling program is complemented by ground and airborne geophysics, as well as surface geochemical surveys, aiming to generate new targets and expand the resource base. The company’s systematic approach, combining historical data with modern techniques, seeks to unlock further value from this underexplored district.
Bottom Line?
While the initial high-grade intercept at Krakatoa signals potential resource growth, investors should watch for upcoming assay results and technical updates to gauge the extent and economic viability of these extensions.
Questions in the middle?
- Will follow-up drilling confirm the down-plunge continuity of the Krakatoa lens?
- How might results from the Fuego, GP4F, and Rhyolite Peak prospects impact the overall resource and mine plan?
- What are the timelines and capital requirements for advancing the Kudz Ze Kayah Project towards production?
