InZinc Mining (TSX:IZN) has announced what it calls its strongest mineralized drill intersection to date at its 100 per cent-owned Indy Sedex Project in central British Columbia, with new drilling uncovering multiple shallow zinc, lead and silver-rich zones that could significantly enhance the project’s open-pit development potential.

Results from the company’s spring 2026 diamond drilling campaign at the B-9 Apex Zone have revealed a series of stacked mineralized horizons located within 100 metres of surface, extending the growing footprint of the B-9 mineralized trend. The discoveries build on the 2025 Apex discovery and strengthen the case for a large, near-surface conventional sulphide resource.

“Today’s drill results highlight not only our exploration success but two additional advantages on the horizon at Indy – ongoing discovery potential and an opportunity for potential open pit resources to lead the way,” InZinc’s CEO, Wayne Hubert said in a news release. “Additionally, Indy is a recent Sedex-style discovery in BC with 30 km of unexplored strata and roads connecting to the extensive logistics available in central and southern BC. These are distinct advantages, both for cost-effective exploration and for potential production of bulk metal concentrates.”

Best drill results to date

The standout result came from hole IB26-051, which intersected:

The interval included:

According to InZinc, the intercept represents the strongest “grade-times-width” result encountered at Indy since exploration began.

Additional shallow mineralization was intersected in surrounding holes, including:

Hole IB26-049

Hole IB26-050

Hole IB26-052

The company estimates true widths are approximately 80 per cent to 100 per cent of the reported downhole intervals.

Silver grades add new dimension

Beyond zinc and lead, drill results also highlighted growing silver potential at Apex.

One interval in hole IB26-049 returned:

Meanwhile, hole IB26-051 produced:

A single core sample from that hole assayed:

making it the highest silver assay recorded on the project to date.

The elevated silver values are interpreted as evidence of feeder-style mineralization, a geological setting often associated with stronger metal concentrations near mineralizing fluid pathways.

Coarse zinc mineralization encouraging

Geologists also reported extensive zones containing coarse crystalline sphalerite, the principal zinc-bearing mineral.

Several sections of hole IB26-051 contained sphalerite crystals reaching up to one centimetre in size. In mining operations, coarser-grained sulphide minerals can potentially improve metallurgical recoveries because they may be easier to separate during processing.

While metallurgical test work remains necessary, the company said the texture of the mineralization could ultimately support efficient zinc recovery characteristics.

Expanding open-pit opportunity

The discovery of multiple stacked mineralized zones close to surface is enhancing the potential for an open-pit mining scenario.

The new Apex discoveries lie along the broader B-9 Trend, a mineralized corridor that now extends more than 1,000 metres. InZinc believes the combination of shallow mineralization at Apex and the previously discovered B-9 Discovery Zone substantially improves the prospects for developing a sizeable near-surface resource.

Importantly, the trend remains open in multiple directions.

The area between Apex and B-9 Discovery has emerged as a priority exploration target, while geophysical and geochemical anomalies continue for an additional 1,200 metres to the northwest, offering significant room for future growth.

Deeper mineralization also confirmed

While much of the recent focus has been on shallow discoveries, drilling also encountered encouraging grades at depth.

Hole IB26-050 intersected:

Including:

The deeper intersections suggest mineralization continues below the newly identified shallow zones and may support a larger mineralized system than currently defined.

Infrastructure provides competitive advantage

Located approximately 90 kilometres southeast of Prince George, the Indy Sedex Project benefits from infrastructure advantages uncommon among early-stage exploration projects.

The property is accessible by upgraded forestry roads and lies near major transportation and power networks, including:

In addition, InZinc’s five-year exploration permit, renewed in 2024, still allows for up to 36 additional drill holes, providing substantial flexibility for continued expansion drilling.

Outlook

The latest drilling represents a significant milestone for InZinc as it continues to uncover higher-grade, near-surface zinc-silver mineralization at Indy. With its strongest intercept to date, growing evidence of metal-rich feeder systems, and a kilometre-scale trend that remains open for expansion, the project is increasingly positioning itself as a potential future source of critical zinc and silver in British Columbia.

Further drilling will be required to define the extent of the mineralized zones and determine whether the emerging discovery can evolve into a resource of meaningful scale. However, the latest results suggest Indy is becoming one of the more promising zinc exploration stories in Western Canada.
