InZinc Receives 5-Year Drill Permit Renewal and Provides Exploration Update at Indy Project in Central BC

In This Article:

Vancouver, British Columbia--(Newsfile Corp. - July 26, 2024) - InZinc Mining Ltd. (TSXV: IZN) ("InZinc" or the "Company") announces the renewal of a 5-year drill permit, with provisions for up to 60 drill holes, access trails and related work, was received July 18 for the Indy Sedex (zinc-lead-silver) project (100% interest) ("Indy" or the "Project") located 90 km southeast of Prince George, in central British Columbia.

On July 21 wildfire-related evacuation orders were issued and are in place for communities (Wells-Barkerville) and surrounding areas located to the south of the Project. The Company continues to monitor notices and developments. All InZinc crews are currently on a planned break and are absent from the project site.

Considering these developments, InZinc is re-evaluating the timing of the next phase of drill testing, notionally scheduled for this fall, at Indy. The Company is currently well positioned with working capital.

2024 Ground Exploration

Based on recent stratigraphic correlations1, the geological setting at Indy is highly analogous to that hosting mineral deposits in the prolific, metal-rich Selwyn Basin. To help guide the next drill campaign, InZinc completed additional geological mapping, soil geochemistry and rock sampling across the Main Trend area in June and early July. Soil and rock samples have been submitted for analysis with results anticipated in late August.

The Selwyn Basin, an 1100 km long sedimentary belt, hosts the world's second largest known accumulation of Sedex deposits, including some of the world's largest (see Table 1). Previously, the mineralized sequences of the Selwyn Basin were only known to extend from the Yukon into northeastern BC. The Indy project, located approximately 500 km south of the nearest known Selwyn Basin deposit, is particularly well located with respect to road, rail and power infrastructure (see Figure 1).
