Vancouver, British Columbia--(Newsfile Corp. - July 9, 2026) - InZinc Mining Ltd. (TSXV: IZN) ("InZinc" or "Company") is pleased to announce completion of the spring 2026 diamond drill program with drill-core analysis underway at the 100% owned Indy Sedex (zinc-lead-silver-gallium-barite) project, well-located 90 km southeast of Prince George in central BC, Canada. The drill program followed-up on the discovery of the high-grade Apex Zone in 2025 (15.4% Zn, 1.3% Pb and 7.2 g/t Ag over 4.2 m including 20.1% Zn, 1.7% Pb and 9.5 g/t Ag over 3.2 m from 197.6 m downhole in Hole IB25-043), which successfully extended the B-9 mineralized trend to over 1000 m in strike length – remaining open for expansion (Figure 1).
As planned, the completed 2026 spring diamond drill program (7 holes, 1437 m) tested a 250 m strike (north and south) of the 2025 B-9 Apex Zone discovery and to a depth of 240 m. All drill core samples have been delivered to the laboratory and sample preparation and analysis are underway. Results are anticipated in the second half of July or early August, depending on lab turnaround time.
B-9 Apex Discovery
The high-grade, replacement-style Sedex mineralization at the B-9 Apex Zone was discovered in late 2025 with a 300 m step-out drill test of the northern extension of the near-surface 700 m long B-9 Zone. This achieved a 125% extension to over 1000 m in strike length of the B-9 Zone. Untested soil geochemical and EM geophysical signatures continue for at least another 1200 m to the northwest of the B-9 Apex Zone representing a high potential corridor for both extension and additional discoveries (Figure 2).

Indy – Easy Access, Infrastructure and Permitted
Indy is located about a 1.5-hour drive from Prince George, the major hub for transportation and heavy industry in central BC. The project is located 70 km south of the Yellowhead Highway (Hwy 16) and is accessed via recently upgraded forestry road and bridges providing direct access to the B-9 Zone.
Indy is located 85 km from the intercontinental Canadian National Railway (CNR), servicing the Port of Prince Rupert and connecting to the Port of Vancouver, and 35 km from hydro-electric transmission lines. Western North America's only zinc smelter complex is located approximately 500 km to the south of Indy in the city of Trail, BC.
