InZinc Mining (TSXV: IZN) has announced a Phase 2 diamond drill program at its 100% owned Indy Sedex project in central British Columbia. The program follows successful Phase 1 results that extended the B-9 mineralized trend by over 40% to 700 meters in length.

Phase 1 drilling highlights include intersections of 11.0% Zn, 2.3% Pb and 27.1 g/t Ag over 3.0m from Hole IB25-029, and the widest intersection to date of 3.3% Zn, 0.7% Pb and 7.4 g/t Ag over 19.1m from Hole IB25-032. The project has also identified Gallium, a critical mineral.

The Phase 2 program, commencing around September 11th, will include 7-10 planned drillholes exploring northern and southern extensions of the B-9 trend. The project covers 200 square km of territory and is strategically located near essential infrastructure.

InZinc Mining (TSXV: IZN) ha annunciato un programma di perforazione diamantina di Fase 2 sul suo progetto Indy Sedex interamente controllato nel centro della Columbia Britannica. Il programma segue i positivi risultati della Fase 1, che hanno esteso la tendenza mineralizzata B-9 di oltre il 40%, portandola a una lunghezza di 700 metri.

Le programme de Phase 2, qui débutera vers le 11 septembre, comprendra 7 à 10 forages prévus pour explorer les extensions nord et sud de la tendance B-9. Le projet couvre 200 km² et est stratégiquement situé à proximité d'infrastructures essentielles.

InZinc Mining (TSXV: IZN) hat ein Phase-2-Diamantbohrprogramm für sein zu 100 % im Besitz befindliches Indy Sedex-Projekt in Zentral-Britisch-Kolumbien angekündigt. Das Programm folgt auf erfolgreiche Phase-1-Ergebnisse, die den mineralisierten B-9-Zug um über 40% auf eine Länge von 700 Metern erweiterten.

Vancouver, British Columbia--(Newsfile Corp. - September 9, 2025) - InZinc Mining Ltd. (TSXV: IZN) ("InZinc" or the "Company") is pleased to announce a Phase 2 2025 diamond drill program will commence in September at its 100% owned Indy Sedex (zinc-lead-silver-barite) project, well-located 90 km southeast of Prince George in central British Columbia, Canada. Drilling will follow up on a successful Phase 1 program (11 holes, 1089 m) that extended the B-9 mineralized trend by over 40% to 700 m in length.

The B-9 trend remains open for further exploration along trend and at depth. Untested soil geochemical and EM geophysical anomalies continue for at least 750 m to the north of the B-9 trend. Drilling to-date has tested just 10% of the prospective 7.5 km Main Trend (Figure 1).

Phase 2 Drilling

Drilling is planned to recommence on or around September 11th. An additional 7 to 10 planned drillholes will explore for the northern and southern extensions of the B-9 trend.

Highlights of Phase 1 Drilling Results

In Phase 1, shallow drilling extended the near surface B-9 mineralized trend from 450 m to greater than 700 m in length. All 2025 drill holes across the B-9 trend reported mineralization at the principle mineralized horizon with nine holes returning mineralization above grade/width cut-off criteria (>1% Zn over 2 m). All intersections defining B-9 mineralization, including drilling prior to 2025, occur within 120 m of surface.

Near surface massive sulphides averaging 11.0% Zn, 2.3% Pb and 27.1 g/t Ag over 3.0 m from 61.0 m downhole were intersected in Hole IB25-029 (news release August 18, 2025). Gallium, a critical mineral, was also identified in a massive sulphide sample from Hole IB25-029.

The widest intersection to date averaging 3.3% Zn, 0.7% Pb and 7.4 g/t Ag over 19.1 m from 29.9 m downhole, including a high-grade zone averaging 8.5% Zn, 2.1% Pb and 21.3 g/t Ag over 2.0 m from 31.0 m downhole, was intersected in Hole IB25-032 (news release August 21, 2025). The intersection is located 30 m up-dip (west) of the 2018 massive sulphide discovery (IB18-009, news release November 13, 2018) averaging 8.0% Zn, 2.0% Pb, and 16.2 g/t Ag over 9.9 m from 78.1 m downhole.

The continuity of the principle mineralized horizon has been demonstrated to a depth of 120 m in Hole IB25-038 (3.3% Zn, 0.3% Pb, 2.6 g/t Ag over 4.2 m) and remains open down-dip (news release September 4, 2025). In the same hole, a second, shallower mineralized horizon was intersected (3.2% Zn, 0.4% Pb, 2.6 g/t Ag over 3.2 m from 86.6 m downhole) and is also present in adjacent drill holes to the north and south. The mineralized envelope is recognized by its distinctive "radiolarian" type replacement mineralization.

Sedex District in Central BC

The extensive tenure at Indy covers 200 square km and a 30 km length of under-explored strata in central British Columbia. The project is well located with respect to road, rail, power, port and smelter infrastructure.

The near surface mineralization (zinc-lead-silver and barite) discovered across the 7.5 km Main Trend is typical of worldwide Sedex deposits and districts. These deposits often include significant silver and critical minerals as by-products.

About InZinc

InZinc is an active explorer at its Indy Sedex project (100%) in central British Columbia, Canada. The Company is exploring near surface zinc-lead-silver and barite mineralization discovered at Indy in a new, under-explored mineral region analogous to the prolific Selwyn Basin of northeastern BC and the Yukon. South32 Limited (ASX, LSE, JSE) became a major tenure holder in the Indy belt by staking approximately 200 km2 of adjacent claims in late 2021. Through its equity investment in American West Metals (ASX) and a 50% royalty interest (NSR) from any future production of indium mined at American West's West Desert project, InZinc is also exposed to a portfolio of North American base metals and precious metals projects.

Quality Assurance/Quality Control

HQ drill core was collected from the drill site and delivered to the Indy Camp by InZinc staff. The core was logged, sample intervals were outlined and photographic records were collected. Core samples were split using a diamond saw or manually chipped at the camp with one-half of the core submitted for assay and the remainder stored in wooden core boxes. The core was bagged in individually marked plastic sample bags and shipments were compiled in labelled rice bags. Core shipments were delivered by InZinc contract geologists to Bandstra Transportation Systems Ltd. in Prince George, B.C. for furtherance to MSA Labs in Langley, B.C., Canada for analysis. Samples were prepared by MSA and analyzed by ICP-AES multi-element plus 4-Acid Digestion and select AAS-Fire Assay. In addition to the labs QA/QC procedures, InZinc inserted blind standards, blanks or lab-directed duplicates by special instruction - every tenth sample. The results from the QA/QC samples were within industry norms.
