InZinc Identifies Rare Earth Elements with Nickel-Cobalt-Copper Discovery at Keel Red and

Commences Drilling at Indy Project, BC

Vancouver, BC – InZinc Mining Ltd. (TSX-V: IZN) (“InZinc” or the “Company”) is pleased to report the identification

of rare earth elements associated with the nickel-cobalt-copper discovery at Keel Red in 2022 and announce

commencement of the fully funded 2023 drill program at the Indy p roject (100% interest) (“Indy” or the “Project”)

located 100 kilometres (km) southeast of Prince George in central British Columbia.

Rare Earth Elements – Discovery at Keel Red

Subsequent to the discovery of nickel-cobalt-copper mineralization at Keel Red in 2022 (news release January 25,

2023), the mineralized 27.1 m interval of diamond drill hole IB22 -020 has been a nalyzed for rare earth element

(REE) content. In drill hole IB22-020, the entire 27.1 m of buried oxide material starting at 47.3 m downhole has

returned 363 ppm total rare earth oxides (TREO), (Table 1).

In addition, and within the above 27.1 m interval:

• The heavy rare earth oxides (HREO) comprise approximately 60% of the average TREO content over the

27.1 m interval.

• A higher grade REE bearing downhole interval from 61.0 m to 68.0 m averages 529 ppm TREO over 7.0 m.

• The highest REE bearing interval, from 66.0 m to 67.0 m downhole, returned 784 ppm TREO over 1.0 m.

The red, clay-rich host containing the nickel-cobalt-copper and REE mineralization at Keel Red, with its relatively

high HREO content, distinguishes Keel Red from the more common REE bearing occurrences known elsewhere in

British Columbia. Interpretation and e xtension of the shallow Keel Red mineralization will be a priority during the

2023 drill program.

* Previously released (news release January 25, 2023).

** Total rare earth oxides include oxides of 15 heavy and light rare earth elements including yttrium, as defined by the USGS, 2018.

Standard element to oxide conversion factors have been used in the calculation of rare earth oxide values from elemental assa y values.

For the TREO composite results tabled above, MSA Labs of Langley, BC conducted multi-element determination of the mineral samples (46 continuous,

downhole) using a lithium borate fusion and inductively coupled plasma -mass spectroscopy (ICP-MS) finish (laboratory coded as IMS-300).

Note: Drill intervals represent apparent width. True widths are unknown.

2023 Priority Drill Targets

The 2023 drill program includes plans for between 8 to 12 reverse circulation drill holes over approximately 600 m

of the Keel Red and Echo North trends in the north ern area of the Main Trend (Figure 1). Other targets will be

considered for drilling, time permitting. The program is anticipated to be completed by late September.

Nickel – Cobalt – Copper and Rare Earth Element Targets

• Keel Red: In 2022, diamond drill hole IB22-020 intersected 27.1 m of buried red clay rich material starting

at 47.3 m downhole and averaging 0.67% zinc and 0.13% nickel . The upper part of the core interval (from

47.3 m to 55.0 m) also returned 0.11% copper over 7.8 m. Additionally, the 27.1 m interval returned cobalt

content averaging 163 ppm including values up to 962 ppm (0.10%) over a 1 .0 m core length . Further

analysis returned 363 ppm TREO over the 27.1 m interval including higher grades of up to 784 ppm TREO

over 1.0 m.

• Fox Ni: The new Fox Ni target, located 550 m northwest of Keel Red, comprises a 350 m long high contrast

geochemical target (>95 percentile), coincident nickel-cobalt-copper in soil signal.

• TJ: The TJ target, identified in 2022 and located 425 m west of Keel Red, comprises a 500 m lon g, high

contrast (>95 percentile), coincident nickel-cobalt-copper in soil signal.

• Delta Ni: The Delta Ni target, identified and located 100 m east of the Delta Horizon, comprises a 600 m

length of high contrast (>95 percentile), coincident nickel-cobalt-copper in soil signal.

Multi-Metal Targets

• Echo North: The 1.9 km long Echo target is a continuous high contrast, multi -element (Zn, Pb, Ba

signatures) soil geochemical anomaly discovered in 2021. Echo North comprises an area 400 m by 250 m

defined, principally, by its strong Zn-Pb-Ba in soil signatures. Additional strong nickel -cobalt-copper surface

geochemical signals also occur across the western flank of the Echo North target and are included for drill

testing in 2023.

About InZinc

InZinc is an active explorer and, through its Indy project (100% interest), equity and royalty interests, is exposed to

a diverse portfolio of active North American base metals and precious metals projects. The Company has

discovered and continues to explore for expansion of near surface zinc, nickel-cobalt-copper and rare earth element

mineralization at the easily accessible Indy project located in a new and under-explored mineral region of central

British Columbia, Canada. A Canadian subsidiary of South32 (ASX, LSE, JSE) became a major tenure holder in

the belt by staking approximately 200 km2 of adjacent claims in late 2021. InZinc has a significant equity investment

in American West Metals (ASX) which is advancing multiple North American base metals projects. In addition,

InZinc has a production royalty and will receive 50% of the revenue (NSR) from the sale of indium mined from

American West’s West Desert project.
