XXIX Expands Opemiska's Regional Footprint

by Advancing the Pluto Property Option

Highlights:

Pluto adds copper-gold-silver exploration exposure near Opemiska without changing XXIX's core

focus on Opemiska and Thierry.

XXIX views the broader Opemiska district as highly prospective for copper-gold mineralization,

with Pluto adding new exploration targets that could benefit the Opemiska camp.

Recent forestry road development has improved access and may reduce the cost of initial

fieldwork.

Historical work indicates copper-gold-silver potential, which requires modern validation.

XXIX plans to compile historical data, complete reconnaissance mapping and prospecting, rank

targets, and assess whether trenching or drilling is warranted.

Toronto, Ontario--(Newsfile Corp. - September 17, 2026) - XXIX Metal Corp. (TSXV: XXIX) (OTCQB:

QCCUF) (FSE: 5LW0) ("XXIX" or the "Company") is pleased to announce that it has issued 287,403

common shares to Germanium Mining Corp., completing the share issuance required under the option

agreement (the "Option Agreement"). The Option Agreement provides XXIX with the right to acquire a

100% interest in the Pluto Property ("Pluto" or the "Property"), located approximately 10 km from the

Company's flagship Opemiska Project in Quebec's Chapais-Chibougamau region. The Option

Agreement was previously announced on

June 23, 2026

.

The Shares were issued at a deemed price of C$0.174 per Share, based on the 20-day volume-

weighted average trading price of the Company's common shares on the TSX Venture Exchange ending

September 8, 2026, in satisfaction of the C$50,000 share consideration required under the Option

Agreement. The Shares are subject to an applicable statutory hold period of four months and one day

from the date of issuance.

Following the issuance of the Shares, the Company's remaining obligation under the Option Agreement

is to complete exploration expenditures of at least C$250,000 on the Pluto Property on or before

December 31, 2028.

Pluto Complement to XXIX's Strategy in the Chapais-Chibougamau District

XXIX's strategy remains centered on advancing Opemiska and Thierry. Pluto is intended to be a

complementary addition to that strategy rather than a new development focus.

Pluto's proximity to Opemiska is relevant from a regional exploration and logistics perspective. If field

validation supports historical information, Pluto could provide additional early-stage exploration potential

around the Opemiska Project. At this stage, Pluto is not part of the Opemiska mineral resource or

development plan and will be advanced only if results justify further work.

About XXIX Metal Corp​.

XXIX is advancing its Opemiska and Thierry Copper projects, two significant Canadian copper assets.

The Opemiska Project, one of Canada's highest-grade open pitable copper deposits, spans 21,333

hectares in Quebec's Chapais-Chibougamau region, with strong infrastructure and nearby access to the

Horne Smelter. An October 2025 Preliminary Economic Assessment outlined a 12,500 tpd open pit

operation over a 17-year mine life, generating an after-tax NPV8% of $505M, IRR of 27.2%, and a 2.3-

year payback period ($4.35/lb copper price, $3,000/oz gold price, $30/oz silver price). The Thierry

Project hosts the K1 (near-surface) and the past-producing K2 (underground & surface) zones (see

XXIX news release dated October 1, 2024 for details regarding resources). Thierry has significant

infrastructure in place including an all-season road, an airport within 5km, a provincial power grid within

8km, and nearby rail. With these two high-potential projects, the Company has solidified its position as a

key player in the Canadian copper sector and has established itself as one of Eastern Canada's largest

copper developers.

Wherever possible, words such as "may", "will", "should", "could", "expect", "plan", "intend", "anticipate",

cause actual results, performance or achievements to differ materially from the results discussed or

implied in the forward-looking statements. Such factors include, among other things: the Company's

ability to satisfy its obligations under the Option Agreement; risks related to uncertainties inherent in drill

results and the estimation of mineral resources; and risks associated with executing the Company's

plans and intentions. Additional risk factors are described in the Company's disclosure documents

The reader is advised that the Preliminary Economic Assessment (PEA) summarized in this news

release is intended to provide only an initial, high-level review of Opemiska's economic potential. The

PEA mine plan and economic model include numerous assumptions and the use of inferred mineral

resources. Inferred mineral resources are considered to be too speculative to be used in an economic

analysis except as allowed for by NI 43-101 in PEA studies. There is no guarantee that inferred mineral

resources can be converted to indicated or measured mineral resources, and as such, there is no

guarantee Opemiska's economics described herein will be achieved. XXIX may be eligible for Clean

20, 2024. There is no guarantee the Company will be able to access the CTM-ITC.
