Lux Metals to Acquire High-Grade Gold La Grande Project in Quebec

Vancouver, British Columbia - Lux Metals Corp. (TSXV: LXM) (“Lux” or the “Company”) is pleased to

announce that it has entered into an option agreement dated November 10, 2025 (the “Option

Agreement”) with La Pulga Mining Corp. (the “Optionor”) to acquire an undivided 100% interest in the

La Grande Project (“La Grande” or the “Project”), a high-grade gold project, located in the James Bay

region of Québec (see Figure 1) (the “Transaction”).

The Project is transected by the all-season Transtaiga Road, approximately 80 kilometres east of the

community of Radisson. La Grande comprises 15,357 hectares across two exclusive exploration right

(EER) blocks, covering more than 40 kilometres of prospective Archean greenstone belt within the La

Grande Subprovince (see Figure 2). The Project is road accessible year-round and is situated close to

hydroelectric power infrastructure

Transaction Highlights

• Lux granted an option to acquire a 100% interest in the La Grande Project, a high-grade

gold project strategically situated in the James Bay region of Quebec

• Notable historical drill results (see Figure 3) include1:

- 83.8 metres @ 7.95 g/t Au (LGS97-98)

- 38.5 metres @ 4.32 g/t Au (LGS98-125)

- 56.0 metres @ 2.73 g/t Au (LGS97-83)

- 36.0 metres @ 3.37 g/t Au (LGS97-103)

- 47.4 metres @ 2.06 g/t Au (LGS01-170)

- 37.0 metres @ 1.93 g/t Au (LGS12-224)

• Historical drilling has defined broad, continuous zones of gold mineralization beginning near

surface and extending to depths of approximately 300 metres , demonstrating excellent

continuity within the mineralized system.

• Gold mineralization is structurally controlled, predominantly associated with a regional eas t-

northern shear zone that transects the property.

• The Project spans 15,357 ha across 40 km of prospective Archean greenstone belt with

historical drilling focused on only a two-kilometre portion of the trend, leaving significant upside

potential along strike.

• Excellent infrastructure with year-round road access via the Transtaiga Road and proximity

to hydroelectric power and service centres in Radisson and the La Grande-4 (LG-4)

hydroelectric generating station.

Carl Ginn, President and CEO of Lux, stated: “La Grande represents a rare opportunity to secure a

district-scale land package in a proven gold belt. With multiple mineralized zones and a fertile regional

shear system extending across the property, the Project offers significant discovery potential. Our

exploration strategy will target high-grade zones both down plunge from historical drilling and along

untested surface targets along the broader 40-kilometer gold trend. ”

La Grande Project Highlights

The La Grande Project is notable for its large number of gold occurrences and the extent of past

exploration. More than a dozen named showings have been documented, including Zone 32, Pari, Ugo,

Brèche, Vein Zone, Mico, Milan, Orezone, and Wogogoosh. These mineralized zones occur in varied

geological contexts from broad shear-hosted quartz-carbonate systems several metres wide, to narrow

laminated quartz veins hosting exceptionally high gold grades. The Zone 32 system has been the most

extensively drilled t o date and demonstrates both wide, continuous zones of gold mineralization and

discrete high-grade intercepts.

The historical results indicate significant widths of mineralization from surface to depths of

approximately 300 m, with multiple holes ending in mineralization. While the majority of historical

drilling targeted the Zone 32 system, many other showings remain largely untested by drillin g despite

strong surface results from trenching and channel sampling.

From the mid -1990s through 2015, the La Grande Project saw sustained exploration, including

geological mapping, geophysics, geochemistry, trenching, and drilling Error! Bookmark not defined. . Over this

period, 253 diamond drill holes totaling 52,472 metres were completed, primarily on the Zone 32

system, alongside 235 trenches, 14,180 rock and channel samples, and 9,700 till samples. This work

defined multiple mineralized trends, returned significant high-grade intercepts, and established a large,

well-documented exploration dataset that provides a strong foundation for modern targeting.

Geology

La Grande Project is strategically located within a major, regionally extensive shear system developed

along the contact between the La Grande Tonalite and adjacent basaltic volcanic rocks. This structural

corridor, which transects much of the Project’s 40 + kilometre strike length, is recognized as the

principal control on gold mineralization in the region.

The tonalite–basalt contact is a particularly favourable host environment, as competency contrasts

between lithologies create enhanced fracturing and permeability during deformation, allowing gold -

bearing fluids to focus along these boundaries. Within the Project area, these structures range from

discrete high-strain zones only a few metres wide to broad shear corridors up to 30 metres in thickness.

Alteration is typically dominated by sericite, carbonate, and silica, with sulphide assemblages of pyrite,

pyrrhotite, and lesser chalcopyrite and arsenopyrite1. These features are consistent with orogenic gold

systems across the Archean greenstone terranes of the Canadian Shield.

Infrastructure

The Project has excellent year-round road access via the Transtaiga Road and is within close proximity

to hydroelectric power and service centres in Radisson and LG -4. Québec’s James Bay region is

consistently ranked among the top jurisdictions globally fo r mineral exploration and development,

offering a stable regulatory framework, modern infrastructure, and strong community and logistical

support.

Next Steps

Recent work has transformed the La Grande Project’s vast historical dataset into a modern, integrated

exploration dataset. All available geological, geochemical, geophysical, and drilling data have been

digitized, spatially validated, and compiled into a single database capable of supporting advanced 3D

geological modelling. This includes high -resolution drone-based LiDAR and orthophotography, which

Lux Metals Corp. 5

provide excellent topographic and structural control, as well as recent airborne and ground geophysical

surveys that refine the definition of prospective shear zones and associated alteration systems.

This integrated database will allow Lux to rapidly generate and prioritize drill targets by combining

historical results with modern structural interpretations, shortening the timeline from acquisition to

targeted drilling and reducing duplicate early-stage work.

All reported intervals are downhole core lengths; true widths are not known at this time. The drilling

results in this news release are from work conducted by Virginia Gold Mines between 1995 and 2015.

The data is considered historical in nature and has been compiled from public sources believed to be

accurate. The Company has not verified the historical drilling results, and therefore they should not be

relied upon.

Transaction Terms

Under the terms of the Option Agreement, the Company can earn a 100% interest in the Project, subject

to underlying royalties of 4%, by completing the following:

(a) a private placement of not less than C$2,000,000 (the “Financing”); and

(b) following completion of the Financing, issuing to La Pulga the number of common shares

of the Company (“Shares”) equal to 19.9% of the then outstanding Shares following such

issuance.

In the event the Company issues a technical report in accordance with National Instrument 43-101 (“NI

43-101”) by a “qualified person” (as defined in NI 43 -101) over any or all of the Project that

demonstrates “mineral resources” (as defined in NI 43 -101) of at least 500,000 ounces of gold

equivalent mineralization, the Company will issue to La Pulga 4,000,000 Shares. In the event the

Company issues a subsequent technical report in accordance with NI 43 -101 that demonstrates

additional “mineral resources” (as defined in NI 43-101) of at least 2,000,000 ounces of gold equivalent

mineralization, the Company will issue to La Pulga an additional 4 ,000,000 Shares. Notwithstanding

the foregoing, the Company will not issue any Shares to La Pulga to the extent that, after giving effect

to such issuance, La Pulga will hold in excess of 19.99% of the issued and outstanding Shares; provided

that, once the issuance of Shares to La Pulga would not be in excess of 19.99%, the Company will issue

such Shares to La Pulga as soon as reasonably practicable.

For so long as La Pulga holds at least 5% of the issued and outstanding Shares:

(a) La Pulga will have the right to designate one nominee for election or appointment to the Board

of Directors of the Company; and

(b) if the Company desires to sell, transfer or assign its rights in the Project to a third party, La Pulga

will have a right of first refusal to acquire such rights on the same terms and conditions which

the Company offers the same to a third party.

La Pulga’s first Board nominee will be Jean-Félix Lepage, who was elected as a director of the Company

at the Company’s shareholder meeting held on September 9, 2025.

The Transaction is subject to the final acceptance of the TSX Venture Exchange (the “ TSXV”). The

Transaction is not an “arm’s-length transaction” and therefore constitutes a “reviewable transaction”
