VAL-D'OR MINING ENTERS INTO MINING OPTION AGREEMENT

Val-d'Or Mining Corp. has entered into a mining option agreement with an arm's-length party, Kirkland Lake Discoveries Corp. (the optionee), dated April 25, 2025, pursuant to which the company granted an option to the optionee to acquire a 100-per-cent interest in the mineral claims comprising the Amikougami and Winnie Lake properties, located in Ontario, Canada, as described below.

In consideration of the grant of the option, the optionee shall issue to the company 1.75 million common shares in the capital of the optionee, upon receipt of approval from the TSX Venture Exchange. In addition, the optionee is required to incur expenditures on the properties in an aggregate amount of $1.2-million on or before the fourth anniversary of the receipt of exchange approval. Further, upon the optionee acquiring a 100-per-cent interest in all or a portion of the properties pursuant to exercise of the option, the optionee shall automatically be deemed to thereupon grant to the company a royalty of net smelter returns of the portion of the properties for which the option was exercised, ranging from 0.75 per cent to 2 per cent, subject to an underlying royalty of 1.25 per cent on certain claims comprising the properties in favour of Gold Royalty Corp.

The Amikougami prospect consists of 18 mining claims (approximately 388 hectares) centred in southern Bernhardt township, approximately seven kilometres northwest of Kirkland Lake, Ont. Multiple gold occurrences have been reported within the property from historical work (Ansara, Assad, Bourzk-Mondoux, Erie-Canadian and Soloman) dating back to the early 1900s and then again since the property was acquired by staking in the 1980s (Tundra Gold Mines, Pamorex Minerals and Golden Valley Mines). Numerous excavations found within the group (pits, trenches and shafts) attest to the prior work, much of which was stimulated by the early discoveries in the Kirkland Lake gold camp, following the original discoveries in the 1930s. Exploration programs more recently have included ground-based geophysical surveys (magnetic and induced polarization) and limited testing by drilling (approximately 1,000 metres in eight diamond drill holes).

The Winnie Lake prospect consists of 37 mining claims (approximately 795 hectares), centred in northwestern Teck township, about nine kilometres northwest of Kirkland Lake. Interest in this group has been focused on volcanogenic massive sulphide copper-zinc-silver-gold style mineralization since the discovery of massive sulphides in outcrop in the 1920s. Historical exploration and development work then includes a description of limited direct shipping to the Horne smelter in Rouyn-Noranda, followed by ground-based geophysical programs and limited diamond drilling (Ottawa-Teck Syndicate, Winnie Lake Mining Co., Erie Canadian Mines, Macassa Mines and Lynx Canada). Work since staking in the 1980s has included programs by Tundra Gold Mines, Pamorex Minerals and Golden Valley Mines and prospector-financed programs. Much of the more recent work was stimulated by a 1989 drill hole (TWL-89-01), which reported 22.5 metres returning 2.58 per cent Cu, 2.83 per cent Zn, 0.5 ounce per ton Ag and 0.03 oz/t Au) in the area under the original shaft occurrence. Ground-based geophysical surveys included magnetic, TDEM, HLEM, induced polarization and downhole geophysical surveys. The two properties are considered prospective for either gold or VMS style base metal mineralization. The Winnie Lake stock intrudes intermediate to mafic volcanics considered part of the Blake River group. The Blake River group has been a prolific source of VMS precious and base metal mineralization farther east (Rouyn-Noranda to Cadillac, Que.), and the Rouyn-Noranda area has been host to significant Cu-Zn-Au-Ag production for over 100 years and is generally considered to continue to be high-potential terrain for further discoveries. The VMS deposits of the Noranda camp contain a cumulative in-ground metal endowment of 2.7 million tonnes Cu, 3.0 Mt Zn, 625 t Au (approximately 20.1 million ounces) and 4,554 t Ag (approximately 146 Moz) (Monecke et al., 2017).

It has been noted by many explorationists that the Kirkland Lake camp is unique in this part of the Abitibi greenstone belt in not having produced significant VMS discoveries, which have been common in other Abitibi gold camps including Val-d'Or, Malartic, Cadillac, Rouyn-Noranda and Timmins. Much of the new program being envisaged by Kirkland Lake Discoveries is designed to test potential near the contact environment along the east side of the Winnie Lake pluton. In Kirkland Lake, seven mines have collectively produced over 24 million ounces of gold, with Timiskaming assemblage rocks, particularly those related to the Kirkland Lake Main Break, playing a significant role in this high-yielding gold region. The Kirkland Lake Main Break is a structure subparallel to the Cadillac-Larder Lake Break. The seven mines, including the Macassa, Kirkland Lake, Teck-Hughes, Lake Shore, Wright-Hargreaves, Toburn and Sylvanite mines, are all associated with this Main Break (DigiGeoATLAS,2025).

About Val-d'Or Mining Corp.

Val-d'Or is a junior natural resource issuer involved in the process of acquiring and exploring its diverse mineral property assets, most of which are situated in the Abitibi greenstone belt of Northeastern Ontario and northwestern Quebec. To complement its current property interests, the company regularly evaluates new opportunities for staking and/or acquisitions. Outside of its principal regional focus in the Abitibi greenstone belt, the company holds several other properties in Northern Quebec (Nunavik) covering different geological environments and commodities (nickel-copper-platinum group elements).

The company has expertise in the identification and generation of new projects and in early-stage exploration. The mineral commodities of interest are broad, and range from gold, copper-zinc-silver, nickel-copper-PGE to industrial and energy minerals. After the initial value creation in the 100-per-cent-owned or majority-owned properties, the company seeks option/joint venture partners with technical expertise and financial capacity to conduct more advanced exploration projects.

We seek Safe Harbor.
