SIGNATURE RESOURCES PROVIDES CLARIFICATION REGARDING PRIVATE PLACEMENT CLOSING

Signature Resources Ltd. is providing the following clarification regarding its news release dated July 15, 2026, announcing the closing of its non-brokered private placement.

The company confirms that the offering consisted of:

• 11,311,111 flow-through units issued at a price of 4.5 cents per FT unit, for gross proceeds of $509,000; and
• 2.5 million non-flow-through units issued at a price of four cents per NFT unit, for gross proceeds of $100,000 for aggregate gross proceeds of $609,000.

Each FT unit and NFT unit consisted of one common share of the company and one-half of one common share purchase warrant. Each whole warrant entitles the holder to acquire one additional common share of the company at an exercise price of eight cents for a period of 12 months from the date of issuance.

As previously disclosed, insiders of the company participated in the offering through the acquisition of 1,111,111 FT units and 2.5 million NFT units, representing approximately 26 per cent of the offering. Such participation constitutes a related-party transaction within the meaning of Multilateral Instrument 61-101 (Protection of Minority Security Holders in Special Transactions). The company relied on the exemptions from the formal valuation requirements under Section 5.5(a) of MI 61-101 and the minority shareholder approval requirements under Section 5.7(1)(a) of MI 61-101 as the fair market value of the participation by insiders did not exceed 25 per cent of the company's market capitalization.

No other material terms of the offering have changed from those disclosed in the company's news release dated July 15, 2026.

About Signature Resources Ltd.

The company is a Canadian-based advanced-stage exploration company focused on expanding the 100-per-cent-owned Lingman Lake gold deposit, located within the prolific Red Lake district in Northwestern Ontario, Canada. The Lingman Lake gold property consists of 25 single-cell and 159 multicell staked claims, four freehold fully patented claims, and 14 mineral rights patented claims totalling approximately 23,033 hectares. The property includes what has historically been referred to as the Lingman Lake gold mine, an underground substructure consisting of a 126.5-metre shaft and three levels at depths of 46 metres, 84 metres and 122 metres. There has been over 43,222 metres of drilling done on the property and four 500-pound bulk samples that averaged 19 grams per tonne of gold. The company's initial mineral resource estimate was published in the report entitled "NI 43-101 Technical Report on the Lingman Lake Property" dated May 31, 2025, prepared by Gehard Kiessling, PGeo, Farshid Ghazanfari, PGeo, Marin Drennan, PEng, Cameron Finlayson and Jeff Plate, CFA, PGeo, of Watts, Griffis and McOuat Geologic Mining Consultants. The initial published mineral resource was estimated to contained 2,145,000 tonnes of material grading 1.38 g/t Au for an estimated 95,200 ounces in the indicated category and 18,398,000 tonnes of material with an average grade of 1.14 g/t Au for an estimated 674,320 ounces in the inferred category at a cut-off grade of 0.30 g/t. The company is focused on rapidly expanding the known mineralized envelope with its 100-per-cent-owned diamond drilling rigs. In November, 2023, Wataynikaneyap Power energized a new 115-kilovolt high-tension transmission line within 40 kilometres of the historic Lingman Lake mine.
