ROKMASTER PROVIDES UPDATE ON NECHAKO PROJECT AND ANNOUNCES FINANCING

Rokmaster Resources Corp. has provided an update on the Mystery and Fox-Coconut properties within the Nechako project.

The Nechako project is located in west-central British Columbia within the prolific Stikine terrane with several past-producing deposits and advanced development projects in the region. Rokmaster has options to acquire up to a 100-per-cent interest on the three road-accessible properties (Mystery, Fox-Coconut and Hanson), which, when combined, total 27,178 hectares (271 square kilometres). Each property in the Nechako project features positive historical exploration work which Rokmaster is assessing to develop compelling exploration drilling targets for significant copper-plus-or-minus-molybdenum-plus-or-minus-gold mineralization in this favourable district.

The company is pleased to announce that it recently received a three-year exploration permit on the Mystery property that allows for 12 drill sites and six helicopter pads, which are necessary to fully test the multiple targets on the Mystery property. The Mystery property features several targets for porphyry copper-plus-or-minus-molybdenum-plus-or-minus-gold mineralization in the intensely argillic altered central core of the property as well as a large property size in suitable geology to encompass additional early-stage targets.

So far in 2025, fieldwork on the Mystery property includes detailed mapping and prospecting, which collected detailed channel and chip sampling on an approximately 200-metre-wide exposure of potassic-altered andesite hosting extensive pyrite-chalcopyrite veinlets in the B2 zone. A 190-line-kilometre magnetic survey further resolved the Ford anomaly, which is a 1.0-kilometre-diameter circular magnetic anomaly at the northern end of the historic Ford claims, which were unavailable for most of the previous operators. The Ford anomaly occurs near the northern end of the large area of sericite- and pyrite-altered rhyolite and hosts a large strong copper-gold anomaly coincident with the margins of the magnetic feature. The area is also near the southern contact of a monzonite stock that belongs to the fertile Late Cretaceous Bulkley suite associated with porphyry copper-molybdenum-gold-silver mineralization at the nearby Huckleberry, Ox and Seel deposits.

The company completed trenching in the eastern portion of the Fox-Coconut property in 2025, where high-grade gold and silver mineralization occurs in the recently discovered NW structure. This linear zone of subcropping boxwork quartz-limonite veining is approximately 300 metres in length. Grab samples collected in 20192 returned up to 33.4 grams per tonne gold and 6,273 grams per tonne silver. This area was the focus of the 2025 trenching where 68 channel and chip samples were collected across four trenches. The samples are currently being processed, and the company hopes to report results soon.

John Mirko, president and chief executive officer, commented: "Fieldwork on the Nechako project has been progressing smoothly and efficiently during the 2025 field season. The positive work on the Mystery property is further polishing robust drill targets for significant porphyry copper-plus-or-minus-molybdenum-plus-or-minus-gold mineralization next door to the exciting work taking place on the Rip and Poplar projects. The exploration programs conducted on the Fox-Coconut property will further refine the targets for road-accessible high-grade gold and silver mineralization close to the newly commissioned Blackwater mine. We are excited to receive assays from the lab, which will guide our strategy going forward."

Financing

The company also announces that it intends to raise on a non-brokered financing basis up to $800,000 in flow-through financing that will consist of up to 20 million flow-through units priced at four cents per flow-through unit. Each flow-through unit will consist of one flow-through common share plus one-half non-flow-through share purchase warrant. Each non-flow-through warrant is exercisable to purchase one additional non-flow-through common share of the company at six cents for a period of two years from the date of closing.

The flow-through shares will qualify as flow-through shares (within the meaning of Subsection 66(15) of the Income Tax Act (Canada). The gross proceeds raised from the issuance of the flow-through shares will be used by the company to incur Canadian exploration expenses (within the meaning of the tax act). The company reserves the right to accept additional funds or increase the flow-through financing, subject to regulatory approval, should the flow-through financing be oversubscribed.

The company may pay finders' fees to certain third parties of up to 7 per cent in cash and up to 7 per cent in compensation warrants in connection with the sale of flow-through units to arm's-length subscribers. Each compensation warrant will entitle the holder to purchase one additional common share of the company at five cents for a period of two years from the date of closing.

Closing of the flow-through financing and the payment and/or issuance of the finders' fees are subject to TSX Venture Exchange approval and all securities issued pursuant to the flow-through financing and finders' fees will be subject to a four-month-and-one-day hold period from the closing date.

The technical information in this news release has been prepared in accordance with Canadian regulatory requirements as set out in National Instrument 43-101 and reviewed and approved by Eric Titley, PGeo, who is independent of Rokmaster and who acts as Rokmaster's qualified person.
