NEVADA SUNRISE ANNOUNCES AGREEMENT TO PURCHASE A 100% INTEREST IN THE PAST-PRODUCING GRIFFON GOLD MINE PROJECT, NEVADA

Nevada Sunrise Metals Corp. has signed a mining lease purchase agreement with an arm's-length vendor for the Griffon gold mine project located approximately 50 kilometres (33 miles) southwest of Ely, Nev. The project consists of 89 unpatented mineral claims totalling approximately 1,780 acres. Griffon is situated at the southern extension of the fertile Battle Mountain-Eureka gold trend in east-central Nevada, which is host to both past-producing and operating gold mines, and a number of significant gold deposits. Gold was mined at Griffon in two open pits from 1998 to 1999 and was reported to have produced 62,661 ounces of oxide gold until its premature closure (source: Nevada Division of Minerals, "Major Mines of Nevada," published 1998 and 1999).

"The acquisition of Griffon represents a golden opportunity for Nevada Sunrise," said Warren Stanyer, president and chief executive officer of the company. "This property has been underexplored for almost three decades and offers good potential to host additional gold resources. As we enter an era of record-high gold prices, Nevada Sunrise intends to apply new ideas and modern exploration technologies at Griffon to capitalize on the renewed interest in gold in Nevada, which is recognized as one of the most mining-friendly jurisdictions in the world."

About Griffon

Griffon lies within a 60-kilometre (40-mile) section of the Battle Mountain-Eureka trend that hosts the following gold mines and deposits:

• Pan mine: operated by Calibre Mining Corp., which hosts measured and indicated resources of 358,900 ounces gold and inferred resources of 42,000 oz gold, and reported as producing 35,267 oz gold in 2024;
• Gold Rock (formerly Easy Junior): operated by Calibre Mining, which hosts measured and indicated resources of 370,700 oz gold and inferred resources of 58,100 oz gold;
• Mount Hamilton: the subject of a transaction with an emerging public company, Bendito Resources Inc., which hosts proven and probable mineral reserves of 545,000 oz gold and 4,459,600 oz silver contained within measured and indicated resources of 727,000 oz gold and 6,569,000 oz silver, and inferred resources of 119,000 oz gold and 1,153,000 oz silver;
• Green Springs: owned by Orla Mining Ltd. and currently under option to Centerra Gold Inc.; historical production at Green Springs of 63,000 oz of gold was reported from 1988 to 1991 under USMX Inc.'s heap leach operation;
• Lookout Mountain: operated by Timberline Resources Corp., a fully owned subsidiary of McEwen Mining Inc., which hosts measured and indicated resources of 423,000 oz gold, and inferred resources of 84,000 oz gold; historical production of 17,700 oz gold was reported in 1987.

History of exploration

Griffon is located in a mining district that received little historical exploration or mining activity until the late 1980s when the area was explored by Shell Oil and Placer Dome U.S. Inc. Subsequent exploration by Billiton Minerals identified the Discovery Ridge deposit, and, following its discovery in 1988, several mining companies alternately controlled Griffon prior to the commencement of gold production.

Definition drilling by Alta Gold Co. in the early to mid-1990s resulted in the discovery of the nearby Hammer Ridge deposit. A total of 214 drill holes totalling 62,768 feet (19,137 metres) were drilled to delineate both deposits at the project, and a mine plan was generated and approved in 1997.

Alta reported production of 62,661 ounces of gold from the two deposits between 1998 and 1999. A proposed expansion of the Hammer Ridge pit was being pursued by Alta when it was forced to declare bankruptcy in 1999 after suffering unsustainable losses incurred during the start-up of its Olinghouse mine, near Reno, Nev.

After gold production ended in 1999, Griffon received no further exploration activity until 2020, when Fremont Gold Ltd. drilled nine holes totalling 2,275 metres (7,462 feet) at the project. Two drill holes showed significant gold values (source: Fremont Gold news release dated July 21, 2020):

• Hole GF20-03 intersected 1.05 grams per tonne gold over 50.3 metres beginning at 29.0-metre depth, including 1.57 g/t gold over 7.5 metres.
• Hole GF-20-2 intersected 0.30 g/t gold over 30.0 metres beginning at 15.0-metre depth, including 0.71 g/t gold over 8.0 metres.

Griffon is described in historical geological reports available to the company as a Carlin-type gold deposit model in a very structurally disturbed area that makes the geological controls of potentially mineralized zones difficult to predict. The sedimentary units present such as the Pilot shale, Chainman shale and the Joana limestone are subject to a number of interpreted fault types with numerous folds, including low-angle thrust, low-angle normal, high-angle normal and high-angle strike-slip faults that have yet to be comprehensively mapped and understood.

Nevada Sunrise has received a digital database containing all of the 1990s drill holes and intends to reprocess and computer model the drilling data for a better understanding of the stratigraphies that may host gold mineralization outside of the two historical pits. In conjunction with computer modelling, the company believes that the application of modern ground geophysics and leading-edge soil geochemical surveys could assist in determining new target areas at the project. The only application of modern geophysics at Griffon consisted of a gravity survey completed in 2012 that assisted in mapping many of the complex structures observed in the results. Nevada Sunrise is currently soliciting a bid for an induced polarization/resistivity survey for integration with the 2012 gravity data, and plans to carry out conventional and soil gas hydrocarbon soil surveys over the interpreted structures to optimize new drill targets at Griffon.

Details of the Griffon mining lease purchase agreement terms

In February, 2025, Nevada Sunrise entered into a mining lease for the project, which began its term upon execution of the agreement and remains in effect at the company's option until Feb. 13, 2032. The company retains the right to purchase a 100-per-cent interest in Griffon, subject to a 2.0-per-cent net smelter return royalty with certain buydown provisions, in consideration for the cash payments to the vendors and minimum exploration expenditures as described in the table below (all dollar amounts listed are in U.S. dollars).

Nevada Sunrise retains the right to accelerate the timing of cash payments to the vendors at its discretion. The vendors have granted the exclusive and irrevocable right and option for the company to purchase 100 per cent of Griffon, subject to the 2.0-per-cent NSR, at any time during the term of the lease by paying an amount equal to the aggregate value of any remaining cash payments plus the amount of the greater value of (i) $750,000; and (ii) 285 ounces gold.

At any time during the term of the lease, if minimum annual exploration expenditures are exceeded in any year, which include property maintenance costs and any other costs related to exploration and development of the project, the excess expenditures will be credited to a succeeding year.
