Vancouver, British Columbia--(Newsfile Corp. - June 12, 2026) - Silver47 Exploration (TSXV: AGA) (OTCQX: AAGAF) ("Silver47" or the "Company") is pleased to announce that its fully funded, 2026 summer drill program has commenced across the high-grade silver and critical minerals Red Mountain Project, Alaska (the "Red Mountain Project").

Key Highlights:

• Drilling Underway: A core drilling rig is now fully operational at Red Mountain, actively advancing the first hole of the 2026 summer exploration program. All three drill rigs are expected to be active at the end of the month.

• Targeting Resource Growth at Dry Creek: The program will focus on expanding the inferred 168.6 million silver equivalent ounce resource (336 g/t AgEq*), while systematically increasing tonnage at the Dry Creek deposit.

• Discovery Drilling at District-Scale Targets: Drilling will test numerous largely undrilled polymetallic massive sulfide occurrences across the 60 km prospective trend where expert multi-faceted data analysis indicates the highest degree of prospectivity.

• U.S. Silver & Critical Mineral Focus: The summer drill program at Red Mountain will target U.S. silver and critical minerals, positioning the project as a strategic American source of high-demand materials.

• Fully Funded: The Company holds approximately C$48 million in working capital, providing a strong financial position to execute the planned program.

*Notes: g/t=grams per tonne; AgEq=silver equivalent; ZnEq=zinc equivalent; m=metres; Ag=silver; ‎Au=gold; Cu=copper; Zn=zinc; Pb=lead; 1ppm=1 g/t. Equivalencies are calculated using ratios with metal prices of US$2,750/tonne Zn, US$2,100/tonne Pb, US$8,880/tonne Cu, US$1,850/oz Au, and US$23/oz Ag and metal recoveries are based on metallurgical work returned of 90% Zn, 75% Pb, 70% Cu, 70% Ag, and 80% Au. Silver Equivalent (AgEq g/t) = [Zn (%) x 47.81] + [Pb (%) x 30.43] + [Cu (%) x 119] + [Ag (g/t) x 1] + [Au (g/t) x 91.93]

Galen McNamara, CEO, stated: "With three rigs and 10,000 metres of drilling planned, this marks the largest exploration program ever undertaken at Red Mountain. The program is designed to both expand the existing resource and systematically evaluate several high-priority targets that have seen limited or no previous drilling. Red Mountain continues to demonstrate the characteristics of a large-scale, silver-rich mineralizing system, and we believe this campaign has the potential to significantly enhance the project's value through resource growth and the discovery of additional massive sulphide mineralization along the 60-kilometre prospective trend."

The Drill Program

The 2026 exploration drill program at the Red Mountain Project, 60 miles south of Fairbanks, Alaska will consist of at least 10,000 meters of core drilling focused on deposit expansion and discovery (see June 4^th, 2026 news release).

Priority volcanogenic massive sulfide (VMS) exploration targets at Red Mountain are dispersed across the highly prospective Bonnifield mining district which comprises at least 60 km of stratigraphy considered favorable for VMS mineralization.

Drill program objectives include:

• Further delineation and expansion of the Dry Creek deposit (inferred mineral resource of 11.6 million tonnes at 279.4 g/t AgEq, totaling 104.0 million silver equivalent ounces*, Table 1) through a series of infill and step-out holes down-dip, approximately 3,000 m, designed to investigate the orientation and structural controls on higher-grade VMS mineralization (e.g., 22.3 m at 601 g/t AgEq* (150.6 g/t Ag, 0.82 g/t Au, 5.86% Zn, 2.60% Pb, 0.13% Cu) in DC24-105). Drilling will also evaluate the down-dip and strike extents of these higher-grade zones where mineralization remains open.

• New discovery by evaluating the high-grade mineralization potential of numerous VMS targets identified across the Dry Creek Syncline and Last Chance corridor (Figure 1). Of the known exploration targets (see August 13, 2025 and December 30, 2025 news releases), only eleven targets have been drill tested, five of those with less than three holes each¹. Based on these limited historical drill data together with results from recent project-wide geochemical sampling (rocks, soil and talus-fines) numerous high-priority targets have been identified (e.g., Sheep Creek, Hunter, Glacier, FOMO and WTF E).

• Target refinement and new target identification through project-wide exploration activities including geological mapping, grid-based soil geochemical surveys and project-wide heli-borne hyperspectral surveying.

1. The 2024 Red Mountain Mineral Resource Estimate was estimated and classified in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") "Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines" dated November 29, 2019, and the CIM "Definition Standards for Mineral Resources and Mineral Reserves" dated May 10, 2014.
2. Mr. Warren Black, M.Sc., P.Geo. of APEX Geoscience Ltd., a QP as defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101"), is responsible for completing the 2024 Mineral Resource Estimate, effective January 12, 2024.
3. Mineral resources that are not mineral reserves have not demonstrated economic viability. No mineral reserves have been calculated for Red Mountain. There is no guarantee that any part of the mineral resources discussed herein will be converted to a mineral reserve in the future.
4. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, market, or other relevant factors.
5. The quantity and grade of reported Inferred Resources is uncertain, and there has not been sufficient work to define the Inferred Mineral Resource as an Indicated or Measured Mineral Resource. It is reasonably expected that most of the Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
6. All figures are rounded to reflect the relative accuracy of the estimates. Totals may not sum due to rounding. Reported grades are undiluted.
7. A standard density of 2.94 g/cm³ is assumed for mineralized material and waste rock. Overburden density is set at 1.8 g/cm³. For mineralized material blocks with iron assays close enough to estimate an iron value for the block, density is calculated using the formula: density (g/cm³) = 0.0553 * Fe (%) + 2.5426.
8. Metal prices are US$2,750/tonne Zn, US$2,100/tonne Pb, US$8,880/tonne Cu, US$1,850/oz Au, and US$23/oz Ag.
