Silver47 Exploration Launches Drilling to

Expand Silver-Rich VMS Deposits at Red

Mountain, Alaska

Fully-Funded 4,000 Meter Program with Planned Upsize to

Boost High-Grade Silver and Critical Minerals

Vancouver, British Columbia--(Newsfile Corp. - June 18, 2025) - Silver47 Exploration Corp.

(TSXV:

AGA) (OTCQB: AAGAF)

("

Silver47

" or the "

Company

") is pleased to announce the commencement of

a fully-funded drill program at Silver47's wholly-owned Red Mountain VMS Project in south-central

Alaska.

Highlights

Drilling Commences at Red Mountain

: A core drilling rig is now fully operational at the Red

Mountain project in Alaska, actively advancing the first hole of Silver47's 2025 summer exploration

program.

Targeting High-Impact Resource Growth

: The program focuses on expanding the inferred

168.6 million silver equivalent ounce resource (336 g/t AgEq*) at Dry Creek and West Tundra Flats

(see Table 1), where previous drilling by Silver47 and prior operators indicates significant

expansion potential.

High-Grade Precious Metals Potential:

The 2025 program targets untested areas near

historical high-grade intercepts, prioritizing areas richer in silver and gold to enhance Red

Mountain's resource base.

Strategic Critical Minerals Focus

: Red Mountain hosts five critical minerals scarce in the U.S.,

including zinc, copper, tin, antimony and gallium, which will be evaluated during this program to

support domestic supply chain security.

Upsized Program on the Horizon

: Closing of Summa Silver's oversubscribed $6.9 million

subscription receipt financing was completed on June 17

th

, paving the way for a substantial

expansion of the current drilling campaign when the Silver47 and Summa Silver merger is

complete.

Gary Thompson, CEO of Silver47, stated:

"

We are excited to kick off a significant drill program at

our Red Mountain silver-gold-rich VMS project with a view to expanding the resource base and

making new discoveries. The results from previous drill holes, including DC24-106, WT24-33 and

DC18-77, demonstrate the robust nature of the Bonnifield district, where Red Mountain is located, and

we are eager to build on these successes. This year is shaping up to be transformational for the

Company with a full season of drilling and the pending merger with Summa Silver

."

.

The 2024 Red Mountain MRE 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 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.

9

.

Recoveries are 90% Zn, 75% Pb, 70% Cu, 70% Ag, and 80% Au.

10

.

ZnEQ (%) = [Zn (%) x 1] + [Pb (%) x 0.6364] + [Cu (%) x 2.4889] + [Ag (ppm) x 0.0209] + [Au (ppm) x 0.1923]

11

.

AgEQ (ppm) = [Zn (%) x 47.81] + [Pb (%) x 30.43] + [Cu (%) x 119] + [Ag (ppm) x 1] + [Au (ppm) x 91.93]

12

.

Open-pit resource economic assumptions are US$3/tonne for mining mineralized and waste material, US$19/tonne for processing, and

48° pit slopes.

13

.

Underground resource economic assumptions are US$50/tonne for mining mineralized and waste material and US$19/tonne for

processing.

14

.

Open-pit resources comprise blocks constrained by the pit shell resulting from the pseudoflow optimization using the open-pit economic

assumptions.

15

.

Underground resources comprise blocks below the open-pit shell that form minable shapes. They must be contained in domains of a

minimum width of 1.5 m at Dry Creek or 3 m height at West Tundra Flats. Resources not meeting these size criteria are included if, once

diluted to the required size, maintain a grade above the cutoff.

16

.

Global AgEq calculated using component metal grades: 3.41% Zn, 1.39% Pb, 0.17% Cu, 71.4 g/t Ag, 0.43 g/t Au.

Red Mountain Project Overview

Red Mountain, situated in south-central Alaska, is a high-grade volcanogenic massive sulfide (VMS)

deposit wholly owned by Silver47 Exploration Corp. Hosted within the Devonian to Mississippian-aged

Totatlanika Schist, the deposit comprises submarine volcanic and volcaniclastic rocks, primarily felsic to

intermediate tuffs and flows, ideal for VMS mineralization. The project hosts an inferred resource of

168.6 million silver equivalent ounces at 336 g/t AgEq across the Dry Creek and West Tundra Flats

deposits, with high-grade silver, gold, zinc, lead, and copper as reported in the NI 43-101 Technical

Report dated January 12, 2024. Of particular importance, both Dry Creek and West Tundra Flats remain

open to expansion. Beyond precious and base metals, Red Mountain contains critical minerals-

antimony, gallium, zinc, copper, and tin-scarce in the U.S., supporting national supply chain security

goals.

The broader Red Mountain property, spanning over 630 square kilometers, remains substantially

underexplored. Airborne magnetic and electromagnetic surveys have identified multiple untested targets

within the Totatlanika Schist's favorable stratigraphy. These targets, coupled with coincident high-grade

mineralized rock samples and anomalous soil geochemistry, suggest strong potential for discovering

additional VMS and sedimentary exhalative deposits across the property, positioning Red Mountain as

a district-scale opportunity.
