Vancouver, British Columbia--(Newsfile Corp. - November 26, 2024) - Silver47 Exploration Corp. (TSXV: AGA) ("Silver47" or the "Company"), is pleased to announce the final results from the 2024 exploration program at the Company's wholly-owned flagship Red Mountain Project in Alaska, USA. Two infill-confirmation holes drilled at the western extent of the Dry Creek resource intersected broad zones of polymetallic sulphide mineralization with multiple high-grade massive sulphide intervals. A total of 1,039 metres of drilling was completed in 6 holes at the Dry Creek, West Tundra Flats, and Kiwi prospects combined.
Highlights
DC24-104 returned 15.24 m grading 545.5 g/t AgEq from 14.3 m depth (106 g/t silver, 0.45 g/t gold, 6.4% zinc, 2.2% lead, and 0.19% copper)
Including 6.0 m of 1,248.4 g/t AgEq from 15.9 m depth (231.1 g/t silver, 1.04 g/t gold, 14.7% zinc, 5.3% lead, and 0.46% copper)
DC24-105 returned 22.32 m of mineralization grading 601.0 g/t AgEq from 18.9 m (150.6 g/t silver, 0.82 g/t gold, 5.9% zinc, 2.6% lead, and 0.13% copper)
Including 4.25 m of 1,255.5 g/t AgEq from 20.3 m depth (238 g/t silver, 1.57 g/t gold, 14.1% zinc, 5.9% lead, and 0.17% copper)
And 2.66 m of 1,801.2 g/t AgEq from 29.1 m depth (599.4 g/t silver, 2.37 g/t gold, 14.5% zinc, 6.9% lead, and 0.64% copper)
Mr. Alex Wallis, P.Geo., Vice President of Exploration, stated: "Holes 104 and 105 confirmed infilled broad intervals of silver-gold enriched VMS style mineralization in the western portion of the Dry Creek resource, supporting the 3D modelling of historic data. Mineralization shows both stratigraphic and structural control in this zone. This new data from the 2024 drilling exploration campaign will aid in future infill drilling of high-grade zones."
Dry Creek Infill-Confirmation Drilling
Two drill holes were completed to confirm the broad, high-grade mineralization encountered by historical holes DC98-40, DC98-60, and DC99-64, which intercepted up to 40 m of semi-massive to massive sulphide in the Fosters lens of the Dry Creek deposit. The Dry Creek mineralization consists of multiple horizons of semi-massive to massive sulphides within the metavolcanics and metasediments of the Totatlanika Schist which can be traced for 4,500 m and dips steeply to the north. The Fosters and Discovery lenses of VMS mineralization make up the central 1,400 m of the Dry Creek North Horizon occurring as massive to semi-massive silver-zinc-lead-gold-copper sulphides. The lenses pinch and swell along strike and down-dip, as is typical of VMS deposits.

Mr. Gary R. Thompson, P.Geo., CEO of Silver47 Exploration Corp., commented, "We are pleased with the results from this summer's drill program at West Tundra Flats and Dry Creek, which further confirm the high-grade polymetallic mineralization and significant potential of the Red Mountain Project. These results strengthen our exploration strategy and enhance our confidence in the scale of the resource. Moving forward, our focus will be on integrating the new data into an updated geological model for planning further drilling to expand the resources along strike and down-dip. Secondary objectives for the next program will be drill testing for new discoveries like the Galleon and Horseshoe showings, as well as testing the infill potential of the 2.7 km gap between the two resource areas."
Technical Discussion on Hole DC24-104
Hole DC24-104 was planned to confirm the broad, near-surface sulphide mineralization encountered in historical hole DC98-40 in the western area of the Dry Creek deposit. The hole passes through regionally metamorphosed metasediments and metavolcanics. The top of the hole had no recovery to 14.33 m and fragmented recovery until 32.61 m with evidence of significant post-mineralization faulting through the entire hole. Mineralization was intercepted as semi-massive sulphides in metarhyolite from 15.9 m - 19.0 m and as massive sulphides from 19.0 m - 21.30 m. The 15.2 m interval from 14.3 m to 29.5 m returned a grade of 545.5 g/t AgEq, with a 6.0 m high-grade zone from 15.9 m grading 1,248.4 g/t AgEq. The semi-massive sulphides have increasing sulphide bands with depth into the massive sulphide mineralization with sparse 1 centimetre intervals of rhyolite. The sulphides are comprised of aphanitic to fine pyrite, sphalerite, galena and minor chalcopyrite. The hole is mainly composed of metarhyolite with some intervals of grey aphanitic phyllite with lesser graphitic intercalations and beds, ending in tuffaceous phyllite. The entire hole is heavily foliated with frequent intervals of fault gouge and rubbly fragments.
Technical Discussion on Hole DC24-105
Hole DC24-105 was drilled from the same pad as DC24-104, with a steeper dip to confirm continuity of high-grade mineralization between holes DC98-40 and DC98-60. Hole 105 passed through the same lithologic units as hole 104, as well as similar post-mineralization faulting. The hole is composed of mixed intervals metarhyolite and grey aphanitic phyllite with lesser graphitic intercalations and beds. The entire hole is heavily foliated. Mineralization was intercepted after a metarhyolite unit as three intervals of pyrite-sphalerite-galena and minor chalcopyrite massive sulphide interspaced with felsic phyllite: 20.3 m - 21.1 m, 22.3 m - 27.8 m, and 29.1 m - 32.6 m. These high-grade lenses are encapsulated by a 22.3 m interval returning a grade of 601 g/t AgEq, including 2.66 m of 599.4 g/t silver, 2.37 g/t gold, 14.5% zinc, 6.9% lead, and 0.64% copper.

Galleon Silver Target
The Galleon Target is a high-priority silver target, with historical samples returning up to 1,265 g/t silver, 2.1 g/t gold, and 5% combined zinc and lead. The semi-massive sulphide is hosted in a metarhyolite of the Mystic Creek Member, on the north limb of the Bonnifield East Syncline, a similar depositional setting to the Dry Creek mineralization. Historic work includes, mapping, trenching, 3.9 km of IP survey, and several short drill holes completed in 1981 with a Winky drill. The 1981 drilling failed to intercept mineralization, but frequently had zero core recovery for many intervals.
In 2024, Silver47 collected 101 soil samples for analysis by XRF in the field, and 8 rock grab samples. The soil samples identified several areas of anomalous zinc and lead in the soil/talus fines around the Galleon Target and three of the rock samples returned significant polymetallic grades. The location of historical high-grade samples was inaccessible due to significant degradation of the trench workings. However, a sub-crop rock sample taken from a historical trench/drill pad returned 132 g/t silver, 1.26 g/t gold, and 1.9% combined zinc and lead. Three samples also returned anomalous values for critical minerals antimony and rubidium.
Horseshoe SEDEX Target
The Horseshoe Target was identified in 2020 with rock and soil sampling covering approximately 200 m of gossanous exposure. Located within the Keevy Peak Formation, the host rocks exhibit more clastic composition than the Totatlanika Schist, suggesting potential for sedimentary exhalative (SEDEX) mineralization. Historic samples have returned up to 37.9 g/t silver, 3.81 g/t gold, and 6.8% combined zinc and lead.
In 2024, Silver47 collected 94 soil samples for XRF analysis, and six rock grab samples. Elevated zinc and lead concentrations were detected throughout the soil grid, with higher values coinciding with the gossan zone. Three rock samples returned values maintaining Horseshoe as a high-priority exploration target, with the best sample grading 36.6 g/t silver, 0.78 g/t gold, 4.4 combined zinc and lead, and 147.5 ppm antimony. Detail outcrop structural mapping, with tighter-spaced soil-rock geochemistry is planned to further develop Horseshoe into a drill-ready target.
Kiwi Target Drilling and Geochemical Sampling
The Kiwi Target was identified by the previous operators from surface boulders of high-grade copper-silver rock samples, including a high of 16.2% copper and 316 g/t silver. Two historical drill holes KW21-01 and KW21-02 were drilled to test the potential source of this mineralization. Neither historical hole intercepted sulphide mineralization comparable to the surface samples. A 2021 fixed loop electromagnetic survey was completed over the target, with the results showing a strong conductive anomaly east of holes KW21-01 and KW21-02. Hole KW24-03 was drilled to a depth of 283 m to test this conductive feature. While narrow intervals of sulphide mineralization including chalcopyrite were encountered in the hole, no significant results were returned.
Prior to the 2024 drilling, Silver47's geologists prospected down the western slope of the Kiwi zone to confirm the historic rock samples. Of the seven rock samples collected, three returned high-grade copper, silver, and gold values, including 2 samples over 10% copper and silver values of 165 g/t and 218 g/t. Extensive follow-up sampling and structural mapping is needed to guide future drilling at the Kiwi Target. However, given the high number of targets on the Red Mountain Project and the lackluster drill results here, the Kiwi Target has been reduced to a lower priority ranking.
About the Red Mountain VMS-SEDEX Project - Alaska, USA
Silver47's flagship Red Mountain property covers 633 square kilometres of Alaska State-managed land 100 km south of Fairbanks, Alaska. The project is well situated for infrastructure, 30 km east of the community of Healy which has power, rail and state highway access to Alaska Route 3, providing a valuable connection to Anchorage and tide water. The Company has an approved permit to conduct advanced exploration, including drilling, across the property.
Red Mountain hosts a NI 43-101 inferred mineral resource estimate of 15.6 Mt at 7% ZnEq for 1 Mt of ZnEq or 335.7 g/t AgEq for 168.6 Moz AgEq at the Dry Creek (DC) and West Tundra Flats (WTF) resource areas as combined open pit and underground. DC and WTF are the two most advanced mineralized zones at Red Mountain, with at least 20 additional mineralized prospects discovered on the property to date over the 60 km of highly prospective geology.
For more information, see the Red Mountain NI 43-101 technical report titled "Technical Report on the Red Mountain VMS Property, Bonnifield Mining District, Alaska, USA" dated January 12, 2024, prepared by Apex Geoscience Ltd., which can be found on the Company's website https://silver47.ca/ and SEDAR+.
Quality Assurance and Quality Control
Quality assurance and quality control (QAQC) protocols for drill core sampling at the Red Mountain Project followed industry standard practices. Core samples were typically taken at 1.0m intervals in mineralized zones, and 3.0m intervals outside of mineralized zones. Sample lengths were adjusted as necessary so as not to cross lithologic and mineralogic boundaries. QAQC check samples were inserted into the sample stream with one blank, one duplicate (coarse), and one certified reference material (CRM) occurring within every 20 samples. Drill core was cut in half, bagged, sealed and delivered directly to ALS Minerals Fairbanks, Alaska for transport to the ALS Minerals Laboratories labs in North Vancouver, British Columbia. ALS Minerals Laboratories are registered to ISO 9001:2008 and ISO 17025 accreditations for laboratory procedures. Core samples were analyzed at ALS Laboratory facilities in North Vancouver using four-acid digestion with an ICP-MS finish. Gold analysis was by fire assay with atomic absorption finish, or gravimetric finish for over-limit samples. Over-limits for silver, zinc, copper, and lead were analyzed using Ore Grade four-acid digestion. The standards, certified reference materials, were acquired from CDN Resource Laboratories Ltd. of Langley, British Columbia and selected to represent expected mineralization.
