Silver Elephant Signs Toll Milling Agreement and Ready

to Start Apuradita Silver‑Bearing Shipments in Early

August 2025

Vancouver, British Columbia, July 24, 2025 — Silver Elephant Mining Corp. (“Silver

Elephant” or the “Company”) (TSX: ELEF, OTCQB: SILEF, Frankfurt: 1P2) is pleas ed to

announce that it will commence shipping silver-bearing materials from its Apuradita Paca Project

(“ Apuradita ”) in Bolivia for toll milling. Shipments will begin the first week of August under a newly

executed toll-milling agreement with an arms-length Bolivian private company.

Pursuant to the terms of the toll ‑milling agreement dated July 7, 2025, Silver Elephant’s Bolivian

subsidiary will deliver up to 10,000  tonnes of oxide and sulphide ‑bearing materials for treatment

at a fixed toll milling fee. The agreement may be e xtended as more Apuradita resource is

developed. The toll milling facility (the “ Toll Milling Facility ”) will generate a high-grade lead -

silver and zinc - silver concentrates from the Apur dita silver materials feed. The Company will

then sell the concentrates to an international concentrate buyer under a proposed contract.

As at July 23, 2025, the Company has stockpiled app roximately 1,000 tonnes of silver-bearing

materials from Apuradita. The mineralized materials will be trucked to the Toll Milling Facility for

processing located approximately 180 km from Apurad ita. The Apuradita mining claim is

registered under Silver Elephant’s Bolivia subsidiary with the Bolivian Jurisdictional Administrative

Mining Authority. Apuradita is not within the area covered under the Mining Production Contract

between the Company and the Corporacion Minera de Bolivia (COMIBOL).

Silver Elephant maintains its near-term monthly pro duction target of 1,000 to 2,000 tonnes of

silver-mineralized materials. The Company currently forecasts approximately 10,000 tonnes of

mineralized feed over the first campaign, with further upside potential once additional resources

are developed.

To date, the main Apuradita tunnel has advanced app roximately 175 meters, and in addition,

branch drifts of  9 meters to the west and 14 meter s to the east have been developed, each

positioned to access additional mineralized zones. Logistics have been secured with a fleet of

20-ton trucks operating on a daily rotation between the mine and the Toll Milling Facility.

Metallurgical tests

Independent bench-scale metallurgical tests carried out at the Toll Milling Facility in July 2025

confirmed that conventional flotation efficiently treats materials coming from the Apuradita project:

 Sulphide samples – produced a concentrate assaying 25,552 g/t Ag and 56.6% Pb with

recoveries up to 92% silver and 87% lead based on two sulphide samples, each weighing

900 grams and grading 158 g/t Ag, 0.46% Pb, 0.4% Zn.

 Oxide samples – produced a concentrate assaying 14, 493 g/t Ag with 79.5% silver

recovery based on two oxide samples, each weighing 900 grams and grading 244 g/t Ag

and 1% Pb.

These results confirm that both the sulphide and oxide materials from Apuradita respond well to

conventional flotation techniques and can produce m arketable concentrates that meet smelter

specifications.

These tests were conducted on a laboratory scale on limited samples and are not necessarily

indicative of full-scale plant performance. Recover ies, grades, reagent consumption and

operating conditions may vary materially once comme rcial-scale processing is undertaken.

Investors are cautioned not to place undue reliance on these preliminary results. Data verification

consisted of confirming that all samples were taken from within the mineralized zones currently

being developed for toll‑milling. The Qualified Person (" QP ") checked that the sampling protocol

used was applicable for the metallurgical test work. In the QP's opinion, the test work conducted

was completed by a reputable metallurgical testing facility and used industry-standard methods.

As outlined in the news release dated July 8, 2024, sulphide mineralized materials at Apurdita will

be mined using the shrinkage stoping method. The tw o stopes are designed with approximate

dimensions of 30 meters in length x 20 meters in he ight x 4 meters in width, with a targeted

average extraction rate of 50 to 100 tonnes per day. The calculated average grade of extracted

and sorted sulphide materials is 412 g/t Ag, 1.09% Pb, and 0.38% Zn, based on diamond drill

holes at Apuradita and an internally developed mine model.

Several examples of high-grade intercepts within the Apuradita mineralized zone include:

The full drill hole assay results were previously released on SEDAR from 2015 to 2025.

The assumptions set out above are based on a resour ce estimate at Apuradita that is not a

reserve estimate. Mineral resources that are not mi neral reserves do not have demonstrated

economic viability and therefore should not be relied upon.

The Company is thankful for continued support from local communities.
