Silver Elephant Starts Trucking and Toll Milling of Silver

Materials from Apuradita Paca in Bolivia

Vancouver, British Columbia, September 4, 2025 — Silver Elephant Mining Corp. (“ Silver

Elephant ” or the “ Company ”) (TSX: ELEF, OTCQB: SILEF, Frankfurt: 1P2) is ple ased to report

that trucking of silver-mineralized material from t he Company’s Apuradita Paca Project

(“ Apuradita ”) in Bolivia commenced on August 29, 2025. The mat erial mined from Apuradita is

being toll-milled at a 400-tonnes-per-day processin g plant located in Potosi, approximately 180

kilometers away (the “ Toll Milling Facility ”), to produce silver-lead-zinc concentrate for sal e to

an international concentrate buyer at spot silver price. There exists approximately 855 tonnes of

stockpiled materials to be toll milled. In addition, there is fresh mineralized materials coming from

on-going mine production. Apuradita is outside of t he 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 forecast of 1,000 to 2,000 tonnes of

silver-bearing mineralized material. The Company cu rrently projects to toll-mill approximately

10,000 tonnes of mineralized feed in the initial ca mpaign, with further upside potential as

additional mineralized zones are delineated and developed.

During Apuradita tunnel development in 2025, the Company discovered several high-grade silver-

bearing stockwork veinlet systems prior to reaching intended stoping areas. Channel sampling

conducted along the tunnel walls intercepted a 10-meter-wide of highly mineralized interval which

is not included in the current resource model, and the extent and geometry of these shoots remain

unknown. The Company plans to explore these priority targets in due course.

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 planned

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.
