Silver Elephant accelerates June sale of new silver concentrate batch

Vancouver, British Columbia--(Newsfile Corp. - June 12, 2026) - Silver Elephant Mining Corp.  (TSX: ELEF) (OTCQB: SILEF) (FSE: 1P2)  ("Silver Elephant" or the " Company")  is pleased to announce that 1,220 tonnes of silver-bearing material, with an average silver grade of 410 g/t Ag [1] , has been trucked to the toll-milling facility from the Company's Apuradita Silver Project ("Apuradita") in Bolivia. The silver-bearing material is ready for processing into a third batch of silver concentrate for expected sale in June. Underground mining operations at Apuradita continue at a steady rate.

Production has improved following the development of additional mining faces, equipment upgrades, and increased manpower. The Company is advancing additional mining faces through crosscuts and drifts to extract silver-bearing mineralized material from these new areas. The Company currently expects to produce between 400 and 600 tonnes of mineralized material per month in 2026 subject to permitting threshold, with concentrate sales planned on a quarterly basis.

As outlined in the news release dated July 8, 2024, silver-mineralized material at Apuradita is being extracted using the shrinkage stoping method. The two stopes are designed with approximate dimensions of 30 meters in length, 20 meters in height, and 4 meters in width, at an extraction rate of 20 to 40 tonnes per day. Historical drilling and internal geological interpretations indicate sulphide mineralization averaging approximately 412 g/t Ag, 1.09% Pb, and 0.38% Zn. (refer to the Company's news release dated July 8, 2024, for the underlying drill hole parameters and supporting technical data under National Instrument 43-101 standards).

As announced in the news release dated April 30, 2026, the Company is active in surface sampling situated approximately 20 meters vertically above the Apuradita tunnel system. Sampling of additional mineralized zones that are potentially amenable to open-pit mining is also ongoing. The Company appreciates the continued support from local communities.

QA/QC Silver Elephant Mining Corp. sends samples to ALS Global Laboratories in Oruro, Bolivia, for sample preparation, after which the prepared pulps are shipped to ALS Global Laboratories for analysis in Lima, Peru. Samples are analyzed using Intermediate Level Four acid digestion. Silver over-limits ("ore grade") are determined by fire assay with a gravimetric finish for precise quantification.

ALS Laboratories' sample management system meets all requirements of International Standards ISO/IEC 17025:2017 and ISO 9001:2015. All ALS geochemical hub laboratories are accredited to ISO/IEC 17025:2017 for specific analytical procedures. All samples are collected from HQ and NQ-diameter diamond drill core, which is longitudinally halved using a diamond-blade masonry saw.

One-half of the core is submitted for laboratory analysis, while the other half is preserved at the Company's secured core facility for future reference. All core is photographed and undergoes geotechnical analysis and detailed geological logging by the Company's qualified geologists prior to sampling. About Silver Elephant Mining Corp. Silver Elephant is a mineral exploration company focused on the development of its silver-lead-zinc project in Bolivia.
