Vancouver, British Columbia--(Newsfile Corp. - October 14, 2026) - Silver Elephant Mining Corp. (TSX: ELEF) (OTCQB: SILEF) (FSE: 1P2) ("Silver Elephant" or the "Company") is pleased to announce that it has engaged Mercator Geological Services Limited ("Mercator") of Dartmouth, Nova Scotia to prepare an independent technical report on the Robinson-Lasher zinc-germanium-gallium project (the "Robinson-Lasher Project" or the "Project") in Livingston County, Kentucky. The Robinson-Lasher Project is primarily a zinc deposit, with germanium and gallium occurring as potential by-product credits hosted within the zinc mineralized zone. The report will be prepared in accordance with National Instrument 43-101 ("NI 43-101").
The engagement is being led by Michael Cullen, P.Geo., Chief Geologist of Mercator, a professional geologist with over 40 years of mineral exploration experience, that includes previous work in the Illinois-Kentucky Fluorspar District (the "IKFD"). Mr. Cullen visited Robinson-Lasher Project in August 2026 as part of the engagement.
Following the August 2026 site visit, Mercator anticipates completing the NI 43-101 technical report on the Project by the end of October 2026. The report is intended to consolidate and independently assess the Project's historical zinc, germanium, and gallium potential, but is not expected to include a current mineral resource estimate.
A core sampling and assay program has also commenced on the archived drill core from the Project's 2008 drilling program. The core sampling and assay program is designed to verify and extend the historical germanium and gallium results announced by the Company on July 6, 2026, and represents the first systematic multi-element sampling of the preserved Robinson-Lasher core. Germanium price is currently $8,597/kg ($267/oz) according to strategicmetalsinvest.com.
Program details are set out in the Verification and Sampling Program section below.
About the Robinson-Lasher Project
The Robinson-Lasher Project comprises approximately 1,524 acres of mineral rights in Livingston County, Kentucky, and is primarily a zinc project. Zinc and fluorspar occur as bedded and replacement-style mineralized zones in Mississippian-age carbonate rocks along the Robinson Fault structure. This setting is a classic Mississippi Valley-type ("MVT"), the same as the Tennessee zinc mines that supplied concentrate to the Clarksville, Tennessee zinc smelter for more than 50 years. The Project has been drill tested with 232 historic drill holes, over an interpreted mineralized strike length of approximately 4000 feet[1].
Historical high-grade zinc intervals from the 2008 confirmation drill program include 81.4 feet (24.8 meters) grading approximately 11.2% zinc (hole DXHR-01) and 16.0 feet (4.9 meters) grading approximately 13.4% zinc (hole DXHR-03). Germanium and gallium were analyzed on samples from these two holes, returning germanium of up to 350 g/t and gallium of up to 20 g/t within the zinc-mineralized (sphalerite) zones, with the highest germanium value in each hole associated with the hole's highest-grade zinc interval. Core intervals were assayed at ACME Analytical Laboratories (Vancouver, B.C.). Base metals were determined by four-acid digestion with an ICP-ES finish, and gallium and germanium were determined on samples from two of the holes - DXHR-01 and DXHR-03. Holes DXHR-02 and DXHL-01 were assayed for zinc and fluorspar but were not analyzed for germanium or gallium.[2]
Germanium and gallium do not occur as discrete minerals at the Project; they are interpreted to substitute within the crystal lattice of sphalerite (zinc sulfide) and broadly correlate with the zinc mineralized zone. If this spatial relationship is confirmed, germanium and gallium could be recoverable as by-product credits during conventional zinc-concentrate production. The full sample-by-sample results for holes DXHR-01 and DXHR-03 are set out in Table 1, and drill-hole details are set out in Table 2.[3]

Notes: Depths are downhole; holes are vertical (-90°), so downhole intervals approximate true thickness. 1 ppm = 1 g/t; 1 foot = 0.3048 m. "nil" = below detection; "NA" = not analyzed for that element. For DXHR-01, samples 101-103 and 119 bracket the mineralized zone but were not analyzed for Ga/Ge. Composites are thickness-weighted averages over the indicated samples. Source: 2008 Report; ACME certificates VAN08004249 / VAN08005302 / VAN08005639.

The Project also hosts an existing 1,270-foot production decline reaching approximately 240 feet of vertical depth, together with a ventilation shaft; underground access is subject to rehabilitation. The Company cautions that the historical germanium and gallium analyses were performed on a limited number of samples from two of the four holes drilled in 2008 and are insufficient, on their own, to characterize the distribution, continuity or grade of germanium or gallium across the Project.
Verification and Sampling Program
The core from the 2008 confirmation drilling program is archived at the Earth Analysis Research Library in Lexington, Kentucky. This facility is the core and well sample repository operated by the Kentucky Geological Survey, a research center of the University of Kentucky. All four core holes completed during the 2008 program are preserved in the collection. The Company's technical team examined the core at the repository in August 2026 and confirmed that the mineralized intervals remain intact and suitable for sampling.
The sampling program covers 151.9 feet of core across all four preserved holes, focused on the zinc-mineralized intervals logged along the Robinson Fault structure, as set out in Table 3. Two complementary methods are being applied over the same intervals:
Portable X-ray fluorescence. Non-destructive readings are being taken at four-inch spacing down each mineralized interval. The readings will produce a semi-continuous, high-resolution multielement profile through each interval, allowing mineralized boundaries to be defined at a resolution far finer than the historical sample intervals.
Dremel-cut samples for laboratory analysis. Samples are being cut at five-foot intervals using a precision rotary tool, a method selected specifically to recover analytically sufficient material while preserving the archive core. Each sample will be submitted to the University of Kentucky for multi-element determination including zinc, germanium, gallium, silver, lead and fluorine.
Table 3 - Sampling program by drill hole
| Drill hole | Interval sampled (ft) | Length (ft) |
| DXHR-01 | 545.6-645.0 | 99.4 |
| DXHR-02 | 504.0-521.0 | 17.0 |
| DXHR-03 | 626.0-652.0 | 26.0 |
| DXHL-01 | 217.0-226.5 | 9.5 |
| Total | 151.9 |
As noted above, holes DXHR-02 and DXHL-01 were not analyzed for germanium or gallium during the 2008 program, and samples from these holes are therefore being drawn from core for which no germanium or gallium data exists. Samples from holes DXHR-01 and DXHR-03 are being taken to verify the historical results set out in Table 1 under modern analytical and quality-control protocols.
Sampling is being conducted in accordance with the sampling policies of the Kentucky Geological Survey, which require that sufficient archive material be retained in each core box for future examination. Analytical results generated from repository material are provided to the Kentucky Geological Survey and become part of the public record of the collection.
Analytical Protocol and Quality Control
All samples will be prepared and analyzed at the University of Kentucky Department of Plant and Soil Sciences. Zinc, germanium, and gallium will be determined by inductively coupled plasma mass spectrometry, which provides the low detection limits and freedom from spectral interference required for accurate determination of germanium in a high-zinc matrix.
The University of Kentucky Department of Plant and Soil Sciences uses a full quality assurance and quality control protocol. This includes Matrix-matched external standards that are prepared using certified reference materials (Inorganic Ventures, Blacksburg, VA, USA). An internal standard (Y) is added at 10 µg/L for all samples and standards. Quality control procedures included initial calibration verification (ICV), continuing calibration verification (CCV), initial blank verification (IBV), continuing blank verification (CBV), analysis of digestion replicates, analysis of dilution replicates, determination of spike recovery, analysis of standard reference materials (SRMs) if available, and analysis of digestion blanks with each analytical batch. An octopole reaction system pressurized with He or H2 to suppress polyatomic interferences as appropriate. REE++ interferences are corrected for.
Next Steps
Sampling is expected to be completed during the fourth quarter of 2026, with laboratory results anticipated approximately two to three weeks following submission. Subject to results, the Company intends to advance the phased program outlined on July 6, 2026, including compilation and validation of the historical drill database, confirmation drilling on the Robinson structure with dedicated germanium and gallium sampling, and preliminary metallurgical testwork to assess germanium and gallium deportment to zinc concentrate.
Readers are cautioned that no metallurgical testwork, processing arrangement, mineral resource estimate or economic assessment has been completed on the Robinson-Lasher Project, and there is no certainty that germanium or gallium can be economically recovered.
Historical Results Disclosure
The resource estimates and drill results disclosed in this news release are "historical estimates" and "historical results" as defined under National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101"). The historical estimates were prepared prior to the implementation of current CIM Definition Standards, and the key assumptions, parameters and methods used to prepare them are not fully available to the Company. The historical estimates have not been verified or validated by the Company as current mineral resources or mineral reserves. A qualified person, as defined under NI 43-101, has not done sufficient work to classify the historical estimates as current mineral resources or mineral reserves, and the Company is not treating the historical estimates as current mineral resources or mineral reserves. The historical estimates should not be relied upon. The historical drill results have not been independently verified by the Company and true widths are not known. The sampling program described in this news release is a verification program and will not, on its own, support a mineral resource estimate. Significant additional work, including data compilation and validation, confirmatory drilling and updated geological modeling, would be required before the historical estimates could be upgraded to or verified as current mineral resources. There is no guarantee that any of the historical estimates will be realized, that the results of the sampling program will be consistent with the historical results, or that any mineralization reported in historical drilling will support a current mineral resource estimate.
