VANCOUVER, BC / ACCESSWIRE / October 13, 2020 / Silver Elephant Mining Corp. ("Silver Elephant" or "the Company") (TSX:ELEF, OTCQX:SILEF, Frankfurt:1P2N) announces the results of a National Instrument 43-101 ("NI43-101") compliant Mineral Resource Estimate for the Pulacayo silver-lead-zinc project ("Pulacayo Project") in Bolivia. The Pulacayo Project consists of the Pulacayo Deposit and Paca Deposit (7km north of Pulacayo deposit). The project is 107 km northeast of Sumitomo Corporation's San Cristobal silver mine, 171 km southwest of New Pacific's Silver Sands discovery, and 139 km north of Pan American Silver Corp.'s San Vicente silver mine.

The Mineral Resource Estimate has an effective date of October 13, 2020 and includes an Indicated Mineral Resource of 106.7 million oz of silver, 1,384.7 million pounds of zinc, and 693.9 million pounds of lead, and an Inferred Mineral Resource of 13.1 million oz of silver, 122.8 million pounds of zinc and 61.9 million pounds of lead. Silver Elephant's wholly owned Bolivian subsidiary has invested over US$30 million at the Pulacayo Project since 2006.

The Mineral Resource Estimate was prepared by Mercator Geological Services Limited ("Mercator") under supervision of Matthew Harrington, P. Geo., who is an independent Qualified Person as defined under NI 43-101. A technical report documenting the Mineral Resource Estimate will be filed by the Company within 45 days.

**Notes:

1. Mineral Resources were prepared in accordance with NI 43-101, the CIM Definition Standards (2014) and CIM MRMR Best Practice Guidelines (2019).

2. *Ag Eq. = Silver Equivalent (Recovered) = (Ag g/t*89.2%)+((Pb%*(US$0.95/lb. Pb/14.583 Troy oz./lb./US$17 per Troy oz. Ag)*(10,000*91.9%))+((Zn%*(US$1.16/lb. Zn/14.583 Troy oz./lb./US$17 per Troy oz. Ag)*(10,000*82.9%)). Sulphide zone metal recoveries of 89.2% for Ag, 91.9% for Pb, and 82.9% for Zn were used in the Silver Equivalent (Recovered) equation and reflect metallurgical testing results disclosed previously for the Pulacayo Deposit. A metal recovery of 80% Ag was used for oxide zone Mineral Resources.

3. Metal prices of US$17/oz Ag, US$0.95/lb Pb, and US$1.16 Zn apply. A currency exchange rate of CDN$1.00 to US$0.75 applies.

4. Pit-Constrained Mineral Resources are defined for each deposit within optimized pit shells with average pit slope angles of 45⁰. The Pulacayo Deposit Mineral Resource Estimate was optimized at a 12.3:1 strip ratio and the Paca Deposit Mineral Resource Estimate was optimized with at a 4.3: strip ratio.

5. Base-case sulfide zone pit optimization parameters include: mining at US$2.00 per tonne; combined processing and G&A at US$12.50 per tonne processed; haulage at US$0.50 per tonne processed for Pulacayo and US$2.00 per tonne processed for Paca.

6. Base-case oxide zone pit optimization parameters include: mining at US$2.00 per tonne; combined processing and G&A at US$23.50 per tonne processed; haulage at US$0.50 per tonne processed for Pulacayo and US$2.00 per tonne processed for Paca.

7. Pit-constrained sulphide zone Mineral Resources are reported at a cut-off grade of 30 g/t Ag Eq. within the optimized pit shells and pit-constrained oxide zone Mineral Resources are reported at a cut-off grade of 50 g/t Ag within the optimized pit shells. Cut-off grades reflect total operating costs used in pit optimization and are considered to define reasonable prospects for eventual economic extraction by open pit mining methods.

8. Out of Pit Mineral Resources are external to the optimized pit shells and are reported at a cut-off grade of 100 g/t Ag Eq. They are considered to have reasonable prospects for eventual economic extraction using conventional underground methods such as long hole stoping based on a mining cost of $35 per tonne and processing and G&A cost of $20 per tonne processed.

9. "Total" Mineral Resources for the Pulacayo Deposit Combined Pit-Constrained and Out-of-Pit Mineral Resource Estimate is the tonnage-weighted average summation of Pit-Constrained and Out-of-Pit Pulacayo Mineral Resources.

10. "Total" Mineral Resources for the Pulacayo Project Mineral Resource Estimate is the tonnage-weighted average summation of total Pulacayo Deposit and Paca Deposit Mineral Resources.

11. Mineral Resources were estimated using Ordinary Kriging methods applied to 1 m downhole assay composites capped at 2,300 g/t Ag, 13% Pb and 15% Zn.

12. Bulk density was interpolated using Ordinary Kriging methods for Pulacayo Mineral Resources. An average bulk density of 2.32 g/cm3 or 2.24 g/cm3 was applied to Paca Mineral Resources based on grade domain solid models.

13. Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.

14. Mineral Resource tonnages have been rounded to the nearest 5,000; totals may vary due to rounding.

There are no known legal, political, environmental, or other risks identified by the Company at the October 13, 2020 effective date that would materially affect potential future development of the Pulacayo Project.

Pulacayo Deposit

The Pulacayo and Paca Deposits are interpreted to be low-to-intermediate sulphidation epithermal deposits.

The Pulacayo Deposit occurs within the Tertiary age Pulacayo volcanic dome complex that consists of older sedimentary rocks of the Silurian Quenhua Formation and the intruding andesitic volcanic rocks of the Rothchild and Megacristal units. Mineralization hosted by volcanic rocks can be tens of meters in thickness and typically consists of discrete veins plus stockworks of narrow veins and veinlets that occur within argillic alteration host rock envelopes. Veins are commonly banded in texture and can contain semi-massive to massive sulphides. The primary minerals of economic importance at Pulacayo are tetrahedrite, galena and sphalerite. There are also silver sulfosalts and native silver which contribute to deposit silver grades. Mineralization is controlled by an east-west oriented normal fault system which links two northeast trending, steeply dipping, regional strike slip faults.

Historic Pulacayo mine production was predominantly from the Tajo vein system (TVS) which extends over a strike length of more than 2.5 km and down dip 1,000 meters. Resource drilling spans 1.4 km mineralized strike and extends down dip 400 meters from the surface. It covered an area that's approximately 30% of TVS. There is the potential of discovering additional resources by drilling along the strike and at depth.

The sensitivity analysis shown in Table 4 and Table 5 illustrates various pit-constrained grade-tonnage scenarios for the Pulacayo deposit based on a range of cut-off grades. Table 6 shows sensitivity analysis for out-of-pit grade tonnage scenarios.
