**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 45?. 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.

Paca Deposit

The Paca Deposit is located 7 km north of the Pulacayo Deposit.

Paca Deposit mineralization occurs at surface and has been defined to date to a maximum depth below surface of approximately 200 metres. The current near surface dimension of the Paca Deposit measures approximately 750 meters North-South by 750 meters East-West. The deposit includes a core zone of feeder-style mineralization associated predominantly with brecciated andesite, plus additional zones of shallowly dipping mantos-style mineralization that are hosted by the surrounding volcano-sedimentary sequence. Mineralization occurs in association with the same Tertiary age volcanic dome complex that produced the Pulacayo Deposit and takes the form of thin veinlets, fracture fillings and disseminations hosted by altered volcaniclastic sedimentary lithologies and altered intermediate to felsic igneous lithologies. The Paca Deposit remains open at depth and along the strike.?

Sensitivity analysis shown in Tables 7 and 8 illustrates various pit-constrained grade-tonnage scenarios at the Paca Deposit based on a range of cut-off grades.

Regional Exploration Potential

Numerous prospective targets which exhibit mineralization expression on surface have been identified around and between the Pulacayo and Paca deposits. The Company has already commenced activities to explore these areas.

Silver Elephant Remarks

Joaquin Merino, VP for South American Operation, commented: “With an Indicated Mineral Resource Estimate 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 Estimate of 13.1 million oz of silver, 122.8 million pounds of zinc and 61.9 million pounds of lead, the Pulacayo Project should be recognized as a top-tier silver project with significant zinc and lead by-product credits. There is demonstrated potential for further resource expansion, and this overall large resource could eventually lead to a district-scale open-pit operation.”
