Economic Studies

NEWS RELEASE

SILVER TIGER ANNOUNCES PFS WITH NPV OF US$222M FOR THE

STOCKWORK ZONE OF THE EL TIGRE SILVER-GOLD PROJECT, SONORA,

MEXICO

HALIFAX, NOV A SCOTIA – October 22, 2024 – Silver Tiger Metals Inc. (TSXV:SLVR and OTCQX:SLVTF)

("Silver Tiger" or the “Corporation”) is pleased to announce a Preliminary Feasibility Study (“PFS”) for its 100%

owned, silver-gold El Tigre Project (the "Project" or "El Tigre") located in Sonora, Mexico. The PFS is focused on

the conventional open pit mining economics of the Stockwork Mineralization Zone defined in the updated Mineral

Resource Estimate (“MRE”) (Figure 1). The updated MRE also contains an Out-of-Pit Mineral Resource that Silver

Tiger plans to study in a Preliminary Economic Assessment in H1-2025.

Highlights of the PFS are as follows (all figures in US dollars unless otherwise stated):

• After-Tax net present value (“NPV”) (using a discount rate of 5%) of US$222 million with an After-Tax IRR

of 40.0% and Payback Period of 2.0 years (Base Case);

• 10-year mine life recovering a total of 43 million payable silver equivalent ounces (“AgEq”) or 510 thousand

payable gold equivalent ounces (“AuEq”) , consisting of 9 million silver ounces and 408 thousand gold

ounces;

• Total Project undiscounted after-tax cash flow of US$318 million;

• Initial capital costs of $86.8 million, which includes $9.3 million of contingency costs, over an expected 18-

month build, expansion capital of $20.1 million in year 3 and sustaining capital costs of $6.2 million over the

life of mine (“LOM”);

• Average LOM operating cash costs of $973/oz AuEq, and all in sustaining costs (“AISC”) of $1,214/oz AuEq

or Average LOM operating cash costs of $12/oz AgEq, and all in sustaining costs (“AISC”) of $14/oz AgEq;

• Average annual production of approximately 4.8 million AgEq oz or 56.7 thousand AuEq oz; and

• Three (3) years of production in the Proven category in the Phase 1 Starter Pit.

Glenn Jessome, President & CEO stated “We are very pleased with the work completed by our consultants and our

technical team on the PFS for the open pit at El Tigre. The open pit delivers robust economics with an NPV of US$222

million, an initial capital expenditure of US$87 million, and a payback of 2 years with 3 years of production in the

Proven category in the ‘Starter Pit using metal prices greatly discounted to the spot price.” Mr. Jessome continued

“This is a pivotal point for our Company as we now have a clear path forward to making a construction decision for

the open pit. The open pit has good grade (48 g/t AgEq), low strip ratio (1.7:1), and wide benches (~150 m) with

mineralization at surface. With such positive parameters and with our VP of Operations Francisco Albelais, a career

expert in the construction of large heap leach mines in Mexico, we are confident we will be able to advance the Project

very quickly.” Mr. Jessome concluded “The open pit is only one component of El Tigre as we have also today

delivered over 113 Mozs AgEq in the underground Mineral Resource Estimate and disclosed an Exploration Target

establishing 10 to 12 million tonnes at 225 to 265 g/t AgEq for 73 to 100 Moz AgEq. This disclosed ‘near -mine’

Mineral Resource and potential, when coupled with the fact that only 30% of this prolific Property has been explored,

shows the value of the El Tigre Project. The Company will also continue to work on this substantial underground

Mineral Resource by starting underground drilling immediately, and plan to release an underground PEA in H1-2025.”

Highlights of the updated Mineral Resource

• Increased confidence in MRE, with increase of 132% in Total Measured & Indicated Silver Equivalent

(“AgEq”) Ounces from September 2023 MRE, with 59% increase in Measured & Indicated AgEq grade;

• Total Measured & Indicated Mineral Resource of 200 Moz AgEq grading 92 g/t AgEq contained in 68.0

million tonnes (“Mt”);

• Inferred Mineral Resource of 84 Moz AgEq grading 180 g/t AgEq contained in 14.5 Mt; and

• Inclusion of Out-of-Pit Mineral Resource of 5.3 Mt Measured & Indicated Mineral Resource at grade of

255 g/t AgEq and 10.1 Mt Inferred Mineral Resource grading 216 g/t AgEq.

Preliminary Feasibility Summary

The PFS was prepared by independent consultants P&E Mining Consultants Inc. (“P&E”), with metallurgical test

work completed by McClelland Laboratories, Inc. – Sparks, Nevada, process plant design and costing by D.E.N.M.

Engineering Ltd., and environmental and permitting led by CIMA Mexico. Following are tables and figures showing

1. Grades shown are LOM average process plant feed grades include only OP sources. Mining losses and external dilution of 3.7% were incorporated in the mining schedule.

2. Column testing indicated both variable gold and silver recovery for the oxide material vs the previously reported non-discounted PEA (83% and 64%) at a 3/8-in crush size. In the process design and

financial model for the PFS process design and financial model recoveries have been discounted by 3% for leaching in the field versus optimum conditions in the laboratory and shown accordingly.

The presence of transition and sulfide zones has affected both the gold and silver recoveries and are shown as separate recoveries. These are reasonable and appropriate for use in this PFS design and

economic analysis.

Capital and Operating Costs

The El Tigre Project has been envisioned as an open pit mining operation starting at a processing rate of 7,500 tonnes

per day for years 1-3 and then ramping up to 15,000 tonnes per day by year 4 after 1 year construction for ramp up in

year 3.

The process plant is comprised of conventional three (3) stage crushing to an optimum -3/8 inch (10 mm) crush size.

The crushed material will be conveyed and loaded on the lined pad areas. A series of pumping and piping will allow

irrigation of the stacked heap material and subsequent production of pregnant solution to flow to the respective

impoundment pond. The pregnant solution will be pumped to the recovery facility consisting of the Merrill – Crowe

process (zinc precipitation) and refinery to produce the gold and silver dore for marketing. The process barren solution

will be recycled (with NaCN addition) and pumped back to the heap for further leaching. The process plant location

will be adjacent to the pad and pond infrastructure area.

Water supply to the process plant is provided by pumping from nearby Bavispe R iver to the process area water

distribution system and high voltage grid power will be installed by the local utility to supply process and

infrastructure electrical requirements. Expansion capital includes the cost to increase the process plant capacity from

7,500 tonnes per day to 15,000 tonnes per day as noted in Year 4 of operation.

Mining

Open pit mining will be contracted and carried out by drill and blast followed by conventional loading and truck

haulage to the waste rock storage facilities and the process plant.

Metallurgy

A detailed metallurgical test program was carried out by McClelland Laboratories, Inc., Sparks, Nevada on six (6) El

Tigre starter pit samples. The program included crushing, coarse bottle rolls, and column testing at both 80% passing

3/8 inch and 1/2 inch (10 and 12 mm) crush size for five (5) of the six samples. One low grade sample was only

crushed to 80% passing 1-1/2 inch (38 mm) as an indication of low grade leachability. The leach samples comprised

of drill core sample representing the starter pit and during the testing process it became apparent that the presence of

transition and sulfide zones are in the starter pit thus affecting the base design recoveries. This variable test program

(column and coarse bottle roll) estimated oxide average gold and silver respective metallurgical recoveries of 8 6%

Au and 48% Ag at the 3/8 inch (10 mm) crush. The transition and sulfide zones had estimated recoveries of 59% Au

and 43% Ag. Further percolation testing also confirmed no requirement for agglomeration of the crushed material is

required prior to loading on the leach pad.

Mineral Resource Estimate

The basis for the PFS is the Mineral Resource Estimate completed by P&E for the El Tigre Project located in Sonora

State, Mexico, which has an effective date of October 22, 2024, with an NI 43-101 Technical Report to be filed within

45 days of this news release. A summary of the Mineral Resource Estimate is provided in Table 5.

Table 5 – Updated Mineral Resource Estimate October 2024

1) Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by

environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

2) The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Reso urce and must not be converted to a Mineral

Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.

3) The Mineral Resources were estimated in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and

Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definiti ons and adopted by the CIM Council.

4) Historically mined areas were depleted from the Mineral Resource model.

5) Prices used are US$2,000/oz Au, US$25/oz Ag, US$4.00/lb Cu, US$0.95 lb Pb and US$1.25/lb Zn.

6) The pit-constrained AuEq respective oxide and sulfide cut -off grades of 0.10 and 0.15 g/t were derived from 40% Ag and 83% Au oxide process recovery, 40% Ag and 56%

Au sulfide process recovery, US$5.25/tonne process and G&A cost. The constraining pit optimization parameters were $2.00/t mining cost a nd 45-degree pit slopes. Regarding

recoveries, the PFS recovery for Ag in oxide material was increased to 45% after a more detailed study was complete after the MRE was finalized.

7) The out-of-pit AuEq cut-off grade of 1.50 g/t was derived 93% Ag and 89% Au process recovery, US$28/tonne process and G&A cost, and a $60/tonne mining cost. The out -

of-pit Mineral Resource grade blocks were quantified above the 1.50 g/t AuEq cut -off, below the constraining pit shell and within the constraining mineralized wireframes.

Out–of-Pit Mineral Resources are restricted to the El Tigre Main Veins, which exhibit historical continuity and reasonable potential for extraction by cut and fill and long hole

mining methods.

8) The Low-Grade Stockpile AuEq cut-off grade of 0.54 g/t was derived from 85% Ag and 85% Au recovery US$28/tonne process and G&A cost, and a $2/tonne mining cost.

9) The Tailings AuEq cut-off grade of 0.55 g/t was derived from 82% Ag and 83% Au process recovery, US$28.72/tonne process and G&A cost.

10) AgEq and AuEq were calculated at an Ag/Au ratio of 166:1 (oxide) and 122:1 ( sulfide) for pit-constrained Mineral Resources.

11) AgEq and AuEq were calculated at an Ag/Au ratio of 77:1 for out -of-pit Mineral Resources.

12) AgEq and AuEq were calculated at an Ag/Au ratio of 80:1 for Low -Grade Stockpile Mineral Resources.

13) AgEq and AuEq were calculated at an Ag/Au ratio of 79:1 for Tailings Mineral Resources

14) Totals may not sum due to rounding.

2024 El TIGRE MINERAL RESOURCE ESTIMATE (1-14)

Mineral Resource Estimate Methodology – El Tigre Project

The El Tigre Project includes the El Tigre Veins, El Tigre Tailings and the El Tigre Low-Grade Stockpile.

The databases used for this Mineral Resource update contain a total of 20,149 collar records that contribute directly

to the Mineral Resource Estimate and includes collar, survey, assay, lithology and bulk density data. Assay data

includes Au g/t, Ag g/t, Cu %, Pb % and Zn % grades. The drilling extends approximately five km along strike.

P&E Mining Consultants Inc. (“P&E”) collaborated with Silver Tiger personnel to develop the mineralization models,

grade estimates, and reporting criteria for the Mineral Resources at El Tigre. Mineraliz ed domains were initially

developed by Silver Tiger and were reviewed and modified by P&E. A total of twenty-seven individual mineralized

domains have been identified through drilling and surface sampling. Interpreted mineralization wireframes were

developed by Silver Tiger geologists for the El Tigre Veins based on logged drill hole lithology, assay grades and

historical records. Silver Tiger identified continuous zones of mineralization from assay grades equal to or greater

than 0.30 g/t AuEq with observed continuity along strike and down- dip, using a calculated Ag:Au equivalent factor

of 75:1. The selected intervals include lower grade material where necessary to maintain wireframe continuity

between drill holes.

P&E developed mineralized domains for the El Tigre Low -Grade Stockpile and the El Tigre Tailings based on

lithological logging and LiDAR surface topography.

Assay samples were composited to either 1.00 m or 1.50 m for the vein domains. No compositing was used for the

Low-Grade Stockpiles and Tailings models. Composites were capped prior to grade estimation based on the analysis

of individual composite log-probability distributions.

A total of 5,542 bulk density values were taken by Silver Tiger from drill hole core. Mineralized bulk density values

were assigned for each of the El Tigre Main Veins based on the median vein measurement. For the El Tigre North

Veins, a bulk density of 2.65 t/m3 was assigned for the veins and a value of 2.42 t/m3 was assigned for the Protectora

Halo. For the Low-Grade Stockpile a value of 1.60 t/m3 was assigned, and for the Tailings a value of 1.39 t/m 3 was

used based on 37 nuclear density measurements.

Vein block grades for gold and silver were estimated by Inverse Distance Cubed (“ID3”) interpolation of capped

composites using a minimum of four and a maximum of twelve composites. Vein block grades for copper, lead and

zinc were estimated by Inverse Dist ance Squared (“ID2”) interpolation of capped composites using a minimum of

four and a maximum of twelve composites.

Nearest-Neighbour grade interpolation was used for the Low -Grade Stockpiles, and for the Tailings, block grades

were estimated by ID2 estimation of capped assays using a minimum of four and a maximum of twelve samples.

For the El Tigre Main Veins, blocks within 30 m of three or more drill holes/channels were classified as Measured

Mineral Resources, and blocks within 60 m of three or more drill holes/channels were classified as Indicated Mineral

Resources. All additional estimated blocks were classified as Inferred Mineral Resources.

For the North Veins, blocks interpolated by at least two drill holes within 50 m were classified as Indicated Mineral

Resources. Blocks interpolated by at least one drill hole within a maximum distance of 200 m were classified as

Inferred Mineral Resources.

For the Low-Grade Stockpiles, blocks within 15 m of two or more drill holes were classified as Indicated Mineral

Resources. All additional estimated blocks were classified as Inferred Mineral Resources.

For the Tailings, blocks within 30 m of three or more auger or core drill holes were classified as Measured Mineral

Resources. Blocks within 60 m of two or more auger/drill holes/pits or trenches were classified as Indicated Mineral

Resources. All additional estimated blocks were classified as Inferred Mineral Resources.

P&E considers that the block model Mineral Resource Estimates and Mineral Resource classification represent a

reasonable estimation of the global mineral resources for the El Tigre Project with regard to compliance with generally

accepted industry standards and guidelines, the methodology used for estimation, the classification criteria used and

the actual implementation of the methodology in terms of Mineral Resource estimation and reporting. The Mineral

Resources have been estimated in conformity with the requirements of the CIM “Estimation of Mineral Resource and

Mineral Reserves Best Practices” guidelines as required by the Canadian Securities Administrators’ National

Instrument 43-101. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
