• Today (Mexico time) , the second drill commenced drilling at the Target 2 area of El Peru/Las

Brujas as part of Mithril’s 2025, ‘district defining’ 35,000 metre drill programme, at Copalquin

• Drilling at Target 1 resource area successfully intercepted the El Refugio structure 120 metres

down dip on the eastern side, returning a high-grade result:

2.90m @ 9.06 g/t gold, 10.6 g/t silver, from 339.6 m (MTH-LS25-20), including

0.50m @ 44.7 g/t gold, 42.7 g/t silver, from 342m

• The first of a series of deep ( >500 metre) drill holes has been completed on the eastern side of

the Target 1 resource area, successfully intercepting the projected structure at depth. With the

successful ongoing drilling at the Target 1 area, the resource drilling cut-off has been extended

to late May 2025

Mithril Silver and Gold Limited (“Mithril” or “the Company”) (MTH:ASX, MSG:TSXV) announces

high-grade channel results for the Target 2 area at its Copalquin District project, Mexico.

John Skeet, Mithril’s Managing Director and CEO commented:

“The very high-grade channel sampling results and mapping work at the Copalquin District, Target 2 area enhances

the initial assessment of the high prospectivity of the next target area in the district. Drilling has commenced around

the two main historic workings of Las Brujas and El Peru before expanding into adjacent areas of significant historic

mining activity. Drilling at the Target 1 resource area, continues to intercept targeted structures from deep drilling

on the eastern side. We are currently drilling th e second of a series of +500m holes in this area , expanding the

resource update drill programme with anticipated cut -ff date late May 2025 . This may be further extended with

continued success intercepting projected structures defined by our geologic modelling.

COPALQUIN GOLD-SILVER DISTRICT, DURANGO STATE, MEXICO

With 100 historic underground gold -silver mines and workings plus 198 surface workings/pits throughout

70km2 of mining concession area, Copalquin is an entire mining district with high -grade exploration results

and a maiden JORC resource. To date there are several target areas in the district with one already hosting a

high-grade gold-silver JORC mineral resource estimate (MRE) at the Target 1 area (El Refugio-La Soledad)1

and a NI 43-101 Technical Report filed on SEDAR+, supported by a conceptional underground mining study

completed on the maiden resource in early 2022 (see ASX announcement 01 March 2022 and metallurgical test

work (see ASX Announcement 25 February 2022 ). There is considerable strike and depth potential to increase

the resource at El Refugio and at other target areas across the district, plus the underlying geologic system

that is responsible for the widespread gold-silver mineralisation.

With the district -wide gold and silver occurrences and rapid exploration success, it is clear the Copalquin

District is developing into another significant gold -silver district like the many other districts in this prolific

Sierra Madre Gold-Silver Trend of Mexico.

Drill Results Discussion

Drilling at La Soledad, the north-westerly tending structure on the north-eastern side of the Target 1 resource

area, has returned excellent results.

• 2.90m @ 9.06 g/t gold, 10.6 g/t silver, from 339.6 m (MTH-LS25-20), including

o 0.50m @ 44.7 g/t gold, 42.7 g/t silver, from 342m,

MTH-LS25-20 was drilled 120 metres down dip of previous drilling in the area, producing a significant step out

result down dip on the eastern end of the main Refugio structure.

Drill holes MTH-LS25-18 and MTH-LS25-19 did not return reportable intercepts.

ABOUT THE COPALQUIN GOLD SILVER PROJECT

The Copalquin mining district is located in Durango State, Mexico and covers an entire mining district of 70km2

containing several dozen historic gold and silver mines and workings, ten of which had notable production.

The district is within the Sierra Madre Gold Silver Trend which extends north -south along the western side of

Mexico and hosts many world-class gold and silver deposits.

Multiple mineralisation events, young intrusives thought to be system -driving heat sources, widespread

alteration together with extensive surface vein exposures and dozens of historic mine workings, identify the

Copalquin mining district as a major epithermal centre for Gold and Silver.

Within 15 months of drilling in the Copalquin District, Mithril delivered a maiden JORC mineral resource

estimate demonstrating the high-grade gold and silver resource potential for the district. This maiden resource

is detailed below (see ASX release 17 November 2021)^ and a NI 43-101 Technical Report filed on SEDAR+

• 2,416,000 tonnes @ 4.80 g/t gold, 141 g/t silver for 373,000 oz gold plus 10,953,000 oz silver using

a cut-off grade of 2.0 g/t AuEq*

• 28.6% of the resource tonnage is classified as indicated

Table 1 - Mineral resource estimate El Refugio – La Soledad using a cut-off grade of 2.0 g/t AuEq*

* In determining the g old equivalent (AuEq.) grade for reporting, a gold:silver price ratio of 70:1 was determined, using the formula: AuEq grade = Au grade +

((Ag grade/70) x (Ag recovery/Au recovery)). The metal prices used to determine the 70:1 ratio are the cumulative average prices for 2021: gold USD1,798.34 and

silver: USD25.32 (actual is 71:1) from kitco.com. At this early stage, the metallurgical recoveries were assumed to be equal. Subsequent preliminary metallurgical

test work produced recoveries of 91% for silver and 96% for gold (ASX Announcement 25 February 2022). In the Company’s opinion there is reasonable potential

for both gold and silver to be extracted and sold.

^ The information in this report that relates to Mineral Resources or Ore Reserves is based on information provided in the following ASX announcement: 17 Nov

2021 - MAIDEN JORC RESOURCE 529,000 OUNCES @ 6.81G/T (AuEq *), which includes the full JORC MRE report, also available on the Mithril Resources Limited

Website.

The Company confirms that it is not aware of any new information or data that materially affects the information included in the original market announcement

and that all material assumptions and technical parameters underpinning the estimates in the relev ant market announcement continue to apply and have not

materially changed. The company confirms that the form and context in which the Competent Person’s findings are presented have not been materially modified

from the original market announcement.

Mining study and metallurgical test work supports the development of the El Refugio-La Soledad resource with

conventional underground mining methods indicated as being appropriate and with high gold-silver recovery

to produce metal on-site with conventional processing.

Mithril is currently exploring in the Copalquin District to expand the resource footprint, demonstrating its

multi-million-ounce gold and silver potential.

Mithril has an exclusive option to purchase 100% interest in the Copalquin mining concessions by paying US$10M

on or any time before 7 August 2026 (option has been extended by 3 years). Mithril has reached an agreement with

the vendor for an extension of the payment date by a further 2 years (bringing the payment date to 7 August 2028).
