MITHRIL DRILLS HIGH-GRADE GOLD-SILVER AT TARGET 1 AND FURTHER

EXPANDS THE DISTRICT SCALE, COPALQUIN, MEXICO

Melbourne, Australia and Vancouver, Canada – January 20, 202 6 - Mithril Silver and Gold Limited

("Mithril” or the "Company") (TSXV: MSG) (ASX: MTH) (OTCQB: MTIRF) is pleased to provide exploration

success at Mithril’s district scale Copalquin property, Durango State, Mexico.

• High-grade in shallow intercepts returned from expansive resource drilling at Target 1 ahead

of the Target 1 mineral resource estimation (MRE) update

• Target 1 drilling highlights include:

o 1.55 m @ 2.11 g/t gold, 5.5 g/t silver from 24.65 m (MTH-RE25-54), plus

1.35 m @ 21.9 g/t gold, 357 g/t silver from 142.75 m, including

0.50 m @ 57.7 g/t gold, 924 g/t silver from 143.6 m

o 3.05 m @ 1.68 g/t gold, 107 g/t silver from 52.0 m (MTH-LS25-53), including

0.50 m @ 9.60 g/t gold, 612 g/t silver from 52.0 m, plus

2.80 m @ 2.29 g/t gold, 60.3 g/t silver from 65.25 m, including

0.50 m @ 10.6 g/t gold, 298 g/t silver from 67.55 m, plus

4.40 m @ 2.18 g/t gold, 14.6 g/t silver from 77.2 m

0.50 m @ 15.5 g/t gold, 66.1 g/t silver from 81.1 m

• Drilling on the western side of Target 1 (150 metre anomalous silver zone intercept in MTH -

RE25-58) extends the District east-west mineralised structure 300 metres west plus extensive

hydrothermal alteration. This large alteration zone indicates significant hydrothermal fluid flow

which possibly represents a major feeder zone in this part of the District. This is further supported

by our recent petrographic work (see discussion below). The east-west structure likely extends a

further 600 metres west to the El Gallo workings where high-grade gold and silver was intercepted

in previous drilling (see ASX announcement date 5 May 2022)1 providing significant scale upside.

• 300 metre down dip extension of the Refugio 1 structure , also on the western side of Target 1

(MTH-RE25-47 and 56), are the deepest intercepts in this area to date which (with the intercept

in MTH-RE25-058) provide vectors for continued expansion of the Copalquin District model.

“The recent drilling at Target 1 has successfully expanded the resource potential for the upcoming Target

1 MRE update and provided important success in the development of the larger District scale model”, said

John Skeet, Managing Director & CEO.

“The drilling on the western side of Target 1 intersected a broad anomalous silver zone with pervasive

hydrothermal alteration associated with the district -scale east –west structure. In low -sulphidation

systems, this style of alteration and silver enrichment is indicative of a well -developed hydrothermal

conduit or feeder zone and supports further potential for mineralisation along strike and at depth as well

as the District bigger picture.

The 300-metre down-dip extension of the Refugio 1 structure confirms vertical continuity of the system

and provides clear scope to expand the Target 1 resource beyond the current model.”

Copalquin District - 2026

Mithril is undertaking an aggressive exploration program in 2026, with 25,000 metres of drilling planned

during the first half of the year across the Copalquin District. Upcoming work will focus on expanding

known mineralized zones, testing new high -priority targets, integratin g district-wide geophysical data,

and continuing to advance the Company’s district-scale exploration thesis. The district features over 100

historic underground workings including several notable producing multi -level mines and 200 s urface

workings. Mapping and sampling across the lower half of the 70 km 2 mining concession area

demonstrates and a large epithermal silver-gold system with multiple target areas for potential resource

growth plus the conduit system responsible for the widespread silver and gold mineralisation.

The nearby 20 km 2 La Dura property has recently been added to the portfolio providing where a LiDAR

survey has been flown (interpretation anticipated in February 2026) and will undergo and aerial magnetic

survey upon completion of the aerial magnetic survey at Copalquin commencing in January 2026.

Target 1 Drilling Discussion

Drilling continued throughout 2025 at the Target 1 area aiming to expand the maiden resource. The

results throughout the year and reported in this announcement have continued to successfully expand

the footprint and fill in areas with the objective to bring more tonnes into classification for a mineral

resource estimate (MRE) update. Approximately 3,000 metres of drilling is to be completed in Q1 2026

to finalise the drilling for the MRE update. 3D modelling of the updated geology including the post mineral

intrusive unit has created a robust and predictable model for the upcoming MRE.

Recently received drill results have intersected very high -grade gold and silver and provided supportive

geological control data for the Target 1 model.

Assay highlights include

o 1.55 m @ 2.11 g/t gold, 5.5 g/t silver from 24.65 m (MTH-RE25-54), plus

1.35 m @ 21.9 g/t gold, 357 g/t silver from 142.75 m, including

Further Evidence of the Large Hydrothermal System

Drilling on the western end of the resource area at Target 1 has continued to provide further evidence of

continuation of the east-west mineralised structure plus extensive hydrothermal alteration.

In a low sulphidation epithermal deposit, the presence of a wide alteration halo combined with silver-rich

mineralization is a strong indicator of a robust, long -lived hydrothermal system and has important

implications for both scale and exploration potential.

A broad alteration halo reflects extensive circulation of neutral to weakly alkaline hydrothermal fluids

through permeable structures and surrounding wall rocks. Alteration assemblages commonly include

quartz, adularia, sericite, with variable carbonate, chlorite and locally developed clay alteration. The

breadth of alteration indicates that fluid flow was not restricted to narrow vein conduits, but instead

affected a large volume of rock, increasing the likelihood of multiple mineralized structures, stacked

veins, or locally disseminated mineralization. From an exploration standpoint, wide alteration halos

provide large, mappable footprints that can be detected through mapping, geochemistry, and remote

sensing, allowing effective vectoring toward higher grade zones.

Figure 7 Drill hole MTH-RE25-58 intercepted a thick anonymously silver rich alteration halo on the western side of Target 1

Silver mineralization is a characteristic feature of low sulphidation epithermal systems and commonly

occurs as electrum, acanthite, native silver, silver sulfosalts, or Ag-bearing base metal sulphides.

Elevated silver grades often reflect boiling, fluid mixing, or rapid pressure changes within the epithermal

environment, processes that are also efficient at precipitating gold. Silver rich zones may be laterally or

vertically offset from gold dominant zones, commonly occupying higher or more distal portions of the

system, and therefore provide valuable vectors toward potentially gold rich feeder structures at depth

or along strike.

Together, a wide alteration halo and significant silver mineralization suggest a well-developed

epithermal system with favourable permeability architecture and strong hydrothermal flux. This

combination increases the probability of discovering additional veins, higher grade shoots, or vertically

zoned precious metal mineralization, and supports the potential for a district scale mineralized system

rather than isolated, narrow veins.
