MITHRIL SILVER AND GOLD DECEMBER 2025 QUARTERLY REPORT

CONTINED EXPLORATION SUCCESS

Melbourne, Australia and Vancouver, Canada – January 30, 202 6 - Mithril Silver and Gold Limited

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

2025 quarterly activities and cash flow report for its Copalquin and La Dura properties in Durango State,

Mexico.

EXPLORATION HIGHLIGHTS

District-Scale Discovery Progressing – Copalquin Gold–Silver Project, Mexico

Copalquin confirmed as a large, vertically extensive epithermal gold –silver system , with

mineralisation defined over 9 km strike length and 1,200 m vertical extent , with multiple targets, a

dominant east –west structural corridor and multiple northwest -trending structures within the 70 km 2

mining concession area.

Target 1 – Refugio–La Soledad (Maiden Resource Growth)

• Ongoing drilling continued to expand and infill the Target 1 resource area and allow development

of a geology model that is now robust and predictive . Updating of the maiden resource at Target

1 is planned for Q2, following a 3,000 metre drill programme to infill key areas in the model .

Beyond the resource update drilling, Target 1 is still open at depth, west towards El Gallo and the

northwest extension of the La Soledad structure.

• Highlight intercepts reported include: 1

o 7.20 m @ 2.78 g/t gold, 148 g/t silver from 260.9 m (MTH-RE25-44), including

2.05 m @ 7.41 g/t gold, 419 g/t silver from 266.05 m, plus

2.80 m @ 3.97 g/t gold, 208 g/t silver from 272.35 m

o 8.03 m @ 7.19 g/t gold, 260 g/t silver from 257.72 m (MTH-RE25-45), including

4.40 m @ 9.87 g/t gold, 507 g/t silver from 260.7 m

The above intercepts extend the Target 1 strike over 30%

Target 5 – Apomal–Candelaria Silver-Rich System (New Target Area – first drilling)

• Maiden drilling confirmed a silver -dominant epithermal system developed at lower elevation

within the Copalquin district. Multiple, parallel NW trending veins hosted in the granodiorite

intrusive in the southwest area of the district.

• Highlight results include: 2

o 2.75 m @ 660 g/t AgEq (2.28 g/t gold, 500 g/t silver) from 93.6 m (AP25-003), including

1.00 m @ 1,714 g/t AgEq (5.80 g/t gold, 1,308 g/t silver) from 94.7 m

o 3.35 m @ 366 g/t AgEq (1.71 g/t gold, 246 g/t silver) from 90.15 m (AP25-005), including

0.80 m @ 427 g/t AgEq (1.51 g/t gold, 321 g/t silver) from 149.5 m

• Surface and channel sampling up to 3,300 g/t Ag and 2.0 g/t Au over 1.4 m3 and 4,520 g/t Ag and

38.3 g/t Au over 0.60 m4 from historic workings.

• Drilling to date has tested only a small proportion of mapped veins, highlighting substantial

upside potential at this large target area

Target 3 – El Jabali-Guadelupe (Maiden Drill Programme in January 2026)

• Mapping and sampling continued to define a coherent target on the eastern side of the Copalquin

system adjacent to one of the multiple rhyolite domes that feature across the 10 km long district

trend

• Channel sampling highlights included 0.65 m @ 16.0 g/t Au, 1,275 g/t Ag (El Jabali area)4.

• Subsequent to the end the quarter, the maiden drill programme has commenced at Target 3 in

January 2026.5

District Geological Model Strengthened

Integrated mapping, sampling, spectral analysis and petrography have confirmed:

• a dominant east–west corridor hosting high-grade gold-silver mineralisation;

• northwest-trending and cross-cutting ‘feeder’ structures

• vertically zoned silver and gold mineralisation ranging from silver rich to gold rich across the

district for 9 km.

• multiple mineralised centres analogous to Mexican epithermal districts throughout the Sierra

Madre Gold-Silver trend.

• Subsequent to the end of the quarter, an aerial magnetic survey commenced over the Copalquin

mining concession area. This is expected to confirm and reveal the key structures, including

shear zones, faults and other geologic features , responsible for the widespread silver and gold

mineralisation across the Copalquin District

Acquisition of the La Dura Mining Concessions, Adjacent to Mithril’s Copalquin Property6

La Dura consists of 5 contiguous mining concessions with a total area of 2,052 hectares and located in

Durango State, Mexico, 5 km from the town of El Durazno and 20 km from Mithril’s flagship Copalquin

property.

The property hosts a significant Au ‐Ag sheeted to stockwork vein system associated with NW striking

faults in Tertiary rhyolite. Mineralization occurs on surface along 650 metres of strike and has been mined

in the San Manuel shoot at the La Dura historic mine, to about 140 metres depth. Veins are characterised

by low sulphide mineralisation with minimal to no alteration of the host rhyolite tuff. Historically, the

veins have been exploited and explored solely on the progress of the underground workings and assaying.

The project warrants property scale mapping, wide spaced soil sampling and channel sampling to

develop targets for drill testing. A LiDAR survey has been completed (awaiting interpretation) and an

aerial magnetic survey is scheduled to be flown upon completion of the survey underway at Copalquin,

both as precursors to a field programme.

The veins at the various workings appear to be hosted by upper series volcanic rocks and may have

significant depth potential should they extend into the lower series andesitic rocks at some greater

depth.

Corporate

• The Annual General Meeting was held on 5th November 2025 with all resolutions passed

• Cash balance of A$14.1M at end of the December 2025 quarter and Mithril remains debt free

• Mexican value added tax refunds have slowed towards the end of 202 5. A refund of MXN3.8M

(~A$0.32M) was received in January 2026. Approximately MXN10M (~A$0.8M) of refunds for 2025

are in process and it is anticipated these will complete over the coming months.

Commenting on the December 2025 quarter, Managing Director and CEO John Skeet said:

“The December quarter marked another period of significant exploration progress at Copalquin. Drilling

at Target 1 continued to expand the scale of the mineralised system ahead of the upcoming resource

update, while Target 5 has emerged as a compelling silver-rich growth opportunity within the south-west

of the district.

At the same time, we advanced Target 3 to be drill ready (commenced January 2026) and strengthened

our district-scale geological model through systematic mapping, sampling and geophysical work. These

results continue to reinforce our view that Copalquin represents a large, vertically extensive epithermal

gold–silver system with multiple high-grade centres and substantial resource growth potential. Firming

of the key structural targets for drill testing in the coming months will follow completion of the aer ial

magnetic survey (commenced in January 2026).

The addition of the nearby La Dura mining concessions to the portfolio takes advantage of our established

presence in the area to progress another compelling gold -silver property, utilising our Copalquin

experience and with minimal financial commitment.

With a strong treasury and multiple drill program mes underway, Mithril is well positioned to achieve its

exploration milestones in 2026.”

ABOUT THE COPALQUIN AND LA DURA GOLD SILVER PROPERTIES

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, integrating 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 portfoli o where a LiDAR survey has

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

February 2026, upon completion of the aerial magnetic survey at Copalquin.

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

estimate at the first of several target areas (Target 1), 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+

Target 1 Maiden Resource:

• Indicated 691 kt @ 5.43 g/t gold, 114 g/t silver for 121,000 oz gold plus 2,538,000 oz silver

• Inferred 1,725 kt @ 4.55 g/t gold, 152 g/t silver for 252,000 oz gold plus 8,414,000 oz silver

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

• 28.6% of the resource tonnage is classified as indicated

* In determining the gold equivalent (AuEq.) grade for reporting, a gold:silver price ratio of 70:1 was determined, using th e

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.

For silver equivalent (AgEq.) grade reporting, the same factors as above are used with the formula AgEq grade = Ag grade + (( Au

grade x 70) x (Au recovery/Ag recovery))

At this early stage, the metallurgical recoveries were assumed to be equal (93%). Subsequent preliminary metallurgical test work

produced recoveries of 91% for silver and 96% for gold (ASX Announcement 25 February 2022) and these will be used when the

resource is updated in the future. In the Company’s opinion there is reasonable potential for both gold and silver to be extracted

and sold.
