ASSAYS UP TO 997 G/T SILVER, 28 G/T GOLD TARGET 1 EXPANSION

HIGHLIGHTS

Mithril Silver and Gold Limited (“Mithril” or “the Company”) (MTH:ASX) announces further drill

results for the Target 1 resource expansion programme at its Copalquin District project, Mexico.

• 4.60 m @ 5.51 g/t gold, 182.4 g/t silver, from 99m (CDH-162), including

o 2.40m @ 10.24 g/t gold, 335 g/t silver, from 100.40m, Including

0.60m @ 28.0 g/t gold, 997 g/t silver, from 100.40m

CDH-162 was part of the first drilling into an area shallower than the maiden resource model, at the historic

El Refugio mine workings on the western side of the Target 1 resource area.

• 9.00m @ 2.06 g/t gold, 90.26 g/t silver, from 98m (CDH-161)

o Including 1.00m @ 2.14 g/t gold, 259 g/t silver from 99m plus

• 1.60m @ 5.09 g/t gold, 299 g/t silver from 125.60m including

o 0.50m @ 12.15 g/t gold, 758 g/t silver from 126.7m

CDH-161 was drilled at El Cometa on the eastern side of the Target 1 resource area, again adding to the

expanded resource footprint. The recent 33.00m @31.8 g/t gold, 274 g/t silver from surface (CDH-159) was

drilled into a shallower and parallel structure 100 metres west of CDH-161 (see Figure 2). Further drilling will

be completed in this area ahead of the scheduled Target 1 resource update Q1 2025.

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

“Drilling into untested areas in and around the Target 1 maiden resource area continues to successfully expand the footprint

with high to exceptionally high grade results, as we progress our aim to double the resource at this first of multiple targets

in the district with a further 5,000m of drilling to complete over the coming months. Ongoing LiDAR survey interpretation,

together with mapping and drill/channel sample results, further demonstrate a very large epithermal gold-silver system

with significant depth potential across this 10 km wide district. There are at least three further Target 1 size areas for future

drilling plus several areas identified for field work. Our Copalquin District property is advancing to become the next of the

many world-class gold-silver districts in Mexico’s prolific Sierra Madre Gold-Silver Trend.”

COPALQUIN GOLD-SILVER DISTRICT, 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 resource at El Refugio (529koz AuEq @6.81 g/t AuEq)1 supported by a conceptional underground

mining study completed on the maiden resource in early 2022 (see ASX announcement 28 February 2022 and

metallurgical test work (see ASX Announcement 24 February 2024). 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. These districts can host 1 – 5 million ounces of gold plus 50 – 100+ million ounces of silver.

Drillhole Discussion

A total of 4,881.50 metres have been drilled since June 2024, testing Soledad, Cometa and Refugio to better define

dimensions along strike and depth of the mineral evidence that already has shown exceptional silver and gold

potential and multi-event quartz deposition. Additionally, the first drill holes at the historic Copalquin mine, 300m

lower elevation and 900m SE of the Target 1 area, has provided evidence of an epithermal, multi-phase banded

quartz vein, interpreted to be part of the conduit system responsible for the widespread gold-silver mineralization

throughout the district and supporting our model of a large and long lived epithermal gold-silver system.

CDH-161 intersected 9.00m @ 2.06 g/t gold, 90.26 g/t silver, from 98m, including

1.00m @ 2.14 g/t gold, 259 g/t silver from 99m plus

1.60m @ 5.09 g/t gold, 299 g/t silver from 125.60m including

0.50m @ 12.15 g/t gold, 758 g/t silver from 126.7m

In order to establish the vertical and horizontal continuity of Cometa Zone (Refugio E-W Structure and

crosscutting of NW structures) drill testing at depth and along strike of both CDH-159 (33.00m @31.8 g/t gold, 274

g/t silver from surface) and CDH-161 is planned over the coming months.

After completion of detailed mapping and sampling in the underground workings at El Cometa, we can now say

that Fault/Breccias and Fault/Veins along drift are occurring both as high and low angle structures. There is a

dominant 220-250 degree oriented, 50-70 degree angle SE structure offset by a NW structure that has been

developed with channel sample assays pending. Drilling is the follow in this area.

CDH-162 intersected 4.60 m @ 5.51 g/t gold, 182.43 g/t silver, from 99m, including

2.40m @ 10.24 gold g/t gold, 335.03 g/t silver, from 100.40m, plus including

0.60m @ 28 gold g/t gold, 997 g/t silver, from 100.40m

CDH-164 intersected 6.80 m @ 0.70 g/t Au, 36.98 g/t silver, from 87.20m, Including

4m @ 0.93 gold g/t gold, 45.83 g/t silver, from 88m, plus Including

0.60m @ 28 gold g/t gold, 997 g/t silver, from 100.40m

CDH-162, CDH-163 and CDH-164 were drilled in Refugio historic workings shallower than the maiden resource. A

wide quartz breccia zone was intercept along a hydrothermal breccia in all holes. CDH-162 hit Refugio Structure

4.60m @ 5.51 g/t Au, 182.43 g/t Ag, from 99m. CDH-163 hit the El Refugio historic workings from 86.60m to 88.30m

returning with anomalous intercepts of 2.70m @ 0.28 g/t Au, 19.28 g/t Ag from 88.30m, CDH-164 also hit a breccia

zone intercepting 6.80m @ 0.70 g/t Au, 36.98 g/t Ag from 87.20m, including 4m @ 0.93 g/t Au, 45.83 g/t Ag, from

88.00 m

CDH-165 and CDH-166 both holes were drilled on the western margin to provide geological information to support

the development of the geological model. No reportable intercepts from these exploration holes.

Drilling is scheduled to recommence for the second half of the 9,000m program, late this month.

ENVIRONMENTAL, SOCIAL AND GOVERNANCE

The Company philosophy operating in the Copalquin district is to support communities via children’s education and

providing employment opportunities. This includes supporting community schools in the district, employing twenty

people from within the district under the federal employment laws, supporting routine medical visits and

developing infrastructure in the district for long term benefit. This includes the municipal access road, connecting

to the township of El Durazno 12 km east of the Copalquin District, with support for the municipal upgrade works

scheduled for commencement in Q3 2024.

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.

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

* The gold equivalent (AuEq.) values are determined from gold and silver values and assume the following: AuEq. = gold equivalent calculated using and gold:silver

price ratio of 70:1. That is, 70 g/t silver = 1 g/t gold. 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. Metallurgical recoveries are assumed to be approximately equal for both gold and silve r at this early stage. Actual

metallurgical recoveries from test work to date are 96% and 91% for gold and silver, respectively. In the Company’s opinion there is reasonable potential for both gold

and silver to be extracted and sold. Actual metal prices have not been used in resource estimate, only the price ratio for the AuEq reporting.
