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.

Exploration Activity Discussion

By the end of the March 2025 quarter, a total of 11,225 metres were drilled since commencing in June 2024 ,

including 5,800 metres completed in the March 2025 quarter.

Target 1 Area – Resource Update Drilling

Drilling during the March 2025 quarter focussed on the eastern side of the Target 1 resource around the La Soledad

structure with the multiple high-grade gold and silver intercepts returned resulting in extended drilling in this area.

The drill has now been moved to the El Refugio structure to test potential down -dip extensions to mineralization

along the main east-west striking vein trend and along northwest-southeast striking structures which may intersect

or crosscut the main trend. The plan includes drilling a series of 500 -600m long holes in this area before moving

to test potential near -surface extensions of the Refugio structure at the western extents of Target 1. Additional

follow up drilling is planned for both targets, pending positive assay results from the current program.

Target 2 Area – Maiden Drill Programme

An important milestone was reached at the end of the March quarter, with the mobilisation of the second drill rig

to the Copalquin District which will facilitate the planned 35,000 metres of drilling for 2025.

The second drill rig commenced the maiden drill programme for Target 2 in early April 2025, which has the potential

to become the second high-grade gold-silver resource area to be defined within the Copalquin District.

District Mapping and Sampling

The district mapping and sampling is progressing rapidly with highly prospective areas developing into future drill

targets. Mapping work during the quarter expanded into the southwest area of the district where there are several

historic mines workings in this lower elevation area.

Figure 1 LiDAR identified historic workings across the 70km2 district. Target 1 area current drilling location, channel sampling area and the high

priority drill target areas of Las Brujas-El Peru (Target 2) and La Constancia-El Jabali (Target 3). Several new areas highlighted across the district

for follow-up work.

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

area, returned excellent intercepts ahead of the planned resource update. Results for drill holes MTH -LS25-08 to

MTH-LS25-11 are summarised below.

• 4.95m @ 20.5 g/t gold, 1,833 g/t silver, from 107m (MTH-LS25-11), including

Further drilling during the quarter on the northwest area of La Soledad at Target 1 produced returned high-grade

intercepts with drill holes MTH-LS25-12 to MTH-LS25-17 summarised below.

• 1.99m @ 4.29 g/t gold, 72.6 g/t silver, from 98.26 m (MTH-LS25-12), including

o 0.50m @ 15.4 g/t gold, 214 g/t silver, from 98.26m,

• 2.75m @ 1.23 g/t gold, 81.2 g/t silver, from 108.75m

o 0.50m @ 5.16 g/t gold, 334 g/t silver, from 108.75m,

• 3.62m @ 9.62 g/t gold, 55.2 g/t silver, from 97.7m, (MTH-LS25-13) (incl. 0.8m void), including

o 0.72m @ 45.5 g/t gold, 221 g/t silver, from 100.6m

• 0.46m @ 4.11 g/t gold, 83.8 g/t silver, from 170.54m

• 5.00m @ 5.08 g/t gold, 22.1 g/t silver, from 108.06m, (MTH-LS25-14), including

o 1.00m @ 16.7 g/t gold, 72.7 g/t silver, from 110.0m

• 0.84m @ 1.78 g/t gold, 35.6 g/t silver, from 148.66m

• 0.50m @ 1.72 g/t gold, 11.9 g/t silver, from 102.15m, (MTH-LS25-15)

• 3.35m @ 26.5 g/t gold, 1,046 g/t silver, from 215.15m, (MTH-LS25-16)

• 0.65m @ 12.1 g/t gold, 292 g/t silver, from 280.35m

• 0.50m @ 3.53 g/t gold, 3.2 g/t silver, from 335.0m

MTH-LS25-14 returned higher AuEq grades than previously estimated in the 2021 MRE along both the Soledad

main and Soledad mid veins. The first intercept represents a roughly 20m down -dip extension of high-grade

mineralization from CDH-008 and CDH-011 along the Soledad main vein, with the second intercept 42m down -dip

from MTH-LS-25-12 and 17m up-dip from CDH-013 along the Soledad mid vein.

MTH-LS25-16 returned higher AuEq grades than previously estimated in the 2021 MRE along the Soledad main

vein, confirming a roughly 20m down -dip extension of high-grade mineralization from MTH-LS25-11. The deeper

two intercepts (from 280.35m and 335m) are both in the footwall of the Leon vein, in areas which were estimated

as waste in the 2021 MRE. Both intercepts are open up -dip, down-dip, and along strike, and while narrow, could

represent additional targets for resource growth in the Soledad system.

MTH-LS25-12 confirmed continuity in mineralization along the Soledad vein approximately 18m southeast from

historical mine workings.

MTH-LS25-13 confirmed continuity in mineralization along the Soledad vein approximately 10m west from

historical mine workings and returned significantly higher grades than nearby CDH-003 (12m down-dip).

Drill hole MTH-LS25-17 did not return a reportable intercept.

At El Cometa on the eastern side of the Target 1 resource area, two holes returned multiple shallow intercepts.

The near surface (<100m down hole) cut -off for reporting the intercepts in the El Cometa area is lower (0.25 g/t

AuEq2 compared with 1.00 g/t AuEq2 for >100m down hole intercept reporting) reflecting its potential for lower cost

mining methods.

El Cometa features a broad mineralised structure with cross cutting structures hosting very high -grade gold and

silver, such as reported from drill hole CDH-159 in 2024 (33.00m @31.8 g/t gold, 274 g/t silver from surface).

Intercepts for MTH-EC25-06 and MTH-EC25-07 are summarised below and have continued to build on the excellent

results from this shallow mineralisation.

• 1.00m @ 1.56 g/t gold, 58.3 g/t silver from 31.0m (MTH-ES25-07)

• 1.00m @ 0.72 g/t gold, 29.0 g/t silver from 33.5m

• 6.00m @ 1.33 g/t gold, 178.6 g/t silver from 95.0m, including

o 1.70m @ 4.07 g/t gold, 588 g/t silver from 98.15m

• 7.00m @ 1.56 g/t gold, 70.5 g/t silver from 126m, including

o 1.00m @ 8.70 g/t gold, 272 g/t silver from 127m

• 2.90m @ 0.83 g/t gold, 88.0 g/t silver from 22.6m (MTH-ES25-06)

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 distri ct 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 Dist rict, with support for the municipal upgrade works

scheduled for commencement in October 2024.

ABOUT THE COPALQUIN GOLD SILVER PROJECT

The Copalquin mining district is located in Durango State, Mexico and covers an entire mining district of 70km 2

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.
