HIGHLIGHTS

• Infill and extensional drilling at La Negra SE confirms broad, shallow zone of oxide silver-gold mineralisation over 850m strike and 175m vertical extent, open to the SE and at depth.
• New standout drill results (from the SE of La Negra SE) include:

JDD0113-25	107m at 165gpt AgEq (1gpt Au, 70gpt Ag) from 18m, including: 55.6m at 245gpt AgEq (1.7gpt Au, 81gpt Ag) from 67.9m
JDD0118-25	74m at 134gpt AgEq (0.7gpt Au, 67gpt Ag) from 6m 35.6m at 207gpt AgEq (1.3gpt Au, 81gpt Ag) from 38.4m
JDD0108-25	81m at 107gpt AgEq (0.5gpt Au, 60gpt Ag) from 2m 15m at 183gpt AgEq (1.4gpt Au, 49gpt Ag) from 62m
JDD0112-25	46.2m at 117gpt AgEq (0.3gpt Au, 91gpt Ag) from 6.8m 27m at 145gpt AgEq (0.4gpt Au, 106gpt Ag) from 21m
JDD0111-25	58m at 100gpt AgEq (0.6gpt Au, 39gpt Ag) from 89m 7.45m at 1G3gpt AgEq (1.4gpt Au, 55gpt Ag) from 135m
JDD0123-25	56m at 106gpt AgEq (0.4gpt Au, 66gpt Ag) from 5m 10.7m at 1G5gpt AgEq (1.2gpt Au, 79gpt Ag) from 33.3m

• True thickness ranges from 15 to 75 metres, supporting bulk open pit mining potential.
• Drilling resumed 5 January 2026 and includes three diamond rigs and one Reverse Circulation (RC) rig. At La Negra SE, infill drilling on a 50m by 25m grid is nearing completion with 8 holes remaining to support a high confidence Indicated Resource.
• Based on timing and new results, the Company will proceed directly to a Pre-Feasibility Study (PFS)-level Mineral Resource Estimate (MRE), covering La Negra, La Negra SE and La Morocha. Infill drilling at La Morocha SE will commence in February and is upside for future resource estimates and mining studies.
• PFS workstreams completed during December 2025 include baseline environmental studies, geotechnical drilling (9 holes) and comminution drilling (3 holes) with full HQ samples shipped to Nevada for ore hardness testing.
• Regional exploration and soil geochemical sampling SE of La Morocha defines the 650m by 150m “La Rubia” silver anomaly (2500ppb) confirming the potential for additional shallow discoveries along strike from La Morocha (Figure 3 to 4).

Managing Director Todd Williams states:

“Infill drilling at La Negra SE continues to deliver wide, shallow zones of oxide silver-gold mineralisation with excellent continuity across the full 850-metre strike length. These results confirm the scale and geometry required for conventional open-pit development and support our decision to move directly to a Pre-Feasibility Study Mineral Resource Estimate.

With infill drilling nearing completion, geotechnical and comminution programs already underway, and three key prospects – La Negra, La Negra SE and La Morocha – advancing to Indicated…

Unico Silver Limited (“USL” or the “Company”) is pleased to report assay results for 21 holes (3587m) as part of an ongoing drill program at the Company’s 100%-owned Joaquin Project in Santa Cruz, Argentina. This includes exceptional high-grade silver gold intercepts at three prospects – La Morocha, La Negra SE and La Morocha SE.

HIGHLIGHTS

• Infill drilling at La Morocha defines the up-dip projection of high-grade mineralisation.

42.4m at 437gpt AgEq (0gpt Au, 437gpt Ag) from 49.6m, including: 1.85m at 8335gpt AgEq (0.2gpt Au, 8313gpt Ag) from 52.7m

• At La Negra SE, drilling has extended mineralisation a further 200m to the southeast, as defined by exploration hole JDD047-25 that returned 34.7m at 110gpt AgEq (0.4gt Au, 69gpt Ag) from 121.5m.
• Significant silver gold assay results from extensional and infill drilling within La Negra SE, include:

Managing Director Todd Williams states:

“The Joaquin Project continues to deliver exceptional results. Infill drilling at La Morocha has confirmed that bonanza-grade silver mineralisation—typical of that previously mined underground by Pan American Silver— extends far closer to surface than previously understood. A standout intercept of 1.8 metres at 8,335gpt AgEq from 52 metres demonstrates the potential for early, near-surface ounces and strengthens the case…
