Meridian Drills Further High-Grade Au-Cu-Ag & Zn Mineralization at Santa Helena and Opens New Gold Exploration Frontier at Santa Fe

Executive Summary

• Meridian reported multiple high‑grade Au‑Cu‑Ag‑Zn intersections from its Santa Helena infill program, highlighted by CD‑727 (15.2 m @ 7.4 g/t AuEq) and several >10 g/t AuEq intervals.
• A first reconnaissance program at the Santa Fé target intersected gold in the Aguapei Formation (up to 1.5 g/t Au), opening a new green‑field exploration frontier within the Cabaçal belt.
• Regional drilling commenced at the Cigarra Cu‑Au prospect and additional chargeability anomalies were identified north of Santa Helena, with pending assay results.

Key Details

• Santa Helena drill highlights (selected holes):
• CD‑749: 6.1 m @ 10.5 g/t AuEq (7.1 % CuEq)
• CD‑742: 7.6 m @ 6.9 g/t AuEq (4.6 % CuEq); includes 2.6 m @ 10.5 g/t AuEq (7.0 % CuEq)
• CD‑735: 9.6 m @ 5.8 g/t AuEq (3.9 % CuEq); includes 5.7 m @ 8.8 g/t AuEq (5.9 % CuEq)
• CD‑727: 15.2 m @ 7.4 g/t AuEq (4.9 % CuEq); includes 10.4 m @ 9.4 g/t AuEq (6.3 % CuEq) – >100 gram‑metre interval
• CD‑719: 8.4 m @ 10.2 g/t AuEq (6.8 % CuEq); includes 5.0 m @ 14.4 g/t AuEq (9.7 % CuEq)

• CD‑715: 14.6 m @ 5.7 g/t AuEq (3.8 % CuEq); includes 9.2 m @ 7.4 g/t AuEq (5.0 % CuEq)

• True width assumption: 85–95 % of down‑hole widths.

• Aguapei Formation (Santa Fé) channel samples:

• CA_CN_028: 1.52 g/t Au, 0.09 % Zn
• CA_CN_029: 0.22 g/t Au, 0.35 % Zn

• CA_CN_030–032: Au ≤ 0.45 g/t, Zn ≤ 0.09 %

• Exploration implications of Aguapei: potential deeper greenstone targets, undiscovered gold‑bearing basement, possible placer gold concentration.

• Santa Helena North update:

• New chargeability anomaly “Santa Helena Far North” (0.5 km strike).
• Drill CD‑767 completed over the original anomaly – assays pending.

• Drill CD‑762 intersected trace Au (144 ppb over 1 m) and minor base metals (3.2 m @ 0.16 % Zn, 3.3 m @ 0.19 % Cu).

• Regional reconnaissance:

• Hole CD‑765 (86 m depth) intersected deep Aguapei cover; terminated in gabbroic footwall similar to Santa Helena footwall.

• Another hole hit a gabbro unit near a gravity anomaly, suggesting a basement high.

• Cigarra Cu‑Au prospect: drilling initiated; detailed results forthcoming.

• Technical notes: Samples analyzed at ALS (Lima) using fire assay with AAS finish for Au, gravimetric finish for >10 g/t Au, and ICP methods for base metals. QA/QC includes blanks, standards, and ~5 % umpire re‑analysis.

• Qualified Person: Erich Marques, B.Sc., FAIG (Chief Geologist).

“Today's results are confirming that significant and near‑surface extensions of open mineralization extend out from the historical Santa Helena mine… The Aguapei Formation is a prodigious gold host for the Alto Guaporé gold province to the west.” – Gilbert Clark, CEO
