• Well-funded with C$12 million in treasury and strong shareholder support, including over 35% insider ownership.

Metates project overview and economics

• One of the world's largest undeveloped gold-silver deposits, with 921Mt M&I resources (16.8Moz Au, 423Moz Ag) and 140Mt inferred (2.1Moz Au, 59Moz Ag).

• 2021 PEA outlines a 15ktpd sulphide heap leach starter project, expandable, with 31-year mine life and initial capex of US$359M.

• Average annual production (years 1–15): 112Koz gold, 2.5Moz silver; LOM cash costs US$686/oz Au, AISC US$749/oz Au.

• Pre-tax NPV (5%) of US$1.14B and IRR of 35% at $1,600/oz gold and $22/oz silver; project highly sensitive to metal prices.

• Heap leach approach reduces capex by ~90% versus 2016 PFS and lowers environmental footprint.

Proprietary oxidative leach technology

• Enables gold recovery rates exceeding 70% from refractory sulphide ores, with up to 74% achieved in 2024 testwork.

• Technology reduces water, energy, and GHG emissions compared to autoclave processing, supporting "Green Gold" production.

• Over $50M invested in R&D; IP protected by patents; commercialization underway with third-party projects.
