Briefing
Inferred Mineral Resources must not be included in the economic analysis, production schedules, or estimated mine life in publicly disclosed Pre-Feasibility or Feasibility Studies, or in the Life of Mine plans and cash flow models of developed mines. Key points: Inferred Mineral Resources must not be included in the economic analysis, production schedules, or estimated mine life in publicly disclosed Pre-Feasibility or Feasibility Studies, or in the Life of Mine plans and cash f; The structurally-controlled higher-grade mineralization, while potentially beneficial to early cash flow or NPV, represents a subordinate and higher-risk component due to limited tonnage, discontinuity, and reduced geolo; As a result, the QP has elected to summarize only that drilling contained within the Property boundary and used for Mineral Resource estimation purposes, which includes a total of 192,895 m in 1,782 drill holes; No detailed annual average grades for the historical production are available for the last production period of the mine, under Compañía Minera Dayton (between 2015 and 2018); however, the recorded production data indica; The CMD exploration and mineral resource drilling culminated in a feasibility study undertaken by Bechtel on behalf of CMD in 1994; The results from the Umpire Laboratory testing show acceptable repeatability as 70% of the paired data plotted within the generally accepted 20% HARD precision limits for samples greater than 0.15 g/t Au. This brief is based on the cited source artifact and is intended as a research entry point, not a replacement for the original source or EGM canonical data tables.

Revision 0 Effective Date: February 1, 2026 Report Date: May 4, 2026 DRA Ref.: C10138-0000-PM-REP-0001-Rev. 0 IMPORTANT NOTICE This Report, following National Instrument 43-101 rules and guidelines, was prepared for Galantas Gold Corporation (Galantas or the Company) by DRA Americas Inc. (DRA). The quality of information, conclusions and estimates contained herein is consistent with the level of effort involved in DRA services, based on: i) Information available at the time of preparation, ii) Data supplied by outside sources, and iii) The assumptions, conditions, and qualifications set forth in this Report. This Technical Report contains estimates, projections and conclusions that are forward-looking information within the meaning of applicable laws. Forward-looking statements are based upon the responsible Qualified Person’s (QP’s) opinion at the time they are made but, in most cases, involve significant risks and uncertainty. Although each of the responsible QPs has attempted to identify factors that could cause actual events or results to differ materially from those described in this Report, there may be other factors that could cause events or results to not be as anticipated, estimated or projected. There can be no assurance that forward-looking information in this Report will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements or information. Accordingly, readers should not place undue reliance on forward-looking information.
