Platauro Metals outlines exploration and development strategy

Company to Advance Drill Permitting at Princesa, Update Las Minas Economics, and Unlock District-Scale Potential at the Star Project

Vancouver, British Columbia--(Newsfile Corp. - August 12, 2026) - Platauro Metals Corp. (TSXV: PURO) (OTCQB: MEXGF) (" Platauro " or the " Company ") is pleased to outline its strategic exploration and development priorities for the second half of 2026 as it advances its portfolio of precious metals projects across Peru, Mexico, and the United States.

Following the successful combination of Mexican Gold and Alcon Silver, Platauro has established a disciplined strategy focused on advancing its flagship Princesa (Peru) and Las Minas (Mexico) projects while systematically evaluating the district-scale exploration potential of the Star Project in Utah. The Company's 2026 work program is designed to de-risk its core assets, enhance project economics, and generate high-impact exploration targets that position Platauro for long-term value creation.

2026 Strategic Priorities

Advancing Drill Permitting at the Princesa Silver Project

The Company's primary objective at the Princesa Project is to complete all permitting required for a comprehensive drill program designed to validate and expand the project's historical mineral resource. The planned drilling will focus on confirming historical results, testing areas excluded from previous resource estimates, and evaluating extensions along the mineralized breccia system.

Princesa hosts a partially delineated historical silver-lead-zinc resource with considerable expansion potential. Historic drilling tested only a portion of the known mineralized system, providing the Company with multiple opportunities to increase both the size and confidence of the resource. Completion of the permitting process will position the Company to commence drilling upon receipt of necessary approvals.

Updating the Las Minas Geological Model and Project Economics

At Las Minas, the Company intends to undertake a comprehensive review of the project's geological interpretation which will incorporate the recently acquired Tatatila claims. Since completion of the 2021 Preliminary Economic Assessment, favourable increases in precious metals prices and the latest technical information for iron-oxide copper gold (IOCG) skarn systems present an opportunity to reassess the project's development potential. Platauro will re-examine its mineral resource model and update its economic studies to reflect current metal prices and cost assumptions.

Advancing District-Scale Exploration at the Star Project

Platauro will also advance compilation and interpretation of the Star Project data, assembling historical geological and geophysical data into a modern digital exploration database. The objective is to develop an updated district-scale geological model capable of generating high-quality exploration targets for future field programs.

Work will focus on identifying previously overlooked mineralized trends, integrating historical datasets with modern interpretation techniques, and evaluating the broader potential of the district. The Company believes this systematic approach provides a cost effective pathway toward identifying drill-ready targets while maximizing the value of historical exploration expenditures.

Building a Pipeline of Growth Opportunities

Collectively, these initiatives are designed to strengthen the Company's portfolio by advancing near-term development opportunities while creating multiple catalysts for future discovery.

" Our strategy for 2026 is focused on disciplined technical advancement across each of our core assets ," said Jack Campbell, Chief Executive Officer and Chairman of Platauro. " At Princesa, our priority is securing drill permits that will allow us to validate and grow the historical silver system through a comprehensive drill program. At Las Minas, we see significant value in updating the geological model and project economics to reflect today's metal price environment and our improved understanding of the deposit. At the Star Project, we have an opportunity to unlock value through systematic compilation and modern interpretation of an underexplored district .

" Together, these initiatives establish multiple catalysts for shareholders while maintaining a capital-efficient approach to exploration. We believe this strategy positions Platauro to create value through both resource growth and technical advancement as we continue building a diversified precious metals exploration company. "
