Tier One Silver Extends Community Partnership at Curibaya and Prepares for Next Phase of Drilling and Exploration

On December 16, 2025, Tier One Silver Inc. announced the extension of its social access agreement with the Chipispaya community, which grants access to the Curibaya project in Peru. This renewed agreement is effective through June 11, 2026, with an option for further extension upon community assembly approval. The company reaffirmed its commitment to local employment and training initiatives as part of this partnership.

With the social access secured, Tier One Silver is now preparing for its next drill campaign, scheduled to commence in Q1 2026. This campaign will focus on expanding high-priority silver-gold targets, specifically in the Cambaya area, which has not been previously drilled. The 17,000-hectare Curibaya project is noted to host six distinct high-grade silver-gold mineralized corridors and a copper porphyry target.

This news is positive but routine, as it primarily confirms the company's ability to continue its planned exploration activities. The social access agreement is a fundamental prerequisite for any mining exploration in the region, and its renewal ensures operational continuity. The CEO's statement highlights the company's commitment to responsible advancement and the "significant high-grade silver-gold and copper potential" at Cambaya, which remains undrilled.

The preparation for a Q1 2026 drill campaign is in line with previous expectations, as the June 9, 2025 news release also mentioned a target drill program timing of Q3 2025 (subject to financing). The subsequent September 2025 financing ($6.5 million) provided the necessary capital, and this latest update confirms the timeline for deployment of those funds into exploration. The fact that the Cambaya corridors have "never been drilled" presents genuine exploration upside, but the current news is an enabling step rather than a discovery. The market impact is likely to be neutral to slightly positive, as it de-risks a key operational aspect and keeps the pipeline for future catalysts active.

Tier One Silver Inc. is a Canadian-based precious metals exploration company focused on high-grade silver, gold, and copper opportunities in Peru. Its flagship project is Curibaya, an approximately 17,000-hectare property located in southern Peru, within a prolific copper porphyry belt. The project is described as hosting six distinct high-grade silver-gold mineralized corridors and a compelling porphyry copper target. The company has highlighted that only a fraction of the property has been explored. Surface sampling at the Cambaya area has previously yielded high-grade results (e.g., 0.5 meter of 9,280.4 g/t silver equivalent).

The company's mineral property interests, specifically the Sambalay and Salvador concessions within Curibaya, are subject to royalties. Sambalay is subject to a 1.5% net smelter return (NSR) royalty, and Salvador is subject to a 2.0% NSR royalty. Additionally, the Salvador concessions require a US$2.0 million production payment at the time a production decision is made. These royalties and payments will impact future profitability if the project reaches production.
