TITIMINAS SILVER COMMENCES DRILL PROGRAM AT THE MADRE SIERRA SILVER MINE, PERU

Titiminas Silver Inc. has commenced its drill program at the Madre Sierra silver mine in the Ricran district in Jauja province, region of Junin, central Peru. The program is designed to systematically test high-grade mineralization across the Madre Sierra, Madre Sierra Norte and Titiminas CRD target zones that define the company's approximately five-kilometre mineralized corridor and to support the completion of a maiden National Instrument 43-101 mineral resource estimate targeted for Q2/Q3 2027.

Highlights:

• Packsack underground diamond drilling has commenced;
• 4,000-metre packsack underground program to be drilled over 12 months across existing underground workings at the Madre Sierra mine, concurrently with -- and designed to complement -- the subsequent HQ core drill program;
• 15,500-metre HQ underground core drill program targeting Madre Sierra, Madre Sierra Norte and Titiminas CRD;
• Underground HQ core drilling focused on the area of the historical resource at Madre Sierra and two newly confirmed adjacent deposits -- Madre Sierra Norte and Titiminas CRD;
• GC Drillers EIRL contracted for both phases;
• Maiden NI 43-101 mineral resource estimate targeted Q2/Q3 2027;
• Drill results from both phases, together with metallurgical test work and basic engineering studies, are intended to also support a preliminary economic assessment (PEA) and final investment decision (FID) targeted for Q4 2027.

Phase 1 -- packsack underground diamond drilling

The company has mobilized two packsack drill rigs within the existing underground workings at the Madre Sierra silver mine. Packsack drilling is a compact, man-portable underground technique well suited to the Madre Sierra mine configuration, enabling the company to drill from multiple underground platforms within the existing workings.

The packsack program totals 4,000 metres and is expected to run for approximately 12 months, targeting various vein structures within the mine workings that returned the highest-grade results from the company's prior systematic channel sampling program. Results will be released on a rolling basis as assays are received and will inform drill collar locations and target priorities for the HQ core drill program running concurrently.

Phase 2 -- 15,500-metre diamond drill program

Running concurrently with the packsack program, the company will advance its 15,500-metre HQ underground core drill program. Drilling will be conducted from underground platforms within the Madre Sierra mine workings and will focus on three principal target zones across the company's approximately five-kilometre mineralized corridor:

• Madre Sierra -- the primary target zone and the focus of the company's resource delineation program: Madre Sierra hosts a historical underground resource and has been mined on a small-scale basis; the HQ drill program is designed to provide the modern, NI 43-101-compliant data necessary to convert historical resource estimates into a current mineral resource estimate.
• Madre Sierra Norte (North zone) -- a newly identified silver-copper-gold vein system confirmed within historical underground workings at approximately 4,470 metres above sea level, with high-grade channel samples including 0.40 metre at 73.99 ounces per ton silver, 0.40 metre at 14.53 per cent copper and 0.40 metre at 18.92 grams per tonne gold, as reported in the company's April 29, 2026, news release titled "Titiminas Silver Reports High-Grade Mineralization from First Channel Sampling Program and Identifies New Mineralized Episodes at the Madre Sierra Project, Peru."
• Titiminas CRD -- a past-producing carbonate replacement deposit with over one kilometre of existing underground development: This deposit returned 8.20 metres at 7.69 ounces per ton silver, 10.18 per cent lead and 18.46 per cent zinc from channel sampling at the Chambara limestone-dacite contact, as reported in the company's April 29, 2026, news release.

The 15,500-metre program has been designed to generate sufficient data to support the preparation of a maiden NI 43-101 mineral resource estimate targeted for Q2/Q3 2027. The company plans to provide regular updates as drilling progresses and assay results become available.

Commentary from the chief executive officer

"The start of drilling at Madre Sierra marks a defining milestone for Titiminas. We have two programs running simultaneously: a 4,000-metre packsack program within the existing underground workings and a 15,500-metre HQ core drill program that will systematically test our three target zones. Together, they are designed to deliver a maiden resource estimate and put us firmly on the path to a final investment decision by end of 2027. We have the right contractor, the right community relationships and a multitarget mineral system," stated Luis Goyzueta, chairman and chief executive officer of Titiminas Silver.

About Titiminas Silver Inc.

Titiminas Silver is a Peru-focused silver developer advancing the high-grade, past-producing Madre Sierra silver mine in the Ricran district in Jauja province, region of Junin, central Peru. The company holds an option to acquire 100 per cent of Compania Minera Rosalinda SAC, which holds 18 mining rights covering 7,561 hectares. The company is pursuing a phased development strategy designed to fast-track production at Madre Sierra under Peru's small-mining regime while concurrently expanding exploration across the broader district, including the Madre Sierra Norte, Titiminas CRD and Janchiscocha targets that define an approximately five-kilometre mineralized corridor with potential to host a large-scale copper-molybdenum porphyry system at depth.
