Titiminas Silver Commences Drill Program at the Madre Sierra Silver Mine, Peru

4,000-metre Packsack underground program underway concurrent with 15,500-metre HQ diamond drill program

LIMA, Peru, June 8, 2026 /CNW/ - Titiminas Silver Inc. (TSXV: TITI) ("Titiminas" or the "Company") is pleased to announce the commencement of its drill program at the Madre Sierra Silver mine in the Ricran District, Jauja Province, Region of Junín, 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 ~5 km mineralized corridor, and to support the completion of a maiden NI 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 the 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 testwork 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 ~5 km 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 Ag-Cu-Au vein system confirmed within historical underground workings at ~4,470 m a.s.l., with high-grade channel samples including 0.40 m @ 73.99 oz/t Ag, 0.40 m @ 14.53% Cu and 0.40 m @ 18.92 g/t Au, 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 1km of existing underground development, which returned 8.20 m @ 7.69 oz/t Ag, 10.18% Pb and 18.46% Zn from channel sampling at the Chambará 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 CEO

"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 multi-target mineral system."
