New high-grade Ag–Cu–Au vein system north of Madre Sierra, confirmation of CRD-style Ag–Pb–Zn mineralization in a past producing mine, and a 5 km contact zone vectoring toward a large-scale Cu–Mo porphyry target
LIMA, Peru, April 29, 2026 /CNW/ - Titiminas Silver Inc. (TSXV: TITI) ("Titiminas" or the "Company") is pleased to provide an update on its flagship Madre Sierra Project in central Peru. The Company's geological team has confirmed high-grade Ag–Pb–Zn mineralization at the past-producing Titiminas CRD, a Carbonate Replacement Deposit-style system with over 500 m of existing underground development located within the Madre Sierra concession block. Surface and underground channel sampling have validated the continuity and tenor of mineralization at the Titiminas CRD, which the Company intends to incorporate into the planned drill program and into the design of a potential future mining operation alongside Madre Sierra.
In parallel, the Company has identified a new mineralization episode immediately north of the Madre Sierra mine, herein referred to as the Madre Sierra Norte (North Zone). This newly recognized Ag–Cu–Au vein system is exposed at surface and within historical underground workings and, together with the Titiminas CRD and the Janchiscocha porphyry target to the north, defines a ~5 km contact zone with significant expansion potential and clear vectoring toward a large-scale Cu–Mo porphyry target.
HIGHLIGHTS
- The Titiminas CRD is a past-producing high-grade mine with over 500 m of existing underground development; the Company's geological team is reviewing historical records and, given its proximity to Madre Sierra, the Titiminas CRD will be incorporated into the planned drill program and potential future mining operation.
- High-grade CRD-style mineralization confirmed: a single 8.20 m channel-sampled trench (Trench 4633) returned 8.20 m @ 7.69 oz/t Ag, 10.18% Pb and 18.46% Zn at the Chambará limestone–dacite contact.
- Madre Sierra Norte – A new Ag–Cu–Au vein system identified in the North Zone at ~4,470 m a.s.l., with surface and underground exposure across 10 distinct structures.
- Increasing thickness and grade at depth
:at the lower elevation of the valley (~4,315 m a.s.l.), a 7 m wide geological structure hosts a ~1.3 m true thickness mineralized zone grading 0.2 g/t Au, 9.97 oz/t Ag, 5.39% Cu, 0.49% Pb, and 0.01% Zn. - High-grade underground channel samples in the Madre Sierra Norte (North Zone) vein system over two mine levels (~250 m of workings), including 0.40 m @ 73.99 oz/t Ag; 0.40 m @ 14.53% Cu; 0.40 m @ 18.92 g/t Au.
- Evidence of an integrated porphyry CRD–epithermal system, comprising CRD-style mineralization at Titiminas CRD and epithermal vein systems at Madre Sierra and Madre Sierra Norte, supported by zoned alteration (potassic and propylitic) and a high-grade molybdenum association at the Janchiscocha target.
TITIMINAS CRD – CHAMBARÁ LIMESTONE–DACITE CONTACT
Approximately 700 m east of the Madre Sierra veins, the Company has identified a Carbonate Replacement Deposit (CRD) style system, herein referred to as the Titiminas CRD, developed at the contact between the Chambará limestone and the Madre Sierra dacite stock. The contact is traceable along approximately 5 km of strike, defining a major exploration corridor.
The Titiminas CRD is also a past-producing high-grade silver-lead-zinc mine with over 500 m of existing underground development, providing direct access to the mineralized horizon at multiple elevations. The Company's geological team is currently reviewing historical mine documentation, sections, metallurgical records and underground sampling data to fully integrate this asset into its development pipeline. Given the proximity of the Titiminas CRD to Madre Sierra and the demonstrated continuity of high-grade Ag–Pb–Zn mineralization, the Company intends to incorporate the Titiminas CRD into the planned drill program and into the design of a future potential mining operation alongside Madre Sierra, materially expanding the project's near-term production potential.
- Surface widths of mineralized stratigraphy of up to ~8.2 m.
- Over 500 m of existing underground development on the past-producing Titiminas CRD at the ~4,280 m a.s.l. level.
- At the 4,633 m a.s.l. level, underground development on mineralized ore extends ~40 m down-dip from Trench 4633 (grades shown in the Decline 4633 table below).
- Economic Ag–Pb–Zn grades confirmed by surface and underground channel sampling.
Trench 4633 – Single 8.20 m Continuous Channel
Trench 4633 is a single 8.20 m long continuous channel-sampled trench representing the true thickness of one mineralized horizon at the limestone–dacite contact. Nine channel samples were collected sequentially along the trench. The length-weighted average grade across the full 8.20 m is 7.69 oz/t Ag, 10.18% Pb and 18.46% Zn, with peak intervals of 1.20 m @ 12.50 oz/t Ag and 1.30 m @ 30.00% Zn†.

NEW MINERALIZATION EPISODE – MADRE SIERRA NORTE / NORTH ZONE (AG–CU–AU)
A new mineralization episode has been identified in Madre Sierra Norte (North Zone), located immediately north of the Madre Sierra mine. The episode is associated with multiple Ag–Cu–Au-bearing quartz veins located at approximately 4,470 m a.s.l., exposed both at surface and within historical underground workings.
- Average vein widths of ~0.50 m at 4,470 m a.s.l.
- True width increases to ~1.3 m average at 4,315 m a.s.l. within a 7 m wide geological structure.
- Tensional vein geometries indicative of a dilatant structural setting.
- High silver, copper and gold content.
Surface Channel Sampling – Madre Sierra Norte / North Zone Veins
Surface channel samples and an ore stockpile sample from the new Ag–Cu–Au vein system are presented below. Highlight intervals include 0.45 m @ 9.29 g/t Au, 13.60 oz/t Ag, 1.74% Cu, 9.67% Pb and 1.85% Zn (sample 40056), and an ore stockpile sample grading 40.68 oz/t Ag (sample 40036).

INTEGRATED GEOLOGICAL MODEL
The work to date supports an integrated, multi-episodic mineralizing system at Madre Sierra, comprising:
- CRD-style Ag–Pb–Zn replacement bodies at the Chambará limestone–dacite contact (distal expression);
- Polymetallic Ag–Pb–Zn and Ag–Cu–Au veins hosted in the dacite stock (intermediate expression);
- A potential Cu–Mo porphyry system at depth, vectored by potassic alteration and high-grade molybdenum at the Janchiscocha target (proximal expression).
This vertical and lateral metal zonation is consistent with classic Cordilleran polymetallic districts of central and southern Peru.
COMMENTARY FROM THE VP OF EXPLORATION
"These results confirm what the geology has been telling us since we began systematic work on the property: Madre Sierra is a fully integrated, multi-episodic mineral system. The combination of high-grade CRD-style Ag–Pb–Zn mineralization at the limestone–dacite contact, a brand-new Ag–Cu–Au vein system in Madre Sierra Norte (North Zone), and the potassic–propylitic alteration footprint at Janchiscocha are textbook elements of a Cordilleran polymetallic district with porphyry roots.
What is particularly compelling is the metal zonation we are now seeing across the property: silver-rich polymetallic veins (Ag–Au–Cu + Pb–Zn at Madre Sierra), quartz veins (Ag–Cu–Au at Madre Sierra Norte / North Zone), the carbonate contact (Ag–Zn–Pb at Titiminas CRD), and the hydrothermal alteration evidence (potassic and propylitic) indicate the location of a Cu–Mo porphyry target at depth. In my experience exploring porphyry and epithermal cordilleran systems in Peru and Chile, this is exactly the architecture you want to see when vectoring toward a large-scale Cu–Mo discovery at depth.
With a ~5 km contact zone now defined, we have a multi-target pipeline that will support a robust resource delineation drill program and create meaningful news flow for shareholders over the coming quarters," said Helmut Herrera, VP of Exploration of Titiminas Silver Inc.

QUALITY ASSURANCE / QUALITY CONTROL
Channel samples reported herein were collected by Titiminas geologists under standard protocols, sealed on site and submitted to an accredited independent laboratory for preparation and assay. Gold was determined by fire assay with an atomic absorption finish and silver, copper, lead and zinc by multi-element ICP analysis with over-limit samples re-assayed by appropriate higher-range procedures. Certified reference materials, blanks and field duplicates were inserted into the sample stream. Selected over-limit results for lead and zinc reported in this release reflect the upper detection limit of the primary method and are subject to re-analysis.
