Titiminas Silver Reports High-Grade Mineralization from First Channel Sampling Program and Identifies New Mineralized Episodes at the Madre Sierra Project, Peru
New high-grade Ag–Cu–Au vein system north of
In parallel, the Company has identified a new mineralization episode immediately north of the Madre Sierra mine, herein referred to as the
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 theNorth 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†.

Decline 4633 – Underground Continuation (~40 m down-dip)
Underground channel sampling along decline 4633, which extends approximately 40 m down-dip from Trench 4633, has confirmed the continuity of high-grade Ag–Pb–Zn CRD mineralization. Highlight samples include 0.60 m @ 14.85 oz/t Ag, 19.55% Pb and 30.00% Zn† (sample 6982), 0.80 m @ 28.55 oz/t Ag and 30.00% Pb† (sample 6986), and 1.50 m @ 15.03% Pb and 30.00% Zn† (sample 6980).

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
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
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 /
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

The technical and scientific information contained in this news release has been reviewed and approved by
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.
