Titiminas Silver Confirms Historical High-Grade Molybdenum Grades at Janchiscocha in First Modern Exploration Campaign; Defines District-Scale Quartz-Molybdenite Vein System
First-pass underground and surface sampling returns up to 8.29% Mo, confirms multiple newly identified quartz-molybdenite veins across the Janchiscocha and Londres targets and a connecting ~1 km corridor, and defines an approximately 4 km molybdenum trend within Permo-Triassic granitic host rocks.
LIMA, Peru, July 30, 2026 /CNW/ -- Titiminas Silver Inc. (TSXV: TITI) ("Titiminas" or the "Company") is pleased to report results from the first modern exploration campaign at its Janchiscocha molybdenum target, located within the Company's concession block in the Region of Junin, central Peru. Janchiscocha is a past-producing molybdenum mine, with over 2 kilometres of underground development recognized to date. The June 2026 campaign confirmed high-grade molybdenum mineralization at the historically mined Janchiscocha and Londres targets, identified multiple previously untested quartz-molybdenite veins, and recognized a ~1 km mineralized corridor connecting the two historic mines, supporting the Company's interpretation that Janchiscocha hosts a district-scale quartz-molybdenite vein system rather than a series of isolated historic occurrences.
Note on widths: grades are reported over sampling widths (the width of the channel or rock sample taken across the mineralized vein). Geological structure widths, where reported, describe the width of the host structure and are stated separately.
HIGHLIGHTS
- High-grade molybdenum confirmed at both the Janchiscocha and Londres targets, with grades up to 8.29% Mo and consistent average grades in the range of approximately 1 - 2% Mo.
- Janchiscocha mine: systematic underground channel sampling along 150 metres of Level 4464 returned an average grade of 1.33% Mo (including a high assay of 5.08% Mo) over an average sampling width of 0.62 m; sampling along 80 metres of Level 4402 returned an average of 1.01% Mo (peak 1.94% Mo) over an average sampling width of 0.68 m.
- Londres mine: initial underground sampling returned an average grade of 2.30% Mo from eight representative samples, including a maximum assay of 8.29% Mo, over an average sampling width of 0.66 m.
- Multiple new quartz-molybdenite veins discovered across the Janchiscocha mine area, and the Londres mine area and the intermediate corridor, including five previously untested surface veins at Janchiscocha with mapped strike lengths of up to 300 metres and vein widths of 0.4 to 1.0 m.
- ~1 km Janchiscocha - Londres corridor identified, hosting at least four additional quartz-molybdenite structures. The host geological structures reach up to 2.5 m in width and are located approximately 300 metres above the historical underground workings, indicating significant vertical extent.
- District-scale potential: the results define an approximately 4 km mineralized molybdenum trend and support the interpretation of a single larger hydrothermal molybdenum system, consistent with the Cu-Mo porphyry model previously described across the broader Madre Sierra district.
- Critical-metals exposure: molybdenum is classified as a critical mineral in Canada, the United States and the European Union, adding a strategic critical-metals dimension to the Company's silver-focused development.
JANCHISCOCHA MINE
The Janchiscocha mine is the Company's principal molybdenum exploration area, covering approximately 37 hectares. Janchiscocha is a past-producing molybdenum mine, with over 2 kilometres of underground development recognized to date across three levels at the Janchiscocha mine. Exploration completed to date has confirmed a high-grade quartz-molybdenite vein system hosted within Permo-Triassic granitic rocks, a geological environment recognized worldwide for hosting significant molybdenum deposits.
Current work has identified six quartz-molybdenite structures at Janchiscocha, including the historically mined Janchiscocha vein, where underground sampling to-date has confirmed continuous mineralization over 150 metres of strike. In addition to the historical workings, the Company discovered five previously untested quartz-molybdenite veins at surface with mapped strike lengths of up to 300 metres and vein widths ranging from 0.4 metres to 1.2 metres, substantially expanding the known mineralized footprint. The veins occur in multiple structural orientations (N-S, NW-SE and E-W) and are characterized by quartz with molybdenite and associated oxidation minerals, including jarosite, goethite, hematite and locally ferrimolybdite. The mineralization remains open along strike and at depth.
LONDRES TARGET
The Londres target is in the northern portion of the Titiminas property and represents a newly emerging high-grade molybdenum target hosted within the same Permo-Triassic granitic intrusive complex as Janchiscocha. Work to date has identified three quartz-molybdenite veins exposed in historical underground workings, with mapped strike lengths of up to 100 metres and vein widths ranging from 0.3 to 0.9 m, hosted within geological structures up to 0.95 m in width. The mineralization is characterized by coarse molybdenite hosted within quartz veins and remains open along strike and at depth.
Exploration at Londres remains at an early stage, with work to date focused primarily on the historical underground workings; systematic surface mapping and reconnaissance surrounding the mine have yet to be completed. Management believes this provides meaningful exploration upside and the potential to identify additional mineralized structures within the broader target area.
JANCHISCOCHA - LONDRES CORRIDOR
One of the most significant outcomes of the campaign is the recognition of a previously unknown mineralized corridor extending approximately 1 kilometre between the Janchiscocha and Londres mines. Within this corridor, the exploration team identified at least four additional quartz-molybdenite veins associated with historical underground workings, exhibiting mapped strike lengths of 30 metres to 100 metres. The host geological structures reach up to 2.5 metres in width, with mineralized sampling widths of up to 0.8 metres.
The geological, structural and mineralogical characteristics of these veins closely resemble those at both Janchiscocha and Londres. The newly identified structures occur approximately 300 metres above the historical underground workings, highlighting significant vertical exploration potential and indicating that the mineralizing system may extend over a substantial elevation range. This continuity supports the interpretation that the two historic mines form part of a single larger hydrothermal molybdenum system.
ADDITIONAL VEIN POTENTIAL ACROSS THE TARGETS
Beyond the principal structures sampled during the campaign, each of the targets hosts multiple additional mineralized veins mapped at surface and in underground workings, providing a substantial inventory of priority targets for follow-up work:
- Janchiscocha target: in addition to the six principal quartz-molybdenite structures, a further dozen mineralized veins have been mapped at surface.
- Londres target: in addition to the three principal veins developed by historical workings, a further half-dozen veins have been observed at surface.
- Janchiscocha - Londres corridor: in addition to the four principal structures, a further four veins have been revealed in the surrounding area.
Collectively, these additional veins reinforce the interpretation of an extensive, district-scale quartz-molybdenite system and materially expand the pipeline of drill-ready targets. Geological work will continue at Janchiscocha over the coming months, with the aim of reaching a strategic decision on the target by year end.
GEOCHEMICAL RESULTS
The first phase of the geochemical program comprised 100 rock samples (89 underground and 11 surface), collected from the Janchiscocha and Londres targets and analyzed by Certimin S.A. Laboratory in Lima, Peru. A summary of principal results is presented below.

The consistently high molybdenum grades returned from both Janchiscocha and Londres support the Company's interpretation that the target area hosts a district-scale quartz-molybdenite vein system and justify advancing to the next phase of systematic exploration, including detailed mapping, channel sampling and drill testing.
DISTRICT-SCALE INTERPRETATION
The results substantially expand the known mineralized footprint through the discovery of multiple previously unrecognized quartz-molybdenite veins at Janchiscocha, at Londres, and within the corridor between the two targets. The identification of several mineralized structures with consistent geological and mineralogical characteristics supports the interpretation that Janchiscocha and Londres may represent parts of a larger, district-scale hydrothermal molybdenum system rather than isolated mineral occurrences.
This interpretation is consistent with the integrated geological model previously described for the broader Madre Sierra district, in which high-grade molybdenum and potassic alteration at Janchiscocha represent the proximal expression of a Cu-Mo porphyry system at depth. Historical underground development, recent high-grade sampling results and newly identified surface mineralization together provide multiple priority targets for the next phase of systematic exploration, including detailed mapping, channel sampling and diamond drilling.
COMMENTARY FROM THE VP OF EXPLORATION
"These are exactly the results we hoped to see from a first, disciplined sampling program at the Janchiscocha molybdenum mine. High-grade molybdenum is confirmed not only in the historically mined workings but across five previously untested surface veins and a full kilometre of new ground between Janchiscocha and Londres - pointing to a single, district-scale quartz-molybdenite system rather than isolated historic mines. The newly recognized structures also sit roughly 300 metres above the old workings, consistent with the Cu-Mo porphyry model we have described for the broader Madre Sierra district.
Our next step is to convert this sampling into a systematic mapping, channel-sampling and drill-testing program to define the scale of the system. With molybdenum now recognized as a critical metal across our core markets, Janchiscocha adds a meaningful critical-metals dimension to our silver-focused pipeline," said Helmut Herrera, VP of Exploration of Titiminas Silver Inc.
