Titan Mining Corporation (NYSE-A:TII) (TSX:TI), an existing zinc concentrate producer in upstate New York and the only end to end producer of natural flake graphite in the U.S., today provided an update on its germanium (Ge) evaluation program at its 100%-owned Empire State Mines property. A property-wide reconnaissance program has confirmed elevated germanium across the Balmat-Edwards mineral system, in both primary zinc ore and historic tailings, establishing district-wide enrichment as a characteristic of the system rather than a localized occurrence.

HIGHLIGHTS

• District-Wide Enrichment Confirmed: sampling across six underground ore bodies and two historic tailings facilities confirmed elevated germanium across the Balmat-Edwards zinc system.
• Priority Targets Identified:
  • 18.8 million short tons (internal engineering estimate) at Number 4 tailings, with five samples ranging from 18.1 to 31.3 ppm
  • 4.97 million short tons (based on historical mill production records) at Edwards tailings facility, with two samples ranging from 30.1 to 44.7 ppm
  • 600,000 short tons in the current mineral resource estimate at Mud Pond Main, with three samples ranging from 4.5 to 85.6 ppm
• Enrichment Confirmed Across All Sampled Zones: individual characterization sample results by zone are summarized below (see Tables 1 and 2 and accompanying notes):

• Current Germanium Prices: approximately US$6,000/kg (US$6/g; 1 ppm = 1 g/t), with demand expected to benefit from growth in semiconductor, AI, defense and fiber optic technologies.

“As North America continues to prioritize secure domestic sources of critical minerals, we’re well positioned to play an important role in that supply chain,” said Rita Adiani, President and CEO of Titan Mining. “These results confirm that germanium is a district-wide characteristic of the mineral system at Empire State Mines, not a localized occurrence. We are seeing consistent germanium tenor across multiple historic tailings facilities and meaningful values in primary ore. That breadth is why we are concentrating the next phase of work on two targets, Mud Pond Main, and Edwards, which is among the larger tailings facilities on the property. Current strong germanium pricing, with landed US pricing at over $6,000/kg, creates an incentive for detailed investigation into these areas.”

PROGRAM OVERVIEW

The Company has completed a targeted characterization sampling program across six underground ore bodies within the Empire State Mines zinc Mineral Resource Estimate to evaluate the potential for germanium as a recoverable by-product element. Three samples were collected from within the defined mineralized domain of each ore body and analyzed for germanium. Additionally, five samples were collected by auger sampling of the upper horizon of the Number 4 Tailings, and two auger samples were collected from the upper horizons of the Edwards Tailings.

Table 1 summarizes germanium assay results by ore body. Table 2 summarizes germanium assay results from the Company’s historic tailings facilities.

Table 1: Zinc Mineral Resource Estimate and Germanium Assay Results by Ore Body

1) Zinc Mineral Resource Estimates are sourced from the Empire State Mines NI 43-101 Technical Report, effective December 1, 2025, prepared by Donald R. Taylor, MSc., PG, SME Registered Member #4029597. Mr. Taylor is a director of the Company and is not independent of the Company within the meaning of NI 43-101. Tonnages are reported in US short tons, rounded to the nearest hundred short tons. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Inferred Mineral Resources are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that Inferred Mineral Resources will be converted to Measured or Indicated categories through continued exploration.

2) Germanium values represent individual assay results from characterization samples collected within the defined mineralized domain of each ore body. Samples were analyzed using the method described in the Quality Assurance and Quality Control section of this release. These values are exploratory in nature and do not constitute a mineral resource estimate for germanium. There has been insufficient sampling to define a representative germanium grade for any ore body, and these results must not be applied to any resource tonnage to derive a contained metal quantity. It is uncertain whether further exploration will result in germanium being delineated as a mineral resource or recoverable as an economic by-product credit. Germanium assay results have been reviewed and approved by Matthew Melnyk, CPG #11540, Titan’s VP Geology and Exploration, a Qualified Person as defined by NI43-101. Mr. Melnyk is not independent of the Company within the meaning of NI 43-101 and has not reviewed or approved any mineral resource estimate referenced herein.

3) Tailings tonnage figures are internal engineering estimates only. They have not been verified by drilling, bulk density testing, or formal resource estimation and do not constitute mineral resources under NI 43-101 or any other reporting standard. The Number 4 Tails tonnage is derived from Kilbourne project engineering studies. The Edwards Tails tonnage is derived from historical mill production records.

4) Edwards Tails: Two samples collected. Results should not be interpreted as representative of the full tailings facility.

NEXT STEPS IN THE GERMANIUM PROGRAM

Having now confirmed germanium across multiple ore bodies and tailings facilities, the Company’s germanium program advances to:

1. Prioritization, based on existing data and running concurrently with deportment studies to focus resources on bodies and process streams showing the strongest germanium values.
2. Mineral deportment and mineralogical studies, to identify the specific host mineral phases for germanium within respective settings.
3. Recovery test work, to evaluate processing options best suited to the mineralogy of the host mineral phase, with continued evaluation of scavenger and pre-float tailings streams progressing in parallel under the Teck cooperation agreement announced May 13, 2026.

Deportment and mineralogical studies are underway to determine the most capital-efficient recovery pathway. The Company expects to provide further updates on the program as results from this work become available.

Quality Assurance and Quality Control

Samples were collected by Empire State Mines’ personnel following documented chain of custody procedures and submitted to ALS, an accredited independent laboratory, for analysis. Germanium and multi-element contents were determined by sodium peroxide fusion with an inductively coupled plasma mass spectrometry (ICP-MS) finish (method ME-MS89L), with a rare earth element package added to the analytical suite. ALS inserted certified reference materials (AMIS0341, AMIS0684, GTA-05, OREAS 146, and SY-5 for SD26171672; AMIS0341, AMIS0684, and SY-5 for SD26193076), blanks, and pulp duplicates as part of its standard laboratory QC program. All reference materials returned values within certified acceptance limits for germanium, with the exception of OREAS 146 in batch SD26171672, which returned germanium below the detection limit against a certified range of 4.6–7.2 ppm. Given the REE-concentrate matrix of OREAS 146 and the consistent performance of the remaining four reference standards, the Company considers this result to reflect a matrix-compatibility limitation of that standard rather than an analytical error. Blanks returned no detectable germanium contamination. Pulp duplicates showed excellent reproducibility for germanium, with relative percent differences of 2.6%, 5.8%, and 1.2%, respectively. The Company did not insert project level certified reference materials or blanks external to the laboratory submission. The Company has not identified any QC failures that would affect confidence in the germanium analytical data.

The Qualified Person has reviewed the sampling procedures, chain of custody documentation, laboratory certificates, and QC data summarized above and is satisfied that the sampling and analytical procedures are appropriate for the style of mineralization and the purpose of this characterization program. The primary limitation of the dataset is sample population size. Three samples per underground ore body, two samples from the Edwards Tailings and five samples from the Number 4 Tailings are sufficient to confirm the presence and approximate tenor of germanium enrichment within individual samples but are insufficient to define grade continuity, establish representative average grades or support mineral resource estimation.

Germanium determination requires a closed-vessel digestion method. Standard four-acid digestion procedures cause volatilization of germanium as germanium tetrachloride, resulting in systematic understatement of germanium grades. The sodium peroxide fusion method employed (ME-MS89L) prevents germanium chloride volatilization and is the appropriate closed-vessel method for germanium determination in sulfide and silicate matrices. Results generated by conventional four-acid methods are not directly comparable to results reported herein.
