T2 Metals Corp. (TSXV: TWO) (OTCQB: TWOSF) (FSE: WJ6) has released historical metallurgical test results from its 100%-owned Sherridon Copper-Zinc-Gold-Silver Project in Manitoba, Canada. The results, originally generated in 2011 by G&T Metallurgical Services for a prior operator, demonstrated copper and zinc recoveries exceeding the documented performance benchmarks of Hudbay Minerals' nearby Flin Flon concentrator. The announcement builds on T2 Metals' NI 43-101 Mineral Resource Estimate disclosed on May 7, 2026, and supports the company's evaluation of processing options including toll milling. Investors may be watching how these results inform the company's confirmatory metallurgical programme across Sherridon's four deposits.

Key Points

  • T2 Metals Corp. (TSXV: TWO) (OTCQB: TWOSF) (FSE: WJ6) announced historical metallurgical results for the Sherridon Project in Manitoba
  • Locked-cycle flotation testing of a Lost Lake composite achieved 97.4% copper recovery to a 28.3% Cu concentrate and 90.1% zinc recovery to a 55.7% Zn concentrate
  • Results exceeded Flin Flon concentrator benchmarks by approximately 4 percentage points in copper concentrate grade and 7 percentage points in copper recovery
  • Investors should watch progress on new mineralogical characterisation studies underway across all four Sherridon deposits

Lost Lake Flotation Results Surpass Flin Flon Concentrator Benchmarks

The 2011 locked-cycle flotation test, conducted by G&T Metallurgical Services on a blended Lost Lake composite grading 1.70% copper and 5.08% zinc, produced a copper concentrate grading 28.3% Cu with 97.4% recovery, and a zinc concentrate grading 55.7% Zn with 90.1% recovery. The copper circuit exceeded expected Flin Flon concentrator performance by approximately 4 percentage points in concentrate grade and 7 percentage points in recovery. The zinc circuit exceeded expected performance by approximately 4 percentage points in grade and 2 percentage points in recovery. G&T attributed the strong results partly to lower pyrite/pyrrhotite content relative to typical Flin Flon flotation feed.

Infrastructure Advantages Supporting Sherridon Processing Evaluation

The Sherridon Project sits approximately 65 kilometres northeast of Flin Flon, connected by an operational rail line to Hudbay's former Flin Flon concentrator, which has been on care and maintenance since 2022. The project also benefits from year-round road access and nearby power. The release states T2 Metals is evaluating processing options including toll milling at Flin Flon and standalone development scenarios. The company has received more than $500,000 in funding from the Manitoba Mineral Development Fund to support resource discovery and development at Sherridon.

Mineralogical Characterisation Programme Initiated Across Four Deposits

T2 Metals geologists have collected semi-representative samples from across Sherridon's four deposits — Bob, Cold Lake, Lost Lake, and Jungle — and dispatched them to Dr. Tarryn Cawood's research team at the University of British Columbia Okanagan for mineral and texture characterisation using micro XRF and laser ablation. The company noted that the 2011 historical test results are from a single composite and a single locked-cycle test and may not be representative of the full project. A qualified person has not yet verified the original sample provenance or laboratory QA/QC protocols to current NI 43-101 standards.
