T2 Metals Advances Its Sherridon Copper-Zinc-Gold-Silver Project in Manitoba, Canada, with Robust Historical Metallurgical Test Results
Historical results cover only one composite and one locked-cycle test; broader confirmatory work is planned.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Summary
T2 Metals (TWOSF) reported historical metallurgical results for its Sherridon project in Manitoba, with copper recovery reaching 97.4% in testing. A single 2011 locked-cycle flotation test, which recycles material through processing stages, used a Lost Lake composite grading 1.70% copper and 5.08% zinc. It produced a 28.3% copper concentrate and a 55.7% zinc concentrate, with zinc recovery of 90.1%.
The results exceeded expected Flin Flon concentrator performance at equivalent feed grades. However, the historical data have not been sufficiently verified to current NI 43-101 standards and may not represent all four Sherridon deposits. Samples from those deposits have been submitted for mineral characterization. T2 Metals plans confirmatory testing to support future economic studies and is evaluating toll milling and standalone processing. The rail-connected Flin Flon concentrator has been on care and maintenance since 2022.
How this balance works
Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.
It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.
Rhea-AI Sentiment measures something else, the tone of the wording.

Locked-Cycle Flotation Tests Returned
Vancouver, British Columbia--(Newsfile Corp. - October 7, 2026) - T2 Metals Corp. (TSXV: TWO) (OTCQB: TWOSF) (FSE: WJ6) ("T2 Metals" or the "Company") is pleased to report historical metallurgical test results from its Sherridon Copper-Zinc-Gold-Silver Project ("Sherridon" or the "Project") in Manitoba, Canada. Metallurgical tests demonstrate robust copper and zinc recoveries that exceed expected performance at Hudbay Minerals' ("Hudbay") nearby Flin Flon copper-zinc concentrator. The results provide a positive starting point for the Company's evaluation of processing options for Sherridon, while new mineral characterization is underway to guide further metallurgical testing across the Project's four deposits.
Highlights
Key results from the historical test work and the Company's ongoing metallurgical program include:
Locked-cycle flotation testing of a blended Lost Lake composite with a grade of
1.70% Cu and5.08% Zn achieved97.4% copper recovery to a28.3% Cu concentrate and90.1% zinc recovery to a55.7% Zn concentrate;Results exceeded expected Flin Flon concentrator performance at an equivalent head grade in both the copper and zinc circuits, attributed in part to lower pyrite/pyrrhotite content and favourable sulphide liberation in the Sherridon composite;
Results support T2 Metals' evaluation of processing options for Sherridon mineralization, including toll milling, as the Company advances the Project following its NI 43-101 Mineral Resource Estimate announced on May 7, 2026;
T2 Metals geologists have recently collected a set of semi-representative samples from across the four deposits (Bob, Cold Lake, Lost Lake and Jungle) which comprise the Sherridon resource. These mineralized samples have been dispatched for mineralogical characterization to compare with samples that were tested by Hudbay and support further metallurgical test work planning.
Mark Saxon, President & CEO of T2 Metals, said:
"Following our May 2026 resource estimate, Sherridon is the largest undeveloped copper project in central Canada. It has a rare advantage for a prospective mining project, with road and rail connectivity to a concentrator within an active mining community. This 2011 test work, commissioned by Hudbay, showed that Lost Lake mineralized rock concentrates efficiently when utilizing the Flin Flon flowsheet, delivering concentrate grades and recoveries above expectations due to favourable mineralogy.
"This knowledge provides a strong starting point for further metallurgical testing. As the Sherridon resource is comprised of four deposits, we have initiated a mineralogical study to expand our understanding of the variation in sulphide mineralogy prior to additional metallurgical test work."
Project Location
Sherridon is located within the Flin Flon–Snow Lake Greenstone Belt, one of the world's richest volcanogenic massive sulphide ("VMS") regions, which extends from east-central Saskatchewan to central Manitoba (see Figure 1). The Belt is a globally significant source of critical and precious metals, and is comprised of four districts: Hanson, Flin Flon, Sherridon and Snow Lake. It has supported more than a century of copper-zinc mining, including Hudbay's original Flin Flon mine and nearby 777 Mine, and the current and expanding Snow Lake operations.
The recent acquisition of Foran Mining by Eldorado Gold for the McIlvenna Bay Project provides a notable example of the strategic value being placed on VMS assets within the same Belt. Sherridon sits within this proven and historic mining region with multiple copper-rich NI 43-101 resources and two past-producing mines within an eight-kilometre radius.

Project Infrastructure & Logistics
Sherridon is located approximately 65 kilometres northeast of the city of Flin Flon (see Figure 2), where Hudbay's former 777 Mine and the Flin Flon concentrator are located. The concentrator was used to process copper-zinc VMS mineralization from numerous mines and has been on care and maintenance since 2022. It is connected to Sherridon by rail and provides a potential processing option for further evaluation as the Project advances.
In addition, Sherridon has an infrastructure advantage including year-round road access, an operational rail line that passes directly through the Project area, and nearby power. Sherridon is connected to established mining centres and operations including Flin Flon, Snow Lake and the McIlvenna Bay project, providing access to regional services, an experienced mining workforce and established transportation infrastructure.

Historical Metallurgical Data
Metallurgical drilling was completed at the Cold Lake and Lost Lake deposits by Hudbay, who operated the Sherridon Project from 2010 to 2013 under joint venture. Data from test work on mineralized core samples completed by G&T Metallurgical Services ("G&T") of Kamloops, British Columbia, in 2011 has been provided by Hudbay.
Testing evaluated the flotation response of various sulphide minerals using a flowsheet and reagent scheme designed to replicate Hudbay's Flin Flon concentrator, connected to Sherridon by an operational rail line.
Locked-Cycle Flotation Testing – 2011 Program (G&T Project KM2757)
In late 2010 and early 2011, G&T received approximately 166 kg of drill core from the Lost Lake deposit and prepared high-grade and low-grade composites. These were blended and tested using a flowsheet and reagent scheme designed to replicate the Flin Flon concentrator circuit, including a matched primary grind of 69 µm K80, copper and zinc rougher and cleaner stages, and recycling of copper scavenger concentrate and first cleaner tailings to the primary grind. A single locked-cycle test produced the results summarized in Table 1.
| Product | Weight (%) | Cu (%) | Zn (%) | Cu Recovery (%) | Zn Recovery (%) |
| Copper Concentrate | 6.1 | 28.3 | 3.14 | 97.4 | 3.8 |
| Zinc Concentrate | 8.1 | 0.27 | 55.7 | 1.2 | 90.1 |
| Rougher Tailings | 83.6 | 0.02 | 0.21 | 1.1 | 3.5 |
| Recalculated Feed | 100.0 | 1.70 | 5.08 | 100.0 | 100.0 |
Table 1: Locked-Cycle Flotation Test Results – 2011 Program
At a recalculated feed grade of
The zinc circuit also exceeded expected performance by approximately 4 percentage points in grade and 2 percentage points in recovery. G&T attributed this in part to the composite's lower pyrite/pyrrhotite content, approximately half that of typical Flin Flon flotation feed, and the correspondingly lower locking of chalcopyrite and sphalerite with iron sulphides. Bulk mineral analysis (QEMSCAN) indicated chalcopyrite liberation of just over
Significance to the Sherridon Project
The flotation response of the Lost Lake composite compares favourably with the documented performance of the Flin Flon concentrator, which has been on care and maintenance since 2022.
The results support the Company's evaluation of processing options for Sherridon, including toll milling at Flin Flon and standalone development scenarios. T2 Metals plans to use this historical dataset to design a confirmatory metallurgical program on recent drill core from across the Project's deposits to support future economic studies.
Historical Data Disclosure
The locked-cycle flotation results reported herein are historical in nature. They were generated in 2011 by G&T, an independent, accredited metallurgical testing laboratory, for a prior operator of the Project, and predate T2 Metals' involvement with Sherridon.
A qualified person has not completed sufficient work to verify the sample provenance, chain of custody, or laboratory QA/QC protocols underlying this test work to current NI 43-101 standards. The results are from a single composite and a single locked-cycle test, and may not be representative of the Sherridon deposits as a whole. The Company considers the data relevant to its evaluation of the Project's processing characteristics and intends to verify and build on it through confirmatory test work.
2026 Sampling and Next Steps
A selection of half core samples were collected by T2 Metals' geologists across each of the Sherridon deposits and mineralization types. Samples have been submitted to Dr. Tarryn Cawood's research team at University of British Columbia Okanagan for mineral and texture characterization.
These samples will undergo micro XRF and laser ablation for mineral and texture characterization related to mineralogy and mineral/metal deportment. T2 Metals is currently planning metallurgical studies for each of Sherridon's four mineral deposits (Lost, Cold, Bob, and Jungle).
First Nations Partnerships
Sherridon is located within the traditional and ancestral territory of the Kiciwapa Cree Nation, with whom T2 Metals has established a long-term, collaborative relationship, an important component of Sherridon's development planning.
In 2022, T2 Metals and the Kiciwapa Cree Nation signed an Exploration Agreement establishing a framework for cooperation, employment, community training and local economic participation in exploration activities at Sherridon. The Agreement was the first of its kind signed in Manitoba, reflecting the Company's commitment to building a long-term partnership with the Kiciwapa Cree Nation, and has been widely recognized for its meaningful contribution to reconciliation and community engagement.
Jurisdiction and Government Support
Manitoba is a tier-one mining jurisdiction with a long history of mineral production, an established infrastructure network and a supportive government committed to responsible mineral development. The province is also home to 30 of Canada's 34 identified critical minerals, highlighting its strategic importance in securing the global supply of mineral resources.
