SAGA Metals Pushes Radar Into Stage 2 of Temas' Chloride Leach

Saga Metals Corp. (TSXV: SAGA; OTCQX: SAGMF; FSE: 20H) said it has moved its metallurgical collaboration with Temas Resources Corp. into Stage 2 detailed bench-scale optimization of Temas' proprietary Regenerative Chloride Leach technology on mineralization from the wholly owned Radar Critical Minerals Project near Cartwright, Labrador, an approximately eight-week program intended to produce first high-purity titanium, vanadium and iron samples and the engineering data for a Gate 2 decision on a proposed mini-pilot.

Saga Metals Corp. (TSXV: SAGA; OTCQX: SAGMF; FSE: 20H) has taken its metallurgical work with Temas Resources Corp. a step further, moving from first-pass validation into what the two companies call Stage 2 – Detailed Bench-Scale Optimization. The subject is Temas' proprietary Regenerative Chloride Leach, or RCL, process, applied to mineralization from Radar, the critical minerals project SAGA owns outright near Cartwright, on the Labrador coast.

The program runs roughly eight weeks. Its stated purpose is narrow and technical in the way that matters most at this stage of a project's life: establish leaching and downstream solvent-extraction parameters for titanium, vanadium and iron that can be reproduced run after run, turn out the first high-purity product samples, and assemble the engineering criteria needed for a Gate 2 decision on a proposed mini-pilot plant.

What a chloride leach has to prove before anyone builds anything

Hydrometallurgy is the part of a mining project where value is either created or quietly destroyed. A deposit can carry attractive grades and still fail, because the metals will not separate cleanly, or the reagents cost too much, or the process cannot be repeated at scale without drifting out of specification.

Leaching dissolves target metals out of crushed rock using a chemical solution. In a chloride system, the solvent is chloride-based rather than the sulphate chemistry more common in older titanium and vanadium routes. The "regenerative" element in Temas' branding points to recovering and recycling the leaching medium rather than consuming it once — the single biggest swing factor in operating cost for a process of this type. Solvent extraction, the downstream step SAGA and Temas are also tuning, is how the dissolved metals are pulled apart from one another and from impurities so that each can be precipitated as a saleable product.

That last word is the reason Stage 2 carries weight. Titanium, vanadium and iron are not sold as slurry. They are sold to specification, and buyers of pigment-grade titanium feedstock, vanadium chemicals or iron products test what arrives. Producing merchant-quality samples is the first tangible evidence that Radar mineralization can yield something a customer would sign for, as opposed to something that assays well in a report.

Gate decisions, and why the mini-pilot is the real prize

SAGA and Temas have framed the work as a staged gate process, with Stage 2 feeding a Gate 2 decision on a proposed mini-pilot program. That structure is deliberate and, for shareholders of a small exploration company, largely a good thing. Gates force a project to earn its next tranche of spending on evidence rather than enthusiasm. Bench-scale work is comparatively cheap; a pilot plant is not.

What a mini-pilot would add is continuity. Bench tests are batches — a set volume of material, a set duration, a set of conditions. A pilot runs material through the circuit continuously, which is where recycle streams, impurity build-up and reagent losses reveal themselves. No engineering firm will put its name to a process design, and no lender or strategic partner will underwrite one, on batch data alone. Getting to a credible Gate 2 package is therefore the step that converts Radar from a geological story into a process story with a path to a study.

The corollary is that Stage 2 is also where a project can stall. If reproducibility proves elusive, or the purity of the first samples falls short, the decision to defer a pilot is the correct one and the timeline lengthens. Investors reading the eventual results should watch less for a single recovery number and more for whether the companies describe the parameters as locked in, and whether they commit to the mini-pilot.

How the market has priced the collaboration so far

The trading response to metallurgical milestones at this end of the market is usually muted, because the news is incremental by design. SAGMF last changed hands at 0.28 in its most recent session, down 4.63% from a previous close of 0.30, having traded in a 0.28–0.30 band, according to market data as of 20:00 GMT on Sept. 28, 2026. That is a microcap quote in every sense: a two-cent range on the day is a meaningful percentage swing, and liquidity on the US over-the-counter line is thinner than on the company's home TSXV listing.

The backdrop was soft across the board. The S&P 500 tracker closed at $765.61, off 0.74%; the Nasdaq 100 proxy finished at $736.53, down 1.07%; and the Dow tracker ended at $514.02, lower by 0.67%. A broad risk-off session is not a verdict on a Labrador metallurgical program, but it is the tape into which the announcement landed, and small resource names typically have the least support when the indices are red.

Labrador, three metals, and the critical-minerals pitch

SAGA describes itself as a North American exploration company focused on critical mineral discoveries, and Radar fits the template that has drawn policy attention across Canada and the United States: a domestic source of inputs where processing capacity, not geology, is the constraint. Titanium and vanadium both sit on critical minerals lists in North America, and the reason is consistently the same — the rock exists on the continent, while the refining and chemical conversion steps largely do not.

That is what makes a processing collaboration the logical next move for a project like Radar rather than another round of drilling. Establishing that a novel chloride route can deliver high-purity titanium, vanadium and iron from this specific mineralization speaks directly to the gap in the supply chain. It also concentrates the risk: the project's value becomes partly a bet on someone else's proprietary technology performing as advertised on someone else's rock.

Details of the staged program were set out by SAGA in its announcement carried by INN Battery Metals.

The checkpoints worth marking

On an approximately eight-week schedule, the first substantive read on Stage 2 should come from the companies themselves rather than from any regulatory filing calendar. Three things will tell the story.

• Reproducibility. Whether the RCL leach and solvent-extraction conditions are reported as repeatable, not merely achieved once.
• Product quality. Whether the titanium, vanadium and iron samples are characterized as merchant-quality, and against which specifications.
• The Gate 2 call. Whether SAGA and Temas proceed to the proposed mini-pilot, defer it for further bench work, or restructure the collaboration.

Until those land, Radar remains a project with a defined process pathway and no confirmed flowsheet, held by a company whose shares trade in single-cent increments. That combination has produced both of the outcomes microcap investors know well. Stage 2 is the work that starts to narrow the range.

Frequently asked questions

What exactly did SAGA Metals announce?

SAGA Metals said it has advanced its collaborative metallurgical program with Temas Resources Corp. into Stage 2, detailed bench-scale optimization of Temas' proprietary Regenerative Chloride Leach technology, using mineralization from SAGA's wholly owned Radar Critical Minerals Project near Cartwright, Labrador. The program runs approximately eight weeks and targets first high-purity titanium, vanadium and iron product samples.

What is a Regenerative Chloride Leach?

It is Temas Resources' proprietary hydrometallurgical process. Leaching dissolves target metals out of crushed ore using a chemical solution; in this case the chemistry is chloride-based. The "regenerative" label points to recovering and reusing the leaching medium rather than consuming it, which is typically the largest operating-cost variable in a process of this kind.

What is the Gate 2 decision?

Stage 2 is designed to generate the engineering data needed to support a Gate 2 decision on a proposed mini-pilot program. Gate structures require a project to justify its next spending commitment on results rather than expectation. Clearing Gate 2 would move Radar from batch bench testing toward continuous piloting, a far more expensive and more informative stage.

Why does a mini-pilot matter more than bench tests?

Bench tests process fixed batches under fixed conditions. A pilot runs material through the circuit continuously, which exposes recycle-stream behaviour, impurity build-up and reagent losses that batch work can hide. Engineering firms and financiers generally will not underwrite a process design on batch data alone, so pilot results are usually the gateway to formal economic studies.

Where does SAGMF stock stand?

SAGMF last changed hands at 0.28, down 4.63% from a previous close of 0.30, with a day range of 0.28 to 0.30, as of 20:00 GMT on Sept. 28, 2026. The market was closed at that timestamp. It is a microcap quote, meaning small absolute price moves translate into large percentage changes and liquidity is limited.

Why are titanium and vanadium treated as critical minerals?

Both appear on North American critical minerals lists largely because the continent's constraint is processing rather than geology: the deposits exist, while refining and chemical conversion capacity is concentrated elsewhere. That is why a project like Radar is pursuing a processing collaboration, aiming to show a domestic route to saleable high-purity titanium, vanadium and iron products.
