Brownfields tungsten rerate — Linka drilling and NOI progress

Tungsten is no longer just an industrial metal story. It is now a supply security story. Defence, aerospace, hard tooling and high-temperature industrial users need tungsten because it is dense, heat-resistant and hard-wearing. The problem is supply. China controls the bulk of global tungsten supply, and U.S. military and industrial buyers are being pushed to reduce that dependence under the REEShore and DFARS policy timetable into 2026 and 2027.

That creates a very specific market regime for junior tungsten names. The product is not a bulk commodity with open global liquidity. It is a strategic input with procurement friction, policy deadlines and a narrow buyer pool. When supply is tight and governments care about domestic or allied sourcing, projects with past production, existing infrastructure and a believable path to concentrate matter more than simple tonnage stories.

The financing backdrop is better than it was during the 2022 to 2023 tightening shock, but it is still selective. Fed funds are at 3.50% to 3.75% as of 18 March 2026, while the broader rates backdrop remains restrictive enough that weak juniors still struggle to fund long development runs. As of 31 March 2026, Viking had A$4.68m cash and a quarterly net burn of about A$696k, which gives it roughly 6.7 quarters of runway, but not a self-funded path through every Nevada catalyst and the Australian back-up assets.

The market is open, but only for stories that convert evidence into a financing case. For pre-revenue miners, that means the stock only gets real support when technical work turns into a compliant resource, a permit path and a funding structure that lowers dilution. Price strength alone does not close the capital gap.

Viking is tied to the part of the market that is getting the most policy attention, non-Chinese tungsten. That matters because the company is not trying to sell a broad exploration dream. It is trying to turn Linka into a brownfields U.S. tungsten supply option at a time when buyers are under pressure to secure exactly that type of material. If the market believes the project can produce saleable concentrate on a low-capex basis, Viking trades less like a generic explorer and more like a strategic developer with policy support behind it.

This is where the transmission matters. Tight tungsten supply lifts the strategic value of every validated ounce equivalent in the ground, but only if the project can move from historical data to modern proof. For Viking, that means drilling, metallurgy and permitting are not just technical tasks. They are the bridge between a small market capitalisation and a higher-value U.S. critical minerals platform. The current market cap of A$30.3m and enterprise value of A$25.1m as at 24 February 2026 shows the market is still pricing the story cautiously.

The Australian gold and vanadium assets sit behind that main trade. Riverina East keeps discovery upside alive, and Canegrass gives longer-dated critical minerals optionality, but neither changes the near-term funding equation like Linka does. The stock moves when Linka gets closer to a financeable restart path, while the scale case comes later if the wider Nevada district starts to look like a real tungsten platform.

1. 01REEShore and DFARS implementation steps, because policy deadlines are what keep tungsten in the spotlight.
2. 02Any U.S. defence funding or Defence Production Act grant application outcome, because non-dilutive money changes the funding mix.
3. 03Maiden drilling and validation results at Linka, because modern confirmation is what turns historical grades into investable data.
4. 04Metallurgical work, especially whether gravity-led recovery keeps pointing to a simple flowsheet and saleable concentrate.
5. 05Permitting progress and the Notice of Intent path, because timeline slippage pushes the story back toward dilution.
6. 06Any strategic capital from U.S.-linked partners, because cornerstone money reduces the cash burden on shareholders.

Bottom line: tungsten scarcity and U.S. policy are doing the heavy lifting, but Viking only gets paid by the market if Linka converts that backdrop into proof, funding and a real development path.

Viking becomes a U.S. tungsten restart story if Linka keeps converting old evidence into modern proof. If it works, this is not a generic explorer, it becomes a cash-flow generating brownfields developer with a staged pathway to saleable concentrate in Nevada.

That is why Linka matters most today. The stock does not need a giant discovery first. It needs validation drilling, metallurgy and permitting to keep shortening the gap between historical production and a financeable restart. The market is still valuing Viking at a small explorer level, with 2.334bn shares on issue, A$4.68m cash and net quarterly burn of A$696k at 31 March 2026. That gives roughly 6.7 quarters of runway, but not enough to drift. The failure condition is simple, if drilling or metallurgical work does not keep the restart case moving, the stock falls back to a diluted pre-resource explorer.

1. 01Linka, validation work is turning historical tungsten data into modern drill targets. That matters because the asset has past production, shallow intercepts and surface grades up to 14.7% WO3, but the market only pays for what is confirmed under modern standards.
2. 02Linka, metallurgy is pointing to a simpler flowsheet. Early testwork reported gravity upgrade from 1.3% WO3 feed to 22.9% WO3 rougher concentrate, then 63.6% WO3 cleaner concentrate, with combined gravity plus flotation recovery of 83.8%. That matters because a simpler process supports lower capex and a faster path to cash flow.
3. 03Linka, the brownfields footprint already exists. Historical ore treated was about 65kt through a 360tpd mill, and the project has pits, underground workings and access to power and logistics. That matters because most tungsten peers still need to build the plant and infrastructure first.
4. 04Nevada district portfolio, Linka is not a lone hole in the ground. The six-project tungsten package gives Viking district optionality around Linka, which can support shared infrastructure, target ranking and strategic interest if the lead asset keeps advancing.

Linka is the asset that matters most today because it is the nearest path to cash flow. Riverina East, Canegrass and Narndee all have optionality, but none of them currently offer the same sequence from historical production, to validation drilling, to resource definition, to a possible low-capex restart. That is the difference. Linka is a brownfields tungsten project with a past-producing footprint and early metallurgical evidence that saleable concentrate is plausible. Most peers in this part of the market still need to prove both the geology and the processing route before they can be financed.

This asset changes valuation now, not just eventually, because every step that confirms grade, continuity, metallurgy and permitting tightens the funding risk and makes the company look more like a developer than a concept stock. The current strategy is built around a rapid, low-CAPEX pathway, with near-term spend focused on field work, geophysics, surface mapping and sampling, metallurgical testwork, drill planning, permitting and resource definition. That is the engine. If Viking can show that Linka supports a modular scheelite concentrate operation, the stock can trade more like a restart platform than a broad explorer basket.

The staged ownership structure also matters. Viking is targeting 100% of the Nevada tungsten portfolio, but one 2% NSR still sits over the package, buyable down to 1% for US$2.0m. That does not break the story, but it is a real funding consideration. The upside case is not built on perfect conditions. It is built on proving enough with Linka to unlock strategic funding, defence-linked support or partner interest and reduce how much equity has to be issued to keep advancing the asset.

1. 01Permitting and NOI progress, because the restart timeline breaks if federal approvals slip behind drilling and modelling.
2. 02Validation drilling results, because Linka only re-rates if historical intercepts translate into a modern compliant resource story.
3. 03Metallurgical follow-up, because the gravity-first route only matters if larger samples keep supporting saleable concentrate.
4. 04Evidence of funding support, including defence-linked grants or cornerstone capital, because a low-capex plan still needs cash and dilution is the main risk.

Bottom line: Linka is the bridge from explorer valuation to a financed tungsten restart story, and the next 3 to 12 months decide whether that bridge holds.

Viking’s end state, if it works, is not a patchwork explorer. It becomes a U.S.-focused tungsten development platform with Linka as the bridge asset and the Australian portfolio as secondary monetisation optionality.

That matters because the market is still being asked to value the Australian assets as if they are the main story. They are not. First Hit, Riverina East, Canegrass and Narndee only become meaningful if they either throw off discovery upside or support a transaction. Until then, they deserve capital, but not the bulk of it.

1. 01First Hit, defined gold anchor, limited study maturity. Viking has an inferred resource of 83.8kt at 7.0g/t Au for 19,000oz, with a conceptual underground subset of 53.1kt at 7.2g/t Au for 12,400oz. It gives the portfolio a real gold base, but the company has already said the underground study is conceptual and does not support Ore Reserves or a production target.
2. 02Riverina East, real drill interest but still unproven. The project holds about 480km2 across roughly 25km of Zuleika Shear strike. Recent work includes a 2m at 23.6g/t Au visible-gold intercept at Bifrost South, plus large auger anomalies and nugget discoveries. That is enough to keep discovery upside alive, but not enough to justify a development premium.
3. 03Canegrass, large-scale critical minerals optionality. Canegrass carries a 146Mt inferred resource at 0.70% V2O5, with about 2.2 billion lb contained V2O5 and Stage 2 vanadium recovery reported at 89.3%. This is the scale asset in Australia, but it is heavier, slower and more funding-hungry than Linka.
4. 04Narndee, early-stage residual upside. Narndee spans about 75km2 over four exploration licences, with auger sampling completed across roughly 7km of strike and results still pending. It is a low-cost pipeline option, not a valuation anchor.

The Australian portfolio still matters because it gives Viking more than one shot on goal. But the value ranking is clear. First Hit is the cleanest gold reference point. Riverina East has the best chance of turning into a discovery story. Canegrass is the largest tonnage asset. Narndee is the earliest and least commercial.

That hierarchy matters for capital allocation. First Hit and Riverina East can justify modest, disciplined exploration spend because they have enough geological signal to keep the upside alive. Canegrass should not pull management into a big-capex path while Linka is being advanced. It is a strategic vanadium asset, not a near-term self-funded build. Narndee deserves the least capital because it still has no resource and no demonstrated economic pathway.

The paper value is not enough on any of these assets. First Hit still needs continuity and a real mine plan. Riverina East still needs drilling to prove whether the structural targets hold together at scale. Canegrass still needs a cleaner view on economics, flowsheet and capital intensity before it can be treated as financeable. Narndee still needs basic discovery work. Until then, these assets support the floor and the upside, but they do not change the fact that Linka is the project that can move Viking from explorer-style valuation toward a financeable development story.

1. 01First Hit study work. If the company advances beyond conceptual mining language into a credible mining plan, the asset becomes more than a resource headline.
2. 02Riverina East drill continuity. Step-outs around Bifrost South need to prove the intercepts are part of a repeatable system, not isolated hits.
3. 03Canegrass partnering or monetisation. If management pushes this asset toward a strategic deal, it confirms that the company is protecting cash for Linka rather than funding a second major build.
4. 04Narndee result quality. Pending auger results need to show a real target ranking outcome, otherwise this stays as cheap optionality only.

Bottom line: the Australian assets are support acts, not the main event, and they only deserve serious capital if they start converting into cash, a transaction, or a clear development path.
