Silver Tiger's El Tigre Results Lift Shares 6.2%

Silver Tiger Metals Inc. released exploration results from its 2026 Summer Program on the Northern Area of the 100%-owned El Tigre silver-gold project in Sonora, Mexico, plus confirmatory high-grade assays from 2025 geotechnical drilling inside the heap leach mine under construction; the shares last traded at 0.83, up 6.22% on the day.

Silver Tiger Metals Inc. (SLVTF) put out two sets of drill results on Friday covering its wholly owned El Tigre silver-gold project in Sonora, Mexico. One set came from the 2026 Summer Program on the project's Northern Area. The other was confirmatory assay work drawn from the 2025 geotechnical drilling campaign carried out from inside the El Tigre heap leach mine that the company is currently building.

The market took the combination well. Silver Tiger shares last traded at 0.83, a gain of 6.22% from the prior close of 0.78, and finished the session at the top of a day range of 0.80 to 0.83. That was a stronger move than the broad market managed: the S&P 500 tracker (NYSEARCA: SPY) closed at $764.29, up 0.85%, the Nasdaq 100 fund (NASDAQ: QQQ) at $714.88, up 0.87%, and the Dow tracker (NYSEARCA: DIA) at $525.79, up 0.97%. All figures are as of the last trade at 20:00 GMT on Friday, 11 September 2026, with markets now closed.

Two different kinds of drilling, two different jobs

It is worth separating what the two programs are actually for, because investors sometimes read every drill hole the same way.

The 2026 Summer Program on the Northern Area is exploration. Its purpose is to test ground that is not yet part of the mine plan and to work out whether the silver-gold system at El Tigre extends further than what has already been defined. Results from that kind of drilling matter for the long-run size of the deposit and for any future resource update, not for the tonnes that go through the plant next year.

The 2025 geotechnical campaign was something else entirely. Geotechnical holes are drilled to understand rock strength, fracturing and ground conditions so that engineers can design pit walls, underground openings and foundations safely. Assaying that core is opportunistic: the holes were drilled for engineering, and the samples were sent for analysis afterwards. Because those holes were collared from inside the heap leach mine now under construction, the assays function as a check on what the company already believes is there. The company described the results as confirmatory and high grade, which is the outcome an operator wants before it commits the remaining capital to a build.

Why confirmation inside a mine under construction carries weight

A heap leach operation is a comparatively simple way to recover metal. Ore is crushed, stacked on a lined pad, and irrigated with a leaching solution that dissolves the target metal for collection and recovery downstream. It is cheaper to build and quicker to start than a conventional mill, which is one reason smaller developers favour it, but it is also sensitive to grade and to how the rock behaves.

That is what makes drilling from inside the mine footprint useful in two directions at once. The geotechnical data supports the engineering. The assays, if they come back consistent with the block model, reduce the risk that the material fed onto the pad underperforms expectations once commissioning begins. Reconciliation risk — the gap between what a model predicts and what the pad actually delivers — is one of the most common reasons a newly built mine misses its first-year guidance.

The reported details of the release were carried by Baystreet.

Sonora, full ownership and the leverage that comes with it

El Tigre sits in Sonora, in northwestern Mexico, a state with a long mining history and established infrastructure and workforce. It is one of the more familiar addresses for North American silver and gold developers, though Mexican permitting and mining policy have been a live consideration for the sector in recent years.

Silver Tiger holds the project outright — 100% owned. Full ownership means no joint-venture partner takes a share of the output and no earn-in arrangement dilutes the company's exposure to good drill results. The flip side is that the company carries the full cost of construction and the full weight of any delay. For a single-asset developer, that concentration is the whole investment case: the share price tracks El Tigre and very little else.

What determines whether Friday's move sticks

A 6.22% day on exploration news is a reaction, not a re-rating. Several things will decide whether it holds.

• Continuity in the Northern Area. Isolated good intercepts are common; what changes a valuation is whether the mineralisation is continuous enough to be modelled and eventually converted into resources.
• Construction milestones at the heap leach mine. Pad lining, crushing circuit installation, first ore stacked and first metal poured are the dates that turn a developer into a producer.
• Funding. Building through to commercial production consumes cash. Any equity raise, streaming deal or debt facility disclosed between now and start-up will shape per-share economics.
• Silver and gold prices. Heap leach margins are thinner than a high-grade mill's, so the metal price environment at start-up matters disproportionately.
• A resource or economic update. Exploration results only become balance-sheet relevant once they flow into an updated resource estimate or a revised mine plan.

Reading a developer's news flow without over-reading it

Developers in the final stretch before production tend to generate a lot of headlines, and they are not all equal. Exploration results extend the story. Construction updates advance it. Financing news changes who owns the upside. Friday's release delivered on the first two categories at once — new ground tested, and existing expectations checked from inside the mine box — which explains why the stock outpaced the three major US benchmarks on a broadly positive session.

For shareholders, the practical question over the next several quarters is not how high the best intercept was but whether the build stays on schedule and whether the grade that reaches the leach pad matches the grade in the model. The confirmatory assays released Friday are a data point in favour. Commissioning will be the verdict.

Frequently asked questions

What did Silver Tiger Metals announce?

Silver Tiger Metals released exploration results from its 2026 Summer Program on the Northern Area of the El Tigre silver-gold project in Sonora, Mexico. The same release also detailed confirmatory, high-grade assay results from its 2025 geotechnical drilling campaign, with those holes drilled from inside the El Tigre heap leach mine that the company is currently building.

How did the shares react?

Silver Tiger stock last traded at 0.83, up 6.22% from a previous close of 0.78, finishing at the high end of a day range of 0.80 to 0.83 as of the last trade at 20:00 GMT on 11 September 2026. That gain outpaced the S&P 500, Nasdaq 100 and Dow trackers, which rose 0.85%, 0.87% and 0.97% respectively.

What is a heap leach mine?

Heap leaching is a metal recovery method in which crushed ore is stacked on a lined pad and irrigated with a chemical solution that dissolves the target metal. The pregnant solution is collected and processed to recover the metal. It is cheaper and faster to build than a conventional mill, but margins are more sensitive to ore grade and metal prices.

Why does geotechnical drilling produce assay results?

Geotechnical holes are drilled primarily to measure rock strength, fracturing and ground conditions so engineers can design safe pit walls, openings and foundations. Once that core is logged, it can also be assayed for metal content. Because the holes sit inside the known deposit, the assays serve as an independent confirmation of grades already assumed in the mine plan.

Where is the El Tigre project?

El Tigre is located in the state of Sonora in northwestern Mexico, a long-established mining district with existing infrastructure and an experienced workforce. Silver Tiger Metals owns the silver-gold project outright at 100%, meaning no joint-venture partner shares in output but the company also carries the entire cost and schedule risk of construction.

What should investors watch next?

The key items are construction milestones at the heap leach mine — pad lining, crushing circuit, first ore stacked and first metal poured — plus any financing announcements, an updated resource estimate incorporating the Northern Area drilling, and prevailing silver and gold prices at start-up, since heap leach margins are relatively thin.
