Sitka Gold's Rhosgobel deposit grows 250m east and 100m deeper, with a quiet tungsten kicker

## Rhosgobel keeps delivering: Sitka Gold extends the RC Gold deposit in every direction

The headline number is the headline hole. Sitka Gold's Hole 71 at the Rhosgobel deposit returned 159 metres of 1.14 g/t gold within a broader intercept of roughly 257m at 0.84 g/t gold, according to Mike Berkey, Sitka's director and VP of corporate development. But the bigger story sits in what those numbers imply about how much of Rhosgobel the team has yet to find.

### What the latest batch adds

The release covers 19 drill holes combining gold and tungsten results from Rhosgobel, part of the broader RC Gold Project in the Yukon. Berkey says 18 of the 19 holes hit mineralization better than 1 g/t in broad intervals, and the deposit still has open ends in every direction.

Three growth vectors stand out:

- **Strike extension to the east.** Drilling has pushed the known strike length to 1.6 kilometres, with the latest results extending the mineralized envelope 250 metres east of where 2025 drilling ended. Visual logging of holes farther east, including visible gold and sheeted veining (parallel, closely spaced mineralized fractures), suggests that extension continues. - **Depth extension.** Hole 58 cut mineralization at least 100 metres below the current pit-constrained resource envelope, a result Berkey describes as "staying strong at depth," and which keeps the option of a deeper pit shell on the table. - **Structural complexity.** Holes 71 and 72 were drilled obliquely to test a set of north-northwest structures that appear to offset the main east-west trend by less than 100 metres. Berkey argues these small offsets are why some earlier drill fences may have just clipped the edge of the deposit, and why future fences need to step north.

### Why "small offsets" matter for resource growth

In resource geology, an "offset" is a post-mineral fault that shifts the deposit sideways or up-and-down. If a fault offsets the mineralized body by even 30 to 50 metres, a drill hole collared on the wrong side can miss the main zone entirely. Sitka's current working model is that these north-northwest structures are creating small, sub-100-metre offsets of the main Rhosgobel trend. That finding matters because it means a portion of the existing drill pattern may not have fully tested the deposit.

The team says it will move drill collars north of the soil geochemical anomaly in the eastern part of the deposit to chase the offset trend. That is the kind of operational adjustment that often turns "missed ounces" into new resource.

### Tungsten as a quiet value-add

The second theme in the release is tungsten. Berkey describes recurring tungsten mineralization in the same sheeted veins that host the gold. Most assays are low-grade and bulk-tonnage in character, with occasional higher-grade hits. Tungsten prices have strengthened, and Sitka says it will incorporate tungsten credits into future economic studies. For investors, byproduct credits can meaningfully change project economics, particularly in a remote jurisdiction like the Yukon where unit costs run high.

### Scale and pace of the 2026 program

Sitka is in the middle of an unusually aggressive campaign for a junior. The company is running seven rigs across six target areas — Rhosgobel, Blackjack, Saddle, Eiger, Contact, Pukoman, and Bear Paw Breccia — all part of the Clear Creek Intrusive Complex. Roughly 43,000 metres of a planned 60,000-metre program has been drilled so far in 2026, with about 30,000 metres allocated to Rhosgobel alone.

The current Rhosgobel resource sits at 2.25 million ounces of gold, defined after only one year of drilling. Berkey's framing is direct: "we really don't know how big it is." That is unusual language from a company that already has a pit-constrained resource, and it tells you where the team thinks the discovery curve still sits. For context, "inferred" resources are estimates with lower geological confidence than "indicated" or "measured" categories, and require further drilling to upgrade. Until Sitka has tightened the deposit's edges, the team has elected to grow size first and confidence second. A small infill program is planned for later in 2026, focused on the higher-grade, greater-than-1 g/t core that comes to surface in the eastern part of the deposit — exactly the geometry that improves early-year payable ounces in a mine plan.

### The Blackjack comparison

Berkey draws a sharp line between Rhosgobel and the neighbouring Blackjack zone. Blackjack has been drilled to 1.1 kilometres depth, and the geological character at depth is being read as potentially underground-style mineralization — narrower, higher-grade veins below an open-pit shell. Rhosgobel, by contrast, is being framed as a near-surface, open-pit target with drilling largely confined to 300 to 400 metres. That distinction matters because the two deposit styles can support very different development pathways and capital intensities.

### What to watch next

Three near-term catalysts come out of this update:

1. Assays from holes 250 metres east of the current drilling, where visual mineralization including visible gold is already noted. 2. First drill results from the Contact, Pukoman, and Bear Paw Breccia targets, which sit close to known deposits and could feed a central processing facility. 3. End-of-year infill drilling at Rhosgobel, designed to convert a slice of inferred ounces to indicated, particularly in the higher-grade eastern core.

### Bottom line

The video's case for Sitka Gold rests on a simple proposition: a 2.25-million-ounce open-pit resource is growing along every axis on which a junior can grow it, with a tungsten credit sitting quietly alongside the gold. The deposit remains open in nearly every direction, and the 2026 drill program is sized to keep that story moving through year-end.
