Sitka Gold Hits High-Grade at Blackjack, Traces Mineralization 550m East Through Saddle Toward Eiger

## What's New

Sitka Gold Corp (TSXV: SIG) is mid-way through one of the largest drill campaigns in its history at the RC Gold Project in Yukon, and this update from director and VP of corporate development Mike Berkey focuses on results released on September 21 across three deposits: Blackjack, Saddle, and Eiger.

## Blackjack: High Grades at Depth

The headline result is hole 133 at Blackjack, a deeper hole designed to test continuity of mineralization below the current resource pit shell. It returned 141.5m at almost 2 g/t gold, including a higher-grade component of more than 80m at 3.2 g/t gold and 6m at almost 10 g/t gold.

In context, Blackjack currently hosts about 2.3 million ounces (indicated and inferred combined) at roughly 1 g/t gold. The deeper holes matter because they test whether the deposit can support an underground mining scenario — which Berkey notes typically requires grades above 2 g/t. Sitka has about half a dozen holes now testing that deeper potential below the current pit shell, and the grades seen so far sit well above that underground threshold.

Whether an underground component moves forward will depend on drill density: "we'll be looking at as we update our mineral resource estimate early in 2027," Berkey said, referring to whether the spacing of holes below the pit is tight enough to model an underground resource.

## Saddle Zone: Filling in the Gap

The Saddle zone sits within the conceptual Blackjack pit shell but, until this year's program, had not been drilled densely enough to be included in the Blackjack mineral resource estimate. With 13 new holes, the team has now traced mineralization 550m east from Blackjack toward Eiger, hitting intervals close to surface — one starting at 5m depth — and at depth.

Highlights from Saddle include 17.5m at 2.68 g/t gold and 40m at 1.5 g/t gold. The drilling is parallel to the slope, so intersections a few hundred metres down the hole are still close to surface, meaning the mineralization is largely outcropping along the ridge.

Geologically, the Saddle zone is seeing the same intrusive dikes and sills (granitic bodies, either steeply or shallowly dipping) that mark the Blackjack deposit, along with mineralized metasediments in contact with them. The connection through Saddle is what is changing the picture: lamprophyre dikes — markers of the extensional structure that carried the gold-bearing fluids — can be mapped straight through Blackjack, through Saddle, and into Eiger.

## Eiger and the Merge Question

At Eiger, the released drill holes are on the west side of the deposit, drilled parallel to slope, extending mineralization toward the west. Saddle sits to the west of Eiger and is extending mineralization to the east. Berkey notes the conceptual pit shells for Eiger and Saddle are only "a couple of hundred meters apart," and that drilling now is hitting mineralized rock in between.

The implication, as Berkey puts it: "those pits are likely getting very close together and going to merge." Combining pits under a single mining operation reduces waste rock and can simplify the eventual mine plan.

## Other Targets in the Complex

The 2026 drill program is not only about connecting the existing deposits. Berkey highlighted three additional targets within the Clear Creek Intrusive Complex core:

- **Roskalpa deposit**: described as the largest near-surface deposit in the project. Drilling is still ongoing and the limits have not yet been defined. - **Contact Pukoman zone**: a target where hole 113 last year returned 120m at 1.1 g/t gold. Drilling this year is aimed at producing an initial mineral resource estimate. - **Bear Breccia**: just off the western margin of Roskalpa, where limited prior drilling is being followed up to assess whether an initial mineral resource can be supported.

## Resource Update and What Comes Next

When Sitka updates the Blackjack mineral resource estimate in early 2027, the additions could come from the Saddle zone material — currently classified as waste — as well as the deeper Blackjack holes if an underground component is supported. At a 0.3 g/t cut-off, anything above that threshold technically adds ounces to the deposit.

Berkey frames the project not as a single-deposit story but as a multi-deposit complex: "having multiple deposits in a very close area... gives you flexibility in scheduling things. You don't... if you have a single deposit, there might be times... we have gaps in production because you got to do a pushback to access your ore." That flexibility, he argues, bodes well for a future mine plan.

## Catalysts Ahead

- ~50,000m of drilling completed; ~10,000m remaining - ~50–60 drill holes pending assays - Seven rigs turning - Program wrap expected late October - Updated Blackjack mineral resource estimate targeted for early 2027

For investors, the next data point is whether the pending assays continue to confirm the connection through Saddle, and whether the deeper Blackjack holes are dense enough to support an underground resource component.
