Sitka Confirms High-Grade Gold Zone at Blackjack with 141.5 Metres of 1.93 g/t Gold, Including 80.6 Metres of 3.20 g/t Gold and 6.0 Metres of 9.46 g/t Gold, and Expands Near-Surface Mineralization Across 550 Metres Within the Blackjack Resource Pit at Its

Sitka Gold Corp. (SIG) released assay results on September 21, 2026, from 16 diamond drill holes at the Blackjack deposit, the Saddle Zone, and the Eiger deposit at its RC Gold Project in the Yukon.

Key intercepts from the program include:

• Blackjack hole DDRCCC-26-133: 141.5 m of 1.93 g/t Au, including 80.6 m of 3.20 g/t Au and 6.0 m of 9.46 g/t Au.
• Saddle Zone hole DDRCCC-26-135: 17.5 m of 2.68 g/t Au beginning at 4.6 m depth.
• Saddle Zone hole DDRCCC-26-136: 14.2 m of 2.74 g/t Au beginning within 5 m of surface.
• Saddle Zone hole DDRCCC-26-137: 40.0 m of 1.51 g/t Au beginning at 211.0 m, including 10.0 m of 3.54 g/t Au.
• Saddle Zone hole DDRCCC-26-140: 71.2 m of 1.15 g/t Au, including 14.8 m of 3.63 g/t Au.
• Eiger hole DDRCCC-26-139: 30.5 m of 1.46 g/t Au, including 6.5 m of 6.15 g/t Au (and 1.5 m of 25.50 g/t Au in the headline bullets).

At the Saddle Zone, thirteen holes have now traced near-surface gold mineralization over approximately 550 m of strike east of the current Blackjack resource. All intersections fall within the Blackjack resource pit shell but outside the current mineral resource estimate. The Blackjack hole DDRCCC-26-133 is described as below the current resource shell, continuing a high-grade zone previously identified in holes 121 and 132, which supports underground potential beneath the pit. No from-depth was provided in the release text for this specific intercept.

At the Eiger deposit, step-out drilling has extended mineralization west of the current resource toward the Saddle Zone. The release notes that the two pits are currently 200 m apart and that the deposits "may ultimately form one larger, continuous gold system."

The 2026 exploration program is nearing completion, with approximately 50,000 m drilled across 116 holes out of a planned 60,000 m. Seven rigs remain active. The release does not include a new resource estimate, tonnage figures, or an economic study.

Sitka Gold Corp. (SIG) is an advanced explorer in the pre-Pre-Feasibility Study (PEA) stage, holding a total indicated and inferred resource of 5.12 million ounces of gold across the Blackjack, Rhosgobel, and Eiger deposits. The company has no reserves and no economic study in place, with a PEA planned for early 2027. As a non-producer, new drill results compete for attention against this substantial existing resource base.

The company’s market capitalization stands at approximately C$434 million, based on 433.9 million shares trading at C$1.00. This valuation implies a premium multiple of roughly C$85 per ounce of contained gold, or approximately C$336 per ounce for the indicated portion, despite the absence of net present value (NPV), all-in sustaining costs (AISC), or capital expenditure guidance. The current price reflects significant resource value and expectations for continued growth, rather than representing a cheap, un-priced option.

Historical benchmarks for the zone include hole 132, drilled on August 10, 2026, which returned 218.6 meters of 1.25 g/t gold and a separate 92.7 meters of 1.14 g/t gold, totaling approximately 379 gram-meters. Hole 128, drilled on July 13, 2026, returned 348.0 meters of 1.12 g/t gold, totaling 389.8 gram-meters. The recent hole 133 delivers approximately 273 gram-meters at a higher average grade of 1.93 g/t, compared to the 1.12–1.25 g/t grades seen in previous holes.

The stock closed at C$1.03 on September 22, 2025, and C$1.00 on September 18, 2026, remaining flat over the twelve-month period. This price is 22% below its 52-week high of C$1.29 set in October 2025, a period during which the resource grew from approximately 2.7 million ounces to 5.12 million ounces. Recent drill batches have moved the stock by low single digits; for instance, following the August 10 release of holes 132 and 129, the price rose from C$0.98 to C$1.03 before fading to C$1.00. Similarly, after the September 8 Rhosgobel results, the price moved from C$1.03 to C$1.07 before settling at C$1.02.

The Saddle Zone now features 13 assayed holes tracing approximately 550 meters of near-surface mineralization located inside the Blackjack pit shell but outside the current resource definition. This area is directly convertible into pit-constrained ounces in the next mineral resource estimate. Additionally, hole 133 confirms a third consecutive deep high-grade intersection below the resource shell, strengthening the underground exploration concept.

The release includes another batch of broad 1–2 g/t RIRGS intercepts from a project that has published roughly a dozen such results in the past twelve months, maintaining the same "open in all directions" framing. Against its own recently published holes, hole 133 represents a grade improvement on comparable-to-lower gram-metres, characterizing the result as in-line to better rather than a step change in the system's scale. The release confirms and modestly extends a known system without quantifying tonnage, cut-off, true width, or resource delta. At a valuation of approximately C$85 per ounce of contained gold, the equity already discounts continuous resource growth, serving as an incremental positive that supports the next mineral resource estimate.

Sitka Gold Corp. (TSXV: SIG, OTCQX: SITKF, FSE: 1RF) is a Canada-headquartered gold explorer focused on its Yukon operations. The company’s flagship asset is the 100%-owned RC Gold Project, a 447 km² contiguous property located in the Tombstone Gold Belt, approximately 100 km east of Dawson City. The site is road-accessible year-round via the Clear Creek Road from the Klondike Highway and sits roughly 32 km from the Yukon power grid. Ownership was consolidated to 100% following the accelerated Clear Creek acquisition from the Victoria Gold receivership, which was completed in August 2026 for US$6M in cash plus a 5.0% NSR reducible to 2.0% for US$10M.

The project features several deposits with pit-constrained resources based on a 0.3 g/t Au cut-off. The Blackjack deposit holds 1,291,000 oz indicated at 1.01 g/t and 1,044,000 oz inferred at 0.94 g/t. Rhosgobel contains 2,250,000 oz inferred at 0.70 g/t; this estimate also included 2,926,000 oz Ag and 51,345 t WO3 in May 2026, though those metals were subsequently excluded from the July 2026 gold-only technical report. The Eiger deposit holds approximately 535,000 oz inferred at 0.52 g/t. In total, the project comprises 1.29 moz indicated and 3.83 moz inferred resources.

The deposits exhibit a RIRGS style, characterized by near-surface, sheeted quartz veins that are non-refractory and potentially open-pittable, with an emerging underground component at Blackjack. Metallurgical testing indicates Blackjack and Eiger recoveries of 77.6-93% via gravity plus cyanidation, while Rhosgobel achieves 94.3% gold recovery via whole-ore cyanidation and 84.7% tungsten recovery in rougher concentrate. Silver recovery remains untested.

Sitka Gold also holds other assets, including Alpha Gold in Nevada’s Cortez trend and Burro Creek in Arizona, which holds a historical 2011 resource that does not meet NI 43-101 standards. Both assets were slated for spin-out into a new exploration company, as announced on March 12, 2026.

The company’s capital structure consists of 433,899,344 shares outstanding, 13,687,500 warrants with an average exercise price of C$0.36, and 17,750,000 options, resulting in a fully diluted count of 465,336,844. According to the company’s deck, cash stood at C$25.0M as of August 1, 2026, with no debt reported.

Prior-period financial results, not disclosed in today’s release, show that for the fiscal year ending December 31, 2025, SG&A was C$4.61M, matching an operating loss of C$4.61M. The net loss was C$5.93M (EPS -C$0.02), with cash of C$44.57M, total assets of C$101.24M, and total equity of C$84.96M. Capital expenditure was C$18.56M, and financing inflow was C$50.67M. The Q1 2026 MD&A cites a C$1.9M quarterly net loss, C$43.5M in cash, and no interest-bearing debt.
