Blue Star Extends Ataani Polymetallic System and Advances Critical Metal Targets in the High Lake Greenstone Belt

Blue Star Gold Corp. (BAU) released a statement titled "Blue Star Extends Ataani Polymetallic System and Advances Critical Metal Targets in the High Lake Greenstone Belt." However, the accompanying source materials do not contain the body of the news release, instead providing financial documents, an investor presentation, and price history without specific drill intercepts or grade intervals. Consequently, the specific data supporting the claim that the Ataani system has been extended is not available in the provided text.

The materials do confirm that Ataani is a 2024 VMS discovery located in the Roma Project area of the High Lake greenstone belt. This belt also hosts the Ulu gold system and a portfolio of critical-metal targets including copper, zinc, lead, silver, and gold.

Documented intercepts from prior releases and the investor deck for the Ataani discovery include 17.1 meters of massive sulphide grading 0.42% copper, 1.43% zinc, 9.19 g/t silver, and 0.13 g/t gold. This interval includes 2.0 meters at 10.95% zinc and 3.5 meters at 1.46% copper.

Contextual data from the region includes historic intercepts at Sand Lake of 21.0 meters at 2.71% copper (containing 0.17% zinc, 20.84 g/t silver, and 0.29 g/t gold) and 15 meters at 3.29% copper. Additionally, M MG’s High Lake deposit is located approximately 15 kilometers away, containing an indicated resource of 7.9 million tonnes at 3% copper and 3.5% zinc.

Blue Star Gold Corp. (BAU) is a micro-cap grassroots explorer with an established gold resource at Ulu. The company has approximately 189.7 million shares outstanding and ~C$36 million in market capitalization, with ~C$1.39 million in working capital. Management states this working capital is insufficient for the next 12 months, making the company reliant on financings; a director loan of C$2.73 million extends to 2028.

Because the company raises capital on news flow, exploration headlines are financing-supportive and can move the equity even without a resource hit. Consequently, a genuine extension of the Ataani polymetallic system is considered a positive for sentiment. The Ataani discovery, made in 2024, returned 17.1 meters of mineralized structure (MS) with modest grade. This anchor is not embedded in the current price; the stock has drifted to ~C$0.19, near the low end of its C$0.13-0.335 range, and has never re-rated on Ataani. The market is not currently pricing a repetition of a strong Ataani hole.

The provided text contains no assays, so any upside from an in-line or modestly better Ataani extension cannot be confirmed. The development advances the critical-minerals narrative, adding a second value dimension alongside Ulu gold, and supports the funding story. It does not change measurable aspects of the resource, mine life, or net asset value.

Blue Star Gold Corp. (TSX.V: BAU; OTCQB: BAUFF; FSE: 5WP0) is a Nunavut-focused gold and critical-minerals explorer operating within the 135 km High Lake greenstone belt. The company’s Ulu Gold Project, held under a 950 ha lease, hosts a Flood Zone shear-hosted Archean lode gold deposit. Measured and indicated resources total 2.204 Mt @ 7.87 g/t Au (558 koz), while inferred resources stand at 3.263 Mt @ 4.54 g/t Au (476 koz). Metallurgical testing suggests greater than 90% gold recovery. Infrastructure at the site includes an airstrip, camp, roads, and a 1.7 km decline extending to 150 m.

The company’s portfolio extends to the Hood River (~11,200 ha), Roma Project (~30,100 ha; comprising Ataani, Sand Lake, Chill-Juno, Cairo, West West, Stu, and South), and Auma (~12,000 ha; comprising Bamako and Penny Lane). Its critical-minerals and VMS portfolio includes Ataani, discovered in 2024 with 17.1 m of mineralized strike, and Sand Lake, which returned 21 m @ 2.71% Cu. The exploration target for Sand Lake is 3-5 Mt @ 2.3-3.6% CuEq. The area has a historical backdrop featuring MMG's High Lake deposit nearby.

Regarding infrastructure, the Grays Bay Road & Port project proposes a 230 km all-season road. The project is currently undergoing MPO referral as of March 2026, Building Canada Act Schedule 1 consultation in June 2026, and NIRB review.

Financially, Blue Star Gold Corp. holds working capital of C$1.39M, which management states is insufficient, alongside cash of C$2.34M. A director loan of C$2.73M carries a 3% interest rate and matures in 2028. Exploration spending for the first half of 2026 totaled C$2.13M, compared to C$0.26M in the first half of 2025.
