1911 Gold Reports Positive Metallurgical Results of 93.7% for True North and 96.3% for Ogama-Rockland

1911 Gold Corporation (AUMB) released results on August 20, 2026, detailing metallurgical test outcomes for the True North and Ogama-Rockland properties, alongside an update on mill commissioning.

Metallurgical testing for True North utilized a 130 kg composite sample from Level 16, L10 Zone, V-1030 vein. The material exhibited a measured head grade of 1.82 g/t Au. Total gold recovery averaged 93.7%, with gravity recovery accounting for 51.0% of that total. Flotation concentrate captured 44.5% of the gold, while leach recovery from reground flotation concentrate averaged 95.5%. The leach residence time was recorded at 24–48 hours. The Bond Ball Mill Work Index was determined to be 14.1 kWh/t, placing the ore at the low end of medium hardness. Environmental work indicated no acid generation and no measurable deleterious metal leaching.

Testing for Ogama-Rockland was conducted on a composite from 2025/2026 drill core. The text reports a measured head grade of 4.65 g/t Au, while the release also notes an estimated head grade of 4.94 g/t Au based on half-core assays. Total recovery reached 96.3% using a Gravity-Flotation-Regrind-Leach process. Gravity recovery was 82.0%, and leach recovery from reground concentrate averaged 97.7%. The leach residence time for this process was 72 hours.

Regarding operations, 1911 Gold Corporation reported the successful commissioning run of the True North primary ball mill on August 10, 2026. The update noted the installation of new liners, lifters, and a gear lube system. The company is currently preparing for test mining and milling planned for later in 2026.

In administrative news, 125,000 DSUs were granted to four directors for Q2 2026 director fees.

1911 Gold Corporation (AUMB) reported a True North recovery of 93.7%, which aligns with the 93.5% mill recovery assumption disclosed in the Preliminary Economic Assessment (PEA) investor presentation. The Ogama-Rockland result showed a higher recovery of 96.3%, though the company noted this is preliminary, based on a single composite split and one full recovery test, and requires additional testing across more rock types and head grades.

The update also confirmed the primary ball mill commissioning, consistent with prior disclosures that targeted the mill to be operational in mid-2026, excluding the new crushing circuit.

The release does not change:

• Mineral resources or reserves.
• Mine life or production profile.
• Capital costs.
• Financing position.
• The production decision timeline.

The company’s PEA previously assumed an 11-year mine life, average annual production of 58,114 oz, and a mill recovery of 93.5%. The August 11, 2026 Ogama-Rockland resource update assumed 94% gold recoverability, making today’s results broadly consistent with those prior assumptions.

Risks that remain unchanged include:

• No production decision has been made.
• The company is pre-revenue and loss-making.
• A going concern flag is present in the latest MD&A.
• The PEA disclosure was previously corrected in July 2026 after review by the British Columbia Securities Commission.
• The company still needs additional financing and/or the Auramet Tranche 2 draw to fund through to production.

1911 Gold Corporation is an advanced gold explorer and developer focused on the 100%-owned True North Gold Project in the Archean Rice Lake Greenstone Belt, Manitoba, Canada. The company controls a land package of about 62,000 hectares with numerous past-producing gold operations. True North includes existing shafts, underground workings, a processing plant, tailings management facility, camp, and hydroelectric power access. The project is fully built and permitted, and the company is targeting a possible restart, with test mining in 2026 and a potential production decision in 2027.

Ogama-Rockland is a satellite gold project about 45 km by road southeast of True North. Its 2026 inferred mineral resource is 3,314,000 tonnes at 6.68 g/t Au, containing 712,000 ounces.

Historical context:

• True North operated until December 2022.
• Ogama and Rockland mines produced approximately 45,000 ounces at 11.25 g/t Au between 1948 and 1951.
